“…In the previously reported families, NPC was sometimes associated with other, potentially EBVrelated malignancies (not shown in Table I), such as Burkitt's lymphoma, lymphoblastic ''sarcoma'', acute lymphoblastic leukemia and non-Hodgkin's lymphoma [4,20]. Moreover, other non-EBV-related malignancies were also detected, such as multiple myeloma, acute non-lymphocytic leukemia, brain tumor, gastric and colonic adenocarcinoma, malignant melanoma and carcinoma of the tongue and breast [4,5,20,21,24], reflecting the possible genetic susceptibility of these families to tumor development.…”
