[A case of squamous cell carcinoma of the urinary bladder effectively responsive to combination chemotherapy].

A case of invasive pure squamous cell carcinoma of the urinary bladder effectively responsive to combination chemotherapy in a 79-year-old female is reported. Clinical staging of the tumor was T3b. We used combination chemotherapy with methotrexate, peplomycin and cis-platinum (MBD regimen) before radical cystectomy. Remarkable regression of the tumor was identified by computed tomographic scan after one course of chemotherapy and the surgical specimen revealed no viable tumors. The patient has been very active in her daily life without evidence of local recurrence or metastasis for more than one year. Squamous cell carcinoma of the bladder generally is regarded as having a poor prognosis with 5-year survival rates ranging from 7.4 to 26% and effective chemotherapy has not yet been established. Our experience suggests that the cure rate of pure squamous cell carcinoma may be improved markedly by the use of MBD regimen.
