Correlation of anemia with infradiaphragmatic involvement in Hodgkin's disease and other malignant lymphomas

A staging laparotomy and splenectomy were performed in 41 patients with Hodgkin's disease and 11 with other malignant lymphomas. There was a significant correlation (P = 0.025) between the presence of unexplained anemia and involvement of the spleen or abdominal lymph nodes by tumour. The anemias were of mild degree; hemolysis was documented in three and iron deficiency in four, while 21 cases were unexplained. Bone marrow was not involved by lymphoma in this series. The complication rate in exploratory laparotomy was higher than previously reported. Severe complications were observed in 17% of these patients while another 15% had minor complications. The association we have discovered may be helpful in the staging of patients who cannot tolerate an operative procedure. The absence of infradiaphragmatic involvement is suggested in the presence of normal hemoglobin concentrations.
