Popis: We conducted a phase II trial to evaluate the safety and efficacy of weekly paclitaxel in patients with resistant or relapsed non-small cell lung cancer (NSCLC) treated with docetaxel and carboplatin. Thirty-two NSCLC patients at a median age of 58.0 years (range 33–75) were enrolled. The Eastern Cooperative Oncology Group performance status scores (0/1/2) were 18/9/5, respectively. The majority of patients had adenocarcinoma (84%) and stage IV disease (81%). The response rate for the first-line chemotherapy was 28%. Paclitaxel was administered at a dose of 80 mg/m2 as an intravenous infusion 60 min weekly for 6 consecutive weeks of an 8-week cycle. All patients were assessable for response and toxicity. The median number of cycles administered was two (range 1–8), and the overall response rate was 15.6%. The median survival time (MST) was 10.6 months (95% CI = 8.2–12.5), while the 1-year survival rate was 37.5%, and the median progression-free survival was 4.9 months (95% CI = 3.0–7.1). Hematological toxicities (grade 3 or 4) were observed in 15 patients (46.9%) with leukopenia, and in 4 (12.5%) with anemia. Non-hematological toxicity was generally mild, though grade 3 anorexia was observed in 3 patients (9.3%). No treatment-related deaths were observed. In conclusion, second-line weekly paclitaxel is effective in NSCLC patients treated with docetaxel plus carboplatin and is associated with a tolerable toxicity profile.
