An oncology nurse is contributing to the care of a patient who has failed to respond appreciably to conventional cancer treatments. As a result, the care team is considering the possible use of biologic response modifiers (BRFs)
The nurse should know that these achieve a therapeutic effect by what means?
A) Promoting the synthesis and release of leukocytes
B) Focusing the patient's immune system exclusively on the tumor
C) Potentiating the effects of chemotherapeutic agents and radiation therapy
D) Altering the immunologic relationship between the tumor and the patient
Ans: D
Feedback:
BRFs alter the immunologic relationship between the tumor and the cancer patient (host) to provide a therapeutic benefit. They do not necessarily increase white cell production or focus the immune system solely on the tumor. BRFs do not potentiate radiotherapy and chemotherapy.
