Battleground Oligo: Role for Radiation and Sequencing Amidst an Evolving Systemic Landscape
摘要
Metastasis directed therapy (MDT) in the form of stereotactic ablative radiotherapy has been increasingly incorporated in the management of patients with limited systemic metastases. Oligometastatic breast cancer (OMBC) remains a biologically distinct entity within this landscape. Given the increasing prevalence of OMBC, we sought to synthesize the current evidence to guide clinical decision making for these patients.
Recent FindingsA number of recent studies have been conducted to refine the classification of OMBC, use of MDT, biological considerations, patient selection and clinical integration of focal therapy.
SummaryThe evidence reviewed illustrates the distinctive challenges and opportunities surrounding the use of MDT in the OMBC population. Use of MDT in patients with metachronous lesions may enable continuation of current systemic therapy. Patients with synchronous disease may represent a subgroup in which long term control is possible. Further study is required to identify those that benefit most from MDT.
