Objective:
Gynecologic oncology is undergoing rapid development with continuous advances in treatment strategies, surgical techniques, and clinical research. Training programs must keep pace by providing future specialists with the necessary surgical skills and a solid understanding of evolving practices. This study aimed to examine the current state of gynecologic oncology training in Asia and to identify key challenges and opportunities for improvement.
Methods:
A descriptive survey was conducted in October 2023 under the leadership of the Education Committee of the Asian Society of Gynecologic Oncology (ASGO). Key stakeholders involved in clinical training and policy-making from eight countries and regions (China, Hong Kong SAR, India, Japan, the Philippines, South Korea, Taiwan, and Thailand) responded to an online questionnaire assessing the structure and quality of their national training programs.
Results:
Six of the eight countries/regions have official gynecologic oncology societies.Training duration was three years or more in five regions and two years in the remaining three. Seven reported conducting formal assessments of surgical skills. While five programs offered adequate exposure to minimally invasive surgery, three noted limitations. Satisfaction with research opportunities and overall training quality also varied. The most frequently cited concern was the lack of standardized curricula.
Conclusion
This regional overview reveals notable differences in training approaches across Asia. Standardizing educational frameworks and expanding collaborative initiatives – such as virtual tumor boards, elective rotations, and skills-based workshops – may help address current gaps and strengthen gynecologic oncology training in the region.

Objective:To investigate the incidence, clinical characteristics, and impact of spontaneous portosystemic shunt (SPSS) in patients with liver cirrhosis combined with hepatic encephalopathy (HE).Methods:The basic clinical and follow-up data were retrospectively analyzed for patients diagnosed with cirrhosis combined with HE at Mengchao Hepatobiliary Hospital of Fujian Medical University from January 2017 to December 2022. The patients were divided into large and small SPSS groups and a control group based on the results of abdominal enhanced CT or MRI.The clinical characteristics and outcome differences were compared among the three groups. Kaplan-Meier survival curves were used to compare HE-free survival time and overall survival time among the three groups. The log-rank test was used to compare the differences between groups. Cox regression analysis was used to identify the relevant risk factors affecting HE-free survival time and overall survival time.Results:A total of 223 cases with liver cirrhosis combined with HE were enrolled, including 150 in the SPSS and 73 in the control groups. The incidence rate of SPSS was 67.3% (150/223). The group was divided into small SPSS (79/150, 52.7%) and large SPSS group (71/150, 47.3%) according to the cross-sectional area of the diversion channel. The HE-free survival was shorter in the small and large SPSS groups compared with the control group (35.5 months in the small SPSS group and 21.3 months in the large SPSS group; P<0.001). The HE-free survival time was shorter in the large SPSS than with small SPSS group ( P=0.003). The overall survival time in the small SPSS group and the large SPSS group was shorter compared with the control group (small SPSS group: 39.4 months, large SPSS group: 52.9 months; P<0.001). There was no statistically significant difference in overall survival time between the small SPSS and large SPSS groups ( P=0.700). Cox regression analysis showed that SPSS was an independent risk factor affecting patients' HE-free survival time and overall survival time ( P<0.05). Conclusion:SPSS is more common in patients with liver cirrhosis combined with HE. Patients who combined with SPSS showed significant reductions in both HE-free survival time and overall survival time, especially evident in those with combined large SPSS.

Hepatic encephalopathy (HE) is a kind of neuropsychiatric syndrome caused by acute or chronic liver failure or portosystemic venous shunt (hereinafter referred to as portosystemic shunt), which can lead to the occurrence of functional impairment, personality and behavioral abnormalities, coma, and even death. Most patients with cirrhosis combined with HE have spontaneous portosystemic shunt (SPSS), especially those with recurrent or persistent HE. Internal medicine's current standard of treatment for HE associated with SPSS in cirrhotic patients is unsatisfactory, and even after treatment, recurrent HE episodes may still occur. Although interventional therapy has shown significant results and has been applied in clinical practice for many years for SPSS-associated HE, the number of treatment-related cases is relatively small, and there is a lack of large samples and well-designed research. Currently, interventional therapy for SPSS-associated HE in patients with cirrhosis is still under continuous exploration.
