Clinical features and 18F-FDG PET/CT for distinguishing of malignant lymphoma from inflammatory lymphadenopathy in HIV-infected patients

Table 2 The ROC curves and cut-off value of different parameters in HIV-infected patients with malignant lymphoma and those with inflammatory lymphadenopathy

parameter	Areas under the ROC curve	P value	Data of cut-off value
parameter	Areas under the ROC curve	P value	Cut-off value	Sensitivity	Specificity
SUR_max	0.888	0.000	3.1	68.2%	91.9%
SUV_LN	0.815	0.000	8.0	63.6%	89.2%
SUV_Marrow	0.611	0.156	NA*	NA	NA
SUV_Liver	0.567	0.393	NA	NA	NA
Number of lymph node involved areas	0.692	0.014	5	62.2%	72.7%
Maximum diameter of lymph nodes	0.768	0.001	3.6	64.9%	86.4%

ROC: receiver operating characteristic curve; HIV: human immunodeficiency virus; SUV: standard uptake value; SUVLN: the maximum of standard uptake value of only lymph nodes; SUR_max: the most FDG-avid lesion-to-liver SUV_max ratio. SUV_Liver: SUV_max of liver; SUV_Spleen: SUV_max of spleen; SUV_Marrow: SUV_max of bone marrow
NA*: no statistical significance and cut-off value were found
