-Summary

The study is a real-world observational clinical study. Patients diagnosed as gastric cancer through histopathology were screened and enrolled. Before anti-tumor treatment, gastroscopy biopsy tissue specimens, surgical specimens, and malignant pleural effusion or ascites specimens, etc. are collected. The investigators will perform a drug sensitivity testing based on a novel drug susceptibility testing method to test the commonly used anti-tumor treatment regimens. Patients were given conventional anti-tumor treatment according to the medical judgment of the doctors. Finally, the investigator will evaluate the consistency of clinical efficacy in gastric cancer treatment and drug susceptibility outcomes.

+Outcome measures

Primary outcomes

Disease-free survival [From date of surgery until the date of first documented recurrence，up to 3 years]: An Indicator of efficacy of postoperative adjuvant therapy
Sensitivity [Through study completion, an average of 1 year]: Cases in which drug susceptibility results are sensitive to the antineoplastic regimen as a percentage of the cases that are effective in clinical evaluation
Specificity [Through study completion, an average of 1 year]: Cases in which drug susceptibility results are resistance to the antineoplastic regimen as a percentage of the cases that are ineffective in clinical evaluation
