Systemic Therapy Combined with Locoregional Therapy Improved Survival in Oligometastatic Breast Cancer: A Single-Center Retrospective Cohort Study

Figure 3

Kaplan-Meier survival for overall survival (OS) according to the treatment approach. Patients who received both systemic and locoregional therapies had significantly longer OS than those who received systemic therapy alone. The median OS was 39.8, 70.5, and 26.7 months in the ST to LRT, LRT to ST, and ST alone groups, respectively. ST to LRT: systemic therapy followed by locoregional therapy; LRT to ST: locoregional therapy followed by systemic therapy; ST: systemic therapy.
