Abstract

PurposeWe performed an E-survey to evaluate the practice patterns in debulking surgery for advanced ovarian cancer in Asia. MethodsWe designed a questionnaire, including 50 questions related to debulking surgery for advanced ovarian cancer. The questionnaire was sent to Gynecologic Oncologic Groups in Asia from December 2016 to February 2017. ResultsA total of 253 gynecologic oncologists from Japan (58.9%), the Republic of Korea (19%), Taiwan (12.6%), and the other counties including China (7.5%), Malaysia (0.8%), Indonesia (0.8%), and Thailand (0.4%) participated in this E-survey. The median number of debulking surgeries per year was 20, and 46.8% of the respondents preferred <1 cm as the criterion for optimal debulking surgery (ODS). The most common barrier and surgical finding precluding ODS were performance status (74.3%) and disease involving the porta hepatis (71.5%). Moreover, 63.2% had a fellowship program, and only 15% or less had opportunities to receive additional training courses in general, thoracic, or urologic surgery. The median percentage of patients receiving neoadjuvant chemotherapy (NAC) was 30%, and the achieved rate of ODS in primary debulking surgery (PDS) and interval debulking surgery (IDS) was 65% and 80%, respectively. Most of the respondents required three to 6 h for PDS (48.6%) and IDS (58.9%). Moreover, more than 50% depended on ultra-radical surgery conducted by specialists. ConclusionsThe ODS criteria are relatively lenient with a preference for NAC in 30% of the respondents in Asia. This trend might be associated with the dependence on aggressive surgery performed by specialists.
