High Serum Alkaline Phosphatase Flare after First-Line Androgen Deprivation Therapy Predicts Poor Prognosis in Metastatic Prostate Cancer Patients Treated with Second-Generation Androgen Receptor Targeted Therapy

Figure 1

ALP change at 1 and 3 months after starting ADT in patients with (a) initial ALP levels less than 304 U/L and (b) initial ALP levels more than 304 U/L. (c) The ALP flare ratio was the ALP value 1 month after ADT divided by the ALP value at diagnosis. Groups were divided according to initial ALP levels within the normal range (<304 U/L) or higher. The median peak ALP flare ratios were 1.11 and 1.74 in patients with an initial ALP less than 304 U/L and more than 304 U/L, respectively ().
