Conversion Therapy Plus Surgery and Radiotherapy for Retroperitoneal Nodal Metastases in Gastric Cancer
A Randomized, Controlled, Multicenter Phase II Study of Conversion Therapy Combined With Surgery and Radiotherapy for Retroperitoneal Lymph Node Metastases in Gastric Cancer
Source: ClinicalTrials.gov · Last updated 15 Oct 2026
Brief summary (registry, in English)
This is a randomized, controlled, multicenter phase II clinical trial evaluating the efficacy and safety of conversion therapy combined with radical gastrectomy and adjuvant radiotherapy targeting para-aortic (station 16) lymph nodes in patients with gastric adenocarcinoma and isolated station 16 nodal metastases. Eligible participants must have no evidence of peritoneal dissemination, visceral metastases, or non-regional lymphatic spread. Based on PD-L1 combined positive score (CPS), patients in the experimental arm will receive systemic therapy with SOX (S-1 plus oxaliplatin) with or without a PD-1 inhibitor, followed by D2 gastrectomy and postoperative adjuvant SOX chemotherapy, then intensity-modulated radiotherapy (IMRT) to the para-aortic region. The control arm will receive standard chemotherapy with CAPEOX or SOX, with or without immunotherapy, according to CPS status. The primary endpoint is progression-free survival (PFS), with secondary endpoints including overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety. This study aims to explore whether the addition of locoregional treatment to systemic therapy improves long-term outcomes in this select patient population.
