We studied on the incidence of vascular invasion of bladder cancer and the relation between the vascular invasion and distant metastasis.
Histologic materials were obtained from twenty-six (26) patients with transitional cell carcinoma of the bladder treated by partial and total cystectomy during the 3 year period from November 1976 to October, 1979.
The blood vessel and lymphatics invasions were observed in 13 cases (50.00) and 35% in the casas at the low atage (stage O, A, B1) compared to 100% in the cases at the high stage (stage B2, C)
There were a 33.3% vascular invasion in the cases of grade III and a 76.9% in the cases of grade IV.
Vascular invasion was revealed at a higher frequency with tumors of high stage and high grade. Metastases were occurred only in one (7.7%) of 13 without vascular invasion.
The relationahip between distant metastasis and vascular invasion isquite apparent in this study and this relationship is very important in planning subsequent therapy.
