概括
基于CT的萨尔科佩尼亚分析是可行的,并且可以在患有附质量的女性中复制. 虽然与晚期疾病有关,但它不能改善卵巢癌恶性病的预测,但可以确定需要营养支持的患者.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 手术规划 手术规划
背景情况:
- 卵巢癌是一种致命的妇科恶性瘤,预后取决于诊断阶段.
- 计算机断层扫描 (CT) 有助于分期和外科手术规划的附性质量.
- 低骨肌肉质量 (sarcopenia) 是癌症的已知预后因素,可通过CT测量,但其在副质量中的作用尚不清楚.
研究的目的:
- 评估基于CT的肉症分析在患有附质量的女性中的可行性和可重复性.
- 评估萨科佩尼亚在预测恶性瘤和分期卵巢癌方面的临床实用性.
- 探索开源软件对萨尔科佩尼亚定量化的潜力.
主要方法:
- 对38名怀疑有附质的女性进行前性试点研究.
- 在L3层面的CT图像使用3D切片机进行细分,用于分析皮症.
- 骨肌肉指数 (SMI) 计算;皮症定义为SMI<38.5厘米2/米2.
- 使用布兰德-阿尔特曼图片和科恩的卡帕评估的观察者间协议.
- 使用千平方和ROC分析测试的与瘤阶段和恶性瘤的关联.
主要成果:
- 基于CT的萨尔科佩尼亚分析是可行的和可重复的 (κ = 0.839).
- 萨科佩尼亚与晚期瘤阶段 (P = .028) 和腹膜癌症 (P = .033) 有显著的关联.
- 萨科佩尼亚与组织病理性恶性瘤,淋巴腺病变或相邻的侵袭没有相关性.
- 恶性瘤预测的诊断性能有限.
结论:
- 基于CT的萨尔科佩尼亚分析是可行的,并且可以在患有附质量的女性中复制.
- 麻症与晚期疾病有关,但不提高恶性瘤的预测.
- 萨科佩尼亚不应该指导卵巢癌的手术前风险分层.
- 潜在的实用性在于识别患者进行预康复或营养支持.

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
