RESUMO
The Korean Gynecologic Oncology Group (KGOG) was established in 2002 and is the only organization in Korea conducting multi-center clinical trials for gynecologic cancers. Since its re-establishment as a non-profit organization in 2021, KGOG has grown significantly, now including 207 gynecologic oncology specialists from 76 hospitals. This growth is a testament to the dedication and hard work of all those involved in the organization. KGOG is committed to maximizing the activation of multi-center clinical research through policies that support patients with rare diseases and gynecologic cancer research, focusing on strengthening institutional capacity, equalizing participation opportunities, and enhancing information sharing. A significant milestone for KGOG was becoming a member of the US Gynecologic Oncology Group (GOG) in 2005, allowing participation in GOG clinical trials. KGOG later joined the Gynecologic Cancer InterGroup (GCIG) and strengthened its capabilities by hosting the first Endometrial Cancer Consensus Conference-Clinical Research (ECCC-CR) in 2023. KGOG holds biannual meetings and symposia, as well as 224 operating committee meetings annually to review the discussions of the Tumor Site Committee. KGOG has conducted 156 investigator-initiated trial (IIT) or sponsor-initiated trial (SIT) studies as KGOG-led or participated in research. Currently, 18 studies are registered, and 10 are in preparation. To date, 68 papers have been published. KGOG conducts six national projects and collaborates with external organizations such as the NRG Oncology Foundation, Gynecologic Oncology Group Partners (GOG-P), GCIG, East Asian Gynecologic Oncology Trial group (EAGOT), and the Japanese Gynecologic Oncology Group (JGOG). Through collaboration with renowned international research institutions, KGOG has significantly expanded the scope of its research, achieving noteworthy clinical outcomes. This report not only introduces the history and recent status of KGOG but also presents the exciting future direction of the organization, filled with potential breakthroughs and advancements in gynecologic oncology research.
RESUMO
BACKGROUND: Although two recent phase III randomized controlled trials showed survival benefits of undergoing secondary cytoreductive surgery for an initial relapse of ovarian cancer, patients who received a poly-ADP ribose polymerase inhibitor (PARPi) as the first-line maintenance treatment, which is currently the standard treatment for advanced ovarian cancer, were not included in those trials. Therefore, determining an optimal treatment strategy, including secondary cytoreductive surgery, in patients whose cancer progresses even with PARPi treatment, is needed. PRIMARY OBJECTIVE: To determine whether secondary cytoreductive surgery is beneficial in patients who have progressed on PARPi maintenance treatment. STUDY HYPOTHESIS: Secondary cytoreductive surgery followed by chemotherapy is superior to chemotherapy alone for patients who have progressed on PARPi maintenance treatment. TRIAL DESIGN: The SOCCER-P study is a multicenter randomized phase II clinical trial. Patients who meet the eligibility criteria will be randomized to either undergo secondary cytoreductive surgery and subsequent platinum-based chemotherapy plus or minus bevacizumab, or to receive platinum-based chemotherapy plus or minus bevacizumab alone. Patients randomly allocated to the surgery group will undergo secondary cytoreductive surgery followed by six cycles of a physician's choice of platinum-based chemotherapy once they have recovered from surgery. MAJOR INCLUSION/EXCLUSION CRITERIA: The major inclusion criteria are as follows: first recurrence of disease with treatment-free interval from last platinum dose (TFIp) ≥6 months and progression during PARPi maintenance or treatment-free interval from last PARPi therapy (TFIPARPi) <3 months. The major exclusion criteria are as follows: >1 line of prior chemotherapy, TFIp <6 months, and radiological signs suggesting metastases not accessible to surgical removal (complete resection is deemed not possible). PRIMARY ENDPOINT: Progression-free survival. SAMPLE SIZE: 124 patients. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Accrual completion approximately the end of 2026 and the results are expected after 2 years of follow-up in 2029. TRIAL REGISTRATION: NCT05704621.

