RESUMO
OBJECTIVE: To evaluate the prognosis of endocervical adenocarcinomas after reclassification according to the morphologic type based on the 2020 World Health Organization Classification. METHODS: A retrospective longitudinal study with cases admitted at the University of Campinas, Brazil, from 2013 to 2020. The sample included 140 cases morphologically reclassified: 100 cases as adenocarcinoma HPV-associated (HPVA), 17 as HPV-independent (HPVI), and 23 non-HPVA/HPVI. Clinic and pathologic variables were evaluated. Analyses were performed by χ2 , Fisher exact, and Mann-Whitney U tests, Kaplan-Meier curves, Log-rank test, and Cox regression. RESULTS: Compared with the HPVA group, advanced stage (FIGO Stage II+) was more frequent in the HPVI group (P = 0.009), which also showed older patients (P = 0.032), and a higher proportion of deaths (P = 0.006). The median overall survival (OS) differed between groups: 73.3 months in HPVA and 42.4 months in HPVI (P = 0.005). At the multivariate analysis, the risk of death was 6.7 (95% confidence interval 1.9-23.0) times higher in patients diagnosed in advanced stages. CONCLUSION: HPVI cases were more frequent in older patients, presenting at more advanced stages and with worse OS. The morphology-based approach of the new WHO classification appears to be prognostically valuable and applicable in lower- and middle-income settings.
