The epidermal growth factor receptor (EGFR) is highly expressed in gastric cancer indicating its suitability as a target for receptor tyrosine kinase (RTK) inhibitors. In the current study we explored the role of EGFR and its potential use as a therapeutic target in gastric cancer. First we analyzed 66 gastric cancer samples of Asian and Caucasian patients(More)
The concomitant occurrence of JAK2617F mutation and BCR/ABL translocation is a rare event. It is unclear if this is a result of the clonal evolution or a separately emergence of two clones and if it could lead to the progression to a more aggressive phase of the disease. We present the case of a 61-year-old man diagnosed and treated for polycythaemia vera(More)
BACKGROUND Patients with Myeloproliferative Neoplasms-(MPN) have a high risk of thrombotic complications. Portal vein thrombosis is a severe complication, which in many cases, appears at the onset of the disease; the risk factors are related to the presence of qualitatively altered thrombocytes and leucocytes, leading to their activation and appearance of(More)
Chronic myeloid leukemia (CML) is a hematopoietic stem cell disorder in which the diagnosis is confirmed by detection of a genetic marker: Philadelphia (Ph) chromosome in almost 90% of cases. Some of Ph1 negative patients, nevertheless, test positive for the abnormal gene, or the abnormal protein associated with this chromosome, when more sensitive studies,(More)
We present the case of a patient with a double transformation during the evolution of chronic hematopoietic malignancy - JAK2 positive chronic myeloproliferative neoplasm; the first transformation had occurred previous to the presentation in our Department, but the second transformation was observed in evolution and it was into a rapidly evolving disease,(More)
This article reports the molecular diagnosis findings regarding chronic myeloproliferative neoplasms made in a Molecular Biology Laboratory over a seven years’ experience (between 2009 and 2015). Ritus Biotec ltd is an ELN (European Leukemia Net) certified diagnostic laboratory for quantification of BCR-ABL. 1373 patients were subjected to Jak2 V617F(More)
Although the discovery of the BCR-ABL transcript and of the Jak2 V617F mutation lead to important clarifications, the pathogenesis of chronic myeloproliferative neoplasms remains extremely complex and still presents several unknowns. Our study reports the case of a 52 years old man with chronic myeloid leukemia (BCR-ABL positive) who, after 4 years of(More)
The 2016 WHO-CMP classification proposal defines a broad spectrum of JAK2 V617F mutated MPN phenotypes: normocellular ET, hypercellular ET due to increased erythropoiesis (prodromal PV), hypercellular ET with megakaryocytic-granulocytic myeloproliferation and splenomegaly (EMGM or masked PV), erythrocythemic PV, early and overt classical PV, advanced PV(More)
