Because SCLC spreads quickly throughout the body, treatment must include cancer-killing drugs (chemotherapy) taken by mouth or injected into the body. Usually, the chemotherapy drug etoposide is combined with either cisplatin or carboplatin.
Combination chemotherapy and radiation treatment is given to people with extensive SCLC. However, the treatment only helps relieve symptoms. It does not cure the disease.
Radiation therapy uses powerful x-rays or other forms of radiation to kill cancer cells. Radiation therapy can be used with chemotherapy if surgery is not possible. Radiation may be used to:
Treat the cancer, along with chemotherapy if surgery is not possible
Help relieve symptoms caused by the cancer such as breathing problems and swelling.
Help relieve cancer pain when the cancer has spread to the bones
Often, SCLC may have already spread to the brain, even when there are no symptoms or other signs of cancer in the brain. As a result, radiation therapy to the brain may be given to some patients with smaller cancers, or to those who had a good response in the first round of chemotherapy. This method is called prophylactic cranial irradiation (PCI).
Very few patients with SCLC are helped by having surgery because the disease has often spread by the time of diagnosis. Surgery may be done when there is only one tumor that has not spread. If surgery is done, chemotherapy or radiation therapy will still be needed.
Cancer Term:(malignant neoplasm) is a class of diseases in which a group of cells display uncontrolled growth, invasion that intrudes upon and destroys adjacent tissues, and sometimes metastasis, or spreading to other locations in the body via lymph or blood. These three malignant properties of cancers differentiate them from benign tumors, which do not invade or metastasize. Cancer-ar-foundation
