Abstract We report a case of ovarian cancer with metastasis to both breasts and axillary lymph nodes and the vaginal cuff. A 41-year-old previously hysterectomized women presented with pelvic mass and malignant pleural effusion. During the courses of chemotherapy; bilateral breast nodules, and bilateral axillary lymphadenopathies and a nodule in the vaginal cuff were identified. The biopsy of both breasts, axillary lymph nodes and the nodule in the vaginal cuff revealed papillary serous cystadenocarcinoma. Immunohistochemical staining of breast specimens were positive for ovarian tumor marker CA-125.

OBJECTIVE To determine whether the neutrophil:lymphocyte ratio (NLR) and platelet:lymphocyte ratio (PLR) before complete surgical staging provide information on lymph node metastasis in vulvar squamous cell carcinoma (SCC). STUDY DESIGN All patients with vulvar SCC who underwent complete surgical staging at two institutions between 1 January 2005 and 31 December 2011 were identified retrospectively from patient databases. Receiver operating characteristic (ROC) curve analysis was used to evaluate cut-off, sensitivity, and specificity values for preoperative NLR and PLR to predict lymph node metastasis. RESULTS Data from 64 women with adequate information were analyzed. Lymph node involvement was detected in 19 (29.7%) patients. NLR and PLR were higher in the lymph node--positive group than in the--negative group (p < 0.001). The best cut-off values for predicting lymph node metastasis were 2.81 for the NLR, with 84.5% sensitivity and 89.5% specificity, and 139.5 for the PLR, with 68.9% sensitivity and 89.5% specificity. Forty of the 64 (62.5%) patients had NLRs ≤ 2.81 and 24 (37.5%) had NLRs >2.81. Lymph node involvement was more common in the NLR >2.81 group [60.7% vs. 5.6%; relative risk RR = 10.9, 95% confidence interval CI = 2.7-43.4; p < 0.001]. Mean tumor sizes were 4.2 ± 2.3 cm in the NLR >2.81 group and 2.1 ± 1.2 cm in the NLR ≤ 2.81 group (p = 0.001). The rate of lymph node involvement was higher in the PLR >139.5 group than in the PLR ≤ 139.5 group (54.8% vs. 6.1%; RR = 9.0, 95% CI = 2.2-35.9; p<0.001). CONCLUSION Preoperative NLR and PLR are directly associated with nodal involvement status of vulvar SCC. These markers are simple, readily obtained and calculated, and easy to integrate into the surgical work-up of patients with vulvar SCC, at no extra cost.

IntroductionLarge cell neuroendocrine carcinoma is a rare aggressive cervical neoplasm, considerably rarer than the well-recognized small cell neuroendocrine carcinoma of the cervix. Cervical large cell neuroendocrine carcinomas are distinctive cervical carcinomas that are frequently misdiagnosed and have an unfavorable outcome, similar to that of small cell carcinoma.Case reportWe report a 45-year-old woman with large cell neuroendocrine uterine cervical carcinoma.

Abstract Objectives: To determine the metabolic effects and efficacy of high-dose continuous megestrol acetate administration in the treatment of endometrial pathology. Material and methods: 27 women with histologically proven endometrial pathology (endometrial hyperplasia and irregularly proliferative endometrium) were treated with megestrol acetate orally 160 mg/d given once-a-day for 3 months. In 5 of 27 patients the dose of megestrol acetate was increased to 320 mg/d to alleviate irregular uterine bleeding. Serum lipid profiles and fasting and 2-h postprandial serum glucose levels were studied at baseline and one week after the therapy was completed. Results: HDL-cholesterol level significantly lowered from a mean of 50.4±11.1 mg/dL to 44.4±8.5 mg/dL after 3 months of megestrol acetate therapy (p<0.05). Serum total cholesterol level significantly lowered from a mean of 222.8±50.0 mg/dL to 192.7±36.5 mg/dL (p<0.05) and apolipoprotein A-I level from a median of 134 mg/dL to 116 mg/dL (p<0.05) after the therapy. Serum LDL-cholesterol, triglyceride, apolipoprotein B, fasting and 2-h postprandial glucose levels did not significantly change after the therapy (p>0.05). The median weight of patients was found to be 70 (53–110) kg before the therapy and 74 (56–111) kg after the therapy (p=0.001). Conclusions: The use of megestrol acetate, 160–320 mg/d, in the treatment of endometrial pathology is an effective method without marked harmful effects on serum lipid profiles or glucose levels but is associated with weight gain.

