Surgical Management of Peritoneal Surface Malignancy with Respect to Tumour Type, Tumour Stage and Individual Tumour Biology



abstract

Peritoneal tumour dissemination is still considered as a terminal disease. For the last two decades, cytoreductive surgery (CRS) combined with intraoperative hyperthermic chemotherapy (HIPEC) has been popularised by Paul Sugarbaker almost doubling survival in selected patients compared with systemic chemotherapy alone. Nowadays, this particular treatment protocol is available in comprehensive cancer centres with reasonable mortality and morbidity. However, patient selection is still challenging. In general, CRS and HIPEC is indicated in primary peritoneal tumours such as mesothelioma and pseudomyxoma peritonei as well as in peritoneal metastases derived from gastrointestinal malignancies and ovarian cancers. Since systemic tumour spread is uncommon in patients with peritoneal metastases, peritoneal tumour dissemination was defined as localised disease within the "compartment abdomen". However, CRS and HIPEC are only beneficial as long as complete cytoreduction is achieved (CC-0 or CC-1). Histopathological parameters, the Sugarbaker peritoneal carcinomatosis index (PCI) and general condition of the patient have been established as patient selection criteria. In primary peritoneal cancers, individual tumour biology is the predominant criterium for patient selection as opposed to intraabdominal tumour load in peritoneal metastases derived from gastrointestinal cancers. In gastric cancer, CRS and HIPEC should be restricted to synchronous limited disease because of its biological aggressiveness. In patients with free floating cancer cells without macroscopic signs of peritoneal spread, however, CRS and HIPEC following preoperative "neoadjuvant" chemotherapy preserves chances for cure. So far, there is no general recommendation for CRS and HIPEC by clinical practice guidelines. In the recent S3 guideline for treatment of colorectal cancer, however, CRS and HIPEC have been included as possible treatment options.
 

Evaluation after five years of the cancer genetic counselling programme of Valencian Community (Eastern Spain)



abstract

 To evaluate the cancer genetic counselling programme in Valencian Community using intermediate indicators. Descriptive analysis of organisational and effectiveness indicators from the start in 2005 until December 2010: correct referral of patients according to the area from where they were referred (primary or hospital-based care) and syndrome; families identified as having each syndrome; suitability of the genetic testing for individuals with a cancer diagnosis (index cases, IC) and relatives of ICs with mutations; family size; and results of genetic testing on genes, ICs and relatives. 9,942 individuals attended, 87.7 % were referred by hospital-based care and 8.4 % by primary care. 7,516 patients (79 %) fulfilled cancer genetic counselling criteria (82 % from hospital-based care and 46 % from primary care). Amongst those who fulfilled the criteria, 59 % of referrals were related to hereditary breast ovarian cancer syndrome and 32 % to hereditary non-polyposis colorectal cancer. ICs were found in 3,082 families (78.7 %) and genetic testing was carried out on 91.3 % of them. Pathogenic mutations were detected in 21.8 % of the ICs and the testing was then offered to their relatives (an average of 3 per IC). Pathogenic mutations were found in 54 % of the assessed relatives. Results in 5 years confirm the appropriateness of these facilities, as part of an integrated health service, to identify families and individuals with genetic risk to offer them personalized counselling. Improvements have to be made with regard to the information given to both health professionals and patients about the risk criteria for various syndromes

Serum protein profile at remission can accurately assess therapeutic outcomes and survival for serous ovarian cancer



open access/full free text

Abstract

BACKGROUND:

Biomarkers play critical roles in early detection, diagnosis and monitoring of therapeutic outcome and recurrence of cancer. Previous biomarker research on ovarian cancer (OC) has mostly focused on the discovery and validation of diagnostic biomarkers. The primary purpose of this study is to identify serum biomarkers for prognosis and therapeutic outcomes of ovarian cancer.

EXPERIMENTAL DESIGN:

Forty serum proteins were analyzed in 70 serum samples from healthy controls (HC) and 101 serum samples from serous OC patients at three different disease phases: post diagnosis (PD), remission (RM) and recurrence (RC). The utility of serum proteins as OC biomarkers was evaluated using a variety of statistical methods including survival analysis.

RESULTS:

Ten serum proteins (PDGF-AB/BB, PDGF-AA, CRP, sFas, CA125, SAA, sTNFRII, sIL-6R, IGFBP6 and MDC) have individually good area-under-the-curve (AUC) values (AUC = 0.69-0.86) and more than 10 three-marker combinations have excellent AUC values (0.91-0.93) in distinguishing active cancer samples (PD & RC) from HC. The mean serum protein levels for RM samples are usually intermediate between HC and OC patients with active cancer (PD & RC). Most importantly, five proteins (sICAM1, RANTES, sgp130, sTNFR-II and sVCAM1) measured at remission can classify, individually and in combination, serous OC patients into two subsets with significantly different overall survival (best HR = 17, p<10(-3)).

CONCLUSION:

We identified five serum proteins which, when measured at remission, can accurately predict the overall survival of serous OC patients, suggesting that they may be useful for monitoring the therapeutic outcomes for ovarian cancer.
 

