When is targeted therapy used?
Targeted therapy is a cancer treatment that uses drugs to target specific genes and proteins that are involved in the growth and survival of cancer cells. Targeted therapy can affect the tissue environment that helps a cancer grow and survive or it can target cells related to cancer growth, like blood vessel cells.
What is the most effective treatment for cancer?
Chemotherapy is one of the most commonly used treatments for advanced cancer. It may also be used for symptom relief. A combination of chemotherapy drugs may be used, or chemotherapy may be combined with other treatments as part of a broader treatment plan.Mar 4, 2021
How does cancer treatment work?
Chemotherapy is the use of drugs to destroy cancer cells. It usually works by keeping the cancer cells from growing, dividing, and making more cells. Because cancer cells usually grow and divide faster than normal cells, chemotherapy has more of an effect on cancer cells.
What is your role and responsibility in the health and safety Program as an employee?
It is the duty of every employee at work to take reasonable care for the health and safety for himself as well as other persons. Every worker is in other words responsible to take care of his or her own health and safety. The unsafe acts of the worker may not negatively impact or endanger others.
What is the role of Occupational Safety and Health Administration OSHA regulations?
OSHA's mission is to ensure that employees work in a safe and healthful environment by setting and enforcing standards, and by providing training, outreach, education and assistance. Employers must comply with all applicable OSHA standards.
What are two responsibilities employees have when it comes to the Occupational Safety and Health Act?

Why is pharmacogenomics important?
Pharmacogenomics is important in cancer treatment and chemotherapy drug metabolism.
What is pharmacogenomics cancer?
Pharmacogenomics-based cancer treatments are designed to interact with specific molecules that are part of the pathways and processes used by cancer cells to grow, divide, and spread throughout the body. One example of this more personalized approach to cancer treatment is imatinib mesylate ...
What are inhibitors and inducers?
Inhibitors and inducers can be other medications, herbal supplements, foods, and/or environmental exposures such as smoking. Inhibitors cause inactivation of the specific CYP enzymes. An individual’s metabolism returns to normal functioning when the inhibitor has been removed and new enzymes have been made.
What are the four ways that individuals metabolize drugs called?
Genetic changes in Cytochrome P450 result in four different ways individuals metabolize drugs, called phenotypes: <ul. Ultrarapid metabolizers have an increased efficiency in drug metabolism resulting in a possible decrease in effectiveness at established doses.
What are the roles of cytochrome P450?
Many of the cytochrome P450 enzymes play a central role in the metabolism of drugs that are used clinically to treat cancer. Genetic changes in these enzymes include insertions and deletions of genes, single nucleotide polymorphisms, called SNPs, and gene copy number variations. Genetic changes in Cytochrome P450 result in four different ways ...
Why is it so difficult to counsel patients about pharmacogenomic based cancer treatments?
Counseling patients about pharmacogenomic-based cancer treatments and testing and how they metabolize drugs is challenging because of limited long-term safety and efficacy data. Another challenge is that availability of testing may be limited to those who have particular insurance or financial resources and those patients enrolled in clinical trials.
How does genetic change affect cancer?
The accumulation of genetic changes alters cell signaling pathways and other cellular functions. Traditional cancer chemotherapy uses drugs that destroy not only malignant cells but healthy cells too.
What are some examples of pharmacogenomic testing in cancer care?
Here are some examples of pharmacogenomic testing in cancer care: Colorectal cancer. Irinotecan (Camptosar) is a type of chemotherapy. Doctors commonly use it to treat colon cancer. In some people, genetic variations cause a shortage of the UGT1A1 enzyme. This enzyme is responsible for metabolizing irinotecan.
What are the factors that influence a person's reaction to a drug?
This means that they may have more side effects from the drug. Besides pharmacogenomics, other factors may influence a person’s reaction to a drug: Age and gender. The cancer’s stage. Lifestyle habits, such as smoking and drinking alcohol.
What enzyme is responsible for metabolizing chemotherapy?
About 10% of people have genetic variations in an enzyme called thiopurine methyltransferase (TPMT). TPMT is responsible for metabolizing chemotherapy for ALL. Children with lower TPMT levels receive lower chemotherapy doses.
Why do doctors use test results?
Test results help the doctor choose the safest and most effective drug and dose. Pharmacogenomics is constantly changing. Researchers continue to identify gene variations that affect how a drug works. As personalized medicine grows, testing for gene variations may become more common.
How do variations affect how fast a drug changes into its active form?
The variations affect how fast a drug changes into its active form. For example, some bodies break down drugs slowly. This means standard doses of treatment may not work as well. Drug deactivation. Drugs also need to be "turned off" to limit the drug’s exposure to healthy tissues.
Why do drugs work differently?
Why drugs work differently in different people. Drug activation. Many drugs that treat cancer need to be "turned on" to work. This process is called activation. Proteins called enzymes speed up chemical reactions in the body. This activates a drug so that it can do its job. Each person inherits variations in enzymes.
What is standard genetic testing?
Standard genetic testing is a type of testing that searches for specific genes. For example, a test may look for BRCA1 and BRCA2 genes, which are linked with a higher risk of breast and ovarian cancer. The results from standard genetic test may prompt preventive or risk reduction steps. These include:
What is the radical transformation in cancer treatment?
This type of radical transformation in cancer treatment is what’s possible with precision medicine and pharmacogenomics, says Arash Bashirullah, associate professor in the Pharmaceutical Sciences Division of the University of Wisconsin–Madison School of Pharmacy.
What is precision medicine?
Precision medicine is essentially personalized therapeutic intervention, which can be tailored to the individual as well as their unique disease. The new position within the School of Medicine and Public Health, likely to be housed in the Department of Oncology or McArdle Laboratory for Cancer Research, will be focused on the manifestation of cancer itself—tumors.
Why do drug companies use pharmacogenomics?
Drug companies are also using pharmacogenomics to develop and market medicines for people with specific genetic profiles.By studying a drug only in people likely to benefit from it, drug companies might be able to speed up the drug’s development and maximize its therapeutic benefit.
How do genes affect medicine?
What role do genes play in how medicines work? Just as our genes determine our hair and eye color, they partly affect how our bodies respond to medicine. Genes are instructions, written in DNA, for building protein molecules. Different people can have different versions of the same gene.
What is the long term goal of genetics?
Its long-term goal is to help doctors select the drugs and doses best suited for each person. It is part of the field of precision medicine, which aims to treat each patient individually. Your genes determine a lot about how you look. They also play a key role in how medications work in your body. Credit: NIH.
Can doctors prescribe drugs to people who don't have genes?
In addition, if scientists can identify genes that cause serious side effects, doctors could prescribe those drugs only to people who do not have those genes. This would allow some individuals to receive potentially lifesaving medicines that otherwise might be banned because they pose a risk for other people.
Why do drug companies use pharmacogenomics?
Drug companies are also using pharmacogenomics to develop and market medicines Using Genes to Guide for people with specific genetic profiles. By studying a drug only in people likely to Prescriptions Article from benefit from it, drug companies might be able to speed up the drug’s development Inside Life Science and maximize its therapeutic benefit.
