Cancer treatment is increasingly driving costs for employers, particularly as pandemic-related screening delays are leading to increases in later-stage cancer diagnoses. Corporate benefits managers not only have to balance organizational costs with adequacy of coverage but must also decide which new diagnostic tools and treatments will be covered by their plans. Getting it right can mean the difference between life and death for cancer patients, but how is an HR leader supposed to keep up with the rapidly changing science behind modern cancer treatment?

The Employers’ Prescription for Employee Protection Toolkit: Best Practices for Biomarker Testing Coverage is designed to help benefits managers, human resources professionals, and executives better understand the increasing role and importance of biomarker testing in cancer treatment. Biomarker testing is central to treatment planning for a growing number of cancer types and sub-types, leading to more effective targeted treatments, avoidance of ineffective and potentially harmful treatments, and improved outcomes for patients.

What's Included

Section 1 explains the basics of biomarkers, their role in guiding treatment decision-making, the biomarker testing landscape, and the current gaps in biomarker testing coverage, which can lead to sub-optimal treatment plans and outcomes among populations already struggling with healthcare disparities.

As CancerCare continues its life-defining work to meet the needs of people facing a cancer diagnosis, we recognize that recent scientific and clinical breakthroughs in cancer treatment present both hopeful progress and practical challenges. This dichotomy is especially acute when it comes to precision oncology: the variability of individual cancers even among tumor types and the availability of increasing numbers of targeted cancer treatments designed to attack specific aspects of an individual’s disease.

While these treatments offer real hope to people with cancer, they are predicated on timely and comprehensive tests to identify the biomarkers that indicate which treatments are best for them. Unfortunately, many insurance plans do not cover appropriate and comprehensive biomarker testing, which creates a real risk that patients will not receive the most effective therapy, and instead receive sub-optimal treatment, or even treatment that could cause them harm. The human and economic costs of these delays and gaps in care are significant.

As a supplement to CancerCare’s landmark Employer Toolkit focused on best practices for prescription drug benefit design, we are pleased to offer this Employer Toolkit on Biomarker Testing, to help those involved in benefit design make optimal decisions about covering cancer biomarker testing for their employees. Our recommendations reflect best practice policy models that rely on evidence-based guidelines put forth by independent, expert organizations to determine appropriate testing coverage.

Healthcare benefit design is critical to ensuring that cancer patients have timely access to the right care at the right time. We hope you will find this toolkit useful as you develop meaningful and cost-effective coverage policies for your employees.

Biomarkers and Biomarker Testing

The oncology treatment landscape is more dynamic and precise than ever, with new scientific and clinical discoveries happening at a breathtaking pace.

alt textResearch continues to demonstrate the positive impact of precision medicine on patient outcomes, which relies on testing to identify how specific biomarkers within a person’s tumor can respond to precisely targeted treatments. Timely and open access to this type of tumor testing enables clinicians to determine the optimal treatment plan for each patient, which may include enrollment in a clinical trial.

Biomarker testing has been required or recommended for most of the cancer drugs introduced since 2017. Today there are many kinds of biomarker tests that are proven to help guide treatment decisions for a range of different cancer types, with new versions being rapidly developed. Many experts believe we are quickly moving toward a time when every cancer patient should have biomarker testing at diagnosis and recurrence to help guide treatment decision-making.

Importantly, despite the clear connection between biomarker testing, precision medicine, and improved treatment outcomes, insurers often do not provide adequate coverage. Although many commercial self-insured/large-group employers provide some coverage, policy terms vary since there are currently no consistent minimum coverage requirements for biomarker testing. Consequently, many patients are denied the benefits of these critical diagnostic tools. Furthermore, barriers to testing access can exacerbate health inequities, leading to sub-optimal treatment plans and outcomes among populations already struggling with healthcare disparities.

To maximize opportunities for the best and most equitable care and access to appropriate treatment, CancerCare calls on employers and administrators of self-insured/large group health plans to insist on coverage that ensures their members and beneficiaries have access to timely, guideline-recommended biomarker testing and optimized oncology treatment plans.

This Toolkit is designed to help employers understand the role and benefits of cancer biomarker testing, so they can ask the important relevant questions of their consultants and third-party administrator or healthcare insurance provider, avoid coverage provisions that could negatively impact covered employees, and design coverage that best meets the needs of their employees. A glossary of key terms is included. We've also developed a biomarker testing fact sheet for patients.

