A rare case of primary ovarian mesonephric adenocarcinoma and a review of the literature.

OBJECTIVE: Are reported in the cervix in the female genital tract, has been reported in very few studies in the literature. In this report, we aimed to present a case with mesonephric carcinoma, which was detected in the ovary and is very rarely seen. CASE REPORT: In a case since the frozen section results of the left adnexal mass were reported as malignant. CONCLUSION: Ovarian mesonephric carcinoma is very rare and exhibits very different morphological patterns. Therefore, immunohistochemical and morphological findings should be evaluated together. If the pathological picture does not fit the common carcinomas of ovarian origin and this entity must be brought to mind, because, if these tumors with different molecular developmental pathways are diagnosed correctly, treatment schemes will change and targeted therapies will be developed too. KEY WORDS: Mesonephric carcinoma, Mesonephric like carcinoma, Ovarian carcinoma.

Survival outcomes of women with grade 3 endometrioid endometrial cancer: the impact of adjuvant treatment strategies.

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.

Is the Oncological Outcome of Early Stage Uterine Carcinosarcoma Different from That of Grade 3 Endometrioid Adenocarcinoma?

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.

Potential biomarker of circulating hsa-miR-1273g-3p level for detection of recurrent epithelial ovarian cancer.

PURPOSE: Ovarian cancer (OC) is first gynaecologic cancer that causes women death and epithelial ovarian cancer (EOC) is the most lethal ovarian cancer type. While treatment is commonly successful, some cases (10-20%) show resistance to chemotherapy which is followed by recurrence. MicroRNA (miRNA) based diagnosis methods are slightly important for recurrent ovarian cancer diagnosis. We aimed to detect novel circulating miRNAs to be used as an early diagnosis and prediction tools for recurrent EOC. METHODS: In this study, recurrent EOC serum samples and healthy control serum samples were compared for miRNA expression analysis by microarray. Microarray results were analyzed by bioinformatics tools and differentially expressed hsa-miR-1273g-3p was obtained. After microarray analysis, differentially expressed hsa-miR-1273g-3p was validated by Real-Time PCR (RT-qPCR). The relation between target genes of hsa-miR-1273g-3p and ovarian cancer were examined by Pathway Studio® (v.11.4.0.8). RESULTS: The expression of hsa-miR-1273g-3p was found to be significantly down-regulated by t test Bonferroni FWER corrected p < 0.05 and fold change > 2, in recurrence EOC compare with healthy controls groups. The RT-qPCR results confirmed that relative expressions of the serum hsa-miR-1273g-3p were significantly down-regulated in patients with recurrent EOC (p = 0.0275). Serum hsa-miR-1273g-3p levels could discriminate patients with recurrent EOC from healthy controls, with a power area under the curve (AUC) of 0.7. CONCLUSION: This study suggested that hsa-miR-1273g-3p plays a significant role in regulation of related genes, which are TNF-alfa, COL1A1, MMP-2, MMP-9, with recurrent EOC outcome. hsa-miR-1273g-3p may be used as a prognostic marker for recurrent EOC after chemotherapy.

Which factors are associated with the recurrence of endometrioma after cystectomy?

