PURPOSE: Genetic alterations such as activating KRAS and/or inactivating TP53 are thought to be the most common drivers to tumorigenesis. Therefore, we assessed phase I cancer patients with KRAS+/TP53+ mutations. RESULTS: Approximately 8% of patients referred to phase I clinical trials harbored concurrent KRAS and TP53 mutations. Patients who received a phase I trial therapy (n = 57) had a median OS of 12 months, compared with 4.6 months in those who were not treated (n = 106; p = 0...

The increased awareness of asplenia-related life-threatening complications has led to the development of parenchyma sparing splenic resections in past few years. The aim of this study is to retrospectively analyze the feasibility and safety of laparoscopic partial splenectomy (LPS) in selected emergency patients.From January 2013 to December 2015, there were 46 emergency patients, diagnosed with splenic rupture, admitted in our department. Selection criteria for LPS: (1) Preoperative CT scan revealed single pole rupture without spleen pedicle injury; (2) BP>90/60 mm Hg and heart rates <120 bpm; (3) No sigh of multiple organ injury...

Since low JAK2V617F allele burden (AB) has been detected also in healthy subjects, its clinical interpretation may be challenging in patients with chronic myeloproliferative neoplasms (MPNs). We tested 1087 subjects for JAK2V617F mutation on suspicion of hematological malignancy. Only 497 (45.7%) patients were positive. Here we present clinical and laboratory parameters of a cohort of 35/497 patients with an AB ≤ 3%.Overall, 22/35 (62.9%) received a WHO-defined diagnosis of MPN and in 14/35 cases (40%) diagnosis was supported by bone marrow (BM) histology (''Histology-based'' diagnosis)...

Objectives: To compare the mutational profiles of patients with primary myelofibrosis (PMF), polycythemia vera (PV), and essential thrombocytosis (ET). Methods: Next-generation sequencing results of 75 cases of PMF, 33 cases of PV, and 27 cases of ET were compared. Results: Mutation rates of ASXL1 and SRSF2 were significantly higher in PMF than in PV or ET. ASXL1 mutations appeared to be more frequently associated with risk of transformation to acute myeloid leukemia than JAK2 or TET2 mutations...

A 37-year-old woman was admitted to our hospital for purpura involving the extremities and thrombocytopenia. Prednisolone (PSL) was administered based on a diagnosis of idiopathic thrombocytopenic purpura (ITP), but was not effective for maintaining her platelet count within the normal range, which showed cyclic fluctuation corresponding to the menstrual cycle. Therefore, we discontinued PSL, and cyclic thrombocytopenia (CTP) was diagnosed. CTP is a rare disease which is usually treated as ITP but with no response...

BACKGROUND: Readmissions after hospitalization for pneumonia are common, but the few risk-prediction models have poor to modest predictive ability. Data routinely collected in the electronic health record (EHR) may improve prediction. OBJECTIVE: To develop pneumonia-specific readmission risk-prediction models using EHR data from the first day and from the entire hospital stay ("full stay"). DESIGN: Observational cohort study using stepwise-backward selection and cross-validation...

Extreme thrombocytosis induces an acquired thrombotic-hemorrhagic diathesis, and left uncontrolled is a harbinger of potentially fatal vascular complications. Currently, cytoreduction with medical therapy remains the mainstay of hyperthrombocytosis management. However, it offers a less-than-ideal option in situations where a rapid reduction in platelets is urgently needed, as in the presence of vital end-organ ischemia or to ameliorate of life-threatening hemorrhage. The role of thrombocytapheresis, or plateletpheresis, in hyperthrombocytosis has become increasingly obsolete given the proactive titration of cytoreductive therapies and early identification and correction of reversible causes of reactive thrombocytosis...

BACKGROUND: Thrombocytosis is a common phenomenon in critically ill patients. Although thrombocytosis is an independent risk factor for complications, it does not seem to influence mortality in intensive care (ICU) patients. OBJECTIVES: Our investigation aimed to evaluate the etiological and clinical relevance of a platelet count greater than 450 × 10(9)/l in ICU patients. MATERIALS AND METHODS: Patients admitted for a minimum of 4 days to an interdisciplinary ICU during a 45-month period were enrolled in this retrospective observational study...

Reported here is a case of upper gastrointestinal bleeding secondary to a peptic ulcer involving an extremely high platelet count of 989 × 10(9)/L. Myeloproliferative neoplasms were ruled out on the basis of gene mutation testing and a bone marrow biopsy. After the cessation of index bleeding, the platelet count decreased markedly. Thus, reactive thrombocytosis was considered as a possibility.

OBJECTIVE: Leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) is a collagen receptor that belongs to the inhibitory immunoreceptor tyrosine-based inhibition motif-containing receptor family. It is an inhibitor of signaling via the immunoreceptor tyrosine-based activation motif-containing collagen receptor complex, glycoprotein VI-FcRγ-chain. It is expressed on hematopoietic cells, including immature megakaryocytes, but is not detectable on platelets. Although the inhibitory function of LAIR-1 has been described in leukocytes, its physiological role in megakaryocytes and in particular in platelet formation has not been explored...

BACKGROUND: This study was designed to determine the clinical significance of preoperative thrombocytosis in patients with malignant peritoneal mesothelioma (MPM) undergoing operative cytoreduction (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). CRS and HIPEC have been associated with prolonged survival in patients with MPM and is the preferred treatment in select patients. However, patient selection criteria remain ill-defined for this operation that is also associated with significant morbidity and mortality...

POEMS syndrome is a paraneoplastic disorder secondary to an underlying plasma cell dyscrasia. By definition, all patients with POEMS syndrome must display polyneuropathy and monoclonal plasma cell disorder. In addition, at least one major criterion (Castleman's disease, sclerotic bone lesions, or vascular endothelial growth factor elevation) and one minor criterion (organomegaly, extravascular volume overload, endocrinopathy, skin changes, papilledema, thrombocytosis, or polycythemia) are required for diagnosis...

BACKGROUND: Unrecognized pseudohyperkalemia (PHK), defined as an artificial increase in measured potassium concentration, due to thrombocytosis and leukocytosis can lead to inappropriate patient treatment. Understanding the laboratory and patient characteristics that increase risk of PHK is key to preventing diagnostic errors. METHODS: Serum/plasma potassium results collected at 2 laboratories over 4years were selected based on blood cell counts collected within 24h and whole blood potassium concentrations determined within 2h of the serum/plasma sample...

For the patients with essential thrombocythemia (ET), systemic thrombosis presents as one of the most dangerous complications. It's been widely accepted that acute coronary syndrome (ACS) is a kind of thrombotic diseases. However, there are very few case reports about ET first presenting as ACS. For some patients diagnosed as ACS, but without markedly elevated platelet, underlying ET was missed. And there are some controversies in the principles and target of treatment in those patients. We reported three cases of ACS, in which the patients who did not have common risk factors for coronary artery diseases and presented only mild atherosclerotic stenosis during coronary angiography, one of which had recurrent coronary artery thrombosis...
