Systemic Cancer Therapy
- Chemotherapy. Cytotoxic drugs damage DNA and kill many normal cells as well as cancer cells. Antimetabolites such as fluorouracil and methotrexate are cell cycle–specific and have no linear dose-response relationship.
- Hormone Therapy. Hormone therapy uses agonists or antagonists to influence the course of cancer. It may be used alone or combined with other therapies.
- Immune Therapy. Immune therapy is the newest systemic cancer therapy. Active immune therapy (mediated by active immunity) aims to provoke or amplify an anticancer immune response in a patient with ...
- Adjuvant and Neoadjuvant Therapies. In some cancers with a high likelihood of recurrence after surgery and/or radiation therapy, chemotherapy drugs, hormones, and/or targeted therapy drugs are given to reduce recurrence ...

What is systemic treatment?
(sis-TEH-mik THAYR-uh-pee) Treatment using substances that travel through the bloodstream, reaching and affecting cells all over the body.
Why is chemotherapy a systemic treatment?
Chemo is considered a systemic treatment because the drugs travels throughout the body, and can kill cancer cells that have spread (metastasized) to parts of the body far away from the original (primary) tumor. This makes it different from treatments like surgery and radiation.Nov 22, 2019
How is systemic therapy given?
These are drugs that can be taken by mouth or injected into a vein, muscle, or another part of the body. The way the chemotherapy is given depends on the type and stage of the cancer being treated. The drugs enter the bloodstream and can reach cancer cells throughout the body.
What is the most successful cancer treatment?
Any cancer treatment can be used as a primary treatment, but the most common primary cancer treatment for the most common types of cancer is surgery. If your cancer is particularly sensitive to radiation therapy or chemotherapy, you may receive one of those therapies as your primary treatment.Jun 4, 2020

Which cancer is known as silent killer?
Ovarian cancer has been termed the silent killer because its presenting symptoms are often mistaken for other benign conditions, particularly the ones that affect the gastrointestinal system, or simply changes in a woman's body as she ages.Sep 1, 2017
What is a systemic surgery?
The goal of systemic therapy, which gives medication via the bloodstream, is to treat the whole body. Systemic therapy is most often given in the “adjuvant” setting (in other words, after surgery has been performed) to decrease the risk of the cancer returning.
What are examples of systemic medicines?
Biologics such as infliximab (Remicade), adalimumab (Humira), and etanercept (Enbrel) and oral treatments such as methotrexate and apremilast (Otezla) are all examples of systemic drugs.Feb 1, 2018
What are symptomatic treatments?
Symptomatic treatment: Therapy that eases the symptoms without addressing the basic cause of the disease. For example, symptomatic treatment of advanced lung cancer that has spread (metastasized) beyond the lung is designed to decrease the pain and other symptoms but not to eradicate the disease.

PD-1 and PD-1L antibodies are now widely used to treat solid cancers but not blood and bone marrow cancers. Another example of active immune therapy is instilling bacille Calmette–Guérin (BCG) in the bladder of patients with bladder cancer.
What is monoclonal antibody?
They can also be directed toward lineage-specific antigens also present on normal cells. Some monoclonal antibodies are given directly; others are linked to a radionuclide or toxin. These linked antibodies are referred to as antibody-drug conjugates (ADCs).
What is an active immune system?
Active. Adoptive. Active immune therapy (mediated by active immunity) aims to provoke or amplify an anticancer immune response in a patient with cancer. This can be done, for example, using a cancer cell vaccine alone or combined with an adjuvant, which boosts the desired immune response.
What are some forms of adoptive immune therapy?
Other forms of adoptive immune therapy include lymphokines and cytokines such as interferons and interleukins. These forms are less widely used in cancer therapy.
What are the side effects of gene therapy?
Adverse effects include bone marrow toxicity (eg, infection, bleeding), fatigue, diarrhea, headaches, dizziness, and liver and kidney abnormalities. The most advanced form of gene therapy involves genetically modifying a cancer patient's T cells by inserting a receptor for an antigen onto their cancer cells.
What is systemic treatment?

How much of cancer is metastatic?
Either the body’s immune system or medical intervention prevents them from spreading broadly. Experts estimate 50% of discovered (diagnosed) cancers spread so far they are considered metastatic. Surgery and radiation are impractical for addressing distributed cancer.
