Variations in cost for non-metastatic HER2- breast cancer (BC), non-small cell lung cancer (NSCLC), and colorectal cancer (CRC).
e18106 Background: We aim to quantify economic outcomes of the most commonly used chemotherapy regimens for BC, NSCLC, and CRC in a commercially insured population. Methods: This analysis used clinical data from a prior authorization program for chemotherapy regimens linked with administrative claims data from 6/1/2015 to 5/31/2016. Clinical data included cancer type, stage at diagnosis, and biomarkers. Eligible patients were commercially insured members with a prior authorization request for one of the most commonly used NCCN recommended regimens for BC, NSCLC and CRC. Outcomes, including total healthcare cost and cost of chemotherapy were tracked from first claim for chemotherapy until end of treatment due to discontinuation, death or change in treatment. Patients were censored at 5/31/2016 or end of enrollment. Results: There were 1612 BC, 237 NSCLC, and 386 CRC non-censored patients who received therapy during the study period. Mean (SD) total and monthly drug costs and total health care costs for the most common regimens by cancer are summarized in the table. Conclusions: The relative value of the most common therapies for BC, NSCLC, and CRC varied significantly depending on the metric used underscoring the importance of comparing total healthcare costs when assessing the value of therapies. Information on these and other regimens will increase as the database grows over time. [Table: see text]
