Successful treatment of recurrent kidney pelvic squamous cell cancer with chemotherapy and radiotherapy: a case report]

We report a case of recurrent squamous cell carcinoma of the renal pelvis. A 61-year-old woman was readmitted to our hospital 4 months after left nephrectomy. The medical imaging method revealed a left retroperitoneal tumor and squamous cell carcinoma related antigen (SCC-Ag) elevated (82 ng/ml). We suspected a recurrent tumor from renal pelvic cancer. She received 2 courses of systemic chemotherapy with 5-FU and CDDP, but the tumor did not change. As a second treatment, combined radiotherapy with PEP was given. The tumor was reduced and SCC-Ag returned to the normal level. The patient is alive with no recurrence or metastasis at one year following these therapies.
