Chemotherapy response score no longer predicts survival outcomes in high-grade serous ovarian cancer patients with BRCA mutation and/or maintenance therapy.

OBJECTIVE: We aimed to revalidate the chemotherapy response score (CRS) system as a prognostic factor for ovarian cancer patients with breast cancer gene (BRCA) mutations or those receiving frontline poly-ADP ribose polymerase (PARP) inhibitors or bevacizumab as maintenance therapy. METHODS: A retrospective analysis was performed using medical records of patients with high-grade serous carcinoma who received neoadjuvant chemotherapy followed by interval debulking surgery between January 2007 and December 2021 at 5 tertiary medical institutions in South Korea. At each hospital, pathologists independently assessed each slide of omental tissues obtained from surgery using the CRS system. Progression-free survival (PFS) and overall survival (OS) values were obtained using Kaplan-Meier analysis to evaluate the effect of BRCA mutation, maintenance therapy, and CRS on survival time. RESULTS: Of 466 patients, BRCA mutations were detected in 156 (33.5%) and 131 (28.1%) were treated with maintenance therapy; 98 (21.0%) and 42 (9.0%) were treated with PARP inhibitors or bevacizumab, respectively. Patients with CRS3 had significantly longer PFS than those with CRS1 or 2 (24.7 vs. 16.8 months, p<0.001). However, there was no significant difference in PFS improvement between CRS3 patients and those with CRS1 or 2 with BRCA mutation (22.0 vs. 19.3 months, p=0.193). Moreover, no significant PFS prolongation was observed in CRS3 patients compared to CRS1 or 2 patients treated with PARP inhibitors or bevacizumab (24.3 vs. 22.4 months, p=0.851; 27.5 vs. 15.7 months, p=0.347, respectively). CONCLUSION: CRS may not be a prognostic factor in patients with BRCA mutations and those receiving frontline maintenance therapy.

Major clinical research advances in gynecologic cancer in 2023: a tumultuous year for endometrial cancer.

In the 2023 series, we summarized the major clinical research advances in gynecologic oncology based on communications at the conference of Asian Society of Gynecologic Oncology Review Course. The review consisted of 1) Endometrial cancer: immune checkpoint inhibitor, antibody drug conjugates (ADCs), selective inhibitor of nuclear export, CDK4/6 inhibitors WEE1 inhibitor, poly (ADP-ribose) polymerase (PARP) inhibitors. 2) Cervical cancer: surgery in low-risk early-stage cervical cancer, therapy for locally advanced stage and advanced, metastatic, or recurrent setting; and 3) Ovarian cancer: immunotherapy, triplet therapies using immune checkpoint inhibitors along with antiangiogenic agents and PARP inhibitors, and ADCs. In 2023, the field of endometrial cancer treatment witnessed a landmark year, marked by several practice-changing outcomes with immune checkpoint inhibitors and the reliable efficacy of PARP inhibitors and ADCs.

Clinical practice guidelines for cervical cancer: the Korean Society of Gynecologic Oncology guidelines.

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.

Immune checkpoint inhibitors with chemotherapy for primary advanced mismatch repair-deficient endometrial cancer: A cost-effectiveness analysis.

OBJECTIVE: The addition of immune checkpoint inhibitors (ICIs), pembrolizumab or dostarlimab, to paclitaxel and carboplatin (TC) has shown better response rates and survival outcomes for patients with primary advanced mismatch repair-deficient (MMRd) endometrial cancer (EC) in NRG-GY018 and RUBY, respectively. Nonetheless, the high cost of ICIs remains a major concern when implementing this strategy in the real world. This study aimed to determine the cost-effectiveness of pembrolizumab and dostarlimab with chemotherapy compared to TC for primary advanced MMRd EC. METHODS: We developed a Markov model including 6600 patients with primary advanced MMRd EC to simulate treatment outcomes. The initial decision points in the model were treatment with pembrolizumab with TC (PEM-TC), dostarlimab with TC (DOS-TC), and TC. Model probabilities, costs, and health utility values were derived with assumptions from published literature. Effectiveness was determined as average quality-adjusted life years (QALYs) gained. The primary outcome was the incremental cost-effectiveness ratio (ICER). RESULTS: TC was the least costly strategy, whereas PEM-TC was the most effective strategy for primary advanced MMRd EC. TC was cost-effective based on a willingness-to-pay (WTP) threshold of $100,000/QALY compared with PEM-TC (ICER, $377,718/QALY), and DOS-TC exhibited absolute dominance (ICER, $401,859/QALY). PEM-TC was cost-effective when the cost of pembrolizumab 200 mg was reduced to $4361 (61% reduction). PEM-TC was selected in 16.5% with a WTP threshold of $300,000/QALY, but in <1% with a WTP threshold range of $100,000-200,000/QALY. CONCLUSION: PEM-TC can become cost-effective for primary advanced MMRd EC when the cost of pembrolizumab substantially decreases.

