Google files patent for breath test to detect tumors using special markers

Patent drawing
Patent drawing from the official filing.

This patent describes a method for detecting cancer by giving a patient a substance that sticks specifically to tumor cells. The substance releases a unique chemical into the blood that eventually shows up in the person's breath. Doctors can then measure this chemical in a breath sample to estimate how much tumor tissue is present.

Why it mattersIt offers a potentially less invasive way to monitor cancer progression by using a simple breath test instead of repeated biopsies or imaging.

In the filing’s own words

The present disclosure is related to methods and compositions related to detecting a tumor disease state in a subject using a sample of the subject's exhaled breath. A conjugate is administered to the subject, wherein the conjugate includes a tumor targeting moiety linked to a volatile organic compound (VOC). The presence or amount of the VOC is detected as an indication of the disease state.

What exactly they claim (claim 1)

1. A method for detecting a tumor disease state, comprising: (a) contacting a tissue of interest with a conjugate including a tumor targeting moiety linked to a volatile organic compound, wherein tumor targeting moiety has affinity and specificity for tumor cells, wherein the volatile organic compound is a non-naturally occurring volatile organic compound; and (b) measuring an amount of the volatile organic compound present in exhaled breath, wherein the amount of the volatile organic compound in exhaled breath is indicative of an amount of tumor cells present at the tissue of interest.
