Practice guidelines for management of uterine corpus cancer in Korea: a Korean Society of Gynecologic Oncology consensus statement
The Korean Society of Gynecologic Oncology (KSGO) had been making an effort to standardize and enhance the quality of domestic uterine corpus cancer treatment by developing updated clinical practice guidelines in 2021. The KSGO revised the guidelines based on a literature search using 4 key elements: Population, Intervention, Comparison, and Outcome framework. These elements include the evaluation of the efficacy and safety of immune checkpoint inhibitor treatment in recurrent/advanced endometrial cancer patients who have failed platinum-based chemotherapy, as well as the effect of combined treatment with trastuzumab in patients with HER2/neu-positive endometrial cancer. Additionally, the guideline assessed the efficacy and safety of omitting lymph node dissection in low-risk endometrial cancer patients, investigated the effect of sentinel lymph node mapping in early-stage endometrial cancer surgery, addressed the outcome of chemoradiation therapy as a postoperative treatment in patients with advanced (stage III-IVA) endometrial cancer, and explored the impact of initial treatment with immune checkpoint inhibitors on survival in patients with advanced or recurrent endometrial cancer patients.
Clinical practice guidelines for uterine corpus cancer: an update to the Korean Society of Gynecologic Oncology guidelines
The Korean Society of Gynecologic Oncology has updated its clinical practice guidelines for endometrial cancer to incorporate advancements in recent high-quality randomized controlled trials. These guidelines address evolving treatment paradigms, and are tailored to the Korean medical context. Key updates include a strong recommendation for doxorubicin/trabectedin combination therapy in metastatic or recurrent unresectable leiomyosarcoma based on the significant survival benefits demonstrated in a randomized controlled trial. For advanced or recurrent endometrial cancer, immune checkpoint inhibitors combined with chemotherapy have received strong recommendations, owing to their proven efficacy and increased accessibility in Korea. Conditional recommendations were made for combination therapies involving durvalumab and olaparib, reflecting their potential benefits, but acknowledging regulatory and accessibility constraints. These guidelines aim to provide evidence-based, practical strategies to optimize care for patients with endometrial cancer while addressing unmet clinical needs and adapting global advancements to Korea's healthcare environment.
Randomized comparison between sentinel lymph node mapping using indocyanine green plus a fluorescent camera versus lymph node dissection in clinical stage I-II endometrial cancer: a Korean Gynecologic Oncology Group trial (KGOG2029/SELYE)
Sentinel lymph node (SLN) mapping has been suggested as an alternative surgical technique to full lymphadenectomy for early-stage endometrial cancer. However, the survival outcomes of SLN mapping compared with lymphadenectomy have not been established via a prospective study. A multi-center, single-blind, randomized controlled trial has been designed to determine the prognostic value of SLN mapping alone compared with conventional lymphadenectomy for patients with clinical stage I-II endometrial cancer. Eligible participants will be randomly assigned in a 1:1 ratio between the group to undergo SLN mapping using indocyanine green and the conventional lymph node dissection group. A high-risk group will undergo a 2-step SLN mapping procedure. The primary endpoint is the 3-year disease-free survival (DFS). The secondary endpoints are 3-year overall survival (OS), 5-year DFS, 5-year OS after surgery, pattern of recurrence, immediate surgical outcomes, success rate of SLN mapping, postoperative lymph-related complications, postoperative quality of life, and postoperative cost effectiveness. The role of pathologic ultrastaging of SLNs will also be assessed. ClinicalTrials.gov Identifier (NCT number): NCT04845828.
Clinical practice guideline for high-risk human papillomavirus testing in cervical cancer screening: a consensus statement from the Korean Society of Gynecologic Oncology
High-risk human papillomavirus (hrHPV) is a necessary cause of cervical cancer, and hrHPV testing has increasingly been recognized as an effective screening tool that overcomes the limitations of cytology-based screening. However, standardized clinical guidance for the use of hrHPV testing in cervical cancer screening has been limited in Korea, resulting in variability in clinical practice. This consensus-based clinical practice guideline was developed under the auspices of the Korean Society of Gynecologic Oncology through multidisciplinary collaboration involving experts in gynecology, pathology, laboratory medicine, and public health. Relevant domestic and international evidence was systematically reviewed, and input from diverse clinical settings was incorporated through four public hearings. Final recommendations were established through expert consensus. The guideline presents four key recommendations: hrHPV testing may be considered for women aged 25 years or older, with a recommended screening interval of 3 to <5 years; screening assays should differentiate HPV genotypes 16 and 18 and detect other high-risk types, with preference given to clinically validated tests; testing should be performed in appropriately equipped settings with standardized specimen handling and reporting, including documentation of HPV 16/18 status in positive cases; and hrHPV testing should be conducted under rigorous internal and external quality control systems. This guideline aims to support consistent and rational implementation of hrHPV testing in cervical cancer screening in Korea.
Risk factors for and prognosis of carboplatin-related hypersensitivity in patients with epithelial ovarian cancer
We aimed to identify the predictive risk factors for carboplatin-related hypersensitive reactions (HRs) and investigate their impact on survival outcomes in patients with epithelial ovarian cancer (EOC). This retrospective study included 222 patients with EOC who received carboplatin infusion between July 2016 and November 2019. We compared the clinicopathologic characteristics and survival outcomes between carboplatin-related hypersensitivity and non-hypersensitivity groups. Hypersensitivity data were classified using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, categorizing grades from 1 to 5 as mild/moderate/severe/life-threatening/death. Multiple logistic regression analysis was used to analyze risk factors of HRs. The Cox proportional hazard regression model was used to determine the factors of being significantly associated with overall survival. Of the 222 patients, eight exhibited HRs (incidence rate, 3.6%). All HRs were of grade 3 or 4 (life-threatening). In all cases, a desensitization protocol was followed. Advanced stage (III or IV) (P = 0.022), previous history of carboplatin use (P < 0.001), and recurrent ovarian cancer (P = 0.001) were significantly associated with HR to carboplatin. Multivariate logistic analysis showed that a previous history of carboplatin was the only independent risk factor for carboplatin-related hypersensitivity (OR, 20.19; 95% CI 1.22 - 3034.10; P = 0.034). However, HR to carboplatin did not influence the overall survival (P = 0.526). In EOC patients, prior use of carboplatin was an independent risk factor for carboplatin-related HRs; HRs to carboplatin did not influence the overall survival. Clinicians should not underestimate the possibility risk of carboplatin HSRs when re-administrating carboplatin in EOC patients.
