Oncologic Outcomes and Toxicities of Salvage Treatment in Patients With Locoregionally Recurrent Breast Cancer

Recruiting now

Conditions studied: Breast Cancer

In brief

The purpose of this study is to evaluate clinical outcomes and adverse events of salvage treatment for locoregional recurrence of breast cancer. The main questions it aims to answer are: * Clinical outcomes after salvage treatment for locoregional recurrence * Adverse events and quality of life after salvage treatment for locoregional recurrence * Patient characteristics and treatment specifics which are related to the clinical outcomes and/or adverse events * Molecular signature associated with treatment resistance Participants will be assessed by multi-dimensional methods during and after radiation therapy: * Assessment for the disease status (disease-free or recurrence) including physical and radiologic examination * Assessment for the adverse events according to CTCAE version 5.0 * Assessment for the molecular signature using residual tissue after pathologic diagnosis * Assessment for the quality of life using questionnaires (BREAST-Q)
