PURPOSE: Paclitaxel and docetaxel are two taxanes approved for the treatment of non-small-cell lung cancer (NSCLC). However, there is limited evidence regarding the efficacy of docetaxel in NSCLC previously treated with a paclitaxel-platinum doublet (PP). The aim of our study was to evaluate the response to docetaxel in NSCLC patients with prior PP treatment. METHODS: Patients with stage IV NSCLC treated with PP that presented disease progression and received docetaxel as second-line treatment were included. Demographics, clinical characteristics, EGFR mutation status, objective response (OR), overall survival (OS), progression-free survival (PFS), and PFS without chemotherapy after first line with PP were analyzed. RESULTS: Sixty-three patients were evaluated. Median age was 58 years, 54% of patients were women, 53% were never-smokers, and 39% had EGFR mutations. OR and median PFS for PP were 36.5% and 6.7 months, respectively. OR and median PFS for docetaxel were 19% and 3.8 months, respectively. Patients with EGFR mutations had better response to docetaxel compared with wild-type patients (26 vs. 17%, p = 0.028). However, only long PFS (>6 months) to first-line PP was independently associated with a higher OR [RR 6.3, 95% CI (1.03-38.4), p = 0.046], and longer PFS [0.49 (0.25-0.9)] and OS [0.2 (0.06-0.7), p = 0.008] to second-line docetaxel compared with patients with short PFS (≤6 months) to PP. CONCLUSIONS: Previous use of PP does not preclude a favorable response to docetaxel in NSCLC. Long PFS with PP may help select NSCLC patients who benefit from second-line docetaxel.
