Five-year survival and costs of care in metastatic colorectal cancer: conventional versus monoclonal antibody-based treatment protocols

Research output: Contribution to journalArticle

Abstract

AIM: To evaluate the costs and survival estimates of metastatic colorectal carcinoma patients treated with conventional cytostatic protocols and adjuvant monoclonal antibodies (mAbs).

METHODS: Retrospective randomized case series and cost-of-illness analysis was used. Metastatic colorectal carcinoma cases (62) were randomly selected from the archive of the largest university military hospital in Southeastern Europe.

RESULTS: A 6-month longer survival was attributed to mAbs (p = 0.581). Conventional protocols incurred € 5137 (95% CI: € 3758-€ 6517) versus € 22,113 (95% CI: € 16,201-€ 28,025) total direct medical costs in mAb-based group. ICER of € 32,108 per life year gained attributable to mAbs three-fold exceeded informal willingness to pay threshold of Serbia.

CONCLUSION: mAbs adjuvant protocols had modest positive impact on 5-year survival rates. Costs were driven by targeted biologicals, but significantly higher costs of care were recorded in mAb-treated group in other domains, as well. More selective prescription and reimbursement criteria should be applied to increase cost-effectiveness of targeted oncology agents.
