Could #Viagra, #Cialis and #Levitra Help Boost Colon Cancer Survival?

Sunday, Aug. 23, 2020 (Medicine24hrs Blog) — Erectile dysfunction (ED) drugs such as Viagra, Cialis and Levitra may do more than restore sexual function they may also prolong the lives of men with colon cancer.

in Sweden.

She colleagues focused on so-called “PDE5 inhibitors” –drugs that address impotence by regulating penile blood flow.

“There are two reasons why we considered the anti-cancer possibility of these drugs.

Prior studies suggested that ED drugs (Viagra Cialis Levitra) can inhibit tumor growth in mice and activity of a gene called PDE5A. In past work suggested colon cancer patients with lower PDE5A activity levels may live “significantly longer” than others.

To get a better handle on the cancer-fighting potential of the drugs, the researchers used a nationwide database to identify men in Sweden who were diagnosed with colon cancer between 2005 and 2014.

After excluding patients with late-stage cancer, researchers focused on more than 11,300 cancer patients who were not taking an ED drug (Viagra Cialis Levitra)and about 1,100 patients who were. (No one was instructed to use the drugs if they weren’t already doing so.)

Over more than four years of follow-up, about 10% of those who used an ED drug died, compared to 17.5% of patients who did not. The risk was even lower for those in the ED group who also had cancer surgery.

The explanation for the drugs’ anti-tumor effect isn’t yet clear. It could have to do with the beneficial impact EDs (Viagra Cialis Levitra) have on immune function, reduced cell death and chemotherapy sensitivity, she said.

But until researchers can get a better understanding, “it is not suggested for colon cancer patients to get EDs medications (Viagra Cialis Levitra) to control their cancer at this moment.

“The current evidence is not enough to provide recommendations, as our study is an observational study,” she stressed. “Clinical trials are necessary to confirm it.”

Still, Dr. Andrew Chan, a professor at Harvard Medical School and Massachusetts General Hospital in Boston who reviewed the study, said the findings were intriguing.

“The work extends a prior study from this group showing that these medications may reduce the risk of developing colorectal cancer,” he noted. “It is also biologically plausible that these medications may have an anti-cancer effect, since they are known to block a specific protein that may play a role in cancer development.”

The findings were recently published in the journal Nature Communications.
