Cost-utility analysis of chemotherapy in symptomatic advanced nonsmall cell lung cancer.

When using chemotherapy in patients with a short life expectancy, outcomes such as symptom improvement or clinical benefit receive increasing attention. Outcomes of subjective benefit to the patient can be rated as a utility in order to perform health economic analyses and comparisons with other treatment conditions. A cost-utility analysis has been performed alongside a prospective randomised clinical trial comparing single agent gemcitabine to cisplatin-based chemotherapy in symptomatic advanced nonsmall cell lung cancer patients. Global quality of life as well as resource utilisation data were collected during first-line chemotherapy for both treatment arms. Incremental costs, utilities and cost-utility ratio were calculated. Per patient, an incremental cost of 1,522 was obtained for gemcitabine compared to cisplatin-vindesine, mainly as a consequence of the direct cost of the cytotoxic drugs. When combined with utilities, this resulted in an incremental cost-utility ratio for gemcitabine of 13,836 per quality-adjusted life year gained. In conclusion, although the least expensive strategy is cisplatin-vindesine, the greater clinical benefit of gemcitabine, resulting in an acceptable incremental cost-utility ratio as compared with other healthcare interventions, balances its higher cost. The gains in subjective outcome achieved with palliative chemotherapy are critical from both a clinical and a health economic point of view.

Vindesine-ifosfamide-platinum (VIP) induction chemotherapy in surgically staged IIIA-N2 non-small-cell lung cancer: a prospective study. Leuven Lung Cancer Group.

PURPOSE: In the pioneer data from the Memorial-Sloan-Kettering group, preoperative mitomycin-C-vindesine-platinum (MVP) induction chemotherapy in N2-NSCLC was accompanied with substantial pulmonary toxicity. In this study, the efficacy and toxicity of three-drug VIP induction chemotherapy, the pathologic response in resection specimens, the early survival and relapse patterns are examined. PATIENTS AND METHODS: Between June 1995 and March 1997, 39 consecutive patients with pathology proven N2-NSCLC were treated with three cycles of VIP induction, followed by definitive locoregional treatment (resection and mediastinal dissection or radical radiotherapy). Several patients had unfavorable prognostic characteristics with respect to clinical and biological findings, tumor location and bulk of disease. RESULTS: The response rate to chemotherapy was 59% (95% Confidence Interval 34-75). Twenty-three responding patients had radical locoregional treatment: radical radiotherapy in four, resection in 19. Downstaging was present in nine of the 19 resection specimens, with two pathologic complete responses. The median survival time (MST) of all patients is 19 months, with a projected two-year survival of 49%. In patients responsive to chemotherapy who received definitive local treatment, the MST is not yet reached, and the projected two-year survival is 57%. Relapses were mainly distant, with isolated brain relapse as a disturbing finding. The main toxicity's were leukopenia and vomiting, but they were manageable. In contrast with MVP, no severe pulmonary toxicity occurred. CONCLUSIONS: VIP is a suitable induction regimen for N2-NSCLC, demonstrating a good activity and very acceptable toxicity.
