INTRODUCTION: There are studies with mixed conclusions about the role cholecystectomy plays as a risk factor for proximal colorectal cancer (CRC).
METHODS: We performed a multicenter retrospective cohort study where the records of patients with CRC were reviewed. Data was collected regarding affected colon subsegment (cecum, ascending, transverse, descending, sigmoid, or rectum, which were also combined into proximal or distal colon), history and time since cholecystectomy, histopathology reports (TNM classification and clinical stage), and KRAS, NRAS, and BRAF mutation analysis. Univariate and multivariate analysis adjusting for age, smoking history, body mass index, sex, and family history of cancer were performed. Logistical regression for statistical analysis was used to estimate the odds ratio for the association between cholecystectomy and tumor location.
RESULTS: Four hundred four cases were obtained, of which 52 previously had cholecystectomy. The date of surgery was recorded in 43 patients, with a 5 y median and an interquartile range of 1.5-14 y prior to CRC diagnosis. Both crude and adjusted odds ratio (2.86 and 2.42, respectively) confirmed an associated risk for developing proximal CRC after cholecystectomy. When proximal CRC cases with previous cholecystectomy were directly compared against proximal CRC without cholecystectomy and distal CRC cases, the former had a higher distribution of prevalence for T3, T4b, N1b, M1a, and M1c. KRAS mutation also presented its highest prevalence in this group with 33%.
CONCLUSIONS: Cholecystectomy was related to the development of proximal CRC in all its subsegments, seemingly associated with higher stages at diagnosis. Close surveillance should be considered in patients who undergo cholecystectomy.
