Giving VOICE to ovarian cancer survivors - authors: Carolyn Benivegna, Tracy Gorden, Sandi Pniauskas



Giving VOICE to ovarian cancer survivors ©
Survivors debate the issues

Authors:  Carolyn Benivegna*, Tracy Gorden*,  Sandi Pniauskas

*In Memorandum
 
During her research for a presentation concerning cancer patients’ voices in healthcare, Sandi Pniauskas took special notice of a paper published by an expert panel that included the following statement: "Patients or their representatives should not attend the Multidisciplinary Cancer Conference to ensure unbiased case review"  (Report dated June 2006, www.cancercare.on.ca/pdf/pebcmccf.pdf). 

While it would be imprudent to take this singular and remarkable quote as the “rule du jour,” this philosophy, and others similar to it, are prevalent in both private perception and in published literature on cancer survival/survivorship.

We can be thankful for more enlightened views, such as this example from the Journal of Health and Social Policy that, instead, celebrates the voices and contributions of (non-medical) health educators and activists:  

            The activists' efforts wrested control of “authoritative knowledge” that had once been the sole domain of the “experts” with advanced medical training. They used this knowledge to empower “average” people with medical information…to
promote self help and engage in civil disobedience, which led to changes in healthcare delivery (2006;21(3):55-69).

As ovarian cancer survivors we have learned much over the years.  Average, everyday citizens are taking active roles in their treatments and educating themselves about this deadly disease.  Yet in our view, and through the course of shedding light on this disease and the experiences of those living with it, it has become obvious that there is no such thing as an “average” survivor.

Ovarian cancer is not a new disease; in fact, it has been traced back as far as Egyptian times.  Advancements in research, education, awareness and access to care have gained some momentum, but they have also hit many roadblocks.  As ovarian cancer survivors  with international grassroots connections to, and support from, other survivors  we regularly discuss where this disease has been, and where it is going.  We now feel it is time to move these behind-the-scenes discussions to open forums. 

By being informed and proactive women with ovarian cancer, we have recognized the value and importance of conducting our own critical analysis.  Most importantly, we have learned to shift the focus onto the human elements and burdens of suffering that we experience each day in our communities.  

Creating a public forum for ovarian cancer survivors
As those living with this disease, we dream of what the future holds in terms of early detection, education, research, treatment and a cure. This dream has evolved in the form of organizing two ovarian cancer conferences for October 2007 -- one to be held in Novi, Michigan (US) and another in Toronto, Ontario (Canada) --  both entitled, “Survivors’ Debate: The Past Decade in Ovarian Cancer.” 

These public meetings are the result of a collaborative effort by proactive and knowledgeable ovarian cancer survivors with supporting oncology nurses. They will take place with the understanding that they will be fully inclusive – everyone is welcome -- but that the focus will remain on the experiences, needs and concerns of cancer patients and survivors, their families and friends.

The conferences will take place in two locations in two countries because our issues are the same: access to care, awareness, early detection, survival rates and genetics. The directive and focus of both conferences is to offer a place to exchange ideas honestly and openly without judgment or bias.

Patients need an environment where they feel encouraged to discuss the many difficulties they face.  Sometimes it is very difficult to find that space -- a place without fear of retribution, criticism or dismissive attitudes. Patient-to-patient discussion and counseling offers this environment. It allows for in-depth dialogue on a variety of topics that detail what strategies work for survivors and their families and what is not effective. Healthcare settings just do not currently lend themselves to foster the dialogue that is needed for survivors that this new forum provides.

However, the conferences will also focus on creating a public force to expedite change, which can only start with communication.  Born from need – an arena for discussion for ovarian cancer survivors by survivors -- the “Survivors’ Debate” has taken form. 

But while the conferences are about patients speaking for themselves they are not speaking by themselves. With this new forum for dialogue, debate and discussion, we can highlight the detailed knowledge and expertise of our international ovarian cancer community with almost a decade of experience behind us, and explain why, as a community, we work. But we will also be able to explore the variety of reasons why what is needed by survivors and their friends and families is not currently being translated into caregiving.

