ABSTRACT
This paper aims to elucidate the differentially coexpressed genes, their potential mechanisms, and possible drug targets in low-grade invasive serous ovarian carcinoma (LGSC) in terms of the biologic continuity of normal, borderline, and malignant LGSC. We performed a bioinformatics analysis, integrating datasets generated using the GPL570 platform from different studies from the GEO database to identify changes in this transition, gene expression, drug targets, and their relationships with tumor microenvironmental characteristics. In the transition from ovarian epithelial cells to the serous borderline, the FGFR3 gene in the "Estrogen Response Late" pathway, the ITGB2 gene in the "Cell Adhesion Molecule", the CD74 gene in the "Regulation of Cell Migration", and the IGF1 gene in the "Xenobiotic Metabolism" pathway were upregulated in the transition from borderline to LGSC. The ERBB4 gene in "Proteoglycan in Cancer", the AR gene in "Pathways in Cancer" and "Estrogen Response Early" pathways, were upregulated in the transition from ovarian epithelial cells to LGSC. In addition, SPP1 and ITGB2 genes were correlated with macrophage infiltration in the LGSC group. This research provides a valuable framework for the development of personalized therapeutic approaches in the context of LGSC, with the aim of improving patient outcomes and quality of life. Furthermore, the main goal of the current study is a preliminary study designed to generate in silico inferences, and it is also important to note that subsequent in vitro and in vivo studies will be necessary to confirm the results before considering these results as fully reliable.
ABSTRACT
OBJECTIVE: Our primary aim in this study is to define the clinical characteristics of patients with clear-cell ovarian carcinoma and evaluate the prognostic factors affecting survival. STUDY DESIGN: Records of 85 patients, operated between 2000 and 2018, for an adnexal mass and whose final pathology reported clear cell ovarian carcinoma were reviewed. The study considered demographic data, clinical characteristics of the patients, as well as pure and mixed-type clear cell histology. The patients' follow-up time, disease-free and overall survival recorded. The primary outcomes were disease-free survival (DFS) and overall survival (OS). RESULTS: The median age of the patients at diagnosis was 52. In 64.7 % of the cases, clear cell histology was pure, while the others (35.3 %) were mixed. Patients with ovarian endometriosis constituted 27.1 % of the whole population. The median OS for the entire population was 92 months (95 %CI:72-124). On univariate and multivariate analyses, advanced age was found to have a significant independent impact on OS and DFS (p < 0.05) and, was associated with a worse prognosis. Also, the multivariate analyses showed that the presence of endometriosis has a significant independent impact on OS (p < 0.05). When examining the relationship between the histological origin (mixed vs. pure) and 5-year survival, the mixed type showed longer OS and DFS rates (76.8 % vs. 69.8 %, 61.5 % vs. 53.8 %), the difference was not statistically significant (p > 0.05). CONCLUSION: This retrospective study showed that although mixed type histological origin was associated with higher OS and DFS rates compared to pure type in patients with CCOC, the difference was not statistically significant. Advanced age and the presence of endometriosis was found to have a significant independent effect on OS and DFS and was associated with a worse prognosis. Overall, this study provides useful insights into the clinical characteristics of patients with CCOC and identifies important prognostic factors affecting survival.

After revealing the anti-cancer properties of boron, which is included in the category of essential elements for human health by the World Health Organization, the therapeutic potential of boron compounds has been begun to be evaluated, and its molecular effect mechanisms have still been among the research subjects. In ovarian cancer, mutations or amplifications frequently occur in the PI3K/Akt/mTOR pathway components, and dysregulation of this pathway is shown among the causes of treatment failure. In the present study, it was aimed to investigate the anti-cancer properties of boron-containing DPD in SKOV3 cells, which is an epithelial ovarian cancer model, through PI3K/AKT/mTOR pathway. The cytotoxic activity of DPD in SKOV3 cells was evaluated by WST-1 test, apoptotic effect by Annexin V and JC-1 test. The gene expressions associated with PI3K/AKT/mTOR pathway were determined by real-time qRT-PCR. In SKOV3 cells, the IC50 value of DPD was found to be 6.7 mM, 5.6 mM, and 5.2 mM at 24th, 48th and 72nd hour, respectively. Compared with the untreated control group, DPD treatment was found to induce apoptosis 2.6-fold and increase mitochondrial membrane depolarization 4.5-fold. DPD treatment was found to downregulate PIK3CA, PIK3CG, AKT2, IGF1, IRS1, MAPK3, HIF-1, VEGFC, CAB39, CAB39L, STRADB, PRKAB2, PRKAG3, TELO2, RICTOR, MLST8, and EIF4B genes and upregulate TP53, GSK3B, FKBP8, TSC2, ULK1, and ULK2 genes. These results draw attention to the therapeutic potential of DPD, which is frequently exposed in daily life, in epithelial ovarian cancer and show that it can be a candidate compound in combination with chemotherapeutics.

