“Objectives: To characterize the incidence of postoperative complications in women with breast cancer classification T1 and T2N0M0 diagnosed and treated at the National Cancer Institute (INCA) between 2007-2009 according to axillary surgery (sentinel lymph node biopsy –SLNB and axillary lymphadenectomy – AL). Methods: Observational study of a cohort of 933 women with clinical diagnosis T1-T2N0M0 treated at Cancer Hospital III of the National Cancer Institute (HC-III/INCA) in 2007-2009, and followed by a period of 60 months. Data collection was based on analysis of the Hospital Registry Cancer, the physical and/or electronic records of patients – HCIII/INCA and clinical evaluation form the Physical Therapy Service of the HC-III/INCA. Among the evaluated information included sociodemographic, clinical, lifestyle habits, implemented treatments and outcome variables. The outcome variables were those related to post-surgical complications in the affected upper limb and surgical wound. Results: The cohort was divided into 683 women undergoing SLNB, 144 to SLNB followed by AL and 106 patients received AL directly. Women undergoing SLNB estimate showed a significantly lower risk of postoperative complications when compared to women undergoing AL (axillary web syndrome: 6,0% vs 22,5%; OR: 0,37 IC95% 0,21 – 0,63; paresthesia: 45,2% vs 89,8%; OR: 0,10 IC95% 0,06 – 0,16; winged scapula: 9,1% vs 50,0%; OR: 0,12 IC95% 0,08 – 0,18; seroma: 28,5% vs 69,4%; OR: 0,32 IC95% 0,22 – 0,47; wound infection: 3,8% vs 12,9%; OR: 0,38 IC95% 0,22 – 0,70; lymphedema: 3,2% vs 56,7%; HR: 0,23 IC95% 0,11 – 0,48). Conclusion: SLNB technique proved to be an independent protective factor for complications such as seroma, wound infection, axillary web syndrome, paresthesia, winged scapula and lymphedema compared to AL.
