| Abstract | 「要旨」原発性肺癌におけるガリウムシンチグラフィの肺門部リンパ部転移の検出能を評価する目的で, 転移の有無が明らかな117例234肺門を対象に肺門部集積所見を分類・検討した. 肺門部集積所見は全面像, 後面像それぞれを集積なし(grade 0), 椎体と同程度の集積(grade 1), 椎体より高い集積(grade 2)の3種類に分類し, gradeの前面像, 後面像の合計が3以上の場合を陽性とした. 肺門リンパ節転移を認めた44例49肺門では, 集積陽性は10例11肺門, 肺門リンパ節転移を認めなかった73例146肺門では, 集積陽性は6例10肺門であった. 症例別および肺門別の感度はそれぞれ22%, 23%, 特異性は91%, 93%であった. 片側集積陽性群に比較すると, 両側集積陽性群は肺門リンパ節転移評価の正診率が有意に劣った. 原発集積や組織型と肺門部リンパ節転移巣集積との明らかな関連は認められなかった. 以上の結果から, 肺門リンパ節転移評価におけるガリウムシンチグラフィの有用性には明らかな限界があることが示唆された. |

| Abstract | We evaluated hilar uptake on 67Ga-citrate scintigraphy and correlated with hilar lymph node metastases in one-hundred seventeen cases (two-hundred thirty four hila) of bronchogenic carcinoma. Hilar uptake was classified into three grades independently on anterior and posterior chest views: no uptake (grade 0), uptake equal to that in the thoracic vertebrae (grade 1), uptake higher than that in the thoracic vertebrae (grade 2). If a summed grade of anterior and posterior view was larger than 3, hilar uptake was considered as positive. In forty-four cases (forty-nine hila) with hilar lymph node metastases, positive hilar uptake was found in ten cases (eleven hila), resulting in sensitivity of 22% based on cases and 23% based on hila. In seventy-three cases (one-hundred forty-six hila) without hilar lymph node metastases, positive hilar uptake was found in six cases (ten hila), resulting in specificity of 91% based on cases and 93% based on hila. In comparison to scintigraphic findings of unilaterally positive hilar uptake, findings of bilaterally positive hilar uptake showed significantly lower accuracy in determining presence of hilar lymph node metastases. No definite correlation between hilar uptake and histopathology or 67Ga-citrate uptake in a primary tumor was observed. The results indicate that usefulness of 67Ga-citrate scintigraphy is limited when evaluating hilar lymph node metastases in bronchogenic carcinoma. |
