OBJECTIVE
High-dose chemotherapy (HDC) followed by autologous hematopoietic stem cell transplantation (auto-HSCT) plays an important role in improving outcomes of diffuse large B cell lymphoma (DLBCL) patients. F-fluorodeoxyglucose (F-FDG) positron emission tomography (PET)/computed tomography (CT) has been widely accepted in response assessment and prediction of prognosis in DLBCL. Here, we report the value of F-FDG PET/CT pre- and post-HSCT in predicting outcomes of patients with DLBCL.
METHODS
DLBCL patients who had PET/CT scan before and after HSCT were included. PET results were interpreted based upon Deauville criteria. The prognostic value of F-FDG PET/CT in auto-HSCT was evaluated.
RESULTS
Eighty-four patients were enrolled. In univariate analysis, pre- and post-HSCT PET findings were correlated with 3-year progression-free survival (PFS) [hazard ratio (HR)=4.391, P=0.001; HR=7.607, P<0.001] and overall survival (OS) (HR=4.792, P=0.008; HR=26.138, P<0.001). Patients receiving upfront auto-HSCT after first-line treatment had better outcomes than relapsed/refractory DLBCL patients (3-year PFS, P<0.001; 3-year OS, P<0.001). In the relapsed/refractory patients, pre- and post-HSCT PET findings were also associated with 3-year PFS (P=0.003. P<0.001) and OS (P=0.027. P<0.001). A significant correlation was observed between clinical response to chemotherapy before auto-HSCT and outcomes of patients in the entire cohort (3-year PFS, P<0.001; 3-year OS, P<0.001) and in the subgroup of 21 patients with positive pre-HSCT PET (3-year PFS, P=0.084; 3-year OS, P=0.240). A significant association between survival and post-HSCT PET findings was observed in multivariate analysis (HR=5.168, P<0.001).
CONCLUSIONS
PET results before and after HSCT are useful prognostic factors for DLBCL patients receiving HSCT. Patients who responded to chemotherapy, even those with positive pre-HSCT PET, are appropriate candidates for auto-HSCT.
目的
大剂量化疗（HDC）后行自体造血干细胞移植（auto-HSCT）在改善弥漫性大B细胞淋巴瘤（DLBCL）患者的预后方面发挥着重要作用。F-氟脱氧葡萄糖（F-FDG）正电子发射断层扫描（PET）/计算机断层扫描（CT）已在DLBCL的疗效评估和预后预测中得到广泛认可。在此，我们报告HSCT前后F-FDG PET/CT在预测DLBCL患者预后方面的价值。
方法
纳入在HSCT前后进行PET/CT扫描的DLBCL患者。PET结果根据多维尔标准进行解读。评估F-FDG PET/CT在auto-HSCT中的预后价值。
结果
共纳入84例患者。单因素分析显示，HSCT前后的PET结果与3年无进展生存期（PFS）相关[风险比（HR）=4.391，P=0.001；HR=7.607，P<0.001]和总生存期（OS）（HR=4.792，P=0.008；HR=26.138，P<0.001）。一线治疗后接受 upfront auto-HSCT的患者比复发/难治性DLBCL患者预后更好（3年PFS，P<0.001；3年OS, P<0.001）。在复发/难治性患者中，HSCT前后的PET结果也与3年PFS（P=0.003，P<0.001）和OS（P=0.027，P<0.001）相关。auto-HSCT前化疗的临床反应与整个队列患者的预后（3年PFS，P<0.001；3年OS，P<0.001）以及21例HSCT前PET阳性患者亚组的预后（3年PFS，P=0.084；3年OS，P=0.240）之间存在显著相关性。多因素分析显示生存与HSCT后PET结果之间存在显著关联（HR=5.168，P<0.001）。
结论
HSCT前后的PET结果是接受HSCT的DLBCL患者有用的预后因素。对化疗有反应的患者，即使是HSCT前PET阳性的患者，也是auto-HSCT的合适候选者。
