  • Title: Serum prostate-specific antigen in pancreatic disease.
    Author: Pezzilli R, Bertaccini A, Billi P, Zanarini L, Miglio F, Martorana G.
    Journal: Ital J Gastroenterol Hepatol; 1999 Oct; 31(7):580-3. PubMed ID: 10604096.
    Abstract:
    BACKGROUND: Prostate-specific antigen has been considered a specific and sensitive marker of prostate cancer. In recent years, it has been reported that prostate-specific antigen may also be found in pancreatic tissue; however, very little evidence of serum levels of this protein in pancreatic disease has been forthcoming. AIMS: To explore the possibility that pancreatic diseases may influence both total and free serum prostate-specific antigen. PATIENTS AND METHODS: A total of 72 females were studied: 44 patients with acute pancreatitis: 6 with chronic pancreatitis: 12 with pancreatic carcinoma and 10 healthy volunteers. Total and free serum prostate-specific antigen were measured using commercial kits. RESULTS: In patients with acute pancreatitis, total and free serum prostate-specific antigen were detectable in two out of the 44 patients (5%). In patients with chronic pancreatitis, total and free serum prostate-specific antigen were undetectable, whereas 4 out of the 12 patients (33%) with pancreatic carcinoma had detectable serum levels of total and free prostate-specific antigen. CONCLUSIONS: Female patients with acute pancreatitis and especially those with pancreatic cancer may have detectable serum levels of total and free prostate-specific antigen. Further studies are necessary to understand why these molecules are elevated in patients with pancreatic diseases, thus affecting the specificity of prostate-specific antigen determination as a prostate tumour marker.