Endometrioma is the most common form of endometriosis and is a sign of wide-spread disease in symptomatic patients. Medical treatment options can be successful in endometrioma smaller than 1 cm, but ineffective for growing and symptomatic endometriomas. Conservative surgical interventions that preserve fertility, such as laparoscopic removal or destruction of endometriotic tissue or aspiration of cystic content are typically used to treat the condition. One of the most frustrating aspects of endometrioma treatment is disease recurrence. The underlying mechanisms explaining recurrence are uncertain. Several risk factors have been evaluated in order to predict recurrence after cystectomy. In looking at the results overall, our study can conclude that the presence of greater cyst dimension, higher CA-125 level, presence of preoperative symptoms of non-cyclic pelvic pain, dysmenorrhoea and adhesion extension may be associated with recurrent endometrioma. In clinical practice, identification of risk factors for recurrence helps clinicians to inform patients. Impact statement What is already known on this subject: Endometrioma is the most common form of endometriosis and is a sign of wide-spread disease in symptomatic patients. One of the most frustrating aspects of endometrioma treatment is disease recurrence. Several risk factors have been evaluated in order to predict recurrence after cystectomy. However, the risk factors have not been precisely defined. What the results of this study add: This study aimed to investigate the contribution of possible risk factors to the recurrence of endometrioma after laparoscopic surgery. In looking at the results overall, our study can conclude that the presence of greater cyst dimension, higher CA-125 level, adhesion extension, presence of preoperative symptoms of non-cyclic pelvic pain and dysmenorrhoea may be associated with recurrent endometrioma. What the implications of these findings are for clinical practice and/or further research: In clinical practice, identification of risk factors for recurrence helps clinicians to inform patients. Detection of preoperative risk factors would be helpful in counselling patients on their future prognosis. This may also increase treatment success by providing accurate preoperative treatment planning and by assisting the scheduling of postoperative follow-ups.

The Impact of Surgical Staging on the Prognosis of Mucinous Borderline Tumors of the Ovaries: A Multicenter Study.

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.

Misinterpretation of Frozen Section in Endometrial Cancer Cases: Does It Have Any Effect on Disease-free and Overall Survival?

The aim of this study was to assess whether misinterpretation of frozen sections in endometrial cancer cases is associated with survival and determine the factors leading to mismatch. One hundred fifty endometrial cancer cases treated in Zeynep Kamil Maternity and Children's Health Training and Research Hospital between January 2010 and December 2014 were included in the study. Frozen sections and final histopathologic reports were screened from a prospectively collected database and analyzed on whether mismatch between the initial and the final reports has any impact on disease-free survival. There were 31 patients with mismatched frozen sections with the final report, whereas in 119 patients, frozen sections and final reports were consistent. The recurrence-free survival time was similar between groups (51 vs. 49, P=0.813). Overall survivals were also similar between groups (55 vs. 52, P=0.880). Frozen section misinterpretation does not affect disease-free and overall survival in endometrial cancer cases.

Borderline ovarian tumors: clinical characteristics, management, and outcomes - a multicenter study.

BACKGROUND: The optimal surgical management and staging of borderline ovarian tumors (BOTs) are controversial. Institutions have different surgical approaches for the treatment of BOTs. Here, we performed a retrospective review of clinical characteristics, surgical management and surgical outcomes, and sought to identify variables affecting disease-free survival (DFS) and overall survival (OS) in patients with BOTs. METHODS: A retrospective review of ten gynecological oncology department databases in Turkey was conducted to identify patients diagnosed with BOTs. The effects of type of surgery, age, stage, surgical staging, complete versus incomplete staging, and adjuvant chemotherapy were examined on DFS and OS. RESULTS: In total, 733 patients with BOTs were included in the analysis. Most of the staged cases were in stage IA (70.4 %). In total, 345 patients underwent conservative surgeries. Recurrence rates were similar between the conservative and radical surgery groups (10.5 % vs. 8.7 %). Furthermore we did not find any difference between DFS (HR = 0.96; 95 % confidence interval, CI = 0.7-1.2; p = 0.576) or OS (HR = 0.9; 95 % CI = 0.8-1.1; p = 0.328) between patients who underwent conservative versus radical surgeries. There was also no difference in DFS (HR = 0.74; 95 % CI = 0.8-1.1; p = 0.080) or OS (HR = 0.8; 95 % CI = 0.7-1.0; p = 0.091) between complete, incomplete, and unstaged patients. Furthermore, receiving adjuvant chemotherapy (CT) for tumor stage ≥ IC was not an independent prognostic factor for DFS or OS. CONCLUSIONS: Patients undergoing conservative surgery did not show higher recurrence rates; furthermore, survival time was not shortened. Detailed surgical staging, including lymph node sampling or dissection, appendectomy, and hysterectomy, were not beneficial in the surgical management oF BOTs.

