目的探讨18F-FDG PET/CT检查在胃癌诊断和分期中的应用价值。方法回顾性分析27例临床疑诊为胃癌患者的PET/CT检查结果,并与胃镜及手术病理和随访结果对照。结果PET/CT诊断胃癌的灵敏度为88.4%,准确性85.1%,3例假阴性原发灶直径均为1cm(T1期),2例为印戎细胞癌。1例假阳性手术后证实为胃溃疡伴炎症;②术后病理证实16例胃局部淋巴结转移,PET/CT检出12例,灵敏度为75%;③27例患者中PET/CT检出5例有肝脏、肺、骨.腹腔、后腹膜淋巴结等远处转移,其中4例由于的PET/CT结果改变治疗策略。结论PET/CT对胃癌是一种较为灵敏,可靠的检查方法,对术前分期具有重要的临床意义。
Objective To investigate the value of 18F-FDG PET / CT in the diagnosis and staging of gastric cancer. Methods A retrospective analysis of 27 cases of clinically suspected patients with gastric cancer PET / CT examination results and gastroscopy and surgical pathology and follow-up results were compared. Results The sensitivity of PET / CT in the diagnosis of gastric cancer was 88.4% and the accuracy was 85.1%. The diameters of three false-negative primary lesions were all 1 cm (T1 stage) and 2 cases were Rongjong cell carcinoma. 1 case of false-positive surgery confirmed gastric ulcer with inflammation; ② pathological confirmed 16 cases of gastric lymph node metastasis, PET / CT detected in 12 cases, the sensitivity was 75%; ③ 27 cases of PET / CT detected in 5 cases of liver , Lung, bone, peritoneal cavity, retroperitoneal lymph nodes and other distant metastases, of which 4 cases changed the treatment strategy due to the PET / CT results. Conclusion PET / CT is a sensitive and reliable method for gastric cancer. It has important clinical significance for preoperative staging.
