However, IL-7 was significantly higher in patients with adenomas displaying a villous growth pattern (villous adenomas and tubulovillous adenomas) as compared to tubular adenomas: 20.6 pg/ml (95% CI 12.9–32.7) and 9.2 pg/ml (7.2–11.8), p = 0.001. This evidence concerns the gene IL7 and tubular adenoma.
