Ultrasound finding of endometrial polyp and factors increasing risk of malignancy.

This article presents a comprehensive review of factors that increase the risk of malignancy in ultrasound findings of an endometrial polyp. We collected original studies, reviews, and meta-analyses that dealt with the topic of endometrial polyps and the risk of developing endometrial cancer. Each presumed risk factor was analysed individually. According to searched studies, abnormal uterine bleeding, old age, and body mass index are valid risk factors for developing endometrial cancer in endometrial polyps. Lynch syndrome patients are also in a high-risk group for endometrial cancer. On the other hand, the number of polyps, their size, diabetes mellitus, hypertension, and positive family history are factors with inconclusive results. There are either not enough data or different results among several studies.

Molecular testing of endometrial carcinoma in real-world clinical practice.

BACKGROUND: Molecular classification has brought significant changes in the management of endometrial cancer (EC). In this article, we aim to analyze our first experience with an implementation of molecular testing into daily clinical practice. MATERIALS AND METHODS: In all newly diagnosed EC, the status of mismatch repair (MMR) and p53 proteins has been evaluated immunohistochemically as a part of the routine histopathological examination since May 2021. In tumors that do not meet clinical criteria for a low risk and those with MMR deficiency or p53 mutation, the molecular genetic testing of the POLE gene is performed as well. Recommendations for adjuvant treatment or follow-up are subsequently made based on the risk of recurrence. Genetic counselling is proposed to all patients with MMR-deficient tumors or family history of cancer. RESULTS: A total of 85 patients with newly diagnosed EC between May 2021 and May 2022 were enrolled in the analysis. The median age was 66 years. The results of molecular testing were as follows: 22 (26%) MMR-deficient, 8 (9%) p53-mutated and none POLE-ultramutated of those 40 tumors with performed POLE sequencing. A total of 46 (51%) patient had a low risk, 2 (2%) intermediate, 14 (16%) high-intermediate and 20 (24%) patients had a high risk of recurrence. Advanced or metastatic diseases were diagnosed in 6 (7%) patients. The median time between surgery and multidisciplinary tumor board decision was 21 days (8-36). A total of 76 (90%) patients underwent the whole treatment plan according to the recurrence risk. At the time of analysis, the results of genetic testing were available in 18 patients and revealed 4 (22%) carriers of a pathogenic variant in any of the genes associated with Lynch syndrome. CONCLUSION: Molecular testing combining immunohistochemical analyses of MMR and p53 proteins in all newly diagnosed EC patients with sequencing analysis of POLE in those with non-low-risk disease is feasible and does not prolong the time needed for treatment decision.

The amount of preoperative endometrial tissue surface in relation to final endometrial cancer classification.

OBJECTIVE: To evaluate whether the amount of preoperative endometrial tissue surface is related to the degree of concordance with final low- and high-grade endometrial cancer (EC). In addition, to determine whether discordance is influenced by sampling method and impacts outcome. METHODS: A retrospective cohort study within the European Network for Individualized Treatment of Endometrial Cancer (ENITEC). Surface of preoperative endometrial tissue samples was digitally calculated using ImageJ. Tumor samples were classified into low-grade (grade 1-2 endometrioid EC (EEC)) and high-grade (grade 3 EEC + non-endometroid EC). RESULTS: The study cohort included 573 tumor samples. Overall concordance between pre- and postoperative diagnosis was 60.0%, and 88.8% when classified into low- and high-grade EC. Upgrading (preoperative low-grade, postoperative high-grade EC) was found in 7.8% and downgrading (preoperative high-grade, postoperative low-grade EC) in 26.7%. The median endometrial tissue surface was significantly lower in concordant diagnoses when compared to discordant diagnoses, respectively 18.7 mm2 and 23.5 mm2 (P = 0.022). Sampling method did not influence the concordance in tumor classification. Patients with preoperative high-grade and postoperative low-grade showed significant lower DSS compared to patients with concordant low-grade EC (P = 0.039). CONCLUSION: The amount of preoperative endometrial tissue surface was inversely related to the degree of concordance with final tumor low- and high-grade. Obtaining higher amount of preoperative endometrial tissue surface does not increase the concordance between pre- and postoperative low- and high-grade diagnosis in EC. Awareness of clinically relevant down- and upgrading is crucial to reduce subsequent over- or undertreatment with impact on outcome.

