目的:比较PET/CT与常规检查(CWU)评估鼻咽癌远处转移的诊断效能。方法:将514例鼻咽癌患者分为PET/CT及CWU两组,CWU组采用胸片、B超及全身骨扫描评估远处转移病灶,分析对比两组检查结果。结果:PET/CT组216例中报告远处转移32例,均证实报告准确;CWU组298例中报告可疑转移患者42例,其中28例证实为远处转移,另有3例远处转移未检出。两组检查敏感性分别为100.0%(32/32)和90.3%(28/31),特异性分别为100.0%(184/184)和94.8%(253/267),差异均无统计学意义。PET/CT组N2~3分期远处转移率、多发转移及多器官转移患者比例均高于CWU组(P<0.01或0.05)。结论:PET/CT检查稍优于CWU,但临床实践中CWU仍是价廉、实用的方法。
Objective: To compare the diagnostic efficacy of PET / CT and routine examination (CWU) in the assessment of distant metastasis of nasopharyngeal carcinoma. Methods: 514 patients with nasopharyngeal carcinoma were divided into two groups: PET / CT and CWU. The CWU group was evaluated by X-ray, B-mode ultrasonography and whole-body bone scan. The results of the two groups were analyzed and compared. Results: In the PET / CT group, 32 cases of distant metastasis were reported in 216 cases, all of which confirmed the accurate report. Of the 298 cases in the CWU group, 42 cases were suspiciously transferred, of which 28 cases were confirmed distant metastasis and 3 cases were distant metastasis Check out. The sensitivity of the two groups was 100.0% (32/32) and 90.3% (28/31) respectively, with a specificity of 100.0% (184/184) and 94.8% (253/267), respectively, with no significant difference. The rates of distant metastasis, multiple metastasis and multiple organ metastasis in patients with PET / CT at N2 ~ 3 stage were higher than those in CWU group (P <0.01 or 0.05). Conclusion: PET / CT examination is slightly better than CWU, but CWU is still a cheap and practical method in clinical practice.
