Metastatic bladder cancer is a dreaded disease characterized by the spread of cancer cells from the bladder to distant organs. Understanding the mechanisms by which bladder cancer metastasizes to specific sites is critical to developing effective therapeutics. At Alfa Cytology, we offer specialized mechanistic research services to study the complex process by which bladder cancer metastasizes to the lymph nodes, lungs, liver and bones.
Bladder cancer is the most common malignant tumor of the urinary tract. As the malignancy progresses, tumors located in the bladder epithelium metastasize to the urethral muscles and, more likely, to the lymph nodes or other organs. Of these, lymph node (LN) metastases accounted for the majority. Understanding the underlying mechanisms of metastasis is essential for developing effective treatment strategies against metastatic bladder cancer and improving prognosis.

Metastasis Mechanism | Description |
---|---|
Epithelial-Mesenchymal Transition (EMT) | EMT is driven by signaling pathways such as TGF-β, Wnt/β-catenin and Notch, resulting in epithelial cells losing intercellular adhesion and acquiring a mesenchymal phenotype that allows them to migrate and invade surrounding tissues. |
Angiogenesis | Formation of new blood vessels crucial for tumor growth and metastasis. VEGF and its receptors play a key role in bladder cancer angiogenesis. Increased expression of VEGF and pro-angiogenic factors promotes blood vessel formation, supporting tumor growth and facilitating the spread of cancer cells to distant organs. |
Extracellular Matrix (ECM) Remodeling | Bladder cancer cells secrete enzymes including MMPs, particularly MMP-2 and MMP-9, which degrade the ECM, thereby allowing the cancer cells to invade surrounding tissues and spread in the bloodstream or lymphatics, contributing to the formation of metastatic lesions. |
Immune Evasion | Bladder cancer cells use a variety of mechanisms to evade immune surveillance and promote metastasis. For example, they create an immunosuppressive microenvironment by down-regulating MHC molecules and secreting immunosuppressive factors, which promotes the survival and spread of metastatic bladder cancer cells. |
Circulating Tumor Cells (CTCs) and Dormancy | Disseminated tumor cells can enter the bloodstream and form micrometastases. However, not all cells establish metastatic lesions. Disseminated tumor cells can enter the bloodstream and form micro metastases. The mechanisms underlying dormancy and reactivation involve interactions with the metastatic microenvironment, including angiogenic switch, immune system modulation, and interactions with stromal cells. |
