Impact of the Coronavirus Disease 2019 pandemic on neoadjuvant chemotherapy use in patients diagnosed with epithelial type ovarian cancer.

The Coronavirus Disease 2019 (COVID-19) pandemic posed critical challenges in providing care to ovarian cancer (OC) patients, including delays in OC diagnosis and treatment initiation. To accommodate for delays in OC surgery, the Society of Gynecologic Oncology (SGO) recommended preferential use of neoadjuvant chemotherapy during the pandemic. The purpose of this study was to assess the association of the COVID-19 pandemic with neoadjuvant chemotherapy use in patients diagnosed with OC. This retrospective cohort study included patients diagnosed with stage II-IV ovarian cancer of epithelial subtype between 01/01/2017-06/30/2021 at Kaiser Permanente Southern California (KPSC), a large integrated healthcare system in the United States. Ovarian cancer patients diagnosed between 2017-2020 were identified from KPSC's Surveillance, Epidemiology, and End Results (SEER)-affiliated cancer registry. Patients diagnosed in 2021 were identified from the electronic medical records (EMR) using ICD-10 diagnosis codes, followed by medical chart review to validate diagnosis and extract information on histology and stage at diagnosis. March 4, 2020 was used as the cut-off to define pre-pandemic and pandemic periods. Patients diagnosed with COVID-19 between OC diagnosis and treatment completion were excluded. Data on neoadjuvant chemotherapy use were extracted from the cancer registry and EMR, supplemented by chart review. Modified Poisson regression was used to evaluate the association of the pandemic with neoadjuvant chemotherapy use. Of 566 OC patients, 160 (28.3%) were diagnosed in the pandemic period. Patients diagnosed in the pandemic period were slightly younger (mean age 62.7 vs 64.9 years, p=0.07) and had a higher burden of Charlson comorbidities (p=0.05) than patients diagnosed in pre-pandemic period. No differences in time to treatment initiation were observed by pandemic periods. Neoadjuvant chemotherapy use was documented in 58.7% patients during the pandemic period compared to 47.3% in pre-pandemic period (p=0.01). After adjusting for covariates, patients diagnosed in the pandemic period were 29% more likely to receive neoadjuvant chemotherapy than patients diagnosed in pre-pandemic period [RR(95%CI): 1.29(1.12-1.49)]. Ovarian cancer patients diagnosed in the COVID-19 pandemic were more likely to receive neoadjuvant chemotherapy than patients diagnosed before the pandemic. Future research on patient outcomes and trends in the post-pandemic period are warranted.

Prophylactic Antibiotics before Gynecologic Surgery: A Comprehensive Review of Guidelines.

Surgical site infections (SSIs) refer to infections in the incision, organ, or postoperative space. As common healthcare-associated infections, SSIs correlate with prolonged hospital stay, additional procedures, ICU stay, and higher mortality rates. Around 8-10% of gynecologic surgery patients may experience infectious complications, influenced by microbial contamination, surgical nature, and patient factors. The goal of this narrative review is to compare and merge recommendations from globally published guidelines concerning the utilization of antibiotics in the perioperative phase. A comparative descriptive/narrative review of the guidelines issued by the American College of Obstetrics and Gynecology (ACOG), Society of Obstetricians and Gynecologists of Canada (SOGC), Royal College of Obstetricians and Gynecologists (RCOG), National Institute for Health and Care Excellence (NICE), Royal Australian and New Zealand College of Obstetricians and Gynecologists (RANZCOG), European Society of Gynecologic Oncology (ESGO), Société Française d' Anésthesie et de Réanimation (SFAR), Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), and Hellenic Society of Obstetrics and Gynecology (HSOG) was conducted. For hysterectomy, first/second-generation cephalosporins are suggested, with metronidazole as an option. Laparoscopy without entering the bowel or vagina typically does not require prophylaxis. Uterine evacuation and hysteroscopy may involve doxycycline or azithromycin based on risk factors, whereas, for vulvectomy, cefazolin is recommended. Urogynecology procedures may include cefazolin with metronidazole. In cases of penicillin allergy, cephalosporins are suggested, and, for obese patients, adjusted doses are advised. Additional doses may be needed for prolonged procedures or excessive blood loss. Timing recommendations are 15-60 min before incision, adjusting for specific antibiotics. Clear indications exist for certain surgeries like hysterectomy, termination of pregnancy, and urogynecologic procedures. Conversely, procedures such as intrauterine device insertion, hysteroscopy, and laparoscopy typically do not necessitate antibiotic prophylaxis. For several other procedures, the evidence is inconclusive, while considering dose, timing, and indications can mitigate infectious complications and provide benefits for the healthcare system.