Detecting ovarian cancer (OC) early using existing biomarkers, e.g., cancer antigen 125 (CA125), is challenging due to its ubiquitous expression in many tissues. Doppel, a prion-like protein, expresses in male reproductive organ but absent in female reproductive systems and healthy tissues, but plays an important role in neoangiogenesis. Here, we have shown two platforms, soluble Doppel in sera/ascites and Doppel expressed circulating tumor cells ( Dpl+ CTC) in the whole blood, to detect subsets of epithelial OC (EOC). Increased level of Doppel in the sera of OC patients, in three different cohorts, confirm Doppel as OC specific biomarker. Serum Doppel level distinguishes EOC subtypes and early stages HGSOCs from non-cancerous conditions with high sensitivity and specificity. Stratifying the EOCs based on Doppel level, we categorized them into Doppel-high (Dpl hi ) and Doppel-low (Dpl low ) groups. Using ascites-derived organoids and single cell sequencing of whole ascites of Dpl hi and Dpl low patients, we identify that Doppel induces epithelial-mesenchymal transition (EMT) and creates an immunosuppressive microenvironment, respectively. Doppel levels in the sera/ascites correlate with the changes of Dpl+ CTC number in whole blood, highlighting the association of Doppel-induced EMT with CTC dissemination in circulation. Thus, Doppel-based detection of EOC subtypes could be a promising platform as clinical biomarker and link Doppel-axis with OC dissemination.
RESUMO
Ovarian cystectomy, aimed at preserving fertility, has advanced through minimally invasive surgical techniques. This study evaluates the learning curves and surgical outcomes of three such approaches: DaVinci Robotic Single-Site (RSS), DaVinci Robotic Single-Port (RSP), and laparo-endoscopic single-site surgery (LESS). To analyze the learning curves and surgical outcomes for these techniques, providing insights into their effectiveness and proficiency development. Retrospective analysis of 104 patients with ovarian tumors, divided into RSS (n = 52), RSP (n = 22), and LESS (n = 30) groups. Metrics analyzed included age, BMI, tumor size, hemoglobin drop, operative time, docking time, console time, and tumor location. No significant differences in age, BMI, transfusion rate, hemoglobin drop, or length of stay were found among the groups. RSS had larger tumors on average, and LESS had a higher occurrence rate on the right side. LESS demonstrated the shortest operative time, while RSS and RSP had comparable times. Docking and console times did not differ significantly between RSS and RSP. RSP reached proficiency faster than RSS in docking and console times, while LESS exhibited the greatest variability in operative time. RSP offers a faster and more consistent learning curve, making it advantageous for complex procedures, whereas LESS provides shorter operative times but with higher variability. These findings are crucial for surgical training and resource allocation in medical institutions.
RESUMO
BACKGROUND: This study aimed to evaluate the association between the dietary intake of vitamin B complex (thiamine, riboflavin, and niacin) and cervical cancer in Korea. METHODS: The data from the Korean National Health and Nutrition Examination Survey (KNHANES) from 2010 to 2021 were analyzed, which included 28,306 participants who were categorized into non-cervical cancer and cervical cancer groups. The following dietary intake threshold levels of thiamine, riboflavin, and niacin were identified based on the recommended daily allowances (RDAs): thiamine, 1.1 mg/day; riboflavin, 1.2 mg/day; and niacin, 14 mg/day. RESULTS: Among 28,306 participants, 27,976 were in the non-cervical cancer group and 330 were in the cervical cancer group. Riboflavin intakes of more than 1.2 mg/day but less than 2.4 mg/day were associated with a significantly reduced risk of cervical cancer, whereas intakes of above 2.4 mg/day were not associated with cervical cancer. Thiamine and niacin intakes were not significantly related to the risk of cervical cancer. CONCLUSIONS: The results of this study suggest that an intake of riboflavin of 1.2-2.4 mg/day may contribute to a lower risk of cervical cancer.
