We updated the Korean Society of Gynecologic Oncology (KSGO) practice guideline for the management of ovarian cancer as version 5.1. The ovarian cancer guideline team of the KSGO published announced the fifth version (version 5.0) of its clinical practice guidelines for the management of ovarian cancer in December 2023. In version 5.0, the selection of the key questions and the systematic reviews were based on the data available up to December 2022.Therefore, we updated the guidelines version 5.0 with newly accumulated clinical data and added 5 new key questions reflecting the latest insights in the field of ovarian cancer between 2023 and 2024. For each question, recommendation was provided together with corresponding level of evidence and grade of recommendation, all established through expert consensus.

Background: Sunitinib, commonly used for metastatic renal cell carcinoma (mRCC), often induces hypothyroidism, affecting 27 to85% of patients. There are clues suggesting an association between sunitinib-induced hypothyroidism and improved survival outcomes. This study aims to identify the predictive factors of sunitinib-induced hypothyroidism and evaluate whether the occurrence of overt or subclinical hypothyroidism predicts tumor outcome in patients with mRCC. Methods: Patients administered to sunitinib for mRCC was included in this retrospective study. Log-rank test and Cox proportional hazards model were conducted to identify predictive factors of hypothyroidism and prognostic factors of progression-free survival (PFS) and overall survival (OS). Results: A total of 156 patients with mRCC treated with sunitinib were included. Predictive factors of sunitinib-induced hypothyroidism werefemale (odds ratio (OR), 2.77), sunitinib-induced hypertension (OR, 2.99) and dose reduction of sunitinib due to intolerance (OR, 3.57). Sunitinib-induced overt hypothyroidism was a significant prognostic factor in predicting PFS and OS (hazard ratio, 0.38 and 0.23, respectively). Thyroid hormone replacement did not have an influence on PFS and OS. Conclusions Female patients, patients who experienced sunitinib-induced hypertension and sunitinib dose reduction are at higher risk of hypothyroidism and need close monitoring. Overt hypothyroidism is a strong prognostic factor of sunitinib treatment outcome in mRCC patients and thyroid hor-mone replacement does not have a negative effect on tumor outcome.

Since the latest practice guidelines for ovarian cancer were developed by the Korean Society of Gynecologic Oncology (KSGO) in 2021, many studies have examined the efficacy and safety of various treatments for epithelial ovarian cancer (EOC). Therefore, the need to develop recommendations for EOC treatments has been raised. This study searched the literature using 4 key items and the Population, Intervention, Comparison, and Outcome: the efficacy and safety of poly-ADP ribose polymerase inhibitors in newly diagnosed advanced EOC; the efficacy and safety of intraperitoneal plus intravenous chemotherapy in optimally debulked advanced EOC; the efficacy and safety of secondary cytoreductive surgery in platinumsensitive recurrent ovarian cancer; and the efficacy and safety of the addition of bevacizumab to platinum-based chemotherapy in first platinum-sensitive recurrent EOC patients who received prior bevacizumab. The evidence for these recommendations, according to each key question, was evaluated using a systematic review and meta-analysis. The committee of ovarian cancer of the KSGO developed updated guidelines for treatments of EOC.
