Sinusoidal obstruction syndrome (SOS) refers to liver injury caused by hematopoietic stem cell transplantation (HSCT) and anticancer drugs including oxaliplatin. Increased splenic volume (SV) on computed tomography (CT) indicates oxaliplatin-induced SOS. Similarly, ultrasonography and liver stiffness measurement (LSM) by shear-wave elastography (SWE) can help diagnose SOS after HSCT; however, their usefulness for diagnosing oxaliplatin-induced SOS remains unclear. We investigated the usefulness of the Hokkaido ultrasonography-based scoring system with 10 ultrasonographic parameters (HokUS-10) and SWE in diagnosing oxaliplatin-induced SOS early.
In this prospective observational study, ultrasonography and SWE were performed before and at 2, 4, and 6 months after oxaliplatin-based chemotherapy. HokUS-10 was used for assessment. CT volumetry of the SV was performed in clinical practice, and an SV increase ≥ 30% was considered the diagnostic indicator of oxaliplatin-induced SOS. We assessed whether HokUS-10 and SWE can lead to an early detection of oxaliplatin-induced SOS before an increased SV on CT.
Of the 30 enrolled patients with gastrointestinal cancers, 12 (40.0%) with an SV increase ≥ 30% on CT were diagnosed with SOS. The HokUS-10 score was not correlated with an SV increase ≥ 30% (r = 0.18). The change in rate of three HokUS-10 parameters were correlated with an SV increase ≥ 30% (r = 0.32-0.41). The change in rate of LSM by SWE was correlated with an SV increase ≥ 30% (r = 0.40).
The usefulness of HokUS-10 score was not demonstrated; however, some HokUS-10 parameters and SWE could be useful for the early diagnosis of oxaliplatin-induced SOS.
窦状隙阻塞综合征(SOS)是指造血干细胞移植(HSCT)和包括奥沙利铂在内的抗癌药物引起的肝损伤。CT 上脾脏体积(SV)增加表明奥沙利铂诱导的 SOS。同样,超声和剪切波弹性成像(SWE)的肝硬度测量(LSM)可帮助诊断 HSCT 后的 SOS;然而,它们在诊断奥沙利铂诱导的 SOS 中的作用尚不清楚。我们研究了基于北海道超声的评分系统(HokUS-10)和 SWE 在早期诊断奥沙利铂诱导的 SOS 中的应用。
在这项前瞻性观察研究中,在奥沙利铂化疗前和化疗后 2、4 和 6 个月进行超声和 SWE。采用 HokUS-10 进行评估。SV 的 CT 体积在临床实践中进行,SV 增加≥30%被认为是奥沙利铂诱导的 SOS 的诊断指标。我们评估了 HokUS-10 和 SWE 是否可以在 CT 上 SV 增加之前更早地检测奥沙利铂诱导的 SOS。
在 30 名胃肠道癌症患者中,12 名(40.0%)CT 上 SV 增加≥30%的患者被诊断为 SOS。HokUS-10 评分与 SV 增加≥30%无相关性(r=0.18)。三个 HokUS-10 参数的变化率与 SV 增加≥30%相关(r=0.32-0.41)。SWE 的 LSM 变化率与 SV 增加≥30%相关(r=0.40)。
HokUS-10 评分的实用性未得到证实;然而,一些 HokUS-10 参数和 SWE 可能对奥沙利铂诱导的 SOS 的早期诊断有用。
