Official Title: “A Cancer
Research UK Phase I First in Man Study of the Novel AGC Kinase Inhibitor
AT13148 Given Orally in Patients With Advanced Solid Tumours.”
The purpose of this first clinical study of the noval multiple
AGC kinase inhibitor, AT13148, is to identify the recommended dose for
future studies in cancer patients by exploring the safety and maximum
tolerated dose and biological effects in patients with advanced solid
tumours.
- Study Type: Interventional
- Study Design: Masking: Open Label, Primary Purpose: Treatment
- Study Primary Completion Date: October 2015
Detailed Clinical Trial Description
AT13148 is a new drug which looks promising in laboratory
studies. We now wish to find out if it will be useful in treating
patients with cancer. AT13148 is a type of drug called a protein kinase
inhibitor. It blocks several different chemical messengers (enzymes)
called AGC kinase proteins. These chemical messengers are part of the
signaling process within cells which can make cells produce chemicals
that trigger and control cell growth and cell death. In some types of
cancer these chemical messengers are 'switched on' or 'switched off'
permanently due to changes in the genes of cells called "gene mutations"
leading to uncontrolled cancer cell growth. AT13148 targets multiple
protein kinases from three families of kinases unlike many of the other
protein kinase inhibitors currently being tested which target just one
or two kinases. This may mean that it will work better and in a wider
group of cancer patients. Patients will not be selected to take part
based on having these gene mutations for this first trial because we
want to learn more about which mutations are most important but this
would be the hope for future trials. The patient population anticipated
to benefit from this drug includes certain types of breast, prostate and
ovarian cancer which more commonly have these gene mutations.

Nutrition and physical activity guidelines for cancer survivors - CA: A Cancer Journal for Clinicians
".... After receiving a diagnosis of cancer, survivors soon find there are few clear answers to even the simplest questions, such as: Should I change what I eat? Should I exercise more? Should I gain or lose weight? Should I take dietary supplements? Cancer survivors receive a wide range of advice from many sources about foods they should eat, foods they should avoid, how they should exercise, and what types of supplements they should take, if any. Unfortunately, this advice is often inconsistent and not supported by data...."
Ovarian Cancer
Ovarian cancer is the leading cause of death from gynecologic malignancies in the United States.4
Symptoms tend be nonspecific, making early detection difficult.
Consequently, most ovarian cancers are diagnosed at an advanced stage
when the prognosis is poor, with an overall 10-year survival rate of
39%.4 The role of lifestyle factors in ovarian cancer prognosis is largely unknown.138, 242 To our knowledge, only 3 studies139, 140, 243
have evaluated the role of dietary factors in ovarian cancer survival.
These 3 studies were based on prospective follow-up of the cases
participating in case-control studies and evaluated the association
between prediagnosis dietary intake and mortality outcomes. One study,
conducted in China, focused on the role of green tea and reported that a
higher frequency and quantity of green tea intake after diagnosis was
associated with better survival.243 The other 2 studies, conducted in Australia140 and the United States,139
suggested that prediagnosis dietary intake may influence the survival
experience of patients with ovarian cancer. Both studies tended to
support the association of fruit and vegetable consumption with better
survival. Dairy food intake was associated with poorer survival in one
of the studies,140 while in the other, only milk consumption and not total dairy food consumption was inversely associated with survival.139 Meat consumption was associated with better survival in the Australian study,140 and with lower survival in the study conducted in the United States.139
While these studies controlled for most relevant covariates, they did
not include treatment information. In addition, these studies did not
evaluate dietary intake after diagnosis. However, they do suggest that
dietary intake may influence ovarian cancer survival and warrant further
research in this area.
Only one study,
also following cases in a case-control study for mortality, has
evaluated the role of physical activity in ovarian cancer survival.244
Prediagnosis physical activity was ascertained as hours per week for 3
life periods (childhood, between ages 18-30 years, and in recent years).
The study also evaluated the role of changes in physical activity over
time. There was not much indication of an association with survival for
any of these variables, except for physical activity at aged 18 to 30
years, which seemed to be associated with better survival for women with
early stage ovarian cancer and with worse survival for women with an
advanced stage of disease at diagnosis.245
The
relationship between excess weight and ovarian cancer survival has been
evaluated by relatively few studies. Obesity may affect ovarian cancer
survival by having a negative impact on optimal surgical and cytotoxic
treatment and increasing the likelihood of postoperative complications.246 Overall, the literature evaluating the association between weight/BMI and ovarian cancer survival is limited and inconclusive.76, 242
Cohort studies evaluating the role of prediagnosis obesity obtained at
baseline on ovarian cancer mortality have generally found elevated
ovarian cancer mortality among obese women.234, 247
Other studies evaluating the role of prediagnosis BMI on ovarian cancer
survival by following cases in a case-control study or clinical trial
(using baseline data) have offered conflicting results.242
The role of postdiagnosis body size and weight changes on ovarian
cancer survival is largely unknown. Only one study has reported on
weight changes during chemotherapy and ovarian cancer survival and found
that, among patients with advanced ovarian cancer, weight loss during
chemotherapy was associated with worse prognosis; however, it is
difficult to determine whether this weight loss was involuntary or
intentional.248
In
summary, while the current evidence is limited and inconclusive, it
points to a possible role of dietary factors, physical activity, and
body size and weight changes in modulating ovarian cancer survival, and
for physical activity in improving the quality of life among ovarian
cancer survivors. Further studies are needed before public health
recommendations can be made.

