18F-FDG PET/CT显像在恶性胸膜间皮瘤诊断中的价值

Objective Malignant pleural mesothelioma (MPM) is an uncommon neoplasm arising from mesothelial cells of the pleura. The prognosis is poor with median survival of 4- 12 months. The aim of this study was to evaluate the clinic value of 18F-fluorodeoxyglucose (FDG) PET/CT imaging in the diagno-sis and to staging of MPM and to determine if the mean standardized uptake value (SUVmax) of primary tumor correlates with staging and prognosis. Methods Study was conducted retrospectively including 17 pa-tients with clinical suspicion of MPM from 2002 to 2008. Twelve cases of MPM and 5 cases benign pleural pa-thology were proven by histopathology and clinical follow-up. 18F-FDG PET/CT imaging was performed 1 h af-ter injection of 7.4 MBq/kg 18F-FDG. Patients with MPM confirmed by histopatholagy were divided into two groups: with and without metastasis. PET/CT findings were analyzed to determine if SUVmax of primary tumor correlates with staging and prognosis. Receiver operating characteristic (ROC) curve of SUVmax of primary tumor was evaluated to determine if it was a predictor of metastasis and survival time. Results The difference in SUVmax between MPM and benign pleural were statistical significant (5.78±1.81 vs 2.72± 2.51, t = 2. 8, P < 0.05). The diagnostic sensitivity, specificity and accuracy of 18F-FDG PET/CT imaging for MPM were 100% (12/12) , 4/5 and 94% (16/17). All 7 cases of bone and lymph node metastases were detected by 18F-FDG PET/CT imaging. Area under the curve (AUC) was 0.80. Conclusions 18F-FDG PET/CT imaging is useful in the diagnosis and staging of MPM. High SUVmax in the primary tumor correlates well with prognosis and predication of a greater propensity to have nodal and distant metastasis.

隐蔽区胃癌的影像检查与诊断

目的:探讨隐蔽区胃癌的影像检查技巧与诊断要点。方法:20例隐蔽区胃癌均行钡剂造影检查,发生于胃底后壁7例,胃底后壁小弯侧13例,其中贲门管受累9例。20例中16例术前行胃镜检查,全部病例均经胃肠钡餐造影检查。结果:20例胃底后壁癌19例手术切除,其中2例病变与脾脏粘连将脾脏一并切除。1例年龄大(74岁)心功能不全而保守治疗,随访2a肿瘤由隆起性病变形成巨大溃疡。20例病理报告均为腺癌。结论:隐蔽区胃癌因其发病位置相对特殊,前后左右相互重迭或病变位于贲门后上方,不论钡剂造影及胃镜检查均易漏诊或病变范围不易确定,因此,如何掌握本病的检查技巧是提高本病检出率的重要环节。
