Treatment and Side Effects of Merkel Cell Carcinoma
Standard Treatments for Merkel Cell Carcinoma
One or more of the following surgical procedures may be used to treat Merkel cell carcinoma:
- Wide Local Excision - The cancer is cut from the skin along with some of the tissue around it. A sentinel lymph node biopsy may be done during the wide local excision procedure. If there is cancer in the lymph nodes, a lymph node dissection also may be done.
- Lymph Node Dissection - A surgical procedure in which the lymph nodes are removed and a sample of tissue is checked under a microscope for signs of cancer. For a regional lymph node dissection, some of the lymph nodes in the tumor area are removed; for a radical lymph node dissection, most or all of the lymph nodes in the tumor area are removed. This procedure is also called lymphadenectomy.
Radiation Therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated.
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.
It helps to learn more about the side effects from your treatment(s) before you begin, so you will know what to expect. When you know more, you can work with your health care team to manage your quality of life during and after treatment. There are effective and readily available medications to address traditional side effects from cancer treatment (such as nausea, diarrhea, constipation and mouth sores.) Also, as newer ‘targeted therapies’ become available, they tend to leave people with fewer traditional side effects. Keep in mind that everyone reacts differently to treatment and experiences side effects differently. There are coping mechanisms and strategies that can help.
Immunotherapy uses the body’s immune system to fight cancer and helps prevent the cancer from returning.
Side Effects for Merkel Cell Carcinoma
Side effects of external radiation therapy may include skin changes, nausea and vomiting, diarrhea, fatigue, painful sores in the mouth and throat and dry mouth or thick saliva. Most side effects of radiation are temporary, but some rare serious side effects can be permanent. In some cases, radiation to the chest can also cause lung damage, which may lead to problems breathing and shortness of breath.
Chemotherapy has different side effects depending on the type and dose of drugs given and the length of time they are taken. These side effects can include hair loss, mouth sores, loss of appetite, nausea and vomiting, diarrhea, increased chance of infections (due to low white blood cell counts), easy bruising or bleeding (due to low blood platelet counts) and fatigue (due to low red blood cell counts.)
