| Abstract | 「要旨」PETの利用が肺癌診療に及ぼす医療経済効果と, PETを用いた最適な肺癌診断のプロトコールについて, 検討した. 50万人の有所見母集団から34,800の肺癌と465,200の良性疾患を診断する過程をシミュレーションした. 診断される肺癌および良性疾患の患者数, 検査費用の合計, またステージ診断では手術適応の適正さと費用を求めた. 鑑別診断にPETを用いると, 気管支鏡・生検の総件数が4分の1に, 良性疾患の占める割合も半分に減少し, 不要な検査が節約できた. しかし, 気管支鏡・生検の費用がPETの費用よりも安いために, PETを用いると検査費用合計は25%割高となった. 肺癌と確定した患者に, 骨シンチグラフィや腹部CT・MRIの代わりに全身PETでステージ診断を行うと, 検査費用を5%節約でき, 不要な手術が67%減少し, 真の適応の増加により総手術件数は微増したが, 医療費全体として25%節約できた. 結論:肺癌患者に全身PETによるステージ診断を行うことにより, 診断精度の向上, 検査費用の節約, 不要な手術の節約, 医療費の節約が期待できる. |

| Abstract | [Summary]Several studies have shown that FDG-PET is more accurate than CT for the differential diagnosis and for the staging of lung cancer. We have analyzed potential effect of FDG-PET on the medical cost for the management of patients suspected of lung cancer. In the differential diagnosis, chest CT plus FDG-PET protocol reduced the number of bronchofiberscope(BFS)and biopsy by one fourth of that in the conventional protocol using CT alone. PET protocol reduced unnecessary examinations for the patients of benign disease, however, it increased the total cost of examinations by 25% due to the higher cost of PET than that of BFS and biopsy in Japan. In the staging of lung cancer, PBT protocol improved accuracy of staging, reduced unnecessary surgery by 67%, and showed a saving of the cost of examination by 5%, and the total medical cost by 2.5% compared to that in the conventional protocol using CT, brain MRI and bone scan. Conclusion:Use of FDG-PET for the staging may contribute to the improvement of patient management of lung cancer patients also to the saving of the medical cost. |
