should

should ganglioglioma be mentioned in the WHO grading system section?

  • A few thoughts...
    • I agree with the above unnamed poster. I think that there should be a reference to tumors of mixed glial/neuronal derivation such as ganglioglioma, dysembryoplastic neuroepithelial tumors etc.
    • Under "classification, by cell type" I think it's probably more correct to say that gliomas are classified by the type of mature glial cells that they most resemble. I think that there is increasing evidence that these tumors arise either from as yet unidentified pleuripotent glial/neuronal precursor cells or from glial cells that undergo some sort of de-differentiation to a pleuripotent state. As such, oligodendrogliomas are not nessisarily derived from oligodendrocytes. Genetic studies of mixed tumors generally show them to be a single clonal neoplasm rather than "collision tumors" as had previously been postulated. I think this is pretty good evidence for the pleuripotent precursor. --Jsonnen 17:06, 27 November 2005 (UTC)[reply]
Sounds good. I've done a minor rephrase to try to accomodate, but feel free to edit further. --Arcadian 19:55, 27 November 2005 (UTC)[reply]

Under "Experimental Therapies" it says "Only eight people have received this treatment and seven of them are still living." Could someone find out when these people were diagnosed, when they were treated and after how much time seven of them are / were still living ? --J-c 11:11, 10 June 2006 (UTC)[reply]

IDH1 mutation

I was reading this article as review for my research, and noticed the section on IDH1 mutation in glioma. It is good that this has been included, but I think that the explanation is lacking. The section reads, "The IDH1 and IDH2 genes are significant because they are involved in the

mitochondria. Mitochondria are involved in apoptosis." The mutation is likely significant because it causes a dramatic increase in 2-hydroxyglutarate (2HG) and depletion of alpha-ketoglutarate (aKG). 2HG is not ordinarily produced by cellular metabolism and may inhibit the prolyl hydroxylase enzymes responsible for ubiquinating and degrading Hif-1a. aKG levels also regulate Hif-1a stability. It is thought that the activity of the IDH mutant is such that it increases Hif-1a stability, upregulating the expression of hypoxic genes and increasing glycolysis. This lowers the cell's energy production but may allow it to survive the hypoxic environment of a tumor, while increasing its production of radicals and therefore the likelihood of further mutation. I am sorry that I do not have more time to cite this and include it in the article proper. --SRA, Radiology at UCSF 9:18 AM, 1 October 2010 —Preceding unsigned comment added by 169.230.228.61 (talk) 16:19, 1 October 2010 (UTC)[reply

I would also like to point out that this statement ' Tumor suppressor protein 53 (p53) is an early mutation' is factually incorrect. p53 is not a mutation; TP53, the gene which encodes p53, may be the site of mutations which promote cancer by inactivating p53. — Preceding unsigned comment added by 161.130.188.53 (talk) 23:29, 27 September 2012 (UTC)[reply]

Treatment for glioma stage 2

I would like to ask someone who knows what is the best treatment for glioma stage 2. Will it be okay if the patient will try first some medicines and what kind of medicines will it be? Before deciding to have an operation. My friend who has a glioma stage 2 say that he is afraid to have a surgery because of some side effects. So, will it be okay if he try first to drinking of medicines. —The preceding unsigned comment was added by Ecelisan (talkcontribs).

Micro RNAs

Did you know micro RNA's are being researched to cure glioma on the brain????

I'm reverting the good faith addition of the following until it can be discussed. We don't normally treat a Medical Hypotheses publication as sufficient for inclusion in disease articles:

There is an association of brain tumor incidence and malaria, suggesting that the anopheles mosquito, the carrier of malaria, might transmit a virus or other agent that could cause glioma and/or glioblastoma. [1]

While interesting, it needs to actually be investigated, published, and reviewed to fully meet

WP:MEDRS. Several other hypotheses might be raised for the same association. User:LeadSongDog come howl 22:16, 6 March 2010 (UTC)[reply

Investigation of links between gliomas and cell phone use

Cell phone use as a possible cause of glioma

The evidence of a linkage between cell phone use and gliomas should be mentioned. See: http://www.nytimes.com/2010/11/14/business/14digi.html?src=me&ref=general Teel Moran (talk)

Got a
wp:MEDRS? A newspaper business-section article touting a book doesn't really cut it. In any case the debate mentioned in that article isn't about using cell phones, it's about children holding them to their heads. The sensible precaution, if there were significant evidence of a risk, would be to ban built-in earphones in cellular handsets. Certainly, after this much study and worldwide adoption, the absence of real evidence is, at the least, evidence that any such effect is small for the exposures commonly seen. None of which means that it is sane to spend your life moving around the streets while on the phone. Unless you have a flashing red light on top of your vehicle, you probably shouldn't need a two-way radio inside it. But that's just my antediluvian perspective.LeadSongDog come howl! 19:54, 15 November 2010 (UTC)[reply

I have no interests in the cell phone industry, but as far as I know a connection between cell phone usage and brain tumors is highly unlikely, and usually denied by mainstream scientists. Actually there a physical reasons to believe so. Firstly, the power of cell phones is low (just a few Watt), so heating of the brain is minor (and probably unmeasurable). Secondly, the frequency of cell phone communication (in the 1-2 GHz range, decimeter wavelength range) is far below the frequency of ionising radation (X-Ray or gamma radiation) which is in the nanometer range or even smaller. Yes, ionising radiation may have harmful effects (due to quantum phenomena) even at low power. But the actual wavelength of cellphone radiation is much longer, see above.

This article appears to be a review article of a number of studies involving chlorotoxin for imaging and as a radio theraputic agent; although the trials are only phase II.

Anticoagulation

Many people with gliomas also require anticoagulation for other medical conditions. The risk of intracerebral bleeding is higher - doi:10.1111/jth.13387 JFW | T@lk 13:09, 20 June 2016 (UTC)[reply]
