Abstract

Objective: To evaluate the efficacy and safety of nimotuzumab combined with gemcitabine and cisplatin as second-line chemotherapy for advanced non-small-cell lung cancer (NSCLC) and to investigate the association of the status of KRAS gene mutation and epidermal growth factor receptor (EGFR) genotype with clinical outcome. Methods: Twenty-eight patients with advanced NSCLC were enrolled in this single center, uncontrolled pilot clinical study. All the patients developed drug resistance or disease progression after first-line chemotherapy of either a docetaxel + cisplatin regimen or a vinorelbine + cisplatin regimen and then received nimotuzumab combined with gemcitabine and cisplatin as second-line chemotherapy. Eight cases were stage IIIB and 20 were stage IV. An i.v. dosage regimen of 200mg of nimotuzumab was given as a single dose, injected into the patient at days 1, 8 and 15; i.v. gemcitabine was injected at a dose of 1000mg/m 2 at days 1 and 8 and cisplatin (25mg/m 2 i.v.) at days 1, 2 and 3. Each patient received four or more therapeutic cycles. The efficacy and toxic reactions were evaluated, as well as time to progression and overall survival. Results: In total, 28 patients with advanced NSCLC received 101 therapeutic cycles. The mean cycle number was 3.6. Median time to progression was 4.9 (2.5-6.5) months; median overall survival and 1-year survival rate were 9.8 months and 48.5%, respectively. There was one case of complete response, six cases of partial response, 11 cases of stable disease and 10 cases of progressive disease. Response rate was 25%, and clinical benefit rate was 64.3%. Major toxic reactions were bone marrow suppression and gastrointestinal reaction. Only one patient developed grade I acneiform eruption. Conclusion: Nimotuzumab combined with gemcitabine and cisplatin as second-line chemotherapy for advanced NSCLC was active and well-tolerated in this setting. Patients with EGFR amplification and KRAS gene wild type had a better prognosis. Prospective, randomized, controlled, large-scale clinical studies are needed to confirm the results.