Cancer and Mutations

Cancer is a disease in which certain cells grow uncontrollably and can spread to other parts of the body. It is caused by DNA changes to genes that control the way a cell functions, especially how it grows and divides. Biomarkers are specific gene mutations that may indicate important characteristics of the cancer, including how it may grow and spread, its sub-type, and if or how well the patient may respond to a particular treatment. (See glossary for more terms.)

Precision Treatment Through Biomarker Testing

alt textPrecision medicine in oncology has dramatically changed the way cancer is diagnosed and treated thanks to advances like the sequencing of the human genome and more cost effective genome sequencing technologies. Continued technological advances in DNA sequencing tools make them faster and cheaper to use and are leading to much more precise cancer diagnoses and treatments that can effectively target specific molecular sub-types of cancer1.

The list of cancers with clinically valid biomarkers includes many common cancers like lung cancer, breast cancer, melanoma, and colorectal cancer, as well as rare cancers like bile duct cancer2. Fueled by continual advances in research, this list is rapidly growing.

Although cancers are often defined by where in the body they occur, many new treatments effectively target cancers based on specific biomarkers, rather than the tumor’s location. Targeting biomarkers has led to significantly more effective cancer treatment with fewer side effects for patients. Precision cancer treatments include targeted therapies (aimed at specific traits of cancer cells) and biomarker-guided immunotherapy treatments that help a patient’s immune system fight their cancer 1, 2.

Case Study

     Juanita Segura
     East Chicago, IN
     Lung Cancer
     Watch Juanita's story »

When the wheezing started in June 2014, Juanita Segura was a 45-year-old mother of five in East Chicago, Indiana. A couple of months later, she developed a cough, and her primary care physician treated her for asthma symptoms. In September, Juanita had a chest x-ray and bloodwork to rule out pneumonia and was started on a course of prednisone.

After two additional months of worsening symptoms, Juanita saw a pulmonologist. Her new doctor noticed an enlarged lung on her x-rays. He gave her a new drug but five days later a very sick Juanita was at the ER, where she had more tests. The stumped doctors finally landed on a possible diagnosis – an infection acquired from her tropical bird – and she was sent off to another specialist. When the bird was found not guilty, Juanita pushed for a CT scan.

The scan showed fluid in her lungs and Juanita was admitted to the hospital. She had a bronchoscopy and two days later was diagnosed with stage 3 malignant lung cancer. Juanita’s husband Steve kicked into high gear, researching treatments and facilities, and took Juanita to Chicago for a second opinion. Steve had read about biomarker testing and the doctors at the cancer treatment center agreed that she should be tested but were unable to get an adequate tissue sample immediately. While they waited, Juanita started chemotherapy and radiation treatments that proved to be ineffective. Six weeks after her initial diagnosis, Juanita learned that her cancer was positive for the ALK biomarker – a mutation for which there are effective targeted therapies. She was prescribed a therapy that targets the ALK mutation, but her employer-based insurance company denied coverage. Juanita appealed and although she won, the start of that treatment was delayed by the insurance company’s prior authorization requirement and her need to appeal the denial.

Juanita’s biomarker testing identified a tumor mutation that was known to be treatable by the targeted therapies that saved her life. Two years after her diagnosis, Juanita Segura opened her own CrossFit Gym, setting an example of fortitude and courage for her clients. “Even if you have a diagnosis, it shouldn’t stop you,” she said. “It’s not going to stop me,” and it hasn’t.

Juanita is now eight years into her cancer experience and taking her 4th targeted treatment. She and Steve are planning a trip to Greece and expecting their second grandchild. Without biomarker testing, Juanita would have suffered through ineffective chemo and radiation and would not have lived to meet even her first grandchild.

Biomarker Testing

Biomarkers are identified through biomarker testing, sometimes referred to as molecular profiling and genome sequencing3.

Multiple types of tests are available to identify the specific characteristics of a patient’s cancer, with the goal of identifying the best treatment4

  • Some tests check for a single biomarker (single analyte tests), while others look for many biomarkers at the same time (panel test).

  • Some tests are focused on a certain type of cancer (e.g., lung cancer, breast cancer, or melanoma), while others are focused on individual biomarkers that can be found in multiple types of cancer (e.g.,
    BRAF mutations).

  • Next Generation Sequencing (NGS) looks at all the DNA (within and outside of genes) in the cancer.

