Bone Marrow Acid Phosphatase: Another Look

Abstract

Recent reports indicated that bone marrow acid phosphatase is the most sensitive test in detecting bony metastases in prostate cancer. The experience reported suggests that falsely positive results may be common, especially in patients with primary hematologic disorders. Caution should be given to the interpretation of this test so that some patients will not be denied appropriate therapy and the role of bone marrow acid phosphatase can be better defined by long-term followup in such patients.
