Spatially Resolved Epithelial–Immune Heterogeneity Identifies an Endometriosis Subtype with Molecular Features of Endometriosis-Associated Ovarian Cancer
·doi:10.21203/rs.3.rs-10497180/v1

Abstract Evidence suggests that clear cell and endometrioid ovarian carcinoma may arise from endometriosis. We previously identified that some endometriosis lesions exhibit a “cancer-like” PD-1/PD-L1 positive staining similar to endometr…

Abstract PR018: Spatially resolved epithelial and immune heterogeneity reveals distinct endometriosis-related precursors to ovarian cancer
·doi:10.1158/1538-7445.ovarian25-pr018

Abstract Evidence suggests that certain histotypes of ovarian carcinoma -mainly clear cell (CCOC) and endometrioid (EOC) carcinoma-may arise from endometriosis (EAOC), although the biological mechanisms underlying this phenomenon remain unc…

Ovarian endometrioid carcinoma with a sex cord-like pattern: a morphological, immunohistochemical, and molecular analysis.
Virchows Archiv : an international journal of pathology ·doi:10.1007/s00428-024-03743-6

Sex cord-like endometrioid carcinoma (SCLEC) is an uncommon entity which may constitute a diagnostic challenge. This study aimed to perform a clinicopathological, immunohistochemical, and molecular reappraisal of ovarian SCLEC. Consecutive …

Abstract 3647: Digital spatial transcriptomic reveals different epithelial and immune cells signatures across endometriosis-related diseases: From simple ovarian endometriosis to ovarian cancer
·doi:10.1158/1538-7445.am2024-3647

Abstract Endometriosis represents a pressing medical concern, imposing a relevant burden on patients including potential malignant transformation into endometriosis-associated ovarian cancer (EAOC). Despite the process of cancer development…

Frozen section accurately allows pathological characterization of endometrial cancer in patients with a preoperative ambiguous or inconclusive diagnoses: our experience.
BMC cancer ·doi:10.1186/s12885-019-6318-5

BackgroundThe aim of this study was to assess the agreement rate between intraoperative evaluation (IOE) and final diagnosis (FD) in a series of surgically resected endometrial carcinoma (EC), with a preoperative ambiguous or inconclusive d…
