Abstract
Background
Obesity increases the risk of multiple cancers.
Objective
The purpose of this manuscript is to review the high-quality studies that have provided
the most compelling evidence around the association between bariatric surgery and
cancer risk.
Setting
Literature review.
Methods
The literature was reviewed for large high quality observational studies with well
matched controls. Identified studies were summarized in this review.
Results
Four large cohort studies were identified and summarized including the Swedish Obese
Subjects study, the Utah cohorts, the Kaiser Permanente studies and the SPLENDID study.
All four cohorts demonstrated a strong association between bariatric surgery and a
reduction in cancer risk. Two of the cohorts showed a reduction in cancer related
mortality, and two of the cohorts found a dose-response between amount of weight loss
following bariatric surgery and cancer risk.
Conclusions
The evidence that bariatric surgery is associated with a reduced risk of cancer is
compelling.
