Hyperthermia, Radiation And Chemotherapy: The Role Of Heat In Multidisciplinary Cancer Care., Mark Hurwitz, Md, Paul R. Stauffer
Department of Radiation Oncology Faculty Papers
The compelling biologic basis for combining hyperthermia with modern cancer therapies including radiation and chemotherapy was first appreciated nearly half a century ago. Hyperthermia complements radiation as conditions contributing to radio-resistance generally enhance sensitivity to heat and sensitizing effects occur through increased perfusion/tumor oxygenation and alteration of cellular death pathways. Chemosensitization with hyperthermia is dependent on the particular mechanism of effect for each agent with synergistic effects noted for several commonly used agents. Clinically, randomized trials have demonstrated benefit including survival with the addition of hyperthermia to radiation or chemotherapy in treatment of a wide range of malignancies. Improvements in …

Thermal Dosimetry Characteristics Of Deep Regional Heating Of Non-Muscle Invasive Bladder Cancer., Titania Juang, Paul R. Stauffer, Oana A Craciunescu, Paolo F Maccarini, Yu Yuan, Shiva K Das, Mark W Dewhirst, Brant A Inman, Zeljko Vujaskovic
Department of Radiation Oncology Faculty Papers
PURPOSE: The aim of this paper is to report thermal dosimetry characteristics of external deep regional pelvic hyperthermia combined with intravesical mitomycin C (MMC) for treating bladder cancer following transurethral resection of bladder tumour, and to use thermal data to evaluate reliability of delivering the prescribed hyperthermia dose to bladder tissue.
MATERIALS AND METHODS: A total of 14 patients were treated with MMC and deep regional hyperthermia (BSD-2000, Sigma Ellipse or Sigma 60). The hyperthermia objective was 42° ± 2 °C to bladder tissue for ≥40 min per treatment. Temperatures were monitored with thermistor probes and recorded values were used …
A Pilot Clinical Trial Of Intravesical Mitomycin-C And External Deep Pelvic Hyperthermia For Non-Muscle-Invasive Bladder Cancer., Brant A Inman, Paul R. Stauffer, Oana A Craciunescu, Paolo F Maccarini, Mark W Dewhirst, Zeljko Vujaskovic
A Pilot Clinical Trial Of Intravesical Mitomycin-C And External Deep Pelvic Hyperthermia For Non-Muscle-Invasive Bladder Cancer., Brant A Inman, Paul R. Stauffer, Oana A Craciunescu, Paolo F Maccarini, Mark W Dewhirst, Zeljko Vujaskovic
Department of Radiation Oncology Faculty Papers
PURPOSE: This paper aims to evaluate the safety and heating efficiency of external deep pelvic hyperthermia combined with intravesical mitomycin C (MMC) as a novel therapy for non-muscle-invasive bladder cancer (NMIBC).
MATERIALS AND METHODS: We enrolled subjects with bacillus Calmette-Guérin (BCG) refractory NMIBC to an early phase clinical trial of external deep pelvic hyperthermia (using a BSD-2000 device) combined with MMC. Bladders were heated to 42 °C for 1 h during intravesical MMC treatment. Treatments were given weekly for 6 weeks, then monthly for 4 months. Heating parameters, treatment toxicity, and clinical outcomes were systematically measured.
RESULTS: Fifteen patients were …