Total laparoscopic hysterectomy - clinical comparison of the method using two types of uterine manipulators.

AIM OF THE STUDY: Comparison of two types of uterine manipulators used in total laparoscopic hysterectomy (TLH) and clinical evaluation of the method in patients in a two-year group supplemented by subjective evaluation. DESIGN: Prospective observational study. SETTING: Department of Gynecology and Obstetrics, Masaryk University, Faculty of Medicine and University Hospital Brno. MATERIAL AND METHODS: A group of patients operated in the years 2018-2019 by the TLH method using one of two types of uterine manipulators - Karl Storz HOHL (group No. 1) vs. plastic ring of Koh's manipulator (group No. 2). We compared surgical time (min), blood loss (ml), perioperative complications, length of hospital stay (days), early and late complications. We were interested in the possible influence of BMI, uterine on these parameters. Subjective evaluation of the method by patients took place before the procedure and 12 weeks after the operation with a standardized questionnaire. RESULTS: A total of 134 patients were enrolled in the study (75 in group 1 vs. 59 in group 2). The monitored parameters: age, BMI, operative time, blood loss and length of hospitalization did not differ statistically significantly. When comparing the individual groups with different manipulators, the total number of complications (mild difficulties, serious complications) was without statistical significance (p = 0.58), but the spectrum of symptoms was different in both groups. More than a third of the patients in the group were obese. There were more serious complications than non-obese ones, the performance was longer, however, for a small number it was statistically insignificant (p = 0.11). In patients with uterine surgery, we recorded more adhesiolysis. We did not show that previous surgery on the uterus was associated with a higher incidence of complications (p = 0.6). We did not notice any statistically significant difference in the subjective evaluation (p = 0.3). CONCLUSION: TLH is the dominant method of uterine removal in our workplace. In a group of 134 women, we did not show a statistically significant difference in the monitored parameters. The HOHL manipulator has proved to be more user-friendly due to its technical parameters and better clarity of the operating field. Subjective evaluation of the method was positive in patients.

The role of hormonal therapy in patients with uterine carcinoma.

OBJECTIVE: The aim of the study was to describe the role of hormonal therapy in the treatment of malignant uterine tumors, indications, the effect of the treatment and to verify its safety in our study cohort. We also present an overview of recent studies on that topic. DESIGN: Unicentric retrospective observational study and review of recent literature. SETTING: Department of Obstetrics and Gynecology, Masaryk University, University Hospital Brno. METHODS: The results of recent relevant studies and reviews published in English until December 2017 were used for the review. The publications were searched using the PubMed server. All patients diagnosed in our oncogynecological center between 2010 and 2016 and who were treated hormonally - either in primary therapy or in relapse settings, were included in our study. We were interested in age, BMI, stage of disease, histological type and grade of tumor, occurrence of adverse effects, duration of survival, reasons for choosing hormonal therapy. Medroxyprogesterone-acetate or megestrol-acetate was used in the treatment. RESULTS: Between 2010 and 2016, 415 malignant tumors of the uterus were diagnosed in our oncology center. Recurrence of the disease occurred in 31 patients (8%), on average 16 months after primary treatment. Primary hormonal therapy was used in only 19 patients (5%), mostly because of contraindications of another treatment due to high age, comorbidities or obesity. Median age of patients was 83 years, mean BMI 41, median survival of patients who died was 8 months. Five patients (16%) were treated hormonally for the recurrence. Median survival from diagnosis of recurrence was 20 months. One patient (4%) experienced partial pulmonary embolism. CONCLUSION: Hormonal therapy plays an irreplaceable role in uterine cancer patients, especially in primary non-operable patients, in treatment of a relapse, or in a fertility-sparing procedure. This treatment option is safe, with minimal adverse effects.

