Core Tip

Core tip: In 2003, a new primer system was successfully developed and standardized for the detection of clonally rearranged immunoglobulin (Ig) and T-cell receptor (TCR) genes. This study was a prospective analysis of Ig heavy chain (IgH) and TCR-γ gene rearrangements using the new primer system and endoscopic biopsy specimens from patients with suspected primary gastric lymphoma (PGL). Our study revealed that the detection of monoclonal IgH gene rearrangements is useful for the diagnosis of PGL and for differentiating between PGL and gastric linitis plastica. Monoclonal IgH gene rearrangements may be associated with PGL staging. The sensitivity and the specificity of IgH gene rearrangements for the diagnosis of PGL were 66.7% and 96.4%, respectively.