Ovarian cancer management in an ESGO ovarian cancer center of excellence: a systematic case study of the interprofessional and interdisciplinary interaction.

With growing knowledge about ovarian cancer over the last decades, diagnosis, evaluation and treatment of ovarian cancer patients have become highly specialized, and an individually adapted approach should be made in each woman by interdisciplinary cooperation. The present study aims to show the variety and extent of medical specialties involved at our institution according to the European Society of Gynecologic Oncology (ESGO) Quality indicators (QI). A woman, diagnosed with high-grade ovarian cancer, International Federation of Gynecology and Obstetrics (FIGO) class IVb was selected for a single case observational study. The observation period (total=22d) comprised preoperative diagnostic procedures, including imaging, the in-patient stay for cytoreductive surgery, and the postoperative course and case discussion at our interdisciplinary tumor board. Data were obtained by self-reporting and by patient file review. Patient tracking demonstrated an interdisciplinary cooperation of 12 medical specialties [62 physicians (63% male, 37% female)], 8 different types of nursing staff [n=59 (22% male, 78% female)], and 9 different types of perioperative/administrative staff (n=23; male 17,4%, female n=19, 82,6%). Contact with the patient was direct (n=199; 76%) or without face-to-face interaction (n=63; 24%). The present study demonstrates the high diversity of physicians and the affiliated medical staff, as well as interdisciplinary intersections within teams of a specialized hospital. Matching the ESGO QIs, this report underlines the requirement of an adequate infrastructure for the complex management of advanced ovarian cancer patients. Future prospective studies are warranted to evaluate the specific procedures and actions to optimize the interprofessional and interdisciplinary workflows.

Advancements in Endometrial Cancer Research in 2023

Endometrial cancer is one of the most common gynaecological cancers in developed countries, and the incidence is rising significantly. The staging of this disease is evolving from anatomic staging and risk stratification to a more molecular-based stratification. Treatment of endometrial cancer is also evolving. Paclitaxel plus carboplatin is the standard first-line chemotherapy for endometrial cancer; however, there is new evidence that the combination of chemotherapy and immunotherapy has synergistic effects in the treatment of this disease. This article discusses the latest advancements in endometrial cancer research in 2023, including highlights from the Society of Gynecologic Oncology (SGO) Annual Meeting on Women’s Cancers 2023 in March, the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in June, the 24th European Gynaecological Oncology (ESGO) Congress in September and October, and the European Society for Medical Oncology (ESMO) Congress 2023 in October. The article highlights the unprecedented progression-free survival (PFS) data from two Phase III randomised controlled trials evaluating first-line immunotherapy in combination with chemotherapy in patients with advanced or recurrent endometrial cancer: RUBY with dostarlimab, and NRG-GY018 with pembrolizumab, which created a buzz at SGO 2023 in the spring, and stimulated discussion throughout the remainder of the year. The overall survival (OS) results, the clinically meaningful benefits regardless of mismatch repair status, and health-related quality of life (QOL) in these studies are also discussed. Further topics covered in this year-in-review article include the implications of the results from RUBY and NRG-GY018 on first-line treatment and recurrent settings, and the effect of adding a poly adenosine diphosphate ribose polymerase (PARP) inhibitor to immunotherapy–chemotherapy combinations in the Phase III trial, DUO-E. Disparities in endometrial cancer care, research on fertility-sparing, and the importance of the multidisciplinary team (MDT) in endometrial cancer management are also explored. Following the announcement of practice-changing findings from RUBY and NRG-GY018 in March, data presented and published throughout the remainder of 2023 show that research in endometrial cancer continues at a pace.

Germline and somatic testing for ovarian Cancer: An SGO clinical practice statement

Germline and somatic genetic testing have become critical components of care for people with ovarian cancer. The identification of germline and somatic pathogenic variants as well as homologous recombination deficiency can contribute to the prediction of treatment response, prognostic outcome, and suitability for targeted agents (e.g. poly (ADP-ribose) polymerase (PARP) inhibitors). Furthermore, identifying germline pathogenic variants can prompt cascade genetic testing for at-risk relatives. Despite the clinical benefits and consensus recommendations from several organizations calling for universal genetic testing in ovarian cancer, only about one third of patients complete germline or somatic genetic testing. The members of the Society of Gynecologic Oncology (SGO) Clinical Practice Committee have composed this statement to provide an overview of germline and somatic genetic testing for patients with epithelial ovarian cancer, focusing on available testing modalities and options for care delivery.