Our ovarian cancer survivor connections and bonds have formed through the years by enduring extreme challenges and personal losses. The only bias we have as survivors is the bias to endure and to survive to the best of our abilities, not only as individuals but, importantly, as a community. To be very blunt, previously this has included much silent suffering.

It is long past due that we take our real issues into a public forum and encourage everyone to participate. We plan to make some long overdue noise at these debates about ovarian cancer, and we envision that these two scheduled events are only the beginning of a completely new trend in ovarian cancer activism.

Side-bar:
Ovarian cancer
Ovarian cancer is a serious and under-recognized threat to women's health which kills more women than all of the gynecologic cancers combined.  The lifetime risk of contracting ovarian cancer is one in seventy~.  Ovarian cancer is very treatable when caught early, but the vast majority of cases are not diagnosed until too late, which means that while it is not as common as some other cancers, it remains a woman’s cancer with a poor survival rate.

Unfortunately, an early detection test still remains elusive and contrary to public perception, the PAP test is not a screening test for ovarian cancer. Efforts to diagnose ovarian cancer is through a combination of: tumor marker test (called the CA125), a bimanual pelvic/rectal exam and transvaginal ultrasound. Actual confirmation of the diagnosis of ovarian cancer is confirmed with surgery and pathology reports (eg. Laboratory tests on tissue/s specimen). When ovarian cancer is caught before it has spread beyond the ovaries 80-90%~ of women will survive five years. When diagnosed after the disease has spread, the chance of five-year survival drops to approximately 20-30%~ or less.

Signs and symptoms
Symptoms of ovarian cancer are nonspecific and mimic those of many other more common conditions, including other cancers.  However, as a result of the original work in 1999 of Cindy Melancon, RN (who died of ovarian cancer in 2003) and Dr Barbara Goff, it has now been established that both early and advanced stage ovarian cancer do have  recognizable symptoms. This debate continues -semantics.

A consensus expert panel convened earlier this year concluded that the following four symptoms are much more likely to occur in women with ovarian cancer than women in the general population:
* Bloating;
* Pelvic or abdominal pain;
* Difficulty eating or feeling full quickly;
* Urinary symptoms (urgency or frequency).

Several other symptoms have been commonly reported by women with ovarian cancer, as well; these symptoms include fatigue, indigestion, back pain, pain with intercourse, constipation and menstrual irregularities.  A woman should consult with a health care professional if any of these symptoms persist or feel abnormal.

What you can do
* Understand your family history (e.g., ovarian, breast, colorectal cancer (organs/cancers of the gastrointestinal tract),endometrial cancers);
*  Educate yourself and understand ovarian cancer as it relates to your specific diagnosis;
*  Communicate your concerns with your healthcare professional;
*  Recognize and support other ovarian cancer women/families in your community;
* learn and appreciate the lived experience of your fellow survivors;
*  Join a social networking support group and/or face-to-face support group;
*  Join a cancer organization or a program in your community and/or hospital. 

Ovarian cancer is not a silent disease – speak up and speak out - it is only a silent disease when 'we' are not listening

PLoS Medicine: Being the Ghost in the Machine: A Medical Ghostwriter's Personal View



"Introduction

Ethical concerns about medical ghostwriting have been directed primarily at “guest” authors and the pharmaceutical companies that pay them. One voice that is largely missing is that of the ghostwriters themselves who, after all, create the documents that are in the ethical and legal crosshairs. Without them, one could argue, there can be no fraud, because it is they who create the fraudulent product.
For almost 11 years, I worked as a medical writer, creating a variety of pieces including the occasional ghostwritten article. For the most part, I never saw the finished paper, nor did I care to. This article describes what I did, why I did it, why I stopped doing it, and what I think might be done about the problem of fraud in authorship......"cont'd

