摘要:

目的: 评估18F-FDG PET/CT检查的代谢参数[最大标准摄取值(maximum standardized uptake value,SUVmax)、肿瘤代谢体积(metabolic tumour volume,MTV)、肿瘤糖酵解负荷(total lesion glycolysis,TLG)]在自然杀伤(natural killer,NK)/T细胞淋巴瘤患者预后评估中的价值。方法: 回顾性分析27例经病理确诊的NK/T细胞淋巴瘤患者,患者均在治疗前进行了基线PET/CT检查,随后接受相同方案治疗,中位随访23个月,每例患者在随访期间至少进行了一次治疗中或治疗末期的PET/CT评估。统计所有患者的PET/CT代谢参数SUVmax、MTV、TLG以无进展生存(progression-free survival,PFS)期及总生存(overall survival,OS)期为评价指标,进行Kaplan-Meier生存曲线分析。结果: 27例NK/T细胞淋巴瘤患者中5例出现了疾病进展,其中3例死亡。PET/CT检查参数中,MTV、TLG是NK/T细胞淋巴瘤患者PFS的预测因子,MTV>16.97 cm3及TLG>74.70×103预示疾病进展(MTV,P=0.013;TLG,P=0.029),SUVmax则无法预测PFS(P=0.661)。然而,这3项代谢参数均无法预测患者的OS(SUVmax,P=0.293;MTV,P=0.198;TLG,P=0.108)。结论: 18F-FDG PET/CT代谢参数MTV、TLG可能有助于预测NK/T细胞淋巴瘤患者的PFS,而无法预测其OS;SUVmax则在NK/T细胞淋巴瘤预后评估中的价值不大。

Abstract:

Objective: To analyze the prognostic value of metabolic parameters of 18F-FDG PET/CT examination [maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG)] in patients with natural killer (NK)/T-cell lymphoma. Methods: A retrospective analysis of 27 patients with pathologically confirmed NK/T-cell lymphoma who underwent baseline PET/CT before treatment and then receiving the same treatment was performed. The median follow-up was 23 months. Each patient had at least one PET/CT re-assessment during follow-up or at the end of treatment. The PET/CT metabolic parameters SUVmax, MTV and TLG were analyzed statistically. The Kaplan-Meier survival curve was used to assess the progression-free survival (PFS) and overall survival (OS). Results: Of the 27 patients, 5 had disease progression and 3 of them died. Among the PET/CT parameters, MTV and TLG were the predictors of PFS in patients with NK/T-cell lymphoma (MTV: P=0.013, TLG: P=0.029), while SUVmax could not predict PFS (P=0.661). However, none of the 3 metabolic parameters could predict the OS (SUVmax, P=0.293; MTV, P=0.198; TLG, P=0.108). Conclusions: 18F-FDG PET/CT metabolic parameters MTV, TLG may help predicting PFS in patients with NK/T-cell lymphoma, but cannot predict OS; SUVmax is of little value in prognostic prediction of NK/T-cell lymphoma
