Melanoma is a type of skin cancer that occurs when the pigment-producing cells in the skin become malignant. It can spread quickly to other parts of the body, making it one of the deadliest forms of cancer.
However, with recent advancements in immunotherapy and novel drug treatments, there is hope for those battling this disease.
What causes melanoma?
The most common cause of melanoma is exposure to ultraviolet (UV) radiation from the sun or tanning beds. Genetics also play a role, as some individuals are more predisposed to the disease due to inherited mutations in certain genes.
Other risk factors include having a large number of moles, a history of sunburns, and a weakened immune system.
Diagnosis and Treatment
The first step to diagnosing melanoma is typically a skin biopsy. If melanoma is confirmed, further testing is done to determine the stage and extent of the cancer.
Treatment options will depend on the stage of the disease, with early-stage melanoma typically being treated with surgery to remove the affected area. Later-stage melanoma may require additional treatments such as chemotherapy, radiation therapy, or immunotherapy.
Immunotherapy
Immunotherapy is a type of cancer treatment that harnesses the body’s own immune system to fight cancer cells. There are several different types of immunotherapy, including checkpoint inhibitors and CAR T-cell therapy.
Checkpoint inhibitors are drugs that block certain proteins on cancer cells that prevent the immune system from attacking them. By blocking these proteins, checkpoint inhibitors allow the immune system to recognize and attack the cancer cells.
Several types of checkpoint inhibitors have been approved for use in the treatment of melanoma, including ipilimumab and pembrolizumab.
CAR T-cell therapy involves collecting a patient’s T-cells, modifying them to target cancer cells, and then infusing them back into the patient’s body.
This type of therapy has shown promising results in clinical trials for various types of cancer, including melanoma.
Novel Drugs
In addition to immunotherapy, there are also several novel drug treatments being developed for the treatment of melanoma. These drugs target specific genetic mutations that are present in some melanoma tumors.
BRAF inhibitors are drugs that block a mutated protein that is present in about half of all melanoma cases. By blocking this protein, BRAF inhibitors can slow or stop the growth of melanoma tumors.
Vemurafenib and dabrafenib are two examples of BRAF inhibitors that have been approved for use in the treatment of melanoma.
MEK inhibitors are drugs that block a protein that is involved in cell growth and division. By blocking this protein, MEK inhibitors can also slow or stop the growth of melanoma tumors.
Trametinib is an example of a MEK inhibitor that has been approved for use in the treatment of melanoma.
Combination Therapy
Recent research has shown that combining immunotherapy with novel drug treatments can improve outcomes for patients with melanoma.
For example, combining a BRAF inhibitor with a checkpoint inhibitor has been shown to improve progression-free survival in patients with melanoma that has the BRAF mutation.
Prevention
The best way to prevent melanoma is to protect your skin from the sun. This includes wearing protective clothing, using sunscreen with a high SPF, and avoiding tanning beds.
It’s also important to be aware of any changes in your skin, such as new moles or changes in the appearance of existing moles. If you notice any changes, it’s important to see a dermatologist right away.
Conclusion
Melanoma is a serious and potentially deadly form of skin cancer, but there is hope for those battling the disease. Immunotherapy and novel drug treatments are showing promise in improving outcomes for patients with melanoma.
By combining these treatments with prevention efforts such as sun protection and early detection, we can continue to make progress in the battle against this disease.
