Though biomarker testing in early-stage non-small cell lung most cancers has improved, some sufferers nonetheless don’t obtain full, guideline-recommended testing, in keeping with Dr. Sandip Patel, a professor of Medical Oncology at College of California, San Diego (UCSD), who added that this factors to a niche between medical trial practices and on a regular basis care.
He sat down for an interview with CURE to debate findings from a real-world research of biomarker testing in early-stage resected non-small cell lung most cancers within the U.S. These information have been shared at IASLC 2025 World Convention on Lung Most cancers and investigated how testing in on a regular basis follow compares with medical trials.
At UC San Diego Moores Most cancers Heart, Patel additionally serves because the chief of Experimental Therapeutics, deputy director of the Sanford Stem Cell Scientific Heart, co-leader of Strong Tumor Therapeutics, and medical director of Scientific Analysis Informatics.

What prompted you to discover real-world information on biomarker testing in early-stage lung most cancers?
Traditionally, medical trials checked out biomarker testing. That is actually the tip of the iceberg. Most of oncology follow is sort of ‘underwater,’ within the sense that we do not see what occurs, and real-world proof is the best way for us to sort of peer into that ocean a bit. What’s finished in a medical trial or what’s finished in a printed report may be very completely different than what’s seen in actual follow.
We take a look at a Flatiron database on real-world testing in non-small cell lung most cancers. More and more, as you talked about, precision oncology strategies have moved from simply the metastatic setting, the place they continue to be essential, to now more and more within the early-stage setting the place we’re attempting to maximise treatment charges or no less than maintain off relapses so long as potential. These precision strategies and people DNA assessments and immune staining stay crucial, for instance, for PD-L1 testing for EGFR, ALK and ROS1, on the very least.
We wish to see what real-world follow was like, since that’s the place most sufferers are handled, locally setting. And we discovered that over time, there’s been enchancment in testing charges, together with in early-stage illness. However I feel we will do extra, and there are most likely about 10 to fifteen% or 20% of sufferers that aren’t getting the complete, applicable testing within the curative-intent setting.
Attempting to know why and the way we may help these sufferers is the following step to ensure that we will supply these therapies for sufferers. As a result of if now we have focused remedy of immunotherapy, you’ll be able to solely use focused remedy successfully if you happen to search for the goal.
We do not wish to be guessing; we wish to be testing. We wish to do that within the metastatic setting and within the early-stage setting. We wish to discover these obstacles. Are they monetary obstacles? Are there logistical obstacles? Are there practice-based obstacles to get the check finished? As a result of as soon as we perceive these issues, we may help that final group be sure that to get the precision oncology therapies they deserve within the early-stage setting as nicely.
