Introduction:
It is unknown whether underutilization of cancer-directed surgery (CDS) in patients with Medicaid contributes to worse overall survival (OS) across various operative risk spectrum in comparison to non-Medicaid patients.
Method:
The SEER database linked to Medicaid enrollment files between 2006 and 2013 was used. Spectrum of operative risks included pancreatic ductal adenocarcinoma (PDAC)-high-risk, colon cancer (CC)-intermediate-risk, or melanoma-low-risk. Multivariable Cox proportional-hazard and logistic regression analyses were used.
Results:
There were 7,595 Medicaid and 163,416 non-Medicaid patients. Being in Medicaid was associated with higher odds of not undergoing CDS for CC (OR 1.88, 95% CI 1.41-2.52) and PDAC (OR 2.20, 95% CI 1.73-2.80). Correspondingly, not undergoing CDS was associated with worse survival (CC-HR 4.76, 95% CI 3.82-5.93; PDAC-HR 2.40, 95% CI 2.21-2.60) in Medicaid group vs non-Medicaid group. For melanoma, there was a larger impact of not undergoing CDS on OS in Medicaid compared to non-Medicaid population (HR 1.75, 95% CI 1.07-2.89).
Conclusion:
Across cancers with different operative risks, increasing the use of CDS may help reduce the OS gaps between Medicaid and non-Medicaid population.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
