title: Comparison of docetaxel/cisplatin to docetaxel/gemcitabine as first-line treatment of advanced non-small cell lung cancer: early results of a randomized trial.
abstract: The study compares docetaxel plus cisplatin (DC) and docetaxel plus gemcitabine (DG) regimens for the treatment of advanced non-small cell lung cancer (NSCLC). Patients were randomized to receive either the DC or the DG combination. They were stratified according to age, performance status (PS) and stage of disease. Three hundred seventeen patients entered the study. Of them, 162 received the DC regimen and 155 the DG regimen. There were no differences in the patients' characteristics between the two study arms. Preliminary analysis included 132 evaluable patients in the DC arm and 114 in the DG arm. Three complete responses (CR) (2.3%) and 39 partial responses (PR) (30%) were documented in the DC arm (response rate (RR) 32.3%; 95% CI 23.87-39.76%), whereas 1 CR (0.9%) and 38 PR (33%) were documented in the DG arm (RR: 33.9%; 95% CI 25.5-42.92%). No differences in the RR, response duration, time to tumor progression, overall survival and 1-year survival were observed between the two groups. Regarding toxicity, there were no significant differences in grade 3-4 anaemia and thrombocytopenia between the two arms. However, grade 3-4 neutropenia occurred in 40 patients (33%) treated with the DC regimen and in 31 patients (22%) treated with the DG regimen (P=0.01). Twenty-four (16%) patients in the DC arm and 20 (14%) in the DG arm developed febrile neutropenia. There was one death due to sepsis in each arm. Non-haematological toxicity was mild and equal in the two arms, with the exception of grade 3-4 nausea and diarrhoea, which were more frequent in the DC arm. In conclusion, preliminary results showed that the DG regimen was as effective as the DC regimen. The toxicity profile of the DG combination was relatively milder. Hence, cisplatin cannot be considered longer as a mandatory component of chemotherapy against NSCLC.
