ABSTRACT
Human papillomavirus (HPV) is the most common sexually transmitted viral infection worldwide, which may result in the development in benign lesions or malignant tumors. The prevalence of HPV infection is twice as high in pregnancy as in non-pregnant women. Additionally, there is a risk of vertical transmission of HPV from mother to fetus during pregnancy or childbirth. Various studies have reported an increased risk of adverse pregnancy outcomes in HPV-positive women, including miscarriage, preterm birth, premature rupture of membranes, preeclampsia, fetal growth restriction, and fetal death. HPV vaccination is not currently recommended during pregnancy. On the other hand, there is no evidence linking HPV vaccination during pregnancy with adverse pregnancy outcomes and termination of pregnancy is not justified in this case.

INTRODUCTION: The main aim of organized national cervical cancer screening programs is to decrease incidence and mortality of this malignancy. A total of 770 cases of cervical cancer and 354 deaths from the disease were noticed in the Czech Republic in 2017 which means the incidence 14,5 new cases per 100 000 women. The Czech national cervical cancer screening program is based on cytology (Pap smear) testing in asymptomatic women once a year. OBJECTIVE: To provide an overview of new possibilities and potential tools in cervical cancer screening worldwide and in the Czech Republic. SETTING: Gynecologic Oncology Center, Department of Gynecology and Obstetrics, Hospital Na Bulovce and 1st Medical School of Charles University, Prague; Gynecologic Oncology Center, Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Medical School of Charles University, Prague. METHODS: For this review, we have used the results of studies, review articles, and guidelines of national cervical cancer screening programs published in English. We summarize the current knowledge of molecular genetic methods being applied in the screening of cervical carcinoma. CONCLUSION: The knowledge that persistent human papillomavirus (HPV) infection is the main cause of cervical cancer has resulted in the development of new possibilities of cervical cancer screening worldwide. HPV testing use for cervical cancer screening is now a reality with a quite lot of countries. Nevertheless, HPV testing is mainly used in the stratification of patients with unclear results of a cytological (PAP smear) result in the Czech Republic. While there is a wide and growing consensus that HPV molecular testing is the most accurate and cost-effective method of primary screening, there is a comparative lack of consensus regarding the optimal stratification of patients with proven HPV infections. Biomarkers, such a p16/Ki67 dual immunostaining, a methylation of viral DNA, a detection of E6/E7 mRNA, and others have been proposed for triage of HPV positive women. New possibilities and approaches in strategy of cervical cancer screening are discussed.

INTRODUCTION: The carcinoma of the cervix uteri is the fourth most common cancer in women worldwide and more than 85% of these cases occur in developing countries. Altogether 822 new cases were found in the Czech Republic during 2016 which means the incidence 15,3 new diseases/100,000 women. OBJECTIVE: To provide an overview of changes in FIGO (International Federation of Gynecology and Obstetrics) staging for carcinoma of the cervix uteri with an incorporation of possible imaging methods and/or pathological findings, and clinical assessment of tumor size and extent. SETTINGS: Gynecologic Oncology Center, Department of Gynecology and Obstetrics, Hospital Na Bulovce and 1st Medical School of Charles University, Prague; Gynecologic Oncology Center, Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Medical School of Charles University, Prague; Institute of Radiation Oncology, Hospital Na Bulovce, Prague. METHODS: For this review, we have used the results of studies, review articles, and guidelines of oncogynecologic organisations on the cervical cancer published in English. They were identified through a search of literature using PubMed, MEDLINE-Ovid, Scopus and Cochrane Library with the keywords. We summarize the new classification, main changes compared to the former one and their clinical impact. CONCLUSION: Lateral extension measurement is removed in the stage IA, the only criterion is the measured deepest invasion.

