Details and patient eligibility

About

This project plans to establish an organoid chip model of prostate cancer patients with internal organ metastasis from surgical or biopsy tissue sources, and test the sensitivity of commonly used chemotherapy drugs based on organoid chip drug sensitivity testing technology to screen out sensitive individualized treatment plans.

Full description

This project plans to establish an organoid chip model of prostate cancer patients with internal organ metastasis from surgical or biopsy tissue sources, and test the sensitivity of commonly used chemotherapy drugs based on organoid chip drug sensitivity testing technology to screen out sensitive individualized treatment plans;The final medication regimen for patients is determined by doctors based on their experience and in vitro drug sensitivity results. The actual clinical efficacy of medication is tracked for patients, and the organoid chip drug sensitivity detection model is analyzed as a predictor of the sensitivity, specificity, and accuracy of anti-tumor chemotherapy drugs, providing data reference for clinical applications.At the same time, analyze the accuracy of drug sensitivity testing results and clinical empirical medication.If patients are treated with a chemotherapy combined with immunotherapy regimen, the in vitro sensitivity of immune drugs will be determined using organoid-immune co-culture technology, and exploratory research on the predictive performance of immune models will be conducted in conjunction with clinical medication.
