Background:The aim of this study was to assess long-term quality of life (QoL) over a period of 6 years in women with breast cancer (BC) who underwent sentinel lymph node biopsy (SLNB), axillary lymph node dissection (ALND), or SLNB followed by ALND.Methods:The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ)-C30 and the EORTC-QLQ-BR-23 questionnaires were used to assess QoL before surgery, just after surgery, 6, 12 and 72 months later. The longitudinal effect of surgical modalities on QoL was assessed with a mixed model analysis of variance for repeated measurements.Results:Five hundred and eighteen BC patients were initially included. The median follow-up was 6 years. During the follow-up, 61 patients died. None of the patients of the SLNB group developed lymphedema during follow-up and the relapse rate was similar in the different groups (P=0.62). Before surgery, global health status (P=0.52) and arm symptoms (BRAS) (P=0.99) QoL scores were similar whatever the surgical procedure. The BRAS score (P=0.0001) was better in the SLNB group 72 months after surgery. Moreover, during follow-up, patients treated with SLNB had lower arm symptoms scores than ALND patients and there was no difference for arm symptoms between patients treated with ALND and those treated with SLNB followed by complementary ALND.Conclusion:Long-term follow-up showed that SLNB was associated with less morbidity than ALND.

This population-based study aimed to describe the effects of neoadjuvant chemotherapy ( NC) on survival in breast cancer ( BC) patients in daily practice. BC patients treated with NC followed by surgery and radiotherapy, were retrospectively selected from 1982 to 2005 using the Côte d' Or BC registry. These patients were matched for the baseline AJCC ( American Joint Committee on Cancer) stage, age at diagnosis, date of diagnosis and oestrogens receptors status to those who had undergone surgery followed by adjuvant chemotherapy and radiotherapy. The prognostic effect of NC on survival in BC patients was assessed with relative survival ( RS) analyses. From 1982 to 2005, 210 patients with BC diagnosed in Côte d'Or were treated with NC followed by surgery and radiotherapy. For these patients, mean age at diagnosis was 50 ( SD = 11). The main tumour characteristics were clinical AJCC stage 3 (46%) and an advanced Scarff Bloom and Richardson ( SBR) stage (80%). Breast conserving surgery was performed in 84 patients (40%), 151 patients (72%) were treated with anthracyclines as the NC and the 5-year RS rate was 71%. Among these patients, 92 (37%) were matched. In this population, multivariate analyses showed that the use of NC did not independently influence RS: relative excess risk = 0.93 (0.50, 1.71).
