Study population: 99 LN (lymph nodes) and 65 PB (peripheral blood) samples obtained from patients diagnosed with LPDs in our institution between 2012 and 2014 were evaluated for CD180 expression by FCM. The diagnosis were made according to the WHO 2008 classification, including clinical and morphological analysis, immunophenotyping, and conventional and molecular cytogenetics (and/or fluorescent in situ hybridization). The diagnoses were follicular lymphoma (FL) (LN, n=44; PB, n=15), small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL)/CLL (LN, n=26; PB, n=21), MCL (LN, n=13; PB,n=17), and MZL (LN, n=16; PB, n=12). All PB samples presented circulating neoplastic B-cells, and in several cases, the diagnosis was made at the same time in LN and PB FL, n=4; SLL/CLL, n=18; MCL, n=5. MZL, n=6.
Who may be able to join
- Samples from patients with:
- LF: Follicular lymphoma
- MCL: Mantle cell lymphoma
- CLL/SLL: chronic lymphocytic leukemia/small lymphocytic leukemia
- MZL : splenic marginal zone
- Clt :control B-cells
Who cannot join
- Patient <18 years old
About this study
Official title: CD180 Overexpression in Follicular Lymphoma Is Restricted to the Lymph Node Compartment
Background:Altered Toll-like receptor (TLR) expression levels and/or mutations in its signaling pathway (such as MyD88 mutation) contribute to the pathogenesis of lymphoproliferative disorders (LPD). CD180 is an orphan member of the TLR family that modulates the signaling of several TLRs, but only limited studies have evaluated its expression by flow cytometry (FCM) in LPD.
Methods: Using a multiparameter FCM approach, biologists have assessed CD180 mean fluorescence intensity (MFI) in lymph nodes (LNs) and peripheral blood (PB) samples obtained from patients with follicular lymphoma (FL; LN/PB, n=44/n=15), chronic lymphocytic leukemia (CLL, n=26/n=21), mantle cell lymphoma (MCL, n=13/n=17), and marginal zone lymphoma (MZL, n=16/n=12). Specimens from non-tumoral PB and LN (n=8/n=12) were used as controls.

What is being measured
The primary outcome is the main question the study is designed to answer.
Immunophenotype Analysis by Flow Cytometry of lymph nodes samples at inclusion
Using a multiparameter FCM approach, biologists assessed the CD180 expression by our routine antigen panel in LN suspensions as well as in PB samples. Samples were analyzed on a BD FACSCanto II cytometer (BD FACS DIVA software; Becton Dickinson, San Jose, CA).
Measured: At inclusion, day 0.
Immunophenotype Analysis by Flow Cytometry of peripheral blood samples at inclusion
Using a multiparameter FCM approach, biologists assessed the CD180 expression by our routine antigen panel in LN suspensions as well as in PB samples. Samples were analyzed on a BD FACSCanto II cytometer (BD FACS DIVA software; Becton Dickinson, San Jose, CA).
Measured: At inclusion, day 0.

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02978898, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Dec 2016; AzTrials last refreshed its copy on 7 Nov 2026.
