Improving disease understanding and outcome prediction in nodal marginal zone lymphoma

Integrated Molecular and Clinical Profiling to Improve Disease Characterization and Outcome Prediction in Nodal Marginal Zone Lymphoma

Observational International Extranodal Lymphoma Study Group (IELSG) · NCT05700149

This study is trying to better understand nodal marginal zone lymphoma by collecting and analyzing patient data and tumor samples from people diagnosed with the disease since 2000.

What this trial studies

This international observational cohort study aims to enhance the molecular classification of nodal marginal zone lymphoma (NMZL) by retrospectively collecting coded tumor biological material and health-related patient data from institutional biobanks and medical records. Patients diagnosed with NMZL since January 1, 2000, will be enrolled, and their data will be systematically recorded and analyzed to identify key clinical and biological features. The study will utilize a unique identification code for each patient to ensure data integrity and confidentiality. Follow-up data will also be collected to monitor disease progression and treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have been diagnosed with NMZL and have available tumor material collected when treatment-naïve.

Not a fit: Patients with nodal spread of clinically occult extranodal marginal zone lymphoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved disease characterization and more accurate outcome predictions for patients with NMZL.

How similar studies have performed: Other studies have shown success in utilizing molecular profiling to improve disease understanding in various lymphomas, indicating a promising approach for this study.

Inclusion Criteria:

1. Male or female adults 18 years or older
2. Diagnosis of NMZL on lymph node histology after Jan 1st, 2000
3. Availability of tumor material from lymph node (either frozen or FFPE) collected when the patient was treatment naïve
