Pancoast tumour treated with combined radiotherapy and hyperthermia — a preliminary study

Abstract

Six patients with Pancoast (superior sulcus) tumours were treated with combined radiotherapy and hyperthermia from April 1986 to December 1989. Radiotherapy was performed using 10 MV X-ray, and all patients received total doses of 60–74 Gy, in five fractions per week, during 5.5–15 weeks. Hyperthermia was performed once or twice a week within 30 min after each irradiation, using 8 MHz RF capacitive heating equipment (Thermotron RF-8). Partial response, defined as 50% or more regression of the tumour, was observed in four of the six patients. Three patients are alive 30, 28, and 14 months after their treatments. Radiotherapy combined with hyperthermia appears to be a promising and effective means for treating Pancoast tumours.