BACKGROUND: Here, we present a review of the revised FIGO (International Federation of Gynecology and Obstetrics) staging system for carcinoma of the cervix uteri, explaining the reasons for the changes and summarizing suitable diagnostic methods and treatment options for particular stages of disease according to current guidelines. AIM: The FIGO staging system has been revised as follows. Measurement of lateral extension has been removed from stage IA; the only criterion is a measurement for the deepest invasion of < 5.0 mm. Stage IB has been divided into three subgroups: IB1, tumors with a largest diameter measuring 5 mm and < 2 cm; IB2, tumors measuring 2-4 cm; IB3, tumors measuring 4 cm. Stage IIIC includes an assessment of retroperitoneal lymph nodes: IIIC1 if only pelvic lymph nodes are involved, and IIIC2 if para-aortic nodes are infiltrated. The revised staging system does not mandate the use of a specific imaging method or surgical assessment of the extent of the tumor. The method used to assign a stage should be recorded and reported. The European Society of Gynaecological Oncology, the European Society for Radiotherapy and Oncology, and the European Society of Pathology have developed clinically relevant and evidence-based guidelines to improve the quality of care for women with cervical cancer. These guidelines cover comprehensive staging, management, and follow-up for patients with cervical cancer. The guidelines are intended for use by gynaecologic oncologists, general gynaecologists, surgeons, radiation oncologists, pathologists, clinical oncologists, radiologists, general practitioners, palliative care experts, and other health professionals. CONCLUSION: We summarize the new FIGO classification system, including diagnostic methods and treatments for particular stages. We also discuss the main changes and their clinical impact.

OBJECTIVE: The aim of this study was to compare two cohorts of subjects who underwent termination of pregnancy up to 49 days of amenorrhoea by medical (pharmacological) termination (faUUT) and surgical instrumental termination of pregnancy (inUUT). DESIGN: Prospective clinical study. SETTING: Department of Gynecology and Obstetrics, Charles University in Prague, 1st Faculty of Medicine, Hospital Na Bulovce. METHODS: From August 2014 to July 2017, a total of 838 terminations of pregnancy up to 49 days of amenorrhoea were performed at our department. Altogether 474 of subjects underwent faUUT and inUUT was performed in 364 of women. We compared the anamnestic, sociodemographic, and health characteristics of women and we evaluated the efficacy, required medical interventions, medication use, the number and characteristics of complications in both groups. RESULTS: Women who underwent faUUT, were fewer with previous delivery (40.9% vs. 75.0%; p < 0.001), but they had more often previous artificial termination of pregnancy (27.8% vs. 19.5%; p = 0.003). The total number of outpatient visits was significant different between both cohorts, both in median (4 vs 1; p < 0.001) and arithmetic mean (3.8 vs. 1.2; p < 0.001). The usage of uterotonics was much higher in faUUT group (25.7% vs. 8.2%; p < 0.001). On the other side, the antibiotic use was similar in both groups (3.2% vs. 4.4%; p < 0.17). The surgical intervention (revisio cavi uteri instrumentalis, RCUI) required after termination of pregnancy was performed in 7.4% of faUUT cases and in 3.0% of inUUT group (p < 0.001). The failure of faUUT was found in 2 (0.4%) subjects. CONCLUSION: The complications and other followed parameters were various between both groups. Medical termination of pregnancy is a safe method with some potential non life-threatening complications.

OBJECTIVE: To summarize current knowledge of the relationship of genital and oral HPV infection in women. DESIGN: Review article. SETTING: Gynecologic Oncology Center, Department of Gynecology and Obstetrics, Hospital Na Bulovce and 1st Medical School of Charles University, Prague; Gynecologic Oncology Center, Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Medical School of Charles University, Prague; ENT Department, Hospital Na Bulovce, Prague. METHODS AND RESULTS: The infection of human papillomavirus (HPV) is strongly associated with the development of anogenital cancers and of a subset of head and neck squamous cell cancers, yet a quite little is known about the interrelationship between oral and cervicovaginal HPV infections. A key issue in oral HPV infection is whether it can be brought about a genital HPV infection, through sexual or other contact and by autoinoculation, or whether it can be considered a fully independent event. Pertinent to this issue is the frequency of oral HPV infection in women with a cervical HPV infection. Some studies show that females with genital HPV infection are at higher risk for oral infection and HPV genotype-concordance with genital infection are more prevalent than could be expected by chance. However, more data are needed to better understand the natural history of HPV infection at each anatomic site. CONCLUSION: The relationship of oral to cervicovaginal HPV infection remains unclear. Nevertheless, published data suggest that HPV infections at these two sites are not entirely independent, although genotype-specific concordance is low.

