GBM in cancer is abbreviation for glioblastoma multiforme which is grade 4 brain tumor. It is the most aggressive and common type of brain cancer. Glioblastoma cells has fast growth and multiply quickly destroying the surrounding tissues. It has poor prognosis for survival, however, the therapy is initiated which is known as GBM chemotherapy.

Chemotherapy is used as a primary treatment when a tumor cannot be surgically removed. It involves the circulation of medication in patients bloodstream to kill cancer cells. It is combined with radiation and administered via different cycles. In most cases, patients start chemotherapy two to six weeks after surgery for tumor biopsy or resection.

2.Define GBM Chemotherapy Drugs?

GBM chemotherapy drugs are medications used to treat brain tumor in adults. These are effective medications that works by destroying rapidly dividing cancer cells. The common chemotherapy drugs for glioblastoma are alkylating agents and antibodies such as Temozolomide, Carmustine, and Bevacizumab etc.

These drugs are available in oral form such as pills and tablets and injection form. Depending upon various circumstances, they may be administered orally, injected into a vein or intrathecal space of the spine.

3.Explain Some Of The Advantages Of GBM Chemotherapy Drugs?

GBM chemotherapy drugs are vital for treating the harsh form of brain cancer. These drugs offer convenient way for administration, help improving quality of life, and are flexible enough to be combined with other treatments. Let us explore in the below paragraphs about potential benefits of GBM chemotherapy drugs!

Convenient Administration