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

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 platinum-sensitive 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.

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.

Japan Society of Gynecologic Oncology 2022 guidelines for uterine cervical neoplasm treatment.

The Japan Society of Gynecologic Oncology (JSGO) Guidelines 2022 for the Treatment of Uterine Cervical Cancer are revised from the 2017 guideline. This guideline aimed to provide standard care for cervical cancer, indicate appropriate current treatment methods for cervical cancer, minimize variances in treatment methods among institutions, improve disease prognosis and treatment safety, reduce the economic and psychosomatic burden of patients by promoting the performance of appropriate treatment, and enhance mutual understanding between patients and healthcare professionals. The guidelines were prepared through the consensus of the JSGO Guideline Committee, based on a careful review of evidence gathered through the literature searches and the medical health insurance system and actual clinical practice situations in Japan. The guidelines comprise seven chapters and 5 algorithms. The main features of the 2022 revision are as follows: 1) added discussed points at the final consensus meeting; 2) revised the treatment methods based on the International Federation of Gynecology and Obstetrics 2018 staging system; 3) examined minimally invasive surgery based on Laparoscopic Approach to Cervical Cancer trial; 4) added clinical question (CQ) for treatments of rare histological types, gastric type, and small-cell neuroendocrine carcinoma; 5) added CQ for intensity-modulated radiation therapy; 6) added CQ for cancer genomic profiling test; and 7) added CQ for cancer survivorship. Each recommendation is accompanied by a classification of recommendation categories based on the consensus reached by the Guideline Committee members. Here, we present the English version of the JSGO Guidelines 2022 for the Treatment of Uterine Cervical Cancer.

Perspectives of gynecologic oncology fellowship training and preparedness for practice

We aimed to examine the preparedness of recent gynecologic oncology fellowship graduates for independent practice.We conducted a web-based survey study using REDCap targeting Society of Gynecologic Oncology (SGO) members who graduated gynecologic oncology fellowship within the last six years. The survey included 52 items assessing fellowship training experiences, level of comfort in performing core gynecologic oncology surgical procedures and administering cancer-directed therapies. Questions also addressed factors driving participants’ selection of fellowship programs, educational experience, research and preparedness for independent practice. A total of 296 participants were invited to complete the survey. Response rate was 42% with n = 124 completed surveys included for analysis. The highest ranked factor for fellowship selection was fit with program 36% (n = 45). Upon completing fellowship, most were uncomfortable performing ureteral conduit formation 84% (n = 103), ureteroneocystostomy 77% (n = 94), exenteration 68% (n = 83), splenectomy 67% (n = 83) and lower anterior resection 41% (n = 51). Most were comfortable managing intraoperative complications 85% (n = 104) and standard cancer staging procedures (range: 61%–99%). Majority were comfortable providing cancer directed therapies with chemotherapy 99% (n = 123), immunotherapy 84% (n = 104), and poly ADP-ribose polymerase (PARP) inhibitors 97% (n = 120). Upon completing fellowship, 77% (n = 95) report having mentorship that met their expectations during fellowship and 94% (n = 116) felt they were ready for independent practice. Majority of fellowship graduates were prepared for independent practice and felt comfortable performing routine surgical procedures and cancer directed treatment. However, most are not comfortable with ultra-radical gynecologic oncology procedures. Maximizing surgical opportunities during fellowship training and acquiring early career mentorship may help.

Vulvar cancer management and wrangling recurrent disease: A report from the society of gynecologic oncology journal club

The Society of Gynecologic Oncology (SGO) Journal Club webinar series is an open forum that invites national experts to discuss the literature pertaining to important topics in the management of gynecologic cancers. On August 14th, 2023, SGO hosted a journal club focused on the management of upfront and recurrent vulvar cancer. Our discussants included Dr. Brian M Slomovitz from Mount Sinai Medical Center in Miami Beach, Dr. Emi Yoshida from the University of California San Francisco Helen Diller Family Comprehensive Cancer Center, and Dr. Lilian Gien from the University of Toronto Sunnybrook Odette Cancer Center. During the discussion,we reviewed the progression of vulvar cancer surgery from en bloc resection of the vulva and groins, to partial radical vulvectomy and sentinel lymph nodes. We also reviewed the management of node positive vulvar cancer including published and accruing Groningen International Study on Sentinel Nodes in Vulvar Cancer (GROINSS) trials and other sentinel trials from the Gynecologic Oncology Group (GOG). Here we will also review the literature on the management of recurrent vulvar cancer, highlighting current treatment options and ongoing clinical trials. The following is a report of the journal club presentation.

