BACKGROUND: Combination chemotherapy consisting of ifosfamide, methotrexate, etoposide, and prednisolone (IMEP) was active as first-line and second-line treatment for extranodal natural killer/T-cell lymphoma (NTCL). METHODS: Forty-four patients with chemo-naïve stage I/II NTCL were enrolled in a prospective, multicenter, phase II study and received six cycles of IMEP (ifosfamide 1.5 g/m(2) on days 1-3; methotrextate 30 mg/m(2) on days 3 and 10; etoposide 100 mg/m(2) on days 1-3; and prednisolone 60 mg/m(2) per day on days 1-5) followed by involved field radiotherapy (IFRT)...

BACKGROUND: Gestational trophoblastic neoplasia (GTN) includes a spectrum of disease ranging from hydatidifrom mole to choriocarcinoma. Low risk GTN is defined as persistent molar pregnancy with a WHO score lower than seven. The optimal chemotherapeutic regimen still remains controversial. AIM: The objectives of this study was to determine efficacy and safety of weekly intramuscular methotrexte in the treatment of low risk gestational trophoblastic neoplasia.(LRGTN) and also identify prognostic factors associated with treatment failure, necessitating second line chemotherapy...

PURPOSE: To describe the successful use of glucarpidase (carboxypeptidase G2) in the treatment of high-dose methotrexate-induced nephrotoxicity in a patient with osteosarcoma. SUMMARY: A 12-year-old female patient who had been diagnosed with low-grade right mandibular osteosarcoma was started on a protocol of cisplatin plus doxorubicin alternating with high-dose methotrexate. Following her first dose of methotrexte, she developed acute renal failure and higher than expected 24h methotrexate level of 478μM/L...

OBJECTIVE: To compare statistical models for the analysis of two-state disease processes. STUDY DESIGN AND SETTING: A two-armed randomized trial of patients with early rheumatoid arthritis (RA) treated by either combination therapy (sulfasazaline, methotrextate, prednisolone) or monotherapy (sulfasazaline). Disease activity (remission or relapse) was analyzed with the logistic regression model, the proportional hazards regression model, and the continuous-time Markov process model for panel data...

BACKGROUND: Although chemotherapy is associated with an increased risk of thrombosis, the pathogenic mechanisms by which chemotherapeutic agents exert prothrombotic effects are unclear. OBJECTIVES: In this study we explored the possibility that chemotherapeutic agents doxorubicin, epirubicin, 5-fluorouracil and methotrexate induce a procoagulant phenotype on vascular endothelial cells and/or on blood monocytes. METHODS: Thrombin generation was measured in defibrinated plasma exposed to chemotherapy-treated human umbilical vein endothelial cells (HUVECs)...

A 70-year-old immunocompetent woman who had been radiologically diagnosed with a left parasagittal meningioma 5 years previously developed a palpable subgaleal mass and underwent neurosurgery. Histologically the tumor was composed of thickened fibrotic dural tissue, infiltrated by a follicular lymphoma, of grade IIIB. A coexistent transitional meningioma had been infiltrated by the neoplastic lymphoid tissue. Two months after surgery, the patient developed evidence of extracranial dissemination of the lymphoma to the cervical lymph nodes and was treated with polychemotherapy plus Rituximab and intrathecal methotrextate...

Methotrexate is a folic acid analogue that has been used successfully for the treatment of ectopic pregnancy and, in conjunction with misoprostol, for medical abortions of early intrauterine pregnancies. To administer the most efficacious treatment requires knowledge of the mechanism underlying the induction of methotrexate-induced abortion. This study was designed to ascertain trophoblast integrity, proliferation and differentiation following administration of methotrexate. In addition, to determine if methotrexate affects the local uterine immune response, we ascertained the numbers and identities of decidual leukocytes following treatment...

Twenty-five patients with advanced squamous cell carcinoma of the head and neck were entered into this study. All patients had previously been irradiated and the majority had also undergone surgery for recurrent tumor. A low-dose regimen consisting of adriamycin, bleomycin, 5-fluorouracil, methotrexate, and vitamin A was prescribed, the median number of courses was four and a total of 95 were administered. Ten patients (40%) achieved objective responses (7 partial, 3 complete). The median duration of response was 14 weeks (range, nine to 60 weeks) with a median survival time of 38...

We describe a phase III trial on 200 patients with end stage squamous cell carcinoma of the head and neck. The patients were randomised to one of four treatment arms: cisplatinum alone, methotrexate alone, cisplatinum + 5-FU and cisplatinum + methotrexate. There was no significant difference in the response rates, but the survival of the cisplatinum arm was significantly better than that of the methotrexate arm. The survival of patients receiving cisplatinum as a single agent was longer than that of patients receiving cisplatinum in combination with methotrexate or 5-FU, but not significantly so...

Five analogues of methotrextate (MTX), 10-deazaaminopterin (10-DAM), and 10-ethyl-10-deazaaminopterin (10-EDAM) in which the glutamate moiety was replaced by either a gamma-methyleneglutamate or beta-hydroxyglutamate were synthesized and evaluated for their antifolate activity. These analogous are 4-amino-4-deoxy-N10-methylpteroyl-beta-hydroxyglutamic acid (1), 4-amino-4-deoxy-10-deazapteroyl-beta-hydroxyglutamic acid (2), 4-amino-4-deoxy-N10-methylpteroyl-gamma-methyleneglutamic acid (3, MMTX), 4-amino-4-deoxy-10-deazapteroyl-gamma-methyleneglutamic acid (4, MDAM), and 4-amino-4-deoxy-10-ethyl-10-deazapteroyl-gamma-methyleneglutamic acid (5, MEDAM)...
