Aggressive primary cutaneous B‐cell lymphomas show increased Angiopoietin‐2‐induced angiogenesis

Abstract: Primary cutaneous large B-cell lymphomas, leg type (PCLBCL/LT) are primary cutaneous B-cell lymphoma (PCBCL) with an intermediate prognosis. Therefore, antracycline-based polychemotherapy combined with rituximab has been recommended as first-line treatment. Yet, despite this regimen, the 5-year survival rate remains 50-66% only. Angiogenesis, the formation of a vascular network, is essential for the pathogenesis of nodal lymphomas. So far, no study has analysed angiogenesis and its key factors in PCLBCL/LT. Th… Show more

“…Whereas Bcl‐2 is strongly expressed in the majority of tumor cells in almost all cases of PCLBCL/LT and is therefore an easily identifiable and reproducible finding, the expression level of Bcl‐2 in PCLBCL/NOS varies, which renders its use as a discriminating factor challenging. Moreover, the clinicopathological features of PCLBCL/NOS are poorly defined as this subtype is unusual and very rarely appears in large studies of primary cutaneous B‐cell lymphomas . In addition, there are no recommendations for the management of PCBCL/NOS .…”

“…ANGPT2 staining was performed as described earlier (14). In brief, freshly-cut TMA sections were mounted on super frost glass plates and stained with anti-ANGPT2 antibody (Santa Cruz Biotechnology) using Ultraview universal HRP multimer detection kit (Ventana, USA).…”

“…Während die Expression von Bcl‐2 bei nahezu allen Fällen von PCLBCL/LT in der Mehrzahl der Tumorzellen stark ist und daher leicht und reproduzierbar festgestellt werden kann, variiert der Bcl‐2‐Expressionsgrad bei PCLBCL/NOS, weshalb seine Verwendung als Unterscheidungsfaktor schwierig ist. Darüber hinaus sind die klinisch‐pathologischen Eigenschaften des PCLBCL/NOS unzureichend definiert, da dieser Subtyp selten ist und nur sehr selten in umfangreichen Studien zum primär kutanen B‐Zell‐­Lymphom zu finden ist . Auch gibt es keine Empfehlungen für die Behandlung des PCLBCL/NOS .…”