Robot-assisted versus conventional laparoscopic surgery for endometrial cancer: long-term comparison of outcomes.

Objective: There is a lack of multi-institutional large-volume and long-term follow-up data on comparisons between robot-assisted surgery and conventional laparoscopic surgery. This study compared the surgical and long-term survival outcomes between patients who underwent robot-assisted or conventional laparoscopic surgery for endometrial cancer. Methods: We retrospectively reviewed the data of patients from five large academic institutions who underwent either robot-assisted or conventional laparoscopic surgery for the treatment of endometrial cancer between 2012 and 2017, ensuring at least 5 years of potential follow-up. Intra- and postoperative outcomes, long-term disease-free survival, and overall survival were compared. Results: The study cohort included 1,003 unselected patients: 551 and 452 patients received conventional laparoscopic and robot-assisted surgery, respectively. The median follow-up duration was 57 months. Postoperative complications were significantly less likely to occur in the robot-assisted surgery group compared to the laparoscopic surgery group (7.74% vs. 13.79%, P = 0.002), primarily limited to minor complications. There were no significant differences in survival: 5-year disease-free survival was 91.2% versus 90.0% (P = 0.628) and overall survival was 97.9% versus 96.8% (P = 0.285) in the robot-assisted and laparoscopic surgery cohorts, respectively. Cox proportional hazard regression models demonstrated that the mode of surgery was not associated with disease-free survival (hazard ratio, 0.897; confidence interval, 0.563-1.429) or overall survival (hazard ratio, 0.791; confidence interval, 0.330-1.895) after adjusting for confounding factors. Conclusion: Robot-assisted surgery for endometrial cancer demonstrates comparable long-term survival outcomes and a reduced incidence of postoperative minor complications when compared to conventional laparoscopic surgery.

Pathological findings and long-term prognosis in Korean BRCA1/2 mutation carriers undergoing risk-reducing salpingo-oophorectomy.

OBJECTIVE: Our study aimed to evaluate the incidence of pathological findings in asymptomatic Korean patients with BRCA1/2 pathogenic variants who underwent risk-reducing salpingo-oophorectomy and to assess their long-term prognosis. METHODS: We retrospectively analyzed the medical records of patients with a germinal BRCA1/2 pathologic variant who had undergone risk-reducing salpingo-oophorectomy at Asan Medical Center (Seoul, Korea) between January 2013 and December 2020. All pathologic reports were made based on the sectioning and extensively examining the fimbriated end of the fallopian tube (SEE/FIM) protocol. RESULTS: Out of 243 patients who underwent risk-reducing salpingo-oophorectomy, 121 (49.8%) had a BRCA1 mutation, 119 (48.9%) had a BRCA2 mutation, and three (1.2%) had both mutations. During the procedure, four (3.3%) patients with a BRCA1 mutation were diagnosed with serous tubal intraepithelial carcinoma (STIC) or serous tubal intraepithelial lesion (STIL), and another four patients (3.3%) were diagnosed with occult cancer despite no evidence of malignancy on preoperative ultrasound. In the BRCA2 mutation group, we found one (0.8%) case of STIC, but no cases of STIL or occult cancer. During the median follow-up period of 98 months (range, 44-104) for STIC and 54 months (range, 52-56) for STIL, none of the patients diagnosed with these precursor lesions developed primary peritoneal carcinomatosis. CONCLUSIONS: Risk-reducing salpingo-oophorectomy, in asymptomatic Korean patients with BRCA1/2 pathogenic variants, detected ovarian cancer and precursor lesions, including STIC or STIL. Furthermore, our follow-up period did not reveal any instances of primary peritoneal carcinomatosis, suggesting a limited body of evidence supporting the imperative need for adjuvant treatment in patients diagnosed with these precursor lesions during risk-reducing salpingo-oophorectomy.

