舌癌の「セシウム」針Cs137療法

　1．緒言

　近年，放射線療法が非常に盛になり，「レントゲン」「ラジウム」の他に，「コバルト」「セシウム」等種々の物質が用いられるようになつた。「セシウム」に就いても，既に柏戸教授，浅井氏の喉頭癌に対する放射線療法中に，その使用効果が報告されているが，此の度横浜医大放射線科の御厚意により，舌癌の治療に「セシウム］針を使用する機会を得たので，此所に其の治療法と感想の一端を報告し諸賢の御参考に供する次第である。

Homma reports that, in a recurring epi- thelioma of the tongue that followed initial surgical treatment, the use of Cs¹³⁷ by needle implantation proved to be effective in allaying further progress of that malignancy even after the period of 9 months since this treatment had been started. Epithelio-ma of the tongue was found in a woman aged 29. Each needle holding Cs¹³⁷ is about 3 cm in length capable of emitting 2 cm of radiation equivalent to 1 mg radium needle. In the present case 7 such needles were inserted into the malignancy for the period of 8 days is such a way that these occupied the area surrounding the involvement close to the normal areas beyond and placed a little less than 1 cm apart. In order to accertain equal distribution of needle im-plantation in the involvement the procedure is examined by streoscopic X-ray for veri-fications. It is also important that use of antibiotics should not be omitted in this treatment to avoid secondary infection of the tissues that may be destroyed by the process.
