    Maspin expression in endometrial hyperplasia and endometrial endometrioid adenocarcinomas was assessed and its correlation with p53 and Ki-67 expressions and clinical outcome, as well as its potential to distinguish typical from atypical endometrial hyperplasia, were assessed in this study. Histological sections from 114 cases of endometrial endometrioid adenocarcinoma, 75 cases of endometrial hyperplasia (typical and atypical), and 23 normal endometrial tissue samples were examined. The most representative hematoxylin-eosin slides were selected and 2-3 micron-thick sections were cut for immunohistochemical staining with maspin, p53, and Ki-67 antibodies. While there was no maspin expression in normal endometrial cells, it was present in 14.5% of the patients with endometrial hyperplasia without atypia. Staining for maspin was positive in atypical hyperplasia and endometrial adenocarcinoma in, respectively, 45% and 49.1% of the cases studied. No statistically significant correlations were found between maspin and Ki-67 antibodies or p53 expression. Our findings showed that maspin expression, which generally correlates with a less aggressive behavior, is significantly higher in atypical hyperplasia and in endometrial endometrioid adenocarcinoma. Maspin positivity in endometrial hyperplasia could be used to identify pseudo-atypical hyperplasia and could be considered a potentially useful prognostic parameter in those cases in which adenocarcinomas are well differentiated.

    Systemic immune and tumor marker profiles in ovarian and deep infiltrating endometriosis: associations with disease severity and symptom burden

    Endometriosis is a chronic, estrogen-dependent inflammatory disease with heterogeneous clinical manifestations and uncertain systemic immune involvement. This study aimed to characterize peripheral immune profiles and circulating tumor markers in women with ovarian endometrioma (OE) and deep infiltrating endometriosis (DIE), and to explore their associations with disease severity, symptom burden, and physical health perception. Peripheral blood leukocyte subsets, plasma cytokines, and tumor markers (CA125, CA19-9, CEA, HE4) were analyzed in 146 patients and 50 healthy controls. OE was associated with increased monocyte counts and reduced neutrophil proportions, while DIE showed elevated levels of IL-8 and Galectin-1. IL-33 levels correlated negatively with the revised American Society for Reproductive Medicine (rASRM) scores and positively with neutrophil proportion, suggesting a role in systemic immune regulation. Tumor marker levels varied by subtype: CA19-9 was higher in OE, and CEA in DIE. CA125 correlated with disease severity, and CEA with monocyte levels. Exploratory heatmaps revealed consistent immune-tumor associations linked to anatomical severity and symptom profiles. Although exploratory, these findings highlight the presence of distinct systemic immune patterns in endometriosis and support the potential of integrative blood-based biomarkers for future diagnostic and stratification strategies.
