Analysis of prognostic factors in patients with isolated chest wall recurrence of breast cancer

Abstract

A retrospective analysis of a series of 162 patients treated for isolated chest wall recurrence of breast cancer after mastectomy was undertaken. Cumulative survival, distant relapse-free survival, and freedom from local progression after 5 years from the diagnosis of recurrence were 34%, 28%, and 45% respectively. Five prognostic factors influenced survival: axillary node status, primary T stage, length of disease-free interval, and number and size of recurrences. Four prognostic factors influenced the local control: axillary node status, primary T stage, disease-free interval, and number of recurrences. Patients with three or more, out of five, favorable prognostic factors fared much better than those with two or less: 75% versus 15% survival at 5 years. Our findings suggest that it is possible to identify a group of patients with a distinctly good medium-term survival and local control of disease.
