The Influence Of Obesity On Results Of AT (Doxorubicin Plus Docetaxel) Neoadjuvant Chemotherapy In Locally Advanced Breast Cancer Patients
The achieve pathologic complete response is proven to be the most important parameter of prognosis. Thereports evaluating the impact of obesity on the obtained pathologic response to chemotherapy are unequal. The aim of the study was to evaluate in locally advanced breast cancer patients, treated with AT(doxorubicin plus docetaxel) neoadjuvant chemotherapy: 1. The relationship of obesity with obtaining pathological response. 2. The relationship of obesity and free of disease recurrence survival (DFS) and overall survival (OS) associated with the tumour. Material and methods. A retrospective study was carried out in a group of 105 patients with locally advanced breast cancer, treated with AT neoadjuvant chemotherapy and then treated with radical surgery. Two variants of pathological response have been adopted: a pCR (T0N0) and pCR1 (TisN0, TxN1, T1N0, T1N1, T0N1). The relationship of obesity with pathological response and survival was investigated. Results. In univariate analysis the pCR1 was obtained with its arising from the borderline of statistical significance with lower incidence of obesity. In pCR1 multivariate analysis, negative pCR1 relationship with obesity was on the borderline of the statistical significance. The multivariate analysis showed a significant negative association OS with obesity (p=0.047) and positive with the occurrence of menopause (p = 0.029). Conclusions. In patients with locally advanced breast cancer treated with AT neoadjuvant chemotherapy. 1. Obesity seems to be an independent and unfavourable predictor of the lack of obtaining pCR1 pathological response 2. In the multivariate analysis, the obesity was a significant independent factor related to shorter OS.
