With a few exceptions, glioblastoma (GBM) remains largely incurable, and the U.S. Food and Drug Administration (FDA) has approved few treatments for the disease. Surgery (when feasible), radiation, and temozolomide are used in most patients. But even if a newly diagnosed tumor can be surgically excised, recurrences are too common.
In this blog post, I simply list some of the new treatments available in clinical trials for GBM and other high-grade brain tumors. Only drugs that have at least some preliminary results of activity are included, and the list is not meant to be fully comprehensive. The interested reader can judge for herself what might be of interest, keeping in mind that no single treatment is suitable or will work for all GBM patients. Continue reading…
“An analysis of a patient’s deadly brain tumor helped doctors at Smilow Cancer Hospital identify new emerging mutations and keep a 55-year old woman alive for more than five years, researchers report in the journal Genome Medicine.
“The median survival rate for patients with glioblastoma multiform (GBM) is only 15 months, but three separate genomic analyses of the tumor identified new mutations that allowed doctors to adjust treatment and keep the patient alive for over five years, through two recurrences of the cancer.”
“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.”
