Radiotherapy for oligometastatic tumor improved the prognosis of patients with non-small cell lung cancer (NSCLC).

ABSTRACT:

Background

This study was conducted to investigate if radiotherapy improved the overall survival (OS) of patients with oligometastatic non-small cell lung cancer (NSCLC).

Methods

From January 2012 to August 2015, 323 NSCLC patients with distant metastasis were administered radiotherapy. Ninety-five patients with oligometastatic NSCLC who were sensitive to the initial chemotherapy were treated with radiotherapy for the residual lesions. Initial treatment consisted of four to six cycles of induction chemotherapy. If the patients responded to the initial treatment without developing new metastases, the residual sites were radiated at a total dose of 56-66 Gy, including the primary and metastatic sites. OS, progression-free survival, and sites of progression were assessed. The K
