“Results from a large clinical study showed that testing pediatric brain tumors for genetic abnormalities is feasible and could play a role in guiding patients’ treatment.
“The study, published in Neuro-Oncology, showed that more than half of the samples taken from pediatric brain tumors and analyzed using genomic profiling had genetic irregularities that could influence how the disease was diagnosed or treated with approved drugs or agents being evaluated in clinical trials.”
“In a new study, Yale researchers identified a novel genetic defect that prevents brain tumor cells from repairing damaged DNA. They found that the defect is highly sensitive to an existing FDA-approved drug used to treat ovarian cancer—a discovery that challenges current practice for treatment of brain tumors and other cancers with the same genetic defect, said the scientists.
“The study was published on Feb. 1 by Science Translational Medicine.
“Certain malignant brain tumors and leukemias have mutations in genes known as IDH1 and IDH2. The mutations render the cancers sensitive to treatment with radiation therapy or chemotherapy, significantly increasing the survival time for patients with the mutations. To better understand this sensitivity, a cross-disciplinary team of researchers led by Yale created models of the mutation in cell cultures.”
Los Altos, California – January 25, 2017 – Cancer Commons, a nonprofit network of physicians, scientists and patients dedicated to helping each patient achieve the best possible outcome, announces the launch of a new program to identify personalized treatment options for children with brain cancer. The program is funded by a generous lead gift from Sheri Sobrato Brisson, a pediatric brain tumor survivor and advocate for children with serious illness, and her husband Eric Brisson.
“We are motivated to help children with brain cancer by giving their physicians and families access to the best treatment plans,” shares Sheri Sobrato Brisson. “Diagnosis is a frightening time, and patients and their families need help to quickly sort through vast, confusing amounts of information to assure them that they are making the best possible choices.” Continue reading…
“The use of tumor treating fields (TTFields) as a treatment for patients with brain tumors has, thus far, largely been focused on in glioblastoma, but an upcoming trial aims to expand the use of the device to the grade III patient population, says Daniel O’Connell, MD.
“Currently, the device is only FDA approved for use in grade IV brain tumors, but O’Connell, a neuro-oncologist at UCLA’s David Geffen School of Medicine, anticipates the FDA will grant its approval for use in grade III tumors within the next 2 to 3 months.”
“Attacking an aggressive brain tumor with immunostimulatory gene therapy while enhancing the immune system’s ability to fight it with immune checkpoint inhibitors might be a promising approach to treat patients with glioblastoma multiforme, a brain tumor currently associated with a very poor prognosis.
“A new kind of cancer study supports the idea that traditional treatment can be turned on its head, with patients given targeted therapy based not on where their tumors started but on their own genetic mutations.
“Researchers used a targeted melanoma drug to treat patients with a range of cancers, from lung cancer to brain cancer, who weren’t being helped by traditional chemotherapy any more. Even though they had many different types of tumors, they all had one thing in common — a genetic mutation called BRAFV600.
“It’s a mutation familiar to doctors who treat melanoma, the deadliest form of skin cancer. It’s seen in about half of melanoma cases. A pill called vemurafenib, sold under the brand name Zelboraf, specifically targets the mutation. It helps about half of patients with melanoma who have the mutation.
“The same mutation is sometimes seen in colon cancer, lung cancer, thyroid cancer, brain tumors and some blood cancers.”
