Additionally, patients with CeD had higher densities of CD3+ and CD8+ tumor-infiltrating lymphocytes (TILs) than individuals with Crohn’s disease-associated SBC or sporadic SBC, which was associated with a better prognosis (CD3+ TIL: 23.7% vs. 3.3% vs. 5.5%, respectively; CD8+ TIL: 18.6% vs. 1% vs. 4%, respectively). Here, CD8A is linked to Crohn disease.
