CDKN2A and adenocarcinoma: Correlating p16INK4a expression with clinico-pathological parameters, we found that p16INK4a expression was directly proportional to the diagnosis of cervical tumors where 90.1% of SCC cases and 76.9% as Adenocarcinoma (AC) showed positive p16INK4a expression, which is in agreement with previous studies [15, 29, 30].
