Survival time is expressed as median ± SD. 1p-value for comparison of the 3 types; 2p-value for comparison of the OPN+ and OPN- groups. * p = 0.041 and p = 0.010 for comparison with the intestinal type and other type OPN+ AC, respectively. There was no difference between intestinal AC and other type of AC (p = 0.907).