"The ICMJE guidelines will always be a work in progress, but the adjustments proposed here have the potential to end the self-concealment and authorial misrepresentations that mar industry's contributions to the literature. Furthermore, they have the potential to help industry achieve the enhanced respect its beneficial contributions to medicine deserve. Industry publications will always have a commercial valence alongside their scientific and medical content: this should henceforth be truthfully displayed, and no longer downplayed or concealed."

abstract: Lymphadenectomy in ovarian cancer: standard of care or unne... : Current Opinion in Oncology



Abstract

Purpose of review: The clinical significance of lymphadenectomy in ovarian cancer is controversial. In early ovarian cancer (EOC), it is the extent of the procedure that is the main focus of debate. In advanced disease [advanced ovarian cancer (AOC)], the issue is whether or not lymphadenectomy independently impacts survival. This review summarizes the current standard of care as it relates to the role of lymphadenectomy in ovarian cancer.
Recent findings: Lymphadenectomy in EOC is a diagnostic procedure in as much as it is an integral and mandatory part of a complete surgical staging. The required extent of the procedure, however, remains uncertain. It has been suggested that at least 10 nodes from different, predefined retroperitoneal sites should be the minimum number removed. Lymphadenectomy in AOC is of potential therapeutic value. The only published randomized clinical trial (RCT) showed no overall survival benefit after radical/systematic lymphadenectomy, although there was an impact on 6-month disease-free survival. Conversely, retrospective studies, a meta-analysis and a re-analysis of three RCTs in AOC do suggest an overall survival benefit for radical/systematic lymphadenectomy.
Summary: This review concludes with the recommendation that lymphadenectomy in EOC is a mandatory part of surgical staging and that a minimum of 10 nodes should be harvested from different retroperitoneal sites. In AOC, lymphadenectomy can be considered when intraperitoneal cytoreduction has been complete or when there are bulky nodes.

 "...

Findings

91 patients were enrolled (65 with ovarian cancer and 26 breast cancer) and 90 were treated between July 8, 2008, and Sept 24, 2009. In the ovarian cancer cohorts, 64 patients received treatment. 63 patients had target lesions and therefore were evaluable for objective response as per RECIST. In these patients, confirmed objective responses were seen in seven (41%; 95% CI 22—64) of 17 patients with BRCA1 or BRCA2 mutations and 11 (24%; 14—38) of 46 without mutations. No confirmed objective responses were reported in patients with breast cancer. The most common adverse events were fatigue (45 [70%] of patients with ovarian cancer, 13 [50%] of patients with breast cancer), nausea (42 [66%] and 16 [62%]), vomiting (25 [39%] and nine [35%]), and decreased appetite (23 [36%] and seven [27%])...."

press release: Mayo Clinic receives FDA approval for ovarian and breast cancer vaccines



ROCHESTER, Minn. — Mayo Clinic has received investigational new drug approval (http://www.fda.gov/BiologicsBloodVaccines/DevelopmentApprovalProcess/InvestigationalNewDrugINDorDeviceExemptionIDEProcess/default.htm) from the Food and Drug Administration (http://www.fda.gov/) for two new cancer vaccines that mobilize the body's defense mechanisms to destroy malignant cells. The vaccines are among the first aimed at preventing cancer recurrence. The approval clears the way for Phase I clinical trials with women treated for ovarian or breast cancer.

VIDEO ALERT: Additional audio and video resources, including comments by Dr. Keith Knutson are available at the Mayo Clinic News Blog (http://dev.newsblog.mayoclinic.org/2011/08/17/mayo-clinic-studies-cancer-vaccines/).
"People who've had cancer are at high risk for relapse, and later rounds of treatment can become more difficult," says Mayo Clinic immunologist Keith Knutson, Ph.D., (http://mayoresearch.mayo.edu/mayo/research/staff/Knutson_KL.cfm) who developed the vaccines with colleagues at Mayo Clinic. While most cancer vaccines to date have been developed to fight patients' tumors, Knutson's group is interested in immunizing patients immediately after therapy, when they're healthy, to protect against relapse.

