Safety, feasibility, and short-term-outcome of anal endoscopic submucosal dissection for anal intraepithelial neoplasia: an option for focal lesions?

BACKGROUND: Anal intraepithelial neoplasia (AIN) appears in three different stages. AIN 1 and AIN 2 (p16 negative) are defined as low risk and unlikely to progress to invasive anal cancer. AIN 2 (p16 positive) and AIN 3 are of high risk and should be treated because progression rates to anal cancer are around 10% and treatment significantly reduces this risk. The correct treatment is still a matter of debate. Human papilloma virus (HPV) plays a role in the development of AIN. Our aim was to assess anal endoscopic dissection (aESD) as an intervention for AIN3. METHODS: We retrospectively evaluated patients who underwent aESD for AIN 3 between December 2017 and March 2023. The interventional technique itself (duration, complications, size of specimen) and patient outcomes (recurrence, progression to anal cancer, re-intervention) were analyzed. RESULTS: Fifteen patients with a median age of 52 years (23-78) underwent aESD for AIN 3. All tested specimens were positive for HPV. Median duration of intervention was 56.1 min, one delayed postinterventional bleeding occurred, and specimen size was 12.05 cm2. Median follow-up was 11.17 months. Three recurrences (20%) appeared: one was resected via biopsy and two were again treated with aESD. There was no progression to invasive anal cancer in the follow-up period. CONCLUSIONS: Anal endoscopic submucosal dissection seems to be a safe and feasible treatment for AIN. Recurrences are seldom and can be treated again with the same method. Nevertheless, indications for resection in comparison to radiofrequency ablation, pharmacological therapy, and watch-and-wait strategy are still unclear.

Coincidence of giant uterine myomatosis and detection of two advanced malignancies in 77-year-old female patient.

OBJECTIVE: Our aim is to emphasize the importance of patient participation in screening programs available in the Czech Republic and in preventive gynaecological examinations. As an example, we present a case report of a 77-year-old female patient with the accumulation of serious gynaecological diseases (extreme uterine myomatosis, breast cancer) and non-Hodgkin´s B-lymphoma. DESIGN: Case report. SETTING: Department of Obstetrics and Gynaecology, Faculty Hospital in Pilsen, Charles University Medical Faculty in Pilsen. CASE REPORT: Our case report of a 77-year-old patient is a rare case of the simultaneous detection of giant uterine myomatosis causing voluminous ventral hernia, invasive ductal breast cancer, and non-Hodgkin´s B-lymphoma. The patient was not gynecologically examined for last 20 years and did not undergo any screening examinations. In the postoperative period, the patient was diagnosed with invasive ductal breast cancer and follicular lymphoma. All the diseases were diagnosed in advanced stage. CONCLUSION: The occurrence of bulky fibroids is very rare in postmenopause. Long-term neglect of clinical symptoms and adverse health signals allows their gradual progression. Especially in older patients, other serious illnesses may complicate the situation.

[One-Step Nucleic Acid Amplification method - what is the future of sentinel lymph node management?] / Metoda One-Step Nucleic Acid Amplification - jaká je budoucnost zpracování sentinelových uzlin?

OBJECTIVE: The article summarizes current possibilities of usage of the One-Step Nucleic Acid Amplification method (OSNA) in the perioperative management of sentinel lymph nodes in oncologic surgery. The principle of this method is the detection of cytokeratin 19 (CK19) in the lymphatic tissue as a marker of the metastatic spread. DESIGN: Review article. SETTINGS: Department of Obstetrics and Gynaecology, University Hospital Pilsen, Faculty of Medicine in Pilsen, Charles University, Prague; Department of Biology, Faculty of Medicine in Pilsen, Charles University, Prague; Department of Immunochemistry, University Hospital Pilsen, Faculty of Medicine in Pilsen, Charles University, Prague; Sikl´s Department of Pathology, University Hospital Pilsen, Faculty of Medicine in Pilsen, Charles University, Prague. METHODS: The review of the literature published until the end of April 2017 available on the PubMed database was performed. The official abbreviation OSNA and the full name of the method One-Step Nucleic Acid Amplification was used for search in this database. CONCLUSION: The usage of the OSNA method with the detection of CK 19 in the sentinel lymph nodes as a marker of metastatic spread to the lymphatic tissue currently represents an acceptable form of perioperative sentinel lymph node management in patients with breast and colorectal cancer. Until now published data are pointing towards possible successful application of this method in sentinel lymph node management in patients with some other malignancies, such as thyroid carcinoma, gastric cancer, uterus cancer and head and neck cancer. More data is needed to establish this method also in those neoplasms.

