Background: Multifocality is not listed among prognostic factors in international breast cancer guidelines. This study aims to analyze survival in multiple breast carcinomas (MFMC cc) compared to unifocal ones (UF cc), in order to assess the prognostic impact of multifocality.
Methods: The study included 460 breast carcinomas (2002-2006) with a median follow-up time of 104 months (74-134 months).
