概括
代谢学表明,通过分析血液和尿液生物标志物,有望检测显著的前列腺癌 (PC). 这些新的代谢面板可能比前列腺特异性抗原 (PSA) 测试提供更高的准确性.
科学领域:
- 生物化学 生物化学
- 在瘤学瘤学.
- 生物标志物发现发现
背景情况:
- 前列腺癌 (PC) 是男性癌症死亡的主要原因.
- 前列腺特异性抗原 (PSA) 检测缺乏特异性,导致过度诊断和过度治疗临床无意义的PC (isPC).
- 磁共振成像 (MRI) 有助于检测,但成本昂贵且存在局限性.
研究的目的:
- 审查血液和尿液代谢学研究,以确定显著PC (sPC) 的生物标志物.
- 评估代谢学作为PC风险分层工具的潜力.
- 为了比较新陈代谢面板与PSA测试等传统方法的疗效.
主要方法:
- 对调查PC中的代谢组分的研究进行系统审查.
- 分析PC患者血液和尿液样本中的代谢物变化.
- 对已识别的代谢面板进行评估,以确定sPC预测准确度.
主要成果:
- 在sPC中显著的代谢物变化涉及脂肪酸,脂,糖溶解,酸循环, purin/pyrimidine以及tyrosine/phenylalanine代谢.
- 在sPC患者中发现乳酸和氨酸的增加,氨酸,丁和氨酸水平的降低.
- 代谢面板,特别是基于尿液的测试,与PSA相比,表现出更好的预测性能,特别是与临床因素相结合时.
结论:
- 基于代谢学的液体活检具有改善sPC检测的巨大潜力.
- 协议的标准化,与MRI的整合,以及大型队列的验证对于临床翻译至关重要.
- 需要进一步的研究来克服方法的异质性,并提高模型的可信性,以便广泛采用.

Serum Laboratory Studies, Stool Test, Breath Test
Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...
Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
