Metastatic Colorectal Cancer: A Systematic Review of the Value of Current Therapies

To evaluate, from a US payer perspective, the cost-effectiveness of treatment strategies for metastatic colorectal cancer (mCRC), we performed a systematic review of published cost-effectiveness analyses. We identified 14 papers that fulfilled our search criteria and revealed varying levels of value among current treatment strategies. Older agents such as 5-fluorouracil, irinotecan, and oxaliplatin provide high-value treatments. More modern agents targeting the EGFR or VEGF pathways, such as bevacizumab, cetuximab, and panitumumab, do not appear to be cost-effective treatments at their current costs. The analytical methods used within the papers varied widely, and this variation likely plays a significant role in the heterogeneity in incremental cost-effectiveness ratios. The cost-effectiveness of current treatment strategies for mCRC is highly variable. Drugs recently approved by the US Food and Drug Administration for mCRC are not cost-effective, and this is primarily driven by high drug costs.
