ABSTRACT
OBJECTIVE: This phase III study was aimed at evaluating whether the addition of gemcitabine (G) to vinorelbine (V) could improve the survival and quality of life (QoL) of elderly patients with advanced NSCLC. PATIENTS AND METHODS: Patients with advanced NSCLC, aged >or=70 years, were randomly allocated to receive V 30 mg/m(2) on days 1 and 8 every 3 weeks or G 1200 mg/m(2) plus V 30 mg/m(2) on days 1 and 8 every 3 weeks. Survival was the main end point of the study. The estimated sample size was 120 patients per arm, but an interim analysis of survival was planned on the first 60 patients per arm. RESULTS: In May 1999, an interim analysis was performed with the survival data of the first 120 eligible patients (V(arm)=60, G+V(arm)=60). Forty-nine patients had stage IIIB disease and 71 patients stage IV disease, median potential follow-up of 14 months (range; 3-22), 93 patients had died (G+V(arm)=41, V(arm)=52). Median survival time (MST) was 29 weeks and projected 1-year survival was 30% in the G+V(arm); these values were 18 weeks and 13% in the V(arm). At multivariate Cox analysis, the risk of death in the G+V(arm) compared with V(arm) was 0.48 (95% C1=0.29-0.79; P<0.01). Combination therapy was also associated with a clear delay in symptom and QoL deterioration. The ORR was 22 and 15% in the G+V and V(arms), respectively. Toxicity was not irrelevant in both arms. CONCLUSIONS: G+V treatment is associated with a significantly better survival than V alone in elderly NSCLC patients. The magnitude of the difference justifies the early closure of the study. The G+V regimen is now the SICOG reference regimen in this type of patients.

The present study was aimed at defining the antitumour activity of the cisplatin-paclitaxel-topotecan (CPT) weekly administration with G-CSF support in chemo-naive SCLC patients with extensive disease (ED-SCLC). Chemonaive ED-SCLC patients received cisplatin 40 mg/m(2), paclitaxel 85 mg/m(2), and topotecan 2.25 mg/m(2)weekly, with G-CSF (5 microg/kg days 3-5) support, for a maximum of 12 weeks. 37 patients were treated, for a total of 348 cycles delivered. 8 complete responses (22%) and 22 partial responses (59%) were recorded, giving an 81% [95% CI = 65-92%] ORR. At a 13-month (range, 4-26) median follow-up, median progression-free and overall survival were 8 months and 12.5 months, with 1-year and 2-year projected survivals of 55% and 21%, respectively. No toxic deaths occurred. Grade 4 neutropenia and thrombocytopenia occurred in 6 and 3 patients, respectively. Only one case of neutropenic sepsis was recorded, while haemorrhagic thrombocytopenia was never observed. Diarrhoea, paraesthesias and fatigue were the main nonhaematologic toxicities being severe in 6, 2 and 10 patients, respectively. The weekly CPT combination with G-CSF support represents a well tolerated therapeutic approach in chemo-naive ED-SCLC patients. The activity rate seems at least similar to that achievable with the standard front-line approaches.
