Abstract
Background
In order to study the CXCR4 expression with [68Ga]pentixafor PET in different types of non-Hodgkin lymphoma, we performed a retrospective study to describe the [68Ga]pentixafor PET/CT imaging in a spectrum of lymphomas and to compare it with [18F]FDG PET/CT.
Results
Twenty-seven patients with newly diagnosed non-Hodgkin lymphoma were recruited retrospectively. [68Ga]pentixafor PET showed increased radioactivity in lymphoplasmacytic lymphoma (n = 8), marginal zone lymphoma (n = 4), diffuse large B cell lymphoma (n = 3), follicular lymphoma (n = 2), mantle cell lymphoma (n = 1), unclassified indolent B cell lymphoma (n = 3), and enteropathy associated T cell lymphoma (n = 3). However, peripheral T cell lymphoma, not otherwise specified (n = 1), and NK/T cell lymphoma (n = 2) were not avid for [68Ga]pentixafor. In comparison to [18F]FDG PET, [68Ga]pentixafor PET demonstrated more extensive disease and higher radioactivity in lymphoplasmacytic lymphoma and marginal zone lymphoma.
Conclusion
CXCR4 expression varies in different types of non-Hodgkin lymphoma. Overexpression of CXCR4 was detected with [68Ga]pentixafor PET/CT in lymphoplasmacytic lymphoma, marginal zone lymphoma, diffuse large B cell lymphoma, follicular lymphoma, mantle cell lymphoma, unclassified indolent B cell lymphoma, and enteropathy associated T cell lymphoma. The uptake of [68Ga]pentixafor was higher than [18F]FDG in lymphoplasmacytic lymphoma and marginal zone lymphoma.
