Objectives: Uterine myomas (UM) are responsible for significant morbidity and have adverse effects on quality of life in women. Reactive oxygen species (ROS) and antioxidant enzymes (AOE), as well as sex steroids play important roles in the reproductive physiology processes. Thus, we aimed to investigate the role of oxidant-antioxidant status in UM by measuring the AOE activities and lipid peroxidation (LPO) levels. This is the first study assessing these parameters together in UM based on also menopausal status and evaluating possible correlations between AOE activities, LPO markers, tumor biomarkers, female reproductive system hormone levels, comprehensively., Study Design: The study group consisted of patients who have undergone surgical resection with confirmed pathology of uterine myoma (UM, n = 25) and divided into subgroups; premenopausal (UM pre ) and postmenopausal (UM post ). Erythrocyte copper-zinc superoxide dismutase (Cu,Zn-SOD), catalase (CAT), glutathione peroxidase (GPx1) activities were measured along with plasma malondialdehyde (MDA) and urinary 8-epi-prostaglandin F2α (8-epi-PGF2α) levels in patients with UM. The obtained data were compared to the data of healthy individuals (C, n = 25) and its subgroups; premenopausal (C pre ) and postmenopausal (C post )., Results: All AOE activities were higher (∼40% for Cu,Zn-SOD, p = 0.003; ∼55% for CAT, p = 0.001; ∼15% for GPx1, p = 0.169) and the LPO levels were lower (∼60% for MDA, p = 0.011 and ∼45% for 8-epi-PGF2α, p = 0.055) in patients with UM vs control. Approximately similar alterations were observed in UM pre vs C pre and in UM post vs C post. A significant negative correlation between erythrocyte Cu,Zn-SOD activity and plasma MDA levels (r = -0.431, p = 0.005) was reported., Conclusion: Decreased LPO levels might be the consequence of compensator high antioxidant enzyme activities against mild oxidative stress in the circulation of patients with UM. The marked negative correlation between erythrocyte Cu,Zn-SOD activity and plasma MDA levels also supported this finding., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Objectives: Previous studies have suggested an association between endometriosis and development of ovarian cancer. A study was performed to evaluate the cases of ovarian carcinoma associated with endometriosis., Study Design: The study includes patients with ovarian carcinoma associated with endometriosis diagnosed between 2000 and 2010 at Hacettepe University Hospital, Ankara, Turkey. A total of 1086 patients who underwent surgical staging for ovarian carcinoma were analyzed retrospectively for the presence of histologically documented endometriosis. The clinical and pathological characteristics of 45 ovarian carcinoma patients associated with endometriosis were evaluated including histologic subtype, stage and grade., Results: Ovarian carcinoma was found to be associated with endometriosis in 4.1% (45/1086) of the cases. Of them, 17 patients (37.8%) had clear cell, 15 (33.3%) had endometrioid, 6 (13.3%) had serous papillary, 4 (8.9%) had mucinous and the remaining 3 patients had an undifferentiated subtype of ovarian carcinoma. Twenty-three (51.1%) patients had stage I, 4 (8.9%) had stage II and 18 (40.0%) had stage III disease. The frequency of coexistence of endometriosis was 20.4% (17/83) for clear cell carcinoma and 9.3% (15/161) for endometrioid cell carcinoma., Conclusions: Only a small proportion of ovarian cancer cases were found to be associated with endometriosis. Endometriosis was most frequently associated with clear cell and endometrioid types of ovarian carcinoma. Ovarian carcinoma associated with endometriosis seems to represent a distinct disease entity with different histological subtypes, early presentation and a relatively favorable outcome., (Copyright © 2013 Elsevier Ireland Ltd.

A 24-year-old primigravid woman with adult type Gaucher's disease was admitted at 28 weeks of pregnancy. She was asthenic and the abdomen was markedly protuberant due to hepatosplenomegaly. A conservative approach with close monitorization of both mother and baby was planned. On the 39th week of pregnancy a healthy female baby of 3000 g was delivered via cesarean section. Apart from mild hematological complications, the pregnancy, the delivery and the puerperium were uneventful.

