- Adverse effect search for term
- An adverse event for which the causal relation between the drug/intervention and the event is at least a reasonable possibility. The term ‘adverse effect’ applies to all interventions, while ‘adverse drug reaction’ (ADR) is used only with drugs. In the case of drugs an adverse effect tends to be seen from the point of view of the drug and an adverse reaction is seen from the point of view of the patient.See also: Adverse event, Side effect Also called: Adverse reaction
- Baseline characteristics search for term
- Values of demographic, clinical and other variables collected for each participant at the beginning of a trial, before the intervention is administered.
- Causal effect search for term
- An association between two characteristics that can be demonstrated to be due to cause and effect, i.e. a change in one causes the change in the other. Causality can be demonstrated by experimental studies such as controlled trials (for example, that an experimental intervention causes a reduction in mortality). However, causality can often not be determined from an observational study.
Molecular Test Aids in Identifying Cancers of Unknown Origin - Medscape (pathology/molecular diagnostic test - 15 different cancer types...)
".....The identity of most tumors can be determined "with confidence" by clinicians with histologic, clinical, and radiographic findings, say the study authors, led by James P. Grenert, MD, from the Department of Pathology at UCSF. "However, when tumors are poorly differentiated or metastatic with no clear primary, identifying the tissue of origin is difficult," they write.
Immunohistochemical stains may or may not be helpful in identifying the tumor origin. Molecular testing of tumors is an additional means of characterizing these tumors, the authors say.
TOO is the only molecular diagnostic test for cancer tissue of origin cleared by the US Food and Drug Association, the manufacturer notes. It is limited to identifying 15 types of tumor tissues: bladder, breast, colorectal, gastric, testicular germ cell, kidney, hepatocellular, nonsmall-cell lung, non-Hodgkin's lymphoma, melanoma, ovarian, pancreas, prostate, thyroid, and sarcoma. These 15 tumor types represent 90% of all cancers, the company points out....."cont'd
The study was funded in part by a grant from Pathwork Diagnostics.
Clin Chim Acta. 2011;412:1462–1464. Abstract
(adverse event) abstract: Inadvertent cystotomy at laparoscopic hysterectomy – Sydney West Advanced Pelvic Surgery (SWAPS)
Inadvertent cystotomy is a recognised complication at hysterectomy. The rate in the SWAPS unit is comparable to that of other published series. Overall, there has been a decline in the rate of bladder injury, which appears attributable to more experience gained with an acquisition of increased skill levels and improved techniques.
Overall, 177 consecutive patients (pts) were analyzed. The median age at first diagnosis was 55 years (range, 23-83 years). The complete tumor resection rate was 44.6%. Predictive factors that correlated with an adverse surgical outcome in terms of residual tumor were ascites <500 ml (Odds ratio, OR=0.3; 95% Confidence interval, CI=0.1-0.8 p<0.05), tumor involvement of the small bowel (OR=0.22; 95% CI=0.07-0.71 p<0.05), tumor spread in the upper abdomen (OR=0.33; 95% CI=0.1-0.9 p<0.05) and platinum resistance (OR=0.1, 95% CI=0.06-0.5 p<0.01).
Serous tumor histology (OR=5.8) appeared to have a protective effect. Age and initial FIGO stage were of no predictive significance.
Platinum-sensitive patients without ascites, no intestinal tumor involvement, tumor restricted to middle and lower abdomen, and of serous papillary histology have significantly higher complete tumor resection rates. Prospective studies are warranted to evaluate the predictive value of these factors."
Note: worth paying attention to the stats
Cost-effectiveness analyses typically express their principal results as incremental cost-effectiveness ratios (ICERs).
ICERs are useful in making decisions for allocation of resources at a population level, but typical ICER measures have shortcomings when used for individual decisions.
For the same ICER, the cost-effectiveness may vary among individuals because not everyone assigns the same priorities to specific outcomes, shares the same attitudes toward risk, or faces the same distribution of expected outcomes.
ICER information can be enhanced by providing additional metrics that individualize cost-effectiveness analyses.
These metrics include the per person net benefit and cost, subgroup ICER estimates for observed measured sources of heterogeneity, and distributions of outcomes and costs for unknown or unmeasured sources of heterogeneity.

