Chemotherapy (continued from privious page): Often, patients who need many doses of IV chemotherapy receive the drugs through a catheter (a thin flexible tube). One end of the catheter is placed in a large vein in the chest. The other end is outside the body or attached to a small device just under the skin. Anticancer drugs are given through the catheter. This can make chemotherapy more comfortable for the patient. Patients and their families are shown how to care for the catheter and keep it clean. For some types of cancer, physicians are studying the advantages of giving anticancer drugs directly to the affected area.
Chemotherapy is generally given in cycles: A treatment period is followed by a recovery period, then another treatment period, and so on. Usually a patient has chemotherapy as an outpatient--at the hospital, at the doctor's office, or at home. However, depending on which drugs are given and the patient's general health, the patient may need to stay in the hospital for a short time.
The side effects of chemotherapy depend mainly on the drugs and the doses the patient receives. Generally, anticancer drugs affect cells that divide rapidly. These include blood cells, which fight infection, help the blood to clot, or carry oxygen to all parts of the body. When blood cells are affected by anticancer drugs, patients are more likely to get infections, may bruise or bleed easily, and may have less energy. Cells that line the digestive tract also divide rapidly. As a result of chemotherapy, patients may have side effects, such as loss of appetite, nausea and vomiting, hair loss, or mouth sores. For some patients, the physician may prescribe medicine to help with side effects, especially with nausea and vomiting. Usually, these side effects gradually go away during the recovery period or after treatment stops. (continued on next page)
