Objectives: The role of angiogenesis in leiomyosarcomas still remains unclear. The aim of this study was to evaluate the NRP1 expression in the leiomyosarcoma tissues and to find the relations between its expression and the clinical features., Material and Methods: The study group consisted of 50 patients with diagnosis of the uterine leiomyosarcoma. Clinical and follow up data were collected. Using immunohistochemical methods the expression of NRP1 was detected., Results: The lack of NRP1 expression was found in 14 cases, positive (weak or moderate) expression was noted in 36 cases. The significantly higher expression of NRP1 was observed in more severe clinical stages in comparison to lower stages of the disease. The significantly shorter survival of patients with the positive expression of NRP1 in leiomyosarcoma was observed., Conclusions: The expression of NRP1 is associated with clinical advancement and worse prognosis in uterine LMS. Neuropilin 1 can be widely used as a postoperative survival predictor for the patients suffering from uterine LMS.

Objectives: The objective of the study was to retrospectively evaluate the density of vessels exhibiting positive glycoprotein CD34 expression in the uterine leiomyosarcoma tissues and their correlation with the age of patients at the time of tumor diagnosis., Material and Methods: The archival paraffin blocks with the cancer tissues collected from 50 patients suffering from uterine leiomyosarcoma were used together with their clinical and demographic data. The immunohistochemical peroxidase-de-pendent methods were used to detect microvessels with positive CD34 expression. The glycoprotein CD34 expression was evaluated as a density of microvessel showing the positive immunohistochemical reaction (MVDCD34)., Results: The negative, statistically significant correlation between the age of patients (at the moment diagnosis) and the MVDCD34+ (R = -0.289, p = 0.042) was found., Conclusions: The study's findings may suggest that the tissues of younger people constitute a permissive environment for pro-angiogenic factors.

Background: Neuropilin (NRP) may be used as a marker of lymphangiogenesis in malignant tumors. Significant correlations of the expression of NRP with tumor progression and overall survival prognosis were found in several cancer types. However; its potential role in epithelial ovarian cancer (EOC) has not been clarified., Aims: The aim of the work was to study a possible correlation of neuropilin-1 (NRP-1) expression with selected clinical and histological features of EOC., Material and Methods: The study included 53 women (aged 23 to 81, mean 56.6 +/- 14.4 yrs), 38 of which were postmenopausal (71.7%). Immunohistochemical staining with a specific anti-NRP-1 antibody was performed in representative tumor tissue samples of patients with EOC. Both, percentage of stained lymphatic cells and intensity of staining were assessed under 200x magnification. The results were correlated with the menopausal status, FIGO stage, histological type and histological grade of EOC., Results: Histological examination revealed that there were 27 cases of serous cancers (50%), 15 cases of mucinous cancer (28.3%) and 11 endometrioid cancers (20.7%). In 41.5% (n = 22) cases of EOC no NRP-1 staining was found, a weak (+) or strong (++) staining were found in 13 (24.5%) and 18 tumors, respectively There were no significant differences between neuropilin-1 expression and both menopausal status of women and histological type of EOC. Except for stage II, clinical EOC patients' FIGO stage was not correlated with the lack of expression (38.8% for stage I, 71.4% for stage II and 35.7% for stage III)., Conclusion: We believe that neuropilin-1 expression is probably not related to clinical and histological features of epithelial ovarian cancer:

Unlabelled: 24 patients with clomiphene citrate-resistant PCOS were enrolled in the study. We used low-dose step up protocol of recombinant FSH administration. Ovulation induction by rFSH injection was commenced on 3 day of cycle, at a dose of 50 IU for 7 days initially. The dose was continued at 50 IU, and ultrasonographic scans were performed daily until a dominant follicle had developed to a size of at least 18-20 mm, at which point 5,000 IU of hCG was administrated. If no response was noted after 7 days, the dose was increased by 50 IU for a further 7 days. Insulin and glucose serum levels were determined 7 times: in days 3, 5, 8 of a cycle and later when diameter of ovarian follicle was 10, 12, 16 mm and in the day of hCG injection. Estradiol serum level was determined in 8 day of cycle and when diameter of ovarian follicle was 10, 12, 16 mm and in the day of hCG injection. BMI and WHR was determined in the day of admission to hospital., Results: The correlation between mean insulin level in the examined cycle and BMI and as well as the correlation between mean insulin level and WHR were determined. Mean level of serum glucose increased as the level of estradiol raised. No influence of growth level on insulin level was detected.

The series of 14 hysteroscopic surgery procedures in case of septum uteri were analyzed. All women enrolled into the study were infertile. The malformations were diagnosed by hysterosalpingography and intravaginal ultrasound. The laparoscopic examination of intrauterine serosal surface and operative hysteroscopy were performed in the same time. The 8 mm diameter hysteroscopy with flexible needle was used. The uterine cavity solution was distended by sorbitol and mannitol. The patients left the hospital on the second postoperative day. There was one complication in this study: intravasation of distended fluid. After one month from surgery the pelvis was controlled by HSG. In 12 cases the uterine cavity was restored to a normal shape, in 2 cases the residual uterine septum of less than one centimeter was determined. We concluded that correcting the septum uteri by the small diameter hysteroscope (8 mm) with flexible needle is an effective and safety method for the uterine septum treatment.