paywalled: Coffee and tea consumption and the risk of ovarian cancer: a prospective cohort study and updated meta-analysis
Blogger's Note/Opinion: as per abstract, to date and studies over decades, have not found a link between coffee/tea/ovarian cancer risk - so, the question is this: how many more studies will it take to finally put this issue to rest? Unless there are novel (new) findings then we need to move forward.
Coffee and tea consumption and the risk of ovarian cancer: a prospective cohort study and updated meta-analysis
Abstract
Background: In 2007 the World Cancer Research Fund Report concluded that there was limited and inconsistent evidence for an effect of
coffee and tea consumption on the risk of epithelial ovarian cancer (EOC).
Objective: In the European Prospective Investigation into Cancer and Nutrition (EPIC), we aimed to investigate whether coffee intakes,
tea intakes, or both are associated with the risk of EOC.
Design: All women participating in the EPIC (n
= 330,849) were included in this study. Data on coffee and tea
consumption were collected through validated food-frequency
questionnaires at baseline. HRs and 95% CIs were
estimated by using Cox proportional hazards models. Furthermore, we
performed
an updated meta-analysis of all previous
prospective studies until April 2011 by comparing the highest and lowest
coffee-
and tea-consumption categories as well as by using
dose-response random-effects meta-regression analyses.
Results: During a median
follow-up of 11.7 y, 1244 women developed EOC. No association was
observed between the risk of EOC and coffee
consumption [HR: 1.05 (95% CI: 0.75, 1.46) for the
top quintile compared with no intake] or tea consumption [HR: 1.07 (95%
CI: 0.78, 1.45) for the top quintile compared with
no intake]. This lack of association between coffee and tea intake and
EOC risk was confirmed by the results of our
meta-analysis.
Conclusion: Epidemiologic studies do not provide sufficient evidence to support an association between coffee and tea consumption and
risk of ovarian cancer.

Systematic review of progesterone use by midlife and menopausal women: Publication year: 2012
Source: Maturitas
Progesterone treatment for menopausal symptoms is still controversial. Progesterone levels fall during menopause transition, therefore some menopausal women may benefit from progesterone therapy. A systematic review was conducted of studies published from 2001 reporting on progesterone use to treat symptoms associated with menopause or postmenopausal women. Fourteen data bases were searched using the search terms progesterone, menopause, aged, female and human; exclusions were breast cancer, animal and contraception. Thirteen studies were selected for inclusion (11 clinical trials, 1 cohort study and 1 qualitative study), evaluating progesterone effects on menopausal symptoms, bone, sleep, skin, cognition, plasma lipids and plaque progression. Most studies were of low methodological quality (GRADE low or very low). Progesterone improved vasomotor symptoms and sleep quality, with minimal risk. Large studies designed to identify confounders, such as hormone levels, menopausal status and metabolism are required to understand the place of progesterone in clinical practice.

Study confirms overuse of blood transfusions during surgery
"Citing the lack of clear guidelines for ordering blood transfusions during surgery, Johns Hopkins researchers say a new study confirms there is still wide variation in the use of transfusions and frequent use of transfused blood in patients who don't need it.
The resulting overuse of blood is problematic, the researchers say, because blood is a scarce and expensive resource and because recent studies have shown that surgical patients do no better, and may do worse, if given transfusions prematurely or unnecessarily. "Transfusion is not as safe as people think," says Steven M. Frank, M.D., leader of the study described in the journal Anesthesiology.....

Role of HE4, CA72.4, and CA125 in monitoring ovarian cancer.
Abstract
The aim of this study was to investigate the role of biomarkers CA125, HE4, and CA72.4 at diagnosis and throughout the follow-up in patients with epithelial ovarian cancer (EOC). Thirty-nine patients with EOC were deemed eligible, and 20 were followed up. CA125, HE4, and CA72.4 serum levels were determined for all patients at initial diagnosis of EOC. Among these patients, the number of cases with an elevated level of each individual marker was CA125 77 %, HE4 85 %, and CA72.4 72 %. A statistically significant difference was observed between the level of HE4 when compared to CA72.4 (p < 0.02). In the follow-up phase, we observed tumor marker levels fluctuating according to response to chemotherapy. When combining two out of the three biomarkers together, we observed increased values of CA125 and CA72.4 in 55 % of the patients, increased values of CA125 and HE4 in 65 % of the patients, and finally increased HE4 and CA72.4 in 75 % of the patients. A statistically significant difference was observed when combining HE4 and CA72.4, but not CA125 and CA 72.4 (p < 0.002). In conclusion, our study demonstrates that the association of three biomarkers CA125, HE4, and CA72.4 provides a valuable contribution in the follow-up of EOC patients.open access: Cancer, Fertility Preservation, and Future Pregnancy: A Comprehensive Review

