About

The purpose of this study is to determine whether neoadjuvant radiation therapy is effective in improving local-regional control and to explore predictors of response to treatment in inoperable breast cancer patients after 2-6 courses of neoadjuvant chemotherapy.

Full description

RATIONALE: The optimal management of patients with locally advanced breast cancer(LABC) remains unknown. It is currently accepted that the administration of radiation therapy prior to surgery might result in higher surgery rate or improvement of clinical outcomes.

OUTLINE: This is a prospective phase II study. The purpose is to evaluate the effectiveness of neoadjuvant radiotherapy in combination with chemotherapy. The primary objective in this study is to assess clinical outcomes of these patients. A secondary objective in this study is to identify biomarkers and imaging parameters that can be used as early predictors of treatment response in women with locally advanced breast cancer. Fresh tumor tissue or fresh peripheral blood should be collected as the test sample and stored before treatment. Ultrasound spectroscopy including shear wave elastography parameters should be done before and after treatment.
