Final answer:
B-ALL has an excellent response to chemotherapy, making it a largely curable disease.
Step-by-step explanation:
The statement that B-ALL has an excellent response to chemotherapy is true.
Acute lymphoblastic leukemia (ALL) is a type of cancer that affects the white blood cells called lymphocytes. Combination chemotherapy, which involves the use of multiple drugs, has been highly effective in treating B-cell ALL.
For example, the POMP regimen, which consists of methotrexate, vincristine, 6-mercaptopurine, and prednisone, has been successful in inducing long-term remissions in children with ALL. Clinical studies have shown that ALL in children has become a largely curable disease with the use of chemotherapy.
