AIMS AND BACKGROUND: Variations in serum alkaline phosphatase (ALP) and placental-like (heat stable) alkaline phosphatase (PLAP) are found to be clinically useful in cancer patients. The present study evaluated serum ALP and PLAP levels to establish a blood-based biochemical index for leukemia patients.
STUDY DESIGN: ALP and PLAP levels were determined in 145 untreated leukemia patients, 77 anemia patients, 150 healthy individuals (controls), 47 leukemic patients in remission and 23 patients with persistent leukemic activity/accelerated leukemic phase (P. Leu./A. Leu.). The enzymes were estimated with highly specific spectrophotometric methods.
RESULTS: Serum ALP and PLAP levels were significantly elevated in anemia patients and leukemia patients compared to controls. Comparison between anemia patients and leukemia patients showed insignificant differences for ALP, whereas PLAP levels were significantly raised (p < 0.001) in leukemia patients. ALP showed insignificant difference between untreated leukemia patients, patients with P. Leu./A. Leu. and leukemia patients in remission. PLAP levels were comparable in patients with P. Leu./A. Leu. and were significantly lower (p < 0.02) in leukemia patients in remission than in untreated leukemia patients.
CONCLUSIONS: The results indicate that serum PLAP levels are a useful biochemical marker for diagnosis and treatment monitoring of leukemia patients. However, serum ALP levels have limited utility for leukemia patients.