  • Some biomarker tests evaluate tumor tissue from a surgical biopsy of the cancer. A new class of biomarker tests, known as liquid biopsies, is designed to evaluate blood or other fluids to identify cancer biomarkers.

Biomarker Testing Landscape

The landscape for biomarker testing in cancer is rapidly evolving as new discoveries are made and new technologies are developed. Once a biomarker has been identified, it is necessary to have a reliable test that can accurately measure it within an individual’s cancer5.*

In the United States, biomarker tests are subject to multiagency regulatory oversight. Those used to select an appropriate therapy are called companion diagnostics. Evidence from clinical trials is used to demonstrate that these tests can identify the biomarker and that the therapy is safe and effective for the patients with that biomarker6. Companion diagnostics require review by the FDA at the same time as a related new drug.

US clinical laboratories develop their own biomarker tests under a different set of rules, overseen by the US Centers for Medicare and Medicaid Services (CMS) and a framework known as CLIA (Clinical Laboratory Improvement Amendments). These types of tests are referred to as Lab-Developed Tests or LDTs. Both types of tests are important to clinicians and patients in making the most appropriate decisions about cancer treatment.

*There are multiple concepts that are evaluated within the healthcare system (especially among researchers, clinicians, regulators, and payors) to determine whether a certain test is reliable for use. These are known as Analytical Validity, Clinical Validity, Clinical Utility.

Biomarker Testing to Guide Cancer Treatment

In today’s oncology clinical practice, timely information about cancer biomarkers is central to treatment planning for a growing number of cancer types and subtypes. A vast majority of oncologists (89%) surveyed in 2021 said biomarker testing makes it easier for them to make more informed treatment recommendations, and 85% agree that improving access to biomarker testing and subsequent treatment informed by biomarker testing is important for advancing health equity7.

Evidence is rapidly mounting that biomarker testing and biomarker-directed therapy improves outcomes for patients8.

“Access to biomarker testing is an important health equity issue. For certain populations, biomarker testing is routine and a game changer for the course of their cancer, while other populations, for a variety of reasons, are not able to equally access this potentially life-saving tool.”

--Jan Kitajewski, PhD
Director, University of Illinois Cancer Center

alt textLung cancer is the leading cause of cancer death worldwide and has been extremely difficult to treat. With the help of biomarker testing, targeted treatment, and immunotherapy, survival rates have soared, providing much encouragement to patients, clinicians, and researchers. A large study of lung cancer patients in Thailand10 shows the impact that targeted treatment can have on survival.

Chart adapted from a comprehensive update from the Srinagarind Hospital-Based Cancer Registry from 2013 to 2017. Asian Pacific Journal of Cancer Prevention, 22(8), 2501–2507.10

Such positive impact from precision oncology is also seen among other cancer types, including melanoma, breast cancer, and colorectal cancer.

  • A 2021 study among people with a variety of rare sub-types of cancer found that administering biomarker testing and targeting treatments could improve outcomes for patients with poor prognoses. In this study, patients were given therapies based on their tumor’s profile, before any other (likely ineffective and toxic) generalized therapies were administered, thereby creating efficiencies in treatment, and preventing side effects.11

Case Study

     Breast Cancer
     Watch Rebecca's story »

alt textRebecca was 29 years old when she found a lump in her breast and was diagnosed with Stage 2 breast cancer. Given her family’s extensive history of cancer, including an aunt and grandmother who died from breast cancer, she thought her diagnosis was a death sentence.

What Rebecca didn’t know was that her care team had sent her tissue samples out for biomarker testing, a step that would ultimately save her life. A month after her initial diagnosis, Rebecca learned that she had HER2-positive breast cancer, a cancer subtype that is susceptible to very effective targeted treatments. Rebecca was treated with six cycles of a targeted chemotherapy before having a double mastectomy. She was then prescribed a year of immunotherapy, a treatment that uses a person’s own immune system to fight cancer. Rebecca’s insurance, which she receives through her husband’s employer, would only pay for six months of immunotherapy, which meant she had to find financial assistance in the form of copay cards to help pay for her treatment.

Five years after her diagnosis, Rebecca has no signs of disease, was able to complete a master’s in public health, and is currently pursuing her EdD in Education. It’s a far different outcome from what might have been had she not had biomarker testing. Without the information that the biomarker testing provided, Rebecca’s treatment would have included “one-size-fits-all” chemotherapy with uncertain effectiveness for stopping the growth of her cancer and significant negative side effects that would have impacted her quality of life.

