Prognostic relevance of microenvironmental factors CD163 and CD8 combined with EZH2 and chromosome 18 gain in a validation cohort of follicular lymphoma patients of the Lunenburg Lymphoma Biomarker Consortium

Background: In follicular lymphoma (FL), studies addressing the prognostic value of microenvironment-related immunohistochemical (IHC) markers and tumor cell-related genetic markers have yielded conflicting results, precluding implementation in practice. Therefore, the Lunenburg Lymphoma Biomarker Consortium (LLBC) performed a validation study for published markers. Methods: To maximize sensitivity, an end-of-spectrum design was applied for 122 uniformly immunochemotherapy-treated FL patients retrieved from international trials and registries; early failure (EF): progression or lymphoma-related death <2 years versus long remission: response duration of >5 years. IHC staining for T-cells and macrophages was performed on tissue microarrays from initial biopsy and scored with a validated computer-assisted protocol. Shallow whole-genome and deep targeted sequencing was performed on the same samples. Results: 96/122 cases with complete molecular and immunohistochemical data were included in the analysis. EZH2 wild-type (p=0.006), gain of chromosome 18 (p=0.002), low percentages of CD8+ cells (p=0.011) and CD163+ areas (p=0.038) were associated with EF. No significant differences in other markers were observed, thereby refuting previous claims on their prognostic significance. Conclusion: Using an optimized study design, this LLBC study validates wild-type EZH2 status, gain of chromosome 18, low percentages of CD8+ cells and CD163+ area as predictors of EF to immunochemotherapy in FL.

Data originating from patient samples

The Amsterdam UMC, tumor genome analysis core, allows access to published datasets upon written application and signature of a Data Access Agreement (DAA). In addition, applications to clinical datasets require approval by a Data Access Committee (DAC), who assess whether the proposed work is allowed given patient consent, as well as the scientific purpose. To aid this process we ask you to provide the information below. Requests will be prioritised according to novelty of the research question. Applications with insufficient detail on objectives, justification, and methods/planned analyses are unlikely to be accepted. 1.Reference number for the dataset 2.Full legal name and address of university/institution 3.Name(s) of the Principle Investigator who will use the data: 4.Name(s) and job title(s) of any other investigators who will use the data: 5.Please provide a minimum of one reference to a publication that can be found on PubMed and where the Principle Investigator is an author: 6.How will the data be stored and where will it be stored? 7.What is the proposed study title and what are the objectives and outcomes of the study in which the data will be used 8.Please provide a brief justification or rationale for the proposed study (max 250 words) 9.Please provide a brief description of planned data analyses (max 250 words): 10.Will the results arising from use of the data be used for the creation of products for sale or for any commercial purpose?

Studies are experimental investigations of a particular phenomenon, e.g., case-control studies on a particular trait or cancer research projects reporting matching cancer normal genomes from patients.
