Test Your Biomarkers

Why Biomarkers?

Before beginning a treatment plan, it's important to ask about biomarkers. Biomarkers can help you understand what your tumor is made of, and they can also let you know what treatments you may qualify for or which treatments are unlikely to work. Many clinical trials are designed around biomarkers. Biomarkers are the backbone of personalized medicine.

Biomarkers are the backbone of personalized medicine.

Actionable biomarkers impact a treatment plan now, oftentimes there’s an FDA-approved drug associated with the biomarker.

HBV/HCV

HBV or HCV infections can impact liver cancer patients’ risk and treatment plan.

AFP

Monitoring primary liver cancer patients and predicting treatment response.

CLDN18.2

CLDN18.2-positive can make some gastric/GEJ patients eligible for targeted therapy and qualify others for clinical trials.

IDH

A mutation in the IDH gene can make cholangiocarcinoma patients eligible for targeted therapy and clinical trials.

NRG1 Fusion

A fusion with NRG1 can make pancreatic and cholangiocarcinoma patients eligible for targeted therapy and qualify others for clinical trials.

FGFR

An alteration of an FGFR gene can make some cholangiocarcinoma patients eligible for targeted therapy and qualify others for clinical trials.

HRR

A mutation in an HRR gene may make pancreatic cancer patients eligible for targeted therapy and qualify others for clinical trials.

PD-L1

High PD-L1 can make gastric/esophageal/GEJ and anal cancer patients eligible for immunotherapy and others eligible for clinical trials.

RAS

A mutation in genes like KRAS or NRAS can impact eligibility for targeted therapy.

EGFR

Metastatic colorectal and pancreatic cancer patients may be prescribed anti-EGFR therapies.

PIK3CA/mTOR pathway

A mutation in the PIK3CA gene may impact gastric and colorectal cancer patients’ treatment plans and qualify others for clinical trials.

NTRK Fusion

A fusion with an NTRK gene can make patients eligible for targeted therapy.

RET

An alteration in the RET gene can make patients eligible for targeted therapy.

HER2 (ERBB2)

An overexpression of HER2 can make patients eligible for targeted therapy and immunotherapy.

TMB

A high TMB can make patients eligible for immunotherapy.

BRAF

A mutation in BRAF V600E can make patients eligible for targeted therapy.

DPYD

A deficiency in the DPYD gene means the body lacks proteins needed to break down 5-FU or capecitabine.

HPV

There are hundreds of strains of HPV, only a few are high-risk and cause cancer. It's important for anal cancer patients to get tested.

MSI-H/dMMR

Microsatellite instability (MSI-H)/mismatch repair (dMMR) can make patients eligible for immunotherapy.

Emerging biomarkers are showing promise in clinical trials and may impact treatment plans in the future.

B7-H3

An overexpression of B7-H3 could qualify esophageal patients for clinical trials.

DAXX/ATRX/MEN1

These tumor suppressor proteins are common in pancreatic neuroendocrine cancer

MUC1

An overexpression of MUC1 could qualify patients for clinical trials.

EBV

A virus that can create a unique subtype of gastric cancer.

CTC

Evaluating cancer cells in the blood to make predictions and monitor progress.

CDKN2A/B

A mutation in the CDKN2A/B gene may qualify patients for clinical trials.

TP53

A mutation in the TP53 gene may qualify patients for clinical trials.

Wnt pathway

A mutation or overexpression in a Wnt pathway gene may qualify patients for clinical trials.

POLE / POLD1

POLE/POLD1 mutations can make patients eligible for immunotherapy clinical trials.

MET

An alteration in the MET gene can make patients eligible for clinical trials.

ctDNA

Testing the blood for evidence of cancer.

GNAS

A mutation in the GNAS gene may qualify patients for clinical trials.

TIL

Metastatic patients may qualify for TIL therapy clinical trials.

Clinical Trials

Most clinical trials exploring new cancer drugs will require biomarker testing. Clinical trials are where up-and-coming biomarkers become star players, where experimental approaches to treating a cancer become the standard-of-care. Clinical trials are truly the future of medicine. There are clinical trials available for patients of every GI cancer type and nearly every biomarker.

Biomarkers and biomarker testing

How much does it cost?

Is this the same thing as genetic testing?

What if I already started treatment?

"I wish I had known how important therapy is as soon as I heard the diagnosis. Cancer is a heavy word that's hard to carry alone."

"Work at preventing social and emotional isolation. You may need to seek out people who have also faced cancer, and therefore understand your thoughts and feelings in ways that "muggles" (people who haven't had cancer) simply cannot. Or you may benefit from talking with a professional therapist. But just don't ignore your mental health as you fight to restore your physical health."

"Looking back, I wish I had known how powerful self-advocacy could be. The early signs were there, but they were misattributed by my PCP, and I didn’t yet know how to trust my instincts or push for answers. I can’t help but wonder how things might have been different if I’d known then what I know now."

"We have the wrong idea that colorectal cancers or GI cancers only affect the older population. It's not real. We've seen the numbers. It's important to recognize the trend, and also a a patient, recognize the symptoms and advocate for yourself. If you're not being believed and taken care of, look for second opinions. "

"I tell patients: Make sure you're on a good, healthy, varied diet; avoid alcohol; don't smoke; look after your mental health, and get good sleep. The main thing I'm focused on is exercise. There are international guidelines, and if you adhere to them, you can expect more people to survive and reduction in recurrence. "