Rebecca was lucky. She benefited from the advances in biomarker testing to pinpoint mutations in the cancer, and enabled her clinicians to deploy treatments specific to those mutations. But many insurance plans still limit the use of biomarker testing, leaving patients and doctors without key information to decide which treatments will work best.

Guidelines for Coverage

By relying on the objective review of available data, clinicians, patients, and insurers can make the best decisions about coverage and treatment choices. Using evidence-based clinical treatment guidelines ensures that testing and treatment decisions reflect the latest knowledge of a cancer and its biomarkers.

Several highly regarded professional associations, including the National Comprehensive Cancer Network (NCCN), the American Association of Clinical Oncology (ASCO), and the College of American Pathologists (CAP) have developed biomarker testing and treatment guidelines. Insurers and employers should mandate the reference of these organizations in their policies, ensuring that what is recommended in their guidelines is covered and can be accessed in a timely way by covered persons with a cancer diagnosis.

  • In rectal cancer, a very difficult rare cancer, data from a small study released in 2022 found that using immunotherapy for patients with a specific biomarker prior to their surgery could be curative. Every patient in the study had a complete response to the therapy, preventing the need for more toxic treatments over time12.

  • A 2015 study comparing the impact of targeted therapy in various metastatic cancers found that patients who received targeted therapy had significantly improved outcomes when compared with those who were treated with traditional therapies9.

A particularly challenging aspect of many advanced stage tumors is their ability to change (or mutate), developing ways to resist initial therapies. For this reason, it is often important to conduct repeated biomarker testing throughout a patient’s continuum of care. This can help clinicians tailor the most effective treatment approaches34.

“Patients with certain mutations in their cancer can now be treated with ‘targeted therapies,’ which can be more effective than traditional chemotherapies. But if patients can’t get biomarker testing because of insurance coverage or other barriers, they may be denied the most appropriate and effective treatments available.”

Coverage and Reimbursement Gaps for Biomarker Testing29

alt textIn 2018, the US Centers for Medicare and Medicaid Services (CMS) determined that Next Generation Sequencing (NGS) is a diagnostic laboratory test that is reasonable and necessary in specific circumstances30.

However, despite the potential for significantly improved outcomes with the use of biomarker-directed treatments, many cancer patients are still not receiving this testing. One reason is that, while private payers insure more than two thirds of the US population, many health insurance policies do not yet adequately cover guideline recommended tests. There are various reasons for these coverage gaps19 as payers use different approaches in making coverage decisions31. Evidence from an FDA approval is generally the most significant determinant of coverage. For LDTs, payers often look to professional guidelines and clinical trial data to determine whether the test result is clinically meaningful and useful.

A patient survey completed in 2020 indicated that 29% of patients did not have testing done due to lack of insurance coverage or because they could not afford the out-of-pocket costs18. Lack of access to biomarker testing and coverage barriers are issues for many patients but appear to have a greater impact among racial and ethnic minorities and socioeconomically disadvantaged patients17. In the specific case of Non- Small Cell Lung Cancer (NSCLC), the most common type of lung cancer, despite the availability of extremely effective biomarker-directed therapies, up to one-fourth of these patients don’t receive biomarker testing to determine whether a specific available treatment might work for them.

alt textIn a 2021 survey, two-thirds of oncologists reported that their patients face significant or moderate insurance barriers in accessing biomarker testing, and almost half of these healthcare providers reported needing to “often” or “always” seek prior authorization from insurers before they could proceed with appropriate testing for their patients7.

In general, even when insurance coverage exists for recommended biomarker testing, health plans often require significant out-of-pocket cost sharing and prior authorization, which can add hurdles and delays to a patient’s access to this needed care.

These barriers have not gone unnoticed. At the state level, as of January 2023, nine states have already passed laws requiring health plans to cover biomarker testing and limiting the use of prior authorization on biomarker testing; several other states are currently considering similar legislation with more expected to follow20.

Biomarker Testing Can Reduce Costs

Biomarker testing can ensure that patients receive therapies from which they are most likely to benefit while avoiding treatments that are unlikely to be effective or could cause harm22. In this way, biomarker testing can potentially limit costs to the healthcare system, insurers, and employers.

“In the age of precision oncology, pathologists need to be thinking about constantly. Biomarkers can be part of making the correct cancer diagnosis, deciding the best cancer treatment, or both!”

