Patients diagnosed with stage I OCCC from 1988 to 2018 were included for further analysis. X-Tile software was used to identify the potential cutoff point for tumor size. Stratification analysis, propensity score matching, and inverse probability weighting analysis were used to balance the potential confounding factors.<h4>Results</h4>A total of 1,000 stage I OCCC patients were included. Of these 1,000 patients, median follow-up was 106 months (95% confidence interval [CI]: 89-112 Frontiers in oncology862944https://www.ebi.ac.uk/biostudies/studies/S-EPMC9149085biostudies-literatureTumor Size Is an Independent Prognostic Factor for Stage I Ovarian Clear Cell Carcinoma: A Large Retrospective Cohort Study of 1,000 Patients.PMC9149085Wu LShi SZhang HSun HfalseTumor Size Is an Independent Prognostic Factor for Stage I Ovarian Clear Cell Carcinoma: A Large Retrospective Cohort Study of 1,000 Patients.<h4>Objective</h4>The aim of this study was to investigate the prognostic value and stratification cutoff point for tumor size in stage I ovarian clear cell carcinoma (OCCC).<h4>Methods</h4>This was a retrospective cohort study using the Surveillance, Epidemiology, and End Results database (version: SEER 8.3.9).
