Menopausal Status and the Impact of Early Recurrence on Breast Cancer Survival

BACKGROUND: Breast cancer represents the leading form of invasive cancer among American women, killing nearly 50,000 annually. Several prognostic factors that are associated with survival include age, race, menopausal status, and the stage of disease at presentation. METHODS: Patient characteristics were collected based on a systematic chart audit of demographic features and medical, family, and social histories. We studied the survival of 220 patients with recurrent disease out of 1,429 consecutive patients with breast cancer seen over a 15-year period. RESULTS: Patients with a disease-free interval following diagnosis of less than 24 months were more frequently premenopausal and hormone receptor-negative than those with a disease-free interval of 24 months or greater. Patients with early recurrence had a shorter survival than patients with late recurrence. Menopausal status, nodal involvement, receptor status, and the site of recurrent disease were independent predictors of survival following recurrence. CONCLUSIONS: Premenopausal women with early recurrence of breast cancer experience a significantly shorter survival than those with late recurrence, even after adjustment for hormone receptor status and site of recurrence. This effect was not seen in postmenopausal women.
