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.

To evaluate the efficacy of a three-drug regimen vs. a two-drug CDDP based combination in the treatment of NSCLC, we conducted a three-arm randomized parallel trial comparing (a) CDDP (120 mg/m2 day 1) + etoposide (100 mg/m2 days 1-3) every 3 weeks (PE--arm A); (b) CDDP (120 mg/m2 every 4 weeks) + mitomycin (8 mg/m2 days 1, 29, 71) + vindesine (3 mg/m2 days 1, 8, 15, 22 every 2 weeks) (MVP--arm B); and (c) CDDP (120 mg/m2 day 1) + mitomycin (6 mg/m2 day 1) + ifosfamide (3 g/m2 day 2) every 3 weeks (MIC--arm C). From May 1989 to April 1992, 393 consecutive previously untreated patients with NSCLC Stage IIIB and IV entered the trial; 373 were evaluable for survival and 360 for response. The response rate was significantly better for both the three-drug regimens compared with PE (Table 3). Logistic regression model showed a significantly better response in patients with a good P.S. and in Stage IIIB. Main toxicity consisted of myelosuppression: neutropenia Grade III-IV was recorded in 14% (arm A), 15% (arm B) and 21% (arm C). Thrombocytopenia Grade III-IV was worst in arm C: 10% vs. 5% (arm A) and 3% (arm B). Nephrotoxicity Grade III-IV was more common in arm C: 3.5%. Toxic deaths were 11 (3%: three in arm A, five in arm B, three in arm C). From our data, the three-drug containing regimens, MVP and MIC, appear more active than the two-drug combination PE in treatment of advanced NSCLC.

A prospective randomized study was conducted to determine the optimal schedule of rhG-CSF (recombinant human granulocyte colony-stimulating factor). A group of 33 lung cancer patients treated with MVP therapy (mitomycin, vindesine, and cisplatin) were randomly assigned to three groups: an early prophylaxis group in which rhG-CSF was initiated on day 2 of the MVP cycle; a late prophylaxis group in which rhG-CSF was initiated on day 8; and a therapeutic group in which rhG-CFS was initiated after the onset of neutropenia. Ten patients who had received MVP therapy without rhG-CSF were also analyzed as a no-support group. The incidence of neutropenia was 80% (16/20 courses) in the early prophylaxis group, 44% (8/18) in the late prophylaxis group, 94% (17/18) in the therapeutic group, and 94% (16/17) in the no-support group. The incidence of neutropenia in the late prophylaxis group was less than in the early prophylaxis group (P<0.05), the therapeutic group (P<0.01), and the no-support group (P<0.01). The late prophylactic rhG-CSF schedule was therefore more effective in countering neutropenia than either the early prophylactic or therapeutic schedule.

MVP chemotherapy (mitomycin C 8 mg m(-2), courses 1, 2, 4 and 6, vinblastine 6 mg m(-2), cisplatin 50 mg m(-2)) is an active low-toxicity regimen in non-small-cell lung cancer (NSCLC). Based on the single-agent activity of these agents in SCLC, we have conducted a phase II trial of MVP in SCLC. Fifty chemo-naive patients with SCLC were entered in this trial. There were 33 men and 17 women with median age 66 years (range 46-83 years); 18 patients had limited disease (LD) and 32 extensive disease (ED). WHO performance status (PS) was: three patients PS 0, 33 patients PS 1, ten patients PS 2, four patients PS 3. A maximum of six cycles was given in responding patients. On completion of chemotherapy, patients with LD obtaining complete response (CR)/good partial response (PR) received thoracic irradiation and those obtaining CR were offered entry into the ongoing MRC Prophylactic Cranial Irradiation Trial. The overall response was 79% with 17% CR and 62% PR. For LD patients, 38% obtained CR but for ED only one patient achieved CR. Median response duration for LD patients was 8 months and for ED patients 5 months. Median survival was 10 months for LD patients and 6 months for ED patients. There was complete resolution of symptoms in 24%, partial improvement in 68%, no change in 2% and progressive symptoms in 6%. As regards toxicity, 24% developed WHO grade 3/4 neutropenia, 16% grade 3/4 thrombocytopenia and 6% significant hair loss. Two patients died during the first week of treatment with neutropenic infection. Quality of life using the EORTC questionnaire (QLC-C30) with lung cancer module demonstrated significant improvements from baseline levels in emotional and cognitive functioning, global QOL, of pain, dyspnoea and cough. MVP, an effective palliative regimen for NSCLC, is also active against SCLC with low toxicity and merits comparison with more toxic conventional schedules.
