ABSTRACT
BACKGROUND:
Colorectal cancer incidence is rising in adults < 50 years old, possibly due to obesity. Having bariatric surgery (BRS) should hypothetically reduce this trend, but data are limited. This study compared trends of colorectal cancer (CRC) versus other obesity-related gastrointestinal cancers (OGCs) between morbidly obese and post-BRS subjects. MATERIAL ANDMETHODS:
This retrospective cohort study investigated OGC resection trends using the 2006-2013 National Inpatient Sample. Patients with prior BRS and non-BRS controls with body mass index ≥ 40 kg/m2 were included (n = 30,279 total). We divided OGCs into CRC and non-CRC OGCs (esophageal, stomach, liver, gallbladder, and pancreas). We calculated OGC resection trends in patients < 50 and ≥ 50 years old using the average annual percent change (AAPC).RESULTS:
BRS patients with OGCs were younger (59.3 vs 62.3 years old), with more female gender (77.4% vs 57.1%) and White race (72.6% vs 67%) compared with controls (p < 0.05). The number of CRC resections increased across all ages in 2006-2013, especially rectal cancer for BRS patients (AAPC + 19.8%, p = 0.04). The steepest rise in early-onset CRC resections was after BRS versus a lesser increase in morbid obesity controls (AAPC + 18.7% and + 13.7%, respectively, p < 0.001). In contrast, non-CRC OGCs increased in our controls but not post-BRS. In a sensitivity analysis, estimated CRC incidence trends also increased post-BRS despite adjusting for increasing BRS prevalence.CONCLUSION:
Our findings suggest that bariatric surgery is associated with a persistent increase in early-onset CRC trends. Studies are warranted to validate our results and test the impact of bariatric surgery on early-onset CRC biological mechanisms.Palavras-chave
