title: Prognostic factors after 5 years follow-up in female breast cancer.
abstract: A consecutive series of breast carcinomas (n = 595) followed up for a minimum of 7.5 years was analyzed for clinical, histological and morphometric prognostic factors after 5-years' follow-up. Tumor size, nodal status, mitotic frequency and patients' age at diagnosis predicted survival at 7.5 years highly significantly (p less than 0.0001). Tubule formation (p = 0.002), histological grade (p = 0.026) and nuclear pleomorphism (p = 0.046) were related to prognosis as well. In N--patients mitotic frequency (p = 0.018) was the best predictor of survival at 7.5 years whereas in N + tumors tumor size (p = 0.0013), tubule formation (p = 0.003) and mitotic frequency (p = 0.0049) were the best predictors of survival at 7.5 years. In univariate survival analysis the age of the patients (p = 0.002), tubule formation (p = 0.005), axillary lymph node status (p = 0.008), lymphocyte infiltration (p = 0.049), mitotic frequency (p = 0.06) and tumor size (p = 0.08) predicted survival after 5 years' follow-up. Tubule formation predicted survival (p = 0.025) in N - patients and in N + tumors the age of the patients was the most important predictor (p = 0.006). In Cox's analysis tubule formation (p = 0.13), axillary lymph node status (p = 0.033), SD of nuclear perimetry (p = 0.046) and intraductal growth (p = 0.059) predicted survival independently after 5 years' follow-up.
