Is personalized medicine the future of health care? Many health professionals — including Texas Tech University Health Sciences Center Associate Professor of Molecular Pathology, Katie Bennett — believe the field is headed in that direction.
Personalized medicine, as the name suggests, is an approach that tailors the healthcare process — from diagnosis to treatment — to the individual patient. By identifying a person’s susceptibility to certain diseases and other unique physiological characteristics, this customized approach can identify effective preventive measures and therapies. Also known as precision medicine or individualized medicine, this model can, in turn, lead to improved diagnoses, earlier interventions, tailored treatment plans, and more effective pharmaceutical products, according to the Mayo Clinic.
An important component of personalized medicine is molecular pathology, an emerging multidisciplinary area of medicine that studies disease at the molecular level. As demand for personalized medicine grows, so will the importance of molecular pathology in the diagnosis and treatment of many of the country’s most significant diseases.
What Is Molecular Pathology?
When it comes to defining what is molecular pathology, it helps to break down the phrase into its components: “molecular” refers to molecules and “pathology” means disease. Put simply, molecular pathology is the study of disease at the molecular level. This includes molecules found in tissues, organs, and even bodily fluids. The term “molecular diagnostics” is often used to describe the medical diagnosis aspect of the field.
“In molecular pathology, we are specifically interested in analyzing DNA and other genetic material for the purpose of diagnosing or monitoring disease,” Bennett says. “The field is extremely dynamic — we are learning new things about genetics and medicine every day. The technology is also being developed at mind-blowing rates, which means we are doing testing faster, cheaper, and with smaller instruments than even just a few years ago.”
What Does Molecular Pathology Test For?
Through molecular and genetic approaches, molecular pathology techniques are used across a variety of specialties to diagnose and assess risk for a multitude of diseases. According to the Mayo Clinic, some of the applications in this arena include risk assessment for familial cancer, prenatal and preimplantation diagnosis, and the identification of certain neurologic disorders. This type of testing can also be utilized to assess malignancies for staging or diagnostic uses.
According to Bennett, there are three major categories of diseases that can benefit from molecular pathology.
“Molecular pathology testing is very diverse,” Bennett says. “Because we analyze DNA, one of the first categories that comes to mind for most people is testing for inherited disease.”
Some common examples of inherited diseases that molecular diagnostics tests for, says Bennett, include cystic fibrosis and sickle cell anemia.
“We can also look for the DNA of infectious organisms, such as bacteria and viruses,” Bennett says. “So molecular testing is a big part of medical microbiology, by testing for things like influenza, listeria, or E. coli.”
The third major category, according to Bennett, is cancer. Tumors can be tested for their molecular profiles, which differ from healthy cells in significant ways. Oftentimes, molecular scientists can use mutations and other genetic alterations they discover to identify appropriate and effective therapies for the patient’s unique case of cancer — the foundation of personalized medicine.
What is molecular pathology doing to fight cancer? Personalized medicine, utilizing strategies that include molecular pathology techniques, can use specific information related to the patient’s tumor to help diagnose, plan treatment, assess the effectiveness of a treatment, or develop a prognosis, according to the National Cancer Institute. Targeted therapies can even be used to treat specific classes of cancer cells, or identify tumor markers that can help diagnose cancer.
Utilizing Molecular Pathology Tools in Health Care
Wondering what is molecular pathology using to obtain these results? As the practice of molecular pathology evolves, so does the technology that enables this important testing. In providing care for patients, molecular scientists use many advanced technologies and instruments that represent the cutting-edge of modern health care.
According to Bennett, examples of these tools include PCR thermocyclers, Sanger sequencers, pyrosequencers, and digital PCR. Because the work calls for the routine use of very small volumes of liquid, hand-held pipettors or automated liquid handling instruments are also commonly found in molecular pathology labs.
“When I show someone around the lab, I call these tools ‘my toys’ because using the technology is so much fun,” Bennett says. “It is exciting to have cutting-edge technology at our fingertips here at the Texas Tech University Health Sciences Center. I enjoy showing students how to use these instruments because it really opens their eyes to all of the amazing things we can do in molecular pathology.”
The Texas Tech University Health Sciences Center (TTUHSC) training lab facility is equipped with state-of-the-art equipment, which provides students with hands-on training in some of the most complex gene-testing instruments available to professionals today. The laboratory space is divided into a preanalytical room — used for DNA and RNA isolation — and a postanalytical room, which is used for PCR, DNA sequencing and viral assays. According to Bennett, the techniques that students learn are the same as those that are currently used by clinical labs, forensic labs, research facilities, and industrial organizations across the nation.
Using the latest technology, like the equipment in the Texas Tech University Health Sciences Center training lab, molecular pathology professionals are able to provide patients, and the scientific community in general, with the most valuable results — saving lives and furthering the evolution of the field.
Exploring Health Professions in Molecular Pathology
Because of the many different applications of molecular technology, there is great variety in the jobs that are available in the field. In addition to being diverse in nature, these roles can be found in a number of professional settings, including hospitals, independent laboratories, and the biotechnology industry.
Of these health professions, one of the most common job titles is “molecular technologist” — which is sometimes also referred to as “molecular laboratory scientist.” In this role, typically found in hospitals and independent laboratories, you are responsible for activities related to the tests performed in molecular labs. This can include tasks such as evaluating new methods, carrying out tests, and overseeing lab management.
Particularly interested in the technology side of molecular pathology? You can help others learn about these tools as a field application specialist, providing pre- and post-sale support in real-time. Or you could help move the field forward with new technology and techniques as a research and development scientist.
Bennett reports that there are also a number of careers in the biotechnology industry, where a molecular pathology graduate can land an industrial role as a scientist working to improve many of the tools and processes of the field, such as diagnostic test design, validation, installation, and service.
“We also have graduates who are successful in biomedical sales and public health, and even some working in forensic science as DNA analysts,” Bennett says. “Molecular pathology is never stagnant, which keeps things interesting for those of us who work in the field.”