Conclusions
Given the relatively high incidence of cancer in reproductive age women and improvements in 5-year survival, an increasing number of women are presenting for discussion of fertility preservation and pregnancy after cancer treatment. The ASCO published recommendations in 2006 on fertility preservation in cancer patients. These guidelines state that oncologists should address the possibility of infertility with cancer patients and be prepared to discuss possible fertility preservation options or refer the patient to a reproductive specialist. Part of the difficulty in counseling patients regarding the risk of infertility and/or subsequent pregnancy complications is that the risks are dependent on several factors. These risks include the dose and duration of treatment, other risk factors for infertility, the age of the patient, and the patient’s baseline ovarian reserve at the time of initiation of treatment.

paywalled: Predisposition gene identification in common cancers by exome sequencing: insights from familial breast cancer.
Breast Cancer Res Treat. 2012 Apr 18;
Abstract
The genetic component of breast cancer predisposition remains largely unexplained. Candidate gene case-control resequencing has identified predisposition genes characterised by rare, protein truncating mutations that confer moderate risks of disease. In theory, exome sequencing should yield additional genes of this class. Here, we explore the feasibility and design considerations of this approach. We performed exome sequencing in 50 individuals with familial breast cancer, applying frequency and protein function filters to identify variants most likely to be pathogenic. We identified 867,378 variants that passed the call quality filters of which 1,296 variants passed the frequency and protein truncation filters. The median number of validated, rare, protein truncating variants was 10 in individuals with, and without, mutations in known genes. The functional candidacy of mutated genes was similar in both groups. Without prior knowledge, the known genes would not have been recognisable as breast cancer predisposition genes. Everyone carries multiple rare mutations that are plausibly related to disease. Exome sequencing in common conditions will therefore require intelligent sample and variant prioritisation strategies in large case-control studies to deliver robust genetic evidence of disease association.

paywalled: Breast-feeding and risk of epithelial ovarian cancer (clear cell/endometrioid)
Breast-feeding and risk of epithelial ovarian cancer
AbstractPURPOSE:
Evidence suggests that breast-feeding may decrease the risk of epithelial ovarian cancer but it is not clear whether there is a relationship with duration of breast-feeding, patterns of breast-feeding, or particular histological subtypes of ovarian cancer. We sought to investigate these issues in detail.METHODS:
Data from participants in a population-based study of ovarian cancer in western Washington State, USA (2002-2007) who had had at least one birth (881 cases and 1,345 controls) were used to assess relations between patterns of breast-feeding and ovarian cancer. Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI).RESULTS:
Women who ever breast-fed had a 22 % reduction in risk of ovarian cancer compared with those who never breast-fed (OR = 0.78, 95% CI 0.64-0.96) and risk reduction appeared greater with longer durations of feeding per child breast-fed (OR = 0.56, 95% CI 0.32-0.98 for 18 months average duration breast-feeding versus none). Introduction of supplementary feeds did not substantially alter these effects. The overall risk reduction appeared greatest for the endometrioid and clear cell subtypes (OR per month of average breast-feeding per child breast-fed = 0.944, 95% CI 0.903-0.987).CONCLUSIONS:
Among women who have had the opportunity to breast-feed, ever breast-feeding and increasing durations of episodes of breast-feeding for each breast-fed child are associated with a decrease in the risk of ovarian cancer independent of numbers of births, which may be strongest for the endometrioid subtype.

Knowledge of Reproductive System Cancers, Their Treatments and Side Effects
Abstract
We
explored, via an online questionnaire, knowledge of breast and
reproductive system cancers in patients and non-patients
who access the internet for information on these diseases.
We compared that knowledge to the attention the diseases have received
in medical research and on the Internet. Data were collected
from 690 respondents (37 % male, 63 % female) about their knowledge
of prevalence, lethality, treatments and side effects of
testicular, prostate, breast, uterine, cervical and ovarian cancers.
Most males, but only half of the female participants, were
patients themselves. Although participants showed better knowledge
of cancers specific to their own sex, both sexes felt
familiar with breast cancer and less aware of other cancers. Women were
as aware as men of side effects of treatments for male
reproductive cancers. Sex differences in awareness appear to reflect
different attitudes towards illness, bias toward females as
caregivers, and the disproportionate media attention given to
breast cancer.

