Individualized patient care in nodular lymphocyte-predominant Hodgkin lymphoma.

Abstract

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare lymphoma that has traditionally been considered a subgroup of Hodgkin lymphoma. However, morphology, surface marker expression, genetics, and clinical course are different from classic Hodgkin lymphoma. While most patients experience indolent disease with slow progression, some patients can also have more aggressive disease. Nevertheless, outcomes are excellent, and excess mortality due to NLPHL is at most very low. The treatment of newly diagnosed NLPHL has historically mirrored that of classic Hodgkin lymphoma. However, evidence for deviations from that approach has emerged over time and is discussed herein. Less evidence is available for the optimal management of relapsed patients. So-called variant histology has recently emerged as a biological risk factor, providing at least a partial explanation for the observed heterogeneity of NLPHL. Considering variant histology together with other risk factors and careful observation of the clinical course of the disease in each patient can help to assess individual disease aggressiveness. Also important in this mostly indolent disease are the preferences of the patient and host factors, such as individual susceptibility to specific treatment side effects. Considering all this together can guide individualized treatment recommendations, which are paramount in this rare disease.
