Health expenditures and financial burden among patients with major gastrointestinal cancers relative to other common cancers in the United States.

Background: Gastrointestinal cancers contribute substantially to the cost of health care. We sought to quantify and compare the financial burden associated with treatment of gastrointestinal cancers versus other common nongastrointestinal cancers.

Methods: The Medical Expenditure Panel Survey from 2006 to 2015 was used to identify individuals with gastrointestinal cancer, other nongastrointestinal cancer (breast/prostate or lung), or no history of malignancy. Total and out-of-pocket medical expenditures were compared. Among each cohort, risk of high and catastrophic financial burden was determined.

Results: A total of 90,344 individuals were identified, which was extrapolated to a national representative sample of 95,449,062 individuals. Overall, an estimated 365,367 (0.4%) individuals had a gastrointestinal cancer while 2,015,724 (2.1%) had lung, breast, or prostate cancer. Mean adjusted total health expenditures was greater among patients with gastrointestinal cancer ($13,716; 95% confidence interval, $9,805-$17,628) versus patients with nongastrointestinal cancer ($8,665; 95% confidence interval, $8,222-$9,108) or individuals without cancer ($5,807; 95% confidence interval $5,740-$5,874). An estimated 15.8% (n = 57,898) and 7.1% (n = 25,956) of patients with gastrointestinal cancer experienced a high and catastrophic financial burden, respectively. Patients with gastrointestinal cancer had a 64% increased odds of experiencing catastrophic financial burden compared with patients without a history of cancer (odds ratio 1.64, 95% confidence interval, 1.17-2.31). Furthermore, patients with a gastrointestinal cancer had nearly 40% increased odds of high financial burden associated with their care compared with patients without cancer (odds ratio 1.37; 95% confidence interval, 1.00-1.88).

Conclusion: The risk of experiencing catastrophic financial burden among patients with gastrointestinal cancer was considerable, as roughly 1 in 7 patients experienced high financial burden, and 1 in 13 had a catastrophic financial burden.