[Carcinosarcoma of the endometrium with melanocytic differentiation, case report]. / Karcinosarkom endometria s melanomovou diferenciací, kazuistika.

OBJECTIVE: The case report presents a case of 60-year old woman with a rare malignant mixed Müllerian tumor with melanomatous differentiation diagnosed from a histology after cervical polyp ablation and curettage. DESIGN: Case report. SETTING: Department of gynecology and obstetrics, University Hospital in Pilsen. CONCLUSION: Carcinosarcoma, previously malignant mixed Müllerian tumor, is a very rare aggressive endometrial carcinoma with low incidence, which typically occurs among older women and commonly affects the uterine body and cervix. Clinically, the carcinosarcoma is impossible to be distinguished from endometrial carcinoma or uterine sarcoma and the definitive diagnosis can only be made based on histological examination.

Incidence of uterine sarcomas in West Bohemia, at the Department of Gynaecology and Obstetrics, University Hospital in Pilsen, Czech Republic.

OBJECTIVE AND SETTING: A retrospective review of women of the West Bohemian population was performed at the Department of Gynaecology and Obstetrics, University Hospital in Pilsen, Czech Republic from 1/2005 - 1/2017. METHODS: The following data was analysed: patients age, histological type, tumour size, FIGO stage, body mass index, previous irradiation, Tamoxifen usage, and other possible risk factors. A total number of 20 uterine sarcoma patients were detected in the period from 1/2005 to 1/2015, and these cases were followed until 1/2017. RESULTS: The histological types identified were: leiomyosarcoma in 12 cases, endometrial stromal sarcoma in 7 cases and one case of high-grade undifferentiated uterine sarcoma. This only patient diagnosed with high-grade undifferentiated uterine sarcoma showed distant metastases 12 months after the surgical treat-ment and died one month later. The whole group of uterine sarcoma patients regardless histological subtype reached two years in 50% of cases, with the median disease-free interval 18 months and the median follow up of 38 months. The diagnosis of sarcoma was already known in 25% of cases from dilatation and curettage histology. There were suspicious sonographic findings suggestive of sarcoma in 10% of cases. Multiparity was associated with 48.2% of endometrial stromal sarcoma cases. The leading clinical symptom was postmenopausal bleeding in 55% of patients. CONCLUSION: We confirmed uterine sarcomas to be rare malignancies, even in the Czech population with high uterine malignancy incidence. Uterine cold knife morcellation during the vaginal part of laparoscopically assisted vaginal hysterectomy didnt worsen the prognosis of our patients.

[Agressive small cell carcinoma of the ovary, hypercalcemic type, surgery and oncological treatment: case report]. / Agresivní malobunecný karcinom ovaria hyperkalcemického typu, chirurgická a onkologická lécba: kazuistika.

Small cell carcinoma of the ovary (SCCOHT) is a rare tumor typically affecting young women. It is a highly malignant tumor accompanied with poor prognosis, early relapse and low survival rates. The most significant prognostic factor is stage of the disease. Due to above mentioned factors there are no guidelines for therapy of this rare tumor. We present a case of 22-years-old patient initially treated with antibiotics under diagnosis of pelvic inflammatory disease. Due to persistent mass at left adnexa, she was indicated for diagnostic laparoscopy, converted to laparotomy and left adnexectomy with frozen section revealing unspecified malignant tumor of left ovary. A conservative operation was performed and, after diagnosis of SCCOHT was established, the patient was indicated for adjuvant chemotherapy.

[HE4 a biomarker of ovarian cancer]. / HE4 - biomarker ovariálního karcinomu.

OBJECTIVE: Verification of the importance of determination of HE4 and calculation of ROMA index for increasing the efficiency of diagnosis of ovarian cancer in a population of Czech women. DESIGN: Prospective study. SETTING: Department of Gynaecology and Obstetrics, Faculty Hospital in Pilsen. METHODS: In the period from 06/24/2010 to 12/01/2011 was at the Department of Gynaecology and Obstetrics, University Hospital Pilsen examined 552 patients with abnormalities in the pelvis. Patients were divided into two groups. There were 30 women with histologically confirmed malignant ovarian tumors. Another 522 women had benign findings. According to the levels of FSH were women in both groups divided into premenopausal and postmenopausal. At all women were measured CA 125, HE4 and FSH. HE4 and CA125 were determined using the chemiluminescent device Architect 1000 (Abbott, USA), FSH chemiluminescent method on the device DXI 800 (Beckman Coulter, USA). At all premenopausal women was calculated ROMA1 index and at all postmenopausal women ROMA2 index. SAS statistical software 9.2 were used for all statistical calculations. RESULTS: The highest diagnostic efficiency was achieved by a combination of HE4 and CA125 markers with the calculation ROMA2 index for postmenopausal women. In determining of menopausal status according to the values of FSH cut-off for menopause 40 IU/L and cut-off at 26.4% for ROMA2 reaches ROMA2 sensitivity of 92.3%, specificity of 88.5% and PV- of 99.3%. If we reduce the cut-off for laboratory diagnosis of menopause using FSH at 22 IU/L, and cut-off for ROMA2 was 26.3% reaches ROMA2 sensitivity of 95.2%, specificity of 87.8% and PV- of 99.5%. CONCLUSION: HE4 in combination with CA125 and current ROMA index calculation is a suitable methodology to improve the detection of ovarian cancer.

