Diffuse large B-cell non-Hodgkin's lymphoma in Gaucher disease

Area of Science:

• Hematology
• Oncology
• Genetics

Background:

• Gaucher disease type 1 (GD1) is a common lysosomal storage disease with varied presentation.
• GD1 patients exhibit an elevated risk for certain malignancies, including non-Hodgkin's lymphoma (NHL) and multiple myeloma.
• The Ashkenazi Jewish population has a higher prevalence of GD1.

Purpose of the Study:

• To describe cases of GD1 patients diagnosed with diffuse large B-cell lymphoma (DLBCL).
• To discuss the relationship between GD1 and NHL.
• To review recent findings on lyso-GL1 and its role in NHL and multiple myeloma development.

Main Methods:

• Case report of two Ashkenazi Jewish males with GD1 and DLBCL.
• Review of literature and meta-analysis of GD1 and NHL.
• Discussion of enzyme replacement therapy (ERT) and other treatments.

Main Results:

• One patient developed DLBCL after starting ERT for GD1, relapsed, and succumbed to complications post-transplant.
• Another patient diagnosed with DLBCL at age 22, later treated for GD1, remains in lymphoma remission.
• The study will elaborate on a meta-analysis of GD1 and NHL incidence.

Conclusions:

• GD1 is associated with an increased risk of NHL and multiple myeloma.
• Understanding this association is crucial for patient management and risk stratification.
• Further research into lyso-GL1 may elucidate mechanisms linking GD1 to lymphomagenesis.
