Washington: The widely used whole-brain radiation technique to treat brain cancer is not an effective strategy and results in more memory loss than treating patients with radiotherapy alone, study says.

First used in 1954, whole-brain radiation has long been a standard strategy for brain metastases (cancer cells that have spread to the brain from primary tumours in other organs in the body).

“The potential benefits of whole brain radiation therapy are far outweighed by the detriments of the therapy itself,” Paul Brown, professor of radiation oncology at the University of Texas’ MD Anderson Cancer Centre was quoted as saying in a Wall Street Journal report.

For the study, patients were assigned to either radiosurgery followed by whole-brain radiation or radiosurgery alone.

The research involved 213 patients, who had one to three small tumours or metastases in the brain.

Patients treated with both approaches performed significantly worse three months later on tests involving cognitive abilities.

Median overall survival was 7.5 months for those receiving both treatments and 10.7 months for those on radiosurgery alone.

Both whole-brain radiation and recurrent metastases are “bad for the brain.”

Lung cancer is the most common malignancy to spread to the brain, followed by breast cancer and melanoma.

The study was presented at the annual meeting of the American Society of Clinical Oncology on May 31. (IANS)

  • Researchers have discovered that Melatonin may help treat blood cancers like leukemia and lymphoma 
  • Melatonin’s involvement in regulation of circadian rhythms may help in coordination and synchronization of internal body functions 
  • Anti-cancer actions of melatonin are expected to be helpful in facilitating basic research 

Washington D.C. [USA], September 3, 2017: Researchers have discovered that blood cancers such as leukemia and lymphoma may be treated with a hormone produced by a small gland in the brain.

Melatonin, a hormone produced by a small gland in the brain may be able to treat blood cancers like leukemia and lymphoma, according to the researchers.

The findings suggest that melatonin performs a number of tasks such as boosting the immune response against cancer cells, inhibiting the growth of cancer cells and even protecting the healthy cells from chemotherapy’s toxic effects.

Melatonin’s involvement in regulation of circadian rhythms may help in the coordination and synchronization of internal body functions. The timings of he melatonin treatment may be grave in regard to their anti-cancer effects.

Senior author Yang Yang hopes that this information would prove helpful in the design of studies concerned with the therapeutic efficiency of melatonin in blood cancers.
