What is a key difference between induction and consolidation chemotherapy phases?

Induction chemotherapy is primarily designed to achieve remission by rapidly reducing the tumor burden and eliminating as many cancer cells as possible. This initial phase creates a state where the disease is controlled or eradicated to the fullest extent achievable. The success of induction therapy is measured by its ability to bring about clinical remission, which is often characterized by a significant decrease in tumor size or the absence of detectable disease.

Consolidation chemotherapy, on the other hand, takes place once remission has been achieved during the induction phase. Its main goal is to eliminate any residual cancer cells that may remain in the body, thus reducing the risk of relapse. This phase is crucial for long-term disease management because it aims to solidify the gains made during induction and improve the likelihood of sustained remission.

Understanding this distinction highlights the complementary nature of the two phases in a comprehensive treatment plan for cancer. Induction sets the stage for remission, while consolidation reinforces that achievement and seeks to eradicate any remaining disease.
