What is cytotoxic?
Cytotoxic refers to a substance or process which results in cell damage or cell death. The prefix "cyto" refers to cell and "toxic" to poison. The term is often used to describe chemotherapy drugs that kill cancer cells, but it may also be used to describe toxins, such as venom. Within our own immune systems, we have cells that are considered cytotoxic, such as the T cells that kill bacteria, viruses, and cancer cells. 1 The label "cytotoxic" is important for medical professionals who will be handling cytotoxic medications or other substances that can cause cell death, and specific precautions are necessary for safety. Cytotoxicity testing is important in ensuring safety ranging from environmental exposures to medical devices. 2
What is the term for the ability of a substance to cause damage to cells?
The term cytotoxic refers to the ability of a substance to cause damage to cells. The term genotoxic refers to the ability of a substance to directly damage DNA in cells. When DNA is damaged, it may or may not die. In fact, the persistence of cells harboring damaged DNA (mutations) that are not repaired underlies the development of cancer.
How do cytotoxic agents kill cells?
Cytotoxic agents can kill cells in several ways. They may harm the cell so that its cell membrane is weakened and the cell explodes (lysis) or they may interfere with cell division so the cell stops growing and dividing. 5
Why do chemotherapy cycles repeat?
The reason that most chemotherapy regimens include a combination of drugs ( combination chemotherapy ), and that most chemotherapy cycles are repeated, is because cells are in various places in the division process. Not all drugs used to treat cancer are cytotoxic. Chemotherapy drugs are designed to kill all rapidly growing cells, ...
What is the T cell?
Cytotoxic T cells (CD8+ cells and natural killer lymphocytes) are part of the immune system, which searches for, finds and destroys cells infected by viruses as well as cancer cells.
What are the genes that cause cancer?
Cancer often arises following a series of mutations in both oncogenes (genes that code for proteins that drive the growth of cells) and tumor suppressor genes (genes that code for proteins that repair damaged DNA or cause a cell to die if the DNA cannot be repaired). BRCA genes are examples of tumor suppressor genes.
Why are cytotoxic agents used in chemotherapy?
Cytotoxic agents are used in chemotherapy because they can be effective at stopping or slowing the division and spread of cancer cells. They are powerful drugs that can lead to side effects ranging from nausea to anemia to potentially life threatening complications of major organs.
What is cytotoxic agent?
Cytotoxic agents are substances that destroy cells. “Cytotoxic” means toxic or deadly to cells. In the treatment of cancer, cytotoxic agents are used to prevent cancer cells from dividing and spreading.
What is the most commonly used cytotoxic agent?
Anthracyclines are the most widely used type of cytotoxic agent. These drugs bind with DNA, preventing it from making copies of itself and therefore interfering with its reproduction. They are used in the treatment of bladder cancer, breast cancer, and many other types of cancer.

What is immunotherapy for cancer?
Cancer immunotherapy is a treatment that empowers a patient’s own immune system to fight cancer. Immunotherapy works to harness and enhance the natural powers of the immune system to work against the disease—by enabling it to recognize, target, and eliminate cancer cells throughout the body.
How effective is each treatment?
Clinical studies have shown that beneficial responses to cancer immunotherapy treatment can be durable and can be maintained even after treatment is completed. Additionally, some evidence has revealed that certain types and doses of chemotherapy can enhance immune responses against tumors, thus providing another rationale for combining these treatments in certain settings.
How does immunotherapy work?
Unlike chemotherapy, which acts directly on cancerous tumors, immunotherapy treats patients by acting on their immune system. Immunotherapy can boost the immune response in the body as well as teach the immune system how to identify and destroy cancer cells.

Although you should always speak to your health care professionals and seek their guidance about your treatment options, it’s also important for patients themselves to understand their treatments and how that could change their experiences and outcomes. Immunotherapy has the potential to help people affected by cancer —here’s why.
Can immunotherapy cause side effects?
In contrast, immunotherapy’s potential side effects usually result from an overstimulated or misdirected immune response, and can range from mild to moderate or severe and can become potentially life-threatening under certain circumstances.
Alkylating Drugs
Cytotoxic Antibiotics
- Also known as “antitumor antibiotics,” these agents are not like the antibiotics you take to treat a bacterial infection. Instead, they work by changing the DNA within cancer cells to block them from multiplying. Some examples of cytotoxic antibiotics include: 1. anthracyclines such as: 1.1. doxorubicin (Lipodox) 1.2. valrubicin (Valstar) 2. non-an...
Antimetabolite Drugs
- Antimetabolite drugs work by interfering with the DNA and RNA of cancer cells, replacing parts that are necessary for DNA and RNA construction. As a result, the DNA cannot make copies of itself, and the cells can no longer reproduce. Antimetabolite drugs are among the most widely used chemotherapy agents. They’re often used to treat: 1. leukemia 2. breast cancer 3. ovarian c…
Vinca Alkaloids
- Vinca alkaloids are made from the Madagascar periwinkle plant. They are the second most-used class of cancer drugs, often used in combination with other medications, according to a report in the International Journal of Preventive MedicineTrusted Source. These agents work by interfering with the microtubules (the parts of a cell that move chromosomes along when cells divide). Vinc…
Photodynamic Drugs and Photodynamic Therapies
- Photodynamic therapyTrusted Sourceinvolves the ingestion of a photosensitizer drug, which is absorbed by cancer cells within a few days. When exposed to a special light, the photosensitizer produces a form of oxygen capable of destroying cancer cells. This therapy is often used to treat skin cancers, including basal cell skin cancer and squamous cell skin cancer. Photodynamic the…
Platinum-Containing Drugs
- As the name suggests, platinum-based drugs contain platinum compounds that bind to a cancer cell’s DNA. It crosslinks in the DNA strands, preventing the cell from reading its own genetic code. When enough of the code can’t be read, the cell dies. Platinum-containing agents are used to treat ovarian cancer, colon cancer, and other cancer types. Examples of platinum-containing drugs in…
Taxanes
- Like vinca alkaloids, taxanes also block cell division by interfering with the microtubules’ ability to transport chromosomes during mitosis. Taxanes are among the most commonly used chemotherapy drugs in the treatment of breast cancer and non-small cell lung cancer, along with several other types of cancer. Two widely used taxanes include paclitaxel (Abraxane) and docet…
Topoisomerase Inhibitors
- Topoisomerase inhibitors are also known as “plant alkaloids” because they’re derived from a type of plant. They disrupt the action of the enzymes topoisomerases, which plays a key role in the separation of DNA strands of cancer cells, allowing them to be copied. Topoisomerase inhibitors are used in the treatment of: 1. leukemia 2. lung cancer 3. ovarian cancer 4. colon cancer 5. pan…
