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.

Is the finding of endometrial hyperplasia or corporal polyp an mandatory indication for biopsy?

OBJECTIVE: The aim of our study was to analyze a group of patients referred for endometrial biopsy. To evaluate the ultrasound finding of hyperplasia/polyp, the symptomatology of patients related to the result of definitive histology, to determine the severity of individual variables in connection with the detection of precancerosis/cancer. Due to the complexity of information identify women who are suitable for conservative approach. DESIGN: Unicentric retrospective observational study. SETTING: Department of Obstetrics and Gynecology, Masaryk University, University Hospital Brno. METHODS: All patients over 50 years who underwent surgical endometrial biopsy at our department in the period of 2017-2018 (n = 754) were included. We were interested in reasons of indication, the age of patients at the time of the procedure and at the menopause, the presence of risk factors for development precancerosis/cancer (hypertension, diabetes mellitus, using of tamoxifen), number of deliveries and pregnancies, symptomatology, the description of ultrasound scans, the result of histology examination, peroperative and postoperative complications. RESULTS: Perimenopause - the median of endometrial thickness in both benign and malignant histology was 8 mm (p = 0.448), the median of the largest polyp dimension was 18 mm. All patients with precancerosis/malignancy were symptomatic with irregular/excessive bleeding, no carcinoma was found in polyp. Postmenopause - the median of endometrial thickness in benign histology was 7 mm versus 16 mm in precancerosis/malignancy (p < 0.001), the median of the largest polyp dimension was the same in both histologies (13 mm, p = 0.274). The risk of malignancy was more than threefold in bleeding versus asymptomatic patients with both hyperplasia and polyp (OR 3.39, 3.79). In asymptomatic patients the risk of cancer was similar for selected cut-offs (5, 8 and 12 mm), statistically significant only for 12 mm (OR 3.54), while in symptomatic patients the risk was high for all cut-offs, however with wide confidence intervals, statistically significant for cut-offs of 8 mm (minimum 3.58) and 12 mm (minimum 4.94). CONCLUSION: We have shown that symptomatology is a strong risk factor for the presence of precancerosis/malignancy in patients with endometrial hyperplasia or polyp. The thickness of the endometrium or polyp size in asymptomatic patients does not play a major role. Ultrasound alone does not have sufficient accuracy for detection or even screening of endometrial cancer. We recommend a conservative procedure, monitoring changes in the ultrasound scan and symptomatology of the patient over time.

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.

[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.

[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.