One new vaccine targets a protein that exists in abundance in breast and ovarian cancer cells. Containing fragments of the folate receptor alpha protein, the vaccine teaches the body's immune system to detect and eliminate diseased cells. Because the protein is typical of nearly all breast and ovarian tumors, the vaccine is the first that may be applicable to the majority of patients, instead of sub-populations with distinct types of cancer.
"I'm quite optimistic that if we can combine early detection, effective conventional therapies and vaccination, we can reduce recurrence and long-term morbidity associated with breast and ovarian cancer," Knutson says. Ultimately, the vaccine may be useful as a preventive strategy for all women.

The second vaccine to receive FDA approval is designed to be administered after breast cancer patients receive conventional chemotherapy. It targets the highly aggressive Her2/neu molecule, a protein that promotes the growth of cancer cells.
"One of the greatest fears for women who've been treated for breast cancer is that the cancer will return," Knutson says. "Our hope is that the vaccine will boost the cancer-fighting capabilities of the immune system and will be a leg up on this aggressive cancer after conventional treatment is complete."

Clinical Oncology News - The Concept of ‘Unrealistic Optimism’ In Early-Phase Trials (Markman) - Aug issue



"Oncologists may not be fully aware of a relatively new term introduced by ethicists to describe certain patients who agree to participate in early-phase cancer clinical trials. Some researchers believe that these individuals express unrealistic optimism, which apparently means that despite understanding the limited statistical probability of experiencing clinical benefit from a particular management plan, they have a strong belief regarding their own favorable outcome.1 These researchers apparently feel such optimism poses a serious problem, with one member of this community of scholars being quoted as remarking, “We just need to realize that not all optimism is ethically benign.”2...............For it would appear that those who support the concept of unrealistic optimism, or its sister term therapeutic misconception, have not kept up with the oncology literature dealing with early-phase clinical trials........cont'd

Rush researchers discover antibody that may help detect ovarian cancer in earliest stages - press release (mesothelin antibodies)



Note: in research

".....In the study at Rush, researchers tested for mesothelin antibodies in the bloodstream of 109 women who were infertile, 28 women diagnosed with ovarian cancer, 24 women with benign ovarian tumors or cysts, and 152 healthy women. Infertility was due to endometriosis, ovulatory dysfunction or premature ovarian failure or was unexplained.
Significant levels of mesothelin antibodies were found in women with premature ovarian failure, ovulatory dysfunction and unexplained infertility, as well as in women with ovarian cancer, although not in women with endometriosis and not in healthy women or women with benign disease. Endometriosis is generally associated with a different kind of ovarian carcinoma (blogger's note - cell types: endometrioid/clear cell)  than other types of infertility, which may explain why mesothelin antibodies were not found in these cases.
Why the presence of mesothelin antibodies in the bloodstream should be linked with ovarian cancer is not clear.
"It has been hypothesized that an autoimmune response precedes or somehow contributes to the development and progression of malignant tumors," Luborsky said. "We think that antibodies may arise in response to very early abnormal changes in ovarian tissue that may or may not progress to malignancy, depending on additional triggering events. Or, alternatively, antibodies may bind to normal cells in the ovary, causing dysfunction and leading to infertility -- and, in a subpopulation of women, to the development of ovarian cancer.".....cont'd

Summary

The hallmarks of cancer comprise six biological capabilities acquired during the multistep development of human tumors. The hallmarks constitute an organizing principle for rationalizing the complexities of neoplastic disease. They include sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis. Underlying these hallmarks are genome instability, which generates the genetic diversity that expedites their acquisition, and inflammation, which fosters multiple hallmark functions. Conceptual progress in the last decade has added two emerging hallmarks of potential generality to this list—reprogramming of energy metabolism and evading immune destruction. In addition to cancer cells, tumors exhibit another dimension of complexity: they contain a repertoire of recruited, ostensibly normal cells that contribute to the acquisition of hallmark traits by creating the “tumor microenvironment.” Recognition of the widespread applicability of these concepts will increasingly affect the development of new means to treat human cancer

