[Analysis of the risk factors for severe neutropenia in advanced non-small cell lung cancer after the first course of chemotherapy with third-generation agents].

  We retrospectively evaluated clinical data before therapy to determine the risk factors for severe neutropenia in advanced non-small-cell lung cancer (NSCLC) patients treated with third-generation agents. We analyzed 100 patients who received such agents (paclitaxel, docetaxel, gemcitabine, irinotecan, or vinorelbine) for advanced NSCLC. The endpoint of the survey was the occurrence of severe neutropenia (grade 4).
