Which manifestations are common during the accelerated phase and blast crisis of leukemia?

• A. Bone pain, fevers, weight loss
• B. Severe hyponatremia and edema
• C. Isolated coughing
• D. Seizures only

Answer: (A)

During the accelerated phase and blast crisis, leukemia blasts proliferate rapidly in the bone marrow, expanding the marrow space and crowding out normal hematopoiesis. This marrow expansion often causes bone pain. The systemic symptoms come from the high metabolic activity of the malignant cells and from infection risk due to neutropenia and cytokine effects, leading to fevers and weight loss. So bone pain, fevers, and weight loss reflect the aggressive progression and systemic impact of the disease. Other options don’t fit as well because severe hyponatremia with edema isn’t a defining feature of these leukemia phases, isolated coughing isn’t a typical sign of disease advancement, and seizures alone don’t capture the common symptom pattern seen with accelerated progression.
