Select gastric DLBCLs (N?=?6) and MALTs (N?=?13) were further examined for API2-MALT1 and IGH translocations, and P16 and P53 protein expression.     ///    "Gastric MALTs showed frequent API2-MALT1 (38%) but not IGH translocations (0%), and the DLBCLs showed neither translocation. "    ///    "In addition, API2-MALT1, P16 and P53 abnormalities occurred frequently in gastric lymphomas from this North American population. "