RESUMO
This fifth revised version of the Korean Society of Gynecologic Oncology practice guidelines for the management of cervical cancer incorporates recent research findings and changes in treatment strategies based on version 4.0 released in 2020. Each key question was developed by focusing on recent notable insights and crucial contemporary issues in the field of cervical cancer. These questions were evaluated for their significance and impact on the current treatment and were finalized through voting by the development committee. The selected key questions were as follows: the efficacy and safety of immune checkpoint inhibitors as first- or second-line treatment for recurrent or metastatic cervical cancer; the oncologic safety of minimally invasive radical hysterectomy in early stage cervical cancer; the efficacy and safety of adjuvant systemic treatment after concurrent chemoradiotherapy in locally advanced cervical cancer; and the oncologic safety of sentinel lymph node mapping compared to pelvic lymph node dissection. The recommendations, directions, and strengths of this guideline were based on systematic reviews and meta-analyses, and were finally confirmed through public hearings and external reviews. In this study, we describe the revised practice guidelines for the management of cervical cancer.

BACKGROUND: Bulky or multiple lymph node (LN) metastases are associated with poor prognosis in cervical cancer, and the size or number of LN metastases is not yet reflected in the staging system and therapeutic strategy. Although the therapeutic effects of surgical resection of bulky LNs before standard treatment have been reported in several retrospective studies, well-planned randomized clinical studies are lacking. Therefore, the aim of the Korean Gynecologic Oncology Group (KGOG) 1047/DEBULK trial is to investigate whether the debulking surgery of bulky or multiple LNs prior to concurrent chemoradiation therapy (CCRT) improves the survival rate of patients with cervical cancer IIICr diagnosed by imaging tests. METHODS: The KGOG 1047/DEBULK trial is a phase III, multicenter, randomized clinical trial involving patients with bulky or multiple LN metastases in cervical cancer IIICr. This study will include patients with a short-axis diameter of a pelvic or para-aortic LN ≥2 cm or ≥3 LNs with a short-axis diameter ≥1 cm and for whom CCRT is planned. The treatment arms will be randomly allocated in a 1:1 ratio to either receive CCRT (control arm) or undergo surgical debulking of bulky or multiple LNs before CCRT (experimental arm). CCRT consists of extended-field external beam radiotherapy/pelvic radiotherapy, brachytherapy and LN boost, and weekly chemotherapy with cisplatin (40 mg/m²), 4-6 times administered intravenously. The primary endpoint will be 3-year progression-free survival rate. The secondary endpoints will be 3-year overall survival rate, treatment-related complications, and accuracy of radiological diagnosis of bulky or multiple LNs. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05421650; Clinical Research Information Service Identifier: KCT0007137.

BACKGROUND: The aim of this study was to evaluate the relationship between depressed mood and gynecological cancer outcomes, identifying risk factors for cancer aggravation. METHODS: This study was a retrospective analysis of gynecological cancer patients (January 2020-August 2022) at Korea University Anam Hospital using Patient Health Questionnaire-9 (PHQ-9). Patients were classified into non-depressed mood (NDM)- and depressed mood (DM)-based scores. Statistical analysis was performed using Student's t-test, chi-square test, Fisher's exact test, Kaplan-Meier analysis, and Cox regression analyzing using SPSS. RESULTS: Of the 217 participants, the NDM group comprised 129 patients, and the DM group comprised 88. The two-year disease-free survival (DFS) rates showed significant differences (NDM, 93.6%; DM 86.4%; p = 0.006), but overall survival (OS) did not (p = 0.128). Patients with stage 3 or higher cancer, undergoing five or more chemotherapies, experiencing post-chemotherapy side effects, and depressed mood had an increased risk of cancer aggravation. CONCLUSIONS: Appropriate treatment of depressed mood, as well as adequate treatment for advanced gynecological cancer patients, those with numerous CTx., and those with post-CTx. side effects, may contribute to reducing the risk of cancer aggravation.

