How to bladder cancer spread and metastasis

Bladder cancer, mainly in the following aspects of proliferation and metastasis of bladder cancer:
Bladder cancer spread and metastasis 1. Direct the local spread of invasive bladder cancer can be achieved through the following three mechanisms: block the spread of the most common, occurring in approximately 60% of the tumors, characterized by cancer cells directly below the primary mucosal lesions Forward invasion; tentacles like invasion: 25% occurred for the second common form of bladder cancer at the same time to the bladder wall cavity and infiltration; both sides of the extension: tumor cells in Bo under the membrane of normal appearance to the two side extension growth rate of about 10% of prostate involved up to 40%. Because the lack of muscular bladder diverticulum, bladder diverticulum bladder cancer invasion directly into the bladder from outside the organization. Standing of these tumors partial cystectomy, however, that the reserves have recently been less effective bladder surgery.
Proliferation and metastasis of bladder cancer 2. Metastasis of bladder cancer with metastatic spread of mainly two ways: that is spread through the lymphatic drainage system to the regional lymph node metastasis and hematogenous spread of distant metastasis. Bladder cancer cells can cross into the submucosa and lamina muscularis, submucosa and muscle layers in the tumor cells into the blood and lymph vessels and metastasis to local lymph nodes and (or) distant organs. Epithelium-derived lymphatic spread of bladder cancer was the primary means of transfer, regional lymph node recurrence of its main features, only occur late hematogenous distant metastasis. Pelvic lymph node metastasis in bladder cancer, the survival of patients with serious impact on the prognosis of pelvic lymph node dissection is still the prevention and treatment of lymph node means. Bladder cancer the most common sites of metastasis is the liver blood, spleen, bone, intestine, etc., have affected the possibility of any organ.
Proliferation and metastasis of bladder cancer 3. Planting bladder cancer can be planted into the abdomen through the incision, peeling of the urinary tract epithelium, removal of the prostate fossa, urethral injury and metastasis. Metastasis often occurs in poorly differentiated tumors.