Cell–cell and cell–matrix dynamics in intraperitonealcancer metastasis
Abstract/pdf full text:
IntroductionIntraperitoneal dissemination is the primary metastatic route
of ovarian cancers. It is also a common progression for
gastrointestinal malignancies including colorectal, gastric,
and pancreatic cancers.....
~~~~~~~~~~~~~~~~~
The peritoneal metastatic route of cancer dissemination
is shared by cancers of the ovary and gastrointestinal
tract. Once initiated, peritoneal metastasis typically proceeds
rapidly in a feed-forward manner. Several factors
contribute to this efficient progression. In peritoneal metastasis,
cancer cells exfoliate into the peritoneal fluid and
spread locally, transported by peritoneal fluid. Inflammatory
cytokines released by tumor and immune cells compromise
the protective, anti-adhesive mesothelial cell layer that lines
the peritoneal cavity, exposing the underlying extracellular
matrix to which cancer cells readily attach. The peritoneum
is further rendered receptive to metastatic implantation and
growth by myofibroblastic cell behaviors also stimulated by
inflammatory cytokines. Individual cancer cells suspended
in peritoneal fluid can aggregate to form multicellular spheroids.

CONCLUSIONS:
Our finding that
relatives of serrated polyposis patients are at significantly increased
risk of colorectal and pancreatic cancer adds to the accumulating
evidence that serrated polyposis has an inherited component.
~~~~~~~~~~~~~~~~~
Johns Hopkins Colon Cancer Center:
Individuals are diagnosed with hyperplastic polyposis when they have multiple hyperplastic polyps, usually greater than 20 polyps. The number of polyps ranges anywhere from 6 to greater than 100, though most individuals with hyperplastic polyposis have between 40 and 100 polyps. A diagnosis of Hyperplastic polyposis may also made in individuals who present with fewer than 20 hyperplastic polyps, but whose polyps are larger, often greater than 2 centimeters. Individuals may also be diagnosed with multiple serrated adenomas or a mix of both serrated adenomas and hyperplastic polyps. Hyperplastic polyposis is usually diagnosed in individuals in their 40’s to 60’s, though it has been reported in individuals as young as 11 years old. Individuals with hyperplastic polyposis are at an increased risk for developing colorectal cancer, so routine screening is extremely important. Although the genetic basis for FAP, HNPCC, Peutz-Jeghers, MYH-Associated Polyposis, and juvenile polyposis has been identified, hyperplastic polyposis has not yet been explained. Hyperplastic polyposis is suspected to have a familial basis and reports have shown that is inheritable in 5% of cases, though the exact mechanism of inheritance has not been identified.

Supplements and cancer prevention: A cautionary tale - Journal of National Cancer Institute - press release
Supplements and cancer prevention: A cautionary tale
Public release date: 25-Apr-2012
Journal of the National Cancer Institute
Supplements and cancer prevention: A cautionary tale
Government regulators and the scientific community should work to ensure that they give clear guidance to the public about dietary supplements and cancer risk, according to a commentary published April 25 in the Journal of the National Cancer Institute.Evidence from animal, in vitro and observational studies has suggested that taking dietary supplements may lower cancer risk. However, the small number of randomized controlled studies, the gold standard in evidence-based medicine, has not confirmed this—and some studies have actually shown that supplements may increase cancer risk. Still, the supplement industry is booming, with estimated annual sales at $30 billion in the U.S.
To examine the potential role of dietary supplements and cancer risk, Maria Elena Martinez, Ph.D., of the University of California San Diego Moores Cancer Center and colleagues, looked at observational studies of several supplements, including anti-oxidants, folic acid, vitamin D, and calcium. Several observational studies found that diets high in fruits and vegetables were associated with lower risk of certain cancers, including respiratory and gastrointestinal. Specifically, with respect to anti-oxidant supplements, the authors found that: "The importance of oxidative stress for carcinogenesis does not establish that the administration of supplemental antioxidants will protect against the carcinogenesis that oxidative stress may induce." Furthermore, they write, "Supplementation by exogenous antioxidants may well be a two-edged sword; these compounds could, in vivo, serve as pro-oxidants or interfere with any of a number of protective processes such as apoptosis induction." Indeed, several antioxidant trials the researchers examined reported increased cancer risks with supplementation. They looked at trials with supplements using folic acid, vitamin D and calcium, among other compounds.
The researchers caution against taking dietary supplements for
cancer prevention, adding that many expert committees and organizations
have concluded that nutritional supplements have little or no benefit in
cancer prevention. They say that more randomized control
trials—spanning many years instead of just a few—are needed to verify
the effect of nutritional supplementation in cancer risk.

