Mitomycin C With Hyperthermia and Intravesical Mitomycin C to Treat Recurrent Bladder Cancer
Hypothesis: In selected patients external hyperthermia will be used in combination with intravesical Mitomycin-C (MMC) to treat recurrent transitional cell carcinoma (TCC) of the bladder after local resection and standard adjuvant therapy and thus prevent or delay recurrence and the need for radical cystectomy.

Experimental: Hyperthermia system, Mitomycin C
Pilot study single arm study to test the safety, tolerability and clinical benefit of regional hyperthermia and mitomycin-C intravesical chemotherapy to treat non-invasive Transitional Cell carcinoma (TCC) of the bladder that has recurred after standard resection and adjuvant therapy.
Device: Hyperthermia System
Hyperthermia applied to heat the bladder to a temperature of 42 degrees Celsius for 40-60 minutes concurrent with mitomycin Treatment Schedule: 6 Weekly Sessions (Induction) followed by 4 Monthly Sessions (Maintenance) until documented second recurrence
Other Name: BSD 2000 Hyperthermia systemDrug: Mitomycin C
40 mg in 40 ml sterile water instilled into bladder
Other Name: Mutamycin
It is well established that tumor cells are sensitive to heat and when combined with a chemotherapeutic agent, drug uptake and intracellular distribution of drug within malignant cells is improved due to increased cellular permeability. Further, hyperthermia inhibits deoxyribonucleic acid (DNA) repair as a result of increased reaction between DNA and chemotherapy. By heating bladder tissue and accelerating the necessary series of reactions to link agents such as mitomycin C to cell DNA, this effect may be optimized. Depending on the extent of resection (and location, size, and depth of invasion of remaining tumor) after transurethral resection of the bladder tumor(TURBT), recommended adjuvant therapy consists of intravesical chemotherapy. MMC has been studied at doses as high as 80 mg without producing significant or irreversible side effects. The most commonly used dose of mitomycin is 40 mg.2
This pilot study proposes to use Mitomycin C at a dose of 40 mg in conjunction with deep hyperthermia to enhance the effect intravesical chemotherapy as second-line treatment of recurrent TCC (Stage Ta, T1, or Tis) of the bladder after surgical resection and standard adjuvant therapy.
