title: Androstanediol glucuronide in patients with pancreatic cancer and in those with chronic pancreatitis.
abstract: The differential diagnosis between pancreatic cancer and chronic pancreatitis is extremely difficult. Beside CA19-9 level determinations, many tests have been tried with the aim to facilitate this distinction. Serum androgen levels have been used for this purpose. To further explore the value of androgen markers in differentiating pancreatic cancer from chronic pancreatitis we determined the serum levels of androstanediol glucuronide and of androgens in the two groups of patients and compared them with CA19-9 levels. A total of 25 males were entered into the study. Of these, 13 patients had pancreatic cancer and 12 chronic pancreatitis. They were comparable as to their body weight and age. Patients with pancreatic cancer had significantly lower serum testosterone, dihydrotestosterone and androstanediol glucuronide levels, but not testosterone/dihydrotestosterone ratios when compared to patients with chronic pancreatitis. Only androstanediol glucuronide and dihydrotestosterone serum concentrations had such a small overlap between the two groups that could be used for differentiation, their sensitivity and specificity being comparable to those of CA19-9 levels. The present study has shown for the first time that serum androstanediol glucuronide levels in male patients with pancreatic cancer are significantly lower than in those patients with chronic pancreatitis. Furthermore, the sensitivity and specificity of serum andorstanediol glucuronide levels which can be used to differentiate between pancreatic cancer and chronic pancreatitis are comparable to those of CA19-9.