OBJECTIVE: To summarize knowledge about the mana-gement in women with proven actinomyces in uterine cervix and inserted intrauterine device (IUD). DESIGN: An overall review. RESULTS: Actinomycosis is an uncommon but important subacute or chronic infection caused by anaerobic or microaerophilic bacteria, mainly within the Actinomyces genus. Actinomycosis can affect various organs and tissues in the human body, often manifesting draining sinuses, abscess formation and fibrosis. The pelvic form in women is the most common in the developed countries. Long-duration treatment with antibiotics can be completely effective even in cases of heavy disease. Although pelvic actinomycosis is predominantly associated with the longstanding use of intrauterine device, the risk of future symptomatic infection is extremly low even in women with a cervical Pap smear positive for actinomyces-like organisms (ALO). Therefore the identification of actinomycetes by cytology after cervical Pap smears is not diagnostic nor predictive of any disease because the actinomycetes normally reside in the female genital tract. In the absence of symptoms, patients with ALO on a Pap test do not need antimicrobial treatment or IUD removal. Nevertheless, women choosing an IUD for contraception should know that there is very low risk of developing the infection in later years after insertion. CONCLUSION: The sources of literature conclude that removal of the intrauterine device in a patients with a positive ALO in the uterine cervix is not necessary and antibiotics treatment is not required. However, IUD must be changed at least every five years in order to limit the risk of the development of pelvic actinomycosis.

OBJECTIVE: In the Czech Republic (CR), it is possible, to carry out Medical Termination of Pregnancy (MToP) in the 1st trimester since June 2014, in case a woman submits a written request for it and in case the ultrasound examination confirms an intrauterine singleton prosperous pregnancy, between day 42 and 49 of gestation, crown-rump length (CRL) of the embryo 2-9 mm. The aim of the study is to analyze the management of MToP up until the 7th week of gestation in five centres in the CR. DESIGN: Multicenter cohort (prospective) study. SETTING: Department of Obstetrics and Gynecology, Palacky University Olomouc, Faculty of Medicine and Dentistry, University Hospital Olomouc; The Institute for the Care of Mother and Child, Charles University in Prague, Third faculty of Medicine; Department of Gynecology and Obstetrics, Charles University in Prague, First faculty of Medicine, General University Hospital in Prague; Department of Gynecology and Obstetrics, Charles University in Prague, First faculty of Medicine, Hospital Na Bulovce, Prague; Department of Gynecology and Obstetrics, Masaryk University, Faculty of Medicine, University Hospital Brno. METHODS: In 2014-2016, a total of 1820 pregnant women requested MToP. The diagnosis of an intrauterine singleton prosperous pregnancy was set by transvaginal ultrasound, CRL 2-9 mm. MToP was carried out by combination of mifepristone (600 mg orally) and misoprostol (400 mcg orally) within 48 hours. MToP follow up (exclusion of ongoing pregnancy) after 2-3 weeks was carried out by transvaginal ultrasound as well. RESULTS: In 11.0% of women (201/1820) who requested MToP, CRL > 9 mm, unprosperous, multiple or ectopic pregnancy was diagnosed. In the remaining 1619 women MToP was carried out, but in 221 cases (13.7%) at least one additional pre-first visit was needed before the diagnosis of intrauterine singleton prosperous pregnancy CRL 2-9 mm could be established, in 19 cases (1.2%) two pre-first visits and in 5 cases (0.3%) even three. Gestational age was 42-49 days (average 47.1, median 47), the women were 14-47 years of age (average 30.7, median 30). In 20.8% of women (336/1619) MToP follow up was missed and of the remaining 1283 women, ongoing pregnancy (MToP failure) was diagnosed in 1.6% (24/1283), incomplete abortion in 6.5% (83/1283) and complete abortion in 91.9% (1179/1283). A subsequent surgical intervention was carried out in 7.1 % of women (91/1283). CONCLUSION: A medical facility performing MToP in the 1st trimester should develop its own methodology in accordance with the legislation in force, Summaries of Product Characteristics, and recommendations of professional associations. The methodology should also include a method of evaluation of the result and management. The subsequent surgical intervention should only be performed in indicated cases. The main goal of MToP follow up is to exclude ongoing pregnancy (MToP failure), and the patient should be informed in detail about the risks involved and possibilities of their solution, it is necessary to obtain an informed consent.

Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide, which may result in the development of benign or malignant tumours. HPV infec-tions cause approximately 5% of all human cancers. Infection at all sites is strongly associated with sexual behaviour, but this association does not appear to explain substantial differences in the prevalence, incidence, persistence, and clearance of HPV infection in the anal, genital, and oral areas. Discussed are the similarities and differences among the natural histories of infection in different anatomical sites of the human body of both genders. Despite the huge advances already achieved, more research is needed to suggest effective prevention strategies (including the screening of high-risk groups and vaccination) for HPV infection and associated diseases.

OBJECTIVE: There are only a few gynaecological departments in the Czech Republic that use medical treatment of the ectopic pregnancy (EP) or persistent pregnancy of unknown location (PUL). We have started using this method in 2008 at our clinic. The aim of this study was to assess the success rate of conservative medical treatment with methotrexate (MTX) in the dose of 1 mg/kg intramuscularly in patients with ectopic pregnancy or persistent pregnancy of unknown location and to compare the results of clinical history, clinical finding and laboratory results in a group of successful and a group of unsuccessful treatment. TYPE OF STUDY: Retrospective analysis. SETTING: Charles University in Prague, 1st Medical Faculty and Hospital Bulovka, Department of Obstetrics and Gynaecology, Prague. METHODS: Patients diagnosed with EP or persistent PUL diagnosed at the outpatient of our clinic in 01/2008 - 08/2014 who were hemodynamically stable and fulfilled the indication for medical treatment were enrolled in the study. Treatment success was decrease of free subunit of ß-hCG (ß-hCG) < 5 IU/L independent of the number of methotrexate doses administered. RESULTS: Two hundred and eleven patients were diagnosed with EP or PUL, sixty-three were eligible for our study and fulfilled the criteria for methotrexate treatment, fifty six women were finally analysed. From this number forty eight (86%) had clinically and laboratory diagnosed EP and eight (14%) were diagnosed with persistent PUL. Forty one patients (73%) had a successfull treatment (Group I) with the ß-hCG level decrease <5 IU/L in a mean time of 27 days. When comparing the data of successful and unsuccessful treatment (Group II) we found a difference in the non-significant initial ß-hCG level. In Group I there was a median ß-hCG 538 IU/L (100-3852 IU/l), whereas in the unsuccessful Group II it was 1100 IU/L (300-3240 IU/l). Group I included more nuliparous women and more women with clinical histories of EP. Group II included more heavy smokers. The mean hematosalpinx diameter for group II, measured by transvaginal ultrasound, was larger. There were also more patients with endometriosis or deep infiltrating endometriosis in Group II, subsequently verified during laparoscopy, compared to Group I. There was no tubal rupture in these patients. CONCLUSION: The results of our study are comparable with foreign literature publications. We consider the pharmacological treatment of ectopic preganancy or persistent pregnancy of unknown location as effective and relatively safe for patients, with similar impact on a woman's fertility as laparoscopic salpingectomy.