Importance: Hyperthermic intraperitoneal chemotherapy (HIPEC) followed by interval cytoreductive surgery (ICS) has shown survival benefits for patients with advanced-stage ovarian cancer. However, there is still a lack of consensus regarding the integration of HIPEC into clinical practice. Objective: To evaluate the safety and effectiveness of ICS with HIPEC compared with ICS alone in clinical practice for patients with advanced-stage ovarian cancer. Design, Setting, and Participants: This prospective, multicenter, comparative effectiveness cohort study enrolled 205 patients with stage III or IV ovarian cancer who had received at least 3 cycles of neoadjuvant chemotherapy followed by ICS with HIPEC or ICS without HIPEC at 7 Korean Gynecologic Oncology Group institutions between September 1, 2017, and April 22, 2022. Nine patients were excluded because they did not meet the inclusion criteria. Exposures: Neoadjuvant chemotherapy followed by ICS with HIPEC or ICS without HIPEC. Main Outcomes and Measures: The primary end point was progression-free survival (PFS). Overall survival (OS) and the safety profile were the key secondary end points. Results: This study included 196 patients (median age, 58.0 years [range, 38-82 years]), of whom 109 underwent ICS with HIPEC and 87 underwent ICS without HIPEC. The median duration of follow-up was 28.2 months (range, 3.5-58.6 months). Disease recurrence occurred in 128 patients (65.3%), and 30 patients (15.3%) died. Interval cytoreductive surgery with HIPEC was associated with a significant improvement in median PFS compared with ICS without HIPEC (22.9 months [95% CI, 3.5-58.6 months] vs 14.2 months [95% CI, 4.0-56.2 months]; P = .005) and median OS (not reached [95% CI, 3.5 months to not reached] vs 53.0 [95% CI, 4.6-56.2 months]; P = .002). The frequency of grade 3 or 4 postoperative complications was similar in both groups (ICS with HIPEC, 3 of 109 [2.8%] vs ICS without HIPEC, 3 of 87 [3.4%]; P > .99). Among patients with recurrence, the frequency of peritoneal recurrence was lower in the ICS with HIPEC group than in the ICS without HIPEC group (21 of 64 [32.8%] vs 41 of 64 [64.1%]; P = .001). Conclusions and Relevance: This study suggests that ICS in conjunction with HIPEC was associated with longer PFS and OS than ICS without HIPEC for patients with advanced-stage ovarian cancer and was not associated with higher rates of postoperative complications. The lower rate of peritoneal recurrence after HIPEC may be associated with improved OS.

This study was conducted to evaluate the efficacy and safety of Unicenta in female subjects with menopausal symptoms by analyzing the changes in the Kupperman index (primary endpoint) and hormonal changes (secondary endpoint). It was a randomized, multi-center, double-blind, parallel, non-inferiority clinical study conducted at two different tertiary medical centers. A Unicenta injection was shown to be non-inferior to Melsmon based on the Kupperman index in both the intent-to-treat and per-protocol populations (p = 0.789 and p = 0.826, respectively). Additionally, there were no statistically significant differences in hormone levels (estradiol, follicular-stimulating hormone) or in the evaluation of facial flushes. There was no statistically significant difference in the incidence rate of adverse events between the two groups (p = 0.505). The study demonstrated that Unicenta is not inferior to Melsmon in terms of the change in the Kupperman index after 12 days of injection. The efficacy and safety of Unicenta were shown, resulting in the improvement of menopausal symptoms.

Colposcopy is the gold standard diagnostic tool for identifying cervical lesions. However, the accuracy of colposcopies depends on the proficiency of the colposcopist. Machine learning algorithms using an artificial intelligence (AI) system can quickly process large amounts of data and have been successfully applied in several clinical situations. This study evaluated the feasibility of an AI system as an assistive tool for diagnosing high-grade cervical intraepithelial neoplasia lesions compared to the human interpretation of cervical images. This two-centered, crossover, double-blind, randomized controlled trial included 886 randomly selected images. Four colposcopists (two proficient and two inexperienced) independently evaluated cervical images, once with and the other time without the aid of the Cerviray AI® system (AIDOT, Seoul, Republic of Korea). The AI aid demonstrated improved areas under the curve on the localization receiver-operating characteristic curve compared with the colposcopy impressions of colposcopists (difference 0.12, 95% confidence interval, 0.10-0.14, p < 0.001). Sensitivity and specificity also improved when using the AI system (89.18% vs. 71.33%; p < 0.001, 96.68% vs. 92.16%; p < 0.001, respectively). Additionally, the classification accuracy rate improved with the aid of AI (86.40% vs. 75.45%; p < 0.001). Overall, the AI system could be used as an assistive diagnostic tool for both proficient and inexperienced colposcopists in cervical cancer screenings to estimate the impression and location of pathologic lesions. Further utilization of this system could help inexperienced colposcopists confirm where to perform a biopsy to diagnose high-grade lesions.
