A  clinical trial  is a scientific study testing new medical treatments. Clinical trials are very important in improving future treatments for people with lymphoma. If you are interested in taking part in a clinical trial, ask your doctor if there is a trial that might be suitable for you. You might be referred to another centre if there is a suitable trial that your hospital is not taking part in. You don’t have to take part in a clinical trial if you don’t want to. If you don’t enter a trial, you are still treated with the best available treatment.

mg/m2 PO/IM daily for 4 to 6 weeks or until remission occurs; followed by twice weekly maintenance therapy with a total weekly dose of 30 mg/m2 PO/IM. Children receiving doses of 20 to 30 mg/m2/week ( to 1 mg/kg/week) may have better absorption and fewer GI side effects if methotrexate is administered either IM or subcutaneous. Several different combination chemotherapy regimens have been used for both induction and maintenance therapy in acute lymphoblastic leukemia. The prescriber should be familiar with new advances in antileukemic therapy.

The administration of immune agents to patients (known as Interferon-Beta-1b, or IFN-beta, therapy) has been widely used in the treatment and maintenance of multiple sclerosis (MS). Additionally, it is known that the risk of MS exacerbation is much higher in patients with active HHV-6 infection than in patients with a latent infection of the virus (Lafuente 2006, 2007; Chapenko 2003). In this new study from Madrid, researchers examined the effectiveness of IFN-1b therapy in multiple sclerosis patients with active HHV-6 infection. By monitoring the HHV-6 DNA levels of MS patients undergoing IFN-beta therapy, investigators were able to find that patients with active HHV-6 infection had a higher risk of severe MS relapse and poor response to IFN-beta therapy than patients …

Genetic loss on chromosomes 1p/19q (co-deletion or loss of heterozygosity [LOH] 1p/19q) is a consequence of a chromosomal translocation and describes a distinct tumour entity characterised by a prolonged natural history irrespective of treatment, and increased sensitivity both to radiotherapy (RT) and to chemotherapy ( Jenkins 2006) . LOH 1p/19q should be evaluated to support a diagnosis of oligodendroglioma.
The incidence of either 1p or 19q chromosomal deletions in OD is approximately 75%, the combined loss of 1p and 19q is observed in 25% to 48% of all ODs ( van den Bent 2013b; Cairncross 2013) . Additional chromosomal deletions, such as loss of heterozygosity for 9p, deletion of CDKN2A gene, deletions on chromosome 10 and chromosome 7 amplification, occur less frequently in anaplastic OD ( Bigner 1999; Jeuken 1999) . Oligodendroglial tumours with a classical histological appearance (perinuclear halo, chicken-wire vascular pattern) show 1p/19q co-deletions, whereas in tumours with an atypical appearance, other chromosomal abnormalities are often found (., TP53 mutations) ( Sasaki 2002; van den Bent 2003) . In AOD both the loss of 10q and the amplification of EGFR were found inversely related to 1p/19q loss, and were associated with poor chemosensitivity and short survival ( Hoang-Xuan 2001) . The mutually exclusive occurrence of 1p/19q loss and TP53 mutations, EGFR amplification, 10q loss, or PTEN mutations suggests that these tumours are in fact derived from different precursor cells. This hypothesis is supported by the marked differences in outcome and prognosis.
Recent genome sequencing of high-grade gliomas has identified mutations of the isocitrate dehydrogenase gene (IDH) as an early event in glioma genesis ( Yan 2009) . IDH1 mutations are present in 55% to 80% of grade III oligodendrogliomas and astrocytomas ( Sanson 2009) . Less frequently, glial tumours show mutations of the IDH2.
The presence of IDH 1 or 2 mutations is characteristic of a high-grade glioma developing from a lower grade precursor lesion ( Sturm 2012; Hartmann 2013) .
MGMT promoter methylation is highly associated with LOH 1p/19q and IDH mutations ( Sanson 2009) . Conversely, IDH1 was correlated with an absence of EGFR, absence of chromosome 7 polisomy, or absence of loss of chromosome 10.
