Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We plan to evaluate the efficacy and safety of proximal gastric vs. total gastric radical resection after SOX combined with anti-PD-1 neoadjuvant therapy in locally advanced upper gastric cancer

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Gastric cancer is one of the most common malignant tumors in China, and its morbidity and mortality rank among the top three for a long time.How to improve the survival rate of patients with advanced gastric cancer is the key to improve the prognosis.At present, neoadjuvant chemotherapy combined with immunosuppressants has a higher pathologic complete response (pCR) rate, reduce the clinical stage of tumors and improve the resection rate of radical surgery.Some studies have suggested that preserving partial gastric lymph nodes may enhance immunotherapy efficacy.Proximal radical gastrectomy versus total radical gastrectomy can reduce the scope of surgical resection and preserve some lymph nodes, which may contribute to long-term survival and improve postoperative quality of life of patients. It is expected to translate the short-term benefit of neoadjuvant immunotherapy into the benefit of patient overall survival (OS) rate.At the same time, our previous studies have shown that the methylation level of PD-L1 K162 can be used as a new indicator to predict the sensitivity of anti-PD -(L)1 immunotherapy, which is expected to be further confirmed in this clinical trial.Therefore, we plan to conduct a comparative study on the effectiveness and safety of proximal gastric vs. total gastric radical resection after SOX combined with anti-PD-1 neoadjuvant therapy for locally advanced upper gastric cancer, which is expected to propose new changes in surgical methods for gastric cancer and a new indicator for screening the advantages of gastric cancer immunotherapy in the era of immunotherapy.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Proximal radical gastrectomy group

Patients with locally advanced upper gastric cancer were enrolled for 4 cycles of SOX combined with anti-PD-1 neoadjuvant therapy. After the completion of neoadjuvant therapy, the efficacy was evaluated, and the patients were divided into two groups according to the remission of lesions: (1) PD (Progressive disease) and SD (Stable disease) patients were replaced with conservative treatment or surgical treatment after MDT (Multi-disciplinary Treatment) discussion; (2) For PR (Partial response) and CCR (Clinical complete response) patients, if the patients met the criteria for proximal gastric radical surgery, the enrolled patients were randomly divided into 2 cohorts, which were divided into experimental group : the group of proximal gastric radical surgery; Four cycles of SOX combined with anti-PD-1 adjuvant therapy continued after surgery, and anti-PD-1 adjuvant therapy lasted for 1 year.

Group Type EXPERIMENTAL

Proximal radical gastrectomy

Intervention Type PROCEDURE

Proximal radical gastrectomy : Dissection of lymph nodes No.1,2,3a,4sa,4sb,7,8a, 9, 11p, 11dare recommended. The tumor involved more than 3cm of esophagus and additional dissection No.19, 20, 110. Gastrointestinal reconstruction method: double channel anastomosis is recommended, and other anastomosis methods can be carried out according to the surgeon\'s habit.

Total radical gastrectomy group

Patients with untreated, operable locally advanced upper gastric cancer who signed informed consent and met the screening criteria were enrolled for 4 cycles of SOX combined with anti-PD-1 neoadjuvant therapy. After the completion of neoadjuvant therapy, the efficacy was evaluated, and the patients were divided into two groups according to the remission of lesions: (1) PD and SD patients were replaced with conservative treatment or surgical treatment after MDT discussion; (2) For PR and CCR patients, if the patients met the criteria for proximal gastric radical surgery, the enrolled patients were randomly divided into 2 cohorts, Cohort 2 (control group) : total radical gastrectomy group. Four cycles of SOX combined with anti-PD-1 adjuvant therapy continued after surgery, and anti-PD-1 adjuvant therapy lasted for 1 year.

Group Type ACTIVE_COMPARATOR

Total radical gastrectomy

Intervention Type PROCEDURE

total radical gastrectomy : Dissection of lymph nodes No.1-7, 8a, 9, 11p, 11d, 12a are recommended. The tumor involved more than 3cm of esophagus and additional dissection No.19, 20, 110. Gastrointestinal reconstruction method: Roux⁃en⁃Y anastomosis is recommended
