Short-term complications of intra-operative radiotherapy for early breast cancer

Abstract

Introduction: IORT is becoming an accepted radiotherapy technique for treatment of early breast cancer. Data regarding the early complications of breast IORT are lacking.

Objectives: Assess the nature and risk factors for early complications of breast conserving surgery (BCS) and intraoperative radiotherapy (IORT) with INTRABEAM®.

Methods: IORT with INTRABEAM® was administered to breast cancer patients in Carmel Medical Center as part of an institutional clinical registry project. Three hundred and ninety five patients treated during 2006-2013 were included. Clinical and treatment data and data regarding complications documented within 1 year of surgery were collected. The association between clinical and treatment variables and risk of complications was assessed.

Results: Complications were documented in 108 (27.3%) of patients. Grade III or IV complications were found in 5% of patients. Infections were diagnosed in 43 (10.8%) patients, seroma in 40 (10.1%), wound dehiscence in 32 (8.1%), and bleeding and hematomas in 11(2.8%). Two patients had a small size skin necrosis. Sixteen patients with a seroma had a secondary complication. All complications resolved. Diabetes mellitus and use of anticoagulants were associated with an increased risk of wound dehiscence and bleeding, respectively.

Conclusions: IORT for breast cancer is safe in appropriately selected patients. Careful surgical technique and postoperative care is prudent. J. Surg. Oncol. 2016;113:370-373. © 2016 Wiley Periodicals, Inc.
