Precision Medicine: Reaching New Levels
I’ve been
writing a lot about the Precision
Medicine Initiative because I am excited about this approach to cancer treatment,
and the advancements being made. The
National Foundation for Cancer Research (NFCR) has supported cancer research
for all cancers since 1973, and is taking a leadership role in educating the
public about how cancer treatment has less to do with the location of the
tumor, and more to do with the genetic abnormalities. Yet today, it’s still the case in most medical
care systems that cancers are classified mainly by the type of tissue or part
of the body in which they presented—breast, lung, brain, colon, etc. But thanks
to advances in scientific knowledge and DNA sequencing technology, things are
changing, and researchers are discovering that cancers that arise in totally
different parts of the body can sometimes have a lot in common. This is leading to rethinking how we approach
clinical trials.
For example,
The
NCI-Molecular Analysis for Therapy Choice (NCI-MATCH) is a phase II clinical
trial that will analyze patients’ tumors to determine whether they contain
genetic abnormalities for which a targeted drug exists (that is, “actionable
mutations”) and assign treatment based on the abnormality. NCI-MATCH seeks to
determine whether treating cancers according to their molecular abnormalities
will show evidence of effectiveness. For instance, a breast cancer patient may
have the anaplastic lymphoma kinase (ALK) gene mutation often found in lung
cancer. The NCI-MATCH Trial will look at treating the ALK mutation rather than
the type of cancer. NIH Director Dr. Francis Collins has also commented “so it
may be that somebody who has a lung cancer has more in common with somebody
with a bladder cancer than two people with lung cancer.” In all, more than 20
different study drugs or drug combinations targeting specific gene mutation
will be used in the NCI-MATCH Trial as treatment for each particular gene
mutation.
These
findings provide yet another example of how cancer research has been leading
the way in precision medicine. Still, much more remains to be done. As part of
the new Precision Medicine Initiative, researchers will explore fundamental
aspects of cancer biology, and seek to understand the mechanisms of drug
resistance. NFCR will continue to support research that will accelerate the
design and testing of more precisely targeted cancer treatments, including
combination therapies. I am grateful for
the continued public support for the important research being done by NFCR-supported
cancer researchers. #Gratitude
