Brief Summary

To investigate effect of intravesical mitomycin-C(MMC) applied with bladder wall thermotherapy system on reccurrence and progression status of intermediate and high risk non muscle invasive bladder cancer

Detailed Description

Before the application of TCT, complete transurethral bladder tumour resection (TURBT) was performed. RE-TURBT was conducted within 4 weeks for patients with initial T1 pathology. The first TCT instillation was applied at 1mo following the TURBT or the RE-TURBT.

Thermochemotherapy application and treatment schedule:

The bladder wall TCT (BWT) system (Elmedical Ltd, Hod-Hasharon, Israel) was used as a conductive heating modality. MMC (40 mg; MMC Kyowa Hakko Kogyo Co., Ltd., Tokyo, Japan) was mixed with 50 mL of 0.9% saline solution and applied using a disposable silicone 20Fr 3-way TCT catheter (UniThermia catheter; Elmedical Ltd). In each session, the bladder was irrigated with MMC solution at 42°C-45°C for 45 min via the BWT system. The treatment schedule consisted of an initial 6-week instillation, followed by control cystoscopy and urine cytology in the 3rd month and monthly instillations up to 1 yr. Urine cytology and cystoscopy were performed every three months. The samples were collected from the suspected areas during cystoscopy. At the end of the first year, control cystoscopy with random bladder biopsies was conducted. During the second year, routine controls were conducted every three months. Subsequently, follow-ups were performed every six months. In case of development of any complication in a patient, TCT was discontinued. Before each instillation of TCT, clear urine cultures were obtained from all patients. No prophylactic anticholinergic was administered prior to intravesical TCT. If TUR BT pathology was Ta or T1 during the follow-up, it was accepted as a recurrence. If it was CIS or T2, it was accepted as a progression. All adverse events observed during the study were recorded according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0 [9. All study protocols were approved by the local ethical committee at our institution. An informed consent was obtained from all patients.
