New blood test trialled to spare unnecessary chemotherapy

October 17, 2018

A new blood test is currently being trialled at more than 40 hospitals in Australia and New Zealand to prevent cancer patients from unnecessary chemotherapy.

The circulating tumour DNA (ctDNA) test, which is developed through a collaboration between the Walter and Eliza Hall Institute of Australia, and Johns Hopkins Kimmel Cancer Centre of US, can determine if fragments of tumour DNA are present in a patient’s blood after the surgical removal of tumours.