Annexin A4 Is Involved in Proliferation, Chemo-Resistance and Migration and Invasion in Ovarian Clear Cell Adenocarcinoma Cells



open access (technical)

 ..... CCC is the second most common EOC subtype after HGSC. More than 50% of inactivating mutations in the AT-rich interactive domain 1A gene (ARID1A), almost 40% of activating mutations in the gene encoding the catalytic subunit of phosphatidylinositol 3-kinase (PIK3CA), and microsatellite instability characterize the genetic alterations in CCC [1]. A recent large-cohort study found a pattern in CCC of resistance to standard platinum-based chemotherapy, which offers poor prognosis for patients diagnosed in advanced clinical stages (i.e., International Federation of Gynecology and Obstetrics stages III and IV) [2]. The ratio of CCC among EOC in Japan is reported to be higher than that in Western countries (15–25% and 5–12%, respectively); ethnic or geographical differences in its incidence have also been noticed [3]......

Results

ANXA4 was highly expressed in CCC specimens

Images corresponding to each representative IHC score and a summary of the results are shown in Figure 1A and B. All 52 CCC specimens demonstrated significant staining for ANXA4 (IHC score 5 or 6) without exception, with P<0.05 against all other types of ovarian carcinomas and LMP tumors (Figure 1B). In carcinoma cases, although few cases were available for IHC, all four mucinous carcinomas and two of six endometrioid carcinomas showed high levels (IHC score 4 or greater) of ANXA4 expression. Conversely, all three poorly or undifferentiated carcinomas and 13 of 14 SC expressed no detectable ANXA4. Only two mucinous adenomas were examined, but both of them showed an IHC score 6 expression of ANXA4, presenting a similarity to their malignant counterpart. Only one case of normal premenopausal ovary was available for IHC, but no ovarian components, including surface epithelium, follicles, and stromal tissues, were reactive for ANXA4.....



Is the Two-Tier Ovarian Serous Carcinoma Grading System Potentially Useful in Stratifying Uterine Serous Carcinoma? A Large Multi-Institutional Analysis



abstract

Highlights

140 patients with uterine serous carcinoma from three academic institutions were studied.
All cases were graded using MDACC two-tier grading system as low grade and high grade
The prognostic utility of application of MDACC two-tier grading system to uterine serous carcinoma is not applicable

Objective

A subset of uterine serous carcinoma (USC) may have better clinical behavior bringing up the possibility that there may be morphologic features, which would help in their categorization. The aim of this study is to evaluate the potential use of the MD Anderson Cancer Center 2-tier grading system for ovarian carcinoma in USC.

Conclusion

The presence of atypia and mitosis across a uterine serous carcinoma is notoriously variable in magnitude and extent, potentially making evaluation of these features difficult and subsequent grading subjective. Our findings thus show that actual prognostic utility of application of MDACC two-tier grading system to uterine serous carcinoma may not be applicable

Profile of panobinostat and its potential for treatment in solid tumor



open access

Ovarian cancer
Observations in preclinical studies using several human ovarian cancer cell lines have identified panobinostat to have synergistic effects with drugs commonly used to treat ovarian cancer, such as gemcitabine, paclitaxel, docetaxel, and 5′-DFUR (metabolite of capecitabine).57,58 Additionally, the treatment of panobinostat in combination with cisplatin of ovarian cancer previously resistant to cisplatin may be a viable treatment option based upon preclinical data showing that the presence of panobinostat lowered the inhibitory concentration for cisplatin in previously cisplatin resistant ovarian cancer cell lines.59 

E2 and LDX for the Treatment of Cognitive Complaints After Oophorectomy

First received: October 30, 2013

Purpose
This project seeks to address cognitive disturbance, which is a frequent adverse sequelae of risk reducing bilateral salpingo-oophorectomy (RRSO) with or without post-procedure chemotherapy and adjunctive treatments. RRSO after completion of childbearing is recommended for prevention of ovarian and breast cancer in women with BRCA1/BRCA2 mutations and standard of care for women with some forms of hormone-responsive cancer. Knowledge regarding the impact of this procedure, with or without chemotherapy, and subsequent hypogonadism on brain health is less than adequate. Premenopausal women who undergo an acute surgical menopause are at greater risk for verbal memory decline and executive function (EF) complaints, but as of yet, we cannot predict who is going to experience these adverse sequelae, nor do we have targeted prevention or treatment strategies other than hormone therapy, which is not an option in many cases and not always effective. An idealized sample as women who are planning for a RRSO will undergo brain imaging and behavioral assessments pre- and post-surgery as well as pre-/post-treatment with E2 or the psychostimulant, lisdexamphetamine (LDX; Vyvanse®).

