Cervical cancer is the most common gynecological malignancy worldwide, and the leading cause of cancer related deaths among females. Conventional treatment for early cervical cancer is radical hysterectomy. In locally advanced cancer the treatment of choice is concurrent chemo radiation. Although such treatment methods show promise, they do have adverse side effects. To minimize these effects, as well as prevent cancer re-occurrence, new treatment methods are being investigated. Photodynamic therapy (PDT) involves the selective uptake of a photosensitizer (PS) by cancer cells, illumination with light of an appropriate wavelength that triggers a photochemical reaction leading to the generation of reactive oxygen and subsequent tumor regression...

OBJECTIVE: Kaplan-Meier survival analysis may overestimate cumulative incidence in competing risks (CR) settings. The clinical significance of this overestimation has been questioned and CR methods are infrequently used. This meta-analysis compares the Kaplan-Meier method to the cumulative incidence function (CIF), a CR method. STUDY DESIGN AND SETTING: We searched MEDLINE, EMBASE, BIOSIS Previews, Web of Science (1992-2016), and article bibliographies for studies estimating cumulative incidence using the Kaplan-Meier method and CIF...

OBJECTIVE: This study aims to evaluate the efficacy and safety of parecoxib injection in pain relief after laparoscopic surgeries. METHODS: Comprehensive literature search based on four online databases (Pubmed, EMBASE, CENTRAL, ISI Web of Science) was applied to retrieve all related randomized controlled trials (RCTs). Two independent reviewers screened each article for eligibility according to the predetermined inclusion criteria. The Cochrane's Tool was applied to evaluate the methodological quality of included studies...

BACKGROUND AND OBJECTIVES: Total pelvic exenteration are performed in patients with locally advanced or recurrent pelvic malignances. Many patients have prolong hospital length of stay (LOS), but risk factors are not clearly identified. METHODS: From 2002 through 2012, 100 consecutive patients undergoing pelvic exenteration were retrospectively reviewed. A general linear model was used to examine risk factors for prolonged hospital LOS. RESULTS: Among the 100 patients, 51 had gastrointestinal cancer, 14 had genitourinary cancer, 31 had gynecologic cancer, and 4 had sarcoma...

Fanconi anemia (FA) is a rare genetic disorder associated with predisposition to head and neck and gynecological squamous cell cancers. In the general population, these cancers are commonly linked to human papillomavirus (HPV) infection. Antibodies to natural HPV infection and HPV vaccination were evaluated in 63 individuals with FA while considering host immune factors. Approximately 30% of reportedly unvaccinated participants were seropositive (HPV6-38%, HPV11-25%, HPV16-26%, and HPV18-26%). Seropositivity was significantly associated with having had sex regardless of age (p=...

OBJECTIVE: The objective of this study was to evaluate the cosmetic outcome of robotic single-site hysterectomy (RSSH) in early-stage endometrial cancer. METHODS: We prospectively collected patient demographics, operative times, complications, pathologic results, and length of stay on all patients who underwent RSSH for early-stage endometrial cancer. The Patient and Observer Scar Assessment Scale (POSAS) was used for the evaluation of the cosmetic outcome. RESULTS: Forty-five patients were included in our study from January 2012 to October 2015...

OBJECTIVE: Ovarian cancer is a common gynecological cancer, and parity is negatively associated with the incidence of this disease. This negative association is hypothesized to be due in part to shifting the balance of estrogen and progesterone toward more progesterone and reduced ovulation during pregnancy. However, studies suggested that parity is also associated with estrogen-independent gynecological cancers suggesting balance of hormones may not be the only protective factor. Extracellular vesicles (EVs) play an important role in cell-to-cell communication in physiological and pathological conditions...

Formyl peptide receptor 2 (FPR2) has been identified as a member of the G protein-coupled chemoattractant receptor (GPCR) family and has been implicated as playing a role in both inflammation and cancer development. Epithelial ovarian cancer (EOC) has been suggested to be correlated with both infectious and non-infectious inflammation. To date, the role of FPR2 in EOC remains poorly understood and controversial. In the present study, we aimed to investigate the potential of FPR2 in regulating EOC. We performed immunohistochemistry and RT-qPCR to analyzed expression of FPR2 in EOC tissues and the correlation between FPR2 and EOC clinicopathological characteristics as well as prognosis were also analyzed...

Ovarian cancer (OC) is the fifth leading cause of cancer‑associated mortality among women in developed countries. Numerous microRNAs are aberrantly expressed in epithelial (E) OC, and are involved in EOC formation and progression. As such, microRNAs may be investigated as diagnostic and prognostic molecular biomarkers, and therapeutic targets for patients with EOC. For instance, microRNA‑455 (miR‑455) is abnormally expressed in various types of human cancer. However, details on the expression level, biological roles and underlying mechanism of miR‑455 in EOC remain unclear...

OBJECTIVE: Obstetrician-gynecologists are the main providers of women's healthcare. However, workforce shortages and excessive workloads among these providers have been encountered in many countries. While most past studies on this subject have investigated the spatial distribution of obstetrics-gynecology clinics, few have focused on their temporal availability, especially on the national level. MATERIALS AND METHODS: The weekly opening time schedules (divided into morning, afternoon, and evening sessions) of all obstetrics-gynecology clinics in Taiwan were extracted from the web site of Taiwan's National Health Insurance Administration in July 2015...

Microcephaly is a rare birth defect, however, the re-emerging mosquito and sexual transmitted flavivirus, Zika virus (ZIKV), had changed the situation and caused an urgent challenge for the obstetrics and gynecology. This review will brief summarize the epidemiology and virology of ZIKV. And compared the animal models that had developed for the ZIKV infections. These animal models will be benefit for the development of vaccines and anti-ZIKV drugs. Furthermore, the genes that are involved in the causation of microcephaly were also summarized...

OBJECTIVE: Tolerance of and complications due to minimally invasive hysterectomy and staging in the older endometrial cancer population is largely unknown despite the fact that this is the most rapidly growing age group in the United States. The objective of this retrospective review is to compare operative morbidity by age in patients on the Gynecologic Oncology Group (GOG) LAP2 trial. METHODS: This is a retrospective analysis of patients from GOG LAP2, a trial that included clinically early stage uterine cancer patients randomized to laparotomy vs...

Polycystic ovary syndrome (PCOS)is a gynecological endocrine disorder which is associated with systemic inflammatory status inducing red blood cells (RBC) membrane alterations related to insulin resistance and testosterone levels which could be greatly improved by myo-inositol (MYO) uptake. In this study we aim to evaluate the effect of MYO in reducing oxidative-related alterations through in vitro study on PCOS RBC. Blood samples from two groups of volunteers, control group (CG, n = 12) and PCOS patient group (PG, n = 12), were analyzed for band 3 tyrosine phosphorylation (Tyr-P), high molecular weight aggregate (HMWA), IgG in RBC membranes, and glutathione (GSH) in cytosol, following O/N incubation in the presence or absence of MYO...

BACKGROUND: Early detection and differentiation diagnosis of a pelvic mass (PM) is crucial in improving the prognosis of patients with epithelial ovarian cancer (EOC). C-C motif chemokine ligand 18 (CCL18) was reported as a chemokine-mediated tumor-related inflammation that can be detected in serum and may correlate with cancer patients' prognosis. OBJECTIVE: We performed this study to investigate the relationship between CCL18 levels and clinical characteristics of EOC patients, and to explore their diagnostic and prognostic values...