About ENMD-2076
ENMD-2076 is an orally-active, Aurora A/angiogenic kinase inhibitor with a unique kinase selectivity profile and multiple mechanisms of action. ENMD-2076 has been shown to inhibit a distinct profile of angiogenic tyrosine kinase targets in addition to the Aurora A kinase. Aurora kinases are key regulators of mitosis (cell division), and are often over-expressed in human cancers. ENMD-2076 also targets the VEGFR, Flt-3 and FGFR3 kinases which have been shown to play important roles in the pathology of several cancers. ENMD-2076 has shown promising activity in Phase 1 clinical trials in solid tumor cancers, leukemia, and multiple myeloma. ENMD-2076 is currently in a Phase 2 trial for ovarian cancer, and preclinical and clinical activities are ongoing in assessing the compound's applicability for other forms of cancer.

abstract: Circulating free DNA and p53 antibodies in plasma of patients with ovarian epithelial cancers (serous/mucinous)



Blogger's Note: the connection between KRAS mutations/mucinous may be due to GI (particularly colorectal cancer eg. common denominator = KRAS mutation/mucinous cell type), see also mucinous article - to be posted subsequent to this item

BACKGROUND:

This study was conducted in order to evaluate the significance of circulating free DNA (CFDNA), blood plasma p53 antibodies (p53-Ab) and mutations of KRAS gene in the prognosis of ovarian epithelial cancers.

PATIENTS AND METHODS:

A total of 126 patients were included in this study. KRAS mutations and CFDNA were detected by means of the PCR-restriction fragment length polymorphism (PCR-RFLP) and enriched by the PCR-RFLP method. Enzyme-linked immunosorbent assay was used to analyze plasma p53-Ab.

RESULTS:

KRAS mutations were detected in 27 (21.4%) of examined tumors. The frequency of KRAS mutations was especially high in mucinous cancers (P < 0.001). CFDNA and p53-Ab were frequently detected in patients with serous cancers in high grade (P < 0.001). The overall survival rate was significantly lower for patients with serous tumors and CFDNA and p53-Ab-positive than negative tumors (P = 0.022 and P < 0.001, respectively). In mucinous ovarian cancer, a worse overall survival was correlated with the KRAS mutations (P = 0.03).

CONCLUSIONS:

The results of the present study suggested that a presence of KRAS mutations in mucinous ovarian cancer and CFDNA and p53-Ab in serous tumors was correlated with the highest risk of cancer progression.

abstract: Mucinous tumor of low malignant potential ("borderline" or "atypical proliferative" tumor) of the ovary: a study of 171 cases with the asses



Abstract

Mucinous tumors of the ovary are a continuing source of controversy in the field of gynecologic pathology. We examined a series of 171 intestinal-type mucinous tumors of low malignant potential ("borderline" or "atypical proliferative" tumors) to clarify the clinical significance of intraepithelial carcinoma (IECA) and microinvasion (area ≤ 10 mm²). The diagnosis of IECA was based on the presence of marked nuclear atypia (grade 3). Stromal microinvasion was classified as low grade and high grade (with nuclear grade 3). IECA was observed in 67 of 171 cases (39.2%). Microinvasion was identified in 31 (18.1%) cases, low grade in 22 (12.9%) cases, and high grade in 9 (5.3%) cases. Follow-up status was known in 144 cases and tumor recurrence was observed in 6 patients (4.2%). The risk factors for recurrence included International Federation of Gynecology and Obstetrics stage ≥ IC (P=0.002), microinvasion (P=0.013), age less than 45 years (P=0.032), and IECA (P=0.042). The amount of IECA ≥ 10% was also associated with the risk of recurrence (P=0.007). Among tumors with microinvasion, there was no significant association between the clinicopathologic variables and recurrence. When considering tumors with stage ≥ IC, tumor recurrence was significantly associated with IECA ≥ 10% (P=0.031) and age less than 45 years (P=0.047). It is important that mucinous tumors of low malignant potential should be staged and be optimally sampled for pathologic examination to document the status of the external surface or peritoneal involvement and to identify the worst degree of epithelial proliferation. Tumor stage ≥ IC, IECA ≥ 10%, microinvasion, and age less than 45 years were the features that were associated with tumor recurrence.
The study results also support the use of nuclear grade 3 as the sole criterion of IECA.

