RESUMEN
<p><b>BACKGROUND</b>To evaluate three new chemotherapeutic regimens for non-small cell lung cancer (NSCLC) by pharmacoeconomic analysis in guiding rational use of drugs.</p><p><b>METHODS</b>One hundred and one cases of NSCLC in clinic stage III or IV were treated by one of the three chemotherapeutic schemes-PC: paclitaxel (135mg/m²,d1)+DDP; TC: docetetaxel (75mg/m²,d1)+DDP; VC: vinorelbine (25mg/m²,d1 and d8)+DDP, DDP were given at 80mg/m² in 3 groups. Pharmacoeconomic cost-effectiveness analysis was used to compare the efficacy of the three regimens.</p><p><b>RESULTS</b>The response rate was 46.9%, 48.6% and 47.1% and median survival duration was 7.8, 7.5 and 7.6 months for PC, TC and VC regimen respectively, with 1-year survival rate of 37.5%, 37.1% and 38.2% respectively. There was remarkable difference in the response rate and median survival duration between PC and TC, but no statistical difference was observed between PC and VC. There was no statistical difference in 1-year survival rate among the three regimens. The average cost of one patient for one therapeutic cycle was RMB 15840.5, 15831.1 and 9401.8 Yuan respectively. Escalation of 1% of response rate costed RMB 337.75, 325.74 and 199.61 Yuan respectively. Prolongation of 1 month of median survival duration costed RMB 2030.83, 2110.97 and 1237.08 Yuan respectively. Escalation of 1% of one year survival rate costed RMB 422.41 , 426.71 and 246.12 Yuan respectively.</p><p><b>CONCLUSIONS</b>Among these three new chemotherapeutic regimens for the advanced patients with NSCLC, the expenditure of VC is much cheaper than PC and TC. The cost effectiveness of VC is the lowest among the three regimens.</p>
