Project description:This is a genomic analysis of breast cancer metastasis using array based CGH and is part of a large study investigating the patterns and evolution of metastases from breast cancer using autopsy material accumulated over the last 50 years from a single institution. The samples used in the genomic profiling comprise the primary breast tumour and multiple matched metastases from each patient. The data demonstrate both the clonal nature of metastatic progression and the role of clonal evolution during progression. This study comprises six patients who died of metastatic breast cancer. For some patients the breast primary tumour and lymph node metastasis was obtained from previous surgical excision, otherwise material was obtained from a resulting autopsy. Each patient set of samples involves the primary breast tumour and multiple metastases, including from lung, liver, lymph node, adrenal gland, brain etc. DNA was extracted from formalin fixed paraffin embedded (FFPE) tissue blocks and analysed for DNA copy number alterations using an Agilent aCGH platform.
Project description:We performed a quantitative proteome comparison on formalin-fixed paraffin embedded (FFPE) tissue of metastasized and non-metastasized primary prostate cancer (PCa) and on recurrent lymph node metastases. Comparing these three sample groups, we aimed to identify proteins, that might potentially promote/supress tumor progression or metastasis formation. Proteins were quantified label-free. Proteins with interesting biological functions were followed-up by immunohistochemistry.
Project description:To investigate the biological differences between EBV-/HIV-, EBV+/HIV- and EBV+/HIV+ classic Hodgkin lymphoma, we performed RNA sequencing of 19 pre-treatment formalin-fixed paraffin-embedded (FFPE) whole lymph node biopsies of cHL.
Project description:To investigate the biological differences between HIV-, HIV+/ART-experienced and HIV+/ART-naive diffuse large B-cell lymphoma, we performed RNA sequencing of 70 pre-treatment formalin-fixed paraffin-embedded (FFPE) whole lymph node biopsies of diffuse large B-cell lymphoma.

Project description:The aim of this study was to evaluate whether microRNA profiles of grade 1 – 2 or 3 endometrioid adenocarcinomas can be related to nodal status and used as a tool to adapt surgical staging in early-stage EC. MicroRNA expression were assessed in twelve formalin-fixed paraffin-embedded (FFPE) EC primary tumors with positive lymph node and in 36 FFPE EC primary tumors with negative lymph node, matched for grade, stage and lymphovascular space involvement status.