Cancers | Free Full-Text | Assessment of the Evolution of Cancer Treatment Therapies



Note: numerous references to ovarian cancer

Conclusions
This review has tried to summarize the history and evolution of the most common types of cancer
treatments available today, but also new therapies under study in the last years. In addition to surgery,
chemotherapy, radiation therapy, hyperthermia, photodynamic therapy or immunotherapy, new
therapies are now at different stages of development trying to decrease drug toxicity in health tissues
and increase efficacy by targeting tumor angiogenesis, by exploring cell and gene therapy, or by using
new nanostructures for diagnosis or therapeutic purposes. Nanotechnology is offering new products,
which either used alone, due to their intrinsic properties, or in combination with other biomolecules
(anti-tumoral drugs, folic acid, albumin, antibodies, aptamers) could be used to target cancer cells.
However, the history tells us that the fight against cancer is not an easy task. Many types of cancers
are able to resist to conventional therapies, and different combinations of drugs and therapies
(e.g., surgery together with radiotherapy and chemotherapy) are usually the only way to destroy
tumoral cells. This may be also true for the new therapies arriving now to the clinic. Much more
studies are required but these new ways of treatment are opening doors to hope for many patients
waiting for a successful therapy

abstract: Cochrane review - Optimal primary surgical treatment for advanced epithelial ovarian cancer



Abstract

BACKGROUND:

Ovarian cancer is the sixth most common cancer among women. In addition to diagnosis and staging, primary surgery is performed to achieve optimal cytoreduction (surgical efforts aimed at removing the bulk of the tumour) as the amount of residual tumour is one of the most important prognostic factors for survival of women with epithelial ovarian cancer. An optimal outcome of cytoreductive surgery remains a subject of controversy to many practising gynae-oncologists. The Gynaecologic Oncology group (GOG) currently defines 'optimal' as having residual tumour nodules each measuring 1 cm or less in maximum diameter, with complete cytoreduction (microscopic disease) being the ideal surgical outcome. Although the size of residual tumour masses after surgery has been shown to be an important prognostic factor for advanced ovarian cancer, it is unclear whether it is the surgical procedure that is directly responsible for the superior outcome that is associated with less residual disease.

OBJECTIVES:

To evaluate the effectiveness and safety of optimal primary cytoreductive surgery for women with surgically staged advanced epithelial ovarian cancer (stages III and IV).To assess the impact of various residual tumour sizes, over a range between zero and 2 cm, on overall survival.

MAIN RESULTS:

There were no RCTs or prospective non-RCTs identified that were designed to evaluate the effectiveness of surgery when performed as a primary procedure in advanced stage ovarian cancer.We found 11 retrospective studies that included a multivariate analysis that met our inclusion criteria. Analyses showed the prognostic importance of complete cytoreduction, where the residual disease was microscopic that is no visible disease, as overall (OS) and progression-free survival (PFS) were significantly prolonged in these groups of women. PFS was not reported in all of the studies but was sufficiently documented to allow firm conclusions to be drawn.When we compared suboptimal (> 1 cm) versus optimal (< 1 cm) cytoreduction the survival estimates were attenuated but remained statistically significant in favour of the lower volume disease group There was no significant difference in OS and only a borderline difference in PFS when residual disease of > 2 cm and < 2 cm were compared (hazard ratio (HR) 1.65, 95% CI 0.82 to 3.31; and HR 1.27, 95% CI 1.00 to 1.61, P = 0.05 for OS and PFS respectively).There was a high risk of bias due to the retrospective nature of these studies where, despite statistical adjustment for important prognostic factors, selection bias was still likely to be of particular concern. Adverse events, quality of life (QoL) and cost-effectiveness were not reported by treatment arm or to a satisfactory level in any of the studies.

