Squamous cell carcinoma of bladder.

Examination of the histology of all bladder tumors presented to the London Hospital over a ten-year period revealed a surprisingly low incidence of squamous bladder carcinoma. We would support the view of other workers that this tumor usually presents at an advanced stage and carries with it a poor prognosis. However, when no evidence of metastatic disease is evident, treatment with standard protocol of radiation therapy and cystectomy should achieve the same results as for the transitional cell tumor. Squamous cell carcinoma of the bladder would appear to be as radiosensitive as its transitional cell counterpart.
