Evaluating the Efficacy of Neoadjuvant Chemotherapy Drugs Based on Organoid Technology

Summary

This study, through a clinical controlled trial, compared the one-year, three-year, and five-year overall survival rates between patients receiving a treatment plan guided by organoid drug sensitivity and those receiving conventional empirical treatment. Univariate Kaplan-Meier survival analysis was used to compare the differences in overall survival between the two groups. The study aimed to evaluate the application value of tumor organoid drug sensitivity testing in guiding neoadjuvant chemotherapy for bladder cancer.

Eligibility

Inclusion Criteria:
