Outcome Measures

Primary Outcomes (1)

ORR
It refers to the proportion of patients whose tumors have shrunk to a certain amount and maintained for a certain period of time, including CR and PR cases. Solid tumor response assessment criteria (RECIST 1.1 criteria) were used to evaluate objective tumor response. Participants had to have a measurable tumor lesion at baseline, and response criteria were classified as complete response (CR), partial response (PR), stable disease (SD), and disease progression (PD) according to RECIST 1.1 criteria.

Sintilimab + Surufatinib + EP

Sintilimab: 200mg intravenously administered on day 1; Surufatinib: 200mg/ day orally, taken continuously; Etoposide: 1, 2, 3 days of continuous administration, 100mg/m2, intravenous infusion; Cisplatin: 75mg/m2 on day 1, or 25mg/m2 on day 1, 2, and 3, intravenous infusion;

Drug: Sintilimab，Surufatinib

Interventions

Sintilimab，SurufatinibDrug

Based on the standard EP regimen, the combination of surufatinib (anti-angiogenic therapy) and sintilimab (PD-1 inhibitor) were used among patients with advanced gastric neuroendocrine carcinoma.
