[Cancer of the breast in Cote-d'Or (1982-1987). The Burgundian register of gynecologic diseases].
Burgundian registry of gynaecological pathology, formed in 1982 is involved in the study of epidemiologic and clinical features of breast cancer in the district of Côte-d'Or. One thousand two hundred and twenty nine new cases were recorded from 1982 to 1987. Crude incidence was 82.8/100,000 women. Age standardised incidence, based on world standard population was 63.4/100,000 women. Incidence of breast cancer was higher in urban areas (66.0/100,000 women) than in rural (55.0/100,000 women) areas. In comparison with data of other cancer registries, women from Côte-d'Or are in the high risk group. Histological diagnosis was reported in 97% of cases. The most frequent histologic types were infiltrating duct carcinoma (81.6%) and infiltrating lobular carcinoma (4.4%). Non-invasive carcinoma was present in 4.2% of cases; 4.8% of patients presented metastases at the time of primary diagnosis. Sixty four percent of tumors measured less than 30 mm (on gross specimen). Frequency of axillary nodal involvement was lower than 20% for tumors which measured less than 10 mm but increased up to 40% for larger tumors. From a therapeutic point of view, 91% of patients underwent mammary surgery, 67% underwent radiotherapy and 44% underwent chemotherapy and/or hormonotherapy. Five-year observed actuarial survival rate was 68%, corrected 75% and specific 77%. These results point out the necessity of extensive use of mammography for screening of small breast tumors which have a low risk of nodal involvement.