AIM: This multicenter investigation was performed to evaluate the adjuvant treatment options, prognostic factors, and patterns of recurrence in patients with grade 3 endometrioid endometrial cancer (G3-EEC). MATERIALS AND METHODS: The medical reports of patients undergoing at least total hysterectomy and salpingo-oophorectomy for G3-EEC between 1996 and 2018 at 11 gynecological oncology centers were analyzed. Optimal surgery was defined as removal of all disease except for residual nodules with a maximum diameter ≤ 1 cm, as determined at completion of the primary operation. Adequate systematic lymphadenectomy was defined as the removal of at least 15 pelvic and at least 5 paraaortic LNs. RESULTS: The study population consists of 465 women with G3-EEC. The 5-year disease-free survival (DFS) and overall survival (OS) rates of the entire cohort are 50.3% and 57.6%, respectively. Adequate systematic lymphadenectomy was achieved in 429 (92.2%) patients. Optimal surgery was achieved in 135 (75.0%) patients in advanced stage. Inadequate lymphadenectomy (DFS; HR 3.4, 95% CI 3.0-5.6; P = 0.016-OS; HR 3.2, 95% CI 1.6-6.5; P = 0.019) was independent prognostic factors for 5-year DFS and OS. CONCLUSION: Inadequate lymphadenectomy and LVSI were independent prognostic factors for worse DFS and OS in women with stage I-II G3-EEC. Adequate lymphadenectomy and optimal surgery were independent prognostic factors for better DFS and OS in women with stage III-IV G3-EEC.

The aim of this study was to investigate T-cell receptor (TCR) changes in ovarian carcinoma (OC). The study included 24 malignant and 23 benign adnexal masses. DNA was isolated from ovarian samples. Multiplex PCR was used to determine T-cell gene clonality. PCR products were loaded onto polyacrylamide gel electrophoresis and imaged. The relationship between prognostic parameters and T-cell rearrangement was evaluated. In the study group (SG), TCRB-B positivity was higher than control group (CG) and TCRD receptor positivity was higher in CG. In SG, TCRG-B levels were higher in patients with stage I-II tumours compared to stage III. TCRG-B receptor was higher in patients with overall survival of 36 months and above. In our study, subgroups of TCRs were analysed in OC. According to our findings, significant differences in TCRB-B and TCRD subgroups may be applied to immune therapies. Understanding of TCR pathways will provide new treatment approaches in OC.IMPACT STATEMENTWhat is already known on this subject? Ovarian cancer is the most challenging kind of gynaecologic cancer. Although the main route of spread is direct invasion and peritoneal spread in the abdominal cavity, lymphatic invasion is also very important. Recent studies put forward that immunological mechanisms play crucial role in ovarian cancer. CD3 and CD8 positive lymphocyte infiltration in ovarian tumour is related with better prognosis where, FoxP3 positive lymphocyte infiltration is a predictor of poor survival. Also, immune checkpoints and inhibitors are important topics in ovarian cancer.What the results of this study add? Despite all the improvements and studies regarding immune system and ovarian cancer, the role T-cell receptor (TCR) subtypes is not clear and there are very few number of studies in this area. This is one of the first studies that describe the rearrangement of TCR subtypes between normal ovarian tissue and ovarian cancer tissue.What the implications are of these findings for clinical practice and/or further research? Understanding the role of TCR subtypes has a key role because studies about lymphocyte infiltration in ovarian cancer varies from region to region in the world and same type of lymphocytes has different effects in different studies. Further studies on TCR subtypes may elucidate us about the behaviour of lymphocytes. Additionally, these receptor may be targeted if their roles are better understood.

