Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with histologically confirmed transformation of SMZL and available diagnostic tumor material and baseline and follow-up clinical annotations are eligible.

Probably not a fit

Patients without available tumor tissue or with incomplete baseline or follow-up records are unlikely to contribute usable data and thus may not benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a retrospective observational project that collects existing coded tumor material (frozen or FFPE) and linked clinical data from institutional biobanks and medical records after ethical approval. Each patient will receive a unique ID code and annotated baseline and follow-up clinical features will be entered into an electronic case report form with quality checks. Molecular profiling will be performed on available diagnostic and transformation-time tumor samples to characterize genetic complexity alongside clinical course and treatments. The combined molecular and clinical dataset aims to define patterns associated with histological transformation and outcomes in t-SMZL.

Why it matters

Potential benefit: If successful, the work could identify genetic drivers and clinical markers that help clinicians choose more specific and effective treatments for patients with transformed SMZL.

How similar studies have gone: Genomic and clinical profiling has produced useful insights in other lymphoma subtypes, but comprehensive molecular data specifically for transformed SMZL are limited, so this approach is relatively novel for this disease.

Inclusion Criteria:

1. Adults aged 18 years or older, regardless of the gender;
2. Diagnosis of HT of SMZL (both at baseline, co-occurring with diagnosis of SMZL, or during the natural history of the disease);
3. Availability of diagnostic tumor material (either frozen or FFPE) from spleen, lymph node, extra nodal site, peripheral blood or bone marrow collected at the time of histological transformation. Tumor material (either frozen or FFPE), from spleen, peripheral blood or bone marrow, collected at the time of SMZL diagnosis will be also collected, if available;
4. Availability of the baseline and follow-up annotations.

Exclusion Criteria:

* None
