PREDICTING LOCAL RECURRENCE IN PATIENTS W ITH INTRADUCTAL BREAST-CARCINOMA - ABOUT 217 CASES

The authors have reviewed 217 cases of pure intraductal carcinomas wit h a mean follow-up of 98 months (with 2 deaths out of 31 reccurences f rom which 35% into adenocarcinomas). The data concerning the diagnosis , the tumor size, the pathological type, the surgical treatment more o f less associated to radiation therapy are detailed. The aim of this w ork was to give a more reliable way or approaching the recurrence rate (31/217) to be able to apply a more conservative treatment to these c ases. The lymph node dissection and removal seams to be useless in the in situ carcinomas Concerning the tumor size, the local tumors can be treated by conservative surgical procedures and do not get any benefi t from radiotherapy The opposite is true concerning more largely invas ive tumor Concerning the histology, the non-comedocaucinomatous tumors get less benefit from radiotherapy than the comedocarcinomatous type. The study of the tumor limits and the reliquats seem to be useful. Th e treatment chosen and applied remains the major agnostic element in t he probability of recurrence.
