A global comparative study on MDT practices in the management of hepatocellular carcinoma in high-income countries (HICs) and low- and middle-income countries (LMICs).

562 Background: As the sixth most common malignancy worldwide, hepatocellular carcinoma (HCC) accounted for 4.7% of all new cancer diagnoses in 2022. Low- and middle-income countries seem to bear a disproportionate burden of the disease, with over 50% of new HCC cases estimated to occur in China and Africa. Research on multidisciplinary team (MDT) practices in these regions is limited. The objective of this study is to compare MDT practices in the management of HCC in HICs and LMICs. Methods: Data on MDT practices from hospitals that manage HCC in Italy, Spain, Switzerland, Germany, Denmark, Canada and the USA, representing HICs, and in China, South Africa and Egypt, representing LMICs were collected through virtual semi-structured interviews and workshops. Results: Ten key areas of differences were identified (Table 1) that could be categorized as organizational/regulatory or clinical. In HIC institutions, the focus currently is on optimizing MDTs as standard of care approach accessible to all patients with HCC; MDT principles are often integrated into national policies. In LMICs, emphasis is on establishing MDTs and expanding their capacity; patient access to MDT care is not a mandatory requirement, nor regulated in national policy. Of note, LMICs are seeking early technology adoption to overcome some potential barriers to MDT interactions; online formats are more often explored to facilitate participation and AI-assisted diagnostic tools are explored to compensate for absence of radiologists. Absence of screening and surveillance for early detection in HCC is more common in LMICs, and therefore likely that patients more often present with advanced stage disease. Also, with limited diagnostic modalities, diagnostic work-up and staging may be sub-optimal. Conclusions: Significant variation exists in HCC MDT practices between HICs and LMICs. The ultimate goal of this study is to develop a format for clinical MDTs that will facilitate interaction between HICs and LMICs. Consideration for the differences highlighted above is crucial for the development of this concept. 10 key areas highlighting differences identified between HICs and LMICs. MDT development direction: Standard of Care for all patients vs. specific session for complex cases National/regional regulatory requirements Institutionalizing MDT principles MDT composition (specialists) Use of digital tools Reimbursement Access to therapeutic options Stage presentation of HCC patients Use of clinical staging Patient follow-up after MDT discussion