Relationship between Knowledge Level and Attitude with Ovarian Cancer Early Detection Behavior at Ibnu Sina Hospital Makassar

Ovarian cancer is a malignant tumor originating from the ovary with various histological types that can affect all ages, in the early stages of the disease does not show specific clinical symptoms. The Indonesian Society of Gynecologic Oncology recorded 354 cases of ovarian cancer and is the second most common gynecologic cancer. The high mortality rate is due to asymptomatic tumor growth, delayed onset of symptoms, and lack of proper screening so that ovarian cancer is only diagnosed at an advanced stage. Ovarian cancer cases that are recognized and found at an early stage and receive rapid and appropriate treatment and treatment will provide a better life expectancy. Currently, radiologic examinations for ovarian cancer detection include: Ultrasound, CT scan, PET scan, and MRI. This study aims to determine the relationship between the level of knowledge and attitudes with the behavior of early detection of ovarian cancer at Ibnu Sina Hospital Makassar. Research using quantitative descriptive design with cross-sectional design. Of the 60 respondents obtained results based on the category of knowledge level in patients diagnosed with ovarian cancer who have good knowledge as many as 19 respondents (100%), enough as many as 10 (41.7%), less (5.9%) good category attitudes as many as 18 (40.9%), enough 12 (80.0%), less 0 respondents (0.0%). And for the level of knowledge in patients who are not diagnosed with ovarian cancer who have good knowledge 0 respondents (0.0%), enough 14 (58.3%), less knowledge as many as 16 (94.1%), good category attitudes 26 (59.1%), sufficient category attitudes 3 (20.0%), less category attitudes 1 (100.0%). There is a relationship between the level of knowledge and attitude towards ovarian cancer early detection behavior.

Recent Developments in Endometrial Cancer Research Presented at the Society of Gynecologic Oncology (SGO) Annual Meeting 2023: Interviews with Two Key Opinion Leaders

Endometrial cancer is the most common gynaecological malignancy in developed countries, and often presents at an early stage. Paclitaxel plus carboplatin is the standard first-line chemotherapy for endometrial cancer; however, there is new evidence that the combination of chemotherapy and immunotherapy has synergistic effects in the treatment of this disease. For this article, EMJ conducted an interview in August 2023 with two key opinion leaders: Jubilee Brown and Wendel Naumann from Atrium Health Levine Cancer Institute, Charlotte, North Carolina, USA, both of whom have a wealth of experience and expertise in the management of endometrial cancer. The experts gave valuable insights into recent developments in endometrial cancer research as presented at the Society of Gynecologic Oncology (SGO) Annual Meeting on Women’s Cancers 2023, held on 25th–28th March 2023 in Tampa, Florida, USA, and online. Topics discussed included the unprecedented progression-free survival (PFS) data from two Phase III randomised controlled trials evaluating first-line immunotherapy in combination with chemotherapy in patients with advanced or recurrent endometrial cancer, RUBY with dostarlimab, and NRG GY018 with pembrolizumab, which created a buzz at SGO 2023. Clinically meaningful benefit of dostarlimab or pembrolizumab in combination with chemotherapy versus standard-of-care chemotherapy was seen regardless of mismatch repair status in RUBY and NRG-GY018, respectively. Brown and Naumann considered the implications of these results on first-line treatment and recurrent settings, and outlined the management of immune-related adverse events related to immunotherapy-based treatment regimens. The experts also explored key earlier stage studies presented at SGO, and the potential for personalised medicine in endometrial cancer. Finally, Brown and Naumann described what the future of the management of patients with endometrial cancer might look like, which clinical trials are needed, and which advancements in research they would like to see.

