Mucinous carcinoma (ER: 69.4%, p < 0.0001; PR: 60.9%, p < 0.0001); mixed invasive carcinoma (NOS) and lobular carcinoma (ER: 73.1%, p = 0.0002; PR: 70.2%, p < 0.0001); and tubular/cribriform carcinoma (ER: 71.2%, p = 0.0049; PR: 66.8%, p = 0.0005) had higher estrogen receptor (ER) positivity and progesterone receptor (PR) positivity when compared with invasive carcinoma (NOS) (ER: 50.1%, PR: 40.9%). This evidence concerns the gene PGR and mucinous adenocarcinoma.
