Methods: This retrospective, multicenter, real-world study included patients with locally advanced or metastatic UC who received RC48 in five hospitals in China between July 2021 and April 2022.

Bladder paraganglioma: basic characteristics and new perspectives on perioperative management.

Purpose: Paraganglioma and pheochromocytoma are rare neuroendocrine tumors with severe metabolic and cardiovascular complications. Bladder PGLs are rare, and their clinical management is not precise. Here, we discuss the basic characteristics and perioperative management of bladder PGLs.

RAB20 Promotes Proliferation via G2/M Phase through the Chk1/cdc25c/cdc2-cyclinB1 Pathway in Penile Squamous Cell Carcinoma.

RAB20, a member of the RAS GTPase oncogene family, is overexpressed in several cancers with poor outcomes, promoting tumorigenesis and inducing genomic instability. Here, we performed comprehensive genomic sequencing on eight penile squamous cell carcinoma (PSCC) and normal tissue pairs and found that RAB20 was upregulated in tumors, especially in metastatic lymph nodes. RAB20 overexpression in tumors was further verified by qPCR, Western blotting, and immunohistochemistry of our newly established PSCC cell lines and paired tissues.