[Postoperative administration of octreotide to reduce lymphorrhea, lymphocele, lymphedema and lymphatic ascites after lymphadenectomy in gynecological malignancies]. / Vliv pooperacního podání oktreotidu na redukci lymforey a následne vzniku lymfocyst, lymfedému a lymfatického ascitu po lymfadenektomii u gynekologických malignit.

INTRODUCTION: Octreotide is a synthetic analogue of natural somatostatin. Octreotide effect on lymphorrhea reduction in gynecological malignancies has only been assessed in case studies. DESIGN: Original work. SETTING: Gynecologic Oncology Center, Department of Obstetrics and Gynecology, Faculty of Medicine, Masaryk University and University Hospital Brno. METHODS: In 2014 there was a prospective, randomized, one-institution study. Patients underwent surgery including pelvic or pelvic and paraaortic lymphadenectomy for cervical, uterine and ovarian cancer. The informed consent was signed. Octreotide was evaluated in relation to diagnosis, surgery (laparoscopy versus laparotomy), pelvic and/or paraaortic lymphadenectomy, number of removed lymph nodes and their positivity, neoadjuvant chemotherapy, adjuvant chemotherapy, adjuvant radiotherapy, albumin, BMI, number of days with drains postoperatively, number of days in hospital, blood loss during surgery, time of surgery, total number of drains placed into abdominal cavity. In follow up period, within 1 year after surgery, we searched for lymphocele, lymph-edema of lower extremities and lymphatic ascites in relation to lymphorrhea. RESULTS: 44 patients (9 cervical, 19 endometrial and 16 ovarian cancer) were enrolled in two statistically comparable randomized groups. "Octreotide group", which paradoxically showed lymphorrhea of 4082 ml on average, (without 1992 ml, p = 0.001), needed drainage for more days (p = 0.001). The diagnosis had no influence on lymphorrhea in both groups (p = 0.966). The neoadjuvant chemotherapy was administered (p = 0.026), the more lymph nodes were removed (p = 0.018), the more days the drainage was in place (p < 0.001), the bigger the lymphorrhea; no relationship between lymphorrhea and age (p = 0.631), albumin level (p = 0.584), BMI ( p= 0.966) or number of positive nodes (p = 0.259), length of surgery (p = 0.206), blood loss (p = 0.494). Nor lymphedema (p = 0.404), nor lymphocele (p = 0.086), correlated with postoperative lymphorrhea. Lymphatic ascites was associated with lymphorrhea (p = 0.048). CONCLUSION: Octreotide did not reduce lymphorrhea and the incidence of lymphocele, lymphedema of lower extremities and lymphatic ascites within one year of follow-up period after surgery. According to our results, we do not recommend to administer the octreotide in oncogynecological patients after pelvic and/or paraaortic lymphadenectomy.

[Vascular anatomy and abnormalities of retroperitoneal pelvic and paraaortic area in relation to the radical oncogynecological surgery - individual experiences]. / Cévní anatomie aortopelvického retroperitonea a její abnormality v souvislosti s radikální onkogynekologickou operativou - vlastní zkusenosti.

OBJECTIVE: The overview of vascular anatomy and abnormalities of retroperitoneal pelvic and paraaortic area in relation to the radical oncogynecological surgery. DESIGN: Retrospective study. SETTING: Gynecologic Oncology Center, Department of Obstetrics and Gynecology, Faculty of Medicine, Masaryk University and University Hospital Brno. MATERIAL AND METHODS: The overview of visualized vascular anatomy of retroperitoneal pelvic, infrarenal suprapelvic and subhepatic area in relation to the radical oncogynecological surgery. Presentation of physiological vascular anatomy. Summary of the most common abnormalities and potential complications in terms of vascular injury. Basic management of these complications from the viewpoint of oncogynecologist. CONCLUSION: The perfect knowledge of vascular anatomy and its possible abnormalities has represented an absolute necessity for uncomplicated course and sufficient extent of radical surgery.

[Current FIGO staging classification for cancer of ovary, fallopian tube and peritoneum]. / Novinky ve FIGO stagingu karcinomu ovaria, tuby a peritonea.

