paywalled - Survival of ovarian cancer patients in Germany in the early 21st century: a period analysis by age, histology, laterality, and stage



European Journal of Cancer Prevention:

Abstract

Population-based studies on ovarian cancer providing survival estimates by age, histology, laterality, and stage have been sparse. We aimed to derive the most up-to-date and detailed survival estimates for ovarian cancer patients in Germany. We used a pooled German national dataset including data from 11 cancer registries covering 33 million populations. A total of 21 651 patients diagnosed with ovarian cancer in 1997-2006 were included. Period analysis was carried out to calculate the 5-year relative survival (RS) for the years 2002-2006. Trends in survival between 2002 and 2006 were examined using model-based period analysis. Age adjustment was performed using five age groups (15-44, 45-54, 55-64, 65-74, and 75+ years). Overall, the age-adjusted 5-year RS in 2002-2006 was 41%. A strong age gradient was observed, with a decrease in the 5-year RS from 67% in the age group 15-49 years to 28% in the age group 70+ years. Furthermore, the prognosis varied markedly by histology, laterality, and stage, with the age-adjusted 5-year RS ranging from 25% (for carcinoma not otherwise specified) to 81% (for stromal cell carcinoma), reaching 46% for unilateral and 32% for bilateral carcinoma and reaching 82% for Federation of Gynecology and Obstetrics (FIGO) stages I and II, 36% for FIGO stage III, and 18% for FIGO stage IV. No improvement in survival could be observed for any of the subgroups in the period between 2002 and 2006. Our analyses suggest that an improvement in the 5-year RS for ovarian cancer may have stagnated in the early 21st century and underline the need for a more effective translation of therapeutic innovation into clinical practice.

Editorial: Clinical Trials in Elderly Ovarian Cancer Patients – Does It Make Sense? (Germany)



Editorial: Clinical trials in elderly ovarian cancer Patients - Does It Make Sense?

 "Clinical research needs clinical trials, new and generally
applicable knowledge can only be acquired if the young and
the old participate in clinical trials."

Treatment of Elderly Ovarian Cancer Patients in the Context of Controlled Clinical Trials: A Joint Analysis of the AGO Germany Experience

Summary
 
Background:

Age remains a negative prognostic factor in ovarian cancer (OC). 3 separate analyses by the AGO (Arbeitsgemeinschaft Gynaekologische Onkologie) give insight into the treatment of elderly patients (EPs) in the context of controlled clinical trials (CCTs).

Methods:
1 retrospective study evaluated the reasons for non-enrolment into CCTs of patients with advanced OC in AGO centers. 2 other exploratory age-specific analyses of a phase III trial in advanced OC treated with platinum/ paclitaxel evaluated (1) feasibility, toxicity and quality of life (QoL) and (2) the clinical outcome.  

Results: 
Non-study patients were significantly older (66.7 vs. 57.2 years). Reasons for non-enrolment were predominantly predefined exclusion criteria, numeric age, and the patient’s decision. The phase III trial confirmed an under-representation of EPs. Cycle delivery was significantly lower and discontinuation more frequent in EPs than in younger patients (YPs), although QoL, toxicity, cycle delays, and dose reductions were comparable. Delivery of cycles was prognostically significant in EPs but not YPs. The survival advantage of YPs remained significant even in completely debulked patients.

Conclusion:
There is some kind of investigator reservation for the treatment of EPs, which not only applies for the enrolment into clinical trials but also for the treatment, even under CCT conditions, with impact on outcome.

Multinational Comparisons of Health Systems Data, 2011 - The Commonwealth Fund including link to 2011 patient care coordination (11 countries)



"International comparisons of health care systems offer valuable tools to health ministers, policymakers, and academics wishing to evaluate the performance of their country's system. In this chartbook, we use data collected by the Organization for Economic Cooperation and Development (OECD) to compare health care systems and performance on a range of topics, including spending, hospitals, physicians, pharmaceuticals, prevention, mortality, quality of care, and prices. We present data across several industrialized countries: Australia, Canada, Denmark, France, Germany, Japan, the Netherlands, New Zealand, Norway, Sweden, Switzerland, the United Kingdom, and the United States. Whenever possible, we also present the median value of all 34 members of the OECD.......

abstract: A comparison of international breast cancer guidelines - Do the national guidelines differ in treatment recommendations? USA, Canada, Australia, the UK, and Germany



(USA, Canada, Australia, the UK, and Germany)
 CONCLUDING STATEMENT: Considering that the development of guidelines is a very expensive and resource-intensive task the question arises whether the development of national guidelines in numerous countries is worth the effort since the recommendations differ only marginally.

full free access: Research output on primary care in Australia, Canada, Germany, the Netherlands, the United Kingdom, and the United States: bibliometric analysis - bmj.com



What is already known on this topic

  • The UK Research Assessment Exercise in 2008 rated 50% of UK primary care research as world class or internationally excellent, but no direct international comparisons exist

What this study adds

  • In six countries with strong primary care, the United Kingdom and the Netherlands produce the most cited primary care led primary care research
  • Identifying research on primary care that is carried out by primary care researchers is difficult using routine bibliometric methods
  • Only 29% of research papers on primary care had at least one primary care researcher as author
