Epub 2020 Mar 5. Medical; Ways to Abbreviate 1 other way to abbreviate age-adjusted International Prognostic Index. The diagnosis of this lymphoma can be challenging because large amounts of background necrosis are present in the biopsies, which may be quite small. EBV is usually absent in lymphomas arising in immunocompetent individuals but may be expressed in immunosuppressed patients. Other antigens are heterogeneously expressed in diffuse large B-cell lymphoma, including CD10 (25% to 50%), BCL2 (50% to 60%) and BCL6 (40% to 90%). Three risk groups with different PFS and OS were identified by the sAAIPI: low risk (0 factors), 70% and 74%; intermediate risk (1 factor), 39% and 49%; and high risk (2 or 3 factors), 16% and 18% (P <.001 for both PFS and OS). EBV+ diffuse large B-cell lymphoma affects immunosuppressed patients and elderly nonimmunosuppressed patients. 2013 Sep;98(3):346-54. doi: 10.1007/s12185-013-1403-z.  |  Diffuse and interstitial patterns are most common, but nodular nonparatrabecular and occasionally paratrabecular involvement also may be seen.84 Flow cytometry and molecular genetic studies to assess clonality can increase the sensitivity of detection, and some studies have shown that patients with negative bone marrow histology but clonal B cells detected by PCR have inferior survival to those lacking a demonstrable B-cell clone.246 However, histologic diagnosis remains the gold standard for establishing bone marrow involvement. 2019 Jul 25;178(3):699-713.e19. Gene expression profiling of this lymphoma reveals a surprising similarity with classical Hodgkin lymphoma. This lymphoma presents with exclusive localization of vascular spaces and does not form a tissue mass. In contrast, the studies of Andersen et al.30 and Samaha et al.23 suggested that the IPI has no impact on the patients' survival. 6.14. 2002 May;49 Suppl 1:S13-20. The tumor cells are positive for CD138, dim to partial CD45+, and epithelial membrane antigen and may also have expression of CD4 but are negative for the pan B-cell markers CD19, CD20, CD22, and CD79, as well as pan T-cell markers CD2, CD3, CD5, and CD7. investigated the value of molecular remission as a prognostic factor in MCL patients following high-dose radiochemotherapy and autologous stem cell transplantation.33 Similar to follicular lymphoma, molecular remission was a strong prognostic factor predicting progression-free survival (PFS). Sheets of large B cells are unusual in reactive conditions and should raise strong concern for lymphoma. Choi MK, Kang ES, Kim DW, Ko YH, Seok H, Park JH, Pyo DH, Hoon Lim D, Kim SJ, Kim WS. Reduzierter Allgemeinzustand: ECOG-Performance Status > 2 bzw. At a median follow-up of 4 years, the PFS and OS are 28% and 34% by intention to treat and 39% and 45% for only those patients with chemosensitive disease. Because this is such an uncommon lymphoma, recurrent genetic abnormalities have not been identified, but they do demonstrate rearranged immunoglobulin genes. A recent study by Pott et al. The IPI score separates four prognostic groups based on the number of factors present: (0, 1: low-risk group; 2: low-intermediate-risk group; 3: high-intermediate-risk group; and 4, 5: high-risk group). As the name implies, these lymphomas are characteristically positive with ALK and the pattern of positivity is in a granular cytoplasmic pattern. This prognostic information was first gleaned from gene expression profiling studies, which suggested lymphomas with a germinal center phenotype had a better prognosis than those with an activated B-cell phenotype. A recent study has demonstrated greater than 30% of similarity of genes that were highly expressed in an MLBCL and classical Hodgkin lymphoma versus other diffuse large B-cell lymphomas. Immunophenotype, such as the presence or absence of c-myc and BCL-2 or BCL-6, may also influence choice of therapy. Such an early use was associated with a decrease of repeated hospitalizations and shorter length of stay in hospital in another study.36, Robert P. Hasserjian, in Extranodal Lymphomas, 2011.