INTRODUCTION: Pelvic high-grade serous carcinomas (HGSCs) include carcinoma of ovary, fallopian tube, and peritoneum. Five-year survival, irrespective of the stage, is between 35-40%. Most patients are diagnosed in advanced stages of the disease. The new revised and expanded dualistic model of ovarian carcinogenesis shows that type II tumors are composed for the most part of high-grade serous ovarian carcinoma, carcinosarcoma, undifferentiated carcinoma and can be further subdivided into morphologic and molecular subtypes. Many type II carcinomas develop from STIC predominantly in the distal portion of the fallopian tube and it is very likely the point of the origin of a significant subset of the pelvic high-grade serous carcinomas. OBJECTIVE: To provide an overview of major changes in our understanding of the origin of ovarian cancer, that led to the revision of FIGO (International Federation of Gynecology and Obstetrics) classification and its unification for the ovary, fallopian tube and peritoneum. We summarize the new classification, main changes compared to the former one and their clinical impact. METHODS: For this review, we have used the results of studies and review articles on the subject published in English up to October 2016. They were identified through a search of literature using PubMed, MEDLINE-Ovid, Scopus and Cochrane Library with the keywords ("serous tubal intraepithelial carcinoma" or "high-grade serous ovarian carcinoma" or "FIGO ovarian cancer staging 2014"). We retrieved and assessed potentially relevant studies, and checked the reference lists of all papers of interest to identify additional relevant publications. CONCLUSION: The origin of most cases of pelvic HGSC (carcinoma of ovary, the fallopian tube, and peritoneum) is expected in the fallopian tube epithelium. The main changes in the revised FIGO classification for extrauterine pelvic serous carcinomas were subdivision of stages IC, III and IV and elimination of the stage IIC, based on new knowledge and prognostic data. A prerequisite for the proper treatment of patients is to perform adequate surgical and pathological staging, including determining the grade of carcinoma. These factors, coupled with appropriately performed operation with zero postoperative residuum (R0), are the most important prognostic factors for patients with carcinoma of the ovary, fallopian tube, and peritoneum.

[Paraneoplastic neurological syndromes in gynecological malignancies]. / Paraneoplastické neurologické syndromy u gynekologických malignit.

OBJECTIVE: The demonstration of life-threatening paraneoplastic syndrome with dominant neurological symptomatology in germinal ovarian malignancy. DESIGN: Literature review with case report. SETTING: Department of Gynecology and Obstetrics, Faculty of Medicine Masaryk University and University Hospital Brno. METHODS: The review outlines the issue of paraneoplastic syndromes. It describes the etiopathogenesis, the range of clinical symptoms, the diagnostic and therapeutic possibilities, along with a relevant case study which focuses on the paraneoplastic neurological symptoms in malignant germinal ovarian tumor. CONCLUSION: Although paraneoplastic symptomatology is rather rare, it constitutes an important part of the clinical picture of malignant tumors. In a number of cases, the paraneoplastic neurological syndrome (PNNS) symptoms precede the actual tumor diagnosis. The awareness of this connection can thus be important in early diagnostics, which in turn can significantly affect a patients prognosis. Another important benefit of familiarity with the symptoms of neurological paraneoplasia is the fact that some PNNS are associated with specific tumors. Interdisciplinary cooperation is necessary in the case of PNNS for early tumor diagnostics. Treatment of the primary tumor is the key in diagnosed malignancies. With effective oncological treatment, adequate regression of paraneoplastic symptoms can be observed.

Screening of Psychological Distress 4.5 Years after Diagnosis in Breast Cancer Patients Compared to Healthy Population.

