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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Richter Syndrom at diagnosis | patients diagnosed with Richter Syndrom, for whom a suitable lymph node biopsy at diagnosis is available. |
| |
| Primitive Diffuse Large B-Cell Lymphoma | patients diagnosed with a primitive Large B-Cell Lymphoma, for whom a suitable lymph node biopsy at diagnosis is available. |
| |
| Other secundary Diffuse Large B-Cell Lymphoma | patients diagnosed with a secundary Large B-Cell Lymphoma (different from Richter Syndrom), for whom a suitable lymph node biopsy at diagnosis is available. |
| |
| Control group with no tumor involvment of lymph nodes | patients for whom a diagnostic lymph node biopsy has been performed, which did not conclude to any tumoral lymph node involvment. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Whole exome sequencing. | Genetic | Retrospective biological exploration of the samples, including tumoral DNA exploration. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Whole exome sequencing data using next generation sequencing method | Comparison between the DNA sequences from Richter syndrome samples and DNA sequences from primitive DLBCL samples to identify a set of mutations that are specific to Richter syndrome. For each position, the result is "mutated" or "unmutated". | 3 years |
| RNA sequencing data using next generation sequencing method | Measurment of gene expression for all genes. Comparison of these expression levels between Richter samples, primitive DLBCL samples and normal lymph nodes to identifiy a set of genes which expression levels are different in Richter samples compared primitive DLBCL and normal lymph nodes. Gene expression is a quatitative value. This set of genes forms a specific "transcriptomic signature" of Richter syndrome. | 3 years |
| Proteomic analysis using mass spectrometry | Mass spectrometry allows identification and measurment of the expression level of the 5,000 most expressed proteins in a sample. The investigators want to compare the protein expression levels between Richter samples, primitive DLBCL samples and normal lymph nodes to identifiy a set of proteins that are highly expressed in Richter samples (but not in primitive DLBCL or normal lymph nodes). This set of proteins forms a specific "proteomic signature" of Richter. Protein expression is a quatitative value expressed as an absolute number of copies in a cell. | 3 years |
