研究目的: |
深入分析肿瘤微环境(TME)与癌细胞内在程序的协同作用,揭示 RC48 联合 PDL1(特瑞普利单抗)治疗 HER2 高表达局部晚期或转移性尿路上皮癌的耐药潜在机制,预测耐药患者的潜在治疗靶点,为临床诊疗提供依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
1.In-depth analysis of the synergy between the tumor microenvironment (TME) and the intrinsic programs of cancer cells. 2.Revealing the potential mechanism of drug resistance of RC48 combined with PDL1 (toripalimab) in the treatment of locally advanced or metastatic urothelial carcinoma with high HER2 expression. 3.Predicting potential therapeutic targets for drug-resistant patients. 4.Provide basis for clinical diagnosis and treatment. |
