To aid in the selection of breast cancer patients for adjuvant chemotherapy, 263 patients with primary breast carcinoma undergoing curative surgery at the Yale-New Haven Medical Center were examined with respect to axillary lymph node involvement and prognosis.
Thirty-five percent of patients with one to three axillary nodes histologycally involved with cancer relapsed within five years, as did 61% of patients with four or more cancer-positive nodes. Equally important was the clinical stage. Stage III patients had a poor prognosis (71% relapse rate) regardless of their axillary status. Stage I patients with metastasis to one to three axillary nodes did just as well as stage I patients with no nodal involvement (13% relapse rate). Relapse rates within the nodal categories are significantly less (P <.05) than those reported by the National Surgical Adjuvant Breast Project.