open access: Oxaliplatin-related thrombocytopenia
Oxaliplatin-related thrombocytopenia
Abstract/Full Text:
Oxaliplatin is a third generation platinum
compound that inhibits DNA synthesis, mainly through intrastrandal
cross-links
in DNA. Most of the experience with the clinical
use of this drug is derived from colorectal cancer but it is also used
in
other tumor types such as ovary, breast, liver and
non-Hodgkin's lymphoma. Thrombocytopenia is a frequent toxicity seen
during
oxaliplatin treatment, occurring at any grade in up
to 70 % of patients and leading to delays or even discontinuation of
the
chemotherapy. Although myelossupression is
recognized as the main cause of oxaliplatin-related thrombocytopenia,
new mechanisms
for this side-effect have emerged, including
splenic sequestration of platelets related to oxaliplatin-induced liver
damage
and immune thrombocytopenia. These new
pathophysiology pathways have different clinical presentations and
evolution and may
need specific therapeutic maneuvers. This article
attempts to review this topic and provides useful clinical information
for
the management of oxaliplatin-related
thrombocytopenia.
conclusions
Oxaliplatin-related thrombocytopenia can
prevent the administration of the optimal dose and schedule of this
important chemotherapy
agent and limit its benefits in the adjuvant or
metastatic setting. Mild to moderate bone marrow suppression is the main
cause
of thrombocytopenia during and after treatment with
oxaliplatin. In this setting, patients present thrombocytopenia
concomitant
to anemia and neutropenia usually 1–2 weeks after
treatment. Therapeutic approaches will include dose delays or reduction
and consideration of platelet-stimulating agents.
However, novel mechanisms of oxaliplatin-related thrombocytopenia should
promptly be recognized by physicians and include an
immune-dependent mechanism, as well as portal hypertension related to
sinusoidal injury yielding splenic sequestration of
platelets.
OIIT usually presents a sudden and
isolated drop in platelet counts minutes to hours after oxaliplatin
administration, leading
to acute hemorrhagic events. Female patients with
advanced CRC and prior oxaliplatin exposure are more likely to develop
this
consequence. Prompt immunological testing
documenting oxaliplatin-mediated platelet destruction leads to
definitive diagnosis.
Platelets counts will improve after discontinuation
of treatment and transfusions may be necessary during the acute phase.
Other measures such as corticoid or immunoglobulin
administration are controversial and patients with documented OIIT
should
not be rechallenged with oxaliplatin.
Hepatic sinusoidal injury is a well-known
complication of oxaliplatin treatment and can lead to portal
hypertension and hypersplenism.
Thrombocytopenia in this setting demonstrates a
different natural history, with moderate but prolonged reductions in
platelet
counts. Splenomegaly and other complications of
portal hypertension are recognized in these patients. Platelet recovery
is
slow and usually takes 2–3 years to be complete
after treatment discontinuation. When a fast platelet recovery is
wanted,
splenic embolization might be considered as a
therapeutic measure.
An improvement in the recognition of

LAPTM4B Polymorphisms is Associated with Ovarian Cancer Susceptibility and Its Prognosis:
Objective
Lysosome-associated protein transmembrane 4 beta (LAPTM4B) is an important novel gene associated with the proliferation and differentiation of cells. Recent studies have shown that it was overexpressed in many cancer tissues. This study investigated the association between different LAPTM4B polymorphisms and the susceptibility and prognosis of ovarian cancer.
Methods
A case–control study was performed in 282 patients with ovarian cancer and 365 control subjects. Genomic DNA was extracted from peripheral blood lymphocytes in all participants. LAPTM4B genotypes were determined using polymerase chain reaction.
Results
There was a significantly higher LAPTM4B*2 allele frequency in ovarian cancer cases than controls (P < 0.05). Using the LAPTM4B*1/1 genotype as the reference, we found that the LAPTM4B*1/2 and LAPTM4B*2/2 genotypes were positively associated with ovarian cancer.

Oncology Information on the Internet
Abstract:
Owing to new developments in Internet
technologies, the amount of available oncology information is growing.
Both patients
and caregivers are increasingly using the Internet
to obtain medical information. However, while it is easy to provide
information,
ensuring its quality is always a concern. Thus,
many instruments for evaluating the quality of health information have
been
created, each with its own advantages and
disadvantages. The increasing importance of online search engines such
as Google
warrants the examination of the correlation between
their rankings and medical quality. The Internet also mediates the
exchange
of information from one individual to another.
Mailing lists of advocate groups and social networking sites help spread
information
to patients and caregivers. While text messages are
still the main medium of communication, audio and video messages are
also
increasing rapidly, accelerating the communication
on the Internet. Future health information developments on the Internet
include merging patients' personal information on
the Internet with their traditional health records and facilitating the
interaction among patients, caregivers and
health-care providers. Through these developments, the Internet is
expected to
strengthen the mutually beneficial relationships
among all stakeholders in the field of medicine.

Clinical development of new formulations of cytotoxics in solid tumors
Purpose of review:
To discuss the clinical development
of new formulations of old cytotoxic agents and highlight the value of
adopting this strategy.
Recent findings:
Several drugs are currently in
clinical development with high potential in improving clinical outcomes
compared with their older counterparts. We emphasize on the results of
four of these agents, each belonging to a known group of cytotoxics
namely amrubicin, EndoTAG-1, pralatrexate and NKTR-102. Each has shown
promising results that have the potential in addressing some limitations
that have been observed with the ‘earlier generation’ agents.
Summary:
Improvement in drug development strategies
and the appreciation of the mechanisms of action and resistance of the
cytotoxic agents currently available in the clinic open the door for
developing agents that have the potential of improving clinical outcomes
with better safety profiles. It is important to adopt innovative
clinical trials designs integrating molecular markers in early clinical
development in order to identify the subgroups of patients who would
derive the maximal benefit of these novel agents.

