Patients diagnosed with ovarian endometrioid carcinoma without local lymph node metastases (pN0, n = 7) had a significantly higher TAAR1 expression (median IRS of 4) than patients with local lymph node metastases (pN1, n = 3) (median IRS of 3) (Figure 4b). This evidence concerns the gene TAAR1 and ovarian endometrioid carcinoma.
