[Comparative study on gemcitabine plus cisplatin and vinorelbine plus ifosfamide plus cisplatin combined chemotherapy in the treatment of advanced non-small cell lung cancer].
BACKGROUND
To compare the effect and toxicity between gemcitabine and cisplatin (GP) with vinorelbine, ifosfamide and cisplatin (NIP) combined chemotherapy in the treatment of patients with advanced non-small cell lung cancer (NSCLC).


METHODS
Eighty patients received either gemcitabine 1 000 mg/m² on days 1, 8, or 15 plus cisplatin 70-80 mg/m² on day 1, or vinorelbine 25 mg/m² on days 1, 8, ifosfamide 1.2 g/m² on days 1-4 plus cisplatin 70-80 mg/m² on day 1, every 28 days as a cycle.


RESULTS
The objective response rate was 40.0% in GP goup, compared with 52.5% in NIP group (P > 0.05). Median survival time of GP and NIP groups was 13.68 and 15.34 months respectively, and 1-year survival rates were 54.29% and 59.46% respectively (P > 0.05). Leukopenia at grade III+IV was significantly lower in GP arm (27.5%) than that in NIP arm (55.0%) (P < 0.05). Non-hematological toxicities were less frequent in GP group than those in NIP group (P < 0.05).


CONCLUSIONS
Although the response rate tends to be higher in three-drug than in two-drug combined chemotherapy, but no significant difference is observed. Three-drug combinations often result in more toxicities. Two-drug combination GP may be the standard protocol for chemotherapy of advanced NSCLC. Three-drug combination NIP should be given to young patients with good performance status.
