概括

68Ga-PSMA PET/CT可用于诊断前列腺癌 (PCa) 和确定临床显著PCa (csPCa) 的可靠性. 特定的SUVmax截止值有助于诊断,特别是可疑病例.

科学领域:

核医学成像技术核医学成像技术
在瘤学瘤学.
放射化学放射化学是指辐射化学.

背景情况:

前列腺癌 (PCa) 诊断依赖于成像和活检,但在识别临床上显著的疾病方面仍然存在挑战.
68Ga标记的前列腺特异性膜抗原正子发射断层扫描/计算机断层扫描 (68Ga-PSMA PET/CT) 提供了一个有前途的成像模式.

研究的目的:

评估68Ga-PSMA PET/CT在前列腺癌诊断中的可靠性.
为了确定适当的SUVmax截止值来区分PCa和临床显著的PCa (csPCa).

主要方法:

在经过直肠超声导向前列腺活检 (TRUS-bx) 后接受68Ga-PSMA PET/CT的84名患者的回顾性分析.
手动将前列腺图划分为每个患者的6个区域,并分析SUVmax值与基因病理学格里森得分相关.
接收器操作特征 (ROC) 曲线分析以确定SUVmax截止值.

主要成果:

与较高等级 (p < 0.001) 相比,格里森等级组1 (GG1) 的平均SUVmax明显较低.
SUVmax截止值为1.0,证明了瘤检测的高精度 (99.4%的灵敏度,92.1%的特异性).
鉴定出SUVmax截止值为4.2,用于检测临床显著的PCa (88.8%的灵敏度,62.4%的特异性).

结论:

68Ga-PSMA PET/CT 是前列腺癌诊断和管理的可靠工具.
这种成像技术对于区分临床显著的PCa和在持续怀疑疾病的患者中特别有用.

Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
