Younger patients and women have higher survival rates for glioblastoma, the deadliest form of brain cancer. Long-term survival rates are low, with only 10-30% of patients living more than five years. Symptoms include headaches, seizures, speech problems, and vision loss. Treatment includes surgery, radiation therapy, and chemotherapy, but long-term survival is modest.
Gender and age are the two most important factors determining glioblastoma survival rates. Studies show that younger patients and women live longer than older patients and men diagnosed with this form of brain cancer. Long-term survival rates for these brain tumors are defined as more than five years. Only between 10 and 30 percent of glioblastoma patients achieve long-term survival. Patients who experience seizures from the disease die more quickly.
Numerous studies have attempted to determine the factors influencing glioblastoma survival, taking into account occupational, environmental, and genetic risks. Studies have found that none of these variables determine survival three years after diagnosis. All of the patients in the study underwent surgery to remove the malignant tumor, in addition to radiation therapy, which is the standard postoperative treatment. Most patients also received chemotherapy.
Glioblastoma multiforme is a primary brain tumor affecting the central nervous system. It is considered the deadliest form of brain cancer because the abnormal cells grow rapidly. Only a small percentage of brain tumors fall into the category of glioblastoma, which can appear in the brainstem or spinal cord. It typically affects people over the age of 50, and most die within a year, making glioblastoma survival rates lower than all other cancers.
Symptoms typically include headaches that could be severe and cause seizures. Patients with these brain tumors might also experience speech problems and vision loss, depending on the exact location of the tumor. A marked change in personality occurs in some patients.
Diagnosing brain cancer commonly involves scanning with highly sensitive equipment that projects a three-dimensional image of the brain, enhanced by a harmless dye injected into the bloodstream. Biopsies are commonly done when the tumor is removed to determine if it is malignant. Doctors typically test for other conditions when a brain tumor is found, such as failure of other vital organs.
Neurosurgeons routinely attempt to remove the entire tumor without affecting the patient’s ability to function. Glioblastoma survival may not increase with the use of oral chemotherapy and radiation therapy, but it may improve quality of life and short-term survival. Long-term survival of glioblastoma is said to be modest after treatment, with only one to two percent of patients living longer than three years. Those who experience seizures from the tumor typically live about six months after surgery.
