Polycythemia vera (PV) is a myeloproliferative disorder most commonly associated with JAK2V617F mutation. Cerebral venous sinus thrombosis (CVST) has a wide range of etiologies and PV is one of them. CVST associated with PV has a poor prognosis. Some patients with classical PV lack
A 45-year-old male patient presented with gradual onset of headache, vomiting and blurring of vision of 28 days duration. Ophthalmological examination revealed normal anterior segment and pupillary reflex. No abnormality was detected in the vitreous. Optic disc showed features of advanced
A 2-year-old, castrated male, mixed-breed dog presented with a 1-month history of red eyes and intermittent vomiting and a 2-week history of polyuria and polydipsia. Bilateral anterior uveitis and active chorioretinitis in the left eye were found on ophthalmic examination. Complete blood counts
Migraine-like cerebral transient ischemic attacks (MIAs) and ocular ischemic manifestations were the main presenting features in 10 JAK2(V617F)-positive patients studied, with essential thrombocythemia (ET) in 6 and polycythemia vera (PV) in 4. Symptoms varied and included cerebral ischemic attacks,
Few treatment options exist for patients with myelofibrosis (MF), and their survival is significantly shortened. Activating mutation of the JAK2 tyrosine kinase (JAK2(V617F)) is found in approximately 50% of MF patients. CEP-701 is a tyrosine kinase inhibitor that inhibits JAK2 in in vitro and in
Phase II study of YNK01 (1-beta-D-arabinofuranosylcytosine-5'-stearylphosphate), a derivative of cytosine arabinoside, on hematological malignancies was conducted by multi-institutional cooperative group. YNK01 was administered orally at dose of 100-300 mg/body/day for more than 2 weeks. The number
Of 501 patients with chronic myeloproliferative diseases (c-MPD) 18 developed thrombosis of major abdominal vessels including 6 with hepatic vein thrombosis (Budd-Chiari syndrome). The complication was seen in 14 of 140 (10%) patients with polycythemia vera (PV), 3 of 23 (13%) patients with
Hydroxyurea (HU) is a ribonucleotide reductase inhibitor used to treat myeloproliferative diseases including polycythemia vera (PV) and essential thrombocythemia (ET). We describe an 82-year-old male who was started on HU 500 mg three times weekly for the treatment of PV. Eight days after initiation
A phase II study of the oral agent methyl 6-[3-(2-chloroethyl)-3-nitrosoureido]-6-deoxy-alpha-D-glucopyranoside (MCNU tablet) for myeloproliferative disorders was performed. Fifty-two patients were treated with MCNU tablets and 43 patients were evaluated for clinical effects and 45 for adverse
Sixty-seven patients with hematological malignancies and 4 with cancers were evaluated in this study. Standard administration of MCNU was instituted intravenously using 50-100 mg/m2 every 2 or 4 weeks, whereas some cases were treated with a higher dose therapy. Of 10 patients with chronic
A phase II study of MCNU tablet has been performed on 70 patients with hematological disorders including mostly myeloproliferative disorders. MCNU tablet was given p.o. at a dose of 50 mg daily for 2-6 days (total 100-300mg) as one course with average intervals of 3 to 5 months or more for patients
Seventeen patients with myeloproliferative disorders and one patient with chronic myelomonocytic leukemia (CMMoL) were treated with ranimustine++ (MCNU), and the efficacy was evaluated. MCNU was given intravenously by drip infusion at an usual dose of 100 approximately 150 mg with intervals arranged
OBJECTIVE
Myelofibrosis is a myeloid malignancy associated with anemia, splenomegaly, and constitutional symptoms. Patients frequently harbor JAK-STAT activating mutations that are sensitive to TG101348, a selective small-molecule Janus kinase 2 (JAK2) inhibitor.
METHODS
In a multicenter phase I
