PET/CT在食管癌中的应用进展

Progress in the application of PET/CT in esophageal cancer

食管癌是我国常见的消化道恶性肿瘤,多数患者发现时已处于疾病中晚期。对食管癌的早期诊断、疗效评估是优化治疗策略及改善预后的关键。正电子发射型计算机断层显像/计算机体层成像(positron emission computed tomography/computed tomography,PET/CT)是一种集分子显像功能与解剖结构成像于一体的影像学检查方法,在肿瘤的诊疗过程中显示出重要价值。本文主要探讨PET/CT在食管癌诊断分期、疗效评估、预后预测及放疗计划制定等方面的应用及进展。

Esophageal cancer is a common malignant tumor of the digestive tract in China,and most patients are detected in an advanced stage.Early diagnosis and assessment of the efficacy of esophageal cancer are key to optimizing treatment strategies and improving prognosis.Positron emission computed tomography/computed tomography(PET/CT)is an imaging method that integrates molecular function and anatomical structure,and has shown significant value in the diagnosis and treatment of tumors.This review focuses on the application and progress of PET/CT in the diagnosis and staging of esophageal cancer,assessment of efficacy,prediction of prognosis and planning of radiotherapy.
