Long-term survivors of primary central nervous system lymphoma.

Objective: In this study, we provide long-term outcome data of patients with primary central nervous system lymphoma.

Methods: The long-term outcomes of PCNSL patients diagnosed between 1982 and 2006 were reviewed. Neurological late neurotoxicity symptoms, neuroradiological brain atrophy and leukoencephalopathy were evaluated.

Prognostic significance of S-phase fractions in peritumoral invading zone analyzed by laser scanning cytometry in patients with high-grade glioma: A preliminary study.

The predominant characteristic of malignant glioma is the presence of invading tumor cells in the peritumoral zone. Distinguishing between tumor cells and normal cells in a peritumoral lesion is challenging. Therefore, the aim of the present study was to investigate the cell-cycle phase measurements of fixed paraffin-embedded specimens from the peritumoral invading zone of high-grade gliomas using laser scanning cytometry.

[Application of brain diffusion-weighted imaging performed using readout segmentation of long variable echo trains].

We report the preliminary use of the readout segmentation of long variable echo trains(RESOLVE)sequence, a novel magnetic resonance(MR)scanning technique based on a readout segmented echo planar imaging(EPI)strategy. RESOLVE enables high-resolution diffusion-weighted imaging(DWI)by minimizing susceptibility distortions and T2* blurring. The software for this sequence was provided by Siemens AG, Germany.

Results of treatment of 112 cases of primary CNS lymphoma.

Background: Chemotherapy with or without radiotherapy is the mainstay of treatment for primary central nervous system lymphoma (PCNSL). High-dose methotrexate (MTX) is the most effective drug available to treat these lesions, either as a single agent or in combination with other drugs. Due to the lack of well-conducted randomized trials, the optimal treatment remains controversial.

Salvage therapy and late neurotoxicity in patients with recurrent primary CNS lymphoma treated with a modified ProMACE-MOPP hybrid regimen.

We report the efficacy of salvage therapy with a modified ProMACE-MOPP combined with radiation in patients with primary central nervous system lymphoma (PCNSL). Thirty-two immunocompetent patients were treated with a regimen of pirarubicin, cyclophosphamide, etoposide, vincristin, and methotrexate (MTX: 500 mg/m(2)) administered in 21-day cycles. Patients received 20 Gy of whole-brain radiotherapy after three cycles of chemotherapy.

Modified ProMACE-MOPP hybrid regimen with moderate-dose methotrexate for patients with primary CNS lymphoma.

The object of this study was to assess the estimation of 2- and 5-year overall survival and tumor response and the frequency and severity of treatment morbidity with a modified ProMACE-MOPP hybrid protocol in patients with primary CNS lymphoma (PCNSL). Thirty-two immunocompetent patients were treated with a regimen of pirarubicin, cyclophosphamide, etoposide, vincristine, and methotrexate (500 mg/m(2)) administered in 21-day cycles. Intraventricular 10 mg of methotrexate was given for eight cycles once a week.

Intrathecal chemotherapy for patients with meningeal carcinomatosis.

Background: Meningeal carcinomatosis (MC) is increasing, and these patients have a poor prognosis. We analyzed the effects of intrathecal (IT) chemotherapy for these patients.

Methods: Patients received both methotrexate (MTX) (15 mg/m(2)) and prednisolone (10 mg/m(2)) 6 times in 2 weeks by Ommaya reservoir, along with cytosine arabinoside (10 mg/m(2)) for 4 doses of MTX.

Selection of surrogate marker genes in primary central nervous system lymphomas for radio-chemotherapy by DNA array analysis of gene expression profiles.

Primary central nervous system lymphomas (PCNSLs) are extra nodal B-cell non-Hodgkin's lymphomas with primary manifestation in the brain, and their incidence has been increasing among both immunocompetent and immunocompromised populations. Samples of oligodendroglioma (n=5), glioblastoma (n=7), PCNSL (n=6), and normal brain (n=3) were studied (total of 21 samples) using cDNA array technology. The hierarchical clustering algorithm was used to obtain a phylogenetic tree, and it revealed a striking feature: PCNSL was clearly separated.

[A critical pneumonia by multidrug-resistant Enterococcus faecium in a chronic hemodialysis patient. A case report].

Enterococcus faecium is usually known as a pathogen of nosocomial infections in compromised patients. Recently it is a problem that some of the E. faecium become resistant to many antibiotics.

Adrenocorticotropin-producing pituitary carcinoma with metastasis to the liver in a patient with Cushing's disease.

A 61-year-old woman who had a nonfunctioning pituitary tumor removed was later found to have a pituitary carcinoma with metastasis to the liver that produced adrenocorticotropic hormone (ACTH), causing Cushing's disease. Despite the second removal of the pituitary tumor, Cushing's disease persisted. Endocrinologic examination demonstrated marked elevation of plasma ACTH, beta-endorphin, and serum cortisol concentrations, which were not suppressed by low- or high-dose dexamethasone administration.

[Pulmonary pseudosequestration receiving arterial supply from the right coronary artery: a case report].

A 66-year-old female had been treated by hemodialysis since 1996. She was admitted to our hospital with acute pneumonia in January 2001. During admission, ischemic heart disease was identified.
