Why is high growth fraction significant in cancer treatment?

It indicates the body’s immune response
It correlates with chemotherapy effectiveness
It predicts survival rates
It determines radiation sensitivity

The correct answer is: It correlates with chemotherapy effectiveness

High growth fraction is significant in cancer treatment because it correlates with the effectiveness of chemotherapy. The growth fraction refers to the proportion of tumor cells that are actively dividing at any given time. Tumors that have a high growth fraction are generally more sensitive to chemotherapy agents, which are designed to target rapidly dividing cells. This relationship is crucial because chemotherapy is most effective during cell division, making high growth fraction tumors more likely to respond positively to this treatment modality. In contrast, tumors with a low growth fraction may be less responsive to chemotherapy because a significant number of cells are in a resting state and not actively dividing. This concept underpins treatment decisions and can influence the overall management of the cancer, including the choice of therapies and the expected outcomes for the patient.
