[Impact of the preservation of the branches of intercostobrachial nerve on the quality of life of patients operated for a breast cancer]. / Impact de la conservation des branches du nerf intercostobrachial sur la qualité de vie des patientes opérées pour un cancer du sein.

AIM: The aim of this study was to assess the impact of the preservation of the intercostobrachial nerve on the quality of life of patients operated for breast cancer. METHODS: This study was ancillary to cost comparison study of axillary sentinel lymph node detection and axillary lymphadenectomy in early breast cancer. It was a prospective multicenter, observational, non-randomized study. The quality of life was assessed using two questionnaires: QLQ-C30 and specific module QLQ-BR23 Surveys have been performed before initiation of surgery, one week, and 1 month, 8 months and 12 months after discharge from hospitalization for the first surgical procedure. RESULTS: Five hundred and seventy-eight patients with preservation of intercostobrachial nerve without axillary lymph node dissection (C- P+), 85 without preservation of nerve and axillary lymph node dissection (C+P-) and 57 with preservation of nerve and axillary lymph node dissection (C+P+) have been included in the study. The changing arm symptoms score was significantly different during follow-up between the three groups (P<0.001). This difference between the two groups C- P+ and C+P+ was significant clinically at one week [16.9, IC95%: 11.9 to 22 (P<0.01)], and persisted for up to 12 months [9.9, IC95%: 3.2 à16.6 (P=0.022)]. There was no difference between the group C+P- and C+P+. Results for physical functioning score were similar. CONCLUSION: Preservation of the intercostobral nerve is not associated with better quality of life. Only axillary lymph node dissection has an impact on quality of life.
