BACKGROUND: PancPRO is a computer program that estimates the risk of pancreatic cancer for asymptomatic individuals based on a genetic model of susceptibility and the familial incidence of cancer. AIM: To evaluate the distribution of the familial risk in a series of incident cases of pancreatic adenocarcinoma. MATERIALS AND METHODS: The lifetime risk of pancreatic cancer was calculated by PancPro for a hypothetical 40-year-old son of 570 consecutive probands with pancreatic cancer. RESULTS: The 570 risk values were included between 1\% and 13\%. The distribution was bimodal, with the antimode located at risk=7.5\%. Considering a 10-fold risk over the general population as a threshold for including a subject in a surveillance program, 19 families (3.3\%) would be selected, totalling 92 first-degree relatives with age >40 years. CONCLUSIONS: PancPro is a valid instrument to rank families based on risk of pancreatic cancer.
