胃癌是我国常见的恶性肿瘤,具有发病率高、生存率低等特点,其10年存活率约15%,因此需要及时准确的诊断和治疗。在近几十年中,正电子发射断层扫描(PET)使用18F-氟脱氧葡萄糖(18F-FDG)作为示踪剂已被证明可在多种恶性肿瘤的诊断和评估中提供关于肿瘤代谢的信息。然而,由于胃粘膜的物理摄取和自主运动等原因,某些类型的胃恶性肿瘤会影响胃癌的18F-FDG检测能力。因此,寻找更具有肿瘤特异性的PET-CT显像剂以弥补18F-FDG的不足是目前核医学研究的重点。本文就其在胃癌示踪中的应用现状及前景做一综述。

Gastric cancer is a common malignant tumor in China, which has the characteristics of low survival rate and high morbidity, and its 10-year survival rate is about 15%. Therefore, it needs timely and accurate diagnosis and treatment. In recent decades, positron emission tomography (PET) using 18F-fluorine deoxidization glucose (18F-FDG) as a tracer has been proved to be available in a variety of malignant tumor diagnosis and evaluation to provide information about tumor metabolism. However, because of the physical uptake of gastric mucosa and voluntary exercise, some types of gastric malignant tumors may affect the detection ability of 18F-FDG in gastric cancer. Therefore, searching for more tumor-specific PET-CT imaging agents to make up for the deficiency of 18F-FDG is the focus of current nuclear medicine research. In this paper, the application status and prospect of this method in tracer of gastric cancer are reviewed.