TYPE OF STUDY: Summary review. SETTING: Department of Gynaecology and Obstetrics, 1st Faculty of Medicine, Charles University and Hospital Na Bulovce, Prague; Department of Physiology, Faculty of Science, Charles University, Prague; Department of Children and Adolescent Medicine, 1st Faculty of Medicine, Charles University in Prague and General Teaching Hospital, Prague. INTRODUCTION: Intrauterine growth restriction (IUGR) is one of the most common problems in obstetrics. Its incidence is ranging between 3-10%, according to the type of study population and chosen criteria. The cutoff value mainly used for defining the IUGR is weight below the 10th percentile for gestational age. The minority of authors defines the cutoff value under the 5th or 3rd percentile. Any pathological interference with normal vascular development of placenta may have a critical impact on foetal growth and development. Ischaemia is the most common cause of IUGR in normally well-supplied placenta. IUGR is then a consequence of insufficient extension, branching, and dilatation of capillary loops during the formation of terminal villi. METHODS: This paper is a review focused on up-to-date-known data concerning changes in placental angiogenesis and their impact on IUGR development. CONCLUSION: The aim of this review is to summarize the knowledge concerning the mechanisms of development of the vascular supply to the placenta under physiological conditions and in conditions that result in IUGR.

OBJECTIVE: To summarize new knowledge about the 2-dose HPV vaccine schedule in young adolescents. DESIGN: Review article. SETTING: Department of Gynaecology and Obstetrics, First Faculty of Medicine, Charles University and Hospital Na Bulovce in Prague; Oncogynaecological Center, First Faculty of Medicine, Charles University and General University Hospital in Prague. RESULTS: The goal of immunization programs in many countries is the prevention of cervical cancer using either the bivalent or the quadrivalent HPV vaccine. The vaccines, which were designed to prevent cervical cancer outcomes in adults, need to be administered before the onset of sexual activity. Since the HPV vaccines are among the most expensive of all the widely recommended vaccines, limited financial resources restrain the HPV vaccination in some countries around the word. Higher immunogenicity of both HPV vaccines in young adolescents, as well as potential cost savings, have prompted discussions about the efficacy of the 2-dose HPV vaccine schedule. Results of the immunobridging studies showed that two doses of the bivalent and the quadrivalent HPV vaccine in young girls induced geometric mean antibody titers that were non-inferior to geometric mean antibody titers elicited in older girls and women with three doses of the same vaccine. Non-inferiority for HPV-16, -18, -31 and -45 was obtained for the 2-dose of the bivalent HPV vaccine in girls 9-14 years old in the period of 48 months and for HPV-6, -11, -16 and -18 for the 2-dose of the quadrivalent HPV vaccine in girls 9-13 years old in the period of 36 months. CONCLUSION: These results indicate that the bivalent and the quadrivalent vaccine HPV vaccine applied in 2 doses has sufficient immunogenity in young girls.

