Abstract

Recurrent and/or inoperable gastric cancer has been treated by thermoradiotherapy at Kyoto University Hospital since 1983. In the present study, the efficacy of hyperthermia (using radiofrequency capacitive heating) plus radiotherapy for gastric cancer was evaluated in 21 patients with local recurrence, abdominal wall metastases, peritonitis carcinomatosis or paraaortic node metastases. The intratumour temperature was measured using a microthermocouple thermometer. The means of the maximum, average, and minimum intratumour temperature were 43·5, 42·1, and 41·1°C respectively. The local tumour response was evaluated using computed tomography (CT). The local response rate (complete regression plus partial regression/all tumours) was 88·9%, which seemed to be higher than that of other reports using thermochemotherapy or radiotherapy alone. The one-year cumulative survival rate was 39·1%.
