- Abstract
Introduction: Obesity has a known association with certain types of malignancy, and we aimed to determine whether bariatric surgery has a protective effect against de novo obesity-associated cancer development in adult patients. Methods: We performed a multi-center retrospective cohort studying utilizing TriNetX national database. Patients were identified utilizing ICD-10-CM coding, and propensity score matching was performed. We compared patients with obesity who underwent bariatric surgery to patients with obesity who did not undergo bariatric surgery. Results: We initially identified 60,285 patients in the bariatric surgery group and 1,570,440 patients in nonsurgical control group. After propensity score matching, we included 55,789 patients in each patient cohort. The cumulative incidence of de novo obesity-associated cancers at 10 years was 4.0% (2206 patients) in the bariatric surgery group and 8.9% (4,960 patients) in the nonsurgical control group (HR 0.482 [95% CI 0.459–0.507]). The bariatric surgery group had lower incidence proportions for de novo breast cancer (HR 0.753 [CI 0.678–0.836]), colon cancer (HR 0.638 [CI 0.541–0.752]), liver cancer (HR 0.370 [CI 0.345–0.396]), ovarian cancer (HR 0.654 [CI 0.531–0.806]), and endometrial cancer (HR 0.448 [CI 0.362–0.556]) when compared to the nonsurgical control group. Conclusion: We noted that bariatric surgery is associated with a significantly lower cumulative incidence of de novo obesity-associated cancer compared to a nonsurgical matched control group. Incidence proportions of de novo breast, colon, liver, ovarian, and endometrial cancer were significantly lower in adult patients with obesity in the bariatric surgery group compared to the nonsurgical group.
