Inverse association between statin use and head and neck cancer: A population‐based case‐control study in Han population

Abstract

Background

This case‐control study aimed to find the relationship between prior statin use and head and neck cancer occurrence using a large population‐based database.

Methods

This study used claims data from the Taiwan Longitudinal Health Insurance Database. We included 5515 patients with head and neck cancer as cases and 5515 propensity score‐matched patients without head and neck cancer as controls. Conditional logistic regressions were performed to investigate the relationship between head and neck cancer and prior statin exposure.

Results

Of the 11 030 total sampled patients, 16.95% had previously received prescriptions for statins. In addition, statin exposure was found in 15.99% of cases and 17.91% of controls. The logistic regression also revealed that the adjusted odds ratio of prior statin exposure for cases was 0.86 (95% confidence interval: 0.77‐0.95) compared to propensity score‐matched controls.

Conclusion

This study found an inverse association between statin usage and head and neck cancer occurrence.