--Sarah E. Kerr, MD
Pathologist, Hospital Pathology Associates, Divisions of Cytopathology, Gynecologic and Molecular Pathology, Allina Health Laboratories, Allina Health Cancer Institute

There are multiple examples of this important benefit:

  • A 2020 study evaluating the use of biomarkers to direct targeted maintenance therapy for certain ovarian cancer patients found it could yield significant savings23.

  • A 2015 study found that treatment based on testing for key biomarkers in NSCLC patients is more cost effective than failing to use biomarker testing and treating these patients with chemotherapy24.

  • A 2012 study of metastatic colorectal cancer revealed that using an identified biomarker to direct treatment decisions can ensure that only those patients who may benefit from a treatment receive it, while avoiding unnecessary costs and harm to those unlikely to benefit. This study found that it is possible to increase expected overall survival while saving approximately $7,500 per patient when compared to using non-biomarker-directed treatment25.

  • It has been estimated that using specific biomarker testing could save more than $600 million by ensuring that only those metastatic colorectal cancer patients likely to benefit from a specific therapy would receive it26.

  • A 2007 study of early-stage breast cancer patients with certain characteristics found that using a validated biomarker to guide treatment decisions could lead to more than eight years of increased quality-adjusted survival while significantly reducing overall financial costs. In this study, biomarker-guided therapy was estimated to save over $1,000 per life year- spared when compared with traditional chemotherapy27.

alt text
It has also been demonstrated that including guideline recommended biomarker testing in a benefit design is not expensive for payers. Studies of the potential cost for expanding coverage of biomarker testing among various types of insurance indicate an extremely small per member/per-month impact21.

Of course, beyond the economic value offered by biomarker testing, the human impact is enormous. For patients with a treatable cancer mutation, timely biomarker testing can literally mean the difference between life and death.

“Biomarker testing makes a huge difference in how I treat patients diagnosed with lung cancer. Getting patients on the right treatment at the right time can extend their lives by years. Every patient with lung cancer should be able to access this important diagnostic tool.”

Case Study

     Nanci Carney
     East Silver Lake, NH
     Watch Nanci's story »

In April 2021, Nanci noticed an unusual mole under her arm while showering. She knew she’d not seen it before and as a longtime volunteer with the American Cancer Society, she knew she should get it checked out. She was able to get an appointment with a dermatologist relatively quickly and was surprised when the doctor told her he would remove the mole immediately and send it off for a biopsy.

Two weeks later, when her dermatologist called at 8:30 PM on a Friday night, she knew it wasn’t going to be good news. He asked if she knew what melanoma was, and Nanci’s cancer journey began.

Nanci had surgery to remove the mole and the area around it to be sure that all the cancer had been removed. The good news was that there was no sign of spread in the tissue samples. The traditional next step would be another surgery to remove lymph nodes in the surrounding area to ensure that the cancer hadn’t spread to her lymphatic system.

Nanci’s doctor was hesitant to do the second surgery because removing those lymph nodes very often leads to lymphedema, a serious long-term condition that causes swelling due to a build-up of lymph fluid in the body. Instead, he recommended biomarker testing, which would tell them more about Nanci’s particular cancer, the chances of it recurring, and help them determine whether additional surgery was the best course.

Nanci thought she had good health insurance through her employer, and her doctor had been told by the plan’s insurance representative that they covered biomarker testing. Tissue samples from Nanci’s surgery were sent to the lab, and she soon received the great news that her cancer was unlikely to recur, and she would not need to undergo the additional surgery with a high risk of life-long complications.

A month later, despite their having told her doctor that it was covered, Nanci’s insurance company denied coverage for the biomarker testing and said she was responsible for the entire $8,500 bill. They claimed the testing was not medically necessary. Even though the biomarker testing spared Nanci from a second surgery that would have cost far more than the test, her insurer stated, “there is no proof, or not enough proof, that this test improves health outcomes.”

In reality, however, biomarker testing not only improved Nanci’s health outcome by sparing her unnecessary surgery with a high risk of later complications, but it also saved the insurance company the cost of that surgery and any treatments that may have followed had she developed lymphedema.

Covering Biomarker Testing in Plan Design

CancerCare calls on employers to insist that health coverage for their employees provides access to approved and recommended biomarker testing at diagnosis, transition in treatment plan, cancer recurrence, and any time other testing shows significant changes in the cancer or its impact on the patient.


Coverage should follow guideline recommendations and FDA-approved uses.

