BACKGROUND: Parity and breastfeeding are associated with systemic changes in maternal inflammation and reduced risk of ovarian cancer, but little is known about their impact on the ovarian tumor immune microenvironment. METHODS: We evaluat…

To evaluate whether deeper histologic sections and tissue-blocking practices improve the diagnosis of endometriosis in peritoneal biopsies. We retrospectively reviewed 148 peritoneal biopsy cases with clinical suspicion of endometriosis fro…

Endometriosis is a benign, estrogen-dependent condition, usually occurring in menstruating and, rarely, in postmenopausal women, in which endometrial glands and stroma grow ectopically outside the uterus. Most often, ectopic endometrial tis…

BACKGROUND: Cigarette smoke exposure has been linked to systemic immune dysfunction, including for B-cell and immunoglobulin (Ig) production, and poor outcomes in patients with ovarian cancer. No study has evaluated the impact of smoke expo…

Endometriosis, a painful gynecological condition accompanied by inflammation in women of reproductive age, is associated with an increased risk of ovarian cancer. We evaluated the role of peritoneal heme accumulated during menstrual cycling…

OBJECTIVES: To describe the sonographic findings of endometrial intraepithelial neoplasia (EIN), a precursor of endometrial cancer. METHODS: Cases were found by word search of pathology database 1/2013 to 6/2019. One hundred and seventy-ei…

BACKGROUND: Differential associations between ovarian cancer risk factors and estrogen receptor-α (ERα) ovarian tumor expression have been noted; however, no research has assessed estrogen receptor-β (ERβ) expression. Thus, in exploratory a…

Endometrial cancer is the most common gynecologic neoplasm in developed countries; however, updated universal guidelines are currently not available to handle specimens obtained during the surgical treatment of patients affected by this dis…

Although endometrial carcinoma (EC) is generally considered to have a good prognosis, over 20% of women with EC die of their disease, with a projected increase in both incidence and mortality over the next few decades. The aim of accurate p…

Background: One model of ovarian cancer development model divides tumors into two types. Type I tumors are characterized by KRAS and BRAF mutations, which can activate mitogen-activated protein kinase (MAPK). Type II tumors are characterize…

OBJECTIVE: We assessed the association between reproductive and hormonal factors and ovarian cancer incidence characterized by estrogen receptor-α (ERα) and progesterone receptor (PR) status. METHODS: Tissue microarrays were used to assess…

Differentiating ovarian tumors based on developmental pathway may further enhance our understanding of the disease. Traditionally, ovarian cancers were thought to arise from the ovarian surface epithelium; however, recent evidence suggests …

Abstract Context .—Endometrial carcinoma of endometrioid histology is frequently preceded by endometrial hyperplasia, from which localized, premalignant lesions called endometrial intraepithelial neoplasia (EIN) emerge. Diagnostic criteria …

The Society of Radiologists in Ultrasound convened a panel of specialists from gynecology, radiology, and pathology to arrive at a consensus regarding the management of ovarian and other adnexal cysts imaged sonographically in asymptomatic …

Hormone receptor expression in tumors may offer etiologic information for ovarian cancer, particularly in light of known associations with hormonal and reproductive risk factors. Tissue microarrays constructed from 157 paraffin-embedded blo…
