ANS: D
Combination therapy is far superior to the use of single agent therapy. The use of a cell cycle-specific and cell cycle-nonspecific agents together facilitates cell death during different phases of the cell cycle. Combination therapy is not more economical or faster. Combination therapy is not less toxic because it exposes patients and nurses to additional medications. The use of combination drug therapy allows for cell death during different phases of the cell cycle, but the agents often have toxic effects on different organs at different time intervals after administration.