AIM: The clinicopathologic characteristics, recurrence patterns, and survival of patients with grade 3 endometrial cancer (G3-EAC) and uterine carcinosarcoma (UCS) were compared. MATERIALS AND METHODS: The medical records of patients treated for G3-EAC and UCS between January 1996 and December 2016 at 11 gynecologic oncology centers in Turkey and Germany were analyzed. RESULTS: Of all patients included in the study, 161 (45.1%) were diagnosed with UCS and 196 (54.9%) with G3-EAC at FIGO stage I-II (early stage) disease. The recurrence rate was higher in patients with UCS than in those with G3-EAC (17.4 vs. 9.2%, p = 0.02). The 5-year disease-free survival (DFS; 75.2 and 80.8%, respectively; p = 0.03) and overall survival (OS; 79.4 and 83.4%, respectively; p = 0.04) rates were significantly lower in the UCS group compared to the G3-EAC group. UCS histology was an independent prognostic factor for decreased 5-year DFS (HR 1.8, 95% CI 1.2-3.2; p = 0.034) and OS (HR 2.7, 95% CI 1.3-6.9; p = 0.041) rates. CONCLUSIONS: The recurrence rate was higher in UCS patients than in G3-EAC patients, regardless of disease stage. DFS and OS were of shorter duration in UCS than in G3-EAC patients. Adequate systematic lymphadenectomy and omentectomy were an independent prognostic factor for increased 5-year DFS and OS rates.

Poly(acrylic acid/Kryptofix 23-Dimethacrylate) superabsorbent polymer [P (AA/Kry23-DM) SAP] was synthesized by solution polymerization to remove Co, Ni, Cu, Cd, Mn, Zn, Pb, Cr, and Fe ions in water and improve the quality of the water. Kry23-DM cross-linker (1,4,7,13,16-Pentaoxa-10,19 diazo cyclohexene icosane di methacrylate) was synthesized using Kry23 and methacryloyl chloride. The characterization of the molecules was done by FTIR, TGA, DSC, and SEM techniques. The effects of parameters such as pH, concentration, and the metal ion interaction on the heavy metal ions uptaking of SAP was investigated. It was observed that P (AA/Kry23-DM) SAP has maximum water absorption, and the absorption increases with the pH increase. Adsorption rates and sorption capacity, desorption ratios, competitive sorption (qcs), and distribution coefficient (log D) of P(AA/Kry23-DM) SAP were studied as a function of time and pH with the heavy metal ion concentration. Langmuir and Freundlich isotherms of the P (AA/Kry23-DM) SAP were investigated to verify the metal uptake. Molecular mechanic (MM2), Assisted Model Building with Energy Refinement (AMBER), and optimized potentials for liquid simulations (OPLS) methods. were used in quantum chemical calculations for the conformational analysis of the cross-linker and the SAP. ΔH0f calculations of the cross-linker and the superabsorbent were made using Austin Model 1(AM1) method.
ABSTRACT
Objective: Tadalafil is a selective phosphodiesterase type-5 inhibitor with a long half-life. It has a dual function in ischaemic and re-perfused tissues, i.e. vasodilatation and anti-oxidant effects. These features of tadalafil distinguish it from other anti-oxidants. We investigated the dual effect of tadalafil on ischaemia and reperfusion injury in the rat ovary. Material and Methods: We established five study groups. Group 1 (n=6): sham-operated; group 2 (n=6): torsion; group 3 (n=6): torsion and Tadalafil; group 4 (n=6): torsion/de-torsion; and group 5 (n=6): torsion/de-torsion and tadalafil. Ovarian samples were harvested from animals and evaluated in terms of histopathologic changes, tissue malondialdehyde (MDA) concentrations, lactate production, and plasma cyclic guanosine monophosphate (cGMP). Results: Follicular degeneration, oedema, haemorrhage, and inflammatory cells were significantly decreased in group 5 in comparison with group 4. Group 2 and group 3 were compared in terms of vascular congestion and haemorrhage; these parameters were significantly decreased in group 3. In addition, significantly decreased MDA and lactate concentrations were observed in group 5 in comparison with group 4. Increased cGMP concentrations were detected in group 3 and group 5. Conclusion: We conclude that tadalafil might be useful in protecting the ovary against ischaemia and reperfusion injury. In the evet of ovarian torsion, it will provide a greater therapeutic effect than only performing de-torsion of the ovary or using other anti-oxidant agents.
ABSTRACT
OBJECTIVES: To investigate gene expression differences and related functions between primary tumor, malignant cells in ascites, and metastatic peritoneal implant in high-grade serous ovarian cancer. METHODS: Biopsies from primary tumor, peritoneal implant, and ascites were collected from 10 patients operated primarily for high-grade, advanced-staged serous ovarian cancer. Total RNA isolation was performed from collected tissue biopsy and fluid samples, and RNA expression profile was measured. Messenger RNA expression profiles of 3 different groups were compared. Functional analyses of candidate genes were carried out by gene ontology and pathway analysis. RESULTS: There were significant differences in the expression of 5 genes between primary tumor and peritoneal implant, 979 genes between primary tumor and malignant cells in ascites, and 649 genes between peritoneal implant and malignant cells in ascites. Three commonly enriched gene ontology functions between "primary tumor and malignant cells in the ascites" and "peritoneal implant and malignant cells in the ascites" were protein deubiquitination, ubiquitin-dependent protein catabolism, and apoptotic processes. All genes related to these functions belonged to USP17 gene family. CONCLUSION: Gene expression difference between primary tumor and the peritoneal implant is not as much as the difference between primary tumor and free cells in the ascites. These results show that malignant cells in the ascites return into its genetic origin after they invade on the peritoneum. Significantly increased expression of DUB-enzyme genes, SNAR gene family, and ribosomal pathway genes in epithelial-mesenchymal transition suggests that this regulation is ubiquitin-proteasome dependent. Especially, this is the first study that offers USP17 as a potential target for epithelial-mesenchymal transition.

Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein commonly used in the field of medicine to treat neutropenia. Granulocyte colony-stimulating factor has also crucial roles in ameliorating the ischemia/reperfusion (I/R) injury in particular tissues. In this study, we aimed to investigate the protective effect of G-CSF on ovarian damage in experimental ovarian I/R injury. Thirty adult female rats were used. Rats were separated randomly into 5 groups; Group 1: sham group (abdominal wall was opened and closed surgically), Group 2: torsion group with 3-hour ischemia using vascular clips. Group 3: torsion + G-CSF group with 3-hour ischemia 30 minutes after the administration intraperitoneal (i.p.) of 100 µg/kg of G-CSF. Group 4: torsion-detorsion group with 3 hour ischemia and 3 hour reperfusion. Group 5: torsion-detorsion + G-CSF group with 3 hour ischemia followed by 100 µg/kg of G-CSF i.p. administration 30 minutes prior to 3 hour of detorsion/reperfusion. Ovarian tissue damage was scored on histopathology. Ovarian tissue malondialdehyde (MDA) was measured biochemically. In comparison with the sham group, both the torsion and torsion-detorsion groups had significantly higher scores for follicular degeneration, vascular congestion, edema, hemorrhage, and leukocyte infiltration (P < .05). When compared group torsion-detorsion + G-CSF to group torsion-detorsion, parameters aforementioned significantly decreased in group torsion-detorsion + G-CSF (P < .05). Granulocyte colony-stimulating factor has also decreased MDA levels notably both in the torsion + G-CSF and torsion-detorsion + G-CSF groups (P < .05, P < .01). Our experimental study suggests that G-CSF can be a novel agent for the treatment of ovarian I/R injury.

AIMS: The objective of this study is to identify the diagnostic performance of three-dimensional transvaginal ultrasonography (3D-US) and magnetic resonance imaging (MRI) in detecting myometrial, lower uterine segment and/or cervical invasion in endometrial cancer patients. MATERIALS AND METHODS: In this prospective study, 40 patients diagnosed with endometrial cancer were performed 3D-US and MRI, preoperatively. Deep myometrial, lower uterine segment and cervical invasion were evaluated subjectively and results were compared with the final histology as a gold standard. RESULTS: Diagnostic accuracy of 3D-US for detecting deep myometrial, lower uterine segment and cervical invasion were 87.5%, 80% and 85%, respectively. The same results for MRI were 75%, 65% and 70%, respectively. For deep myometrial, lower uterine segment and/or cervical invasion in endometrial cancer, 3D-US had higher sensitivity, specificity, negative and positive predictive value and accuracy than MRI. The combination of these two imaging techniques had an increased sensitivity of detecting all parameters related with tumoral invasion but decreased specificity and the accuracy. CONCLUSION: 3D-US had better performance in detecting myometrial, lower uterine segment and/or cervical invasion than MRI in endometrial cancer patients. Combination of these techniques was not preferred according to this study.