Targeting the DNA damage response in oncology: past, present and future perspectives
Abstract
Purpose of review:
The success of poly(ADP-ribose)
polymerase inhibition in BRCA1 or BRCA2 deficient tumors as an
anticancer strategy provided proof-of-concept for a synthetic lethality
approach in oncology. There is therefore now active interest in
expanding this approach to include other agents targeting the DNA damage
response (DDR). We review lessons learnt from the development of
inhibitors against DNA damage response mechanisms and envision the
future of DNA repair inhibition in oncology.

Abstract
Purpose of review:
Targeting the tumor vasculature is
an attractive approach for cancer therapy. Vascular disrupting agents
(VDAs) are compounds that directly target tumor blood vessels and create
central tumor necrosis. The current review aims to summarize the
clinical development (i.e. safety and efficacy) of this class of
compounds.
Recent findings:
VDAs have demonstrated signs of
clinical activity in different tumor types [e.g. anaplastic thyroid
carcinoma (ATC), nonsmall cell lung carcinoma (NSCLC), ovarian cancer,
sarcoma]. However, the lack of predictive biomarkers to identify
patients with a high probability of response to VDAs, places this class
of compounds at a high risk of failure. This has recently been
exemplified by several negative phase II/III trials in NSCLC, ATC, and
castration-refractory metastatic prostate cancer.
Summary:
VDAs represent a unique class of anticancer
compounds. Their clinical development is hampered by cardiovascular,
neurological toxicities as single agent and by hematological toxicity in
combination with chemotherapy. Molecular predictors of their efficacy
are crucial for further development. As single agent, only few objective
responses have been observed in a variety of solid tumors. However,
VDAs have failed to demonstrate a survival advantage in several phase
II/III trials especially in combination with chemotherapy.

Increased risk of neoplasm in appendicitis treated with interval appendectomy: single-institution experience and literature
Abstract
Appendicitis is a common diagnosis encountered by the acute care surgeon. Management of complicated appendicitis is controversial and often involves initial nonoperative therapy with interval appendectomy. This study reviews single-institutional experience with management of complicated appendicitis with interval appendectomy and addresses an unusually high occurrence of incidental appendiceal malignancies observed with a review of relevant literature. A retrospective review of all diagnoses of appendicitis was performed over 5 years at a tertiary care center. Patient demographics, time to surgery, operative technique, pathologic diagnosis, and clinical outcomes were examined. Three hundred fifteen patients were diagnosed with acute appendicitis. Of these, 24 (7.6%) were deemed complicated and did not undergo immediate appendectomy, and 18 ultimately underwent appendectomy at our institution and were included in analysis. There were no statistical demographic or symptomatic differences between the immediate and interval appendectomy patients. Ninety-nine per cent of the immediate appendectomy patients were treated laparoscopically; 78 per cent of the interval group underwent attempted laparoscopic treatment with 56 per cent completed without conversion to open (P < 0.01). Neoplasms were discovered in 1 per cent of the acute appendectomy group and 28 per cent of the interval appendectomy group (P < 0.0001). Two of the three neoplasms in the acute group were carcinoid, whereas three of the five neoplasms in the interval group were adenocarcinoma. Surgeons should consider appendiceal or colonic neoplasms in cases of complicated appendicitis when nonoperative management is considered. This is most important in patients older than 40 years, in those who forego interval appendectomy, or in those who could be lost to follow-up.

A
small proportion of breast cancers metastasize within the peritoneal
cavity. With increasing breast cancer incidence rates, gynaecologists
and oncologists will encounter such women more frequently. Most women
with intraperitoneal breast cancer are premenopausal. Although data are
limited and are likely to be subject to selection bias, the median
survival of women undergoing resection appears superior to those not
undergoing surgery. Furthermore, survival is broadly similar to that for
women undergoing advanced ovarian cancer surgery, particularly when
tumour debulking is optimal. Obtaining data via randomised trials is
unlikely to be feasible and therefore we recommend prospective data
collection via the establishment of an international intraperitoneal
breast cancer patient registry. For individual women where survival is
anticipated to be more than a few months, we suggest considering
referral to a gynaecological oncology team for discussion of surgical
options.