End-of-life care pathways for the dying (lack of evidence) Cochrane Review update



Cochrane Summaries

Background
End-of-life pathways are used for people who are in the last days of their life to guide care, aid decision making and provide efficient care. This review examined whether using end-of-life care pathways in caring for the dying was effective.
Study characteristics
We searched scientific databases for clinical trials in which the effect of the end-of-life care pathway was compared with a control group that received usual care or with trials comparing one end-of-life care pathway with another end-of-life care pathway. Participants were to be patients, carers and families who received care guided by an end-of-life care pathway. There were no restrictions on age of the patient, diagnosis or setting (hospital, home, nursing home).
Key results
We found no studies fitting our criteria.
Quality of evidence
We could not locate any high-quality controlled studies that could answer this important question; despite concerns about the Liverpool Care Pathway (the most commonly used end-of-life care pathway). It is important for health services to base their care on high-quality evidence. Until such evidence is available, the use of end-of-life care pathways should be avoided. Large randomised controlled trials (where patients are allocated to treatments or groups using a random method) or other well-designed controlled studies are required for evaluating the use of end-of-life care pathways in caring for dying people in various clinical settings. Future studies should measure positive as well as negative outcomes for patients, families, carers and health professionals.

Main results: 
The original review identified 920 titles. The updated search found 2042 potentially relevant titles (including the original 920), but no additional studies met criteria for inclusion in the review update.
Authors' conclusions: 
With sustained concerns about the safety of the pathway implementation and the lack of available evidence on important patient and relative outcomes, recommendations for the use of end-of-life pathways in caring for the dying cannot be made. Since the last version of this review, no new studies met criteria for inclusion in the review update. With recently documented concerns related to the potential adverse effects associated with Liverpool Care Pathway (the most commonly used end-of-life care pathway), we do not recommend decision making based on indirect or low-quality evidence. All health services using end-of-life care pathways are encouraged to have their use of the pathway, to date, independently audited. Any subsequent use should be based on carefully documented evaluations. Large RCTs or other well-designed controlled studies are urgently required for the evaluation of the use of end-of-life care pathways in caring for dying people in various clinical settings. In future studies, outcome measures should include benefits or harms concerning the outcomes of interest in this review in relation to patients, families, carers and health professionals.

PD-1 targeting in cancer immunotherapy



open access

"....It is interesting to note that the anti–PD-1 MoAb demonstrated clinical objective responses in patients with previously presumed “nonimmunogenic” tumor types, including non-small cell lung cancer (NSCLC) and ovarian cancer, in whom durable partial responses (PRs) and stable disease were observed.[10] ....

Sequencing study underscores difficulty of treating ovarian cancer, points to diverse patterns of ovarian cancer evolution



Medical News Today

"One of the most comprehensive studies of genetic mutations in ovarian cancer has been published, demonstrating an unprecedented level of genetic variation that exists in both primary tumors and metastatic lesions of ovarian cancer. The study highlights potential new pathways for therapeutic intervention and suggests that sampling and sequencing of multiple disease sites may be required for effective targeted treatments.
The paper, titled "Genomic and transcriptomic plasticity in treatment-naïve ovarian cancer," is available online at the journal Genome Research and is authored by scientists at the University Medical Center Utrecht in The Netherlands and Life Technologies Corporation in Carlsbad, Calif. With an annual global incidence of 220,000 and mortality of 140,0001, ovarian cancer is a leading cause of cancer deaths in women, making it a disease in urgent need of improved treatment.
The researchers examined a total of 27 archived tumor biopsy samples, both from primary tumors as well as distant metastatic sites, gathered from three women with late stage (IIIC/IV) ovarian cancer. Tumor samples and matched normal tissue samples were analyzed using a variety of methods, including transcriptome and mate-pair sequencing and several targeted gene sequencing panels. Sequencing was conducted on the Applied Biosystems® SOLiD 5500xL and Ion Personal Genome Machine (PGM™), both from Life Technologies, using Life's Ion AmpliSeq™ Comprehensive Cancer Panel, a panel of more than 400 genes that have been implicated in cancer. This study represents the first peer-reviewed, scientific publication employing this panel of 409 oncogenes.....
 

Retrospective analysis of outcomes of secondary debulking surgery for recurrent epithelial ovarian cancer with favorable prognostic factors



abstract

Aim

Ovarian cancer is the second most common gynecological malignancy, yet it has the highest case-fatality ratio of all gynecologic malignancies. Surgery followed by combination platinum-taxane chemotherapy is the standard approach to the management of primary epithelial ovarian cancer. However, standard treatment of patients with recurrent ovarian cancer remains poorly defined. Secondary cytoreductive surgery (SDS) at the time of relapse has been proposed as a means of improving the prognosis of recurrent ovarian cancer patients with a treatment-free interval of at least 6 months.

Methods

In the present study, we retrospectively collected 16 patients with recurrent epithelial ovarian cancer who might benefit most from SDS and evaluated the impact of SDS on the outcomes for this highly select patient group.

Results

We found that SDS led to excellent outcomes, with a 73.1% 8-year overall survival rate after initial treatment, a 67.9% 5-year overall survival rate after prior SDS, and a 31.3% 5-year progression-free survival rate after prior SDS. Although the findings were not significant, these results suggest that repeated SDS might improve outcomes for this patient group.

Conclusion

The present study may provide a platform for discussion of the impact of aggressive or repeated SDS on the survival of patients with recurrent epithelial ovarian cancer and favorable prognostic factors. Further multi-institutional studies with larger number of patients are mandatory to confirm the present findings.

