As can be seen in Table 1, while the state of receptors co-expression showed minimal variation in relation to tumor size, receptors co-expression decreased in relation to lymph node involvement from 38.23% to 28.12% for PRLR/TGFβRI and from 36.11% to 21.21% for PRLR/TGFβRII. Here, PRLR is linked to neoplasm.