BACKGROUND: Survival rate of breast cancer patients has improved significantly in recent years. Cancer diagnosis represents a great psychological distress for patients which may not stem solely from the disease itself. Patients may experience higher distress even several years after treatment. PATIENTS AND METHODS: The study was carried out at the Department of Obstetrics and Gynecology and Department of Internal Medicine, Haematology and Oncology, Faculty Hospital Brno. Results of 85 patients at 4.5 years after diagnosis of breast cancer compared to 72 healthy controls are presented in this paper. The data were collected in the form of semi-structured interviews, from the patients medical records and by Symp-tom Check List-90. RESULTS: The overall rate of psychological distress (GSI) 4.5 years after breast cancer dia-gnosis does not differ significantly (p = 0.703) from the healthy population. Also, we did not find any statistically significant relationship between the observed factors and the level of psychological distress in breast cancer patients. CONCLUSION: Screening investigation showed no difference in the psychological distress in breast cancer patients 4.5 years following diagnosis, compared with the healthy population.

Change in Quality of Life Measured over Time in Czech Women with Breast Cancer.

BACKGROUND: This study examined the impact of breast cancer on quality of life (QOL) of Czech women by comparing the QOL of breast cancer patients with that of age-matched healthy controls. METHODS: The sample consisted of 74 breast cancer patients who filled in self-assessment questionnaires retrospectively before treatment and at the time of the study. In addition, 73 healthy controls completed the same battery of questionnaires. QOL was assessed using the Rand 36-Item Health Survey, the Life Satisfaction Questionnaire, and the Czech research version of Functional Assessment of Breast Cancer Therapy. The Wilcoxon paired test and Mann-Whitney U test were used for data analysis. RESULTS: A statistically significant decline in QOL in breast cancer patients was found for the following components: Physical Functioning (p = 0.021), Role Functioning-Physical (p < 0.001), Bodily Pain (p = 0.001), General Health (p = 0.031), Role Functioning-Emotional (p = 0.023), and Physical Well-being (p = 0.001). The only significant increase over time was observed in Social/Family Well-being (p = 0.024). For most of the components, patients showed a statistically significant lower QOL than that of healthy controls. A recent diagnosis, advanced disease stage, more comorbidities, a higher BMI, and other sociodemographic characteristics were associated with a higher incidence of a lower QOL over time. CONCLUSION: Perceived QOL decreased over time in breast cancer patients mainly in components such as physical and emotional functioning, bodily pain, and general health, with several risk factors strongly influencing this change. The QOL of patients was lower than that of the non-cancer population, indicating that subsequent care should be improved to minimize the adverse effects that breast cancer has on QOL.

Predicting Vitality Change in Older Breast Cancer Survivors after Primary Treatment--an Approach Based on Using Time-related Difference of Pro-inflammatory Marker C-reactive Protein.

BACKROUND: We aimed to determine prognosis of vitality change and functional status of breast cancer survivors after primary oncological treatment using time-related differences of elevated levels of highly sensitive proinflammatory C-reactive protein (CRP). PATIENTS AND METHODS: The test group consisted of 46 elderly breast cancer survivors (median age was 65 years) who completed Vitality Scale of Short Form 36 (SF-36) after completing treatment and another retrospectively at diagnosis. Data on tumor-related factors, treatment, and outcomes were obtained retrospectively from medical records, and linear regression analysis was performed. CRP was followed at diagnosis and one year after primary treatment. Within the scope of this study, clinically important difference in the Vitality Scale was set at five points of change. RESULTS: Results showed a statistically significant relationship between CRP change and vitality component of SF-36 change (rs = - 0.350, p = 0.023) in which a decrease in CRP inversely correlated with the quality of life component. The overall change was 1.078 of the vitality scale score (approximately 1 point) for each 1 unit decrease of CRP (1 mg/ L). Association of CRP levels (before and after treatment, its difference between these time points) with age, number of comorbidities and stage of the disease was analyzed and no statistically significant relationship was found in our study. CONCLUSION: Preliminary results suggested time-related differences in elevated CRP levels as a potentially suitable predictor for change in vitality status for long term, chronic condition for older breast cancer survivors. We suggest the interpretation schema including an understanding that CRP change of 5 mg/ L and more should be considered a potential risk factor for subsequent negative clinical outcomes.

Is human epididymis protein 4 an effective tool for the differential diagnosis of benign and malignant endometrial tumours?

