Caris Life Sciences Unveils Study on Next-Gen Sequencing in Cancer

Caris Life Sciences® (Caris), an innovator in the realm of precision medicine and AI-driven biotechnology, has published a substantial study emphasizing the pivotal role that next-generation sequencing (NGS) plays in evaluating microsatellite instability (MSI) and mismatch repair deficiency (dMMR) in solid tumors. This study, featured in the prestigious journal JCO Precision Oncology, is grounded in the examination of over 190,000 cancer cases and stands as a beacon of research clarity in a field often clouded by complex methodologies.

The research presents compelling evidence demonstrating the high concordance rate between the NGS assessment of MSI (NGS-MSI) and the immunohistochemistry analysis of mismatch repair (IHC-MMR) across various cancer types. This finding underscores the potential of NGS not merely as a viable alternative but perhaps a superior method for determining therapeutic strategies for patients, particularly those eligible for immune checkpoint inhibitors (ICIs).

The Significance of MSI and dMMR

High MSI (MSI-H) and dMMR are crucial biomarkers in oncology that help pinpoint patients likely to benefit from ICIs, which have transformed cancer treatment paradigms. Detecting dMMR can be particularly challenging, as traditional methods may overlook certain cases. The Caris study highlights the ability of NGS to unveil issues related to defectiveness in MMR—a critical insight considering the role of dMMR in fostering genetic mutations that contribute to cancer proliferation.

According to Dr. George W. Sledge, Jr., Executive Vice President and Chief Medical Officer at Caris, this study addresses a vital concern in oncology: the best approach for accurately assessing MMR. By harnessing their extensive clinico-genomic database, Caris has brought to light that NGS not only matches the accuracy of IHC-MMR assessments, but also reveals additional actionable biomarkers that can inform treatment plans. The comprehensive molecular profiling enabled by NGS allows for more informed therapeutic decisions tailored to individual patient profiles.

Rigorous Study Design

The study's design is robust, encompassing 191,767 tumor samples subjected to rigorous testing, enabling a thorough investigation into the accuracy of both methods. The result? A mere 0.31% rate of discordance between NGS-MSI and IHC-MMR results. This finding illustrates the reliability of NGS in clinical settings and its potential to improve patient outcomes through more accurate diagnostics.

Moreover, Dr. David Spetzler, President of Caris, emphasized that while neither NGS nor IHC can capture every dMMR case, the research underscores the necessity of NGS for comprehensive molecular profiling to not only identify eligibility for ICIs but also for other targeted therapies.

Insights Beyond MMR

The study did not stop at evaluating MMR status; it also delved into the broader implications of tumor characteristics linked with immunotherapy responses. For instance, tumors categorized as dMMR/MSI-H consistently showcased improved overall survival post-immunotherapy compared to their MMR-proficient counterparts. Additionally, the presence of a high tumor mutational burden—another significant biomarker for immunotherapy efficacy—was more frequently seen in patients presenting with dMMR/MSI-H tumors. These findings further support the role of NGS in personalizing cancer therapies based on unique tumor profiles.

Regulatory Advances and Future Implications

In a further testament to its innovative approach, Caris recently secured FDA approval for MI Cancer Seek™, the first diagnostic tool combining whole exome sequencing (WES) and whole transcriptome sequencing (WTS) with FDA-sanctioned indications for various therapies. This remarkable tool not only assesses MSI status with precision but also offers optional add-on tests, enhancing the landscape of molecular profiling in oncology.

As they continue to blaze trails in cancer research and diagnostics, Caris Life Sciences remains anchored in its mission to realize the full potential of precision medicine, aiming to improve patient care and outcomes across the globe. Headquartered in Irving, Texas, and renowned for their commitment to diversity and inclusion, Caris exemplifies leadership in the health tech industry domestically and internationally.

In conclusion, the findings from Caris Life Sciences’ study provide a powerful endorsement for NGS technology in cancer diagnostics, heralding a future where personalized treatment plans become the standard of care in oncology. With their ongoing commitment to innovation, Caris may indeed be shaping the next frontier in cancer therapies.
