[Clinical effects of hyperthermia treatment for recurrent bladder cancer]

The usefulness of the application of thermotherapy for cases of recurrent bladder cancer was investigated. We encountered 7 cases of which intravesical recurrent bladder cancer was found to occur in 5 cases. The involvement of the lymph node was found in one case and recurrence in intrapelvic cavity was observed in another case after total cystectomy. As a treatment method, thermotherapy was applied for the above 5 cases between 2 and 7 times in conjunction with an intrabladder injection of hydroxy propyl cellulose-adriamycin following M-VAC treatment for one case; the combined use of OK 432 and 5Fu was administered for another case together with thermotherapy applied 4 to 5 times, respectively. Results; Three of the above 5 cases were found to be CR including 2 cases of PR. One case was MR with another case of NC. Shrinkage of the tumor by more than 50% was recognized in one case of NC after five months.
