Dr. Mok on Plasma Testing Approaches in Lung Cancer

Published: Friday, Aug 09, 2013

Tony S.K. Mok, BMSc, MD, FRCPC, Professor, Department of Clinical Oncology, Chinese University of Hong Kong, Prince of Wales Hospital Hong Kong, China, discusses different plasma testing approaches for patients with lung cancer.

Mok says that a physician has the option to conduct a plasma test when the diagnosis is being made. By the time the lung cancer diagnosis is confirmed, a physician will have plasma testing results available. If the test is positive, treatment can begin, but if it is negative, a physician can subject the tumor for testing.

If good tissue cannot be obtained for testing, a physician can use plasma as a testing method but should be aware that sensitivity is only 76%.
