Abstract:
BACKGROUND:A meta-analysis was conducted to evaluate the accuracy of MRI, CT and FDG PET/CT in TNM stage of nasopharyngeal carcinoma patients (NPC). METHODS:Through a search of studies from 1996 to April 2015, pooled estimated sensitivity, specificity, pooled diagnostic odds ratio (DOR), summary receiver operating characteristic (SROC) curves and Q*-index were calculated. RESULTS:Totally 23 studies were included for analysis. In T stage, the pooled sensitivity, specificity, DOR and SROC of MRI were 0.95 (95% CI 0.93-0.97), 0.76 (95% CI 0.71-0.80), 86.85 (16.36-461.06) and 0.9213 (SE 0.0372) respectively. The pooled sensitivity, specificity, DOR and SROC of CT were 0.84 (95% CI 0.79 to 0.88), 0.80 (95% CI 0.71 to 0.88), 6.32 (1.17 to 34.02) and 0.7215 (SE 0.054) respectively. The pooled sensitivity, specificity, DOR and SROC of FDG PET/CT were 0.85 (95% CI 0.76 to 0.91), 0.91 (95% CI 0.84 to 0.96) and 0.8673 (SE 0.0311). In N stage, the pooled sensitivity, specificity, DOR and SROC of MRI were 0.88 (95% CI 0.85-0.90), 0.95 (95% CI 0.93-0.97), 93.68 (23.21-379.69) and 0.9153 (SE 0.099) respectively. The pooled sensitivity, specificity, DOR and SROC of CT were 0.92 (95% CI 0.88-0.95), 0.93 (0.76-0.99), 93.81 (22.39-393.03) and 0.8872 (SE 0.0520) respectively. The pooled sensitivity, specificity, DOR and SROC of FDG PET/CT were 0.88 (95% CI 0.85-0.90), 0.95 (95% CI 0.93-0.97), 93.88 (23.21-379.69) and 0.9153 (SE 0.0299) respectively. In M stage, the pooled sensitivity and specificity of MRI were 0.53 (95% CI 0.35-0.70) and 0.99 (95% 0.95-1.00). The pooled sensitivity and specificity of CT were 0.80 (95% CI 0.44-0.97) and 0.93 (95% CI 0.86-0.97) respectively. The pooled sensitivity, specificity and SROC of FDG PET/CT were 0.82 (95% 0.74-0.88), 0.98 (95% CI 0.96-0.99) and 0.9002 (SE 0.075) respectively. CONCLUSION:The analysis suggested that MRI had good accuracy in diagnosis of T stage. Whereas CT is currently a good performance in diagnosis of N stage, FDG PET/CT shows good accuracy in diagnosis of M stage.