XGEVA® (denosumab) sales were $153 million in the first quarter of 2012, an increase of 14 percent over the fourth quarter of 2011, reflecting increased segment share as well as overall segment growth.
Prolia® (denosumab) sales were $88 million in the first quarter of 2012, an increase of 9 percent over the fourth quarter of 2011, reflecting continued global growth.
Combined Neulasta® (pegfilgrastim) and NEUPOGEN® (Filgrastim) sales increased 9 percent to $1,344 million in the first quarter of 2012 versus $1,232 million in the first quarter of 2011. Combined U.S. Neulasta and NEUPOGEN sales increased 13 percent to $1,053 million in the first quarter of 2012 versus $930 million in the first quarter of 2011, driven primarily by an increase in the average net sales price and, to a lesser extent, an increase in Neulasta unit demand. Combined Neulasta and NEUPOGEN international sales decreased 4 percent to $291 million in the first quarter of 2012 versus $302 million in the first quarter of 2011, due primarily to a decrease in the average net sales price. A mid single-digit percentage point increase in Neulasta unit demand was offset by a decline in NEUPOGEN units due primarily to biosimilar competition.
Enbrel® (etanercept) sales increased 7 percent to $938 million in the first quarter of 2012 versus $875 million in the first quarter 2011, driven primarily by an increase in the average net sales price. ENBREL remains the segment share leader in both the rheumatology and dermatology segments.
Aranesp® (darbepoetin alfa) sales decreased 11 percent to $518 million in the first quarter of 2012 versus $580 million in the first quarter of 2011. U.S. Aranesp sales decreased 19 percent to $202 million in the first quarter of 2012 versus $250 million in the first quarter of 2011, due primarily to a decline in unit demand, offset partially by a mid single-digit percentage point increase in the average net sales price. The unit decline reflects segment contraction resulting from changes to the product label and reimbursement environment that occurred during 2011. International Aranesp sales decreased 4 percent to $316 million in the first quarter of 2012 versus $330 million in the first quarter of 2011, due primarily to a decrease in the average net sales price.
EPOGEN® (epoetin alfa) sales decreased 17 percent to $446 million in the first quarter of 2012 versus $535 million in the first quarter of 2011, reflecting the impact of changes to the label and reimbursement. The decline was comprised of an approximately 30 percent decrease in unit demand driven by a reduction in dose utilization, offset partially by reductions in customer discounts as part of new provider contracts that became effective Jan. 1, 2012.
On a sequential basis, EPOGEN sales decreased 8 percent, comprised of an approximately 20 percent decrease in unit demand driven by the timing of end-user purchases at the end of 2011 and a reduction in dose utilization. These decreases were offset partially by reductions in customer discounts as part of new provider contracts.
Sales of our other, growth-phase products increased 22 percent to $399 million in the first quarter 2012 versus $327 million in the first quarter of 2011. Sales of Sensipar®/Mimpara® (cinacalcet) increased 17 percent to $219 million in the first quarter of 2012 versus $187 million in the first quarter of 2011.

Campaigners call for Scottish Government to act over needless ovarian cancer deaths - The Daily Record
Campaigners call for Scottish Government to act over needless ovarian cancer deaths - The Daily Record
"New research shows woeful symptom awareness among women in Scotland with only one per cent of those surveyed being very confident of noticing a symptom. Across the UK the figure was just three per cent.
And, of the GPs surveyed in Scotland, 86 per cent agreed that updates to Scottish clinical guidelines would support them to diagnose ovarian cancer more effectively.
Now campaigners have called on the Scottish Government top spearhead a national campaign to increase symptom awareness.
In April 2011, the National Institute for Health and Clinical Excellence (NICE) published the first official guidance to GPs in England and Wales about the symptoms, diagnosis and early treatments for ovarian cancer.
The Target Ovarian Cancer Pathfinder Study 2012 found 68 per cent of a UK-wide representative sample of 402 GPs was aware of the NICE guidance.
However, GPs in Scotland will have to wait until later this year for updated guidance from the Scottish Intercollegiate Guidelines Network......"

Thailandepsins are new small molecule class I HDAC inhibitors with potentcytotoxic activity in ovarian cancer cells: a preclinical study of epigenetic ovarian cancer therapy
Abstract
Background
New treatment strategies are emerging to target DNA damage response pathways in ovarian cancer. Our group has previously shown that the class I biased HDAC inhibitor romidepsin (FK228) induces DNA damage response and has potent cytotoxic effects in ovarian cancer cells. Here, we investigated newly discovered HDAC inhibitors, thailandepsin A (TDP-A) and thailandepsin B (TDP-B), to determine the effects on cell viability, apoptosis and DNA damage response in ovarian cancer cells......

Folate binding protein (FBP) is highly over-expressed in breast, ovarian and endometrial cancers
and is the source of immunogenic peptides (E39) that can stimulate
cytotoxic T lymphocytes (CTL) to recognize and destroy FBP-expressing cancer
cells in the laboratory. The purpose of this study is to test whether a
peptide-based vaccine consisting of the E39 peptide mixed with the
FDA-approved immunoadjuvant granulocyte macrophage colony-stimulating
factor (GM-CSF) is safe and effective at inducing an in vivo
peptide-specific immune response. Furthermore, the investigators intend
to determine the best dose of the vaccine to utilize to produce this
immunity most efficiently. The investigators will determine whether
immunity to FBP will prevent clinical recurrence. Additionally, the
investigators will compare these results with results from a trial
utilizing the E75 peptide (from the HER2/neu protein) in ovarian and endometrial cancer patients in preparation for studying a combination vaccine.

