CD4 and diffuse large B-cell lymphoma: In the United States, a report on 41 patients diagnosed with DLBCL concluded that the blood CD4 level was a lesser factor in predicting the occurrence of DLBCL.23 The median CD4 count of their study was 400 cells/μL. It has been reported that a haemoglobin value of less than 10 g/dL and white cell count less than 4 × 109 significantly increases the likelihood of bone marrow involvement in non-Hodgkin’s lymphoma.24 About 99% of cases reported for DLBCL in our study had no bone marrow infiltration.
