However, no significant associations were observed between FASN expression and the histological grade (OR, 0.92; 95% CI, 0.41-2.04; P=0.832), TNM stage (OR, 1.11; 95% CI, 0.49-2.53; P = 0.795), lymph node metastasis (OR, 1.42; 95% CI, 0.84-2.38; P = 0.183), Ki-67 labelling index (OR, 0.64; 95% CI, 0.15-2.63; P = 0.533), estrogen receptor (ER) status (OR, 0.90; 95% CI, 0.61-1.32; P = 0.586), or progesterone receptor (PR) status (OR, 0.67; 95% CI, 0.29-1.56; P = 0.354) (Table 3; Figure 3). This evidence concerns the gene PGR and metastatic malignant neoplasm in the lymph nodes.
