GNG7 and pancreatic adenocarcinoma: The Multivariate Cox Regression analysis showed that the GNG7 (HR (95%CI): 2.106 (1.357–3.269); P = 0.010) and ADCY1 (HR (95%CI): 1.881 (1.221–2.898); P = 0.004) low expression, neoplasm histology grades 3/4 (HR (95%CI): 0.637 (0.408–0.995); P = 0.047), preoperative pharmaceutical history (HR (95%CI): 0.452 (0.281–0.725); P = 0.001) were independent risk factors for overall survival of PAAD (Table 3).
