OBJECTIVE: The aim of this study was to compare the outcomes and toxicities of radical hysterectomy (RH) and definitive chemoradiation (CRT) for International Federation of Gynecology and Obstetrics (FIGO) stage IIB cervical cancer. MATERIALS AND METHODS: A retrospective analysis was performed on FIGO stage IIB patients who underwent RH with adjuvant radiotherapy (surgery group) or intended to receive CRT (CRT group). The distributions of disease-free survival (DFS) and overall survival (OS) were calculated using the Kaplan-Meier method...

Background: Pap-smears-based cytology and human papilloma virus testing have their own limitations in detecting cervical precancerous lesions, and still need further standardization. Co-expression of p16ink4a and Ki-67 can be used as additional biomarker. Aims: To study the role of liquid-based cytology and the dual immunostaining for p16/Ki-67 in predicting the presence of significant lesion in cases of mild cytological atypia. Materials and Methods: A prospective, cross-sectional study was performed in the Department of Pathology, in collaboration with Department of Obstetrics and Gynecology over 15 months including 545 patients...

PURPOSE: The aim of this study was to evaluate and correlate the amplification of chromosomal regions 3q26 and 5p15 in different cytological and histological subgroups of patients and to compare the sensitivity and specificity of amplification tests with cytology, colposcopy and HPV status. METHODS: The work was conducted at the Department of Obstetrics and Gynaecology in cooperation with the Institute of Pathological Anatomy, JFM CU in Martin and UNM during years 2013-2016...

There is a controversy about whether endometriosis-associated ovarian cancer (EAOC) might represent a different entity from the corresponding ovarian cancer occurring de novo, in the absence of endometriosis. This study investigated the clinical-pathologic characteristics and outcome of EAOC compared with other ovarian carcinomas that are not associated with endometriosis (non-EAOC) in a large cohort. Seven hundred two patients meeting the inclusion criteria were further subclassified as group I when patients had ovarian carcinoma associated with or arising within endometriosis (EAOC) and group II when patients had non-EAOC...

OBJECTIVES: To develop and validate a prognostic model of integrating whole-tumour apparent diffusion coefficient (ADC) from pretreatment diffusion-weighted (DW) magnetic resonance (MR) imaging with human papillomavirus (HPV) genotyping in predicting the overall survival (OS) and disease-free survival (DFS) for women with stage IB-IV cervical cancer following concurrent chemoradiotherapy (CCRT). METHODS: We retrospectively analysed three prospectively collected cohorts comprising 300 patients with stage IB-IV cervical cancer treated with CCRT in 2007-2014 and filtered 134 female patients who underwent MR imaging at 3...

The Bi-RADS (Breast Imaging Reporting and Data System) classification developed by the ACR (American College of Radiology) is the classification system for radiological images recommended for breast cancer screening. The ACR 4 microcalcification is an indeterminate or suspected abnormality with 2-95% probability of malignancy, according to studies. This disparity pushed us to conduct this retrospective study of 181 patients in the Department of Obstetrics and Gynecology I at the Hassan II University Hospital, Fez, over a period of 5 years...

Objective To determine the frequency and type of histopathologic lesions in placentas delivered by women with a normal pregnancy outcome. Methods This retrospective cohort study included placental samples from 944 women with a singleton gestation who delivered at term without obstetrical complications. Placental lesions were classified into the following four categories as defined by the Society for Pediatric Pathology and by our unit: (1) acute placental inflammation, (2) chronic placental inflammation, (3) maternal vascular malperfusion and (4) fetal vascular malperfusion...

OBJECTIVE: Diagnosis of endometrial clear cell carcinomas is difficult owing to the low reproducibility of histological cell type in high-grade endometrial cancers. Recently, immunoreactivity for napsin A and glypican 3 has been reported in clear cell cancers. We sought to evaluate the use of napsin A and glypican 3 staining to distinguish clear cell carcinoma from other high-grade endometrial cancers. METHODS/MATERIALS: Twenty cases of pure and mixed endometrial clear cell carcinoma were extracted from the 2000-2014 archival material in the Departments of Obstetrics & Gynecology and Pathology at Montefiore Medical Center and compared to serous and grade 3 endometrioid controls...

BACKGROUND: Matrix metalloproteinase-2 (MMP-2), a member of the zinc-dependent metalloproteinase gene family, plays a vital role in cancer invasion, metastasis, and progression. This systematic review and meta-analysis aims to explore the clinical significance of MMP-2 expression in endometrial cancer. METHODS: PubMed, Embase, Cochrane Library, and China National Knowledge Infrastructure databases were systematically searched up to September 30, 2017, supplemented by manual searches of bibliographies...

OBJECTIVE: Choice of hysterectomy and adjuvant treatment for International Federation of Gynecology and Obstetrics (FIGO) 2009 stage II endometrioid endometrial cancer (EEC) is still controversial. Aims of this study were to evaluate survival benefits and adverse effects of different hysterectomies with or without adjuvant radiotherapy (RT), and to identify prognostic factors. METHODS: The patients at 14 member hospitals of the Taiwanese Gynecologic Oncology Group from 1992 to 2013 were retrospectively investigated...

OBJECTIVE: Since there have been few large series studies to date, we investigated the relationship between Trousseau's syndrome associated with cerebral infarction and its clinical associations with ovarian cancer. METHODS: In this study, we investigated the association between cerebral infarction onset and ovarian cancer. Eight-hundred twenty-seven consecutive ovarian cancer patients from 4 affiliated academic institutions were included in the study over a 12 years period...

OBJECTIVE: We aimed to identify the minimum tumor-free margin distance conferring long-term oncological safety in patients diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage IB/II vulvar squamous cell carcinoma (VSCC). METHODS: This was a retrospective cohort study in patients with stage IB/II VSCC treated at a single institution in Turin, Italy.

The epidemiologic characteristics of HPV genotypes vary by age, ethnicity, geographic location and the available data of HPV epidemiological characteristics with cytology results in Sichuan province are limited. Our research was conducted from June 2016 to July 2017. A total of 10953 women getting HPV testing were enrolled. Liquid-based cytological results and histological results were collected. The overall HPV infection rate was 24.1% in Sichuan province. The prevalence of hrHPV were 19.9%. For hrHPV genotypes, HPV52 (15...

Extrauterine leiomyomas are very rare and present a clinical and diagnostic challenge due to their unusual growth patterns and behaviours. A 47-year-old woman was transferred to our tertiary specialist obstetrics and gynaecology hospital with acute abdominal pain and a palpable abdominal mass. She was taken immediately to theatre with the presumptive diagnosis of an ovarian torsion. Intraoperatively, a large necrotic mass originating from the mesentery and attachments to the bowel at the ileocaecal junction was noted...
