PET/CT在胰腺癌临床应用中的进展

Progress in the clinical application of in patients with pancreatic cancer

胰腺癌是一类发病率高、早期诊断困难、治疗疗效不佳的消化系统恶性肿瘤.PET/CT作为现代医学成像重要组成内容之一,将PET的功能显像与CT的解剖成像有机融合,不仅能有效显示肿瘤的代谢、增生、乏氧和细胞凋亡状态,而且能精确显示肿瘤与其周围脏器组织的解剖结构.在胰腺癌患者的诊疗指导、肿瘤分期、疗效监控和预后评价等方面,PET/CT都具有重要的临床应用价值.本文将简要介绍PET/CT在胰腺癌临床应用中的进展情况.

Pancreatic cancer, which has high morbidity, difficult diagnosis, and poor treatment results, is a type of malignant tumor in the digestive system. Positron emission tomographycomputed tomography, an important imaging modality in modern medicine, combines the functional imaging of PET and the anatomic imaging of CT to efficiently image tumor metabolism, proliferation, hypoxia and cell apoptosis. It can also precisely image the anatomic structure of tumors and their adjacent organs or tissues. Positron emission tomography-computed tomography was found to be particularly helpful for guiding diagnosis and therapy, the staging and grading of tumors, monitoring therapy and in evaluating the prognosis of patients with pancreatic cancer.
