Percepta GSC evidence library

Publications and Abstracts

Percepta GSC has been clinically and analytically validated, and has shown utility through clinical utility studies and real world evidence. 

Percepta GSC was developed to up-classify as well as down-classify the risk of malignancy for patients with lung nodules when bronchoscopy is non-diagnostic. For patients with intermediate risk lung nodules, the test down-classified to low risk with a 91% NPV to help avoid additional invasive procedures and up-classified to high risk with a 65% PPV to inform next intervention steps.

BMC Pulmonary Medicine
Percepta GSC increased the number of surgical and other ablative therapies recommended when patients were re-classified from high to very high-risk of lung cancer with a higher confidence in the recommended next step. By up-classifying nodules from high to very high ROM, Percepta GSC will improve the likelihood and timeliness of appropriate therapies and assist clinicians more effectively manage patients to improve patient outcomes.