Background: Topotecan has been emerged as a new promising anticancer drug for patients with ovarian cancer. Methods: In this study, patients who were treated with topotecan were reviewed retrospectively. A total of 26 patients was included the study. All patients had received platinum-based regimens previously. Topotecan was administered a dose of 1.5 mg/m2 intravenously 30 min daily for 5 days and repeated every 21 days. Results: The response rates were 30% by CA-125 level and 29% in clinic evaluation. Median duration of response was 8 (3–15) months, median progression-free interval was 12 (4–30) months and median overall survival was 15 (4–36) months. Grade 3–4 neutropenia occurred in 58% of the patients (38% of the courses) and trombocytopenia in 29% of the patients (12% of the courses). Nonhematological toxicities were mild. There was no drug-related death. Conclusion: Topotecan is considered as a reasonable option for treatment of patients with platinum refractory recurrent ovarian cancer.

The objective of this study is to discuss the myomatous erythrocytosis syndrome in a patient with a giant subserous uterine myoma. She presented with plethora and an abdominal mass. After venesection of 4 units of blood, the preoperative haematocrit value of 53.3% and haemoglobin value of 17.5 g/dL had decreased to 48.6% and 16.8 g/dL levels, respectively. After the operative extraction of the giant subserous myoma with attached uterus weighing 14.2 kg, the haematocrit and the haemoglobin values had regressed to 40.3% and 14.3 g/dL levels, respectively. The findings indicated that the giant subserous myoma was the cause of the myomatous erythrocytosis syndrome in this patient.

AIM To predict the myometrial invasion with three-dimensional (3D) ultrasonography in a cohort of patients with endometrial carcinoma by a previously described technique. MATERIAL AND METHODS The moyometrial infiltration was evaluated by 3D ultrasonography before surgery in 54 patients with endometrial carcinoma. After scanning the whole uterus by ultrasonography, three perpendicular planes were identified to find the shortest myometrial tumor-free distance to serosa (TDS) by examining the lateral, anterior, posterior, and fundal parts of the myometrium. Myometrial infiltration was also estimated by the subjective impression of the examiner. The reference standards consist of myometrial infiltration and TDS which are measured by an experienced pathologist. RESULTS Forty-five patients (age range 45-86 years) were included for the final analysis. Myometrial invasion was ˂50% in 36 and ≥50% in 9 cases at histologic sections. The TDS which is measured with 3D ultrasonography was positively correlated with histologically measured TDS (r=0.474, p=0.001). The best cut-off value for ultrasonographically measured TDS was 9 mm with a sensitivity of 89%, specificity of 61%, positive predictive value of 36%, and negative predictive value of 96%. Subjective impression has a sensitivity of 100%, specificity of 88%, positive predictive value of 69%, and negative predictive value of 100%. Cervical involvement was correctly identified in all 6 cases by subjective impression. CONCLUSION This validation study confirms the 3D ultrasonography as a valuable tool for the evaluation of myometrial infiltration in patients with endometrial carcinoma.

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.

BACKGROUND Uterine sarcomas are rare, malignant, gynecological tumors and show diverse histopathological features. Therefore, there is no consensus on risk factors for poor outcome and optimal treatment. The aim of this retrospective analysis is to report the clinical outcome of patients with uterine sarcoma treated at a single center. MATERIALS AND METHODS The data was obtained regarding the patients demographic characteristics, pathological results, treatments given, survival, and complications of all uterine sarcoma patients treated in a single center between the years 2000 and 2012. The 80.month overall survival. (OS) was determined with respect to prognostic factors including age, stage of disease, histopathological type, and adjuvant treatment. RESULTS A total of 57 case records are retrieved for this retrospective analysis. The mean age of the patients is 62.5 ± 11.2 years. International Federation of Gynecology and Obstetrics (FIGO) stage distribution is stage I: 29; stage II: 13; stage III: 9; stage IV: 6. Fifty-seven patients underwent surgery, 33 received postoperative radiotherapy (PORT), and 32 received chemotherapy. Median follow-up period was 25 months (range 2-85 months). The 80-month OS for the entire group of patients was 36.7%. The significant prognostic factors for survival are age under 50 years, stage of disease, and adjuvant chemotherapy. CONCLUSION Although limited by small sample size and retrospective nature, age under 50 years, stage of disease, and adjuvant chemotherapy are significant prognostic factors for survival for uterine sarcomas.
