N2 - Anecdotal reports and series studies indicate that 5-10% of pancreatic cancer (PC) cases are familial. In addition, PC is associated with a variety of hereditary cancer syndromes. PC appears to be an integral cancer in the hereditary breast-ovarian cancer (HBOC) syndrome, with most notice given to the role of BRCA2. Our purpose is to call attention to BRCA1, which also predisposes to PC. Using data from our familial breast cancer registry, we identified 19 BRCA1/2 families that contain PC affecteds in the pedigrees, 15 with BRCA1 mutations and 4 with BRCA2 mutations. The association between BRCA2 and pancreatic cancer is well established; however, a definite link with pancreatic cancer in families carrying a BRCA1 mutation has been far less studied. Thus, the focus of this report is on 9 of the 15 BRCA1 families, in which PC affecteds were either confirmed carriers of the BRCA1 mutation or were inferred as probable obligate BRCA1 mutation carriers. The numbers are small, but nevertheless illustrate the finding of others of an apparent association between PC and BRCA1-mutation-bearing families. Given the dismal prognosis of PC, with the only current hope for survival being through surgical extirpation of the pancreas prior to metastasis, it is prudent that we realize the potential predisposition toward PC via BRCA1, in the hope of early diagnosis and prevention.
