What this trial studies

This clinical study evaluates the safety and efficacy of a combination treatment involving surufatinib, temozolomide, and S-1 as a first-line therapy for patients with advanced neuroendocrine tumors. It is a prospective, open-label, single-center study that aims to enroll patients who have not previously received systemic therapy for their condition. Participants will be monitored for measurable lesions and overall health status throughout the treatment period.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with advanced neuroendocrine tumors.

How similar studies have gone: While this specific combination has not been widely tested, similar approaches in treating neuroendocrine tumors have shown promise in other studies.
