    Abstract:
    We investigated the possibility of shortening the interval between courses of the commonly prescribed 28-day MVP (mitomycin C, vindesine, and cisplatin) regimen in patients with non-small-cell lung cancer (NSCLC). We conducted a nonrandomized phase II study using recombinant human granulocyte colony-stimulating factor (G-CSF, Chugai) to explore the possibility of shortening the cycle length to 21 days and compared the results with those obtained in historical controls who had received the standard 28-day regimen. A total of 40 patients, 37 of whom were evaluable, were entered in the 21-day treatment group of the trial and were compared with 38 historical controls who had received standard 28-day cycles of MVP at our institution. Patients in the 21-day group received mitomycin C at 8 mg/m2 on day 1, vindesine at 3 mg/m2 on days 1 and 8, and cisplatin at 80 mg/m2 on day 1, with the schedule being repeated every 21 days. Controls had received the same regimen, albeit at 28-day intervals. G-CSF was given s.c. to the patients in the 21-day group at a daily dose of 2 micrograms/kg from day 2 to day 21 of every MVP cycle. The administration of G-CSF to these patients accelerated neutrophil recovery as compared with that observed in the historical controls. Significant differences were found between the two groups in terms of mean neutrophil nadirs (2666/microliters in the first cycle and 1369/microliters in the second for the G-CSF group vs 416/microliters in the first cycle and 685/microliters in the second cycle for the control group; P < 0.0001) and the mean duration of neutropenia (< or = 1000/microliters; 1.0 day in the first cycle and 1.7 days in the second for the G-CSF group vs 8.0 days in the first cycle and 6.9 days in the second for the control group; P < 0.0001). This enabled 32 (86%) of 37 patients in the G-CSF group to complete > or = 2 cycles on schedule. In 10 patients, the bone marrow aspirates taken after G-CSF administration showed increases in band neutrophil and myelocyte percentages. In conclusion, MVP treatment of patients with NSCLC at 21-day intervals is possible with the support of G-CSF.
