The objective of this study was to identify the anatomical-clinical aspects and determine the prognostic factors for breast cancer in the central region of Tunisia. This retrospective study involved 729 patients suffering from breast cancer, proven either by histology or cytology, diagnosed and treated between January 1990 and June 1998 at the F. Hached University Hospital in Sousse, Tunisia. The patients’ average age was 50 years (ranging from 22-91). The average size of the cancer at the time of diagnosis was 49.1 mm; 90 % were invasive duct carcinoma with high histo-prognostic SBR grade (level II – III: 86%). The overall survival rate was 50.5% after five years, and 50 % after seven years. Using univariate analysis, significant predictive value was found with the following factors: tumor size, the clinical ganglionic level, metastases at diagnosis, the number of nodes invaded, nodal capsular rupture and lymphatic embolism, SBR grade and the delay in seeking consultation. The multivariate analysis (Cox model) isolated two prognostic factors: the initial size of the tumor (p = 0.001) and metastases at the time of diagnosis (p = 0.01). The study’s results indicated that breast cancer prognosis in Tunisia remains poor primarily due to late diagnosis.
