Only in HL was co-expression of other SSTR receptors common while few cases of PTCL were positive for SSTR3 and to our surprise all 9 cases of MALT were negative for both SSTR and CXCR4 and similarly the majority of MCLs were receptor negative. This evidence concerns the gene CXCR4 and mature T-cell and NK-cell non-Hodgkin lymphoma.