  • Payers should provide coverage for multi-gene panel testing as indicated by expert guidelines, and in cases where its use is more efficient than single-gene tests, a single gene test does not exist, or when tissue availability is too limited for use of multiple single gene tests.
  • Payers should cover as wide a range of tests as possible, including biomarker tests, next generation sequencing (NGS), companion diagnostics, and lab-developed tests as indicated by guidelines and FDA approvals.
  • Coverage should be extended to testing that can be used to inform clinicians and patients of potential clinical trial opportunities.
  • Coverage should be updated as new tests are approved by the FDA or added to expert guidelines. There should not be a waiting period before coverage takes effect.

Coverage should ensure access to biomarker testing at time of diagnosis and/or recurrence.

  • Coverage of biomarker testing should not be restricted to a single occurrence. It should allow for additional testing to identify a change in the genetic makeup of the patient’s cancer or to monitor disease progression.

Coverage should be comprehensive.

  • Payers should provide coverage and access to appropriate services for expert interpretation of biomarker tests, including from out-of-network experts, with no or minimal cost-sharing.
  • Coverage should extend to genetic testing for inherited risk (and familial links) and genetic counseling.
  • Coverage should include psychosocial counseling as needed.
  • Coverage of biomarker testing should not be limited to specific cancer types or stages.
  • Consider offering navigation and psychosocial support to covered employees and other beneficiaries with cancer to help secure coverage for biomarker testing and related services.

Barriers to coverage should be minimized.

  • Coverage should avoid barriers to physician ordering and patients undergoing timely biomarker testing such as prior authorization, referral restrictions, and denials that are likely to be overturned on appeal.
  • Payers should avoid burdensome cost-sharing that could impede equitable access to biomarker tests. Any cost-sharing should be via a flat co-payment, rather than percentage-based co-insurance.

What Are Biomarkers?

What are biomarkers and what do they have to do with cancer treatment? This short video explains the basics of biomarkers, biomarker testing, and how this information can lead to more effective targeted treatments.

Juanita's Story

Juanita’s biomarker testing identified a tumor mutation that was known to be treatable by the targeted therapies that saved her life. Two years after her diagnosis, Juanita Segura opened her own CrossFit Gym, setting an example of fortitude and courage for her clients. “Even if you have a diagnosis, it shouldn’t stop you,” she said. “It’s not going to stop me,” and it hasn’t.

Nanci's Story

Biomarker testing allowed Nanci’s doctors to predict how likely her melanoma was to return and avoid additional surgeries. Even though this information allowed Nanci to avoid unnecessary treatment, her insurance company refused to pay for it.

Rebecca's Story

Biomarker testing allowed Rebecca to get personalized cancer treatment that helped her beat breast cancer, and now she’s thriving. But she’s committed to advocating on behalf of her friends and family who weren’t able to get the care they needed.

Glossary of Terms

Analytical Validity, Clinical Validity, Clinical Utility
Analytical validity describes how accurately and reliably the test detects and measures a biomarker of interest. Clinical validity provides some insight into how well the test relates to the clinical outcome of interest, e.g., response to therapy, survival, etc. Clinical utility describes whether the results of the test provide information that can contribute to and improve current optimal management of the patient’s disease.33

Biomarkers are defined characteristics in the body that are measured as indicators of health, disease, or a response to an exposure or intervention, including treatment. Biomarkers can help diagnose a disease, or predict future disease severity or outcomes, like measurements of blood pressure as an indicator of cardiovascular risk or measurements of blood sugar in diabetes. Biomarkers also are used to identify the best treatment for a patient, to monitor the safety of a therapy, or to find out if a treatment is having the desired effect on the body.5

Biomarker Testing
Biomarker testing is a way to look for genes, proteins, and other substances (called biomarkers or tumor markers) that can provide information about a cancer. Each person’s cancer has a unique pattern of biomarkers. Some biomarkers affect how certain cancer treatments work.34

Clinical Laboratory Improvement Amendments (CLIA)
The Clinical Laboratory Improvement Amendments of 1988 (CLIA) regulations include federal standards applicable to all US facilities or sites that test human specimens for health assessment or to diagnose, prevent, or treat disease.35