Comparison of Two Step LEEP and Cold Conisation For Cervical Intraepithelial Lesions to Decrease Positive Surgical Margins.

PURPOSE: To assess the success rates of two step loop electrosurgical excision procedure (LEEP) compared with conventional cold conization procedures for decreasing positive surgical margins. MATERIALS AND METHODS: This study was conducted on 70 patients who underwent colposcopic evaluation in Zeynep Kamil Women and Children's Health Training and Research Hospital between 20132015 with indications of CIN 2/3 or persistent CIN 1 for more than 2 years. The study included age matched groups of patients with similar histopathololical lesions who underwent cold conization (n=40) or LEEP (N=30). RESULTS: Comparison of tissue characteristics between the two groups revealed significantly higher deepest depth and lower volume of tissue removed by the two step LEEP. Ectocervical positivity rate was similar between groups (1/39 versus 0/29, P>0.05), while endocervical surgical margin positivity rate was significantly higher in the cold conization group (9/39 versus 0/29, P<0.05). Surgical margin positive cases were significantly older than the cases with negative margins (P<0.05). CONCLUSIONS: Two step LEEP made it easier to reach the squamocolumnar junction in the endocervical region with lower blood loss and applicability in office settings. Our study suggests to use two step approach in cases with high grade and glandular CIN.

Area under curve of temporal estradiol measurements for prediction of the detrimental effect of estrogen exposure on implantation.

OBJECTIVE: To assess whether the area under the curve of temporal estradiol measurements (AUCEM) during cycles of assisted reproductive technology (ART) can be used to predict failure of implantation and clinical pregnancy. METHODS: In a prospective study, women aged 24-39years undergoing ART at a center in Turkey were enrolled between January and December 2014. Eligible patients had a regular menstrual cycle, normal levels of serum prolactin, and no hormone treatment within the past 3months. The area under the curve of the time course of estradiol measurements was calculated for each participant, and assessed for its ability to predict successful implantation. RESULTS: Among 282 participants, 109 (38.6%) women had successful implantation. There was a significant difference between the two groups of women in AUCEM, estradiol per day (AUCEM divided by duration of stimulation), and endometrial thickness on the day of human chorionic gonadotropin administration (P<0.05 for all). CONCLUSION: The area under the curve of estradiol measurements during ART cycles might be useful for predicting failure of implantation and clinical pregnancy.

Evaluation of the maternal and fetal risk factors associated with neonatal care unit hospitalization time.

OBJECTIVE: To evaluate maternal and neonatal risk factors associated with the length of hospital stay in the neonatal intensive care unit (NICU). MATERIAL AND METHOD: This retrospective observational study was based on 3607 newborns who were admitted to the NICU of a tertiary teaching hospital from January 2012 through December 2014. Known obstetric risk factors associated with duration of hospitalization in NICUs were assessed including intrauterine growth restriction, maternal diabetes, oligohydramnios, chorioamnionitis, premeture rupture of membranes, preeclampsia, congenital malformations, neonatal sepsis, premature retinopathy, intracranial bleeding, necrotizing enterocolitis, meconium aspiration, maternal hypertension, fetal congenital cardiac malformations, congenital metabolic diseases, congenital hypothyroidism, pneumonia, pulmonary hypertension, bronchopulmonary dysplasia, pneumothorax and respiratory distress syndrome. RESULTS: Gestational age (beta coefficient: -0.244, p<0.001) and birth weight (beta coefficient: -0.237, p<0.001) were significant confounders for duration of hospitalization in newborns. CONCLUSION: Gestational age and the birth weight were the most important confounders for duration of hospitalization. Neonate care in developing countries would further benefit from additional large population-based long-term studies with broad parameters.

Giant leiomyosarcoma: A case report.

