Chemotherapy doesn't work as well against melanoma as it does for some other types of cancer. Doctors are more likely to use newer drugs called targeted cancer drugs or immunotherapy first to treat melanoma.
Early-stage melanomas can often be treated with surgery alone, but more advanced cancers often require other treatments.
Chemotherapy: This is a combination of powerful drugs used to kill cancer cells. It's recommended more often with stage III. Chemo is usually only an option for stage IV if other treatments haven't worked.
Surgery is the main treatment for melanoma. Radiotherapy, medicines and chemotherapy are also sometimes used. The specialist care team looking after you will: explain the treatments, benefits and side effects.
The typical treatment approach for stage III melanoma is a wide excision surgery to remove the primary tumor, as well as a dissection to remove the lymph node(s). Following surgery, further treatment may include chemotherapy, immunotherapy, targeted therapies, or radiation therapy.
How fast does melanoma spread and grow to local lymph nodes and other organs? “Melanoma can grow extremely quickly and can become life-threatening in as little as six weeks,” noted Dr. Duncanson.
According to the American Cancer Society, the five-year survival rate for people diagnosed with stage 3 melanoma that has spread to nearby lymph nodes or structures (regional spread) is 66 percent. For patients diagnosed with stage 4 melanoma (distant spread), the five-year survival rate is 27 percent.
What are the signs of late-stage skin cancer? Melanoma is considered stage 4 when it has metastasized to lymph nodes in a part of the body far from the original tumor or if it has metastasized to internal organs like the lungs, liver, brain, bone or gastrointestinal tract.
Normally, the first place a melanoma tumor metastasizes to is the lymph nodes, by literally draining melanoma cells into the lymphatic fluid, which carries the melanoma cells through the lymphatic channels to the nearest lymph node basin.
Targeting gene changes can stop the cancer from growing and spreading. Medications that can do this include dabrafenib (Tafinlar), trametinib (Mekinist), and vemurafenib (Zelboraf).
Treatments for Stage I Melanoma
If cancer cells are found in the lymph nodes, further treatment will become necessary, such as a lymph node dissection (removing nearby lymph nodes), chemotherapy, immunotherapy, or targeted therapies.
Melanomas that are less invasive tend to have a better prognosis than deep melanomas, even if there is the involvement of the lymph nodes.
In previous studies, the response rate to chemotherapy in advanced melanoma was very low, ranging from 5% to 28% with a median of 15%.
almost all people (almost 100%) will survive their melanoma for 1 year or more after they are diagnosed. around 90 out of every 100 people (around 90%) will survive their melanoma for 5 years or more after diagnosis.
Knowing your risk can help you be extra vigilant in watching changes in your skin and seeking skin examinations since melanomas have a 99% cure rate if caught in the earliest stages. Early detection is important because treatment success is directly related to the depth of the cancerous growth.
If your melanoma has spread to other areas, you may have: Hardened lumps under your skin. Swollen or painful lymph nodes. Trouble breathing, or a cough that doesn't go away.
feeling sick. poor appetite and weight loss. a swollen tummy (called ascites) yellowing of the skin and whites of the eyes (jaundice)
How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.
The 5-year survival rate is around 15% to 20%. The 10-year survival rate is 10% to 15%. This rate is higher if the cancer has spread only to the skin or distant lymph nodes and not to vital organs.
Although many physicians treat melanoma surgically three to four weeks after diagnosis, there is no official recommendation on time to treatment.
Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. Higher levels of an enzyme called lactate dehydrogenase (LDH) may be a sign of more advanced melanoma.
Stage IV melanoma is difficult to cure as it has already spread to other parts of the body. However, a growing number of people respond well to treatment, achieve No Evidence of Disease (NED), and survive for many years.
If a sentinel node biopsy yields findings of melanoma in the lymph nodes, the 5-year survival is approximately 75%. Stage IIA: The 5-year relative survival rate is approximately 85%. If a sentinel node biopsy yields findings of melanoma in the lymph nodes, the 5-year survival is approximately 65%.
According to the American Cancer Society , the 5-year survival rate for stage 4 melanoma is 15–20 percent. This means that an estimated 15–20 percent of people with stage 4 melanoma will be alive 5 years after diagnosis. Many different factors influence an individual's chance of survival.
