Abstract:
183 Background: Alkaline phosphatase (ALP) is an enzyme that is elevated by various hepatobiliary diseases. Generally its elevation is thought to indicate bile stasis. There are some reports that show ALP is an important prognostic factor for several cancers such as colon, lung, and gastric cancer. Often it is speculated that ALP elevation indicates bile stasis caused by liver metastasis. However, the significance of ALP elevation in advanced pancreatic cancer (APC) patients is not well evaluated. The aim of this study was to determine the significance of elevated serum ALP as a prognostic factor in patients with APC even without jaundice and liver metastasis. Methods: Serum ALP levels were measured in 393 patients with APC receiving gemcitabine monotherapy before treatment, and according to those levels, patients were subgrouped (ALP 〈 upper normal limit (UNL), UNL-500 U/L, 501-700 U/L, 701-1000 U/L, 1000U/L 〈 ALP). The clinical data of each group were analyzed to see characteristics of elevated ALP patients. The relationship between ALP level and survival, response were also examined. Results: The elevated ALP group included poor performance status (PS 〉 1) patients (41.3%, p=0.001), and associated with low serum albumin (3.31±0.38, p 〈 0.01). The elevated ALP group (median survival time (MST) 112 days) showed significantly worse prognosis and lower disease control rate compared to the normal ALP group (MST 217days) (p 〈 0.001, p 〈 0.001). Multivariate analysis revealed ALP (p 〈 0.001), CRP (p 〈 0.001), ascites (p 〈 0.001), distant metastasis (p=0.003), white blood cell count (p=0.005), PS (p=0.020), AST (p=0.020), and ALT (p=0.020) were independent prognostic factors. Similar results were seen in liver metastasis free patients without jaundice. Conclusions: Elevated serum ALP level correlated with poor performance status and low serum albumin. ALP was also the independent prognostic factor in liver metastasis free APC patients without jaundice. No significant financial relationships to disclose.
