Immunotherapy


There are a variety of immunotherapy treatments to help patients with treating advanced melanoma. Immunotherapy is the prevention or treatment of disease with substances that stimulate the immune response. It helps a patient’s own immune system to detect and destroy cancer cells on its own. Newer forms of immunotherapy are available only through clinical trials.

 

Ipilimumab for advanced melanoma

· Man-made version of an immune system protein

· Boosts the immune response against melanoma cells

· Given through an IV once every 3 weeks for 4 treatments

· For patients who can’t have melanoma removed by surgery or it has already spread, it can help these patients live several months longer

· Does not cure melanoma

· Helps against cancer cells, but could lead to problems in in the intestines, liver, hormone-making glands, nerves, skin, eyes, or other organs.

· Immune-related side effects occur during treatment, but can last a few months post-treatment

 

Cytokines for advanced melanoma

· Proteins in the body that boost the immune system

· Can either be given via IV or by injection at home

· Helps shrink advanced melanoma (stage 3 & 4) by 10-20%

· Can be given alongside chemotherapy for stage 4 melanoma

· Side effects: flu-like symptoms (fever, chills, aches, sever tiredness, drowsiness, and low blood cell counts), swelling from fluid build up

· Only given in centers with high experience of this treatment

 

Interferon-alpha as adjuvant therapy

· Is used after surgery for patients with thicker melanomas to try to prevent the cells from spreading and growing

· Delays recurrence of melanoma, but not sure yet if it helps improve survival

· Needs to be had in high doses

· Side effects: fever, chills, aches, depression, severe tiredness, and effects on the heart and liver.

· Patients need to be closely watched by doctors greatly experienced in this treatment

 

Bacille Calmette-Guerin (BCG) vaccine

· Enhances the entire immune system, but is not directed specifically at melanoma cells

· Used to help treat stage 3 melanoma by directly injecting it into tumors

Imiquimod cream

· Stimulates a local immune response against skin cancer cells when applied as a cream

· Can be used for very early stages of melanoma (stage 0) in sensitive areas on the face in place of surgery that could cause disfiguration to the face

· Used for melanomas that have spread along the skin

· Applied anywhere on the body once a day to two times a week for three months

· Patients may have irritation or skin reactions to the cream

· Not used nor recommended for advanced melanomas

  1. Great link. I also clicked on new research and found that there are some genetic trials underway to discover DNA links as a way of treating melanomas, since chemo in late stage is not very effective.

    1. Because my cousin's melanoma was caught at Stage 3, there was nothing really they could do, as most of these treatments only make it so that you live a little bit longer. It's the same for chemo. He chose to do chemotherapy, lost all of this hair and got very skinny, but it did help him live a few months longer.
