PURPOSE: Our purpose was to comparatively investigate the expressions of nidogen-1 (NID1) and legumain (LGMN) in patients with endometrial cancer, endometrial intraepithelial neoplasia, and proliferative endometrium.
METHODS: A cross-sectional, single-center study was performed by the obstetrics and gynecology and pathology departments of our institution. The relationships between descriptive data, clinicopathologic information, and immunohistochemical expressions of NID1 and LGMN were investigated.
RESULTS: The histological grades of endometrial cancers (n = 124) as classified by FIGO included 1 (41, 21.1%), 2 (48, 24.7%), and 3 (35, 18.0%). The medians and ranges of deep and superficial NID1 expressions were 50.00 (0-285) and 5.00 (0-100), respectively. The intensity of legumain expression was noted as negative (30, 24.2%), mild (16, 12.9%), moderate (27, 21.8%), or strong (51, 41.1%). Median disease-free survival and overall survival were 75.00 (range: 1 to 170) months and 77.00 (range: 1 to 170) months, respectively. Patients with more intense expression of NID1 and LGMN displayed a higher histological grade. These patients were more likely to have a positive peritoneal cytology, larger tumor size, higher tendency for myometrial or lymphovascular invasion, involvement of ovaries, cervix, omentum, as well as lymph node metastasis, and recurrence.
CONCLUSION: Our data indicated that the expressions of NID1 and LGMN may have important diagnostic implications in endometrial pathologies. Further studies should be performed to understand the significance of NID1 and LGMN in the pathogenesis of endometrial tumors.