What We Do
Sisters in Survival works directly with gynecologic oncologists, medical imaging centers, and other community partners to provide medications and diagnostic procedures to ovarian cancer patients who, otherwise, could not afford them.
Ovarian cancer is an equal opportunity enemy. It does not strike based on one’s ability to pay. While some can afford to fight it head-on with everything in the medical arsenal, others are forced to forgo anti-nausea medications because—even with insurance—they can’t afford the high cost of the co-payments.

Navigating uncharted waters: a guide to shared decision making



Patient-Voice 

'Nothing about us without ushas been the rallying call for cancer advocacy that has helped to expose the lack of patient voices in decisions about care and treatments. Since the 1990s, enlightened doctors and healthcare organisations, aware of the hierarchical nature of the physician–patient relationship, have joined the movement to better inform people so they can be part of decisions, and the result is that in many countries the picture has radically improved. There is no doubt that attitudes about truth telling and provision of information – as witnessed by the proliferation of patient decision aids and websites – have changed for the better.

In turn, this has led to the rise of shared decision making (SDM) – which is defined, briefly, as involving a patient in a decision to the extent they would wish by providing and discussing information about options. It has become a topic that has attained specialist status, at least when judged by the number of research groups, conferences and organisations reporting and adopting shared decision making.

In 2010 the Salzburg Statement on Shared Decision Making was agreed at a global seminar (http://tiny.cc/SDM), which issued a call to clinicians, policymakers and patients to work together

Abstract

Elevated Plasma Vitamin B12 Levels as a Marker for Cancer: A Population-Based Cohort Study



open access

In conclusion, our study showed that high plasma Cbl (cobalamin) levels increased the risk of subsequently diagnosed cancer, mostly within the first year of follow-up. However, this association was not present for all cancer types. Although our results may have clinical implications for interpreting high Cbl levels, further studies are warranted to examine the possible diagnostic value of high plasma Cbl levels.

Tumor Growth Rate (TGR) is an early indicator of anti-tumor drug activity in phase I clinical trials



abstract

Purpose: RECIST evaluation does not take into account the pre-treatment tumor kinetics and may provide incomplete information regarding experimental drug activity. Tumor Growth Rate (TGR) allows for a dynamic and quantitative assessment of the tumor kinetics. How TGR varies along the introduction of experimental therapeutics and is associated with outcome in phase I patients remains unknown. 

Experimental designs: Medical records from all patients (n=253) prospectively treated in 20 phase I trials were analyzed. TGR was computed during the pre-treatment period (REFERENCE) and the EXPERIMENTAL period. Associations between TGR, standard prognostic scores (RMH score) and outcome (PFS, OS) were computed (multivariate analysis). 

Results: We observed a reduction of TGR between the REFERENCE vs. EXPERIMENTAL periods (38% vs. 4.4%, P<.00001). Although most patients were classified as stable disease (65%) or progressive disease (25%) by RECIST at the first evaluation, 82% and 65% of them exhibited a decrease in TGR, respectively. In a multivariate analyses, only the decrease of TGR was associated with PFS (P=.004), whereas the RMH score was the only variable associated with OS (P=.0008). Only the investigated regimens delivered were associated with a decrease of TGR (P<.00001, multivariate analysis). Computing TGR profiles across different clinical trials reveals specific patterns of antitumor activity. 

Conclusions: Exploring TGR in phase I patients is simple and provides clinically relevant information: (i) an early and subtle assessment of signs of antitumor activity; (ii) independent association with PFS; and (iii) It reveals drug-specific profiles; suggesting potential utility for guiding the further development of the investigational drugs.
 

Germline and Somatic Mutations in Homologous Recombination Genes Predict Platinum Response and Survival in Ovarian, Fallopian Tube, and Peritoneal Carcinomas



abstract

Purpose: Hallmarks of germline BRCA1/2-associated ovarian carcinomas include chemosensitivity and improved survival. The therapeutic impact of somatic BRCA1/2 mutations and mutations in other homologous recombination (HR) DNA repair genes is uncertain. 

Experimental Design: Using targeted capture and massively parallel genomic sequencing, we assessed 390 ovarian carcinomas for germline and somatic loss-of-function mutations in 30 genes, including BRCA1, BRCA2, and 11 other genes in the HR pathway

Results: 31% of ovarian carcinomas had a deleterious germline (24%) and/or somatic (9%) mutation in one or more of the 13 HR genes: BRCA1, BRCA2, ATM, BARD1, BRIP1, CHEK1, CHEK2, FAM175A, MRE11A, NBN, PALB2, RAD51C, and RAD51D. Non-serous ovarian carcinomas had similar rates of HR mutations to serous carcinomas (28% vs. 31%, p=0.6), including clear cell, endometrioid, and carcinosarcoma. The presence of germline and somatic HR mutations was highly predictive of primary platinum sensitivity (p=0.0002) and improved overall survival (p=0.0006), with median overall survival 66 months in germline HR mutation carriers, 59 months in cases with a somatic HR mutation, and 41 months for cases without an HR mutation. 