AUTHORS' CONCLUSIONS:

During primary surgery for advanced stage epithelial ovarian cancer all attempts should be made to achieve complete cytoreduction. When this is not achievable, the surgical goal should be optimal (< 1 cm) residual disease. Due to the high risk of bias in the current evidence, randomised controlled trials should be performed to determine whether it is the surgical intervention or patient-related and disease-related factors that are associated with the improved survival in these groups of women. The findings of this review that women with residual disease < 1 cm still do better than women with residual disease > 1 cm should prompt the surgical community to retain this category and consider re-defining it as 'near optimal' cytoreduction, reserving the term 'suboptimal' cytoreduction to cases where the residual disease is > 1 cm (optimal/near optimal/suboptimal instead of complete/optimal/suboptima

Genesis of the LIFE Before Death project lay in remarks from WHO. “The project co-producer Mike Hill and I read a 2009 WHO statement saying that 600 million people worldwide were going to suffer in their lifetime from untreated pain due to a lack of access to medicinal opiates”, explains Australian documentary maker Sue Collins. “We found that a very alarming statistic”, she added. Here are three more alarming statistics: more than 5 billion people worldwide have no access to essential pain medicines; this year 3·6 million people will die with untreated severe pain from cancer and AIDS; and 99·9% of these deaths will be in low-income and middle-income countries.

The predicted truncation from a (ovarian) cancer-associated variant of the MSH2 initiation codon alters activity of the MSH2-MSH6 mismatch repair complex



Abstract

Lynch syndrome (LS) is caused by germline mutations in DNA mismatch repair (MMR) genes. MMR recognizes and repairs DNA mismatches and small insertion/deletion loops. Carriers of MMR gene variants have a high risk of developing colorectal, endometrial, ovarian, and other extracolonic carcinomas. We report on an ovarian cancer patient who carries a germline MSH2 c.1A>C variant which alters the translation initiation codon. Mutations affecting the MSH2 start codon have been described previously for LS-related malignancies. However, the patients often lack a clear family history indicative of LS and their tumors often fail to display microsatellite instability, a hallmark feature of LS...."(technical)

Prognostic Role of Vitamin D Status and Efficacy of Vitamin D Supplementation in Cancer Patients: A Systematic Review - the Oncologist



Abstract  

Background. Whether or not hypovitaminosis D can influence the prognosis of cancer patients and whether or not vitamin D (vitD) supplementation improves outcome remain controversial.


Conclusion. Hypovitaminosis D seems to be associated with a worse prognosis in some cancers, but vitD supplementation failed to demonstrate a benefit in prostate cancer patients. The currently available evidence is insufficient to recommend vitD supplementation in cancer patients in clinical practice.

EvidenceUpdates - Strategies to identify the lynch syndrome among patients with colorectal cancer: a cost-effectiveness analysis. (focus on women/risk reduction strategies) - abstract



"..... At current rates of germline testing, screening, and prophylactic surgery, the strategies reduced deaths from colorectal cancer by 7% to 42% and deaths from endometrial and ovarian cancer by 1% to 6%....."  