Application of preoperative fluorodeoxyglucose-PET/CT parameters for predicting prognosis of high-grade neuroendocrine cervical cancer.

OBJECTIVE: High-grade neuroendocrine cervical cancer (HGNECC) is a rare and aggressive cervical cancer subtype. In this study, we aimed to evaluate the prognostic value of fluorodeoxyglucose-PET/computed tomography (CT) parameters for HGNECC. MATERIALS AND METHODS: This single-center retrospective study included 29 patients with HGNECC who underwent fluorodeoxyglucose-PET/CT scan followed by surgery between 2006 and 2016. RESULTS: The median follow-up period was 40 (range, 4-184) months. After surgery, the resection margins were tumor-negative in 28 patients (96.6%), 8 (27.6%) patients had parametrial tumor invasion, and 7 patients (24.1%) tested positive for lymph node metastasis. The tumor recurred in 20 patients (69%) and 18 patients (62.1%) died during the observation period. In the univariate analyses, age and total lesion glycolysis (TLG) were associated with worse disease-free survival (DFS) (age, hazard ratio 1.056, 95% CI 1.014-1.100, P  = 0.009; TLG2.5, hazard ratio 1.003, 95% CI 1-1.006, P  = 0.033; and TLG3.0, hazard ratio 1.003, 95% CI 1-1.006, P  = 0.034). In the multivariate analyses, older age and higher TLG3.0 were identified as independent poor prognostic factors for DFS (age, hazard ratio 1.058, 95% CI 1.014-1.104, P  = 0.009; TLG3.0, hazard ratio 1.004, 95% CI 1-1.007, P  = 0.033), while resection margin involvement was identified as an independent factor to predict poor overall survival (hazard ratio 20.717, 95% CI 1.289-332.964, P  = 0.032). CONCLUSION: Among the preoperative fluorodeoxyglucose-PET/CT parameters, TLG3.0 may be useful for predicting DFS in patients with HGNECC.

Outcomes and prognostic factors of surgically treated extramammary Paget's disease of the vulva.

OBJECTIVE: Extramammary Paget's disease (EMPD) of the vulva is a rare disease which predominantly presents in postmenopausal Caucasian women. As yet, no studies on Asian female patients with EMPD have been performed. This study aimed to identify the clinical features of patients with vulvar EMPD in Korea, and to evaluate the risk factors of recurrence and postoperative complications in surgically treated EMPD. METHODS: We retrospectively reviewed 47 patients with vulvar EMPD who underwent wide local excision or radical vulvectomy. The clinical data and surgical and oncological outcomes following surgery were extracted from medical records and analyzed. Univariate and multivariate analyses for predicting recurrence and postoperative complications were performed. RESULTS: 21.3% of patients had complications after surgery, and wound dehiscence was the most common. 14.9% of patients experienced recurrence, and the median interval to recurrence from initial treatment was 69 (range 33-169) months. Vulvar lesions larger than 40 mm was the independent risk factor of postoperative complications (odds ratio [OR]=7.259; 95% confidence interval [CI]=1.545-34.100; p=0.012). Surgical margin status was not associated with recurrence in surgically treated vulvar EMPD patients (OR=0.83; 95% CI=0.16-4.19; p=1.000). CONCLUSION: Positive surgical margin is a frequent finding in the patients with vulvar EMPD, but disease recurrence is not related with surgical margin status. Since EMPD is a slow growing tumor, a surveillance period longer than 5 years is required.

Surgical technique of two-step pelvic and para-aortic sentinel lymph node mapping in early-stage endometrial cancer: laparoscopic, robotic, and open method.

