西班牙CEU聖巴勃羅大學José A. Obeso團隊研究了聚焦超聲丘腦底切除術治療帕金森病的臨床效果。2020年12月24日,該研究發表在《新英格蘭醫學雜誌》上。
丘腦底核是腦深部刺激治療帕金森病主要運動特徵的首選神經外科靶點。聚焦超聲是一種成像引導的方法,用於治療包括丘腦底核在內的大腦深部結構中的病變。
研究組招募患有嚴重不對稱帕金森氏症的患者,他們的運動體徵不能完全通過藥物控制,或者不適合進行深部腦刺激手術,將其按2:1隨機分組,在其主要運動體徵對側進行聚焦超聲丘腦底切除術或假手術。主要療效結局為運動障礙學會-統一帕金森病評定量表(MDS-UPDRS)運動評分在停用藥物狀態下受影響較大的身體一側(範圍為0-44分,分數越高,表明帕金森病越嚴重)的組間差異。
在40例入選患者中,27例接受聚焦超聲丘腦底切除術(主動治療),13例接受假手術(對照組)。積極治療組患側的MDS-UPDRS III平均得分從基線時的19.9分降至4個月時的9.9分,對照組從18.7分降至17.1分,組間差異顯著。積極治療組的不良事件是6例患者處於停藥狀態的運動障礙,6例患者處於服藥狀態的運動障礙,4個月時分別有3例和1例患者症狀持續;有5例患者治療側乏力,4個月時有2例症狀持續;語言障礙15例,4個月時有3例症狀持續;面部無力3例,4個月時有1例症狀持續;步態障礙13例,4個月時有2例症狀持續。在積極治療組的6名患者中,一些缺陷症狀持續至12個月。
研究結果表明,單側半球聚焦超聲丘腦底切除術改善了帕金森病患者的運動特徵。不良反應包括言語和步態障礙、治療側乏力和運動障礙。

Abstract:
Background
The subthalamic nucleus is the preferred neurosurgical target for deep-brain stimulation to treat cardinal motor features of Parkinson’s disease. Focused ultrasound is an imaging-guided method for creating therapeutic lesions in deep-brain structures, including the subthalamic nucleus.
Methods
We randomly assigned, in a 2:1 ratio, patients with markedly asymmetric Parkinson’s disease who had motor signs not fully controlled by medication or who were ineligible for deep-brain stimulation surgery to undergo focused ultrasound subthalamotomy on the side opposite their main motor signs or a sham procedure. The primary efficacy outcome was the between-group difference in the change from baseline to 4 months in the Movement Disorder Society–Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) motor score (i.e., part III) for the more affected body side (range, 0 to 44, with higher scores indicating worse parkinsonism) in the off-medication state. The primary safety outcome (procedure-related complications) was assessed at 4 months.
Results
Among 40 enrolled patients, 27 were assigned to focused ultrasound subthalamotomy (active treatment) and 13 to the sham procedure (control). The mean MDS-UPDRS III score for the more affected side decreased from 19.9 at baseline to 9.9 at 4 months in the active-treatment group (least-squares mean difference, 9.8 points; 95% confidence interval [CI], 8.6 to 11.1) and from 18.7 to 17.1 in the control group (least-squares mean difference, 1.7 points; 95% CI, 0.0 to 3.5); the between-group difference was 8.1 points (95% CI, 6.0 to 10.3; P<0.001). Adverse events in the active-treatment group were dyskinesia in the off-medication state in 6 patients and in the on-medication state in 6, which persisted in 3 and 1, respectively, at 4 months; weakness on the treated side in 5 patients, which persisted in 2 at 4 months; speech disturbance in 15 patients, which persisted in 3 at 4 months; facial weakness in 3 patients, which persisted in 1 at 4 months; and gait disturbance in 13 patients, which persisted in 2 at 4 months. In 6 patients in the active-treatment group, some of these deficits were present at 12 months.
Conclusions
Focused ultrasound subthalamotomy in one hemisphere improved motor features of Parkinson’s disease in selected patients with asymmetric signs. Adverse events included speech and gait disturbances, weakness on the treated side, and dyskinesia.
