Republican Senator John McCain is probably the most famous person with brain cancer. The type of cancer that diidapnya is glioblastoma, the most deadly type of cancer. Since McCain announced this news last year, he has undergone surgery and chemotherapy. There is no cure for this type of cancer, and even with treatment, most people will not be able to survive for more than three years after being diagnosed.
Surgeons often can not lift the entire tumor or the cancer can be attached to the spine. This type of tumor is often spread which makes it difficult to remove completely.
Untreated, the risk of survival is only a few months. Even with treatment, the chance of survival for two years is only 30 percent, according to the American Brain Tumor Association
What raises hope is the presence of several promising new treatment methods.
An example of this case is Lori Mines. He is a 40-year-old woman and mother who was diagnosed with stage 4 brain cancer two years ago. He felt a very bad headache followed by a stroke. When the doctors ordered brain scans, they found two large brain tumors, one on each side of his brain. One of the tumors is attached to the column of the spine and can not be completely removed. After Surgery, Mines Undergoing a Delisting Process
"I'm even crazy about that … Basically I just want to focus on healing," he said.
Even brain tumors that are not clbadified as cancer can be fatal if they affect the part of the brain responsible for the vital functions of the body. The treatment often includes surgery, chemotherapy or radiation therapy or a combination of all of these treatments.
Glioblastoma is the most common type of brain cancer and its relative number to survive for five years is less than 6%. he is realistic, although he hopes to live longer. He said that he would only fight for himself, her husband and her granddaughter.
"I insisted that there was no other choice," he said
Duke Health scientists discovered that they could increase the probability of survival for some patients by directly injecting the polio virus that has been modified for the tumor. Other researchers are trying to attack the tumor by the immune system.
Arnab Chakravarti, head of the Department of Radiation Oncology at Ohio State University where he specializes in brain cancer. Dr. Chakravarti says medical researchers are testing new clinical trials, targeted therapies and immune therapies
"There is a lot of hope for such patients," he said. declared
. , brain tumors that can be cancerous or benign. The researchers found that they can double the life expectancy of patients who already have a distinctive biological marker, cell, or molecule contained in a particular type of tumor. This biomarker helps doctors decide which type of treatment is most effective at shrinking the tumor.
"It is important to provide treatments specifically tailored to each patient and that is why biomarkers, prognostics and predictive biomarkers become so important," said Chakravarti.His study was published in the journal JAMA Oncology.
Experts say that testing of genetic markers would be the norm for patients with malignant brain tumors.Experts are also exploring targeted pharmacotherapy as part of a treatment designed for each individual. The hope is that the diagnosis of brain cancer is no longer an inevitable death sentence. [ww]
