OBJECTIVES: To evaluate the postoperative pathological characteristics of hysterectomy specimens, preoperative cancer antigen (CA)-125 levels and imaging modalities in patients with endometrial cancer and to build a risk matrix model to identify and recruit patients for retroperitoneal lymphadenectomy. METHODS: A total of 405 patients undergoing surgical treatment for endometrial cancer were retrospectively reviewed and analyzed. Clinical (age and body mass index), laboratory (CA-125), radiological (lymph node evaluation), and pathological (tumour size, grade, lymphovascular space invasion, lymph node metastasis, and myometrial invasion) parameters were used to test the ability to predict lymph node metastasis...

Inhibitor of DNA-binding protein 3 (Id3) is required for tumor angiogenesis and regulatory T-cell generation. However, the involvement of Id3 in unexplained repeated implantation failure (RIF) and recurrent miscarriage (RM) remains poorly understood. Immunohistochemistry was used to identify Id3, CD34, CTLA-4, and FOXP3 in the endometrium taken from the women with RIF (n=16), RM (n=16) and matched controls (n=8). The images were acquired and analyzed by the Vectra(®) automated quantitative pathology imaging system...

BACKGROUND: Presence of a high neutrophil-to-lymphocyte ratio (NLR) has been associated with increased mortality in several malignancies. Here, we quantify the effect of NLR on survival in patients with gynecologic cancers, and examine the effect of clinico-pathologic factors on its prognostic value. METHODS: A systematic search of electronic databases was conducted to identify publications exploring the association of pre-treatment blood NLR with overall survival (OS) and event-free survival (EFS) among patients with ovarian, endometrial and cervical cancers...

Lymphoepithelioma-like carcinoma (LELC) of the uterine cervix is exceedingly uncommon. We herein report a rare case of cervical LELC. A 45-year-old woman was admitted to gynecology department with vaginal bleeding for one month. Liquid-based cytology revealed atypical endometrial cells, not otherwise specified on her cervix. On a hysteroscopy, an endocervical mass was identified and the pathologic result was consistent with poorly differentiated squamous cell carcinoma. Magnetic resonance imaging and positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro-D-glucose integrated with computed tomography revealed a 3...

Uterine Tumour Resembling Ovarian Sex-Cord Tumours (UTROSCTs) are an extremely rare type of uterine body tumours arising from the endometrial stroma. Epidemiology, aetiology, pathogenesis, management and natural history of UTROSCTs are still a question of debate, as there is little available data in the literature. Although rare, the possibility of UTROSCTs should be kept in mind, when a patient presents with abnormal bleeding and an enlarged uterus. UTROSCTs appear dirty white/cream-coloured, gelatinous, well-circumscribed mass with smooth surface on macroscopic examination...

BACKGROUND: Pregnancy luteoma is a distinctive non-neoplastic hormone dependent lesion arising in pregnancy and mimicking an ovarian tumour. Fewer than 200 cases have been described in the English-language literature. Its clinical and morphological features are characteristic and must be considered in order to prevent diagnostic misinterpretation. To the best of our knowledge the association of pregnancy luteoma with endometriosis has not been reported in literature to date. CASE REPORT: A 30-year-old pregnant woman with no particular past medical history, consulted her gynaecologist at 17 weeks gestation for routine check-up...

Endometriosis involving the uterine cervix is a rare condition that can lead to diagnostic errors in the interpretation of Pap smear. We report the case of a 41-year-old patient in whom the initial Pap smear revealed three-dimensional clusters of glandular cells with elongated nuclei, occasional mitosis, and atypia, which was interpreted as atypical glandular cells, not otherwise specified (NOS). The patient was taken to colposcopy and endocervical biopsy. Colposcopy was normal and the biopsy presented glands with elongated nuclei and surrounded by endometrial stroma admixed with normal endocervical glands...

microRNA-944 (miR-944) has been reported to be deregulation and play either tumor suppressive or oncogenic function in human malignancies. Previous studies have reported that miR-944 is overexpressed in gynecological malignancies including cervical cancer and breast cancer. While, the clinical significance of miR-944 and its function in human endometrial carcinoma (EC) keep unknown. The levels of miR-944 were analyzed in 68 EC tissues and 20 normal endometrial tissues. Results showed that miR-944 was significantly overexpressed in EC tissues compared to normal endometrial tissues...

: 95 Background: Operative reports (OP) for cancer surgery are usually narrated, although they provide inconsistent and incomplete information for patient care. National standards for cancer OP were unavailable until 2007. Over 10 years, surgeons in four Canadian provinces have transitioned from narrative to electronic synoptic reporting (ESP) for specific cancers. The electronic OP are now considered a patient medical record and integral to subsequent patient care. Surgeons are using electronic reports for quality assurance, billing, medical-legal conflict resolution and research...

BACKGROUND: Ectopic pregnancies occur when the implantation of a fertilized ovum occurs outside the endometrial cavity. Such pregnancies occur in approximately 1.5% to 2.0% of all pregnancies and cause 6% of maternal deaths. OBJECTIVES: To evaluate osteopathic structural examination (OSE) findings in patients with ectopic pregnancies of uncommon locations and to establish the utility of these findings in the diagnosis of these ectopic pregnancies. METHODS: In this prospective case series, a focused OSE was performed on each patient with an ectopic pregnancy at her initial presentation after the patient history but before other diagnostic or laboratory tests were performed and surgical treatment was initiated...
