Data were presented as mean SD or n of patients (%). There were no significant between-group differences ; continuous data were compared using an independent two-sample t-test or the Mann–Whitney U-test based on data normality; categorical data were compared using Fisher’s exact test. Note: CA199 = carbohydrate antigen 199; CEA = carcinoma embryonic antigen; CA125 = glycogen antigen 125.
