"As a rough estimate, neurosurgeons do well to cure one in every
1,000-brain cancer patients they operate on. Radiation therapy slows
the growth of adult tumors, gaining perhaps one month of life, and may
result in a cure of only one in 500-1,000 patients. Similarly,
chemotherapy, despite 30 years of clinical trials, has not resulted in
the development of a single drug or drug combination that elicits more
than an occasional transient response in primary brain tumors."