Conclusions: Germline or somatic mutations in HR genes are present in almost one-third of ovarian carcinomas, including both serous and non-serous histologies. Somatic BRCA1/2 mutations and mutations in other HR genes have a similar positive impact on overall survival and platinum responsiveness as germline BRCA1/2 mutations. The similar rate of HR mutations in non-serous carcinomas supports their inclusion in PARP inhibitor clinical trials.

Ocular adverse events of molecularly targeted agents approved in solid tumours: A systematic review



abstract

When using molecularly targeted agents (MTAs), oncologists and patients face new and sometimes unexpected toxicities. Though ocular adverse events (OAEs) are not uncommon with chemotherapy, they are rarely severe or dose limiting. Ocular toxicity profile may differ with MTAs, indeed severe and dose limiting toxicities have been described with targeted therapies currently under investigation. Our study aimed to review OAEs experienced with MTAs approved in solid tumours. This review revealed that many OAEs, frequent and potentially severe, exist and concern most MTAs. The suggestion is prompt referral of patients with severe pain and/or visual impairment to the ophthalmologist since these symptoms can be associated with potentially severe OAE and need ophthalmic assessment. Oncologists must be aware of such events and their potential severity for better treatment and better diagnosis in daily practice as well as in clinical trials

Trabectedin plus pegylated liposomal doxorubicin: the return of a treatment option for ovarian cancer (+other)



Future Oncology, Future Medicine

December 2013
Sections:

Manufacturing difficulties resulted in a shortage of pegylated liposomal doxorubicin (PLD), but these problems have recently been resolved and PLD is now available again. It follows that oncologists now have access to this important anticancer therapy and the combination of trabectedin (Yondelis®, PharmaMar, Madrid, Spain) plus PLD can once more be prescribed for the treatment of relapsed ovarian cancer, the topic under discussion at this symposium.

Today we have a much greater understanding regarding which patients with ovarian cancer in particular will benefit the most from treatment with trabectedin plus PLD:


▪ The first group involves patients with partially platinum-sensitive disease;

▪ The second group includes patients fully platinum-sensitive but who, for whatever reason, cannot be retreated with platinum therapy.

These are important clinical problems that oncologists have to deal with in their daily practice and in this symposium we count on eminent experts in the field to present some of the most recent data on these topics under the chairmanship of Andres Poveda (Instituto Valenciano de Oncología, Valencia, Spain) and Eric Pujade-Lauraine (Hôpital Hôtel-Dieu, París, France). Key speakers at the symposium are Nicoletta Colombo (European Institute of Oncology, University of Milan, Bicocca, Milan, Italy), Maurizio D‘Incalci (IRCCS – Istituto di Ricerche Farmacologiche Mario Negri, Milan, Italy), Antonio González (MD Anderson Cancer Center, Madrid, Spain) and Isabel Ray-Coquard (Centre Léon Bérard, Lyon, France). To discuss the findings that are presented with the goal of providing an overall perspective we have the following experts: Jalid Sehouli (European Competence Center for Ovarian Cancer, Charité University Hospital, Berlin, Germany), Josep M del Campo (Vall d‘Hebron University Hospital, Barcelona, Spain) and Domenica Lorusso (Fondazione `IRCCS‘ National Cancer Institute, Milan, Italy).

Biology of ovarian cancer and trabectedin mechanism of action, Future Oncology, Future Medicine



abstract

Symposium Paper

More than 50% of patients with ovarian cancer have genetic alterations in the homologous repair pathway. Trabectedin  (Herceptin)appears to induce damage more readily in tumor cells with defects in the homologous repair system. Moreover, trabectedin inhibits monocyte differentiation into tumor-associated macrophages and inhibits the production of inflammatory mediators such as IL-6. In patients with platinum-sensitive, relapsed ovarian cancer, trabectedin plus pegylated liposomal doxorubicin was associated with a trend towards improved overall survival by extending the platinum-free interval. These clinical effects could possibly be attributed to actions of trabectedin on the tumor microenvironment (e.g., a reduction of IL-6). Thus, trabectedin is an agent with mechanisms of action especially appropriate for targeting key processes in the biology of ovarian cancer.
 

Pharmacokinetics and Imaging of 212Pb-TCMC-Trastuzumab After Intraperitoneal Administration in Ovarian Cancer Patients



abstract

Purpose: Study distribution, pharmacokinetics, and safety of intraperitoneal (IP) 212Pb-TCMC-trastuzumab in patients with HER-2-expressing malignancy.

Experimental Design: IP 212Pb-TCMC-trastuzumab was delivered, after 4 mg/kg intravenous (IV) trastuzumab (Herceptin), to 3 patients with HER-2-expressing cancer who had failed standard therapies. Patients were monitored for toxicity and pharmacokinetics/dosimetry parameters.

Results: Imaging studies after 0.2 mCi/m2 (7.4 MBq/m2) show little redistribution out of the peritoneal cavity and no significant uptake in major organs. Peak blood level of the radiolabeled antibody, determined by decay corrected counts, was <23% injected dose at 63 hours; maximum blood radioactivity concentration was 6.3nCi/mL at 18 hours. Cumulative urinary excretion was ≤6% in 2.3 half-lives. The maximum external exposure rate immediately post-infusion at skin contact over the abdomen averaged 7.67 mR/h and dropped to 0.67 mR/h by 24 hours. The exposure rates at the other positions monitored (axilla, chest, and femur) decreased as a function of distance from the abdomen. The data points correlate closely with 212Pb physical decay (T1/2=10.6 hours). Follow-up >6 months showed no evidence of agent-related toxicity.

