A brain tumor occurs when abnormal cells form within the brain. There are two main types of tumors: malignant tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved. Where symptoms exist, they may include headaches, seizures, problems with vision, vomiting and mental changes. Other symptoms may include difficulty walking, speaking, with sensations, or unconsciousness.
Cancer Research UK (CRUK) is the world's largest independent cancer research organization. It is registered as a charity in the United Kingdom and Isle of Man, and was formed on 4 February 2002 by the merger of The Cancer Research Campaign and the Imperial Cancer Research Fund. Cancer Research UK conducts research using both its own staff and grant-funded researchers. It also provides information about cancer and runs campaigns aimed at raising awareness and influencing public policy.
A glioma is a type of tumor that starts in the glial cells of the brain or the spine. Gliomas comprise about 30 percent of all brain tumors and central nervous system tumours, and 80 percent of all malignant brain tumours.
The Institute of Cancer Research is a public research institute and a member institution of the University of London in London, United Kingdom, specialising in oncology. It was founded in 1909 as a research department of the Royal Marsden Hospital and joined the University of London in 2003. It has been responsible for a number of breakthrough discoveries, including that the basic cause of cancer is damage to DNA.
Oligodendrogliomas are a type of glioma that are believed to originate from the oligodendrocytes of the brain or from a glial precursor cell. They occur primarily in adults but are also found in children.
Small-cell carcinoma is a type of highly malignant cancer that most commonly arises within the lung, although it can occasionally arise in other body sites, such as the cervix, prostate, and gastrointestinal tract. Compared to non-small cell carcinoma, small cell carcinoma has a shorter doubling time, higher growth fraction, and earlier development of metastases.
Glioblastoma, previously known as glioblastoma multiforme (GBM), is one of the most aggressive types of cancer that begin within the brain. Initially, signs and symptoms of glioblastoma are nonspecific. They may include headaches, personality changes, nausea, and symptoms similar to those of a stroke. Symptoms often worsen rapidly and may progress to unconsciousness.
Bevacizumab, sold under the brand name Avastin among others, is a medication used to treat a number of types of cancers and a specific eye disease. For cancer, it is given by slow injection into a vein (intravenous) and used for colon cancer, lung cancer, glioblastoma, and renal-cell carcinoma. In many of these diseases it is used as a first-line therapy. For age-related macular degeneration it is given by injection into the eye (intravitreal).
Adjuvant therapy, also known as adjunct therapy, adjuvant care, or augmentation therapy, is a therapy that is given in addition to the primary or initial therapy to maximize its effectiveness. The surgeries and complex treatment regimens used in cancer therapy have led the term to be used mainly to describe adjuvant cancer treatments. An example of such adjuvant therapy is the additional treatment usually given after surgery where all detectable disease has been removed, but where there remains a statistical risk of relapse due to the presence of undetected disease. If known disease is left behind following surgery, then further treatment is not technically adjuvant.
Cilengitide is a molecule designed and synthesized at the Technical University Munich in collaboration with Merck KGaA in Darmstadt. It is based on the cyclic peptide cyclo(-RGDfV-), which is selective for αv integrins, which are important in angiogenesis, and other aspects of tumor biology. Hence, it is under investigation for the treatment of glioblastoma, where it may act by inhibiting angiogenesis, and influencing tumor invasion and proliferation.
Carmofur (INN) or HCFU (1-hexylcarbamoyl-5-fluorouracil) is a pyrimidine analogue used as an antineoplastic agent. It is a derivative of fluorouracil, being a lypophilic-masked analog of 5-FU that can be administered orally.
Cancer can be treated by surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy and synthetic lethality, most commonly as a series of separate treatments. The choice of therapy depends upon the location and grade of the tumor and the stage of the disease, as well as the general state of the patient. Cancer genome sequencing helps in determining which cancer the patient exactly has for determining the best therapy for the cancer. A number of experimental cancer treatments are also under development. Under current estimates, two in five people will have cancer at some point in their lifetime.
The University of Nottingham School of Pharmacy was founded in 1925 and is located in the University Park Campus of the university. The school also offers courses at the University's Malaysia campus in Kuala Lumpur with students spending two years in Malaysia and two years in Nottingham The School also offers the first joint Pharmacy course with China, with the Tianjin University of Traditional Chinese Medicine. The current head of The School is Professor Clive Roberts (2013-).
Genta Incorporated was a biopharmaceutical company started in La Jolla, California, which discovered and developed innovative drugs for the treatment of patients with cancer. Founded in 1989 by a highly skilled entrepreneur, the company focused on a novel technology known as antisense, which targets gene products that are associated with the onset and progression of serious diseases. At that time, only Ionis Pharmaceuticals, Inc. was conducting significant research with this technology. Antisense is a short span of oligonucleotides – modified DNA structures ranging from about 12-24 bases that selectively bind to specific RNA. The intent is to block expression of an aberrant protein that contributes to the disease of interest. Genta in-licensed three different antisense molecules that blocked Bcl-2, a fibroblast growth factor (FGF), and the gene c-myb, respectively.
Anaplastic astrocytoma is a rare WHO grade III type of astrocytoma, which is a type of cancer of the brain. In the United States, the annual incidence rate for anaplastic astrocytoma is 0.44 per 100,000 people.
Temozolomide (TMZ), sold under the brand name Temodar among others, is a medication used to treat brain tumors such as glioblastoma and anaplastic astrocytoma. It is taken by mouth or via intravenous infusion.
Alternating electric field therapy, sometimes called tumor treating fields (TTFields), is a type of electromagnetic field therapy using low-intensity, intermediate frequency electrical fields to treat cancer. A TTField-generating device manufactured by the Israeli company Novocure is approved in the United States and Europe for the treatment of newly diagnosed and recurrent glioblastoma multiforme (GBM), and is undergoing clinical trials for several other tumor types. Despite earning regulatory approval, the efficacy of this technology remains controversial among medical experts.
CUSP9 [Coordinated Undermining of Survival Paths] is one of several cancer treatment protocols using re-purposed older drugs to interfere with cancer cell's growth signaling rather than directly killing them with cytotoxic drugs. CUSP9 is a treatment specifically targeted to glioblastoma that adds to a traditional cancer cell killing drug, temozolomide, nine older, non-cytotoxic drugs to block growth factors that enhance or drive glioblastoma growth [aprepitant blocks NK-1, auranofin inhibits thioredoxin reductase, captopril inhibits angiotensin converting enzyme, celecoxib blocks cyclooxygenase-2, disulfiram blocks aldehyde dehydrogenase, itraconazole blocks Hedgehog signaling, minocycline inhibits metalloproteinase-2 and -9, quetiapine inhibits RANKL, sertraline inhibits Tissue Factor]. These targets have been shown to be active in glioblastoma.
Anaplastic oligodendroglioma is a neuroepithelial tumor which is believed to originate from oligodendrocytes, a cell type of the glia. In the World Health Organization (WHO) classification of brain tumors, anaplastic oligodendrogliomas are classified as grade III. In the course of the disease, they can degenerate into WHO grade IV glioblastoma. The vast majority of oligodendrogliomas occur sporadically, without a confirmed cause and without inheritance within a family.
