概括
新型索马托他类型的帕尔图索丁不干扰放射性连接体的吸收,与八丁不同. 这一发现表明,在神经内分泌瘤的受体放射性核素疗法 (PRRT) 期间,帕尔图索丁可能允许持续治疗.
科学领域:
- 在瘤学瘤学.
- 放射化学 放射化学是指辐射化学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 索马托斯塔丁受体类似物对于治疗转移性胃肠胰腺神经内分泌瘤 (GEP-NETs) 至关重要,有助于控制症状和抑制瘤生长.
- 在受体放射性核酸治疗 (PRRT) 之前,必须暂停目前的类型,因为可能会和体静止素受体2 (SSTR2),从而阻碍放射性对象的结合.
研究的目的:
- 为了比较新型索马托斯胺类同类药物帕尔图索丁与奥克特胺对18F-SiTATE放射性体吸收和GEP-NET细胞活性的影响.
- 评估paltusotine与PRRT同时使用的可能性.
主要方法:
- 帕尔图索丁和奥克特雷奥提德在各种度下使用18F-SiTATE吸收试验测试了BON-1细胞过度表达人体体静止素受体2 (hSSTR2).
- 对各种神经内分泌瘤 (NET) 细胞系和13种患者衍生GEP-NET初级培养进行了细胞活力测试.
主要成果:
- 低,临床相关的度的paltusotine没有影响细胞放射性体的吸收.
- 在低度和高度下,八丁显著降低了放射性体的吸收.
- 虽然这两种类型的药物在NET细胞系上表现出有限的体外抗瘤作用,但在患者衍生GEP-NET培养物中,帕尔图索丁略有降低了细胞活力.
结论:
- 帕尔图索丁治疗在体外没有显著抑制18F-SiTATE与SSTR2的结合,这表明它不会干扰SSTR2向.
- 这种缺乏干扰表明paltusotine可能在PRRT期间继续使用,可能会改善GEP-NET癌症综合征患者的症状管理.

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
