title: Subjective morbidity and quality of life after sentinel node biopsy and axillary lymph node dissection for breast cancer.
abstract: OBJECTIVE
  Sentinel node (SN) biopsy is a minimally invasive surgical method for axillary staging in patients with breast cancer. The aim of this study was to evaluate mid-term morbidity after SN biopsy and axillary lymph node (ALN) dissection in patients with breast cancer receiving breast-sparing treatment, and to determine its impact on quality of life (QOL).
  
  
  METHODS
  One hundred fifteen patients with breast cancer underwent breast-conserving treatment with SN biopsy alone (Group 1: n = 54), ALN dissection with or without SN biopsy (Group 2: n = 51), or SN biopsy followed by later ALN dissection (Group 3: n = 10).
  
  
  RESULTS
  The mean post-operative follow-up was 20.3 months (range: 10-31 months) in Group 1, 24.3 months (range: 10-33 months) in Group 2, and 19.1 months (range: 12-28 months) in Group 3. Arm-shoulder pain was reported by 21.2% of patients in Group 1, 52.9% in Group 2, and 60% in Group 3 (P = 0.002). An arm swelling sensation was reported by 0% of patients in Group 1, 21.6% in Group 2, and 10% in Group 3. Dysesthesias were reported by 5.7% of patients in Group 1, 51% in Group 2, and 50% in Group 3 (P < 0.001). The mean global QOL self-rating score was 7.6 in Group 1, 7.6 in Group 2, and 7.7 in Group 3 (no significant difference).
  
  
  CONCLUSIONS
  SN biopsy is associated with significantly lower mid-term morbidity than ALN dissection.
