Small-Cell Lung Cancer
Small-Cell Lung Cancer Treatment continued...
Other drugs may be given to prevent and treat adverse effects of radiation, chemotherapy, or the cancer itself, such as nausea or vomiting. Pain medications are also important to relieve any pain due to cancer or its treatment.
Surgery plays little, if any, role in the management of small-cell lung cancer, because almost all cancers have spread by the time they are discovered.
The exceptions are the relatively small number of people (less than 15%) whose cancer is discovered at a very early stage of the disease, when the cancer is confined to the lung without any spread to the lymph nodes. However, surgery alone is not considered curative, so chemotherapy is also given. Sometimes radiation therapy will also be needed if the cancer had spread to the nearby lymph nodes.
Radiation therapy is the use of high-dose X-rays or other high-energy rays to kill cancer cells. Radiation can be given from outside the body using a machine (external radiation therapy), or it can be given with the help of radiation-producing materials that are implanted inside the body (brachytherapy).
Radiation therapy can be curative (kills all cancer cells), prophylactic (reduces the risk of cancer spreading to the area to which it is given), or palliative (helps reduce suffering).
- Patients who are receiving chemotherapy require close monitoring for side effects and response to therapy.
- A blood work-up, including CBC (complete blood count), is needed prior to each cycle of chemotherapy to ensure that the bone marrow has recovered before the next dose of chemotherapy is given.
- Kidney function is monitored, especially if the patient is taking cisplatin, as it can damage the kidneys. Also, carboplatin's dosage is based upon kidney function.
- The patient will undergo a CT scan to assess their response to treatment
- Other tests are performed to monitor liver function and electrolytes -- especially sodium and magnesium levels -- due to the effects of the cancer and its treatment.
Palliative and terminal care
Because small-cell lung cancer is diagnosed in most people when it is not curable, palliative care becomes important. The goal of palliative and terminal care is to manage pain and discomfort and enhance quality of life.
