Abstract

BACKGROUND:

To explore a new schedule of gemcitabine-cisplatin (GP) combination therapy using two different cisplatin doses in patients with advanced non-small-cell lung cancer (NSCLC).

PATIENTS AND METHODS:

From May to December 1997, 92 chemonaive patients entered the study and 88 (28 with locally advanced and 60 with disseminated NSCLC) were evaluable for response and toxicity (45 in arm A and 43 in arm B). Patients were randomly assigned to arm A or arm B. Gemcitabine 1000 mg/m2 was given on days 1-8 plus cisplatin 100 mg/m2 in arm A and cisplatin 70 mg/m2 in arm B on day 2 of every 21-day cycle.

RESULTS:

The overall response rates in arms A and B were 42% (95% confidence interval (CI): 27.8%-56.7%) and 47% (95% CI: 31.6%-61.5%), respectively. Median duration of response was 9.7 months (range 1.8 to 30.9 months; 13.1 and 9.5 months for arm A and B, respectively), and median survival was 12 months (range 0.2 to 31.1 months; 15.4 and 11.5 months for arm A and B, respectively). Major WHO grade 3-4 toxicities in arm A vs. arm B included: thrombocytopenia (23% vs. 17% of courses), leukopenia (15%, vs. 4% of courses), anemia (7% vs. 6% of courses), and nausea-vomiting (20% vs. 7% of patients). Grade 1-2 nephrotoxicity occurred in 20% of patients in arm A and in 7% of patients in arm B, with one grade 4 episode in arm A. Six patients discontinued treatment because of toxicities, 5 in arm A and I in arm B.

CONCLUSIONS:

Results of this trial indicate that both schedules are feasible and active, with a milder toxicity in the arm with the lower cisplatin dose.
