简要总结
This is a phase II study to determine the safety and efficacy of tislelizumab when given in combination with nab-paclitaxel as treatment for patients with high-risk non-muscle-invasive bladder cancer (HR NMIBC) which is not completely resectable. Patients will receive treatment with tislelizumab in combination with nab-paclitaxel every 3 weeks for 4 treatment cycles over 12 weeks followed by transurethral resection biopsy.

- •a. T1 b. High-grade Ta c.Carcinoma in situ(CIS);
- •Multi-point biopsy of bladder shows there are more than 2 section and over 3 points of pathological specimens are diagnosed as above, meanwhile, the tumor has to be diagnosed as not completely resectable by at least 2 senior urologist;
- •Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-2;
- •Agreed to provide tissue examination samples (for detection of PD-L1 expression, tumor mutation load, IHC, detection of DNA and RNA, etc;)
- •Organ function level must meet the following requirements:
- •Hematological indexes: neutrophil count >= 1.5x10^9/L, platelet count >= 80x10^9/L, hemoglobin >= 6.0 g/dl (can be maintained by blood transfusion);