INTRODUCTION: Uterine leiomyosarcoma is a rare uterine malignancy. Most of the patients lack symptoms or present with a rapidly enlarging pelvic mass. PRESENTATION OF CASE: We report on a very large leiomyosarcoma in a woman presenting with a 3 months history of rapidly growing adominal mass and fatigue. Laparotomy was performed and diagnosis was confirmed by pathologic and histologic analysis. Patient refused chemotherapy after surgery and died from recurrence at 4th postoperative month. DISCUSSION: Uterine leiomyosarcomas may follow a rapid clinical course with a doubling time of four weeks. There is no reliable method to distinguish uterine sarcoma from benign leiomyomas preoperatively. CONCLUSION: This case represents the largest leiomyosarcoma reported in the literature.

Comparison of the Effect of Laparoscopic and Abdominal Hysterectomy on Lower Urinary Tract Function, Vaginal Length, and Dyspareunia: A Randomized Clinical Trial.

OBJECTIVES: The effect of hysterectomy on vesicourethral and sexual functions remains controversial. The primary objective of this study was to compare the effects of a laparoscopic hysterectomy and a total abdominal hysterectomy on lower urinary tract function. The secondary aims were to compare the two surgeries in terms of postoperative vaginal length and dyspareunia. MATERIALS AND METHODS: This was a prospective randomized clinical study in which 292 women were assigned to either the laparoscopic hysterectomy (n = 146) or total abdominal hysterectomy (n = 146) groups. The vaginal length and urodynamic measurements were taken, and the patients were asked to grade the presence and severity of dyspareunia using a visual analog scale 3 weeks before and 12 weeks after the surgery. The relationship between the postoperative vaginal length and the incidence of dyspareunia was evaluated. The urodynamic procedures used included uroflowmetry and voiding cystometry to record the maximum flow rate (Q-max) and to assess the bladder capacity. RESULTS: The preoperative vaginal length was similar between the groups, whereas the postoperative vaginal length was significantly longer in the laparoscopic hysterectomy group. When the 15 patients who developed postoperative dyspareunia were evaluated, no differences in the postoperative vaginal length were seen, but a significant difference in the change in the length of the vagina was found when compared with the other patients. No significant difference was found with regard to pre- and postoperative Q-max, bladder capacity, and change in bladder capacity between the study groups. CONCLUSIONS: The change in the length of the vagina was much more remarkable after total abdominal hysterectomy, compared with laparoscopic hysterectomy. It seems that the Q-max and the bladder capacity increase after hysterectomies, regardless of the surgical type. Further prospective randomized comparative studies are warranted to ascertain whether laparoscopic hysterectomies cause less damage to the pelvic floor, compared with abdominal hysterectomies.

Shorter the cervix, more difficult the placenta percreta operations.

BACKGROUND: To determine the impact of cervical length (CL) on the clinical outcome of patients undergoing peripartum hysterectomy due to placenta previa/percreta. OBJECTIVE: To assess the association of CL with clinical outcomes in such patients. METHODS: We analyzed the data of patients who were diagnosed with anterior placenta previa/percreta prenatally and subsequently underwent peripartum hysterectomy at our tertiary care institution between 2004 and 2014. The sonographic images and measurements of CL were obtained from prospectively collected database. The duration of operation, units of blood products transfused, and length of stay in the hospital were recorded. Patients were stratified according to CL, and receiver-operating characteristics curves were used to determine the cut-off length for identification of patients at high risk of intra-operative difficulty. RESULTS: Sixty-one patients were included in this study. Number of packages of ES were correlated with the the duration of operation (r = 0.666, p < 0.001) and the CL (-0.793, p < 0.001). Number of packages of fresh frozen plasma was significantly correlated with the CL (-0.642, p < 0.001) and the duration of operation (r = 0.606, p < 0.001). Gestational age (AUC = 0.683, p = 0.014) and the CL (AUC = 0.980, p < 0.014) were significant predictors for the number of ES transfused > 4 packages. The cut-off value of four packages was determined according to the median level of packages transfused. Optimal cut-off value for the CL to predict transfusion ≤ 4 packages was 20.5 with 93% sensitivity and the 99% specificity. CONCLUSIONS: Short cervix appears to be a cause of difficulty in placenta previa/percreta operations. CL may also help in determining the timing of delivery in placenta percreta patients.

