概括
区域和前列腺活检 (RSB) 比向活检 (TB) 更有效地检测高PSA水平 (≥20 ng/mL) 的患者的临床显著前列腺癌 (csPCa). 周围活检对于特定的患者亚组至关重要.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 以前的研究表明,区域和前列腺活检 (RSB) 优于针对性活检 (TB) 和系统活检 (SB) 的前列腺特异性抗原 (PSA) 水平 4-20 ng/mL.
- 在PSA水平≥20 ng/mL的患者中,RSB的疗效仍在研究中.
研究的目的:
- 为了比较RSB与TB在检测具有临床意义的前列腺癌 (csPCa) 在PSA水平≥20 ng/mL的患者中的疗效.
- 评估补充系统活检 (SB) 与RSB和结核病结合的作用.
主要方法:
- 一个前性,单中心,随机对照试验,涉及PSA> 20 ng/mL和可疑MRI发现的患者.
- 参与者被随机分配到RSB或TB,在所有情况下都进行了SB.
- 主要终点是cspca的检测率 (ISUP等级≥2).
主要成果:
- 与结核病 (90.2%与82.9%,p=0.01) 和SB (90.2%与82.5%,p=0.01) 相比,RSB显示了显著更高的csPCa检测率.
- 补充SB在结核病组中改善了csPCa检测,但在RSB组中没有.
- 在 PSA 20-50 ng/mL,PI-RADS 3 病变,前列腺体积> 45 mL,PSA 密度< 1.0 ng/mL/cc 的小组中,RSB 特别有效.
结论:
- 在高PSA水平 (≥20 ng/mL) 的患者中检测CSPCa方面,RSB优于TB.
- 周周活检对于改善特定患者群体的csPCa检测至关重要,包括那些PSA为20-50 ng/mL,前列腺体积较大,PSA密度低,PI-RADS得分低的患者群体.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...
