Locoregional Recurrence After Neoadjuvant Versus Adjuvant Chemotherapy

Status Completed

Clinical Trial Summary

Neoadjuvant chemotherapy (NACT) for early-stage breast cancer is associated with an increased risk of locoregional recurrence (LRR). However, few studies have conducted subgroup analyses of patients with various molecular subtypes, which are one of the determinant factors for treatments. The aim of the study is to investigate whether the risk of LRR after NACT varies across tumor subtypes. The investigators retrospectively reviewed the medical records of female breast cancer patients who underwent breast-conserving surgery at three institutions between January 1, 2004, and Dec 31, 2018.
