Squamous carcinoma of the bladder: treatment by radical cystectomy.

Analysis of records of microscopic slides from 33 patients with pure squamous carcinoma of the bladder who underwent radical cystectomy and lymphadenectomy disclosed a 5-year survival rate of 48 per cent. This survival rate correlated closely with pathologic stage and histologic grade of tumor and was significantly better than for each corresponding stage of transitional cell carcinoma of the bladder. The favorable survival rate and reasonably low operative mortality rate support aggressive therapy of this uncommon lesion.
