CDKN2A and tubular adenoma: In tubular adenomas, but not in HPPs, pro-apoptotic BAX was strongly correlated with anti-apoptotic BCL2 (r = 0.48, p<0.0001), The survivin LI was highly correlated in both types of lesions with the KI-67 LI and with each of the proliferation-related analytes except for p16 in tubular adenomas.