Conclusions: Pharmacokinetics and imaging after 0.2 mCi/m2 IP 212Pb-TCMC-trastuzumab in patients with HER-2-expressing malignancy showed minimal distribution outside the peritoneal cavity, ≤6% urinary excretion, and good tolerance.

Risk Perception, Worry, and Test Acceptance in Average-Risk Women Undergoing Ovarian Cancer Screening



abstract


Objective

We evaluated baseline knowledge of ovarian cancer risk and perceptions toward ovarian cancer screening (OCS) in women initiating the normal risk ovarian screening study (NROSS).

Study Design

Average-risk, postmenopausal women were enrolled between 2001 and 2011 as they entered the NROSS. Participants completed baseline surveys of risk perception, cancer worry (Cancer Worry Scale), anxiety (State-Trait Anxiety Inventory), health and well-being (SF-36), and acceptability of OCS.

Results

Of the 1242 women enrolled, 925 (74.5%) completed surveys. The respondents estimated a mean lifetime risk of ovarian cancer of 29.9%, much higher than the actual risk of 1.4% for women in the U.S. Only 2.8% of participants correctly estimated their risk, while 35.4% reported their lifetime risk to be ≥50%. Cancer worry was low, with a median CWS score of 7 out of 24. Anxiety was comparable to published norms for women in this age group, with median STAI-S and STAI-T scores of 30 and 29 out of 80, respectively. Overall, women reported good physical and mental well-being. In terms of OCS acceptability, 97.2% of respondents agreed, or strongly agreed, that “the benefits of screening outweigh the difficulties.” Very few women were reluctant to undergo OCS due to time constraints (1.1%), pain (2.0%), or embarrassment (1.9%).

Conclusions

Average-risk women undergoing OCS highly overestimated their risk of ovarian cancer. Despite this, participants reported low cancer worry and anxiety. The discrepancy between knowledge of and attitudes toward ovarian cancer risk highlights the need for educational efforts in this area.

Clinician characteristics, communication, and patient outcome in oncology: a systematic review - De Vries - 2013 - Psycho-Oncology - Wiley Online Library



abstract
 

Objective

The aim of this study was to review the literature on clinician characteristics influencing patient–clinician communication or patient outcome in oncology.

Methods

Studies investigating the association of clinician characteristics with quality of communication and with outcome for adult cancer patients were systematically searched in MEDLINE, PSYINFO, PUBMED, EMBASE, CINHAL, Web of Science and The Cochrane Library up to November 2012. We used the preferred reporting items for systematic reviews and meta-analyses statement to guide our review. Articles were extracted independently by two of the authors using predefined criteria.

Results

Twenty seven articles met the inclusion criteria. Clinician characteristics included a variety of sociodemographic, relational, and personal characteristics. A positive impact on quality of communication and/or patient outcome was reported for communication skills training, an external locus of control, empathy, a socioemotional approach, shared decision-making style, higher anxiety, and defensiveness. A negative impact was reported for increased level of fatigue and burnout and expression of worry. Professional experience of clinicians was not related to communication and/or to patient outcome, and divergent results were reported for clinician gender, age, stress, posture, and confidence or self-efficacy.

Conclusions

Various clinician characteristics have different effects on quality of communication and/or patient outcome. Research is needed to investigate the pathways leading to effective communication between clinicians and patients.

Metastatic Behavior of Upper Tract Urothelial Carcinoma After Radical Nephroureterectomy: Association with Primary Tumor Location



 Blogger's Note: this abstract does not indicate if Lynch Syndrome patients were included; of interest, especially, in light of the scarcity of research specific to UTUC (of the ureter/renal pelvis)

abstract

PURPOSE:

To investigate the site-specific pattern of disease recurrence and/or metastasis and the associated patient outcomes after radical nephroureterectomy (RNU) in upper tract urothelial carcinoma (UTUC).

METHODS:

A total of 733 patients with UTUC from a retrospective multi-institutional cohort were included, with a median follow-up of 34 months. Associated patient outcomes were analyzed by multivariate analysis. To evaluate the influence of primary tumor location, we divided it into four areas: renal pelvis, and upper, middle, and lower ureter.

RESULTS:

A total of 218 patients experienced disease recurrence, with the majority of relapses occurring within the first 3 years. Cumulative incidence rates of first disease recurrence at 1 and 3 years were 18.9 and 29.8 %, respectively. Of these patients, 38.5 % developed distant recurrence; 17.4 % experienced both local and distant recurrences; and 44.0 % developed isolated local recurrence. The predominant sites of distant metastasis were lung, liver, and bone. Multivariate analysis revealed that the prevalence of local recurrence and lung metastasis was significantly associated, with primary tumor location being independent of other clinicopathological variables. Lower/middle ureter tumors had a higher rate of local recurrence in the pelvic cavity, and renal pelvic tumors had a higher prevalence of distant relapse in the lungs. Similar results were obtained when rerunning the data set by excluding patients who received adjuvant chemotherapy (n = 131).

