Brief Title
Genomic and Proteomic Study of Richter Syndrome (CGPSR)
Protocol ID
NCT03619512
Lead Sponsor
Central Hospital, Nancy, France
Brief Summary
Biological study on Richter Syndrome (RS), an agressive lymphoma that arises from Chronic
Lymphocytice Leukemia (CLL). RS presents with the same histological aspect as primitive
Diffuse Large B-Cell Lymphoma (DLBCL), but is associated with a poor prognosis, due to
chemorefractoriness.
This study aims at understanding the biological determinants of chemotherapy resistance
in Richter Syndrome.
Detailed Description
With the help of the French National Research Group on CLL (FILO / French Innovative
Leukemia Organization), the investigators are currently gathering fresh frozen cell
pellets at CLL stage, and lymph node biopsies at Richter stage. The investigators also
gathered lymph node biopsies from DLBCL, as a reference group.
The investigators will perform genomic and proteomic comparative studies between CLL and
Richter, as well as between Richter and primitive DLBCL, to understand the biological
determinants of clonal evolution and chemorefractoriness of Richter Syndrom.

Eligibility Criteria
Inclusion Criteria:
- Diagnosis of a Diffuse Large B-Cell Lymphoma arising in the context of a Chronic
Lymphocytic Leukemia (group 1) or diagnosis of a primitive Diffuse Large B-Cell
Lymphoma (group 2), or diagnosis of a Diffuse Large B-Cell Lymphoma arising in a
context of small cells lymphoma, excluding CLL (group 3), or benefit from a
diagnostic lymph node biopsy that did not reveal any tumor involvment (primitive or
metastatic) (group 4).
- Patients must benefit from a lymph node biopsy at diagnosis.
- Patients must be followed by a FILO (French Innovative Leukemia Organization) member
- Histology of Diffuse Large B-Cell Lymphoma or Hodgkin histology.
- Suitable clinical data available.
- Samples must meet the following requirement :RIN (RNA Integrity Number) > 5 et DIN
(DNA Integrity Number) > 6.5.
Exclusion Criteria:
• Samples that do not meet the inclusion criteria (insufficient clinical data, analysis
impossible due to insufficient sample quality).
