Abstract

Background: Patients with inflammatory bowel disease have markedly increased risk for developing colitis-associated colorectal adenocarcinoma (CAC). There is no established prognostic biomarker for CAC. Materials and Methods: A retrospective study was performed on a cohort of 57 CACs. Expression of caudal type homeobox transcription factor 2 (CDX2) and YES-associated protein 1 (YAP1) expression was correlated with clinicodemographic and histopathological features. Results: Neither YAP1 nor CDX2 expression alone was significantly associated with tumor invasion beyond the muscularis propria or lymph node status. However, a subgroup of CAC with double negativity for expression of YAP1 and CDX2 was more frequently found in younger patients, and more frequently associated with higher pathological tumor stage and nodal metastasis. Furthermore, a positive correlation between CDX2 and YAP1 expression was identified in CAC and sporadic colorectal adenocarcinoma. Conclusion: Our study demonstrates that double negativity for expression of YAP1 and CDX2 defines a subgroup of CAC with early onset and aggressive clinical features.
