Zhang X, et al. - For early-staged ovarian cancer patients who had unilateral resection, researchers assessed how postoperative chemotherapy impacts response via propensity score matching. They identified patients aged 50 years or younger with early-staged ovarian cancer from the Surveillance, Epidemiology, and End Results program database during 2000-2018. The necessity of chemotherapy was determined using univariate and multivariate cox proportional hazards models. Findings revealed that both overall and cancer-specific survival were not influenced by chemotherapy and this implied that postoperative chemotherapy is not needed for early-staged young ovarian cancer patients with unilateral resection.
