A CASE OF AGGRESSIVELY GROWING BLADDER CANCER IN PATIENT WITH LONG TERM CYSTOSTOMY DUE TO SPINAL CORD INJURY

The patient was a 38-year-old man. A cystostomy catheter had been inserted when he was 23 years of age for neuropathic bladder due to cervical spinal cord injury at 20 years of age. Purulent discharge from around the cystotomy had continued for approximately 4 months. Examination revealed the formation of a subcutaneous tumor around the cystostomy, with elevated carcinoembryonic antigen (CEA) levels (459.4 ng/ml) in the blood. Urothelial carcinoma was detected using open biopsy. It was considered that primary urothelial carcinoma of the bladder had progressed along the cystostomy, and clinical stage 4 cT4N2M0 was diagnosed, with intrapelvic lymph node metastasis evident on imaging. Four courses of gemcitabine-cisplatin chemotherapy were administered; a partial response was obtained, after which cystectomy and ileal conduit formation were performed with the main aim of improving difficulty in urination. However, retroperitoneal lymph node and liver metastases were observed 1 month postoperation with rapid enlargement; the patient died approximately 2 months after the surgery. The CEA level was observed to be 18,998 ng/ml before he died. Here, we have reported this case with a discussion of the literature concerning the association between long-term indwelling catheter in patients with spinal cord injury and the development of bladder cancer.
