BACKGROUND: To evaluate the efficiency of docetaxel as second line chemotherapy in patients with platinum-refractory non-small cell lung carcinoma (NSCLC).

PATIENTS AND METHODS: Fifty-two patients with locally advanced or metastatic NSCLC who had platinum-refractory disease (progressed through or within 3 months of completion of first line therapy) and an Eastern Cooperative Oncology Group performance (ECOG) status 0-2 were treated with second-line chemotherapy consisting of single agent docetaxel (100 mg/m(2), intravenously, on day 1 of a 21-day cycle). The median number of treatment cycles was 4 (2-6). Disease-free (DFS) and overall survival (OS), response rates and toxicity were evaluated.

RESULTS: The median progression-free survival of patients was 3 months (95% CI: 0.01-5.99) and overall survival was 7.2 months (95% CI: 2.2-9.5). One-year overall survival rate was 29%. Disease control (complete response, partial response, or stable disease) was achieved in 25 patients (48%) and overall response rate was 13% (7 patients). There were no complete responses. Seventeen patients (33%) had stable disease and twenty-seven patients (52%) had progressive disease. Age, gender, stage at diagnosis (IIIB vs. IV), performance status at initiation of second-line therapy (0-1 vs. 2) histopathological type (epidermoid vs. others), grade, LDH, albumin, weight loss were evaluated as prognostic factors; however, none of these had a significant affect on survivals. The protocol was well tolerated and there were no toxic deaths. Grade III-IV anemia was present in 8 patients (15%) and thrombopenia in 12 (23%) patients. The most frequent grade 3-4 toxicities were leucopenia (52%) and neutropenia (48%). Febril neutropenia occurred in 14 patients (26%). No patients experienced grade III-IV mucositis and diarrhea. Totally, the need of a dose reduction was about 25% and treatment delay (4-9 days) occurred in 5 patients (10%) and 7 patients (13%), respectively, because of toxicity.

CONCLUSIONS: Second-line chemotherapy with single-agent docetaxel offers a small but significant survival advantage with acceptable toxicity for patients with advanced NSCLC who have platinum-refractory disease.
