By type of lymphoma, significant differences in proportion of patients tested by hospital were observed among patients with Hodgkin’s lymphoma (p = 0.007), DLBCL (p = 0.037), mantle cell lymphoma (p = 0.029), follicular lymphoma (p = 0.001) and marginal zone or mucosa-associated lymphoid tissue lymphoma (p<0.001), but not among patients with T-cell lymphoma (p = 0.364), Burkitt lymphoma (p = 0.891), LPL (p = 0.504), and other NHL types (p = 0.095). This evidence concerns the gene LPL and mantle cell lymphoma.
