Cost-effectiveness of neoadjuvant multimodal therapy in patients with esophageal adenocarcinoma.

We conducted an incremental cost-effectiveness analysis to evaluate an adjuvant multimodal therapy (chemotherapy + radiotherapy) in patients with esophageal adenocarcinoma undergoing surgery. We utilized the clinical data of a published controlled trial comparing preoperative chemotherapy + radiotherapy versus surgery alone. Information on costs was derived from local data and verified against reported values. Multimodal treatment was found to improve life expectancy by 196.9 discounted years every 100 subjects (survival gain of about 2 years per patient). Costs of this neoadjuvant therapy were estimated as $780,010 per 100 patients. Our cost-effectiveness analysis showed that the cost per life year gained was $3,961 for the multimodal therapy in comparison with surgery alone. The pharmacoeconomic profile of this therapeutic modality compares favorably with previous economic data calculated for other types of health care intervention.
