On the basis of the number and severity of the phenotypic abnormalities detected, a scoring system is proposed that efficiently discriminates between normal/reactive and MDS CD34 + HPC, the mean. The abnormal cells grow, but they do not fight infections or perform other functions like normal WBCs. The results may also be used to predict how aggressive the cancer will be and/or whether it will respond to certain treatment. Application of these criteria to a series of nearly 500 cases of lymphoma indicated that over 90% of B-lineage and about 80% of T-lineage neoplasms manifested immunophenotypic abnormalities that could distinguish them from benign, reactive lymphoid processes. al.
