Abstract
The nucleated cell count in bone marrow of 18 gastric cancer cases showed decrease in 12 cases and megakaryocyte count was decreased in 6 of 11 cases. Studies on the myelogram in 20 cases revealed increases of neutrophilic promyelocytes, plasma cells, and reticulum cells. Neutrophilic segmented cells and eosinophilic leucocytes were found decreased in number. No significant change was observed in basophilic leucocyte, monocyte, lymphocyte, and erythroblast countings. The differentiation of neutrophilic system revealed disturbance of maturation in 16, aplasia in 2, and normal figure in 2 cases. Study of the erythrocyte system showed 4 cases of aplasia and one case of hyperplasia.
The shortened red cell survival time, nutritional disturbance, disturbance in iron metabolism, bone marrow injury and bleeding were thought to be responsible for the development of the anemia in gastric cancer cases.
