Receiving cancer treatment at a non–National Cancer Institute (NCI)-designated Comprehensive Cancer Center was associated with higher drug costs, a cohort study found. Recently reported in The Oncologist, the findings suggest that higher-cost cancer treatments may be more common in nonacademic settings compared with academic settings.1

The study included adult patients younger than 65 years who had stage IV colorectal cancer, stage IV lung adenocarcinoma, or stage II to stage IV head and neck cancer that was diagnosed between 2004 and 2011 in North Carolina. Data were gathered from Medicaid and commercial insurance claims linked to the North Carolina Central Cancer Registry.

The study researchers defined treatment patients received as either low-cost or high-cost. Generally, the difference between a low-cost and high-cost treatment was the addition of a monoclonal antibody. For example, for stage IV colorectal cancer, FOLFOX and FOLFIRI were considered low-cost selections, while these regimens plus a monoclonal antibody, such as bevacizumab, were considered high-cost options.

A total of 800 patients were included in the study. The majority (79.6%) received care in a non–NCI-designated setting, and the study population included roughly equal proportions of each tumor type: colorectal cancer (31.9%), head-and-neck cancer (38.8%), and lung cancer (29.4%).

“Nonwhite race was more common among non-NCI patients (24.5% vs 16.6%), as was Medicaid insurance (28.4% vs 16.6%),” the authors wrote.

An adjusted analysis revealed that a higher proportion of patients who were treated in non–NCI-designated settings received high-cost treatment compared with patients who were treated in NCI-designated settings (35.8% vs 26.2%; prevalence difference, 9.6%; 95% CI, −0.1% to 18.7%), although differences were not statistically significant within the 3 cancer subgroups studied.

“Use of higher-cost cancer treatments may be more common in non-NCI than NCI settings,” the study authors wrote in conclusion. “This may reflect differential implementation of clinical evidence, local practice variation, or possibly a response to the reimbursement incentives presented by chemotherapy billing.”
