#4564 Vasculogenic mimicry in neuroendocrine tumour across different primary sites

Introduction: Anti-angiogenesis treatments targeting VEGFRs, including Surufatinib and Cabozantinib, etc. showed better efficacy for pancreatic neuroendocrine tumours (NET) than NET of other primary sites. Recent clinical trial targeting tumour necrosis factor receptor-associated protein-1, leading to inhibition of vasculogenic mimicry (VM) showed contrary results to current VEGFRs-targeted treatments. However, VM of NET across different primary sites are yet to be understood.

#4494 Efficacy and safety of surufatinib in combination with CAPTEM for patients with advanced G2/G3 NETs: Updated results from a single-arm, phase II study

Introduction: Limited options exist for advanced G2/G3 NETs. While combined anti-angiogenic and chemotherapy has shown improved effect, the efficacy of surufatinib combined with CAPTEM for NETs remains under-explored.

#4427 Surufatinib combined with hepatic artery infusion chemotherapy (HAIC) as second-line and maintenance therapy for neuroendocrine carcinoma with liver metastases: A single-arm, open-label, single-centre phase II clinical study (SuHaNec)

Introduction: Neuroendocrine carcinoma (NEC) is rare and highly aggressive, and liver metastasis leads to worse outcomes for patients (pts) with limited treatment options and poor prognosis. Surufatinib (SUR) exhibited promising antitumour activity in neuroendocrine neoplasms.

#4399 Updated data from a single-arm, open-label, multicentre clinical study on the efficacy and safety of surufatinib combined with EP regimen and serplulimab in first-line treatment of NEC

Introduction: NEC is an aggressive neuroendocrine neoplasm with limited treatment options. Surufatinib (SUR), a kinase inhibitor targeting VEGFRs, FGFR-1, and CSF-1R, improves vascular normalisation and tumour microenvironment, synergising with chemo- and immunotherapy.
