Spindle and giant cell carcinoma of the bladder. Report of 3 cases.

3 cases of spindle and giant cell carcinoma are reported. 2 patients with T3N0M0 and T3N1M0 tumors underwent radical cystectomy. They died 8 and 9 months after cystectomy for local recurrence and tumor metastases. Neither radiotherapy nor chemotherapy were effective in these 2 patients. 1 patient with T1NXM0 disease underwent resection of the tumor through cystotomy. Although she had neither adjuvant chemotherapy nor radiotherapy, she is well without recurrence 6 years after surgery. Early surgical resection of the tumor may be the only currently accepted therapy of spindle and giant cell carcinoma of the bladder.
