| Abstract | 「緒言」癌の診断および治療にRIの腫瘍内沈着を利用できる可能性があるかどうかを, 肺癌についてまず試みたので報告する. 「方法」肺癌の患者に, 選択的気管支動脈撮影を施行し, 次いでそのカテーテルを通じて, 131I・MAA250μcを注入する. 注入直後および経時的平面スキャニングおよび線スキャニングを行なう. 腫瘍スキャニングが, X線写真上の腫瘍と合致するか否かを確かめるために, 両側乳頭および胸骨突起の先端に鉛のマークをつけて, 管球フィルム間距離を2mにて胸部正側のX線撮影を行なう. かくしてえられたX線写真は拡大率が1.1倍であるので, 1.0倍に縮小してスキャニング上の3点を合わせて重ねる. 「結果」症例はTable1に示すごとく5例である. 症例1は42才の女で, 右上肺野に直径5cmの円形陰影があり, 肺尖部には数個の転移像がみられる. 胸壁に近い転移腫瘍の穿刺による細胞診により腺癌と判明した. |

| Abstract | Selective bronchial arteriography was performed by Seldinger's method using Odman's red catheter for five patients of pulmonary cancer. Tortuous arteries and tumor stains were recognized in the main tumor, metastatic tumor and regional lymph node swelling of the lung. Following immediate after the arteriography, 250μc of 131I-MAA was injected into bronchial artery through the catheter. The distribution of 131I-MAA covered the capillary bed of bronchial artery by area and linear scanning. The coverage of 131I-MAA was proved by superimposition with the chest roentgenograms. As time relapsed, the distribution of 131I-MAA became dominant in the tumor site as 131I-MAA was decreased in the surrounding tissue. Finally, the positive tumor scintigrams were obtained in both PA and lateral projections. That is, as far as 131I-MAA was injected into the capillary bed of the tumor, the tumor was positively scanned in a few days after the injection, and this phenomenon continued several days. In all 5 cases, main tumor, metastatic tumor and regional lymph node swelling were positively scanned in all or at least in part. |