[Long-term follow-up of the health status of opiate abusers treated with methadone--pilot study]. / Pilotní studie k dlouhobému sledování zdravotního stavu abuzéru závislých na opiátech lécených metadonem.

BACKGROUND: Examination of the health status of patients abusing opiates can be substantiated by their high morbidity. The aim of the work was to describe the actual health status and the extent and seriousness of the affliction before the substitution therapy with opioid receptors agonist--methadone. METHODS AND RESULTS: The group of drug abusers consisted of 101 persons (average age was 28.5 years, within the range of 20 to 47 years, 77 men and 24 women). Among the pathological findings, values of the levels of hepatic enzymes ALT, AST (35 and 31%), GMT (9%), low haemoglobin levels (24%) and elevated values of IgM (38%) and CRP (25%) belonged to the most frequent ones. Because of the simultaneously positive tests for hepatitis (C and B, 70% and 61%), the alteration is fully obvious. Low testosterone levels in males (63%) indicate the dysfunction of the hypothalamus-hypophysis-gonadas axis. Increased values of thyroxin (14%), P (20%) and atherogenity index (19%) remain unexplained. Several other laboratory-biochemical parameters remained within the physiological range. Imaging methods revealed hepatomegaly in 28% and splenomegaly in 27%, echotexture indicating steatosis was found in 15% of studied persons. CONCLUSIONS: In chronic drug abusers before the onset of the substitution therapy, it is possible to expect frequent alterations, namely that of hepatic functions, positive test for hepatitis B and C, alteration of immunoglobulines level and testosterone deficits (in males).

Clinical findings with the oral contraceptive combination ethinylestradiol/dienogest in the Czech Republic.

The efficacy and safety of the low dose monophasic oral contraceptive (OC) combination containing 30 micrograms of ethinylestradiol (EE) and 2.0 mg of dienogest (DNG) (EE/DNG) was evaluated in a prospective, open-label, multicenter, uncontrolled, phase III trial. The trial was carried out in six hospitals by 36 investigators in the Czech Republic, and included 557 healthy women (aged 18-35 years), over 12 cycles, with a total of 6051 cycles. EE/DNG provided a reliable ovulation inhibition. The contraceptive efficacy study showed an adjusted Pearl index of 0.198 on the basis of three pregnancies occurring during 6051 cycles. EE/DNG provided good cycle control, reduced the incidence of intermenstrual bleedings, the intensity of menstrual bleeding and frequency of dysmenorrhea. Due to the antiandrogenic properties of the progestogen component DNG, EE/DNG improved androgen-related conditions, such as skin blemishes, hair greasiness and acne vulgaris. From 108 women with acne, 62 (57%) improved after the 6th cycle, and 16 (15%) were healed. Similar changes were found after cycle 12. Breast tenderness and headache were the most frequent of the common complaints due to treatment with EE/DNG. The frequency of all complaints decreased steadily over time. Only 7.7% of subjects discontinued due to adverse reactions. No thrombophlebitic events were noticed.

[Laboratory indicators in drug addicts and tertiary prevention of narcotic dependence]. / Nekteré laboratorní ukazatele u toxikomanu a terciární prevence závislosti na opiátech.

BACKGROUND: The authors report on some laboratory indicators in opiate abusers dependent for prolonged periods on opiates. The objective of the study is a proposal for an examination pattern in adepts during oral substitution therapy and emphasis on the necessity of systematic follow up of the health status. METHODS AND RESULTS: In 27 opiate abusers with a varying period of dependence on opiates the hematology laboratory tests was assessed, plasma levels of some minerals, renal and hepatic functions, some enzymes and metabolic indicators and vitamin D metabolites. For statistical evaluation Student's t-test was used and simultaneous testing. CONCLUSIONS: Long-term opiate abuse damages in 30 and 35% resp. liver functions. Therefore vitamin D deficiency develops. The authors recommend to follow up the health status of opiate abusers during oral substitution treatment (tertiary prevention).
