Introduction
The “leukemia gap phenomenon” is a morphological term referring to a marked proliferation of nucleated cells—predominantly blasts—in the bone marrow of leukemia patients, accompanied by a conspicuous absence of intermediate-stage maturing cells and only a few residual mature granulocytes, thereby creating a so-called “gap” or “empty space” appearance. Since leukemia is a malignant clonal disorder of hematopoietic stem cells, hematopoiesis becomes dysregulated—characterized by uncontrolled proliferation and impaired differentiation of the hematopoietic system.

Leukemia is a relatively common clinical condition among children and adolescents. It is often associated with a phenomenon known as the “leukemic gap” (or “leukemia gap phenomenon”). But what exactly is the leukemic gap phenomenon?

Leukemic Gap Phenomenon

The leukemic gap phenomenon is a morphological term describing a characteristic finding in the bone marrow of leukemia patients: marked hyperplasia of nucleated cells dominated by blast cells, with an absence of intermediate-stage maturing cells, while only a few mature granulocytes remain—creating what is termed a “gap” or “void” appearance.

Leukemia is a malignant clonal disorder originating from hematopoietic stem cells. In this condition, proliferation within the hematopoietic system becomes uncontrolled, and cellular differentiation is impaired—resulting in the accumulation of large numbers of blasts and immature cells in the bone marrow. This disrupts normal physiological functions. Thus, the so-called “leukemic gap” arises due to dysfunction of hematopoietic stem cells in leukemia patients.

Leukemia results from pathological changes in blood cells. Such patients exhibit significantly higher protein consumption than healthy individuals. Only high-quality protein can sustain the proper function of various tissues and organs. Additionally, protein serves as a building block for antibodies, which protect the body against bacterial and viral infections and enhance overall immunity. Vitamin A stimulates the immune system, promotes anti-cancer activity, and helps resist pathogen invasion. Foods rich in vitamin A include carrots, pumpkin, alfalfa sprouts, bell peppers, and pineapple. We hope this explanation proves helpful.
