SIGNIFICANCE OF CEREBROSPINAL FLUID FERRITINESTIMATION IN CENTRAL NERVOUS SYSTEM LEUKEMIA

Cerebrospinal fluid ferritin (CSF.F) levels arehigher in patients with central nervous system leu-kemia (CNL) or suspected CNL, as compared withnonleukemic patients. Our data shows that changesin CSF.F levels are more marked than any otherCSF routine test parameters in CNL and correlatewell with the disease progress. CSF.F examinationmay help in early diagnosis of CNL. CNL is the origin of leukemic relapSe, so it isvery important to prevent and treat CNL in time.