Risk for CRC in Lynch Syndrome May Be Lower Than We Thought: Prevalence of Alterations in DNA Mismatch Repair Genes in Patients With Young-Onset Colorectal Cancer - Medscape Oncology
"Clearly, as we develop more accurate estimates of risks associated with specific mutations, personalized screening methods and intervals will need to be further clarified among those with LS. Although it appears that the overall risk for CRC among those with LS may be lower than previously thought, there are likely to be specific mutations that confer a higher risk and require more intensive screening protocols."
European Journal of Cancer : Primary versus secondary cytoreduction for epithelial ovarian cancer: A paired analysis of tumour pattern and surgical outcome
Conclusions Secondary cytoreduction due to EOC appears to be associated with significantly lower optimal tumour debulking rates compared to primary setting, since the disease tends to recur in patterns less accessible to complete resection such as gastrointestinal serosa, mesentery and upper abdomen. By maximal surgical effort, tumour residuals significantly correlate between primary and secondary cytoreduction. No other predictors of surgical outcome or tumour-pattern could be identified.
Poly(ADP-Ribose) Polymerase Inhibition Synergizes with 5-Fluorodeoxyuridine but not 5-Fluorouracil in Ovarian Cancer Cells-abstract
"5-Fluorouracil (5-FU) and 5-fluorodeoxyuridine (FdUrd, floxuridine) have activity in multiple tumors, and both agents undergo intracellular processing to active metabolites that disrupt RNA and DNA metabolism." "These findings underscore differences in the cytotoxic mechanisms of 5-FU and FdUrd and suggest that combining FdUrd and PARP inhibitors may be an innovative therapeutic strategy for ovarian tumors."

Proteomic biomarkers in combination with CA 125 for detection of epithelial ovarian cancer using prediagnostic serum samples from the prostate, lung, colorectal, and ovarian (PLCO) cancer screening trial
CA 125 levels were elevated (≥35 U/mL) in 61.5% of 65 patients who had CA 125 data available from samples that were collected <12 months before cancer diagnosis; however, levels of the additional 7 biomarkers were not different between cases and the 3 control groups individually or combined. Two panels that combined CA 125 and the 7 biomarkers failed to improve the sensitivity of CA 125 alone.
CONCLUSIONS:In contrast to earlier findings from analyzes of postdiagnostically collected sera, the addition of 7 biomarkers to CA 125 did not improve sensitivity for preclinical diagnosis beyond CA 125 alone.

To the Editor:
Re “How Bright Promise in Cancer Testing Fell Apart” (front page, July 8):
" The strongest evidence for reproductive disease due to asbestos is in regard to ovarian cancer. Unfortunately, effects on fertility and the developing fetus are under-studied. The possibility of other asbestos-induced health effects does exist. These include brain-related tumors, blood disorders due to the mutagenic and hemolytic properties of asbestos, and peritoneal fibrosis. It is clear from the literature that the adverse properties of asbestos are not confined to the pulmonary system."
Cochrane review: Short versus long duration infusions of paclitaxel for any advanced adenocarcinoma.
OBJECTIVES:To assess the effectiveness and toxicity of short versus long infusions of paclitaxel for any advanced adenocarcinoma.
"Adverse events were not comprehensively reported for any of the other comparisons. Outcomes were incompletely documented and QoL outcomes were not reported in any of the trials. The strength of the evidence is weak in this review as it is based on meta analyses of very few trials or single trial analyses and all trials were at moderate risk of bias and two were published in abstract form only."

► A stressful microenvironment within the endometriotic cyst may lead to cancer development.
► Ovarian clear cell carcinoma has unique gene expressions, which may serve as a molecular marker.
► Carcinogenic microenvironment affects the phenotype, character and gene expression of a cancer.

Quality of pathology reports for advanced ovarian cancer: Are we missing essential information? : : An audit of 479 pathology reports from the EORTC-GCG 55971/NCIC-CTG OV13 neoadjuvant trial
This audit of ovarian cancer pathology reports reveals that in a substantial number of reports basic pathologic data are missing, with possible adverse consequences for the quality of cancer care. Specialisation by pathologists and the use of standardised synoptic reports can lead to improved quality of reporting. Further research is needed to better define pre- and post-operative diagnostic criteria for ovarian cancer treated with neoadjuvant chemotherapy.

"An Ontario cancer researcher is concerned that the Canadian Cancer Society has proportionally shifted funding away from research and is spending more of its dollars on fundraising and administration costs.
"Most scientists don’t realize that the budget has been going up and up, and donations have been growing, but the budget for research has been shrinking," said Brian Lichty, a researcher at McMaster University who is looking into treating cancer with viruses that kill tumours. "So they are surprised and disappointed when they find out that this is the case, and the trend."
CBC's Marketplace analyzed the Canadian Cancer Society’s financial reports dating back a dozen years. It discovered that each year, as the society raised more dollars, the proportion of money it spent on research dropped dramatically — from 40.3 per cent in 2000 to under 22 per cent in 2011.........."But when Marketplace scrutinized the financial reports, it found that a greater percentage of funds was not being directed toward support, information and advocacy.........cont'd

