To investigate the tolerance and efficacy of HIFU ablation for uterine fibroids with a non-perfused volume ratio (NPVR) ≥ 90%.
A prospective cohort study of 2411 patients from 20 clinical centers was available. Contrast-enhanced MRI was used to assess the non-perfused volume ratio (NPVR). The International Society of Interventional Radiotherapy (SIR) complication grading system was used as the tolerance index. Uterine Fibroids-related Symptoms-Quality of Life (UFS-QoL) was used to evaluate the efficacy.
A total of 1352 patients underwent USgHIFU ablation treatment enrolled, NPVR was median 91.9% (IQR, 81.4%,100.0%). There was 761 case (56.3%) in the NPVR ≥ 90% group in which 17.5% case experienced SIR-B abdominal pain, 591 cases (43.7%) in NPVR < 90% group in which 9.3% case had SIR-B abdominal pain. There were statistically differences in the improvement degree of UFS at 12 months among the four subgroups (NPVR < 70%, 70%-80%, 80%-90%, 90%-100%) (all < 0.05).
Patients with NPVR ≥ 90% had a higher incidence of SIR-B lower abdominal pain. NPVR was positively correlated with the degree of symptom relief at 12 months, and NPVR ≥ 90% was more likely to obtain better clinical symptom relief.
探讨非灌注体积比(NPVR)≥90%的子宫肌瘤患者接受 HIFU 消融治疗的耐受性和疗效。
本研究为 20 个临床中心的 2411 例患者的前瞻性队列研究。采用增强 MRI 评估非灌注体积比(NPVR)。采用国际介入放射治疗学会(SIR)并发症分级系统作为耐受指数。采用子宫肌瘤相关症状生活质量(UFS-QoL)量表评估疗效。
共纳入 1352 例行 USgHIFU 消融治疗的患者,NPVR 中位数为 91.9%(IQR,81.4%,100.0%)。NPVR≥90%组 761 例(56.3%)中有 17.5%发生 SIR-B 级腹痛,NPVR<90%组 591 例(43.7%)中有 9.3%发生 SIR-B 级腹痛。四个亚组(NPVR<70%、70%-80%、80%-90%、90%-100%)在 12 个月时 UFS 改善程度存在统计学差异(均 P<0.05)。
NPVR≥90%的患者发生 SIR-B 级下腹痛的发生率较高。NPVR 与 12 个月时症状缓解程度呈正相关,NPVR≥90%更有可能获得更好的临床症状缓解。
