Revisiting Circulating Extracellular Matrix Fragments as Disease Markers in Myelofibrosis and Related Neoplasms. Cancers (Basel) 2023; 15:4323. [PMID: 37686599 PMCID: PMC10486581 DOI: 10.3390/cancers15174323] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 08/04/2023] [Accepted: 08/07/2023] [Indexed: 09/10/2023] Open
Abstract
Philadelphia chromosome-negative chronic myeloproliferative neoplasms (MPNs) arise due to acquired somatic driver mutations in stem cells and develop over 10-30 years from the earliest cancer stages (essential thrombocythemia, polycythemia vera) towards the advanced myelofibrosis stage with bone marrow failure. The JAK2V617F mutation is the most prevalent driver mutation. Chronic inflammation is considered to be a major pathogenetic player, both as a trigger of MPN development and as a driver of disease progression. Chronic inflammation in MPNs is characterized by persistent connective tissue remodeling, which leads to organ dysfunction and ultimately, organ failure, due to excessive accumulation of extracellular matrix (ECM). Considering that MPNs are acquired clonal stem cell diseases developing in an inflammatory microenvironment in which the hematopoietic cell populations are progressively replaced by stromal proliferation-"a wound that never heals"-we herein aim to provide a comprehensive review of previous promising research in the field of circulating ECM fragments in the diagnosis, treatment and monitoring of MPNs. We address the rationales and highlight new perspectives for the use of circulating ECM protein fragments as biologically plausible, noninvasive disease markers in the management of MPNs.

Abstract
Myelofibrosis is an enigmatic myeloproliferative neoplasm, despite noteworthy strides in understanding its genetic underpinnings. Driver mutations involving JAK2, CALR or MPL in 90% of patients mediate constitutive JAK-STAT signaling which, in concert with epigenetic alterations (ASXL1, DNMT3A, SRSF2, EZH2, IDH1/2 mutations), play a fundamental role in disease pathogenesis. Aberrant immature megakaryocytes are a quintessential feature, exhibiting reduced GATA1 protein expression and secreting a plethora of pro-inflammatory cytokines (IL-1 ß, TGF-ß), growth factors (b-FGF, PDGF, VEGF) in addition to extra cellular matrix components (fibronectin, laminin, collagens). The ensuing disrupted interactions amongst the megakaryocytes, osteoblasts, endothelium, stromal cells and myofibroblasts within the bone marrow culminate in the development of fibrosis and osteosclerosis. Presently, prognostic assessment tools for primary myelofibrosis (PMF) are centered on genetics, with incorporation of cytogenetic and molecular information into the mutation-enhanced (MIPSS 70-plus version 2.0) and genetically-inspired (GIPSS) prognostic scoring systems. Both models illustrate substantial clinical heterogeneity in PMF and serve as the crux for risk-adapted therapeutic decisions. A major challenge remains the dearth of disease-modifying drugs, whereas allogeneic transplant offers the chance of long-term remission for some patients. Our review serves to synopsise current appreciation of the pathogenesis of myelofibrosis together with emerging management strategies.

Validation of the IPSET score for thrombosis in patients with prefibrotic myelofibrosis. Blood Cancer J 2020; 10:21. [PMID: 32098944 PMCID: PMC7042364 DOI: 10.1038/s41408-020-0289-2] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Revised: 12/12/2019] [Accepted: 01/13/2020] [Indexed: 11/09/2022] Open
Abstract
Pre-fibrotic myelofibrosis (pre-PMF) and essential thrombocythemia (ET) are characterized by similarly increased rate of thrombotic events, but no study specifically analyzed risk factors for thrombosis in pre-PMF. In a multicenter cohort of 382 pre-PMF patients collected in this study, the rate of arterial and venous thrombosis after diagnosis was 1.0 and 0.95% patients/year. Factors significantly associated with arterial thrombosis were age, leukocytosis, generic cardiovascular risk factors, JAK2V617F and high molecular risk mutations, while only history of previous thrombosis, particularly prior venous thrombosis, was predictive of venous events. The risk of total thromboses was accurately predicted by the the international prognostic score for thrombosis in essential thrombocythemia (IPSET) score, originally developed for ET, and corresponded to 0.67, 2.05, and 2.95% patients/year in the low-, intermediate-, and high-risk categories. IPSET was superior to both the conventional 2-tiered score and the revised IPSET in this cohort of pre-PMF patients. We conclude that IPSET score can be conveniently used for thrombosis risk stratification in patients with pre-PMF and might represent the basis for individualized management aimed at reducing the increased risk of major cardiovascular events. Further refinement of the IPSET score in pre-PMF might be pursued by additional, prospective studies evaluating the inclusion of leukocytosis and/or adverse mutational profile as novel variables.
