We analyzed the results of radiation therapy and evaluated its effectiveness as a treatment method. Between 1967 and 1980, a total of 200 patients with squamous cell carcinomas of the tongue (T2N0M0, stage II by UICC) were treated with interstitial brachytherapy alone or in combination with external irradiation (combined therapy) at the Department of Radiology, Osaka University Medical School.
We found that there was no significant difference between interstitial brachytherapy alone and combined therapy with regard to local control rates. With interstitial brachytherapy alone, local control rates for the Ir-192 remote afterloading method were greater than those for Ra-226 needles. The incidence of neck metastases out of the irradiated field was higher with combined therapy than with interstitial brachytherapy alone.
We found that irradiation treatment with thin Ir-192 wire using the afterloading method produced excellent results for patients with carcinomas of the tongue (T2N0 cases). Shika lgaku (J Osaka Odontol Soc) 1996 Sept; 59(3): 237-243.
