Description

A form of immunotherapy known as cancer vaccines works to treat cancer by boosting the body's inherent anti-cancer defences. Contrary to cancer preventive vaccines, cancer treatment vaccines are intended to be administered to patients who already have cancer; they fight cancer cells, not the disease itself. Tumorassociated antigens, which are thought to be present in cancer cells but absent or at low levels in healthy cells, are the basis for the concept of therapy vaccinations. The immune system can learn to identify and respond to these antigens and eliminate cancer cells that contain them with the aid of treatment vaccinations.

Methods for creating cancer vaccines

They are created from the tumour cells in your body. This indicates that they are specifically designed to elicit an immune response against characteristics that are exclusive to your malignancy.

They might be created using tumor-associated antigens that are present on the cancer cells of several patients with a particular type of cancer. Any patient whose tumour produces that antigen may experience an immunological response after receiving such a vaccination. This kind of vaccine is still in the testing phase.

They could be created from your own immune cells called dendritic cells. Your immune system is stimulated by dendritic cell vaccines to react to an antigen on tumour cells. Sipuleucel-T, a dendritic cell vaccination with FDA approval, is used to treat some men with advanced prostate cancer.

Oncolytic virus therapy, a different kind of cancer therapy, is occasionally referred to as a cancer vaccine. It makes use of an oncolytic virus, a type of virus that attacks and destroys cancer cells while sparing healthy ones. Talimogene Laherparepvec is the first oncolytic viral treatment that the FDA has approved (TVEC, or Imlygic). It is based on type 1 of the herpes simplex virus. Despite the fact that this virus can infect both cancer and normal cells, cancer cells are unable to eliminate the virus.

Who have cancer that has progressed to other parts of the body and who exhibit little to no symptoms or whose cancer is resistant to hormone therapy. Some patients with melanoma that recurs after surgery and cannot be removed with additional surgery are treated with T-VEC.

Adverse effects of cancer vaccinations

Vaccines for cancer treatment may have adverse effects that have varying impacts on different persons. Your pre-treatment health, the type of cancer you have, its stage, the type of therapy vaccination you are receiving, and the amount will all have an impact on the side affects you might have and how they make you feel. The occurrence of side effects, their severity, or when they will occur cannot be predicted with certainty by doctors or nurses. Therefore, it's crucial to be aware of the warning signals and know what to do if you start experiencing issues. Cancer vaccinations can result in flu-like symptoms, such as: fever, chills, weakness, dizziness, weariness, muscle or joint problems, or nausea, headache, difficulty breathing, high or low blood pressure. Tumor lysis syndrome may be brought on by T-VEC. The tumour cells in this disease disintegrate in the blood when they die. This alters some blood molecules, which could harm organs like the heart, liver, and kidneys.
