OBJECTIVE To investigate the effect of laparoscopic endometrioma stripping on serum antimüllerian hormone (AMH) and the correlation between the clinicopathologic factors. DESIGN Prospective study. SETTING University hospital. PATIENT(S) Sixty-five women with endometriomas. INTERVENTION(S) All patients underwent laparoscopic cystectomy. Serum AMH, FSH, LH, E(2), and antral follicle count (AFC) were measured preoperatively, at 6 weeks, and at 6 months postoperatively. Specimens were analyzed histopathologically. MAIN OUTCOME MEASURE(S) The primary end point was to assess the ovarian reserve damage based on alterations of AMH and the secondary end point was to detect the changes in FSH, LH, E(2), and AFC. RESULT(S) Serum AMH decreased significantly at the sixth month (61%) postoperatively. The FSH level increased significantly at the sixth week, but returned to normal at the sixth month. The AFC increased significantly at the sixth week and at the sixth month. The AMH level decrease was more evident in patients with the cyst <5 cm (65.7% vs. 41.3%). The AMH decrease was more in bilateral compared with unilateral endometriomas (67% versus 57%, respectively). No correlation was detected between the histopathologic analyses and tAMH level. Initially the AMH level was the only independent factor affecting the AMH decrease (odds ratio, 3.68; 95% confidence interval 1.66-8.14). CONCLUSION(S) Laparoscopic cystectomy of ovarian endometriomas causes a significant and progressive decline in serum AMH levels.

OBJECTIVE To evaluate the prognostic value of tumor budding (TB) in endometrioid (EEC) and non-endometrioid endometrial cancers (NEEC) and to determine its correlation with expression of E-cadherin. METHODS Ninety-five patients with primary endometrial carcinoma were examined statistically. All patients were diagnosed, treated, and given follow-up care at Dokuz Eylul University Faculty of Medicine. Tumor budding detected by either H&E-stained sections and anticytokeratin-staining C11. The tissue block with the largest invasive front was chosen for budding counting and immunostaining. E-cadherin expression was examined by immunohistochemistry using the primary antibodies against to it. RESULTS Tumor budding was low-grade in 73 and high-grade in 22 cases. E-cadherin expression loss was identified in 48 patients. The high-grade TB was significantly higher in patients with advanced stage and deep myometrial invasion (p=0.032 and 0.018, respectively). E-Cadherin expression was significantly lower in NEECs than EECs (p=0.032). The negative expression of E-cadherin was associated with advanced stage and poor differentiation (p=0.001 and p=0.024, respectively). We determined that tumor budding adversely correlated with the presence of E-cadherin expression but not statistically significant. Based on the results of multivariate analysis, TB has an independent impact on cumulative overall survival. We found no statistically significant difference between E-cadherin expression and survival. CONCLUSIONS TB is associated with undifferentiated tumor, advanced stage and decreased postoperative survival in endometrial cancer. It might be a valuable prognostic clinicopathologic factor which can be applicable in routine examination.

Abstract Our aim was to investigate the effects of antivascular endothelial growth factor (anti-VEGF) antibody Bevacizumab on endometrial explants and on apoptotic gene expression levels in the rat endometriosis model. Endometriotic implants were surgically formed, and rats treated with (i) 1 mg/kg single subcutaneous injection of depot leuprolide acetate; (ii) 2.5 mg/kg of single intaperitoneal injection of bevacizumab; (iii) intraperitoneal injection of saline. Histopathologic scores and adhesion scores of endometriotic foci and levels of Bcl-2-associated X protein (Bax), Cytochrome c (Cyt-c), B-cell lymphoma/ leukemia 2 (Bcl-2) and B-cell lymphoma-extra large (Bcl-xl) mRNA gene expressions of endometriotic foci. Bevacizumab treatment decreased the endometriotic explant size compared with control. Bevacizumab-treated rats had lower total adhesion scores when compared with the control group. Semiquantitative evaluation of the persistence of endometrial epithelial cells in the explants showed a lower score in gonadotropin-releasing hormone (GnRH) agonist-treated rats compared with control rats. In Bevacizumab increased expression of Bax 3.1-fold, Cyt-c 1.3-fold and decreased expression of Bcl-2 0.4-fold, Bcl-xl 0.8-fold compared with the control group. The GnRH agonist increased expression of Bax 3.0 fold, Cyt-c 1.3 fold and decreased expression of Bcl-2 0.4-fold, Bcl-xl 0.8-fold, compared with the control group. This study suggests that a novel angiogenesis inhibitor, anti-VEGF antibody bevacizumab is as effective as GnRH agonist in the regression of the endometriotic lesions in rat endometriosis model. One possible mechanism of this effect is the induction of apoptosis.

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.

Objective To determine matrix metalloproteinase-2 and survivin expressions in endometrial cancers, their relation to clinical and histologic parameters and to investigate any difference in the expression of these markers between endometrioid and nonendometrioid cancers. Methods Ninety-five patients with endometrial cancer, were included. Matrix metalloproteinase-2 and survivin expressions were analyzed immunohistochemically from paraffin-embedded tissues by using specific monoclonal antibodies. Results Survivin nuclear expression was higher in endometrioid cancer as compared to nonendometrioid cancer (p=0.040), but there was no difference for cytoplasmic survivin and matrix metalloproteinase-2 expressions between type I and type II carcinomas. Survivin cytoplasmic staining was significantly lower in patients with deep myometrial invasion (p=0.038). Nuclear expression of survivin is decreased in histologic grade 3 tumors compared to grade 1 and 2 tumors (p=0.013), but there is no difference between grade 1 and 2. We did not find any statistically significant difference between survivin or matrix metalloproteinase-2 expressions and survival. Conclusion Survivin and matrix metalloproteinase-2 are present in endometrioid and nonendometrioid cancers. Grade 1 and 2 tumors and carcinomas having myometrial invasion less than 50% have higher survivin expression. These results supports that, survivin may play an important role in early stage tumors and early phases of tumor development. We did not find any association between matrix metalloproteinase-2 expression and classical prognostic factors in endometrial cancer and both proteins were not associated with survival.

OBJECTIVE To compare the results of total laparoscopic hysterectomy and total abdominal hysterectomy in morbidly obese women with early stage endometrial cancer. MATERIAL AND METHODS This prospective study was conducted on 140 morbidly obese women with body mass indices ≥35 kg/m(2) and presenting with clinical stage 1 endometrial cancer. The patients underwent total laparoscopic hysterectomy (n=70) or total abdominal hysterectomy (n=70), bilateral salpingo-oophorectomy, pelvic lymphadenectomy, and peritoneal washing. Age, parity, menopausal status, weight, height, medical problems, history of previous laparotomy, surgical procedure, operative time, estimated amount of blood loss, preoperative hematocrit, postoperative hematocrit, operative complications, conversion to laparotomy, need for intraoperative or postoperative blood transfusion, intraoperative and postoperative complications, secondary surgery, tumor stage, grade, histology, number of recovered lymph nodes, and visual pain scores of the patients were recorded. RESULTS Postoperative complications were significantly higher in the laparotomy group. Hospital stay in the laparoscopy group was significantly lower than that in the laparotomy group. The visual pain scores were significantly higher in the laparotomy group on the first, second, and third postoperative days and on the day of discharge from the hospital. Resuming activity took a significantly longer time in the laparotomy group (34.70 days) than in the laparoscopic group (17.89 days). CONCLUSION With the availability of skilled endoscopic surgeons, most obese women with early stage endometrial cancer can be safely managed by performing laparoscopy with an excellent surgical outcome, shorter hospitalization, less postoperative pain, and faster resumption of full activity.
