This multicenter study aimed to investigate the disparity in clinical features and prognosis among different histopathologic subtypes of endocervical adenocarcinoma (EA) based on the 2014 World Health Organization (WHO) classification.We retrieved and analyzed data from the Chinese Four C Database between 2004 and 2018. 672EA patients with radical hysterectomies from 32 institutions were retrospectively reviewed. Clinicopathologic characteristics, five-year overall survival (OS), and disease-free survival (DFS) were compared based on histological subtypes.The 5-year DFS and OS rates for usual, endometrioid, mucinous, gastric, villoglandular, clear cell/serous/mesonephric EAs were as follows: 81.3 %, 89.1 %, 63.0 %, 35.6 %, 88.6 %, 79.9 %, respectively (P < 0.0001); 87.4 %, 96.6 %, 74.7 %, 34.0 %, 96.7 %, 86.3 %, respectively (P < 0.0001). Gastric- and mucinous-type exhibited a higher frequency of lymph node metastasis, deep stromal invasion, uterine corpus invasion, and recurrence than the usual -type (recurrence rate:50.00 % vs 29.90 % vs 15.50 %, P < 0.0001). Multivariate analysis revealed gastric-type was significantly associated with inferior DFS (HR,3.018; 95 % CI, 1.688-5.397; P < 0.0001) and OS(HR, 4.114; 95 % CI, 2.002-8.453; P < 0.0001). Furthermore, compared to the usual -type, mucinous-type demonstrated significantly worse DFS (HR, 1.773; 95 % CI,1.123-2.8; P = 0.014) and OS (HR, 2.168; 95 % CI,1.214-3.873; P = 0.009) whereas endometrioid-type was an identified as independent factor for better DFS (HR, 0.365; 95 % CI,0.143-0.928; P = 0.034). Villoglandular subtype displayed similar features and favorable prognosis as the usual type.Relevant clinical features and prognosis varied significantly among histological subtypes of EA, thus offering valuable guidance for the development of subtype-specific treatment strategies to optimize EA management.© 2024 Published by Elsevier Ltd.