RESUMO
OBJECTIVE: To investigate the impact of conization on survival outcomes and to identify a specific population that might benefit from conization before radical hysterectomy (RH) in patients with early-stage cervical cancer. METHODS: From six institutions in Korea, we identified node-negative, margin-negative, parametria-negative, 2009 FIGO stage IB1 cervical cancer patients who underwent primary type C RH between 2006 and 2021. The patients were divided into multiple groups based on tumor size, surgical approach, and histology. We performed a series of independent 1:1 propensity score matching and compared the survival outcomes between the conization and non-conization groups. RESULTS: In total, 1254 patients were included: conization (n = 355) and non-conization (n = 899). Among the matched patients with a tumor size of >2 cm, the conization group showed a significantly better 3-year disease-free survival (DFS) rate compared with the non-conization group when RH was conducted via minimally invasive surgery (MIS), in those with squamous cell carcinoma (96.3% vs. 87.4%, P = 0.007) and non-squamous cell carcinoma (97.0% vs. 74.8%, P = 0.021). However, no difference in DFS was observed between the two groups among the matched patients with a tumor size of ≤2 cm, regardless of surgical approach or histological type. In patients who underwent MIS RH, DFS significantly worsened as the residual tumor size increased (P < 0.001). CONCLUSION: Cervical conization was associated with a lower recurrence rate in patients with early-stage cervical cancer with a tumor size of >2 cm who underwent primary MIS RH. Cervical conization may be performed prior to MIS RH to minimize the uterine residual tumor.

Non-puerperal uterine inversion is an extremely rare and potentially dangerous condition. Cases are poorly described in the literature, and their actual incidence is unknown. A 34-year-old nulliparous female patient visited the emergency department following a loss of consciousness. She had experienced continuous vaginal bleeding over the preceding two months, with a two-day history of worsening symptoms. The patient showed signs of hypovolemic shock secondary to unceasing vaginal bleeding. Ultrasound and computed tomography revealed an inverted uterus and a large hematoma inside the patient's vaginal cavity. An emergency explorative laparoscopy was performed, which confirmed uterine inversion. Initially, Johnson's maneuver was attempted under laparoscopic visualization, but this failed to achieve uterine reduction. Following the unsuccessful performance of Huntington's maneuver, a re-trial of the manual reduction allowed the uterus to recover to its normal anatomy. The patient's vaginal bleeding was dramatically reduced after successful uterine reduction. The pathologic report conducted confirmed endometrioid adenocarcinoma. Laparoscopic visualization is a feasible and safe procedure for achieving uterine reduction in cases of non-puerperal uterine inversion with an unconfirmed pathology. Uterine malignancies should be considered in patients with non-puerperal uterine inversion.

BACKGROUND: The aim of this study is to compare the surgical outcomes of single-port laparoscopic surgery (SPLS) and single-port robotic surgery (SPRS). METHODS: We retrospectively analyzed patients who underwent a hysterectomy, ovarian cystectomy, or myomectomy with SPLS or SPRS from January 2020 to July 2022. Statistical analyses were performed using the SPSS chi-square test and student's t-test. RESULTS: A total of 566 surgeries including single-port laparoscopic hysterectomy (SPLH; n = 148), single-port robotic hysterectomy (SPRH; n = 35), single-port laparoscopic ovarian cystectomy (SPLC; n = 207), single-port robotic ovarian cystectomy (SPRC; n = 108), single-port laparoscopic myomectomy (SPLM; n = 12), and single-port robotic myomectomy (SPRM; n = 56). The SPRH, SPRC, and SPRM groups had a shorter operation time than the SPLS group, although the results were not statistically significant (SPRH vs. SPLH, p = 0.134; SPRC vs. SPLC, p = 0.098; SPRM vs. SPLM, p = 0.202). Incisional hernia occurred as a postoperative complication in two patients only in the SPLH group. Postoperative Hb changes were lower in the SPRC and SPRM groups than in the SPLC and SPLM groups (SPRC vs. SPLC, p = 0.023; SPRM vs. SPLM, p = 0.010). CONCLUSIONS: Our study demonstrated that the SPRS had comparable surgical outcomes when compared to the SPLS. Therefore, the SPRS should be considered a feasible and safe option for gynecologic patients.
