The combination of surufatinib with neoadjuvant chemo-immunotherapy and definitive concurrent chemoradiotherapy represents a promising new therapeutic strategy that may further improve the prognosis of patients with unresectable locally advanced esophageal squamous cell carcinoma (ESCC). Therefore, we propose to conduct a prospective, single-arm, phase II clinical trial to evaluate the efficacy and safety of this regimen in patients with unresectable, locally advanced ESCC.
Histologically or cytologically confirmed diagnosis of esophageal squamous cell carcinoma (ESCC).
Locally advanced, unresectable esophageal cancer assessed by endoscopic ultrasound and imaging studies, including esophagography, contrast-enhanced CT scans of the lower neck, chest, and upper abdomen, MRI of the lower neck and chest, whole-body bone scintigraphy, or PET/CT; staged as T2-4, N0-3, M0-1 (M1 limited to supraclavicular lymph node metastasis).
Male or female patients aged 18 to 80 years.
No prior chemotherapy, radiotherapy, surgery, targeted therapy, or immunotherapy.
Participation in another clinical trial simultaneously, except for observational (non-interventional) studies.
Prior use of any targeted therapy.
Major surgery within 4 weeks prior to study entry (excluding vascular access procedures).
Uncontrolled comorbidities, including but not limited to active or ongoing infections, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina, arrhythmias, active peptic ulcer disease or gastritis, intestinal perforation, bowel obstruction, active bleeding disorders, or psychiatric/social conditions that may impair compliance with study requirements or the ability to provide informed consent.
