Local hyperthermia with interstitial techniques

Academic Article

Abstract

  • The heating of deep visceral tumors with implanted electrodes and with self-regulating ferromagnetic thermoseeds was investigated. 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 radiotherapy. The heating method was found practical, and neither toxicity nor severe patient discomfort was encountered. However, temperature inhomogeneity within the tumor volume remains a problem. Theoretical studies and an animal experiment indicate that temperature homogeneity can be largely improved by heating the tumor with thermoseeds made of an alloy of 70.4% nickel and 29.6% copper. The highly temperature-dependent rate of heat production in the vicinity of the Curie point, about 50° for this material, provides automatic temperature regulation.
