Robotic Gastrectomy for Locally Advanced Gastric Cancer After Neoadjuvant Therapy

Patients will undergo pre-operative drug treatment (any chemotherapy drug or immunotherapy drug are accepted).

"Eligible participants must have stage III resectable gastric or gastroesophageal junction (GEJ) adenocarcinoma based on imaging studies such as ultrasound endoscopy, CT, or MRI.~Patients will receive 3-4 cycles of neoadjuvant therapy, followed by imaging evaluations to assess the treatment response and determine eligibility for radical D2 gastrectomy. Within 2-6 weeks of the final neoadjuvant treatment cycle, eligible patients will undergo robotic radical gastrectomy."