Since sentinel lymph node mapping in endometrial cancer is becoming more widely used, the need of standardizing surgical technique is growing [1, 2]. The objective of this surgical video is to describe the procedure of two-step pelvic and para-aortic sentinel lymph node mapping using indocyanine green and fluorescent camera in endometrial cancer, in three versions of surgical modality of laparoscopic, robotic, and open laparotomy. The patients in the surgical video are diagnosed with biopsy-proven endometrial cancer in its early stage determined by the preoperative imaging study. After collecting washing cytology, bilateral salpinges were clamped with Endo Clip™ to minimize tumor spillage. Gauze packing in posterior cul-de-sac was done to minimize the spillage of indocyanine green dye during paraaortic sentinel lymph node mapping. Indocyanine green dye was injected in bilateral uterine fundus, to detect isolated paraaortic sentinel lymph node pathway. After bilateral paraaortic sentinel lymph node was sampled, cervical injection of Indocyanine green dye was done in 3 o'clock and 9 o'clock directions, both superficially and deeply, 2 mL in each side. After dissecting off the obliterated umbilical ligament, para-vesical and para-rectal spaces were developed. The ureter, uterine artery, and internal and external iliac vessels were identified before bilateral pelvic sentinel lymph nodes were sampled. Asan Medical Center's Institutional Review Board exempted this project. Sentinel paraaortic and pelvic lymph nodes were successfully harvested by two-step method of sentinel lymph node mapping through laparoscopic, robotic, and open laparotomy methods. This surgical video provides specific steps of pelvic and para-aortic sentinel lymph node mapping.

A prospective randomized controlled trial evaluating the safety and efficacy of patient blood management program in patients with gynecologic cancer (KGOG 4011/PBM).

BACKGROUND: Gynecologic cancer has a high frequency of anemia, which is associated with increased morbidity and mortality. Blood transfusion is used to correct anemia, but carries its own side effects and problems in the blood supply have been emerging. As such, methods other than transfusion are needed to correct anemia in patients with cancer. PRIMARY OBJECTIVE: To determine whether intravenous administration of high-dose iron supplements before and after surgery as a patient blood management program is helpful in correcting anemia and reducing the frequency of transfusion in patients with gynecologic cancer. STUDY HYPOTHESIS: Patient blood management will reduce the transfusion rate by up to 25%. TRIAL DESIGN: This prospective, multicenter, interventional, randomized controlled study will consist of three steps. In step 1, the safety and effectiveness of patient blood management for surgical patients before, during, and after surgery will be evaluated. In steps 2 and 3, the safety and effectiveness of patient blood management in patients before, during, and after adjuvant radiation therapy and chemotherapy will be evaluated. MAJOR INCLUSION/EXCLUSION CRITERIA: Patients who are diagnosed with gynecologic cancer (ie, endometrial cancer, cervical cancer, ovarian cancer) and scheduled for surgery will be included and their iron deficiency status will be assessed. Only those with a pre-operative hemoglobin level of 7 g/dL or higher will be included. Patients who underwent neoadjuvant chemotherapy or pre-operative radiation therapy will be excluded. Also, patients with serum ferritin >800 ng/mL or transferrin saturation >50% on serum iron panel tests will be excluded. PRIMARY ENDPOINT: Rate of transfusion within 3 weeks after surgery. SAMPLE SIZE: Eligible participants will be randomly assigned in a 1:1 ratio (167 patients each) into the patient blood management group and the conventional management group. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Patient recruitment will be completed by mid-2025, and management and follow-up will be completed by the end of 2025. TRIAL REGISTRATION NUMBER: NCT05669872.

Laparo-endoscopic single-site versus conventional laparoscopic surgery for early-stage endometrial cancer: A randomized controlled non-inferiority trial.

OBJECTIVE: To evaluate the feasibility and safety of laparo-endoscopic single-site surgery (LESS) compared with conventional laparoscopic surgery (CLS) for early-stage endometrial cancer. METHODS: Patients with clinical stage IA, IB, grade 1-3 endometrial cancer were randomly assigned to undergo LESS or CLS. The primary endpoint was the non-inferiority of LESS to CLS in terms of operation time and the number of resected pelvic lymph nodes. We set the non-inferior margin of the operation time as within 15% (24 min) and the number of resected pelvic lymph nodes as within 20% (5.2 lymph nodes). RESULTS: There was no significant difference between the LESS group (n = 53) and the CLS group (n = 54) in terms of age, weight, body mass index, parity, menopausal status, history of abdominal surgery, and preoperative CA-125 levels. The total operation time was comparable between the two groups. On average, 4.6 fewer pelvic lymph nodes were retrieved in the LESS group, which was within the non-inferiority margin. There were no significant differences in the incidence of intra- and postoperative complications, estimated blood loss, and postoperative hospital stay between the two groups. After a median follow-up time of 34 months (range, 2-242), the progression-free survival rates were 96.2% and 98.1% (P = 0.55) in the LESS group and the CLS group, and the overall survival rates were 98.1% and 100.0% (P = 0.31), respectively. CONCLUSION: LESS surgical staging was non-inferior to CLS and had acceptable feasibility, safety, and efficacy for the surgical management of early-stage endometrial cancer. TRIAL REGISTRATION: Clinicaltrial.gov identifier number: NCT01679522.

