Genetic clues could sharpen lymphoma diagnosis
NCT ID NCT07181785
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study examined genetic changes in 555 patients with aggressive B-cell lymphomas, such as diffuse large B-cell lymphoma. Researchers used a technique called FISH to look for specific gene rearrangements. The goal was to see if these genetic markers could help classify tumors more accurately according to the 2017 WHO system, which might eventually guide better treatment decisions for high-risk patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better classification of aggressive lymphomas, helping doctors choose the most effective treatments for each patient.
- What could go wrong
- This is a retrospective study, meaning it looks back at past data. It cannot prove that a new classification will improve outcomes, and results may not apply to all patients.

* Histologically-confirmed diagnosis of LBCL (i.e., DLBCL, HGBCL, unclassifiable B-cell lymphoma with features intermediate between DLBCL and BL), or aggressive B-cell lymphomas with blastoid morphology (excluding blastoid variant of mantle cell lymphoma and lymphoblastic lymphoma) * Histopathological diagnosis performed between 2000 and 2019. * HIV sero-negativity * Age ≥18 * Treatment with R-CHOP or other intensified polychemotherapy regimen * Availability of adequate histopathological samples at diagnosis for FISH analysis * Availability of clinical records and outcomes data Exclusion criteria • Histologic diagnosis other than DLBCL or unclassifiable B-cell lymphoma with features intermediate between DLBCL and BL