CONCLUSIONS:

This multi-institutional study provided a detailed picture of metastatic behavior after RNU, and primary tumor locations were associated with unique patterns of metastatic spread in UTUC patients.

    What Is Wrong With Discharges Against Medical Advice (and How to Fix Them)



    JAMA Network

    "It is estimated that as many as 2% of all US hospital discharges (approximately 500 000 per year) are designated as against medical advice1; that is, a patient chooses to leave the hospital before the treating physician recommends discharge. The risks to these patients are significant. Compared with patients discharged conventionally, readmission rates for patients discharged against medical advice are 20% to 40% higher, and their adjusted relative risk of 30-day mortality may be 10% higher.2 Furthermore, physicians and other health care staff report feeling distressed and powerless when patients choose suboptimal care, and disagreement over a discharge against medical advice can cause patient-physician and intrateam conflict.3

    Although these harms have been well described, the stigmatizing effect on patients of discharges against medical advice has rarely been examined. Compared with how the profession handles clinical disagreements in other settings (eg, outpatient), an “against medical advice” designation is an outdated concept unsupportive of patients. In this Viewpoint, starting from a core value of patient centeredness, we aim to highlight the problematic aspects of discharges against medical advice and suggest a new approach....

    "...Recent studies have highlighted problematic informed consent practices for discharges against medical advice by identifying that a majority of house officers and attending physicians mistakenly believe and inform patients that if they sign out against medical advice, their insurance may not pay for the hospitalization. In a cross-sectional survey of physicians conducted by Schaefer et al,5 85% of residents and 67% of attending physicians reported that they informed patients about denial of insurance payment so that patients would reconsider remaining in the hospital. These studies suggest that the use of misleading information in discharges against medical advice threatens to undermine a patient’s voluntary choice and insinuates that coercion is an acceptable and oft-repeated practice.....
     

    Reflecting on the methodological challenges of recruiting to a United Kingdom-wide, multi-centre, randomised controlled trial in gynaecology outpatient settings



    Trials open access

    Conclusions

    Our article reflects on the methodological challenges of recruiting to a multi-centre RCT in a UK gynaecology setting. Effective interventions included increasing the number of recruiting centres and providing collaborator incentives. Barriers to recruitment included fewer eligible women than anticipated, patient's preference to be allocated to the treatment group, lack of support staff, and variations in approval systems and GP referral procedures. To improve the evidence base on clinical trial recruitment, trialists need to publish their experiences and lessons learned. Future RCTs should evaluate, where possible, the effect of strategies designed to improve recruitment and retention.

    Cancer risk in systemic lupus: an updated international multi-centre cohort study [J Autoimmun. 2013] - PubMed - NCBI



    abstract

    OBJECTIVE:

    To update estimates of cancer risk in SLE relative to the general population.

    METHODS:

    A multisite international SLE cohort was linked with regional tumor registries. Standardized incidence ratios (SIRs) were calculated as the ratio of observed to expected cancers.

    RESULTS:

    Across 30 centres, 16,409 patients were observed for 121,283 (average 7.4) person-years. In total, 644 cancers occurred. Some cancers, notably hematologic malignancies, were substantially increased (SIR 3.02, 95% confidence interval, CI, 2.48, 3.63), particularly non-Hodgkin's lymphoma, NHL (SIR 4.39, 95% CI 3.46, 5.49) and leukemia. In addition, increased risks of cancer of the vulva (SIR 3.78, 95% CI 1.52, 7.78), lung (SIR 1.30, 95% CI 1.04, 1.60), thyroid (SIR 1.76, 95% CI 1.13, 2.61) and possibly liver (SIR 1.87, 95% CI 0.97, 3.27) were suggested. However, a decreased risk was estimated for breast (SIR 0.73, 95% CI 0.61-0.88), endometrial (SIR 0.44, 95% CI 0.23-0.77), and possibly ovarian cancers (0.64, 95% CI 0.34-1.10). The variability of comparative rates across different cancers meant that only a small increased risk was estimated across all cancers (SIR 1.14, 95% CI 1.05, 1.23).

    CONCLUSION:

    These data estimate only a small increased risk in SLE (versus the general population) for cancer over-all. However, there is clearly an increased risk of NHL, and cancers of the vulva, lung, thyroid, and possibly liver. It remains unclear to what extent the association with NHL is mediated by innate versus exogenous factors. Similarly, the etiology of the decreased breast, endometrial, and possibly ovarian cancer risk is uncertain, though investigations are ongoing.
     

    Investigating the clinical potential for 14-3-3 zeta protein to serve as a biomarker for epithelial ovarian cancer



    Journal of Ovarian Research open access

     Conclusions

    Determination of CA-125 and HE4 serum levels for the determination of the risk of ovarian malignancy algorithm (ROMA) represents a useful tool for the prediction of chemotherapy efficacy for EOC patients. However, levels of 14-3-3 zeta protein were not found to vary significantly as a consequence of treatment. Therefore we question if 14-3-3 zeta protein is a reliable biomarker, which correlates with the clinical behavior of EOC.

