Cross-sectional 

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.

纳入标准:

(1)年龄在 50-70 岁之间,性别不限; (2)经病理组织学或细胞学确诊为局部晚期或转移性尿路上皮癌; (3)不适合接受顺铂为基础的化疗; (4)接受 RC48 联合特瑞普利单抗一线治疗; (5)治疗前基线组织(FFPE)样本完整,可用于 RNAseq 测序分析; (6)完整临床病理数据齐全,包括 RECIST 1.1 疗效评估结果、无进展生存期(PFS)、总生存期(OS)、HER2 IHC 状态(IHC 2+/3+)以及 PD-L1 CPS 评分。

Inclusion criteria

(1) Aged between 50-70 years old, no gender limit; (2) Locally advanced or metastatic urothelial carcinoma confirmed by histopathology or cytology; (3) Not suitable for receiving cisplatin-based chemotherapy; (4) Receive first-line treatment with RC48 combined with toripalimab; (5) The pre-treatment baseline tissue (FFPE) sample is complete and can be used for RNAseq sequencing analysis; (6) Complete clinicopathological data, including RECIST 1.1 efficacy evaluation results, progression-free survival (PFS), overall survival (OS), HER2 IHC status (IHC 2+/3+) and PD-L1 CPS score.

排除标准:

(1)年龄低于 50 岁或高于 70 岁; (2)病理诊断非尿路上皮癌,或为早期尿路上皮癌可通过手术根治,无需一线接受 RC48 联合特瑞普利单抗治疗; (3)适合顺铂为基础的化疗方案; (4)未接受 RC48 联合特瑞普利单抗一线治疗; (5)治疗前基线组织(FFPE)样本缺失或不完整,无法进行 RNAseq 测序分析; (6)临床病理数据缺失,无法完成 RECIST 1.1 疗效评估、PFS/OS 统计、HER2 IHC 状态或 PD-L1 CPS 评分判定。

Exclusion criteria:

(1) Age below 50 years or above 70 years old; (2) Pathologically diagnosed non-urothelial cancer, or early-stage urothelial cancer, can be cured radically through surgery and does not require first-line treatment with RC48 combined with toripalimab; (3) Suitable for cisplatin-based chemotherapy regimen; (4) Not receiving first-line treatment with RC48 combined with toripalimab; (5) The baseline tissue (FFPE) sample before treatment is missing or incomplete, and RNAseq sequencing analysis cannot be performed; (6) Clinicopathological data are missing, and RECIST 1.1 efficacy evaluation, PFS/OS statistics, HER2 IHC status or PD-L1 CPS score determination cannot be completed.
