Objective:To determine the long-term impact of laparoscopic cystectomy for endometriomas and benign cysts on ovarian reserve and selection of the most effective method of assessment. Methods:The present study was carried out between November 2013 and December 2016. Participants were assigned to laparoscopic cystectomy for diagnosed unilateral benign ovarian cysts and divided into groups: the endometrioma group (EG) (n=35) and the other benign ovarian tumor group (OG) (n=35). Before and at 3 and 12 months after the procedure, transvaginal ultrasonography was performed to assess antral follicle count (AFC) and ovarian volume (OvVol); laboratory tests were ordered for anti-Műllerian hormone (AMH) serum concentration assays. Pregnancy rates were counted in a 12-month follow-up. Statistica12 software was used for analysis. Results:The present study included 70 women aged 18-40 years. AMH serum concentration decreased significantly 3 months after laparoscopic cystectomy (4.89 ± 3.66 ng/mL to 3.45 ± 3.37 ng/mL; P<0.001). A greater decrease of AMH concentrations was observed in the EG (45.39% vs 14.87%; P=0.021). Twelve months of observation revealed a suppression in the drop of the AMH concentration, while AFC and OvVol remained unaffected. The likelihood of spontaneous pregnancy was three times higher in the OG (hazard ratio [HR] 3.57, 95% confidence interval [CI] 1.08-12.5). Conclusion:There was a significant decline in AMH levels in the EG 3 months after cystectomy. No further fall in AMH concentration was observed in the 12-month follow-up. The serum AMH concentration could be considered a valuable marker for ovarian reserve assessment after laparoscopic cystectomy. K E Y W O R D S

Leiomyomatosis peritonealis disseminata is a very rare, benign entity of unknown pathogenesis, characterized by the presence of multiple subperitoneal or peritoneal smooth muscle nodules throughout the peritoneal surface. Mostly the course is asymptomatic and it is found incidentally during laparotomy, laparoscopy or cesarean section. Non-specific symptoms such as abdominal pain, vaginal bleeding, abdominal mass or gastrointestinal signs are described. Rare cases of malignant transformation have been reported. We present a case of disseminated peritoneal leiomyomatosis with an unusual course and transformation to endometrial sarcoma in a 26-year-old previously healthy woman, where the appearance of peritoneal nodules was preceded by multiple incidents of fast fibroid growth and delivery of myomatous growth into the cervical canal.

Endometrial cancer is the most common malignancy within the female reproductive system (37.7%). The incidence increases with age. Frequently this type of cancer is diagnosed in peri- and post-menopausal women. 60-70% of cancers occur in women over 60 years of age, and less than 5% in women below 40 years of age.Angiogenesis is a process of formation of new microvessels from existing capillaries. There are four different mechanisms of new vessel growth: sprouting, intussusception, vessel elongation and incorporation of endothelial progenitor cells into new microvessels. Angiogenesis plays important roles in growth of endometrial cancers. This process is controlled by many angiogenic factors, for example vascular endothelial growth factor (VEGF). VEGF is the most powerful and most specific endothelial cell growth factor. It plays a crucial role in the initiation of physiological and pathological angiogenesis, lymphangiogenesis, and vasculogenesis. The VEGF family consists of VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, VEGF-F and PLGF (placental growth factor). The effects of VEGF are mediated through binding to the two specific and homologous receptors VEGFR-1 (FLT-1) and VEGFR-2 (KDR). Placental growth factor (PLGF) belongs to the VEGF family and it is also a very important growth factor. So far four isoforms of PLGF have been identified: PLGF-1 (PLGF131), PLGF-2 (PLGF152), PLGF-3 (PLGF203) and PLGF-4 (PLGF224).

Endometrial cancer is one of the most common cancers experienced by women throughout the world. It is also the most common malignancy within the female reproductive system, representing 37.7% of all disorders. The incidence increases with age, and is diagnosed most frequently in women between 45 and 65 years old. In the last few years, numerous studies have been performed to identify tumour biomarkers. Biomarkers include not only protein routinely used as tumour markers but also genes and chromosomes. The limiting factor in the use of markers in the diagnosis of endometrial cancer is their lack of specificity. However, specific markers for endometrial cancer are the subject of much research attention. Although moderately elevated levels of markers are present in a number of inflammatory or non-malignant diseases, significantly increased levels of markers indicate the development of cancer. Recently, research has been focused on the identification of molecular changes leading to different histological subtypes of endometrial cancer. In this paper the authors reviewed several currently investigated markers. Progress in these investigations is very important in the diagnostics and treatment of endometrial cancer. In particular, the identification of novel mutations and molecular profiles should enhance our ability to personalise adjuvant treatment with genome-guided targeted therapy.

Background. The widespread availability of ultrasonography means that transvaginal ultrasonography has become a routine procedure during gynecological examinations, even in asymptomatic patients. Nowadays the imaging technology offered by ultrasonography and tumor biomarkers give us an opportunity to implement transvaginal ultrasound-guided aspiration as a less radical treatment of simple ovarian cysts (SOC). Objectives. The aim of the study was a retrospective evaluation of the diagnostic and therapeutic efficacy of transvaginal ultrasound-guided aspiration of SOC in postmenopausal and premenopausal patients. Material and methods. A total of 84 women, divided into a premenopausal group (38/84) and a postmenopausal group (46/84), underwent transvaginal ultrasound-guided aspiration of small SOC (40-80 mm in diameter). Simple cysts were defined ultrasonographically according to the International Ovarian Tumor Analysis (IOTA) guidelines as cysts with negative risk of ovarian malignancy algorithm (ROMA) scores and CA125 levels. Simple ovarian cyst-related data was obtained from medical documentation (diagnostic tests, medical reproductive and surgical history, and clinical status during SOC aspiration). Follow-up data was collected by means of a telephone interview and medical database. The survey included questions focused on cyst recurrence during the 24-month period following the aspiration of SOC. Results. We had 100% compatibility with ultrasound diagnosis and cytological examination of aspirated fluid. The cumulative rate of cyst recurrence among 84 patients was 20.2% (17/84). There was a higher percentage of cyst recurrence in the premenopausal group: 27% (10/38) vs 15.2% (7/46) in the postmenopausal group, but the difference was not statistically significant (hazard ratio (HR) = 1.89, 95% confidence interval (95% CI) = 0.72-4.97; p = 0. 19). Recurrent cysts were treated with laparoscopic cystectomy, adnexectomy or a second aspiration in accordance with individual indications. Conclusions. Ultrasound-guided aspiration of small (<80 mm) adnexal SOC is a diagnostic and alternative therapeutic procedure, which allows cytological examination and may reduce the need for surgery, which is especially beneficial for women of reproductive age.
