The Clinical Efficacy of Drug Sensitive Neoadjuvant Chemotherapy Based on Organoid Versus Traditional Neoadjuvant Chemotherapy in Advanced Gastric Cancer
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.

Outcome Measures
Primary Outcome Measures
- 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
- postoperative complication [an average of 1 year]
postoperative complication
- 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-year recurrence rate [an average of 3 year]
proportion of patients who relapse within 3 years after operation
- chemotherapy tolerance and adverse reaction rate [an average of 1 year]
- R0 resection rate [an average of 1 year]
