ABO blood group is associated with pancreatic cancer (PC) risk. Whether ABO blood group alone or when combined with inherited mutation status of index PC cases (probands) can enhance PC risk estimation in first-degree relatives (FDRs) is unclear. We examined FDRs’ risk for PC based on probands’ blood group and probands’ cancer susceptibility gene mutation status. Data on 23,739 FDRs, identified through 3,268 PC probands, were analyzed. Probands’ ABO blood groups were determined serologically or genetically, and 20 susceptibility genes were used to classify probands as “mutation-positive” or “mutation-negative.” SIRs and 95% CIs were calculated, comparing observed PC cases in the FDRs to the number expected in SEER-21 (reference population). Overall, FDRs had two-fold risk of PC (SIR=2.00, 95%CI=1.79-2.22). PC risk was higher in FDRs of mutation-positive (SIR=3.80, 95%CI=2.81-5.02) than mutation-negative (SIR=1.79, 95%CI=1.57-2.04) probands (p<0.001). Risk magnitudes did not differ by ABO blood group alone (SIRblood-group-O=1.57, 95%CI=1.20-2.03, SIRnon-O=1.83, 95%CI=1.53-2.17;p=0.33). Among FDRs of probands with non-O blood group, PC risk was higher in FDRs of mutation-positive (SIR=3.98, 95%CI=2.62-5.80) than mutation-negative (SIR=1.66, 95%CI=1.35-2.03) probands (p<.001), but risk magnitudes were statistically similar when probands had blood group O (SIRmutation-positive=2.65, 95%CI=1.09-5.47, SIRmutation-negative=1.48, 95%CI=1.06-5.47;p=0.16). There is a range of PC risk to FDRs according to probands’ germline mutation status and ABO blood group, ranging from 1.48 for FDRs of probands with blood group O and mutation-negative to 3.98 for FDRs of probands with non-O blood group and mutation-positive.
