Breast conserving treatment (BCT) for stage I-II breast cancer in elderly women: analysis of 927 cases.
BACKGROUND
Few breast conserving treatment (BCT) data include women older than 70.


METHODS
910 women older than 70 were treated by BCT for stage I-II BC, with 670 pT(1) (72.3%), 245 pT(2) (26.4%) and 12 pT(x) (1.3%). Axillary nodal involvement occurred in 30.7% of cases. ER and PgR were positive in 85% and 71% of cases. Radiotherapy (RT) was delivered in all patients, tamoxifen in 55.8% and chemotherapy in 4.8%.


RESULTS
With a 65-month median follow-up, 28 (3%) local recurrences (LR) and 83 (9.1%) metastases occurred. Second cancer occurred in 51 (5.6%) patients. The 8-year overall survival (OS) and disease-specific survival (DSS) rates were 74% and 90%. The 8-year OS and DSS rates were 77% and 92% versus 65% and 84% in pT(1) versus pT(2) patients (p=0.01). 676 patients were in complete remission (74.3%); 22 were evolutive (2.4%). 206 patients died (22.6%).


CONCLUSIONS
Our study confirms the excellent local control in elderly patients treated by BCT with RT and identifies subgroups at high risk of distant relapse that should be treated more aggressively.