RESUMO
Carcinosarcomas (malignant mixed Mullerian tumors) of a female genital organ are rare tumors associated with a poor survival. The purpose of this study was to identify site-specific differences in the incidence and prognosis in carcinosarcomas originating in the uterus, cervix, or ovary. The data of patients with gynecologic carcinosarcomas were extracted from the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2016. The characteristics of gynecologic carcinosarcomas were compared using Pearson X2 and Fisher's exact tests. Kaplan-Meier models were used for cause-specific survival (CSS) analysis. The cohort included 7086 females, including 5731 cases of uterine carcinosarcoma, 161 cervical carcinosarcomas, and 1193 ovarian carcinosarcomas. The age-adjusted incidence rates of uterine, cervical, and ovarian carcinosarcoma were 3.9, 0.1, and 0.6 per 1,000,000, respectively. In the distribution of carcinosarcoma incidence by race, compared with the uterus or cervix, those originating from the ovary were unequally distributed in Caucasians (84.4% versus 69.6%, 67.7%; p < 0.001). The incidence of uterine carcinosarcoma steadily increased over time, from 2.2 in 2000 to 5.5 in 2016 (per 1,000,000), while cervical or ovarian carcinosarcoma showed no significant difference in incidence. The five-year CSS rates based on the site of origin (uterus, cervix, and ovary) were 39.9%, 33.1%, and 25.8%, respectively. The incidence rates of gynecologic carcinosarcoma, especially uterine carcinosarcoma, are gradually increasing. Although uterine carcinosarcoma is associated with a higher incidence than the others, it has a better prognosis compared with ovarian and cervical carcinosarcoma. The survival rates were worst in ovarian carcinosarcoma.
RESUMO
Standard treatments for gynecological cancers include surgery, chemotherapy, and radiation therapy. However, there are limitations associated with the chemotherapeutic drugs used to treat advanced and recurrent gynecological cancers, and it is difficult to identify additional treatments. Therefore, immune checkpoint inhibitor (ICI) therapy products, including PD-1/PD-L1 inhibitors and CTLA-4 inhibitors, are in the spotlight as alternatives for the treatment of advanced gynecological cancers. Although the ICI monotherapy response rate in gynecological cancers is lower than that in melanoma or non-small cell lung cancer, the response rates are approximately 13-52%, 7-22%, and 4-17% for endometrial, ovarian, and cervical cancers, respectively. Several studies are being conducted to compare the outcomes of combining ICI therapy with chemotherapy, radiation therapy, and antiangiogenesis agents. Therefore, it is critical to determine the mechanism underlying ICI therapy-mediated anti-tumor activity and its application in gynecological cancers. Additionally, understanding the possible immune-related adverse events induced post-immunotherapy, as well as the appropriate management of diagnosis and treatment, are necessary to create a quality environment for immunotherapy in patients with gynecological cancers. Therefore, in this review, we summarize the ICI mechanisms, ICIs applied to gynecological cancers, and appropriate diagnosis and treatment of immune-related side effects to help gynecologists treat gynecological cancers using immunotherapy.

BACKGROUND: Although the incidence of cervical cancer has decreased since the 1980s in Korea, it remains high among the elderly women. This study evaluated the suitability of cervical cancer screening for elderly Korean women aged ≥65 years according to recommendations by the American Society of Cytopathology and American Society for Colposcopy and Cervical Pathology. METHODS: We retrospectively reviewed the records of patients who underwent cervical cancer screening, followed by liquid-based Pap test, human papillomavirus (HPV) test, and colposcopic punch biopsy at two academic hospitals from May 2008 to May 2018. The participants were divided into two groups <65 and ≥65 years old. Logistic regression analysis was performed to evaluate the association between cytology tests, HPV tests and the occurrence of high-risk lesions, ≥cervical intraepithelial neoplasia2 (CIN2). RESULTS: The mean patient age was 49.02 ± 15.437 (range 15-91) years. No patients aged <25 years showed atypical squamous cell-cannot exclude high grade (ASC-H), squamous cell carcinoma (SCC), or adenocarcinoma (ADC). The incidence of high-grade squamous intraepithelial lesion (HISL) (39.7%) and ≥CIN 3 (40.2%) was significantly higher in patients ≥65 years of age than in other age groups. However, patients ≥65 years showed increased HSIL and HPV negativity and ASC-H, HSIL, and HPV positivity in those with ≥CIN 2 (both p = .043). CONCLUSION: Korean women aged ≥65 years should undergo cervical cancer screening. The relevance of HPV or Cytology test alone or co-test for screening should be evaluated in this population.

