cancer is changing.

Methylation-based cancer monitoring.
From a simple blood draw.

Canos OncoTrack reads cancer-associated DNA methylation in blood to track treatment response, look for residual disease and follow changes over time. Precision care for your dog, powered by epigenetics.

AT THE START

What are we starting from?

Establish a molecular baseline at diagnosis or the start of monitoring to compare with future blood draws.

DURING TREATMENT

Is the cancer signal changing?

See whether cancer-associated signals fall, persist or increase during treatment.

AFTER TREATMENT

Is there a signal to follow up?

Look for minimal residual disease (MRD) after treatment and track signals that return during follow-up.

METHYLATION-BASED LIQUID BIOPSY

Cancer changes DNA.
And the marks it carries.

Methylation is a layer of chemical marks on DNA that helps control how cells work. Cancer changes these patterns. When cells release DNA into the blood, those marks travel with it. OncoTrack reads this epigenetic signal in cell-free DNA (cfDNA).

A wider field of signals

Cancer alters methylation across many regions of DNA, creating a broad set of signals to read alongside genetic mutations.

Reach beyond mutations

Methylation-based assays have detected tumour DNA in blood samples where somatic mutations were not detectable.

Measure change over time

Repeated methylation measurements track the amount of tumour-derived DNA in blood, revealing molecular changes through treatment and follow-up.

METHYLATION IN HUMAN CANCER CARE

A stronger signal.
Measured in blood.

Human studies show methylation detecting tumour DNA beyond mutations, identifying residual disease and tracking treatment response.

GUARDANT INFINITY · AACR RESEARCH POSTER · 2023

More cancer signals detected.

In 5,045 human colorectal, lung and breast cancer samples, methylation analysis detected ctDNA in 90%. Somatic mutations were detectable in 64%.

GUARDANT REVEAL · CLINICAL CANCER RESEARCH · 2024

Find residual disease after surgery.

In a study of 342 people with resected colorectal cancer, a methylation-based assay identified recurrence with a median lead time of 5.3 months. Longitudinal sensitivity was 81% in stage II or higher colon cancer; specificity was 98.2% across 1,461 post-treatment samples.

RADIOHEAD · CANCER RESEARCH COMMUNICATIONS · 2025

Read treatment response earlier.

Among 627 people with advanced cancers receiving immunotherapy, changes in methylation-based tumour fraction were associated with survival. Molecular non-response preceded clinical progression in 209 patients, by a median of 3.03 months.
