rotein IHC score of secondary cytoreductive surgery. The IHC scores for each protein were calculated and represented as a bar graph. The IHC score was determined by multiplying the score for staining intensity with the score for positive area. The intensity was scored as follows: 0, negative; 1, weak; 2, moderate; 3, strong. The frequency of positive cells was defined as follows: 0, less than 5%; 1, 5 to 25%; 2, 26 to 50%; 3, 51 to 75%; 4, more than 75%