Patients
with extensive and bulky disease are often those whose initial surgery
is delayed after 3 or 4 cycles of neo-adjuvant chemotherapy.
In that case, there is,
indeed, some concern to administer bevacizumab during the chemotherapy
surrounding the interval debulking surgery due to the long half life
(14- 21 days) of this monoclonal antibody and the interference of anti
angiogenic agents with wound healing.
Vargatef® (Nintedanib)
might offer a better alternative to bevacizumab in the neo-adjuvant
setting. Vargatef® (Nintedanib) has a much shorter half-life of 7 to 19
hours. Preliminary experience in cancer did
not show a trend for increased incidence of fistula or bowel
perforation. For more details please refer to the investigator drug
brochure for Vargatef® (Nintedanib).
This trial will compare
progression-free survival and surgical complications of 188 patients
with FIGO stage IIIC/IV treated in first line with either neo-adjuvant
chemotherapy (carboplatin & paclitaxel) and interval debulking
surgery or the same treatment + Vargatef® (Nintedanib).

PET/CT scanning guided intensity-modulated radiotherapy in treatment of recurrent ovarian cancer.
PET/CT scanning guided intensity-modulated radiotherapy in treatment of recurrent ovarian cancer.
Abstract
OBJECTIVE: This study was undertaken to evaluate the clinical contribution of positron emission tomography using (18)F-fluorodeoxyglucose and integrated computer tomography (FDG-PET/CT) guided intensity-modulated radiotherapy (IMRT) for treatment of recurrent ovarian cancer.
MATERIALS AND METHODS: Fifty-eight patients with recurrent ovarian cancer from 2003 to 2008 were retrospectively studied. In these patients, 28 received PET/CT guided IMRT (PET/CT-IMRT group), and 30 received CT guided IMRT (CT-IMRT group). Treatment plans, tumor response, toxicities and survival were evaluated.
RESULTS: Changes in GTV delineation were found in 10 (35.7%) patients based on PET-CT information compared with CT data, due to the incorporation of additional lymph node metastases and extension of the metastasis tumor. PET/CT guided IMRT improved tumor response compared to CT-IMRT group (CR: 64.3% vs. 46.7%, P=0.021; PR: 25.0% vs. 13.3%, P=0.036). The 3-year overall survival was significantly higher in the PET-CT/IMRT group than control (34.1% vs. 13.2%, P=0.014).
CONCLUSIONS: PET/CT guided IMRT in recurrent ovarian cancer patients improved the delineation of GTV and reduce the likelihood of geographic misses and therefore improve the clinical outcome.

Blogger's Note/Opinion: the actual paper published in the CMAJ is not an open access publication which defies logic given the subject matter- see below for CMAJ and following is the 'public' press release; as mentioned, but focused on institutional control, the other issue is the matter of who/what/control is included in a patient charter (see prior CMAJ publications on this issue); note also that 'professional Patient Navigators' in hospitals play in role, however, this is not an independent process/role; the role of an ombudsun has been a matter of great discussion over decades

Canadian provinces need to adopt a patient charter of rights
Canadian provinces should adopt a patient charter of rights with independent enforcement as part of the move to patient-centred care, argues an analysis article in CMAJ (Canadian Medical Association Journal).A properly designed patient charter of rights (standards set by whom?) can help patients resolve concerns and complaints easily and cost-effectively, through an independent ombudsman or commissioner. An effective patient charter contains clearly articulated patient rights — many of which are already provided in law but scattered in different places — such as patients' rights to access their health records, to privacy and to informed consent.
Many countries such as New Zealand, Norway, Finland, England, Israel have patient charters. Quebec is the only jurisdiction in Canada with a charter. Alberta has recently enacted one, but it lacks the critical feature of independent enforcement.
Health professionals may have concerns that patient charters will increase lawsuits or disciplinary actions, but evidence shows that "patient charters with dedicated complaints processes enable matters to be resolved at an early stage by informal means, averting the need for litigation or formal disciplinary proceedings," write Colleen Flood and Kathryn May, Faculty of Law, University of Toronto. In New Zealand, for example, formal disciplinary actions against providers have plummeted because a patient commissioner mediates patient complaints.
An independent health ombudsman can help spur overall improvement in the system by issuing recommendations or reports on system problems. Overseas experience suggests that despite having no formal powers to implement change such recommendations can nonetheless be a powerful force for change.
"A patient charter of rights should achieve greater clarity and awareness of the nature and extent of patients' rights; if well-designed, it should also help drive improvements in the quality and timeliness of care, improve the overall accountability of members of the health care system and reduce costly litigation," the authors conclude. "However, experience shows that it is easy for a patient charter to be a toothless tiger — that is, a mechanism to merely talk about improving the patient experience and reforming the health care system."
