How beta blockers can help melanoma patients live longer

ANI  |  Washington D.C. [USA] 

According to a research, patients may live longer if they take beta blockers, a class of drugs used to manage abnormal rhythm and prevent attacks.

Researchers at Penn State found that patients who received while taking a specific type of beta blocker lived longer than patients who received alone.

In a follow-up experiment with mice, the researchers saw the same

Dr. Todd Schell, at Penn State College of Medicine, said that because are already widely available, the findings could indicate a simple way for physicians to better treat their patients.

"The type of beta blocker we found to be effective against -- pan -- was actually the least prescribed," Schell said. "Most patients are either prescribed beta 1 selective blockers or are not taking at all. This means there's a large population of patients who may be eligible to take pan while being treated with And because are already approved, it's something we know is safe and can be very quickly implemented in patient care."

Patients with metastatic melanoma, or that has spread to other parts of the body, often have a poor prognosis, and while some forms of -- treatments that boost the body's immune system to fight -- are promising, response rates are less than 35 percent.

Previous research has shown that physiological stress prevents the immune system from fighting effectively, while lower stress boosts the benefits of anti-treatments. The researchers were curious about whether lowering stress with would improve outcomes in patients treated with

"slow your rhythm, but they can also affect immune cells and improve immune function," Schell said.

"We wanted to see if there would be a correlation between the patients were taking for another condition and their response to For metastatic melanoma, there are currently three different types of approved for use, and we specifically looked at that population of people."

In studies developed by Dr. Kathleen Kokolus, the researchers analyzed data from 195 metastatic patients who were treated with between 2000 and 2015, 62 of which were also taking

They compared survival between the patients taking beta 1-selective blockers, pan and no

While there was little difference in how long patients taking beta 1-selective blockers or no lived, the indicate that patients taking pan lived significantly longer than the others.

Five years after immunotherapy, about 70 percent of patients receiving pan were still alive, versus about 25 percent of those taking beta 1-selective blockers or no at all.

To help explain the results, the team performed a parallel experiment in mice with They treated the mice with and with or without the pan beta blocker propranolol.

The researchers found that the propranolol growth and increased survival when combined with

Dr. Joseph Drabick, physician and professor of at Penn State College of Medicine, said the suggest that reducing physiological stress with can help improve the effectiveness of and survival for patients.

"These new are great, but they don't work for everyone," Drabick said. "So how can we make these treatments better? We saw that for patients taking pan beta blockers, there was a dramatic improvement in survival, and we were able to duplicate these findings in mice and see the exact same phenomenon."

Drabick also said the study was a good example of the benefits of finding new uses for drugs that have been around awhile.

"The benefit of this is that already have a long history of safety in people, and they're cheap and generic," Drabick said. "And now they have the potential to augment some of these newer drugs to help people with "

The study has been published in the journal OncoImmunology.
