550:, to the CHOP regimen appears to have improved these results: in one study, patients receiving the R-CHOP regimen had a three-year overall survival rate of 75%. Since treatment of the variant form of nodular lymphocyte predominant Hodgkin lymphoma using different and less aggressive drug regimens achieves better results than the regimens used to treat THRLBCL, it is clinically important to distinguish the two diseases. 135:(i.e. microscopic appearances), genetic abnormalities, and apparent etiologies. Indeed, NLPHL can, in rare cases, progress into THRLBCL. Comapared to THRLBCL, however, these variant NLPHL cases are less aggressive, are more responsive to treatment, and have a better prognosis. Thus, THRLBCL and NLPHL may be biologically related diseases that represent opposite ends of a severity spectrum. 144:

Patients typically present with enlarged lymph nodes in the neck, arm pit, and groin areas but on further examination are found to have involvement of their spleen (31% of cases), liver (52% of cases), bone marrow (27% of cases) and lung/or (13%) as determined by finding enlarged spleens and/or livers on physical examination or