BACKGROUND: Ovarian torsion is one of the most common gynecological emergencies, which especially affects women of reproductive age. OBJECTIVES: We aimed to evaluate the effect of Ginkgo biloba (GB) supplementation in ovarian ischemia/ reperfusion injury in an experimental torsion/de-torsion rat model. MATERIAL AND METHODS: This study was carried out in the Ege University Faculty of Medicine in Izmir, Turkey. Thirty mature female Sprague-Dawley albino rats were randomly divided into 5 groups: in Group 1 (control), the abdominal wall was only opened and closed; in the torsion group (Group 2), ischemia was induced for 3 h, using atraumatic vascular clips to create a torsion model; in the torsion/GB group (Group 3), the rats were given 80 mg/kg (oral gavage) of GB 30 min before torsion was induced and the torsion model was formed; in the torsion/de-torsion group (Group 4), the rats underwent 3 h of ischemia and then the vascular clips were removed and reperfusion took place for 3 h; in the torsion/de-torsion/GB group (Group 5), the rats underwent 3 h of ischemia followed by GB (oral gavage) 30 min prior to a 3-h reperfusion period. Ovarian tissue damage was evaluated by a histopathological scoring system. Ovarian tissue malondialdehyde (MDA) and plasma pentraxin-3 were measured. RESULTS: In comparison with the sham group, both the torsion and torsion/de-torsion groups had significantly higher scores for follicular degeneration, vascular congestion, edema, hemorrhage, and leukocyte infiltration. Ginkgo biloba significantly decreased these scores in both groups. Ovarian malondialdehyde and plasma pentraxin 3 were significantly higher both in the torsion and torsion/de-torsion groups compared with the sham group. Ginkgo biloba decreased these levels significantly both in the torsion/GB and torsion/de-torsion/GB groups. CONCLUSIONS: Supplementing GB during a surgical procedure decreases ischemia/reperfusion injury to an ovary in an experimental rat model based on histopathological parameters, tissue malondialdehyde, and plasma pentraxin-3 levels.

The aim of this study is to present a rare case of Müllerian adenosarcoma of the cervix with ovarian metastasis and sarcomatous overgrowth. A gravida 2, para 2 woman aged 32 years with vaginal bleeding was admitted to the gynecology department. A 3-4 cm polypoid mass protruding from the cervix was detected in a pelvic examination. Total abdominal hysterectomy and bilateral salpingoopherectomy was performed because of metastatic implants on the right ovary. The pathologic evaluation revealed Müllerian adenosarcoma of the cervix with sarcomatous overgrowth and ovarian metastasis. After surgery, the patient was planned to undergo chemo- and radiotherapy. This is the first cervical Müllerian adenosarcoma case mentioned in the literature with metastasis to the ovary in a young woman. There is no optimal management option for cervical adenosarcomas due to the rarity of this phenomenon. Nevertheless, even if the patient is young and imaging techniques do not elucidate metastatic disease, surgeons should evaluate the ovaries for the spread of tumor, especially if histology reveals sarcomatous overgrowth.
ABSTRACT
BACKGROUND/AIM: The purpose of this study was to prove the effect of complete surgical staging of patients with mucinous borderline ovarian tumors (mBOTs) especially appendectomy on progression-free survival (PFS) and overall survival (OS). PATIENTS AND METHODS: The database of 14 gynecological oncology departments from Turkey and Germany were comprehensively searched for women who underwent primary surgery for an ovarian tumor between January 1, 1998, and December 31, 2015, and whose final diagnosis was mBOT. RESULTS: A total of 364 patients with mBOT with a median age of 43.1 years were included in this analysis. The median OS of all patients was 53.1 months. The majority of cases had Stage IA (78.6%). In univariate and multivariate analyses, radical surgery, omentectomy, appendectomy, lymphadenectomy, and adding adjuvant chemotherapy were not independent prognostic factors for PFS and OS. Furthermore, FIGO stage (≥IC vs. Subject(s)

