Abstract
BACKGROUND
We conducted a phase I/II trial to assess the feasibility and activity of combination chemotherapy with etoposide, ifosfamide, cisplatin, and epirubicin in limited-stage (LS, stage I-IIIB) and extensive-stage (ES, stage IV) non-small-cell lung cancer (NSCLC). End-points were treatment-related morbidity and mortality, response rate, duration of response, and survival.
PATIENTS AND METHODS
Chemotherapy followed by granulocyte colony-stimulating factor was given at a dose of etoposide (500 mg/m2), ifosfamide (4000 mg/m2), cisplatin (50 mg/m2), and epirubicin (50 mg/m2) (VIP-E) to 107 patients with NSCLC. Twenty-five patients with qualifying responses proceeded to high-dose chemotherapy with autologous peripheral blood stem cell transplantation after etoposide (1500 mg/m2), ifosfamide (12,000 mg/m2), carboplatin (750 mg/m2) and epirubicin (150 mg/m2) (VIC-E) conditioning. RESULTS OF CONVENTIONAL-DOSE VIP-E: 35 of 102 (34%) evaluable patients responded (2 CR's, 33 PR's), 33/102 patients (33%) showed no change (NC); the remainder of patients progressed with therapy (PD). Objective response rate was 68% (4% CR, 64% PR) in LS-NSCLC and 23% (1.4% CR, 21.4% PR) in ES-NSCLC. Median duration of survival was 13 months in LS-NSCLC and 5.5 months in ES-NSCLC. Two-year survival was 26% in LS and 2% in ES-NSCLC. RESULTS OF HIGH-DOSE VIC-E: 23 of 24 evaluable patients improved or maintained prior responses (92%), I patient showed NC. Treatment mortality was 4%. Median duration of survival was 17 months in LS-NSCLC and 10 months in ES-NSCLC. Two-year survival was 30% in LS and 8% in ES-NSCLC.
CONCLUSION
Response-rates and survival after conventional-dose VIP-E chemotherapy are comparable to other published trials of combination chemotherapy in NSCLC. Toxicity and mortality is acceptable in limited stage, but unacceptably high in extensive stage NSCLC. Although better response-rates were achieved in the high-dose arm, they did not translate into improved survival. Most stage IV NSCLC-patients will neither benefit from VIP-E conventional dose, nor from VIC-E high dose chemotherapy. Whether selected LS-patients with partial or complete responses to VIP-E induction chemotherapy could benefit from dose intensification in an adjuvant or neo-adjuvant setting remains to be determined.
