| Abstract | 「要旨」原発性肺癌53例において, 201Tl/67Ga粗摂取比(CUR)を求め, 実測生存期間(AST)および生存率との比較から, CURを予後因子として評価し得るか否か検討した. 死亡例32例において, CURとASTとの間には有意な正の相関が認められ(r=0.704, p<0.001), ことに腺癌においてはいっそう良好な正の相関が認められた(r=0.880, p<0.01). すなわち, CURが高い肺癌ほど, 実測生存期間が延長していた. 非手術例のstage III14例およびstage IV 23例の18か月生存率はそれぞれ19.4%, 13.8%であったのに対し, CUR<1.0群およびCUR≧1.0群での18か月生存率はそれぞれ6.0%, 50.0%であり, 非手術例においてはstageよりもCURによって, 予後の良好な群を選別し得ることが示唆された. 以上の結果より, 201Tl/67Ga粗摂取比を原発性肺癌における予後因子として評価し得ると結論された. |

| Abstract | Quantitative 201Tl and 67Ga scans were performed on 53 patients with primary lung cancer to measure 201Tl to 67Ga crude uptake ratio (CUR) by tumors. Based on the comparison of survival and actual survival time (AST) with CUR, we further evaluated whether or not CUR could predict the prognosis in lung cancer. A significant linear correlation was shown between CUR and AST (r=0.704, p<0.001) in 32 non-survivors, and AST was well correlated with CUR especially in adenocarcinomas (r=0.880, p<0.01). Namely, the higher the CUR, the longer was the AST. Also, the 18-month survivals in 14 inoperable patients with stage III and 23 with stage IV were 19.4 and 13.8 percent, respectively, whereas they were 6.0 and 50.0 percent in those with CUR less than 1.0 and more than 1.0. It was suggested, therefore, that CUR could more accurately classify the inoperable patients showing good prognosis when compared to clinical stages. From the results obtained, it was concluded that 201Tl to 67Ga crude uptake ratio (CUR) was a possible prognostic factor in primary lung cancer. |
