| 目的/Objectives |
| 目的1/Narrative objectives1 |
ニボルマブはPD-1免疫チェックポイント阻害剤であり、非小細胞肺癌症例に有効な症例があり、長期に奏功する可能性がある。しかし、その効果の早期の予測はCTなどの通常の検査では困難である。
今回の試験の目的はFDG-PET/MRIの治療前後の変化が長期の奏功を予測可能であるかを検討することである。 |
Nivolumab, a programmed death 1 immune checkpoint inhibitor antibody, was active and durable in some patients with advanced non-small cell lung cancer. However, it is difficult to evaluate early response with conventional imaging (i.e. computed tomography).
The aim of this study is to clarify whether serial change of FDG-PET/MRI findings can predict long term tumor response of nivolumab monotherapy. |

| 主な結果/Results |
NivolumabのORRは32%、DCRは64%であった。PD(9例)とnon-PD(16例)の間で治療前と2週後の変化率に有意差があったのはΔTLG とΔADC、ΔTLG+ΔADCであり、PDを予測する閾値をROC曲線を用いて15%、7%、16.5%に設定したところ、それぞれのnon-PD予測の正診率は76%、84%、92%であった。これらのcut off値で2群に症例を分けると、有意にPFSに差が見られた(ΔTLG 8.1 vs 1.9 mo, P=0.031; ΔADC 9.1 vs 1.9 mo, P=0.004; ΔTLG+ΔADC 9.0 vs 1.8 mo, P<0.001) |
Patients with non-progressive disease (non-PD) had significantly decreased TLG, increased ADCmean (that is, negative dADCmean), and lower dTLG+dADCmean than patients with PD. Among the parameters tested, receiver operating characteristic curve analysis revealed that a cut-off value of 16.5 for dTLG+dADCmean had the highest accuracy (92%) for distinguishing between non-PD and PD patients. |
