Despite growing evidence that patients with advanced non–small-cell lung cancer have improved survival and better symptom control with modern systemic therapy, there is still resistance to the use of chemotherapy because

Le Chevalier and colleagues have reported results of a randomized controlled clinical trial comparing vinorelbine alone, versus vinorelbine combined with cisplatin, versus standard treatment consisting of vindesine and cisplatin in the treatment of patients with advanced non-small-cell lung cancer (NSCLC). Data on survival in the three study arms and estimates of the resources used to treat these patients were extracted from the publication and inserted into Statistics Canada’s POpulation HEalth Model (POHEM).

The POpulation HEalth Model (POHEM) lung cancer microsimulation model has provided a useful framework for calculating the cost of managing individual cases of lung cancer in Canada by stage, cell type, and treatment modality, as well as the total economic burden of managing all cases of lung cancer diagnosed in Canada. These data allow an estimation of the overall cost effectiveness of lung cancer therapy. The model also provides a framework for evaluating the cost effectiveness of new therapeutic strategies, such as combined modality therapy for stage III disease or new chemotherapy drugs for stage IV disease. By expressing the cost of lung cancer treatment as cost of life-years gained, such analyses allows useful comparisons of the cost effectiveness of these treatments with those of other costly but accepted medical therapies.
