The success rate of spinal cancer treatment in adults between 20 and 44 with meningioma is 92 percent. The American Cancer Society uses the five-year survival rate to measure success. The rates decrease as patients grow older and vary according to the tumor type, according to the American Cancer Society.
The location of the tumor within the spine and the overall health of the patient also affect success rates. Tumors in difficult-to-access locations make surgery more difficult and lower the success rates. The best source of information concerning a patient's chances of survival is his own doctor, advises the American Cancer Society.
