Brain cancer kills men more often, more quickly than women: Study

Brain cancer kills men more often, more quickly than women: Study

A new study showed that men are more likely than women to die of brain cancer because of fundamental differences in the way the cancer develops, with important implications for the future of treatment.

Men diagnosed with cancer have been proven to die more often and more quickly than women, which led researchers at Washington University in St. Louis, Missouri to find out why, wrote

Their conclusion was that very different processes are at work in brain cancer-causing tumors depending on the host's gender. Although the researchers focused on the relatively rare type of glioblastoma, they believe that other cancer types will be shown to work the same way.

The study, titled 'Brain tumors' battle of the sexes' and published in Science Translational Medicine, showed that the role of gender in the development and treatment of this type of cancer goes far beyond hormones or lifestyle differences, which vary depending on a person's age and region of the world.

"We observed tremendous genetic sex differences in the tumors of glioblastoma patients that correlated with survival," said Jingqin Rosy Luo, one of the study’s researchers, suggesting that not only do the cancer cells develop differently in men than women, but that this fact was likely at the root of the terminal outcomes.

One of the other researchers, neuro-oncologist Dr. Josh Rubin, added to this conclusion in an interview with NBC News, saying that men and women are different as male blastocysts develop more rapidly as a result of chromosomal differences at the genetic level.

"The work that we have been doing would suggest that molecular mechanisms are just fundamentally different in males and females," he said.

As a result of their findings, the study's authors suggest implementing "personalized cancer treatment" methods, which involves DNA testing of patients' tumors.
