How long is the survival period after secondary surgery for gliomas

The median survival period of glioma grade II is between 8 and 10 years, but the exact length of survival is related to tumor infiltration, treatment, and individual differences. The World Health Organization classifies gliomas into 4 grades, grade I and II are benign, called low grade gliomas, and grade III and IV are malignant, called high grade gliomas. For patients with early stage grade II glioma, if they can be detected, diagnosed and treated as early as possible, the tumor can be completely resected through radical surgery before it spreads and metastasizes, achieving a relatively complete cure, and the patients are able to survive for a long time. However, some gliomas miss the opportunity of surgery and can only be controlled by means of radiotherapy and chemotherapy, but the effect is very limited. Therefore, there is no detailed time limit for how long a patient can survive, and the length of time is affected by many factors, including the infiltration around the tumor and the relevant treatment, and also has a certain relationship with individual differences. Overall, the five-year survival rate for stage II glioma is relatively high.
