Objective. To identify disparities in the management of colon and rectal cancer across Europe by assessing population-based information from 12 European cancer registries (CR) participating in EUROCARE, together with additional information obtained from individual clinical records. Methods and patients. We considered five indicators: (a) resection with curative intent; (b) post-operative mortality; (c) proportion of stage II/III colon cancer cases given adjuvant chemotherapy; (d) proportion of rectal cancer cases receiving radiotherapy; and (e) proportion of curative intent resections with 12 or more lymph nodes examined. Results. A total of 6 871 colorectal cancer patients, diagnosed between 1996-1998, were examined. Overall 71% of patients received resection with curative intent, range 44-86% by CR; 46% of stage III colon cancer cases (range 24-73% by CR) and 22% of stage II cases (not then recommended) received adjuvant chemotherapy; 12% of rectal cancer cases received adjuvant radiotherapy, range ≤2% in five CRs to >51% in two CRs. For only 29% of curative intent resections were 12 or more lymph nodes examined. Conclusions. This study reveals that, although most patients received surgery with curative intent, disparities in treatment for colorectal cancer across Europe in the late 1990s were unexpectedly large, with many patients not receiving treatments indicated by published clinical trials. Consensus guidelines for CRC management are now becoming available and should be adopted across Europe. It is hoped that dissemination of guidelines will improve the use of scientifically proven treatments for the disease, but this should be monitored by further population-based studies. © 2010 Informa UK Ltd.

Background: Wide geographic variations in survival for gastric cancer in Europe have been reported. The aim of this study was to analyse the effect of stage at diagnosis, treatment and cancer characteristics on long-term survival for gastric cancer in populations covered by cancer registries. Methods: We analysed survival in 4620 cases of gastric cancer from 17 European population-based cancer registries from 8 countries. Univariate and multivariate regression of relative survival were performed. Results: Five-year relative survival varied between 10.6% and 24.0%, while 10-year survival ranged from 7.7% to 23.0%. After adjustment for age and sex, the regional excess hazard ratio (EHR) of death was significantly higher in Ragusa, Granada, Yorkshire, Slovakia, Slovenia and Poland than in France, Northern Italy, The Netherlands and the Basque Country. After further adjustment for surgical resection versus no resection (a proxy of stage), the EHR of death remained significantly higher only in Granada and Yorkshire than in the reference country (France). After adjustment for stage, the EHR was significantly higher only in Yorkshire (EHR: 1.51; 95% confidence interval (CI): 1.29-1.77). The EHR in this area was limited to the first year following diagnosis. Conclusion: Differences across Europe in gastric cancer survival depend to a large extent on differences in stage at diagnosis. However they do not explain all variations. Quality of management and treatment can explain some differences. © 2010 Elsevier Ltd. All rights reserved.

The aim of this study was to report on malignant digestive endocrine tumours (MDET) prognosis in several European countries. We analysed survival data from 19 cancer registries in 12 European countries on 3,715 MDET diagnosed between 1985 and 1994. The overall 5-year survival rate was 47.5%. It was 58.1% for differentiated MDET and 8.1% for small-cell MDET (p < 0.001), 55.9% for patients under 65 and 37.0% for older patients. Survival rates for small intestinal and colorectal were higher than for the other sites. The 5-year relative survival rates were 60.3% in Northern Europe, 53.6% in Western Continental Europe, 42.5% in the UK, 37.6% in Eastern Europe (p < 0.001). Among well-differentiated pancreatic tumours, 5-year relative survival was 55.6% for insulinoma, 48.4% for gastrinoma, 33.4% for glucagonoma, 28.8% for carcinoïd tumours and 49.9% for non-functioning tumours. The relative excess risk of death was significantly lower in Western Continental Europe and Northern Europe and significantly higher in Easter European compared to the UK. MDET differentiation, site, geographic area, age and sex, were independent prognostic factors. Overall, in Europe approximately half of the patients with MDET survive 5 years after the initial diagnosis. Prognosis varies with tumour differentiation, anatomic site and histological type. There are significant differences in survival from MDET among European countries, independently of other prognostic factors.

Background: Little is known at a population level about operative mortality after surgery for gastric cancer and whether differences between countries can explain differences in long-term survival. This study compared operative mortality recorded by ten cancer registries in seven European countries. Methods: Non-conditional logistic regression analysis was performed to estimate the independent effect of the studied factors onmortality within 30 days of surgery. A multivariable survival model was employed with and without operative mortality. Results: The overall operative mortality rate in 1611 patients studied was 8.9 (range 5.2-16) per cent. Country of residence was a significant prognostic factor in the multivariable analysis. The likelihood of operative mortality was lower in Italy, France and the UK than in the Netherlands, Spain, Slovenia and Poland. Age, type of gastrectomy and stage at diagnosis were also significant factors. Cancer site was not found to be significant in the multivariable analysis. The overall 5-year relative survival rate varied between 42.0 per cent (Italy) and 24 per cent (Poland); after excluding operative mortality, the 5-year survival rate was 44.3 and 28 per cent respectively. Conclusion: Within Europe, the substantial differences in operative mortality after gastrectomy only partly explain marked differences in survival after gastric cancer resection.

Kaposi sarcoma (KS) is a virus-related malignancy which most frequently arises in skin, though visceral sites can also be involved. Infection with Kaposi sarcoma herpes virus (KSHV or HHV-8) is required for development of KS. Nowadays, most cases worldwide occur in persons who are immunosuppressed, usually because of HIV infection or as a result of therapy to combat rejection of a transplanted organ, but classic Kaposi sarcoma is predominantly a disease of the elderly without apparent immunosuppression. We analyzed 2667 KS incident cases diagnosed during 1995-2002 and registered by 75 population-based European cancer registries contributing to the RARECARE project. Total crude and age-standardized incidence rate was 0.3 per 100,000 per year with an estimated 1642 new cases per year in the EU27 countries. Age-standardized incidence rate was 0.8 per 100,000 in Southern Europe but below 0.3 per 100,000 in all other regions. The elevated rate in southern Europe was attributable to a combination of classic Kaposi sarcoma in some Mediterranean countries and the relatively high incidence of AIDS in several countries. Five-year relative survival for 2000-2002 by the period method was 75%. More than 10,000 persons were estimated to be alive in Europe at the beginning of 2008 with a past diagnosis of KS. The aetiological link with suppressed immunity means that many people alive following diagnosis of KS suffer comorbidity from a pre-existing condition. While KS is a rare cancer, it has a relatively good prognosis and so the number of people affected by it is quite large. Thus it provides a notable example of the importance of networking in diagnosis, therapy and research for rare cancers. © 2014 Elsevier Ltd.
