Proton Beam Therapy For Glioblastoma

This lessens the chance of damage to surrounding normal brain tissue.

Proton beam therapy for glioblastoma.

A ground breaking clinical trial is treating glioblastoma with intensity modulated proton therapy impt. As a result doctors often reduce the optimal x ray radiation dose required to kill cancer cells. Unfortunately radiation affects both healthy and cancerous cells. Chemotherapy uses drugs to stop the growth of cancer cells.

Proton beam therapy offers an alternative. Proton beam therapy is a type of external beam radiotherapy. So the doctor using conventional radiation therapy x rays has to balance killing cancer cells with preserving healthy ones. Most patients undergoing radiation therapy for glioblastoma receive photon based radiation therapy such as intensity modulated radiotherapy imrt.

There are also other new discoveries in adult and childhood brain cancer research and treatment. Twenty three of 81 gbm patients who met the eligible criteria and consented to the protocol were treated with x ray radiation therapy 50 4 gy in 28 fractions in t2 high areas and proton beam therapy 46 2 gye in 28 fractions in gadolinium enhanced volumes 6 hours after x ray radiation therapy concurrent with nimustine. It is used to help reduce the risk of long term side effects that can sometimes develop after standard radiotherapy. Proton therapy is a type of radiation often used for patients with glioblastoma.

Proton beam therapy is only suitable for a small number of people. Proton therapy provides pinpoint focusing of the radiation beam to the tumor. These charged particles damage the dna of cells ultimately killing them by stopping their reproduction and thereby eliminating the tumor. Twenty three of 81 gbm patients who met the eligible criteria and consented to the protocol were treated with x ray radiation therapy 50 4 gy in 28 fractions in t2 high areas and proton beam therapy 46 2 gye in 28 fractions in gadolinium enhanced volumes 6 hours after x ray radiation therapy concurrent with nimustine hydrochloride or temozolomide.

Cancerous cells are particularly vulnerable to attacks on dna. Imrt uses multiple x ray beams made of photons at different angles to treat the area where the tumor was removed and any tumor left.
