Economics of the clinical management of lung cancer in France: an analysis using a Markov model.

Abstract

To evaluate, according to the histologic type and initial stage, the mean cost (MC) of managing patients with lung cancer and the costs of the different management phases. A Markov approach was used to model these costs, based on the management of a representative nation-wide sample of 428 patients with newly diagnosed lung cancer. The 18-month MC ranged from US$ 20 691 (95% CI: 5777–50 380 for diffuse non-small-cell lung cancer (NSCLC) to US$ 31 833 (95% CI: 15 866–64 455) for localised small-cell lung cancer (SCLC); first-line treatment costs ranged from 33.8% of MC for medically inoperable localised NSCLC to 74.6% for diffuse SCLC; second- or third-line treatment costs ranged from 7.8% of MC for surgically treated localised NSCLC to 32% for locally advanced NSCLC; and the cost of palliative care ranged from 9.1% of MC for locally advanced NSCLC to 39.9% for medically inoperable localised NSCLC. The cost of first-line chemotherapy and the percentage of actively treated patients impacted more on MC than did the cost of second- or third-line chemotherapy regimens or the cost of palliative care. In conclusion, this model provides a robust economic analysis of the cost of lung cancer management, and will be useful for assessing the economic consequences of future changes in patient management.
