Survival Expectancy of Glioblastoma patients
The first thing I wanted to know when I learned that my wife got glioblastoma was how long she would live from the time of diagnosis. I guess this would be the case of most caregivers. Here are some of the information I gathered about life expectancy of GBM. 1) 13 months (Harrison's principles of internal medicine) Treated with dexamethasone alone following surgery, the mean survival of patients <65 years with glioblastoma is 7 to 9 months. Survival is prolonged to 11 to 13 months with radiation therapy. Focal brain irradiation is less toxic and is as effective as whole-brain radiation for primary glial tumors. Radiation is generally administered to the tumor mass, as defined by contrast enhancement on a CT or MRI scan, plus a 3- to 4-cm margin. A total dose of 5000 to 7000 cGy is administered in 25 to 35 equal fractions, 5 days per week. Chemotherapy is marginally effective and is often used as an adjuvant therapy following surgery and radiation therapy. * Based on this informa...
