For patients enrolled in the extended period:
Group 1: vascular rich tumors, including but not limited to neuroendocrine tumors, thymic squamous cell carcinoma and soft tissue Sarcoma, the specific categories are as follows.

Group Intervention Description MSB0254 Injection MSB0254 Injection This experiment will start from 4mg/kg with a dose increase of 3+3, and is planned to be carried out in 5 dose groups, namely 4mg/kg, 8mg/kg (100% increase), 12mg/kg (50% increase), 16mg/kg (33% increase) and 20mg/kg (25% increase).MSB0254 injection was administered intravenously on day 1 and day 15 every 28 days.To collect pharmacokinetic blood samples after repeated administration, MSB0254 injection was not administered on day 1 of the third cycle (C3D1).The observation period of DLT was 28 days after the first administration. An intravenous infusion with concentration 20 mg/kg every 3 weeks (Q3W).
