Clinical Correlation of Bone Marrow Microvessel Density in Essential Thrombocythemia

Abstract: The aim of this study was to investigate the prognostic relevance of angiogenesis expressed as bone marrow microvessel density (MVD) in 40 patients with essential thrombocythemia (ET). Bone marrow MVD was visualized in paraffin tissue sections using immunohistochemical staining for CD34 protein. Increased MVD of bone marrow specimens was not significantly correlated with clinical (sex, age, microvascular disturbances, liver and spleen size, complications, treatment or no before biopsy), laboratory (peripheral … Show more

“…This indicates that angiogenesis is not involved, at least at diagnosis, in PV and ET. The scenario may change when patients with a long‐lasting PV or ET are considered, as suggested by Panteli et al (2005). Concerning different CMD, our study suggests that the evaluation of MVD may be an additional useful tool for pathologists to diagnose disease evolution and to discriminate between ET and PMF at the prefibrotic stage.…”

“…Its evaluation provides useful prognostic information in haematological malignancies, such as acute leukaemia, myelodysplastic syndromes (Aguayo et al , 2000; Keith et al , 2007) and multiple myeloma (Rajkumar et al , 2000; Pruneri et al , 2002). Of the CMDs, angiogenesis is the most evident in PMF (Mesa et al , 2000; Panteli et al , 2005). This study evaluated BM MVD in 115 patients with CMD and investigated its relationship with clinical, haematological and molecular features.…”

“…In contrast, cancer cell infiltration results in replacement of fatty marrow by cancer cells, increasing the cellular content of BM, with a focal, multifocal or diffuse distribution [43][44][45]. Angiogenesis, which facilitates malignancy perfusion, has been described in BM [46][47][48]. In certain specific malignancies, BM necrosis can occur, resulting in loss of myeloid tissue and marrow fat without trabecular destruction [43].…”

“…Only 10–20% of them harbor none of these three driver mutations ( 1 ) this group is referred to as having triple negative ET. Angiogenesis is increased in several types of cancer, including ET, where increased bone marrow angiogenesis is observed ( 2 ).…”
