Interleukin-2 (IL-2) is used as adjuvant therapy for a patient with metastatic renal cell carcinoma. The nurse teaches the patient that the purpose of therapy with this agent is to
A. Protect normal kidney cells from the damaging effects of chemotherapy
B. Enhance the patient's immunologic response to tumor cells
C. Stimulate malignant cells in the resting phase to enter mitosis
D. Prevent the bone marrow depression caused by chemotherapy
Correct Answer: B. Enhance the patient’s immunologic response to tumor cells
Option B: IL-2 is a naturally occurring protein that is made by a T-lymphocyte which functions to enhance the growth and activity of other white blood cells. The purpose of this therapy is to enhance the ability of the patient’s own immune response to suppress tumor cells.
Options A, C, and D: IL-2 does not protect normal cells from damage caused by chemotherapy, stimulate malignant cells to enter mitosis, or prevent bone marrow depression.