PURPOSE OF INVESTIGATION: This study was designed to evaluate the use of human epididymis protein 4 (HE4) as a biomarker in the differential diagnosis of malignant and benign endometrial tumours. MATERIALS AND METHODS: The study, conducted between July 2009 and June 2014, included a total of 150 patients with endometrioid adenocarcinoma and a control group of 150 patients with benign endometrial lesions. The serum of all patients was analyzed with respect to HE4 and CA125 levels. The median and ranges of serum levels were determined in relation to histological results. The statistical analysis procedure employed in this study utilized logarithmic-transformed values of biomarkers and logistic regression. RESULTS: An analysis of two groups of patients with different histologies yielded a statistically significant difference (p-value < 0.05) only in the case of HE4, in which case a cut-off value of 48.5 pmol/l resulted in an achieved sensitivity of 87.8%, a specificity of 56.6%, and a negative predictive value of 81.1%. CONCLUSION: In combination with clinical and ultrasound findings, HE4 could help with the differentiation of prognostically varied patient groups as well as with the decision-making process associated with the development of individual treatment plans. However, the optimal cut-off for HE4 has not been established yet and further studies are needed.

Supernatant versus exosomal urinary microRNAs. Two fractions with different outcomes in gynaecological cancers.

MicroRNAs (miRNAs) are key regulatory molecules implicated in fundamental cell processes. Recent investigations have been focused to investigate their diagnostic potential also in various body fluids. Plasma and serum are widely used for these purposes. Urinary miRNAs, as the easily available type of sample, have been explored particularly in urological diseases recently. However, we have shown previously that differential expression of urinary cell-free miRNAs may be observed also in gynaecological cancers, such as ovarian and endometrial cancers. In the present article, we focus on the differences in particular urine cell-free miRNA abundance among different samples including particularly ovarian and endometrial cancers and rare gynaecological diagnoses involved in the study. Using raw abundance miRNA expression data, we confirmed significant up-regulation of miR-92a in ovarian cancer, and significant down-regulation of miR-106b in endometrial cancers. As miR-21 appeared up-regulated in the endometrial cancer similarly as in the verification process, where also miR-106b resulted in significant down-regulation in ovarian cancer, these miRNAs may be good candidates for further evaluation as novel diagnostics. To find out why supernatant but not exosomal urine miRNAs fraction resulted in significant results in regards to de-regulation of expression, we performed a comparison of the same urine samples isolated by these two manners. We show that diagnostic potential of cell-free urinary miRNAs may depend on the urine fraction used for the isolation. While particular urinary miRNAs may be enriched, other may reveal unchanged or diminished expression in the exosomal fraction in comparison with supernatant fraction, giving differences also between cancer and control samples. More research will be needed to further explore which kind of cell-free samples would give better results for diagnostic purposes in various diagnoses using urinary samples and investigating cell-free miRNAs expression. Meanwhile, different urine fractions should be explored for their miRNA expression to establish novel diagnostic urinary miRNA markers.

[Radical fertility preserving surgery of gynaecological malignancies - five-year-old file]. / Radikální fertilitu zachovávající operacní výkony u gynekologických malignit - petiletý soubor.