Major clinical research advances in gynecologic cancer in 2022: highlight on late-line PARP inhibitor withdrawal in ovarian cancer, the impact of ARIEL-4, and SOLO-3.

In the 2022 series, we summarized the major clinical research advances in gynecologic oncology based on communications at the conference of Asian Society of Gynecologic Oncology Review Course. The review consisted of 1) Ovarian cancer: long-term follow-up data, new poly (ADP-ribose) polymerase (PARP) inhibitors, overall survival (OS) issues with PARP inhibitor monotherapy, hyperthermic intraperitoneal chemotherapy, immunotherapy, and antibody-drug conjugate; 2) Cervical cancer: surgery in early stage disease, therapy for locally advanced stage and advanced, metastatic, or recurrent setting; and 3) Corpus cancer: follow-up regimen, immune checkpoint inhibitor, WEE1 inhibitor, selective inhibitor of nuclear export. A special note was made on the withdrawal of PARP inhibitor from the market for heavily pretreated ovarian cancer patients based on the final OS results of ARIEL-4 and SOLO-3 due to concerns of increased risk of death.

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).

BACKGROUND: 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. METHODS: 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. TRIAL REGISTRATION: ClinicalTrials.gov Identifier (NCT number): NCT04845828.

Impact of bevacizumab and secondary cytoreductive surgery on survival outcomes in platinum-sensitive relapsed ovarian clear cell carcinoma: A multicenter study in Korea.

OBJECTIVE: This study investigated survival outcomes for platinum-sensitive relapsed ovarian clear cell carcinoma (OCCC) by treatment method. METHODS: OCCC patients with platinum-sensitive recurrence that received secondary treatment at five institutions between July 2007 and June 2021 were included. Patient characteristics and survival outcomes were compared according to the use of bevacizumab (BEV) during second-line chemotherapy and secondary cytoreductive surgery (CRS). RESULTS: 138 patients were included. The BEV (n = 36) and non-BEV (n = 102) groups had similar initial FIGO stages and proportions of secondary CRS. The BEV group showed improved progression-free survival (PFS; median, 15.4 vs. 7.5 months; P = 0.042) and overall survival (OS; P = 0.043) compared to the non-BEV group. In multivariate analyses, BEV was identified as an independent prognostic factor for PFS (adjusted hazard ratio [aHR], 0.571; 95% confidence interval [CI], 0.354-0.921; P = 0.022) and OS (aHR, 0.435; 95%CI, 0.195-0.970; P = 0.042). The secondary CRS group (n = 42) had early-stage disease at diagnosis more frequently (P = 0.009) and multi-site metastasis (P < 0.001) at recurrence less frequently than the no surgery group (n = 96). The secondary CRS group showed significantly better PFS (median, 33.7 vs. 7.2 months; P < 0.001) and OS (P < 0.001). Secondary CRS was associated with a significantly improved PFS (aHR, 0.297; 95% CI, 0.183-0.481; P < 0.001) and OS (aHR, 0.276; 95% CI, 0.133-0.576; P = 0.001). The BEV and non-BEV groups showed similar PFS and OS among the patients who underwent secondary CRS. In contrast, the BEV group showed improved PFS and OS among patients who did not undergo surgery. CONCLUSIONS: The use of BEV during second-line chemotherapy and secondary CRS may improve PFS and OS in patients with platinum-sensitive relapsed OCCC. Further prospective studies are warranted.

Major clinical research advances in gynecologic cancer in 2021.

