Study summary

The pathological anatomy laboratory, which is managed by the IPG, would involve monitoring patients being treated for cancer and receiving care at the GHDC in order to take blood samples from those in whom the presence of plasma ctDNA carrying a mutation in a specific gene is suspected - a mutation detectable by the TST79 test.

Read the detailed description

The development of targeted therapies in oncology requires the regular implementation of new tests. Routine clinical analyses currently focus mainly on tumour tissue, but analyses of blood components - particularly plasma - or other biological fluids from patients with cancer are gaining clinical significance in light of advances in molecular biology techniques and knowledge in oncology.

The laboratory wishes to offer patients with cancer sequencing of circulating free DNA (ctDNA) in plasma using a commercial test developed by Illumina. This test can detect various types of mutations (point mutations, small deletions or insertions, loss or gain of gene copy number, and gene fusions) in 79 genes (TST79 test).

What researchers measure

Primary outcomes

  1. To validate and accredit the TST79 test on plasma samples within the hospital's pathology laboratory

    The aim is to extend tumour DNA sequencing to circulating tumour DNA (ctDNA), which is present in the plasma of cancer patients.

    Time frame: Through study completion, an average of two years
