概括

在低剂量计算机断层扫描 (LDCT) 查之前,胸部X射线 (CXR) 选可以减少不必要的肺癌手术,而不会损害预后. 这种方法有助于更好地选择患者,避免过度诊断和过度治疗查计划.

科学领域:

肺部病理学肺部病理学
放射学放射学是一门学科.
在瘤学瘤学.

背景情况:

低剂量计算机断层扫描 (LDCT) 查有效降低了肺癌死亡率.
在接受LDCT查的亚洲人群中,亚固体结节 (SSN) 容易被过度诊断和过度治疗.
胸部X射线 (CXR) 选可以改善患者对LDCT查的选择.

研究的目的:

评估CXR选是否可以提高LDCT对SSN的选中患者的选择.
评估CXR选对肺癌预后,复发率和肺腺癌的组织病理谱的影响.
为了确定CXR选是否减少不必要的干预和过度诊断.

主要方法:

追溯队列研究,将直接LDCT查与LDCT和CXR选对506名SSNs≤3cm的患者进行比较.
倾向性得分匹配 (PSM) 创建了97对匹配的对来进行平衡的比较.
主要结局包括肺癌预后,复发和组织病理学来评估过度诊断.

主要成果:

与直接LDCT组 (37.1%) 不同,CXR选组在切除的病变中没有发现现场腺癌 (AIS) 或非典型腺瘤性增生 (AAH) 的病例.
两组之间没有观察到无病生存率或复发率的显著差异.
长期生存分析 (15年) 显示,这两组的生存率同样高,表明CXR选不会对预后产生负面影响.

结论:

"CXR选"作为LDCT肺癌查的有效初步步骤,特别是在非吸烟的亚洲高风险人群中.
这一策略可以显著减少不必要的外科手术,同时保持诊断的有效性.
需要进一步的前性研究来确认长期的安全性,成本效益和临床可接受性.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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...

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...
