Prognostic factors and risk stratification for survival in oligometastatic colorectal cancer treated with stereotactic body radiotherapy.

ABSTRACT:

Purpose

This study aimed to evaluate treatment outcomes with associated prognostic factors, and to guide treatment strategies in colorectal cancer patients with oligometastatic disease (OMD) treated with stereotactic body radiotherapy (SBRT).

Materials and methods

This retrospective study included 74 colorectal cancer patients who received SBRT for 113 lesions (88 lung, 19 liver, and 6 lymph node). Each OMD was considered a separate case for patients repeatedly diagnosed with OMD. The log-rank test and Cox proportional hazards model were used to assess prognostic factors for progression-free survival (PFS).

Results

A total of 84 cases were analyzed. The median follow-up period was 32.2 months (range, 8.2 to 89.3 months). The 2-year PFS, widespread failure-free surviva
