目的应用18F-FDG PET/CT(PET/CT)与多层螺旋CT对进展期胃癌术前TNM分期进行对比研究,以期更客观地评估术前分期,指导治疗.方法对术前行PET/CT检查的39例及MSCT检查的40例进展期胃癌,分别进行术前TNM分期,将检测结果与术中所见及病理进行对照.结果 PET/CT对原发灶、区域淋巴结、N3转移淋巴结的准确率分别为92.3%、66.7%、100.0%;而MSCT诊断的准确率分别为82.0%、50.0%、62.5%.结论 (1)PET/CT和多层螺旋CT对原发灶、区域淋巴结转移的准确率都较高,差异无统计学意义,由于多层螺旋CT临床应用广泛且费用远低于PET/CT,是首选的检测手段;(2)PET/CT对N3转移淋巴结、远处转移灶检测的准确率明显高于多层螺旋CT,为临床提供更为全面客观的术前分期,指导治疗;(3)由于PET/CT也存在一定假阴性,结合腹腔镜检可减少或避免不必要的剖腹术.

Objective Evaluate the diagnostic value of PET/CT in the preoperative advanced gastric carcinoma comparing with mult;-slice spiral computed tomography. Methods Thirty-nine advanced gastric carcinoma patients taking PET/CT and abstract 40 advanced gastric carcinoma patients performing MSCT before operation,were done the TNM staging, and the Results were compared with the operation histopathology. Results For diagnosing primary lesions, regional lymph nodes, N3 lymph nodes ,PET/CT was accurate in 92.3% , 66.7% and 100.0%.Instead, MSCT was accurate in 82.0% , 50.0% and 62.5%. Conclusions (1) PET/CT and MSCT have high accuracy in diagnosing primary lesions and regional lymph nodes. But for detecting the N3 lymph nodes and distant metastasis, PET/CT has higher accuracy than MSCT. PET/CT combining abdominoscopy may decrease or avoid exploratory laparotomy.
