On a population-based sample of 13,500 European breast cancer patients mostly diagnosed in 1996-1998 and archived by 26 cancer registries, we used logistic regression to estimate odds of conservative surgery plus radiotherapy (BCS + RT) versus other surgery, in T1N0M0 cases by country, adjusted for age and tumour size. We also examined: BCS + RT in relation to total national expenditure on health (TNEH); chemotherapy use in N+ patients; tamoxifen use in oestrogen-positive patients; and whether ≥10 nodes were examined in lymphadenectomies. Stage, diagnostic examinations and treatments were obtained from clinical records. T1N0M0 cases were 33.0% of the total. 55.0% of T1N0M0 received BCS + RT, range 9.0% (Estonia) to 78.0% (France). Compared to France, odds of BCS + RT were lower in all other countries, even after adjusting for covariates. Women of 70-99 years had 67% lower odds of BCS + RT than women of 15-39 years. BCS + RT was 20% in low TNEH, 58% in medium TNEH, and 64% in high TNEH countries. Chemotherapy was given to 63.0% of N+ and 90.7% of premenopausal N+ (15-49 years), with marked variation by country, mainly in post-menopause (50-99 years). Hormonal therapy was given to 55.5% of oestrogen-positive cases, 44.6% at 15-49 years and 58.8% at 50-99 years; with marked variation across countries especially in premenopause. The variation in breast cancer care across Europe prior to the development of European guidelines was striking; older women received BCS + RT much less than younger women; and adherence to 'standard care' varied even among countries with medium/high TNEH, suggesting sub-optimal resource allocation. © 2010 Elsevier Ltd.

Cancer mortality in elderly people is described to highlight the mechanisms that could potentially explain observed differences with other age groups. Data from 15 French cancer registries were considered in the search for the 5-year outcome of patients diagnosed during the period 1989-1997. Relative survival, excess mortality hazard, and hazard ratio of mortality were estimated to describe patient outcome according to age. Five cancer sites were selected: colon/rectum, prostate, breast, head/neck, and lung. An excess mortality rate was found in patients aged over 75 at the time of diagnosis. This excess mortality rate was mainly seen during the first months after diagnosis, then it decreased gradually with time. An initial phenomenon of patient selection, a greater disease severity at the time of diagnosis, and less-effective treatments given to elderly patients are the most plausible explanations for the increased risk of cancer-related death in the eldest patients. © 2009 UICC.

Background: To provide estimations of partial and total prevalence of 24 cancer sites in France in 2008. The estimations of partial prevalence were compared with the previous estimations for 2002. Methods: Nationwide estimations of incidence and survival data from cancer registries were used for partial prevalence. Nationwide incidence and mortality data were used to estimate total prevalence. Results: At the end of 2008, in France, nearly 3 million people still alive had received a diagnosis of cancer. Of all prevalent cases, 36% were diagnosed 0 to 5 years earlier and 43% diagnosed 6 to 10 years earlier. The cancer sites with the highest prevalence were the prostate, the breast, and the colon-rectum. The changes in partial prevalence over 5 years (2002 to 2008) were considerable (+244,000 cases) and deemed to be highly related to changes in incidence. Conclusion: The present estimations update the French prevalence data and highlight the burden of cancer in the population, especially in the elderly. The methods of this study had the advantage of using recent incidence and survival data, which is necessary to show sudden changes in incidence trends and changes in survival that impact prevalence. © Colonina et al. licensee BioMed Central.

Young women are not usually screened for breast cancer (BC). The trends in incidence in this population may better reflect changes in risk factors. However, studies on this subject are scarce and heterogeneous. The aim of this study was to describe the trends in incidence of BC in women under 40 from 1990 to 2008, using pooled European data. Thirty-seven European population-based cancer registries from Belgium, Bulgaria, France, Italy, Portugal, Spain and Switzerland participated in this study. World age-standardized incidence rates were first analyzed graphically and then using a Poisson regression model, in order to estimate average annual percent changes (AAPCs). The overall incidence rate of BC in the area covered increased linearly during the study period by 1.19% (0.93; 1.46) on average per year. This increase varied between countries from 0.20% (-0.53; 0.64) in Bulgaria to 2.68% (1.97; 3.40) in Portugal. In Italy, after a significant rise of 2.33% (1.14; 3.54) per year, BC incidence began decreasing in 2002 by -2.30% (-4.07; -0.50) yearly. The rise in incidence was greater for women under 35 and for ductal carcinomas. This increase can be due to a rise in risk factors and/or changes in diagnosis and surveillance practices, but we could not clearly distinguish between these two non-exclusive explanations. © 2013 Elsevier Ltd.

Background To evaluate quality of life (QoL) 10 years after treatments for localised prostate cancer (LPCa) patients in comparison with aged-matched healthy controls. Methods LPCa patients diagnosed in 2001 were obtained from 11 French cancer registries. Controls were recruited among the general population and were matched to patients on age and geographic area. EORTC Quality of Life Questionnaire - Core 30 items, Expanded Prostate Cancer Index Composite, Hospital Anxiety and Depression Scale and Multidimensional Fatigue Inventory self-reported questionnaires were used to measure QoL, anxiety and fatigue. Patients were classified in three groups according to previous treatments: radical prostatectomy (RP), radiotherapy (RT) and radical prostatectomy and radiotherapy (RP+RT). The differences in QoL between patients and controls and according to treatment groups were evaluated. Results There were 287 patients and 287 controls. There was no socio-demographic difference between patients and controls. Treatments were: RP (143), RT (78), PR+RT (33), baseline hormone therapy (49) and hormone therapy at the time of the study (34). Patients had similar levels of global QoL, anxiety, depression and fatigue as controls. They reported more urinary troubles (urinary function and incontinence) (p < 0.0001) and more sexual dysfunctions (p < 0.0001) than controls, whatever the treatment group. Worse bowel dysfunction was reported in patients treated by RT and RP+RT (p < 0.002). According to the treatments, RP groups had the worst urinary function and incontinence (p < 0.01), and reported more bowel bother when the treatment was combined with RT. Conclusions Even though patients reported similar global QoL as control 10 years after treatment, patients reported numerous urinary and sexual dysfunctions. Patients treated with RP+RT reported cumulative sequelae of both treatments. © 2016 Elsevier Ltd. Source
