What is associated with remission of leukemia?

Remission of leukemia indicates a reduction or disappearance of the signs and symptoms associated with the disease, particularly a significant decrease in the number of leukemic cells in the peripheral blood and bone marrow. The presence of noncirculating blast cells in the bone marrow suggests that the disease has been effectively managed or treated, as these cells would not be present in significant numbers if the leukemia is in remission.

In remission, one would expect to see normal blood cell counts and a decrease in the prevalence of leukemic cells, which aligns with the situation where blast cells are no longer circulating in the bloodstream and are confined to the bone marrow.

In contrast, the other options correlate more closely with active leukemia. For example, pancytopenia with circulating blasts, a Philadelphia chromosome in leukemic cells, and lymphocytosis are all signs associated with active disease rather than remission. Pancytopenia with circulating blasts indicates a severe drop in blood cell counts due to the replacement of normal hematopoiesis by leukemic cells, while the Philadelphia chromosome serves as a specific genetic marker frequently seen in chronic myeloid leukemia, often indicating an ongoing disease process. Lymphocytosis, or an increase in lymphocytes, is generally associated with lymphoid leukem