ABSTRACT
OBJECTIVE: The aim of this study is to evaluate the impact of lymphocyte infiltration on prognostic parameters, recurrence and survival in ovarian cancer. STUDY DESIGN: Sixty-two patients who were primarily operated for epithelial ovarian carcinoma between 1997 and 2008 were included. CD3, CD4, CD8, CD20 and FoxP3 expressions were evaluated immunohistochemically on sections obtained from paraffin-embedded tissues. RESULTS: Median follow up was 87 months. In whole cohort, CD3+ and CD8+ T lymphocyte infiltrations were significantly higher in patients with high-grade tumors, advanced stage tumors and the patients with omental metastasis (for CD3 p=0.0001, p=0.029, p=0.016; for CD8 p=0.044, p=0.002, p=0.046, respectively). DFS was significantly lower among patients with CD8+ T lymphocytes with regard to patients who did not have CD8+ T lymphocyte infiltration (p=0.028). In univariate analysis, presence of CD8 cytotoxic T lymphocyte infiltration (p=0.03), stage (0.0001), tumor grade (p=0.007), omental metastasis (p=0.0001) and lymph node metastasis (p=0.0001) were significant risk factors for recurrence. But in multivariate analysis, only stage [HR: 116.6 (95% CI: 13.09-1039.45) (p=0.0001)] was found as an independent risk factor for recurrence. CONCLUSION: CD3+ and CD8+ T lymphocyte infiltrations were related with advanced stage, high-grade tumor and the omental metastasis in ovarian cancer. DFS was significantly shorter in patients with CD8+ T lymphocyte infiltration. CD3+ and CD8+ T lymphocyte infiltrations were related with poor prognosis in ovarian cancer.

OBJECTIVE: To survey experience with the first-trimester combined test (FCT) for trisomy 21 (T21) in different risk score groups to determine the most useful clinical application of cell-free fetal DNA (cffDNA) screening. METHODS: In a retrospective study, the records of FCT results obtained at a center in Turkey between January 2009 and January 2014 were reviewed. The FCT results and rates of uptake of invasive diagnostic testing were compared among different risk score groups. RESULTS: FCT results were available for 4804 pregnancies; 276 (5.7%) had IDT results. Ten (72.7%) of 11 cases of T21 had a risk score of 1:300 or more. The IDT uptake rates were 54.5%, 51.9%, and 47.4% at risk scores of 1:100 or more, 1:200 or more, and 1:300 or more, respectively. In the group at intermediate risk (1:1001-1:3000), no pregnancy had an FCT result of both low pregnancy-associated plasma protein A and high free ß-human chorionic gonadotropin, but 30 (3.9%) of 766 pregnancies had both advanced maternal age and high ß-human chorionic gonadotropin. CONCLUSION: cffDNA screening should be used to optimize IDT uptake in pregnancies with a risk score of 1:101-1:1000. The selective power of the FCT diminishes beyond the 1:1001 score and cffDNA screening cannot yet be recommended routinely.

The aim of this study was to identify the role of preoperative serum vascular endothelial growth factor (VEGF) and migration inhibitor factor (MIF) in differentiation of benign and malignant adnexal masses, as well as the relationship between prognostic factors and VEGF and MIF in ovarian cancer patients. This prospective study included 41 patients who were admitted between November 2010 and March 2012. In the malignant group, there were 21 patients, and remaining 20 had benign adnexal masses. Age, CA125 levels, grade, stage, presence of ascites and the degree of cytoreduction performed were noted. There was no significant difference between two groups in preoperative serum VEGF and MIF levels (p = 0.118 and p = 0.297, respectively). CA125 levels were significantly higher in the malignant group (p < 0.0001). There was no significant difference for VEGF and MIF between the groups evaluated for tumour grade, stage, presence of ascites and degree of cytoreduction performed in the malignant group. Preoperative serum, VEGF and MIF levels are not suitable for the differentiation of malignant and benign adnexal masses, and they do not correlate with the prognostic factors of ovarian cancer in this cohort of patients.

