Official Title: Local Therapy for Hormone Receptor-positive Oligometastatic Breast Cancer - a Phase II Randomized Trial
Study ID: NCT04698252
Brief Summary: Randomized phase 2 trial to evaluate the efficacy of local therapy for oligometastasis from ER/PR-positive breast cancer. The study hypothesis is that local therapy in addition to systemic therapy improves progression-free survival in comparison with systemic therapy alone.
Detailed Description: Patients with estrogen receptor/ progesterone receptor-positive oligometastatic breast cancer with disease controlled after at least six months of systemic therapy will be enrolled in the study. Patients will be randomized to receive local therapy for oligometastatic sites in addition to systemic therapy or systemic therapy alone. Local therapy strategies will include surgery, radiotherapy, and radiofrequency ablation.