Nonsurgical management of early-stage endometrial cancer due to obesity: a survey of the practice patterns of current Society of Gynecologic Oncology members

ObjectiveNonsurgical management for endometrial cancer in patients with class 3 obesity (BMI ≥ 40 kg/m2) is a challenging scenario given lack of consensus on patient selection and treatment options. Our objective was to evaluate trends in practice patterns and physician opinions in the Society of Gynecologic Oncology (SGO) on nonsurgical management of endometrial cancer and complex atypical hyperplasia due to obesity. MethodsAn online survey was sent to all gynecologic oncologist members of the SGO with questions centered on decision-making for nonsurgical approaches for patients with class 3 obesity patients. Fisher’s exact tests were used to assess the associations between offering nonsurgical management and geographic region, practice type, and time in practice. Results255 (19.8 %) members from 6 geographic regions responded, of which 183 (71.8 %) offered primary nonsurgical management of endometrial cancer to patients with class 3 obesity and 72 (28.2 %) do not. The choice to offer initial nonsurgical management did not vary based on geographic region, time in practice or practice type. When asked to select BMI cutoff, the majority (65.2 %) started to offer nonsurgical management was BMI 60–64 kg/m2. Progesterone intrauterine device was the preferred treatment (68.3 %, 125/183). Of those who offered nonsurgical management, 97.3 % (178/183) recommended resampling in 3–6 months. ConclusionPrimary nonsurgical management of endometrial cancer in patients with class 3 obesity is offered by most gynecologic oncologists in SGO. However, almost one-third of gynecologic oncologists indicated they do not offer nonsurgical management for endometrial cancer for obesity alone. Additional data are needed to determine the safety of both approaches in these complex patients.

Executive Summary of the Ovarian Cancer Evidence Review Conference

ABSTRACT Ovarian cancer has the 17th highest incidence among all cancers in the United States; however, it is the deadliest gynecologic cancer and the fifth most common cause of cancer-related death in women in the United States. The Centers for Disease Control and Prevention funded the American College of Obstetricians and Gynecologists (ACOG) to create educational materials for clinicians on the early diagnosis and prevention of gynecologic cancers. This article is an evidence summary based on ACOG's extensive literature review on the early diagnosis and prevention of ovarian cancer. An expert panel was recruited from the Society for Academic Specialists in General Obstetrics and Gynecology and the Society of Gynecologic Oncology to review and summarize evidence from articles published between January 2000 and October 2021. Topics used to frame the literature review included the epidemiology of ovarian cancer, risk factors, prevention and risk reduction, screening strategies and early detection, health disparities, diagnosis and care coordination by primary care providers, and special considerations. The Ovarian Cancer Evidence Review Conference occurred in February 2022 where the expert panel and stakeholder professional and patient advocacy organizations discussed their findings and drafted summaries to develop educational materials. Review of the epidemiology revealed that in 2022 there were 19,880 new cases of ovarian cancer, 12,810 women died of ovarian cancer, 5-year survival is 49.7% and correlates strongly with stage at diagnosis, and fewer than 10% of women with stage 1 disease will have recurrence. Risk factors for ovarian cancer include older age, inactivity, nulliparity, early menarche, late menopause, postmenopausal hormone therapy, genetic mutations such as BRCA1 and BRCA2, and endometriosis. Risk-reducing bilateral salpingo-oophorectomy reduces incidence of ovarian cancer by 80% in BRCA1 and BRCA2 carriers (95% confidence interval, 0.12–0.39) and is recommended by ACOG for women at increased risk of ovarian cancer. Contraception, physical activity, and lactation may help reduce the risk of ovarian cancer. The most common methods studied for screening include transvaginal ultrasonography, bimanual palpation, and measuring tumor marker CA-125. The Risk of Ovarian Cancer Algorithm uses CA-125 and transvaginal ultrasound to estimate the risk of ovarian cancer based on age and change in CA-125; however, it is still being studied, and no established screening method exists for asymptomatic women. Several organizations including ACOG support identifying women at high risk and subsequent genetic counseling. Symptoms of ovarian cancer are nonspecific and include abdominal distention and pain, and while workup should include ultrasonography and CA-125 measurement, no high-quality studies have compared imaging, biomarkers, risk algorithms, or multimodal risk assessment tools for the primary evaluation of patients with high-risk symptoms. Regarding disparities, Black women consistently had worse outcomes compared with their White counterparts, and little evidence regarding other racial and ethnic groups or gender minorities was identified. Finally, care coordination is critical, and ACOG recommends a low bar for referral to a gynecologic oncologist for patients with suspicion of ovarian cancer, which has been shown to increase survival and offer other advantages. This evidence review identifies many research gaps and opportunities for ovarian cancer and provides a high-level educational summary of current best practices in the risk stratification, diagnosis, and prevention of ovarian cancer.