Companion Diagnostic
A companion diagnostic test provides information that is essential for the safe and effective use of a corresponding drug or biological product. The test helps a health care professional determine whether a particular therapeutic product’s benefits to patients will outweigh any potential serious side effects or risks. Companion diagnostics can identify patients who are most likely to benefit from a particular therapeutic product, identify patients likely to be at increased risk for serious side effects due to treatment with a particular therapeutic product, or monitor response to treatment with a particular therapeutic product for the purpose of adjusting treatment to achieve improved safety or effectiveness.36

DNA is the molecule that carries genetic information for the development and functioning of an organism. DNA is self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. The DNA from any two people is 99.9% identical. The differing 0.1% contains variations that influence individuals’ uniqueness.37

Genes are the basic unit of heredity passed from parent to child. Genes are made up of sequences of DNA and are arranged, one after another, at specific locations on chromosomes in the nucleus of cells. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.38

Gene Mutations
A gene mutation is a change in one or more genes. Some mutations can lead to genetic disorders or illnesses.39

Genetic Testing for Inherited Risk
Genetic testing looks for specific inherited changes (variants) in a person’s genes. Genetic variants can have harmful, beneficial, neutral (no effect), or unknown or uncertain effects on the risk of developing diseases. Harmful variants in some genes are known to be associated with an increased risk of developing cancer. These inherited variants are thought to contribute to about 5-10% of all cancers.51

The genome is the complete set of DNA (genetic material) in an organism. In people, almost every cell in the body contains a complete copy of the genome. The genome contains all the information needed for a person to develop and grow.52

Genome Sequencing
Genome sequencing is figuring out the order of DNA nucleotides, or bases, in a genome—the order of As, Cs, Gs, and Ts that make up an organism’s DNA. The human genome is made up of over 3 billion of these genetic letters.53

Immunotherapy is treatment that uses a person’s own immune system to fight cancer. Immunotherapy can boost or change how the immune system works so it can find and attack cancer cells.40

Lab Developed Test (LDT)
A laboratory developed test (LDT) is a type of diagnostic test that is designed, manufactured, and used within a single laboratory. LDTs can be used to measure or detect a wide variety of analytes (substances such as proteins, chemical compounds like glucose or cholesterol, or DNA), in a sample taken from a human body. Some LDTs are relatively simple tests that measure single analytes, such as a test that measures the level of sodium. Other LDTs are complex and may measure or detect one or more analytes. For example, some tests can detect many DNA variations from a single blood sample, which can be used to help diagnose a genetic disease.41

Liquid Biopsy
Liquid biopsy is a test done on a sample of blood to look for cancer cells from a tumor that are circulating in the blood or for pieces of DNA from tumor cells that are in the blood. A liquid biopsy may be used to help find cancer at an early stage.42

Molecular Profiling
Molecular profiling is a laboratory method that uses a sample of tissue, blood, or other body fluid to look for certain genes, proteins, or other molecules that may be a sign of a disease or condition, such as cancer.43

Molecular Subtype
The molecular subtype of a cancer is based on the genes the cancer cells express, which control how the cells behave.44

Next Generation Sequencing
Next-generation sequencing (NGS) is a massive parallel sequencing technology that offers ultra-high throughput, scalability, and speed. There are multiple different NGS platforms that use different sequencing technologies. All NGS platforms perform sequencing of millions of small fragments of DNA in parallel. Bioinformatics analyses are used to piece together these fragments by mapping the individual reads to the human reference genome. Each of the three billion bases in the human genome is sequenced multiple times, providing high depth to deliver accurate data and insight into unexpected DNA variation.45

Panel Test
A panel test is a laboratory procedure in which a series of tests is performed on one specimen.46

A pathologist is a medical healthcare provider who examines bodies and body tissues. They are also responsible for performing lab tests. A pathologist helps other healthcare providers determine diagnoses and is an important member of the treatment team.47

Precision Medicine
Precision medicine looks at the genetics, environment, and lifestyle of a person to select treatment that could work best for them.48

Prior Authorization
Prior authorization (PA) refers to a requirement by health plans for patients to obtain approval of a health care service or medication before the care is provided. It is supposed to contain costs, ensure that a treatment is medically necessary, and protect patient safety. PA requirements can delay treatment, restrict access to medications or specialists, and increase costs for patients and clinical practices.49

Single Analyte Test
A single analyte test is an assay designed for testing or measuring only a single analyte, which is a chemical substance in a fluid or other specimen from the body.50

Targeted Therapy
A targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific types of cancer cells with less harm to normal cells. Some targeted therapies block the action of certain enzymes, proteins, or other molecules involved in the growth and spread of cancer cells.54