UNLABELLED: The aim of our study was to determine the risk factors associated with anal HPV infection in HIV-negative women with high-grade cervical lesion. The study group included 172 "high-risk" women who underwent conization for high-grade cervical intraepithelial lesion or microinvasive cervical cancer (CIN 2+). The control group consisted of 100 "low-risk" women with non-neoplastic gynecologic diseases. All participants completed a questionnaire detailing medical history and sexual risk factors and were subjected to anal and cervical HPV genotyping. Concurrent cervical and anal HPV infections were detected in 42.4% (73/172) women of the study group, and in 8.0% (8/100) of women in the control group, respectively. The subgroup with concurrent HPV infections (n=73) dominated women with CIN 3 and microinvasive cancer and anal HPV 16 infections (n=53). Women with concurrent infections more frequently reported any type of sexual contact with the anus including non-penetrative anal sex (OR 2.62, p=0.008). Reporting >5 lifetime sexual partners (OR 2.43, p=0.041), smoking > 60 cigarettes per week (OR 2.33, p=0.048), and a history of penetrative anal intercourse (OR 3.87, p=0.002) were observed as the significant risk factors in women with multiple concurrent HPV infections. Our data support anal HPV testing and anal Pap smear screening in all women with severe cervical lesions caused by HPV 16 and a history of any sexual contact with the anus, heavy smoking and/or more than 5 lifetime sexual partners. KEYWORDS: anal cancer, cervical intraepithelial neoplasia, HPV, risk factor.
ABSTRACT
OBJECTIVE: To summarize new data which can help in decision on tailoring treatment of cervical precancerosis. DESIGN: Review article. SETTING: Department of Gynaecology and Obstetrics, First Faculty of Medicine, Charles University and Hospital Na Bulovce in Prague; Oncogynaecological Center, First Faculty of Medicine, Charles University and General University Hospital in Prague. RESULTS: Precancerous lesions of the cervix are represented by squamous cervical intraepithelial neoplasias (CIN) and glandular adenocarcinomas in situ (AIS). The usual treatment of cervical precancerosis is conisation. However, some complications, particularly subsequent adverse pregnancy outcomes, follow all surgical treat-ments of cervix. The treatment could be postponed in women who wish to conceive and who suffer from CIN with a low risk of transformation to invasive cancer. The presence of modifying factors can help to stratify CIN lesions according to their malignant potential. The determination of detected HPV genotypes may help in this decision, because the fate of CIN 2/3 depends on the genotype of associated HPV infection. Cervical lesions associated with HPV 16, 18 or 45 are at a much higher risk of rapid progression to invasive cancers than lesions associated with other HR HPV genotypes. Surgical treatment of CIN 2/3 in women with a desire for future child-bearing can be postponed in cases non-associated with HPV 16, 18 and 45, on a case by case basis. Attempts are made to improve evaluation of the lesions by using biological and molecular markers, especially p16INK4a staining. Younger age, ongoing pregnancy, favourable colposcopic findings, negative p16INK4a staining and immunocompetency are independent factors supporting the choice of conservative management. Adenocarcinoma in situ management substantially differs from the management of CIN. CONCLUSION: It is important both to assess all modifying factors correctly and to minimize any harm from unnecessary surgical treatment or overtreatment of cervical precancer lesions. KEYWORDS: cervical intraepithelial neoplasia, adenocarcinoma in situ, conisation, tailoring treatment, human papillomavirus genotype, p16.
ABSTRACT
BACKGROUND: There is a considerable number of studies on the efficacy HPV (human papillomavirus) vaccination against different cancers but relevant information is scattered in diverse journals. This paper is a review summarizing current knowledge of the potential of HPV vaccination against all HPV related cancers. AIM: HPV infection is probably the most frequent sexually transmitted disease. At least 13 HPV genotypes are classified as carcinogenic or probably carcinogenic in respect to cervical cancer. Almost 100% of cervical cancers are linked to HPV infection. HPV 16 and HPV 18 are the most frequently involved genotypes and account together for approximately 70% of cervical cancer in the world. Persistent high risk HPV infection is responsible for a significant proportion of vulvar, vaginal, anal and penile carcinomas. The virus has also been implicated in oncogenesis of head and neck cancers, including oropharyngeal cancers. HPV infection can play an important role in cancerogenesis of lung, esophagus, breast, and colon and rectum. On the contrary, published results indicate that HPV infection is not associated with prostate oncogenesis. Strong predominance of HPV 16 has been reported for all HPV associated cancer sites. Generally, it is estimated that approximately 5.2% of all cancers are associated with oncogenic HPV infection. Currently, there are two vaccines on the market; quadrivalent Silgard® (Gardasil®) and bivalent CervarixTM. Large trials for both vaccines have shown efficacy against HPV related infection and disease. Efficacy has been very high in HPV naive subjects to vaccine related types. While HPV vaccination is currently approved for the prevention of cervical cancer, it also has the potential in the prevention of all HPV associated malignancies. The Czech republic belongs to countries that cover HPV vaccination of girls at the age of 13-â14 years by general health insurance. Overall impact of this vaccination remains to be evaluated. The new issues of the role of HPV in oncogenesis, as well as the potential effect of HPV vaccination against HPV related nongenital cancers are discussed. CONCLUSION: Approximately 5.2% of all human cancers are associated with oncogenic human papillomavirus infection. HPV vaccination against the most risky HPV oncotypes may cause a significant reduction of these cancers mainly in the HPV naive population.

