## Medical Sur... ### VII-Gene Therapy: Gene therapy includes approaches that correct genetic defects or manipulate genes to induce tumor cell destruction in the hope of preventing or combating disease. This type of therapy involves the insertion of a desired gene into the targeted cells. Although gene therapy is currently investigational, researchers predict it will have a profound impact on medical and health care in the future. An example of one such trial involves inserting tumor suppressor gene into cancer cells. Normally this gene is responsible for repairing damaged cells or causing cell death when the cell cannot be repaired. ### Other Medical Interventions. #### A-Blood Component Therapy - The goal of blood component therapy is to administer on the component needed by the patient. This minimizes transfusion reactions and increases the number of patients who can benefit from a single unit. - Granulocytes are used to treat patients with granulocytopenia with severe infection, particularly those in whom severe bone marrow depression develops during chemotherapy. Granulocytes are collected from a single donor by means of a machine that withdraws donor blood, removes the granulocytes, and returns the rest of the blood to the donor. This procedure, called leukapheresis. - Platelets are usually given to patients with thrombocytopenia and bone marrow depression resulting from chemotherapy or radiation therapy. - The nurse is an essential member of the team involved in this therapy; it is often the nurse who identifies the patient's need for blood components, recruits donors, obtains the blood components from the donors, and administers the therapy to the patient. #### B-Hyperthermia: Hyperthermia (thermal therapy), the generation of temperatures than physiologic fever range (above 41.5°C [106.7°F], has been used for
