Whole-genome and transcriptome sequencing of primary cutaneous CD8+ aggressive epidermotropic cytotoxic T-cell lymphoma

ABSTRACT: Primary cutaneous CD8+ aggressive epidermotropic cytotoxic T-cell lymphoma (pcAECyTCL) is a rare variant of cutaneous T-cell lymphoma with an aggressive clinical course and a very poor prognosis. We subjected tumor biopsies from patients with pcAECyTCL to whole-genome sequencing and RNA-sequencing to investigate genomic alterations and deregulated gene expression in the disease.

Single-cell RNAseq profiling in a patient with discordant primary cutaneous B and T cell lymphoma reveals micromilieu-driven immune skewing

Project description:Background: Primary cutaneous lymphomas comprise a heterogeneous group of B and T cell malignancies which often show an indolent course, but can progress to aggressive disease in a subset of patients. Diagnosis is often delayed due to clinical and histopathological similarities with benign inflammatory conditions. Especially during early disease, cancer cells are present at relatively low percentages in comparison to the inflammatory infiltrate, an interplay that is currently only insufficiently understood. Objectives: To improve diagnostics and perform molecular characterization of a complex type of primary cutaneous lymphoma. Methods: Single-cell RNA sequencing (scRNA-seq) combined with T and B cell receptor sequencing. Results: We were able to diagnose a patient with concurrent mycosis fungoides (MF) and primary cutaneous follicle center lymphoma (PCFCL), appearing in mutually exclusive skin lesions. Profiling of tumor cells and the tissue microenvironment revealed a type-2 immune skewing in MF, most likely guided by the expanded clone that also harbored upregulation of numerous pro-oncogenic genes. By contrast, PCFCL lesions exhibited a more type-1 immune phenotype, consistent with its indolent behavior. Conclusions: These data not only illustrate the diagnostic potential of scRNA-seq, but also allow the characterization of specific clonal populations shaping the unique tissue microenvironment in clinically distinct types of lymphoma skin lesions.

The genomic landscape of primary cutaneous anaplastic large cell lymphoma (pcALCL)

Project description:Primary cutaneous anaplastic large cell lymphoma (pcALCL) is the second most common variant of cutaneous T-cell lymphoma. We subjected tumor biopsies from patients with pcALCL to whole-genome sequencing, whole-exome sequencing and RNA-sequencing to investigate genomic alterations and deregulated gene expression in the disease.

MicroRNA profiling of primary cutaneous large B-cell lymphomas

Project description:High-throughput sequencing of primary cutaneous follicle center lymphoma (PCFCL), primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL-LT) and in vitro activated peripheral blood B-cells. We performed high-throughput sequencing analysis on frozen tumor biopsies from 19 cases of PCFCL and PCLBCL-LT to establish microRNA profiles. Cluster analysis of the complete microRNome could not distinguish between the two subtypes, but 16 single microRNAs were found to be differentially expressed. Lymphoma miRNA profiles of were generated by deep sequencing, using Illumina Genome Analyzer II.

Gene Expression Profiles of cutaneous B-cell lymphoma

Project description:We studied gene expression profiles of 17 cutaneous B-cell lymphomas that were collected with 4-6 millimeter skin punch biopsies. We also included tissue from 2 cases of mycosis fungoides (MF), 3 normal skin biopsies and 3 tonsils to create a framework for further interpretation. A hierarchical cluster algorithm was applied for data analysis. Our results indicate that small amounts of skin tissue can be used successfully to perform microarray analysis and result in distinct gene expression patterns. Duplicate specimens clustered together demonstrating a reproducible technique. Within the cutaneous B-cell lymphoma specimens two specific B-cell differentiation stage signatures of germinal center B-cells and plasma cells could be identified. Primary cutaneous follicular and primary cutaneous diffuse large B-cell lymphomas had a germinal center B-cell signature while a subset of marginal zone lymphomas demonstrated a plasma cell signature. Primary and secondary follicular B-cell lymphoma of the skin were closely related, despite previously reported genetic and phenotypic differences. In contrast primary and secondary cutaneous diffuse large B-cell lymphoma were less related to each other. This pilot study allows a first glance into the complex and unique microenvironment of B-cell lymphomas of the skin and provides a basis for future studies, that may lead to the identification of potential histologic and prognostic markers as well as therapeutic targets.

Genomic Landscape of Cutaneous Diffuse Large B Cell Lymphoma

Project description:<p>Cutaneous diffuse large B cell lymphomas (DLBCL) are aggressive lymphomas with a poor prognosis. To elucidate their genetic bases, we performed whole exome capture and massively parallel sequencing on 19 tumor samples of diffuse large B cell lymphoma, leg type (DLBCL-LT) and 6 samples of secondary cutaneous diffuse large B cell lymphoma, not otherwise specified (DLBCL-NOS). Tumor specimens and their associated sequencing data were from multiple institutions, including Northwestern University (Chicago, IL), Massachusetts General Hospital (Boston, MA), and Medical University of Graz (Graz, Austria).</p>
