IL13 and colorectal carcinoma: The inverse association with lymph node involvement was a result of higher IL13 transcript expression in tumor-adjacent non-cancerous tissue in N1 than N0 CRC patients (3 vs. 0.2, p = 0.028) and a tendency toward its lower expression in tumors from N1 patients (2.2 vs. 9.2, p = 0.158).
