A Clinical Study Aims to Assess the Consistency of Clinical Efficacy in Gastric Cancer Treatment and Drug Susceptibility Outcomes Using a Novel Drug Susceptibility Testing Method

Recruiting

• Conditions: Gastric Cancer; Organoids

• Registration Number: NCT06100003
• Lead Sponsor: Funan Liu

Brief 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.
