[Gynecological and breast cancer in the department of Somme]. / Cancers gynécologiques et mammaires dans le département de la Somme.

BACKGROUND: Breast and gynecological tumors are the most common cancers in women. The aim of this study was to show the epidemiologic features of gynecological and breast cancers in the French administrative district of La Somme. METHODS: This study focused on the 1982-1999 period. Incidence, mortality and survival rates were calculated. RESULTS: In 1997-1999, the world standardized breast incidence and mortality rates were 81.6 and 20.2 per 100,000 females per year. Breast and genital tract cancers accounted for 47% of all cancers in women. The incidence and mortality of uterine cervix cancers showed a clear decline over the past 10 years, whereas the trend of breast cancers was dominated by continuing increase. However, mortality was stable for breast cancers. Five year relative survival rates were respectively 80% for breast cancers, and 68%, 76%, 38%, for uterine cervix, uterine body and ovary cancers respectively. Incidence and mortality rates in Somme were in the middle risk range of other cancer French registries. CONCLUSION: The results of this study indicate that genital tract and breast cancers constitute a serious public health problem pointing out the importance of screening activities in the Somme area.

[Incidence and prevalence estimations for breast and colorectal cancer in the Picardy region]. / Estimation de l'incidence et de la prévalence du cancer du sein et du cancer colorectal dans la région de Picardie.

OBJECTIVES: To provide incidence and prevalence data on breast and colorectal cancer in the Picardie area of France. METHODS: An age-period-cohort method was used to estimate regional incidence and prevalence of cancer from regional cancer mortality data and patient survival data recorded in the Somme Cancer Registry. RESULTS: European standardized breast incidence for 1998 was 110 per 100000 inhabitants. The incidence for colorectal cancer was 67 per 100000 for men and 47 per 100000 for women. Prevalence was 9656 for breast cancer and 6283 (2941 for men and 3342 for women) for colorectal cancer. Incidence of breast cancer increased considerably (80.9%) between 1979 and 1998. CONCLUSION: These results provide data on breast cancer and colorectal cancer which are useful for planning demand for healthcare or medical surveillance in the Picardie area.
