Patient Power community member Lucy writes in, “what role does the 17p deletion play in determining the beginning of treatment?” During this Ask the Expert segment, chronic lymphocytic leukemia (CLL) expert Dr. Jeff Sharman, from the Willamette Valley Cancer Institute and Research Center and The US Oncology Network, explains how genetic mutations can influence frontline therapy and what patients with a 17p deletion should be aware of when making treatment decisions. Dr. Sharman also discusses clinical research on gene editing and CLL.

Andrew Schorr:

Lucy wrote in.  She says, given the 17p, p53 deletion what role does that play in determining the beginning of treatment for the CLL naive patient, and you were just saying probably not FCR or BR.   

There is a more subtle point though that I would jump onto, which is what factor does it play in first?line therapy.  It's not so much the agent.  Some people feel like because they've got a 17p they need to jump into treatment sooner rather than later.  

I will tell you I have several patients with 17p deleted CLL that I've been able to watch for years and years and years without treatment.  The indications for starting therapy really remain the same.  If I see somebody clearly heading towards treatment with a 17p, I may start them a little bit earlier, but again some of these folks can be watched and wait quite well.  

And so what CRISPR does is it does allow you to make very targeted genetic modifications so that you can precisely put in new genetic material sort of wherever you want it. And I think that in the context of CAR?T therapy there's now goals to make it much more off the shelf than this sort of highly manufactured thing, and that's where I would see CRISPR having the most likely early role.
