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.
目的
评估采用传统细胞毒性方案和辅助单克隆抗体（mAb）治疗的转移性结直肠癌患者的成本和生存估计。
方法
采用回顾性随机病例系列和疾病成本分析。从东南欧最大的大学军事医院档案中随机选取62例转移性结直肠癌病例。
结果
mAb使生存期延长6个月（p = 0.581）。传统方案的总直接医疗成本为5137欧元（95%CI：3758欧元 - 6517欧元），而基于mAb的治疗组为22113欧元（95%CI：16201欧元 - 28025欧元）。mAb每延长一年生命的增量成本效果比为32108欧元，是塞尔维亚非正式支付意愿阈值的三倍。
结论
mAb辅助方案对5年生存率有适度的积极影响。成本由靶向生物制剂驱动，但在其他方面，mAb治疗组的护理成本也显著更高。应采用更具选择性的处方和报销标准，以提高靶向肿瘤药物的成本效益。
