Clinical Significance of the PRAME Gene Expression in Oncohematological Diseases

Although the PRAME activity was first discovered in solid tumors, this gene is very frequently expressed in oncohematological diseases. PRAME can be regarded as a reliable biomarker of tumor cells. Determination of PRAME transcripts is used in residual disease monitoring and molecular relapse diagnostics. Experimentation with PRAME expressing lines of leukemia cells yielded controversial results. Therefore, it is hardly possible to estimate the prognostic value of PRAME activity in oncohematological diseases. In chronic myeloproliferative disease and chronic myeloid leukemia, however, PRAME activity proves to be a predictor of negative prognosis, and on the contrary, it can be regarded as a positive prognostic factor in acute myeloid or lymphoid leukemia. Despite many clinical studies prognostic value of PRAME expression in some diseases requires further investigation. The present literature review contains the data concerning PRAME expression in oncohematological diseases.
