e16127 Background: There are different views on the scope of indications for surgical treatment of HCC worldwide. Unlike the Barcelona Clinic Liver Cancer, the European Association for Study of the Liver, and the American Association for the Study of Liver Diseases which recommend surgical resection as the first choice only for early HCC, it is also recommended as the first treatment for selected patients with intermediate or advanced HCC in China. However, in any case, postoperative recurrence is an important issue affecting the long-term survival of HCC patients, and to date, there is no globally recognized treatment algorithm for adjuvant therapy. We performed a survey to understand the patient characteristics and clinical status of hepatobiliary surgeons’ decision aids for adjuvant treatment. Methods: This survey was conducted among senior hepatobiliary surgeons who work at high-volume hospitals in China. Surgeons were asked to fill out an online questionnaire by scanning the QR code. Results: From September to November 2021, 511 surgeons from 55 cities responded. Among them, 70.3% worked in general hospitals, 26.8% in cancer hospitals, and 2.9% in integrative medicine hospitals. The majority of the institutions were tertiary hospitals (91.2 %). When determining whether a patient was suitable or not for adjuvant therapy, surgeons mainly considered tumor factors (chosen by 92.8% and 81.6%) and patient factors (chosen by 80.8% and 75.3%). The analysis showed that the patients whom surgeons considered for adjuvant therapy had one or more of the following characteristics: Tumor factors including China liver cancer (CNLC) stage Ia-IIIb (preoperative), R1 resection, Child-Pugh A or B liver function, well recovery from surgery, presence of ≥1 high-risk recurrence factors (i.e. microvascular invasion, macrovascular tumor thrombus, and hilar lymph node metastasis); Patient factors which were hepatocarcinoma-related medical history (e.g., HBV/HCV) and affordability. Most surgeons used targeted therapy (83.8%, mainly anti-angiogenic multi-kinase inhibitors), TACE (72.8%), or combination therapy (60.3%, mainly targeted drugs combined with immunotherapy or TACE) as adjuvant therapy. When asked to choose the two most related factors impacting treatment compliance, 52.1% chose patients' financial status, and 51.7% considered adverse reactions. Less adverse reactions (71.0% of surgeons), better efficacy (66.7%), and a higher reimbursement ratio (53.3%) were the top 3 unmet need for future adjuvant therapy. Conclusions: This survey presented a patient portrait that Chinese hepatobiliary surgeons considered for adjuvant therapy and the practice patterns in adjuvant therapy for HCC. However, the patient group that can benefit from adjuvant therapy remains to be explored and validated in prospective clinical studies.