OBJECTIVE: Analysis of radical fertility preserving surgery, oncogynaecological treatment including their pregnancy effort. DESIGN: Prospective study. SETTING: Department of Obstetrics and Gynaecology, Masaryk University and Faculty Hospital Brno. METHODS: The group of 13 patients in age fifteen to thirty-six, who underwent radical fertility preserving surgery of oncogynecological tumors (cervix, ovarium), 9 patients with ovarian cancer and 4 patients with carcinoma of cervix. RESULTS: Histology showed seven times ovarial epithelial carcinoma, twice nonepithelial ovarial carcinoma, twice spinocelular cervical carcinoma, one adenosquamous and one lymfoepithelioma like carcinoma. We reported lymphocele as the most often postoperative complication by five patients with ovarial carcinoma, lymphoedema of lower limbs in one case and one of them complicated by bilateral hydronephrosis. After surgery procedures of cervical carcinoma, there was a stenosis of cervical canal with postoperative correction. In one case there was provided vaginal revision of cervix followed by embolisation of uterine arteries because of heavy bleeding in early postoperative period. After two years follow up, there are 12 patients in remission. There were four patients with fertlity plan, two with ovarial carcinoma, two with cervical carcinoma. The first group describes two pregnancies - one misscariage and one spontaneus labour in the date of delivery. There were 4 pregnancies in two patients wit cervical carcinoma. One patient has an intrapartal cesarean section because of scarring of the cervix after the operation. Next patients has two labours in due date, three labours in 34-37th week of pregnancy and one misscariage in 23 week of pregnancy. One patient has ovarial cancer during pregnancy, so the radical fertility preserving surgery was done after delivery. CONCLUSION: Methods and procedures of surgery with fertility preserving goals in our oncogynecological centre are in concordance with actual knowledge of medicine and respect oncological safety of patients with malignancies, who currently wish for fertility preserving treatment. Presented group of patients is relatively small, but results of oncological treatment and fertility plan demonstrate right-fulness of this treatment.

[The importance of HE4 in differential diagnosis of endometrial cancer]. / Význam HE4 v diferenciální diagnostice patologií endometria.

OBJECTIVE: The aim of the present study was to evaluate the use of human epididymis protein 4 (HE4) and cancer antigen 125 (CA 125) biomarkers in differential diagnosis of malignant and benign endometrial tumours in a population of Czech women. DESIGN: Prospective study. SETTING: Department of Gynaecology and Obstetrics, Faculty of Medicine at Masaryk University and Faculty Hospital in Brno. METHODS: Our prospective study includes 115 patients with endometrioid adenocarcinoma and 106 patients with benign endometrial tumours in the control group. They were diagnosed with endometrial biopsy in the period from 7/2010 to 6/2013. The patients with cancer underwent definitive surgical treatment to determine the stage of disease. The median and ranges of serum levels were determined in relation to the histological result (benign vs malignant disease). Statistical analysis operates with logarithm values of markers because their distribution is not normal and uses logistic regression. RESULTS: While analysing two groups of patients with different histology, there was demonstrated a statistically significant difference (p < 0.05), only in HE4, by cut-off 48,5 pmol/l there was achieved sensitivity of 87.8%, specificity of 56.6% and negative predictive value of 81.1%. COCLUSION: Diagnostic benefit of HE4 can be considered especially in patients with increased risk of endometrial cancer and in patients with serious internal co-morbidities. HE4 could help in combination with clinical and ultrasound finding in the differentiation of prognostically various groups of patients and in decision-making in relation to the individualization of the treatment plan. However, the optimal cut-off for HE4 has not been solved yet, and to do so, it will require more research with larger studies and their comparative analysis..

New perspectives in diagnosis of gynaecological cancers: Emerging role of circulating microRNAs as novel biomarkers.

Early diagnosis is a prerequisite of the more successful treatment of cancer. In gynaecological cancers, such as ovarian, endometrial and cervical cancers, the recent efforts are aimed at finding novel diagnostic biomarkers to help reduce the worldwide health burden associated with these cancers. In this review, we focus on the recent research progress in circulating, particularly cell-free microRNAs expression achieved in ovarian, endometrial and cervical cancers showing an opportunity to find novel diagnostic biomarkers for these malignant diseases. With the onset of microRNAs investigations showing their diagnostic potential in many diseases, their role in gynaecological cancers has been examined as well. However, similarly as in many other diseases, the vast majority of research on microRNAs expression has been dealing with tissue samples and cell lines. Recently, as the novel approaches focused on cell-free microRNAs expression have emerged, several studies identified their potential diagnostic and prognostic value in gynaecological cancers using blood, serum/plasma or urine samples. More research will be needed to establish circulating and extracellular microRNAs as the novel diagnostic markers for gynaecological malignancies. Inconsistency of results across the studies due to technical and biological variation, and a low number of this kind of investigations are the main potential pitfalls remaining to be resolved.