CONCLUSION: Widespread colorectal tumor testing to identify families with the Lynch syndrome could yield substantial benefits at acceptable costs, particularly for women with a mutation associated with the Lynch syndrome who begin regular screening and have risk-reducing surgery. The cost-effectiveness of such testing depends on the participation rate among relatives at risk for the Lynch syndrome.

abstract: Comparing diagnostic delay in cancer: a cross-sectional study in three European countries with primary care-led health care systems (UK, Netherlands, Sweden)



Conclusions. A large-scale study comparing cancer delays in European countries and based on primary care-held records is feasible but would require supplementary sources of data in order to maximize information on demographic variables, the cancer stage at diagnosis and treatment details. Such a large-scale study is timely and desirable since our findings suggest systematic differences in the way cancer is managed in the three countries.

Continuing Medical Education

Abstract

Method
Selective review of the literature.


Results
COCs suppress gonadotropin secretion and thereby inhibit follicular maturation and ovulation. Their correct use is associated with 0.3 pregnancies per 100 women per year, their typical use, with 1 pregnancy per 100 women per year (Pearl index). COCs have effects on the cardiovascular and hemostatic systems as well as on lipid and carbohydrate metabolism. When given in the presence of specific risk factors, they significantly increase the likelihood of cardiovascular disease and thromboembolism. Women with persistent human papilloma virus (HPV) infection who take COCs are at increased risk of developing invasive cervical cancer. On the other hand, COCs lower the cumulative incidence of endometrial and ovarian cancer by 30% to 50%, and that of colorectal cancer by 20% to 30%. Other malignancies seem to be unaffected by COC use.


Conclusion
As long as personal and familial risk factors are carefully considered, COCs constitute a safe, reversible, and well-tolerated method of contraception.

MicroRNA Processing and Binding Site Polymorphisms Are Not Replicated in the Ovarian Cancer Association Consortium



Background: Single nucleotide polymorphisms (SNP) in microRNA-related genes have been associated with epithelial ovarian cancer (EOC) risk in two reports, yet associated alleles may be inconsistent across studies.

Results:
After adjustment for European ancestry, no overall association was observed between any of the analyzed SNPs and EOC risk.

Conclusions: Common variants in these evaluated genes do not seem to be strongly associated with EOC risk.

Impact: This analysis suggests earlier associations between EOC risk and SNPs in these genes may have been chance findings, possibly confounded by population admixture. To more adequately evaluate the relationship between genetic variants and cancer risk, large sample sizes are needed, adjustment for population stratification should be carried out, and use of imputed SNP data should be considered

Markman M.

Cancer Treatment Centers of America, Eastern Regional Medical Center, Philadelphia, PA, USA.

Abstract

Pegylated liposomal doxorubicin (PLD) has become a major component in the routine management of epithelial ovarian cancer. The drug is frequently employed as a single agent in the platinum-resistant setting, and recently reported data reveal the superiority of the combination of PLD plus carboplatin, compared with the platinum drug plus paclitaxel, in delaying the time to disease progression in women with recurrent (potentially platinum-sensitive) disease. Current research efforts involving PLD in ovarian cancer are focusing on adding novel targeted drugs to this cytotoxic agent. The utility of such approaches in the platinum-resistant population, compared with the sequential administration of single agents active in this setting, remains to be determined.

Frank words about breast screening - Open Medicine - Analysis and Comment



"......As recently observed in the New England Journal of Medicine, we should “work to prevent vested interests from being granted the loudest voices in health care.”2 The vested interests in what has been termed “the mammography wars”2 are clearly those in the imaging industry, those involved directly in screening programs, and even those in the not-for-profit sector, whose fundraising capacity is enhanced by a public committed to fighting breast cancer.
It is reasonable for women to choose to be screened, but only if they are completely informed about the probability of benefit versus the probability of harm. For 2000 women aged 40–49 who undergo screening for 10 years, the benefit is much smaller in terms of avoiding death from breast cancer than is the harm arising from over-diagnosis and unnecessary treatment for breast cancer, to say nothing of the increased rates of mastectomy associated with screening.22,23 These issues are not widely known to the general public. After over 20 years of involvement in the screening controversy I can only conclude that this is information few want to hear and many want to suppress."
