“…The studies focused on NPC and the imaging techniques used for diagnosis ( n = 5) [ 28 , 33 , 35 , 37 , 39 ], splenic metastases from solid tumors ( n = 3) [ 3 , 5 , 31 ], experience of a single institution in NPC treatment ( n = 2) [ 30 , 34 ], use of serum markers in monitoring NPC systemic relapse ( n = 1) [ 29 ], and chemotherapy in NPC patients ( n = 1) [ 32 ]. Nine studies [ 3 , 28 , 29 , 32 – 35 , 38 , 39 ] were performed in Asian populations, three in Western countries [ 5 , 31 , 37 ], one in the Middle East [ 27 ], one in Africa [ 30 ], and one in India [ 36 ].