Through the wide adaptation of next-generation sequencing (NGS) technology within clinical practice, molecular profiling of the tumor has been the principal component of personalized treatment. In our study, we have generated a large collection of cancer genomes on East Asian epithelial ovarian carcinoma (EOC) patients and demonstrate the feasibility and utility of NGS platforms to explore the dynamic interrelations of major cancer driver alterations and their impacts on clinical prognosis and management. A total of 652 EOC patients have undergone clinical NGS panels to determine the prevalence of germline and somatic mutations. Notably, TP53 was the most frequently altered event (73%), followed by both BRCA1 and BRCA2 (22% each) and MYC (19%) through pan-EOC analysis. When analyzed based on individual histopathological levels, TP53 mutation was highly dominant in high-grade serous and mucinous histology, whereas mutations in PIK3CA and ARID1A were mostly observed in clear cell carcinoma, and KRAS, BRAF, and CDKN2A mutations were enriched in endometrioid, low-grade serous, and mucinous tumors, respectively. The network-based probabilistic model showed significant co-occurrences of TP53 with BRCA1 and ALK with BRCA2, NOTCH1, and ROS1, whereas mutual exclusivity of TP53 with KRAS and PIK3CA was evident. Furthermore, we utilized machine-learning algorithms to identify molecular correlates that conferred increased sensitivity to platinum and olaparib treatments including somatic mutations in BRCA1, ATM, and MYC. Conversely, patients with ALK mutation were considerably resistant to both treatment modalities. Collectively, our results demonstrate the clinical feasibility of prospective genetic sequencing to facilitate personalized treatment opportunities for patients with EOC.

Hysterectomy remains a frequent gynecologic surgery, although its rates have been decreasing. The aim of this study was to investigate whether socioeconomic status affected the risk of hysterectomy in Korean women. This prospective cohort study used epidemiologic data from 2001 to 2016, from the Korean Genomic and Epidemiology Study (KoGES). Multivariate logistic regression analyses were performed to estimate the association between household income or education level and hysterectomy. Among 5272 Korean women aged 40−69 years, 720 who had a hysterectomy and 4552 controls were selected. Variable factors were adjusted using logistic regression analysis (adjusted model). Adjusted odds ratios (aORs) for insurance type and hysterectomy were not statistically significant. The aOR was 1.479 (95% confidence interval (CI): 1.018−2.146, p < 0.05) for women with education of high school or lower compared to college or higher. Women whose monthly household income was
RESUMO
The accuracy of colposcopic diagnosis depends on the skill and proficiency of physicians. This study evaluated the feasibility of interpreting colposcopic images with the assistance of artificial intelligence (AI) for the diagnosis of high-grade cervical intraepithelial lesions. This study included female patients who underwent colposcopy-guided biopsy in 2020 at two institutions in the Republic of Korea. Two experienced colposcopists reviewed all images separately. The Cerviray AI® system (AIDOT, Seoul, Korea) was used to interpret the cervical images. AI demonstrated improved sensitivity with comparable specificity and positive predictive value when compared with the colposcopic impressions of each clinician. The areas under the curve were greater with combined impressions (both AI and that of the two colposcopists) of high-grade lesions, when compared with the individual impressions of each colposcopist. This study highlights the feasibility of the application of an AI system in cervical cancer screening. AI interpretation can be utilized as an assisting tool in combination with human colposcopic evaluation of exocervix.
