Revolutionizing Lung Cancer Detection with NeXT Personal Test
Revolutionizing Lung Cancer Detection with NeXT Personal Test
In an exciting advance for lung cancer diagnostics, Personalis, Inc. (Nasdaq: PSNL), alongside luminaries such as Professor Charles Swanton and researchers from the Francis Crick Institute in London, has introduced significant findings from their TRACERx lung cancer study. This critical research was recently published in the well-respected journal, Nature Medicine, marking a pivotal moment in cancer detection.
The Breakthrough NeXT Personal Test
The NeXT Personal test is specifically designed to identify small traces of circulating tumor DNA (ctDNA) in the bloodstream of patients dealing with cancer. This ultra-sensitive personalized test reveals the increasing capabilities of modern technology in accurately diagnosing conditions at earlier stages. In a cohort of 171 early-stage non-small cell lung cancer (NSCLC) patients, the NeXT Personal assay showed remarkable results, revealing its high sensitivity in detecting various lung cancer subtypes that have historically been elusive in blood analysis.
Effective Detection of Lung Adenocarcinomas
Among the remarkable findings, the NeXT Personal test achieved a perfect detection rate of 100% in non-adenocarcinomas and an impressive 81% in lung adenocarcinomas (LUAD). These advancements provide hope and improved diagnostic capability, particularly in cases where ctDNA is produced in minimal amounts, which many prior methods have struggled to capture.
Clinical Implications for Early-Stage Patients
The study's findings suggest a potential paradigm shift in the management of lung cancer. The data revealed that the levels of ctDNA observed before surgical intervention were significant in predicting overall survival rates for early-stage LUAD patients. Those patients who tested negative for ctDNA before surgery boasted a remarkable 100% five-year survival rate, whereas those with positive tests faced a heightened risk of relapse during the same timeframe.
Understanding Minimal Residual Disease (MRD)
Moreover, even patients with the thinnest traces of cancer DNA—below 80 parts per million (PPM)—exhibited a substantial risk for recurrence. This finding underlines the importance of employing ultra-sensitive MRD testing methods like NeXT Personal as part of a comprehensive approach to lung cancer care.
Insights from Industry Experts
Dr. Charles Swanton emphasizes that this study illustrates the vital role of sensitive ctDNA tests like NeXT Personal in lung cancer detection. With each advancement, personalized treatment becomes increasingly achievable, further optimizing clinical benefits for patients undergoing therapy. Richard Chen, MD, MS, who serves as the Chief Medical Officer and Executive Vice President of R&D at Personalis, elaborated on the design intent for NeXT Personal, aimed at detecting cancer resurgence or remnants at their earliest stages.
The Future of Lung Cancer Management
Anchored in its promises, the ongoing collaboration between Personalis and the TRACERx team seeks to expand the understanding of ctDNA testing's clinical efficacy. This continuous evolution forms a crucial basis for seeking Medicare coverage for NeXT Personal Dx solely for lung cancer cases.
About Personalis, Inc.
At Personalis, we are at the forefront of cutting-edge cancer management, employing breakthrough personalized testing methodologies. Our target is to reshape the landscape of cancer care, providing a guiding hand from biopsy and throughout the entire patient journey.

The Scope of Cancer in the U.S.
Lung cancer, recognized as the second most frequent cancer in the U.S., demands constant attention, with projections suggesting approximately 238,340 new cases and 127,070 deaths in the current year. The high recurrence rates associated with even early-stage cases underscore the necessity for effective diagnostic tools such as the NeXT Personal test.
