    PurposeTo examine the prognosis of breast cancer patients (T1-3, one to three positive axillary lymph nodes) and locoregional failure rate after breast-conserving therapy/modified radical mastectomy and adequate axillary dissection following tangential radiotherapy without irradiation of the regional lymph nodes.Patients And MethodsFrom 1994 to 2002, the medical records of 183 breast cancer patients (T1-3, one to three involved axillary lymph nodes) were examined in order to identify those experiencing regional nodal recurrence, with or without local recurrence. The median age of the patient population was 58 years (range, 28-86 years). All patients underwent surgical treatment, either breast-conserving therapy (n = 146) or modified radical mastectomy (n = 37). The median number of lymph nodes removed was twelve (range, seven to 26 nodes). Irradiation was given to the breast through tangential fields. Chemotherapy was administered to 101 patients (55%), hormonal therapy to 124 (60%), and combined systemic treatment to 47 (26%).ResultsThe median observation time was 44.4 months (range, 11-102 months). Of the 14 patients (7.7%) with a relapse, six (3.3%) had a local recurrence, five (2.8%) a regional relapse, and three (1.6%) a simultaneous recurrence. Nine out of 14 patients with locoregional relapse developed distant failure subsequently and seven of them (78%) died of the disease.ConclusionRegional recurrence is uncommon among patients with one to three positive axillary lymph nodes treated with surgery, adequate axillary dissection, and tangential field irradiation only. The authors conclude that regional nodal irradiation should not routinely be given following adequate axillary dissection when only one to three lymph nodes are positive.
