Study Details

Study Description

Brief Summary

Neoadjuvant chemotherapy has become the mainstream recommended treatment for advanced gastric cancer. However, due to the heterogeneity of gastric cancer, part of some patients fail to benefit from the treatment. This project aims to compare the clinical efficacy of individualized neoadjuvant therapy based on patient-derived organoid drug sensitivity assay and traditional regimen, exploring the advantages and disadvantages of these two treatments. And access the safety and clinical value of the personalized neoadjuvant therapy based on patient-derived organoid drug sensitivity assay in advanced gastric cancer.

Arms and Interventions

Arm Intervention/Treatment
PDO group

Patients with stage III gastric cancer who need neoadjuvant chemotherapy before radical surgery are recruited. And they are treated with individualized neoadjuvant therapy under the guidance of a patient-derived organoid (PDO)-based drug sensitivity assay.

Outcome Measures

Primary Outcome Measures

  1. Objective Response Rate [an average of 1 year]

    proportion of patients whose tumor volume reduced to a predetermined value and maintain the minimum time limit.

Secondary Outcome Measures

  1. postoperative complication [an average of 1 year]

    postoperative complication

  2. postoperative tumor regression grading [an average of 1 year]

    grade the pathological response of tumor after neoadjuvant treatment, which is usually classified according to the proportion of fibrosis and residual tumor in tumor tissues.

  3. 3-year recurrence rate [an average of 3 year]

    proportion of patients who relapse within 3 years after operation

  4. chemotherapy tolerance and adverse reaction rate [an average of 1 year]

  5. R0 resection rate [an average of 1 year]
