[Efficacy of MVP chemotherapy combined with concurrent radiotherapy for advanced non-small cell lung cancer].

Background: To observe the effects of MVP chemotherapy combined with concurrent radiotherapy for stage IIIB-IV non-small cell lung cancer.

Methods: Sixty-two patients with stage IIIB-IV non-small cell lung cancer were randomized into two groups, concurrent radiochemotherapy group and MVP che-motherapy group. All patients in two groups were treated with MVP regimen (mitomycin C 6 mg/m² on day 1, vindesine 2 mg/m² on days 1, 8, and cisplatin 80-100 mg/m²). Patients in concurrent radiochemotherapy group received concurrent radiotherapy (46-56 Gy in 5-6 weeks).

Results: All patients received 2-4 cycles of MVP chemotherapy. The response rate was 48.4% and 19.4% in concurrent radiochemotherapy group and MVP group respectively (P < 0.05), the 1-year survival rate was 54.8% and 22.6% respectively (P < 0.05), median time to progression was 8 months and 4 months respectively (P < 0.05), and median survival duration was 10 months and 6 months respectively (P < 0.05). Incidence of grade II-III leukopenia in concurrent radiochemotherapy group was remarkably higher than those in MVP group..

Conclusions: The results show that efficacy of MVP chemotherapy combined with concurrent radiotherapy is significantly higher than that of MVP chemotherapy alone for advanced non-small cell lung cancer.