     Impact of family history of breast cancer on tumour characteristics, treatment, risk of second cancer and survival among men with breast cancer



    open access

    Introduction

    Breast cancer is the most common cancer among women in most countries, but it is rare in men, accounting for fewer than 1% of all breast cancer cases [1]. Rare germ-line mutations in BRCA1 and BRCA2 are thought to account for between 5% and 10% of all breast cancer cases in unselected populations. Male breast cancer (BC) is more strongly associated with the presence of an inherited BRCA2 mutation than with the presence of a BRCA1 mutation, and the lifetime risks of breast cancer for male mutation carriers are about 7% and 1%, respectively [2]. The scarcity of male BC has resulted in comparatively few epidemiological studies assessing the prevalence of a family history of breast and/or ovarian cancer among male BC patients, and its effect on male BC risks. Population-based studies reported that approximately 20% of men with breast cancer have a positive family history of the disease for at least one-degree relative [35]. Similar to that of breast cancer in women [6], an increased risk of breast cancer in men has been associated with a family history of breast cancer [5]. Several studies reported that male BC patients had a higher risk of developing a second primary cancer, but none of them assessed whether this risk was modified by a positive family history [711].
    In this study, we determined the prevalence of a positive family history of breast/ovary cancer among male BC patients. In addition, we evaluated the impact of family history, tumour characteristics and treatment on second cancer occurrence and overall survival.....

    "....Sites of second cancers were as follows: prostate (one case), lung (one case), tongue (two cases), stomach (one case) and contralateral breast (one case). The time interval between breast cancer diagnosis and date of second cancer varied from 24 months to 11.6 years....
     

    Accuracy of MDCT in the preoperative definition of Peritoneal Cancer Index (PCI) in patients with advanced ovarian cancer who underwent peritonectomy and hyperthermic intraperitoneal chemotherapy (HIPEC)



    Abstract

    PURPOSE:

    To evaluate the accuracy of MDCT in the preoperative definition of Peritoneal Cancer Index (PCI) in patients with advanced ovarian cancer who underwent a peritonectomy and hyperthermic intraperitoneal chemotherapy (HIPEC) after neoadjuvant chemotherapy to obtain a pre-surgery prognostic evaluation and a prediction of optimal cytoreduction surgery.

    MATERIALS AND METHODS:

    Pre-HIPEC CT examinations of 43 patients with advanced ovarian cancer after neoadjuvant chemotherapy were analyzed by two radiologists. The PCI was scored according to the Sugarbaker classification, based on lesion size and distribution. The results were compared with macroscopic and histologic data after peritonectomy and HIPEC. To evaluate the accuracy of MDCT to detect and localize peritoneal carcinomatosis, both patient-level and regional-level analyses were conducted. A correlation between PCI CT and histologic values for each patient was searched according to the PCI grading.

    RESULTS:

    Considering the patient-level analysis, CT shows a sensitivity, specificity, PPV, NPV, and an accuracy in detecting the peritoneal carcinomatosis of 100 %, 40 %, 93 % 100 %, and 93 %, respectively. Considering the regional level analysis, a sensitivity, specificity, PPV, NPV, and diagnostic accuracy of 72 %, 80 %, 66 %, 84 %, and 77 %, respectively were obtained for the correlation between CT and histology.

    CONCLUSION:

    Our results encourage the use of MDCT as the only technique sufficient to select patients with peritoneal carcinomatosis for cytoreductive surgery and HIPEC on the condition that a CT examination will be performed using a dedicated protocol optimized to detect minimal peritoneal disease and CT images will be analyzed by an experienced reader.
     

    High HMGA2 expression and high body mass index negatively affect the prognosis of patients with ovarian cancer



    abstract

    HMGA2 is a small, non-histone, chromatin-associated protein with a key role in tumorigenesis and adipogenesis. Indeed, HMGA2 overexpression has been frequently detected in several malignant neoplasms and inhibition of its expression prevents thyroid cell transformation. Moreover, HMGA2 null mice show a pigmy phenotype with a great reduction in fat tissue. To investigate whether HMGA2 expression correlates with clinico-pathological parameters and patient outcome, immunohistochemical analysis of HMGA2 expression was performed in ovarian cancer specimens from 117 patients. HMGA2 overexpression was found in 39% of the cases and, interestingly, positively correlated with the body mass index (BMI). Moreover, high BMI (≥ 25 kg/m(2) ) and high HMGA2 expression/BMI combined evaluation predicted shorter disease-free survival. High BMI (≥ 25 kg/m(2) ), high expression of HMGA2 and high HMGA2 expression/BMI combined evaluation predicted shorter overall survival. In multivariate analysis, the concomitant high expression of HMGA2 and high BMI (≥ 25 kg/m(2) ) was an independent prognostic factor. Finally, the BMI (≥ 25 kg/m(2) ) negatively correlated with the patient response to chemotherapy (P=0.039). Therefore, the data reported herein suggest that the combined evaluation of HMGA2 expression and obesity assessed through BMI can be considered a marker of poor prognosis in patients affected by ovarian carcinoma
