Oligorecurrence Non-small Cell Lung Cancer After Failure of First-Line Chemotherapy: Computed Tomography-Guided I Seed Implantation vs. Second-Line Chemotherapy.

To compare the efficacy and safety of computed tomography (CT)-guided I seed implantation with second-line chemotherapy in treatment of oligorecurrence non-small cell lung cancer after failure of first-line chemotherapy. Data of oligorecurrence non-small cell lung cancer patients after failure of first-line chemotherapy at two institutions were retrospectively reviewed from January 2013 to July 2018. A total of 53 patients who received the treatment of I seed implantation or second-line chemotherapy were eligible for this study.
