Abstract

Salvage mastectomy is currently considered the standard of care for ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery (BCS) and postoperative radiotherapy (RT). Alternative treatment options for these patients, such as a second BCS followed by repeated RT, have been suggested. The panel of the Italian Association of Radiotherapy and Clinical Oncology developed clinical recommendations for second BCS followed by re-irradiation over mastectomy alone for women with IBTR using the Grades of Recommendation, Assessment, Development, and Evaluation methodology and the evidence to decision framework. The following outcomes were identified by the panel: locoregional control, metastasis-free survival, overall survival, and cancer-specific survival; acute and late toxicity, specific late toxicity, second locoregional tumor, and death related to treatment. An Embase and PubMed literature search was performed by two independent authors. Five retrospective observational studies were eligible for inclusion in the present analysis. According to the reports in the literature and our analysis, the advantages of second quadrantectomy and re-irradiation (re-QUART) outweigh its side effects, with overall good rates of survival and adequate toxicity without increasing costs. Given the very low level of evidence, the panel stated that a second BCS plus re-irradiation can be considered as an alternative to salvage mastectomy for selected patients with IBTR.
