RESUMO
PURPOSE OF THE STUDY: Elderly breast cancer (EBC) patients are often denied adjuvant chemotherapy because of age. Breast cancer is among the most frequent cancer in Western Countries and recent data suggest that adjuvant chemotherapy could be active in selected elderly patients. We investigated the impact of age and comprehensive geriatric assessment (CGA) among other variables taken into account in tumor boards to recommend adjuvant chemotherapy in EBC patients. METHOD(S): We retrospectively reviewed breast cancer tumor board records of all consecutive EBC patients (over 70 years old) discussed from July 2006 to July 2009 in our institution. The recorded variables included age, comorbidities, tumor stage, grade, ER/PR and HER2 status, treatment characteristics and CGA conclusions. Agreement with breast cancer treatment guidelines was verified. Reasons for deviations were recorded. RESULT(S): A total of 192 early EBC patients files (mean age 76.7 years, range 70-98) were analyzed. Elderly patients were less likely to receive adjuvant chemotherapy even when deemed appropriate by guidelines (p<.001). Out of 118 patients with ≥1 risk factors (pT2-4, N+, RH-, SBR III), 70 were proposed adjuvant chemotherapy. In multivariate analysis, age >80 years, but not CGA result, was an independent variable associated with a decreased likelihood to receiving adjuvant chemotherapy. Moreover, 93 patients (48.4%) underwent CGA, of whom no Balducci's class III patient received adjuvant chemotherapy. An appropriate treatment was administered in only 69% and 42% of Balducci's class I and II patients, respectively. CONCLUSION(S): Our results suggest that age remains an independent variable associated with a decreased use of adjuvant chemotherapy. However, in our series systemic adjuvant chemotherapy was probably underused in "fit" patients. Further efforts are needed to better integrate CGA into tumor boards proposals for early EBC patients.
