BACKGROUND: Detection and removal of colonic adenomatous polyps (CAP) decreases colorectal cancer (CRC) development, particularly with more or larger polyps or polyps with advanced villous/dysplastic histology. Immunosuppression following solid organ transplantation (SOT) may accelerate CAP development and progression compared to average-risk population but the benefit of earlier colonoscopic surveillance is unclear.
AIMS: Study the impact of maintenance immunosuppression post-SOT on developmental timing, multiplicity and pathological features of CAP, by measuring incidence of advanced CAP (villous histology, size ≥ 10 mm, ≥ 3 polyps, presence of dysplasia) post-SOT and the incidence of newly diagnosed CRC compared to average-risk age-matched population.
METHODS: Single-center retrospective cohort study of SOT recipients.
RESULTS: 295 SOT recipients were included and were compared with 291 age-matched average-risk controls. The mean interval between screening and surveillance colonoscopies between SOT and control groups was 6.3 years vs 5.9 years (p = 0.13). Post-SOT maintenance immunosuppression mean duration averaged 59.9 months at surveillance colonoscopy. On surveillance examinations, SOT recipients exhibited more advanced (≥ 10 mm) adenomas compared to matched controls (9.2% vs. 3.8%, p = 0.034; adjusted OR 2.38; 95% CI 1.07-5.30).
CONCLUSION: SOT recipients appear at higher risk for developing advanced CAP, suggesting that earlier surveillance should be considered.