OBJECTIVE: The objective of this study is to determine the efficiency of YKL-40, HE-4 and DKK-3 levels in early diagnosis of patients with endometrial cancer and in the pre-operative estimation of the prognostic parameters such as stage, grade and the extension of the disease. METHODS: In this prospective study, 50 patients diagnosed with endometrial cancer and 50 women as a control group, who applied to Dokuz Eylul University and Ege University Faculties of Medicine, Obstetrics and Gynecology Clinics between May 2011-May 2012 were included. CA125, HE-4, YKL-40 and DKK-3 serum levels were measured by ELISA and compared between two groups. The relation between serum levels and histopathological results, extension of disease and prognostic factors were analyzed. RESULTS: Preoperative serum CA125, HE-4 and YKL-40 levels were significantly higher in endometrial cancer group (p<0.001). Serum HE-4 levels were significantly higher in advanced stages (p=0.004). When we examined early stage patients, YKL-40 levels were significantly higher in non-endometrioid histology compared with endometrioid adenocarcinoma (p=0.022). We also examined the relation between the markers and prognostic factors. Different from other markers, HE-4 levels were significantly higher in endometrial cancer patients who had lymphovascular space involvement, lower uterine segment involvement, endocervical stromal involvement, and deep myometrial invasion. CONCLUSION: YKL-40 and HE-4 were significantly higher in patients with endometrial cancer. HE-4 seems to be superior to YKL-40 in discriminating early and advanced stages. Additionally, HE4 is significantly correlated with prognostic factors. HE-4 and YKL-40 may be successful in early determination of endometrial cancer and in detection of high risk subsets before surgery.

AIM: This study investigated the efficacy of octreotide for prevention of ischemia-reperfusion injury in rat ovary. METHODS: Thirty-two adult female rats were included. Rats were divided into five groups: in the sham group, the abdominal wall was only opened and closed; in the torsion group, ischemia was induced for 3 h using a torsion model involving atraumatic vascular clips; in the torsion/octreotide group, rats were given 100 µg/kg i.p. octreotide 30 min before torsion was induced; in the torsion/detorsion group, rats underwent 3 h ischemia-3 h reperfusion; in the torsion/detorsion/octreotide group, rats underwent 3 h ischemia followed by 100 µg/kg octreotide i.p. 30 min prior to 3 h reperfusion. Ovarian tissue damage was scored on histopathology. Ovarian tissue malondialdehyde and plasma pentraxin 3 were measured biochemically. RESULTS: In comparison with the sham group, both the torsion and torsion/detorsion groups had significantly higher scores for follicular degeneration, vascular congestion, edema, hemorrhage and leukocyte infiltration. Octreotide significantly decreased these scores in both groups. Ovarian malondialdehyde and plasma pentraxin 3 were significantly higher both in the torsion and torsion/detorsion groups compared with the sham group. Octreotide also decreased these levels significantly both in the torsion/octreotide and torsion/detorsion/octreotide groups. CONCLUSION: Octreotide ameliorated the potential side-effects of ovarian ischemia-reperfusion injury in a rat model.

INTRODUCTION: By looking through our ethical committee cases, we demonstrate the main arguments we use for making a judgment in face of fetal abnormalities. Our decision making model is a simplified algorithm of the arguments and concepts we use in scientific-ethic discussion. MATERIALS AND METHODS: A retrospective analysis was conducted from single, tertiary referral center of patients evaluated for fetal abnormalities from 2004 to 2014. We hypothesized that all our judgments would fit into a decision-tree model. RESULTS: 553 fetal abnormality cases were discussed, 348 (63%) were given termination of pregnancy (TOP) proposal. When detected <24 weeks, fetuses with chromosomal abnormality/genetic disorders (n:100) and with mental retardation risk (n:93) ended up with TOP proposal. For incompatibility with life cases (n:111) and the multimorbidity cases (n:44) the committee suggest TOP, regardless of gestational age. The highest family approval ratios were in chromosomal abnormalities/genetic disorders group (93%), and the lowest figures were in mental retardation risk group (80%). DISCUSSION: Continuously changing literature on prenatal and postnatal therapy options and the long term outcome of various fetal abnormalities influence committee decisions. Theoretical high success rates and inconsistent data on long term prognosis of some anomaly groups resulted in heterogenous decisions and various approval ratios.