Tumor Diameter for Prediction of Recurrence, Disease Free and Overall Survival in Endometrial Cancer Cases.

AIMS: To analyse the predictors of recurrence, disease free survival and overall survival in cases with endometrial cancer. MATERIALS AND METHODS: A total of 152 women diagnosed with endometrial cancer were screened using a prospectively collected database including age, smoking history, menopausal status, body mass index, CA125, systemic disorders, tumor histology, tumor grade, lymphovascular space invasion, tumor diameter, cervical involvement, myometrial invasion, adnexal metastases, positive cytology, serosal involvement, other pelvic metastases, type of surgery, fertility sparing approach to assess their ability to predict recurrence, disease free survival and overall survival. RESULTS: In ROC analyses tumor diameter was a significant predictor of recurrence (AUC:0.771, P<0.001). The optimal cut off value was 3.75 with 82% sensitivity and 63% specificity. In correlation analyses tumor grade (r=0.267, p=0.001), tumor diameter (r=0.297, p<0.001) and the serosal involvement (r=0.464, p<0.001) were found to significantly correlate with the recurrence. In Cox regression analyses when some different combinations of variables included in the model which are found to be significantly associated with the presence of recurrence, tumor diameter was found to be a significant confounder for disease free survival (OR=1.2(95 CI,1.016-1.394, P=0.031). On Cox regression for overall survival only serosal involvement was found to be a significant predictor (OR=20.8 (95 % CI 2.4-179.2, P=0.006). In univariate analysis of tumor diameter > 3.75 cm and the recurrence, there was 14 (21.9 %) cases with recurrence in group with high tumor diameter where as only 3 (3.4 %) cases group with smaller tumor size (Odds ratio:7.9 (95 %CI 2.2-28.9, p<0.001). CONCLUSIONS: Although most of the significantly correlated variables are part of the FIGO staging, tumor diameter was also found to be predictor for recurrence with higher values than generally accepted.

Laparoscopic staging of endometrial cancer: Does it have any impact on survival?

OBJECTIVE: To assess whether laporoscopic approach to endometrial cancer is associated with survival. MATERIALS AND METHODS: In total, 158 patients with endometrial cancer underwent staging surgery at a tertiary referral center, 30 of whom underwent laparoscopy, whereas the remainder received treatment with a conventional approach. Survival between groups was analyzed. RESULTS: The comparison of the groups revealed similar disease-free survival (p=0.791). Histology, cervical, adnexal and serosal involvement were found to be significantly correlated with recurrence in the laparoscopically staged group, whereas CA 125, histology, tumor grade, tumor diameter, cervical involvement, degree of myometrial invasion, adnexal and serosal involvement, and pelvic metastasis were significanly correlated with recurrence in the conventionally managed group. CONCLUSION: Laparoscopic approach to endometrial cancer, along with its widely accepted postoperative advantages, has similar disease-free survival but different variables affect recurrence rates.

Five cases of non-hodgkin B-cell lymphoma of the ovary.

The involvement of the ovary in lymphomatous process is rare. Such an involvement may occur in 2 ways, primary or secondary. We report 5 cases of ovarian non-Hodgkin's lymphoma, with 3 of which primarily arising in the ovaries. Ovarian lymphoma can mimic more frequently occurring tumors including advanced epithelial carcinoma and radical surgery may be performed instead of a biopsy. The immunophenotypic and clinicopathologic features exhibited in this small series are described to call attention to early diagnosis and treatment of ovarian lymphoma. All patients were diagnosed as having DLBCL after ovary biopsy. Different treatment modalities were used and prognosis of the patients was reported.
