Which statement best describes nonspecific immunotherapy?

• A. It can be used as the primary treatment or as an adjunct to other cancer treatments using cytokines.
• B. It uses vaccines to stimulate a targeted immune response.
• C. It relies solely on surgical intervention.
• D. It has no effect on the immune system.

Answer: (A)

Nonspecific immunotherapy boosts the immune system in a broad, non-targeted way, often using cytokines to enhance overall immune activity rather than attack a specific tumor antigen. Because cytokines can stimulate immune cells broadly, they may be used as the primary treatment or added to other cancer therapies to support the body’s defenses. In contrast, vaccines aim to provoke a targeted immune response to a specific antigen, and surgery is not an immunotherapy. So using cytokines as either a main therapy or an adjunct fits the description of nonspecific immunotherapy.
