title: [Departmental compilation of histoprognostic data in senology. Apropos of campaign screening in Bouches-du-Rhône].
abstract: In January 1990 a registry for cases of breast cancer occurring in the Bouches-du-Rhone area was set up in conjunction with a screening programme for women over 50 years of age. The aim of this study was to compare histoprognostic findings of unscreened patients (A) with a palpable lesion, screened patients (B) with or without a palpable lesion and self screened patients (C) registered for clinically occult mammary carcinoma. The histoprognostic criteria studied were: histological type, tumor size, prognostic grade and axillary lymph node involvement. Of the 2,478 surgical procedures registered, 1,125 involved women over 50 years of age including 47% with malignant disease. Only 3.7% of screened patients presented intraductal carcinoma compared with 1.17% to 18.2% of unscreened A or self-screened C patients. The incidence of minimal infiltrating breast cancer smaller than 10 mm varied widely from 17.3% in A patients to 33.7% in B patients and 51.4% in C patients (P < 0.001). The incidence of histoprognostic grade III tumors ranged from 17.9% in A patients to 10% in B patients and 4.3% in C patients (P < 0.007). Lymph node involvement decreases from 41% in A to 28% in B patients and 23% in C patients (P = 0.01). Based on our data, 41.9% of screened patients were in the most favorable prognostic category, ie intraductal carcinoma or infiltrating carcinoma less than 10 mm or grade I and no lymph node involvement, versus only 26.1% of A patients and 60.9% of C patients (P < 0.0001). Information of the incidence, pathology of interval tumors in previously screened women will be evaluated in the future. This first study underscores the necessity for this kind of registry to evaluate the histoprognostic profile year by year of a breast cancer screening campaign.
