Role of Adjuvant Chemotherapy in Stage I Pure Ovarian Immature Teratoma: A Systematic Review and Meta-Analysis.

ABSTRACT: To determine the role of adjuvant chemotherapy in stage IA G2-3 and stage IB-IC pure ovarian immature teratoma (POIT), we performed a systematic review and meta-analysis by searching PubMed, Embase, Cochrane library, Web of Science, and ClinicalTrials.gov. Randomized controlled trials or cohort studies on stage IA G2-G3 or stage IB-IC POIT between 1 January 1970 and 15 December 2022 were enrolled. The recurrence rate and mortality rate were the primary outcomes, and subgroup analysis based on the tumor stage and grade was also conducted. In total, 15 studies with 707 patients were included. Compared with surveillance, adjuvant chemotherapy significantly decreased the mortality rate (RR 0.31, 95% CI 0.11-0.88, p = 0.03), but not recurrence (RR 0.74, 95% CI 0.39-1.42, p = 0.37)
