Does treatment at the time of locoregional failure of breast cancer alter prognosis?

Abstract

Locoregional recurrence (LRR) after therapy for early breast cancer is common. Patients with LRR can suffer local consequences such as bleeding, ulceration, pain and arm oedema or symptoms of metastases. Unlike existing treatment guidelines for primary tumours, both local (surgical and radiation) and systemic treatment recommendations are less well defined after LRR. The purpose of this review was to assess whether or not treatment at the time of locoregional failure ultimately alters a patient's prognosis. Unfortunately, the data from both retrospective and prospective studies are inconclusive and therefore the treatment of patients with LRR will continue to be recommended using guidelines similar to those for primary breast cancer. Future studies of factors predicting LRR and metastatic spread may allow better prognostication of patients with LRR which may in turn effect both local and systemic treatment decisions.
