Local Hyperthermia with Interstitial Techniques1
The heating of deep visceral tumors with implanted electrodes and with self-regulating ferromagnetic thermoseeds was inves tigated. Clinical trials on six patients heated with implanted electrodes indicate that good local tumor control can be obtained by application of hyperthermia during a normal course of radio therapy. The heating method was found practical, and neither toxicity nor severe p...
متن کاملNew magnetic implant material for interstitial hyperthermia
Magnetic properties and heat generation characteristics of a bio-compatible ceramic Mg1þxFe222xTixO4 system have been investigated as an implant material for the magnetic induction hyperthermia. Curie temperature ðTcÞ of the ceramic decreases with increasing x; and become Tc , 350 K at x 1⁄4 0:35 and ,315 K at x 1⁄4 0:38; which is suitable Curie temperature for implant material. The temperature...
متن کاملTime-multiplexed two-channel capacitive radiofrequency hyperthermia with nanoparticle mediation.
BACKGROUND Capacitive radiofrequency (RF) hyperthermia suffers from excessive temperature rise near the electrodes and poorly localized heat transfer to the deep-seated tumor region even though it is known to have potential to cure ill-conditioned tumors. To better localize heat transfer to the deep-seated target region in which electrical conductivity is elevated by nanoparticle mediation, two...
متن کاملIntratumoral radiofrequency hyperthermia-enhanced direct chemotherapy of pancreatic cancer
PURPOSE To investigate the technical feasibility of using ultrasound-guided intratumoral radiofrequency hyperthermia (RFH) to enhance local chemotherapy of rat orthotopic pancreatic cancers. MATERIALS AND METHODS Orthotopic pancreatic cancer masses were established by inoculating luciferase/mCherry labeled-pancreatic cancer cells into the pancreatic tails of Lewis model rats via a laparotomy ...
متن کاملSingle radiofrequency source for MR and hyperthermia studies
Hyperthermia is an experimental/adjuvant therapeutic modality for cancer. Combining hyperthermia with the non-invasive metabolic studies using magnetic resonance (MR) is an interesting area of research and can provide useful information. In this paper, feasibility of using the same radio frequency source for carrying out combined hyperthermia and MR studies is demonstrated. A conventional RF hy...
