概括
结合膀成像报告和数据系统 (VI- RADS) 评分和血清细胞素片段19 (CYFRA 21-1) 水平,可显著改善膀癌生存率的预测. 这种综合方法为肌肉侵入性膀癌患者提供了更高的预后准确性.
科学领域:
- 癌症学
- 放射学
- 生物标志物
背景情况:
- 膀成像报告和数据系统 (VI-RADS) 用于检测肌肉侵入性膀癌.
- 将成像数据与分子生物标志物整合可能会增加膀癌风险分层.
- 血清细胞蛋白碎片19 (CYFRA 21-1) 是膀癌的临床相关生物标志物.
研究的目的:
- 在膀癌患者中评估VI- RADS评分和血清CYFRA21-1水平的综合预后值.
- 与单个参数相比,确定这种组合是否能改善整体存活率的预测.
主要方法:
- 对134名经过尿道切除,核磁共振和术后血清CYFRA21-1测量的膀癌患者进行了回顾性分析.
- 接收器操作特征 (ROC) 曲线分析以确定VI-RADS (≥4) 和CYFRA21-1 (≥1. 8 ng/ mL) 的最佳预后切断值.
- 多变量考克斯比例危险分析,以评估高VI-RADS和CYFRA 21-1对OS的影响.
主要成果:
- 患有高VI- RADS评分 (≥4) 和高CYFRA21- 1水平 (≥1. 8 ng/ ml) 的患者表现出明显较低的一年,两年和三年生存率 (42. 9%,16. 7%,8. 3%).
- 高VI-RADS和高CYFRA21- 1的组合与最差的OS相关 (危险比率: 7. 51; p = 0. 002).
- 与单个标志物相比,这种综合方法显示出更高的预后准确性.
结论:
- 结合VI-RADS和血清CYFRA21-1水平显著提高了膀癌的预后准确性.
- 这种综合方法对指导个性化治疗策略具有潜在的临床实用性.
- 局限性包括可追溯设计和缺乏外部验证,需要进一步研究.

Imaging Studies VI: Voiding Cystourethrography and Cystography
112
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography
146
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