In the 2021 series, we not only summarized the major clinical research advances in gynecologic oncology but also added discussions to every part, based on communications at the conference. A review of cervical cancer included adjuvant treatments such as radiation and chemoradiation (concurrent or sequential) after radical hysterectomy in early cervical cancer, and immune checkpoint inhibitors in advanced, recurrent, and metastatic disease. Ovarian cancer research included studies of secondary cytoreductive surgery in platinum-sensitive recurrent ovarian cancer, and various trials of immune checkpoint inhibitors with or without vascular endothelial growth factor inhibitors and conventional chemotherapy. The rechallenge of poly (ADP-ribose) polymerase inhibitor maintenance in heavily pretreated ovarian cancer were also addressed. For uterine corpus cancer, dostarlimab (anti-programmed cell death protein 1 antibody) alone, or a tyrosine kinase inhibitor in combination with pembrolizumab for advanced, metastatic, or recurrent endometrial cancer were reviewed. The survival differences between the intensive and minimalist follow-up protocols were also described. In this review, we compared salpingectomy with delayed oophorectomy and salpingo-oophorectomy in terms of quality of life in BRCA 1 and 2 pathogenic variant carriers.

Single-Incision versus Multiport Robotic Myomectomy: A Propensity Score Matched Analysis of Surgical Outcomes and Surgical Tips.

We aimed to compare the perioperative outcomes of single-incision robotic myomectomy (SIRM) and multiport robotic myomectomy (MPRM) and provide surgical tips. We retrospectively analyzed the medical records of 462 patients with symptomatic leiomyoma who underwent MPRM or SIRM between March 2019 and April 2021. Demographic characteristics and surgical outcomes, including the total operative time (OT), estimated blood loss (EBL), and surgical complication rate, were compared between the two groups. Patients in the SIRM group had lower a body mass index and rate of previous pelvic surgery and were younger than those in the MPRM group. The myoma type was not different between groups; however, the MPRM group had larger, and more myomas than the SIRM group. After propensity score matching, these variables were not significantly different between the groups. The total OT, EBL, difference in hemoglobin levels, transfusion rate, and postoperative fever were not different between the groups. No postoperative complications occurred in the SIRM group. In the MPRM group, one patient needed conversion to laparotomy, and two patients had postoperative complications (umbilical incisional hernia and acute kidney injury). In conclusion, both MPRM and SIRM are feasible and effective surgical options for symptomatic myomas with cosmetic benefits and minimal risk of laparotomy conversion.

The Clinical Significance and Utility of HPV-DNA Testing in Korean Women with Atypical Glandular Cells in Cervical Pap Tests: An Analysis of 311 Cases at a Single Institution.

The aim of this study is to analyze the correlation between clinically significant histologic results and HPV in women with AGC in pap test. Of the 311 women confirmed as AGC, 111 women (35.7%) was identified as positive for HPV. In the AGC analysis, cervical lesions were significantly more common in HPV positive group compared to HPV negative group (61.2 vs. 10.5%, p < 0.001). In contrast, endometrial lesions were not associated with HPV infection (8.1 vs. 4.5%, p = 0.12). The HPV-DNA testing in women with AGC may be a useful tool for predicting clinically significant cervical lesions.

Major clinical research advances in gynecologic cancer in 2020.

In 2020 series, we summarized the major clinical research advances in gynecologic oncology with providing representative figures of the most influential study for 1 of each 3 gynecologic cancers: cervix, ovary, and uterine corpus. Review for cervical cancer covered targeted agents and immune checkpoint inhibitors, adjuvant radiation therapy or concurrent/sequential chemoradiation therapy after radical hysterectomy in early cervical cancer, radical surgery in early cervical cancer; and prevention and screening. Ovarian cancer research included studies of various combinations of poly (ADP-ribose) polymerase inhibitors with chemotherapy, immune checkpoint inhibitors, and/or vascular endothelial growth factor inhibitors according to the clinical setting. For uterine corpus cancer, molecular classification upon which the decision of adjuvant treatments might be based, World Health Organization recommendation of 2-tier grading system (low grade vs. high grade), sentinel lymph node assessment and ovarian preservation in clinically early-stage endometrial cancer were reviewed. Molecular targeted agents including immune checkpoint inhibitors which showed promising anti-tumor activities in advanced/recurrent endometrial cancer were also included in this review.
