[Analysis of recurrences following conservative treatment of breast carcinoma].
In the conservative treatment of early breast cancer, great attention must be paid to define the prognostic factors correlated with the local recurrence rate. The goal is to customize surgery, radiotherapy and chemotherapy to the risk predicted in every single patient. To investigate the impact of some prognostic factors in a group of patients treated with homogeneous treatment schedules, 251 women with UICC stage I or II breast cancer were examined in the Padua Radiotherapy Department from 1988 to 1990. All patients underwent conservative surgery consisting in quadrantectomy, axillary node dissection and radiotherapy. During a median follow-up period of 49.2 months, 12 patients presented a breast relapse (4.8%). In 4 patients the relapse occurred in the same quandrant as the primary lesion, whereas a different quadrant was involved in the other 8 patients. The relapse rate in women under 60 was 5% and 4.7% in older patients, with p = 0.73. In pT1 patients, the relapse rate was 4.5% and in pT2 patients it was 7.9% (p = 0.37). No significant difference was observed between pN- and pN+ patients (4.5% vs. 6.25%, p = 0.37). In our series, none of the studied factors significantly influenced breast relapse rates. The number of patients may be too little relative to the low rate of relapses. However, an unfavorable trend was observed in the patients under 60, in pT2 or pN+ patients, or in the patients with positive or unknown surgical margins.
