Using organoids to guide chemotherapy before bladder cancer surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants who are eligible for platinum-based neoadjuvant chemotherapy will have tumor tissue grown into organoids and undergo drug sensitivity testing to select a treatment plan. Those receiving organoid-guided plans are compared with patients receiving standard empirical neoadjuvant chemotherapy, with one-, three-, and five-year overall survival as primary outcomes. Survival differences are analyzed with Kaplan–Meier methods in a controlled, observational design. The protocol includes regular monitoring for treatment tolerance, adverse events, and follow-up after radical cystectomy.

Inclusion Criteria:

* 1\. Age 18-80 years, any gender; 2. Patients with cT2\~4aNxM0 MIBC who need neoadjuvant chemotherapy; 3. Patients who have not previously received systemic chemotherapy; 4. Patients who can tolerate platinum-based combination neoadjuvant chemotherapy; 5. ECOG performance status of 0-2; 6. According to the investigator's judgment, able to comply with the trial protocol, have good adherence, can cooperate in monitoring adverse events and efficacy, and participate in follow-up; 7. Voluntarily participate in this clinical trial, understand the study procedures, and have signed the informed consent form for participation.

Exclusion Criteria:

* 1\. Patients with muscle-invasive bladder cancer (MIBC) with clinical stage T4b or distant metastasis, or the patient's physical condition is assessed to be intolerable to radical cystectomy; 2. Immunodeficiency or damage (such as AIDS patients, patients on immunosuppressants or radiotherapy); 3. Study participants who are known to be allergic or allergic to study drugs, similar drugs, excipients; 4. Those who have been taking hormonal drugs for a long time or have a history of drug abuse and dependence; 5. Those who have recently planned to become pregnant or are already pregnant or breastfeeding; 6. Abnormal blood routine, liver and kidney function and coagulation indicators: (1 or more can be considered abnormal)

  1\) Neutrophil count (ANC) ≤1.5×109/L; 2) White blood cell count (WBC) ≤3.0×109/L; 3) Platelet count (PLT) ≤90×109/L; 4) Hemoglobin (HB) ≤90g/L; 5) Total bilirubin (TBIL) ≥1.5 × institutional upper limit of normal (ULN); 6) Estimated glomerular filtration rate (eGFR) ≤ 30 ml/min/1.73m²; 7) International normalized ratio (INR) and activated partial thromboplastin time (APTT) ≥ULN (except for patients receiving anticoagulant therapy, which need to be considered clinically acceptable by the investigator); 7. Study participants have other factors that could cause forced termination of this study, such as: 7) Patients have a previous or current diagnosis of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML); 8) Previous history of definite neurological or psychiatric disorders, including epilepsy or dementia; 9) Concomitant diseases that seriously endanger the safety of patients or affect the completion of the study (such as severe hypertension, diabetes, thyroid disease, etc.); 10) Other serious diseases require combined treatment, with serious laboratory abnormalities; 11) Other serious diseases accompanied by family or social factors that will affect the safety of research participants, or the collection of data and samples, etc.; 12) Have uncontrolled intercurrent illness, including but not limited to ongoing or active infection requiring treatment, symptomatic congestive heart failure, unstable angina pectoris, or arrhythmia; 8. Those who are not suitable to participate in this study in the opinion of the investigator.