abstract: Mechanical bowel preparation does not influence outcomes following colonic cancer resection
CONCLUSION:Neither postoperative complications nor long-term survival are improved by MBP before colonic cancer surgery.
BACKGROUND: Patients diagnosed with both breast and colorectal cancer are not uncommon and will likely be seen more often as the population ages and treatment modalities improve. Survival outcomes for such patients have not been previously reported.
METHODS: The 1988-2007 Surveillance, Epidemiology, and End Results data were used to identify women diagnosed with both breast and colorectal cancer. Disease-specific survival rates were compared.
RESULTS: We identified 4,835 women who were diagnosed with both breast and colorectal cancer. Of these, 2,844 (58.8%) were diagnosed with breast cancer first and 1,807 (37.4%) were diagnosed with colorectal cancer first; 184 (3.8%) had synchronous cancers. At 5 years following the second cancer diagnosis, 163 (3.4%) died of breast cancer and 477 (9.9%) died of colorectal cancer (P < 0.05). Comparing primary site groups between years 1 and 5 after the second cancer diagnosis showed that the relative risk of death from breast cancer declined by 46%, though it did not reach statistical significance (P = 0.24), while it significantly increased by 46% for colorectal cancer death (P = 0.0004). These findings persisted regardless of patient age, stage at diagnosis, or breast tumor histology.
CONCLUSION: For women diagnosed with both breast and colorectal cancer, the cumulative risk of death at 5 years following the second cancer diagnosis is 3 times more likely to be due to colorectal cancer than to breast cancer. Colorectal cancer specific mortality increases with time, while breast cancer specific mortality decreases with time. Consideration should be given to these findings when discussing prognosis and making treatment decisions.

Dr. Mark Kris, a cancer specialist at Memorial Sloan-Kettering Cancer Center in New York, said the flaxseed results are disappointing
"There were so many testimonials that we thought flaxseed was going to work, but a testimonial is not a rigorous clinical trial result, and that's what our patients deserve," he said.
"Even natural products do have side effects," so it's important to test them in studies such as this one, he said.

medical news: Sequence of ovarian genome identifies predominant gene mutations, points to possible treatment
"....While high-grade serous ovarian adenocarcinoma is conventionally considered as one type of cancer having uniform features, "we could divide the tumors into four different groups based on gene expression patterns," said Creighton. "They look like four different cancers."
"We were able to define a set of genes that were associated with worse outcomes versus better outcomes in patients," he said. They applied this gene signature to other sets of data collected about ovarian cancer and found that the profile predicted worse or better outcome there as well.

Cochrane Collaboration Review:Evaluation of follow-up strategies for patients with epithelial ovarian cancer following completion of primary treatment
Plain language summary
Evaluation of follow-up strategies for patients with epithelial ovarian cancer following completion of primary treatment
Ovarian cancer is the sixth most common cancer and seventh commonest cause of cancer death in women worldwide. Traditionally, many patients who have been treated for cancer undergo long-term follow up in hospitals. Whilst there may be other benefits from follow up, it has been suggested that the use of routine review may not result in women with this disease living longer given that recurrent ovarian cancer is incurable.
We set out to review the evidence for different types of follow up of women who have completed treatment for the commonest type (epithelial, that is coming from the surface of the ovary) of ovarian cancer. Only one good quality (blogger's note: Rustin trial) randomised (toss of a coin to choose which group) trial was found which could give any evidence on what to do. This trial suggested no increase in length of life from early treatment with chemotherapy for women with recurrence that was identified by a tumour marker (CA125) blood test compared to waiting to give treatment when women developed symptoms from their cancer.
We conclude that the very limited evidence suggests that there may be no benefit from early detection by the blood test and subsequent early chemotherapy for recurrent ovarian cancer. Also, the women having early chemotherapy treatment of their relapsed cancer may have led to a decreased quality of life for these women compared to the group who were treated when they noticed symptoms.
Randomised controlled trials are needed to compare different types of follow up, looking at quality of life and anxiety outcomes. If new treatments become available for relapsed ovarian cancer, the methods of follow up may need re-assessing to see if earlier intervention improves survival or other outcomes.
"But now scientists at the charity Ovarian Cancer Action have discovered the reason why their cancers apparently develop this resistance. Rather than the cancers developing immunity, they found that minute traces of cancers that were always resistant to platinum therapy were there from the beginning. This discovery has helped them identify four or five different molecular "targets" that could be the focus of new drugs, said Prof Hani Gabra, director of the charity's research centre. He said: "These cancers look like they are platinum-resistant, but in fact they were there from the outset and they were never touched by the drugs." .....cont'd

Diagnostic delay in ovarian cancer seems far from being exclusively a medical problem, as the delay proved to be influenced by organisational, cultural, and social factors, too. Initiatives facilitating the diagnostic process and research concerning the selection of individuals for further investigation are indicated. The way in which the women interpreted their symptoms was influenced by their personal experiences, their cultural, and their social background. This became crucial to the diagnostic process. These issues need to be explored through further research on women's experiences during the diagnostic process.
