Abstract

Several reports have indicated that young women (less than 40 years of age) with breast cancer have a worse prognosis than older women. We performed a case-control study in order to confirm this observation and to determine whether this was attributable to increased microvessel density (MVD) or p53 expression. Twenty-six young women (cases) with stage I-III breast cancer that had adequate paraffin-embedded archival tissue were identified by the Montefiore Medical Center Tumor Registry over a 24-year period. For each case, two or three control subjects at least 40 years of age or older were selected from the registry and matched for nodal status and tumor size. Immunohistochemistry was performed for MVD and p53 overexpression. A Cox proportional hazard model was performed to examine the influence of age, MVD, p53 overexpression, and recognized prognostic factors on disease-free and overall survival. There were 26 cases (median age, 36 years) and 72 controls (median age, 64 years). The groups were well matched for known prognostic variables. There was no significant difference in p53 overexpression or MVD in the cases and controls. In multivariate analysis, the only features associated with an increased risk of recurrence included young age (hazard ratio [HR] = 2.49; 95% confidence interval [CI]: 1.18-5.25; P = 0.02) and positive lymph nodes (HR =2.44; 95% CI: 1.12-5.30; P = 0.02). We have confirmed previous reports demonstrating a worse prognosis for women younger than 40 years with invasive breast cancer but found no correlation between young age and MVD or p53 overexpression when adjusted for other variables.