OBJECTIVE: Comparison of duration of surgery, blood loss, complications, lenght of post-operative hospitalisation and post-operative morbidity in a group of patient operated for the diagnosis FtM transsexualism. DESIGN: Retrospective clinical study. MATERIAL: In our set of patients were 163 FtM transsexuals with caryotype 46 XX and normal gynecological finding (81 virgins). They were operated on from 1998-2012 at Department of Obstetrics and Gynecology The First Faculty of Medicine Charles University in Prague and Hospital Na Bulovce after at least of 12 months of hormonal preparation. METHODS: We used following types of hysterectomy and bilateral adnexectomy: total abdominal hysterectomy from infraumbilical median laparotomy (AHL) or from suprapubic transverse incision - Pfannenstiel (AH), laparoscopically assisted vaginal hysterectomy (LAVH), total laparoscopic hysterectomy (TLH). In two patients TLH and colpectomy was performed in one setting. RESULTS: In the 23 AHL group the duration of the surgery was 54 minute, blood loss was 226 ml and the length of post-operative hospitalisation was 6.7 days. In the 22 individualy of AH group the duration of the surgery was 60 minute, blood loss was 240 ml and the length of post-operative hospitalisation was 6.1 days. In 4 patients of LAVH group the duration of the surgery was 73 minute, blood loss 200 ml and the length of post-operative hospitalisation was 5 days. In the TLH group (112 pts) the duration of the surgery was 91 minutes, blood loss was 121 ml and the length of post-operative hospitalisation was 4.4 days. In the 2 TLH with colpectomy group the duration of the surgery was 152 minute, blood loss was 250 ml and the length of post-operative hospitalisation was 5.5 days. In one case a peroperative lesion of urinary bladder occured and once a conversion TLH to AH for a strong vaginal bleeding was necessary. Among postoperative complication in one case subileus in AH group was diagnosed, once vaginal bleeding, once haematoma in the suture and one case of secondary healing. Postoperative complication after TLH included 4 times bleeding from vaginal suture, once haematoma in Douglas pouch, once seroma in the place of trocar insertion, once subileus. Once ureter was injured and treated by the ureteral stent insertion. Complication after AHL and LAVH were not recognised. CONCLUSION: Total laparoscopic hysterectomy is the method of choice in the group of FtM transsexuals. This technique could be used also in nuliparous women with long and narrow vagina. Compared with laparotomic approach lower blood loss and shorter hospital stay was proved. Earlier restitution of full activity is another advantage. Musculus rectus abdominis flap can be used for phallus construction. The only significant disadvantage is a longer duration of surgery.

BACKGROUND: Review of revised staging system for vulva, explaining the changes of staging and their impact on the prognosis of disease is presented. AIM: The main objectives of a reliable staging system include an assessment of prognosis, planning treatment, and the evaluation of their outcomes. A good staging system must meet three basic characteristics: validity, reliability and practicality. Since medical research and practice in the field of oncology have shown explosive growth, the staging of vulvar cancer and some other cancers did not give a good spread of prognostic groupings. Changes based on new findings were proposed in 2008 by the FIGO Committee on Gynecologic Oncology, approved, and published a year later the changes in the staging system for carcinoma of the vulva. Stage 0 was deleted, since it represents preinvasive lesion. Stage IA remained unchanged and stage I and II were combined. The number and morphology of the involved nodes were taken into account, and the bilaterality of positive nodes has been discounted. CONCLUSION: The purpose of a good staging system is to offer a classification of the extent of gynecological cancer, in order to provide a method of conveying ones clinical experience to others for the comparison of different treatment methods. As a result of the explosion of medical research in the field of oncology, the staging of some of the gynecological cancers became outdated and did not give a good spread of prognostic groupings. According to the revised staging for carcimona of the vulva, patients are divided to groups with similar prognosis. Therefore, exchange of relevant information between oncological centers is facilitated, thus disseminating knowledge and stimulating research in other parts of the world.

Currently developed selective progesterone receptor modulators (SPRMs) are steroid derived compounds with a bulky radical substitution at carbon 11. They interact with progesterone receptor and exert antagonistic or/and agonistic effects. Mifepristone was approved for pregnancy termination and ulipristal acetate as emergency contraception and pharmacological therapy of uterine fibroids. SPRMs inhibit endometrial proliferation and myoma growth, this suggests a therapeutical effect in cases of endometriosis and other estrogen-dependent diseases.