A retrospective analysis of 36 patients with metastatic nodes out of 209 consecutively managed patients with a clinically stage I endometrial cancer was carried out. Of the 1023 lymph nodes removed, 154 nodes were found to be metastatic. The mean number of the involved nodes was 4.27 (range: 1-29). Of the 154 positive nodes, 3 had nodal diameters < or = 3 mm (1.9%), 84 had diameters of 4-10 mm (54.6%), 60 had diameters of 11-20 mm (39.0%) and 7 had diameters more than 20 mm (4.5%). With increasing lymph node size, the frequency of tumoral involvement varies from 1.0% in nodes < or = 3 mm to 63.6% in nodes bigger than 20 mm. In terms of patients, nine of them were found to have a single metastatic node ranging from 6 mm to 10 mm in diameter. In the remaining 27 patients with multiple metastatic nodes, the biggest nodes encountered were 6-10 mm in 4 (14.8%), 11-20 mm in 17 (62.9%) and more than 20 mm in 6 (22.2%) patients. Since mere sampling of the lymphatic tissue directed particularly to the enlarged nodes may not show the true incidence of positive nodes, a complete lymphadenectomy is advocated in order to obviate an understaging problem.

This study includes 183 patients with clinical stage I endometrial carcinoma. All patients had standard surgical staging procedure including peritoneal cytology, total abdominal hysterectomy, bilateral pelvic and paraaortic lymphadenectomy. The factors analysed for recurrence were age, menopausal state, cell type, grade, mitotic activity, myometrial invasion, lymphovascular space invasion, cervical involvement, microscopic vaginal metastases, adnexal metastases, peritoneal cytology, concomitant endometrial hyperplasia and pelvic and paraaortic node metastases. The overall recurrence rate was 14.2% (26/183). Of the 26 patients with recurrence, 11 had local and 13 had distant metastases. In the remaining two patients (7.7%), both local and pelvic metastases were observed. Of the factors analysed, age, grade, mitotic activity, myometrial invasion, lymphovascular space invasion, microscopic vaginal metastases, adnexal involvement and pelvic and paraaortic nodal metastases were found to be significant predictors of recurrence. After multivariate analysis, advanced age (RR = 1.05), marked mitotic activity (RR = 3.11), pelvic and/or paraaortic nodal metastases (RR = 6.37) were chosen as the most important determinants of recurrence. In terms of surgical pathological stages, recurrence risk reaches up to 45.4% for stage IIIC disease. Using surgical pathological parameters, it is possible to predict recurrence but because of high rate of distant failures it still seems hard to improve survival of this group. Detection of a substantial risk of recurrence even in stage IA/B grade 1 group warrants adjuvant therapy in all patients after primary surgery.

A retrospective analysis of 136 patients with ovarian carcinoma subjected to appendectomy as a part of surgical procedure was carried out to assess the importance of appendectomy in patients with ovarian cancer. Of the 136 patients studied, 94 had epithelial and 38 had non-epithelial type of primary ovarian carcinoma. In the remaining 4 patients, the primary operation was performed with an intraoperative diagnosis of ovarian carcinoma but the final pathological examination revealed appendiceal carcinoma metastatic to ovaries. The overall appendiceal involvement in the study group with primary ovarian cancer was found to be 32.5% (43/132). This figure was 15.7% and 39.3% for non-epithelial and epithelial tumors, respectively. Involvement of the appendix ranged from 8.8% for patients with stage I disease to 46.0% for patients with stage III-IV disease. Four of the appendices found to be inflamed during the surgical explorations were later reported as acute appendicitis. The frequent occurrence of metastatic disease in the appendix in patients with ovarian cancer suggests routine appendectomy is appropriate for staging early cases and for contributing to maximal cytoreduction in advanced cases.

This study includes 39 patients with squamous carcinoma of the vulva subjected to radical surgery. Stage, tumor description, cell type, lesion localization, lesion size, depth of invasion, grade, lymphovascular space invasion, number of mitoses, degree of stromal inflammatory reaction, and tumors in surgical margins were analyzed for groin metastasis. Of the factors analyzed, stage (P = 0.018), grade (P = 0.007) and depth of invasion (P = 0.001) were found to be the most important predictors of node metastasis. While a combination of factors permitted to define a low-risk group with 0% node metastasis, it seems hard to identify preoperatively those patients with no risk of nodal metastasis.

This study includes 29 patients with synchronous primary malignancies of the female genital tract. These patients constituted 1.7% of all genital malignancies. The most frequently observed synchronous neoplasms were those of the ovary together with the endometrium (51.7%). Most patients had early-stage and low-grade disease. Stage I disease was observed in 68.1% of patients with ovarian cancer. Patients with synchronous ovarian and endometrial cancer had a 73.3% 5-year survival rate, suggesting a favorable prognosis.
