Abstract：Objective To improve the knowledge and diagnostic accuracy of the hepatoid adenocarcinoma of the stomach via-investigating the characteristics of 18F-FDG PET/CT imaging of this disease in combination with the level of the serum AFP Methods The 18F-FDG PET/CT data of 5 patients with hepatoid adenocarcinoma of the stomach confirmed by pathology were collected,and the clinical manifestations,location and shapes of primary focus and maximum standard uptake value(SUVmax),the level of the tumor markers and the prognosis were analyzed.Results Three cases were located in gastric antrum,two cases in gastric cardia-body.The range of SUVmax in five cases was 7.58 to 23.6,and the average value was(13.8±6.4).The median survival time was 8 months.Conclusion As a rare special type of cancer with no special symptoms,hepatoid adeno-carcinoma of the stomach has strong invasiveness.By combining the imaging and pathology,we can often make the diagnosis of the hepatoid adenocarcinoma of the stomach.If patients have no diseases of the liver,the increase of serum AFP is an important diagnostic clue.
