Key result
PET-CT demonstrates high sensitivity and specificity in detecting bone marrow involvement in newly diagnosed DLBCL, making the routine use of bone marrow biopsy debatable except in specific scenarios.
Why the study?
Advancements in PET-CT have improved detection of bone marrow involvement in DLBCL, making the need for standard bone marrow biopsy debatable.
Does PET-CT improve the detection of bone marrow involvement compared to bone marrow biopsy in adult patients newly diagnosed with DLBCL?
Does PET-CT improve the detection of bone marrow involvement compared to bone marrow biopsy in adult patients newly diagnosed with DLBCL?
PET-CT demonstrates superior sensitivity and accuracy compared to bone marrow biopsy for detecting concordant bone marrow involvement in newly diagnosed DLBCL, supporting its role as a primary staging modality.
BM biopsy remains standard for DLBCL staging; leaves open whether PET imaging can reliably replace it.
Diffuse large B cell lymphoma (DLBCL) is one of the most prevalent subtypes of non-Hodgkin lymphoma (NHL) and is known for commonly infiltrating extra-nodal sites. The involvement of the bone marrow by lymphoma cells significantly impacts the staging, treatment, and prognosis among the extra-nodal sites in DLBCL. Bone marrow biopsy has been considered the standard diagnostic procedure for detecting bone marrow involvement. However, advancements in imaging techniques, such as positron emission tomography-computed tomography (PET-CT), have shown an improved ability to detect bone marrow involvement, making the need for bone marrow biopsy debatable. This review aims to emphasize the importance of bone marrow evaluation in adult patients newly diagnosed with DLBCL and suggest an optimal diagnostic approach to identify bone marrow involvement in these patients.

Alyamany et al. (2024) conducted a review in Diffuse large B cell lymphoma (DLBCL). PET-CT vs. Bone marrow biopsy was evaluated on Detection of bone marrow involvement. PET-CT demonstrates high sensitivity and specificity in detecting bone marrow involvement in newly diagnosed DLBCL, making the routine use of bone marrow biopsy debatable except in specific scenarios.
