Dr. Pranil Chandra and Dr. Luis Raez: Enabling Comprehensive Genomic Profiling in Lung Cancer
In this episode of the Precision Medicine Podcast, hosts Karan Cushman and Clynt Taylor welcome back Dr. Luis Raez, Medical Director and Chief Scientific Officer at Memorial Cancer Institute, who is joined by Dr. Pranil Chandra, Chief Genomics Officer at PathGroup. Together, we discuss the key barriers to performing comprehensive genomic profiling for cancer patients and how collaboration between oncologists and pathologists can enable a more consistent approach.

Both doctors have seen remarkable advances in the identification of driver mutations and related targeted immunotherapies in precision oncology, and yet they also recognize a persistent lag in biomarker adoption and appropriate testing.
To demonstrate this reality, Karan references the 2022 MYLUNG retrospective observational study that investigated metastatic, non-small cell lung cancer patients receiving first-line systemic therapy within a large community oncology network. The study, which occurred between April of 2018 and March of 2020, found that while most patients were tested for one biomarker, only 46% were tested for all five of the guideline-recommended markers, which include PD-L1, EGFR, ALK, ROS1 and BRAF. This was also true for next-generation sequencing.
Dr. Raez and Dr. Chandra point to several reasons for the lack of testing, including the complexity of new innovations for oncologists and healthcare disparities, and they explain some of the improvements that should be made to help close the gap between available life-extending, targeted therapies on the market today and the lung cancer patients who need them. These include:
Better coordination and collaborative communication between pathologists and oncologists to ensure the appropriate molecular tests are ordered in a timely manner. Often, they point out, the oncologist is waiting for the pathologist to order the test, and any delays can add stress for patients who are anxious for results.
Using liquid biopsy when there is not enough high-quality tissue to make a diagnosis and perform ancillary molecular testing. (Dr. Chandra notes that you need at least two to four millimeters of tissue with at least 20% tumor.)
Ensuring lab reports are easily and accurately interpreted and therefore more actionable.
Constructing faster and more flexible approaches to regulation and reimbursement.
Both doctors speak in-depth about the importance of a coordinated, multidisciplinary, institutional approach to implementing comprehensive genomic profiling, which is the standard of care in patients with advanced non-small cell lung cancer. It’s a valuable episode for anyone concerned with how slowly molecular testing is being adopted when the benefits to cancer patients are clear.