[Incidence and therapy of lymphoceles after pelvic and paraaortic lymph node dissection - our file]. / Incidence a terapie lymfocyst po provedené systematické pánevní a paraaortální lymfadenektomii - vlastní soubor.

OBJECTIVE: Analysis of lymphocele´s incidence and therapy among the patients, who underwent systematic pelvic and paraaortic lymphadenectomy during the years 2010-2012 in Oncogynecological centre of Department of Gynecology and Obstetrics in Brno. DESIGN: Retrospective study. SETTING: Department of Gynecology and Obstetrics, Masaryk University Hospital Brno. METHODS: We retrospectively evaluated the file of 111 patients, who underwent pelvic and/or paraaortic lymphadenectomy during the years 2010-2012 in our clinic. These patients were observed for the incidence of lymphoceles proved by ultrasonography. We focused on the incidence of symptomatic lymphoceles from all detected lymphoceles in the file of patients and we searched for relation between their presence and the type of systematic lymphadenectomy (pelvic or paraaortic) and the type of gynecological tumor and we report their management. RESULTS: During the years 2010-2012 we provided 111 lymphadenectomies consisting of: 78 pelvic and 33 pelvic and paraaortic lymphadenectomies in our clinic. These patients were rewied for retrospective study. We reported 37 cases of lymphoceles (33.3%) detected by vaginal or transabdominal ultrasonography. Among all patients with lymphoceles, we observed 24 asymptomatic patients and 13 patients with clinical features. There were 11.7% symptomatic lymphoceles from overall count. Only these symptomatic patients underwent therapy including simple punction or surgery management. Among all patients with lymphoceles, we reported the presence of lymfoceles by 19 patients with ovarian cancer (51.4%), 12 patients with cancer of cervix (32.4%), 4 patients with cancer of uterus (10.8%), one patient with cancer of salpinx and one patient with cancer of peritoneum (both 2.7%). We did not register statistically important dependence of lymphocele´s incidence on the type of lymphadenectomy (pelvic and/or paraaortic) - difference of 4.31%. CONCLUSION: Asymptomatic lymphoceles do not represent such a risk for patients after lymphadenectomy such as lymphoceles with clinical symptoms, which need to be followed by therapy. We proved incidence of lymphoceles 33.3%. There were 11.7% symptomatic lymphoceles among all patients after systematic lymph-adenectomy. In the future, it is necessary to standardize the condi-tions, used to indicate systematic lymphadenectomy to ensure safety of the oncological procedure and at the same time not to increase postoperative morbidity of patients. Going forward the topic of lymphocel´s prevention and detection of their valid risk and protective factors requires further prospective studies divided into single types of gynecological malignant tumors. KEYWORDS: pelvic and paraaortic lymphadenectomy, lymphoceles, incidence.

[Ovarian epithelial malignant tumors in adolescence]. / Ovariální epiteliální malignity v adolescentním veku.

OBJECTIVE: Ovarian epithelial malignant tumors in adolescence. DESIGN: Literature review with case reports. SETTING: Department of Gynaecology and Obstetrics, Faculty of Medicine at Masaryk´s University and Fakulty Hospital Brno. METHODS: Literature review on ovarian epithelial malignant tumors in adolescence, their epidemiology, diagnosis and therapy with illustrative case reports. CONCLUSION: The ovarian epithelial malignant tumors in the adolescence represent rare group of these diseases according to the data from the National Cancer Registry. However, it is a very sensitive area of oncogynecology, that requires highly personalized approach and the cooperation with patient´s family. The ovarian epithelial malignant tumors in the age group of 15-19 years show some differences from these diseases of adults and older women. The differences concern the extent of the disease at the time of the diagnosis, the histopathological characteristics of the tumors and the proportion surgical therapy and chemotherapy. The diagnostic algorithm requires the cooperation with the colleagues from pediatric gynecology and oncology. Due to the occurrence of localizated stages and good tumor differentiation prevails the monotherapy presented the surgical treatment, especially in the form of the radical fertility-preserving procedures. The care of the patients should be concentrated into the oncogynecological centres.
