What is the treatment of recurring glioblastoma?
The most common brain tumors, glioblastomas, affect brain support cells. Recurrent glioblastoma is the result of tumors developing after treatment, sometimes in areas distant from the original point of the tumor. Most of the treatment of this form of cancer attempts to control the revival of tumors that can be in multiple places.
Initial treatment of recurrent glioblastoma usually includes surgery. Whenever possible, doctors usually try to consume as many tumor as possible to prevent the tumor from later preventing a tumor. Sometimes, instead of invasive surgery, doctors decide for radiosurgery, where the focused radiation focuses on tumor sites. If there are more tumors in different places, radiosurgery is often less harmful with a much less healing time.
Radiation therapy is usually another additional therapy for this form of glioblastoma. Targeted radiation is usually used, although it is not as focused as radiosurgers. Studies did not show that exposureThe whole brain of radiation significantly improves the level of survival. However, when radiation was used to attack the area where surgery was carried out, the rate of survival has more than doubled. This may be the result of the radiation ability to kill any tumor cells that have not been removed by surgery.
Chemotherapy uses strong drugs to attack cancer cells. Many types of chemotherapy are more global than surgery, making it a useful tool for the treatment of recurring glioblastoma. Drugs such as Templomide are often used because they disrupt the ability of tumor cells to replicate.
There are also some targeted types of chemotherapy. Bevacizumab can be injected near tumor sites and works to prevent tumor cells from generating blood vessels to provide their nutrition. Combined with more traditional chemotherapy, bevacizumabby was found to significantly improveE of survival peace. This combination of therapies also reduced brain swelling, which alleviated the need to take other medicines to check this symptom.
recurrent glioblastoma can cause a number of harmful effects on tissue in the area, including seizures and headache from swelling. Patients with this cancer generally have to take other medicinal therapies to avoid these effects. These drugs may include anticonvulsants and steroids that can reduce swelling and relieve pressure.
As with most cancer treatment, a combination of these therapies usually leads to the best chance of survival. Some doctors have focused on using radiosurgery and chemotherapy to check the recurring glioblastoma. Both of these therapies can quickly treat several tumor sites and cooperate to prevent tumors from re -discovery. One study has found that a combination of therapies in this way can improve the survival rate by several months.
