Abstract
BACKGROUND: Breast carcinoma is relatively uncommon in younger women and whether or not young age at diagnosis is an adverse prognostic factor in this disease has been controversial. Our aim in this report is to determine whether the histopathologic features and outcome in young and old are different, and whether age is a prognostic factor for relapse. METHODS: A retrospective study of consecutive 281 stage I or II breast carcinoma patients who had modified radical mastectomy was carried out. The patients with a median follow-up period of 45 months were divided two groups according to their ages. The histopathological features and survival of Group 1 and Group 2 were compared with each other. Univariate and multivariate prognostic factor analysis for relapse were carried out. RESULTS: The patients in Group 1 (younger than 35 years of age) had the worst histopathological features related to the prognosis than those in Group 2 and the difference between the two groups was statistically significant. Whereas the rates of 5-year overall survival were 65% in Group 1 and 98% in Group 2 (P < 0.05), the rates of 5-year relapse-free survival were 40% and 80%, respectively (P < 0.05). In univariate analysis of all patients, pathologic tumour size, pathologic axillary status, number of metastatic lymph nodes, pathologic stage, age, lymphatic vascular invasion were statistically significant factors associated with relapse. Multivariate analysis demonstrated that number of metastatic nodes (risk ratio RR:4.3 in more than three nodes) and age (RR:3.6 in Group 1) were the most important independent prognostic factors for relapse. In the patients without axillary involvement, both of univariate and multivariate analysis revealed that pathologic tumour size (RR:5.1 in pT(2)) and age (RR:4 in Group 1) were the independent prognosticators for relapse. CONCLUSIONS: Young patients with breast cancer had the worst histopathological features and the worst survival than their older counterparts. Age was an independent significant prognostic factor for relapse. Copyright 2000 Wiley-Liss, Inc.
