To investigate the distribution of histopathological types of endocervical adenocarcinoma (EA) as classified by WHO 2020, to evaluate the expression of p16 in EAs and the association between p16 expression and clinicopathological factors. Methods: Cross-sectional descriptive study on 80 cases with final diagnosis of invasive endocervical adenocarcinoma on resection specimens. Results: Of total 80 EAs, 70 (87,5%) were classified as HPV-associated and 10 (18%) as HPV-independent. Among HPVA, most were usual type (50/80, 62,5%) followed by mucinous not otherwise specified (7/80, 8,8%), invasive stratified mucin-producing carcinoma (ISMC, 7/80, 10%), intestinal type and signet-ring cell type (two each, 2/80, 2,5%). Most NHPVAs were of gastric type (10/80, 12,5%) followed by clear cell (2/80, 2,5%). Most common pattern of invasion is Silva C (56,2%), followed by Silva B (35%) and Silva A (8,8%). 46% of cases had lymphovascular invasion and 18,8% had lymph nodes metastases. Among 70 HPVAs, 67 cases (95,7%) showed overexpression of p16, likewise, only 20% (8/10) of HPVI cases are p16 positive. P16 negative were significantly associated with advanced stage (FIGO II-IV, p=0,033), greater size (p=0,04) and presence of lymphovascular invasion (p=0,043)
