摘  要:目的探讨非霍奇金淋巴瘤(NHL)患者在自体干细胞移植(ASCT)前后行^18F-脱氧葡萄糖(FDG)符合线路显像对于预测患者无进展生存期(PFS)的价值,并将结果与CT检查进行对比分析。方法29例经病理检查证实的NHL患者在ASCT前后均进行^18F-FDG符合线路显像与CT检查,ASCT后随访时间均〉1年。分别计算^18F-FDG符合线路显像与CT检查的阳性预测值(PPV)、阴性预测值(NPV)和准确性,采用,检验比较两者的结果,并采用Kaplan—Meier生存分析法行PFS分析。结果ASCT前,^18F-FDG显像的PPV、NPV和准确性分别为85.7%(12/14)、73.3%(11/15)和79.3%(23/29),高于CT检查的55.6%(10/18)、45.5%(5/11)和51.7%(15/29);而在ASCT后,^18F-FDG显像的PPV、NPV和准确性分别为92.3%(12/13)、75.0%(12/16)和82.8%(24/29),也分别高于CT检查的62.5%(10/16),53.8%(7/13)和58.6%(17/29);^18F-FDG显像和CT两者评价准确性差异有统计学意义(χ^2值分别为4.884和4.077,P均〈0.05)。ASCT前后^18F—FDG显像阴性与阳性病例的PFS差异也有统计学意义(χ^2值分别为15.839和20.219,P均〈0.005),而同期CT检查的阴性与阳性病例PFS差异无统计学意义(χ^2=2.468,P=0.116)。ASCT前后,^18F—FDG显像阴性和阳性患者的1年无进展生存率分别为86.7%(13/15)、87.5%(14/16)和28.6%(4/14)、23.1%(3/13)。结论ASCT前后^18F—FDG符合线路显像均具有预测NHL预后的价值,且均优于CT检查。Objective Evaluation of therapeutic response in non-Hodgkin's lymphoma (NHL) patients with autologous stem cell transplantation (ASCT) is of great clinical significance. But the exact role of ^18F-fluorodeoxyglucose (FDG) imaging in NHL associated with ASCT is not clear. This study assessed the value of ^18F-FDG coincidence SPECT imaging prior to and after ASCT for prediction of progression-free survival (PFS) in NHL, as well as the predictive values of CT and ^18 F-FDG SPECT imaging in these patients. Methods ^18F-FDG coincidence SPECT imaging and CT were performed in 29 patients with pathologically confirmed NHL prior to and after ASCT. No patients were lost to follow-up earlier than 1 year after ASCT. Positive predictive value (PPV) , negative predictive value (NPV) and accuracy of ^18F-FDG coincidence SPECT imaging were compared to the results of CT using the χ^2-test. The results of ^18F-FDG scans and CT were correlated with PFS using Kaplan-Meier survival analysis. Results ^18F-FDG coincidence SPECT imaging before ASCT showed PPV, NPV and accuracy [ 85.7% (12/14) , 73.3% ( 11/15 ) and 79.3% ( 23/ 29)] higher than CT [55.6% (10/18), 45.5% (5/11) and 51.7% ( 15/29), respectively]. After ASCT, ^18F-FDG imaging also showed PPV, NPV and accuracy [92.3% (12/13) , 75.0% (12/16) and 82. 8% (24/29) ] higher than CT[62.5% ( 10/16), 53.8% (7/13) and 58.6% ( 17/29), respectively]. However, only the differences in accuracy between ^18F-FDG SPECT imaging and CT betore and after ASCT were significant ( χ^2 =4. 884, 4.077, all P 〈 0.05). ^18F-FDG imaging results before or after ASCT were strongly correlated with PFS (χ^2 = 15. 839, 20. 219, all P 〈0. 005, significant ) but not CT (χ^2 =2. 468, P = 0. 116, not significant). The 1-year PFS rate for ^18F-FDG-negative patients was 86.7% (13/15) and 28.6% (4/14) for ^18F-FDG-positive patients before ASCT. The 1-year PFS rate for ^18F-FDG-negative patients was87.5% (14/16) a
