Keytruda and squamous cell skin cancer?

I just finished 2 years of Keytruda (successful in keeping the cancer at bay), and have noticed an increase in squamous cell skin cancers.  I have had 5 this year (two of which required plastic surgery to remove).  My onc said she thought she had heard something about a correlation between immunotherapy and skin cancers, but wasn't sure.  Has anyone heard this, or do you know of any studies?

Hi Chuck, Welcome to Grace. 

Hi Chuck,


Welcome to Grace.  I'm so sorry you're going through this.  I hope keytruda was still working and you're just done or taking a break. 


There is no belief in the science community that keytruda causes squamous cell skin cancer aka cutaneous squamous cell carcinoma (cSCC).  As a matter of fact there is a phase III trial testing keytruda for use in those with cSCC with 19 countries participating.   This is the trials offical page.


I know you'll keep an eye on more of those nasty cSCC.  My brother in law has one or 2 taken off every year.  Other than some plastic surgery to get rid of them he's good. 


All the best,
