Quality of life after extended pelvic exenterations.

BACKGROUND: The aim of the study was to compare health-related quality of life (QoL) and oncological outcome between gynaecological cancer patients undergoing pelvic exenteration (PE) and extended pelvic exenteration (EPE). EPEs were defined as extensive procedures including, in addition to standard PE extent, the resection of internal, external, or common iliac vessels; pelvic side-wall muscles; large pelvic nerves (sciatic or femoral); and/or pelvic bones. METHODS: Data from 74 patients who underwent PE (42) or EPE (32) between 2004 and 2019 at a single tertiary gynae-oncology centre in Prague were analysed. QoL assessment was performed using EORTC QLQ-C30, EORTC CX-24, and QOLPEX questionnaires specifically developed for patients after (E)PE. RESULTS: No significant differences in survival were observed between the groups (P > 0.999), with median overall and disease-specific survival in the whole cohort of 45 and 49 months, respectively. Thirty-one survivors participated in the QoL surveys (20 PE, 11 EPE). No significant differences were observed in global health status (P = 0.951) or in any of the functional scales. The groups were not differing in therapy satisfaction (P = 0.502), and both expressed similar, high willingness to undergo treatment again if they were to decide again (P = 0.317). CONCLUSIONS: EPEs had post-treatment QoL and oncological outcome comparable to traditional PE. These procedures offer a potentially curative treatment option for patients with persistent or recurrent pelvic tumour invading into pelvic wall structures without further compromise of patients´ QoL.

Preoperative staging of ovarian cancer: comparison between ultrasound, CT and whole-body diffusion-weighted MRI (ISAAC study).

OBJECTIVES: To compare the performance of transvaginal and transabdominal ultrasound with that of the first-line staging method (contrast-enhanced computed tomography (CT)) and a novel technique, whole-body magnetic resonance imaging with diffusion-weighted sequence (WB-DWI/MRI), in the assessment of peritoneal involvement (carcinomatosis), lymph-node staging and prediction of non-resectability in patients with suspected ovarian cancer. METHODS: Between March 2016 and October 2017, all consecutive patients with suspicion of ovarian cancer and surgery planned at a gynecological oncology center underwent preoperative staging and prediction of non-resectability with ultrasound, CT and WB-DWI/MRI. The evaluation followed a single, predefined protocol, assessing peritoneal spread at 19 sites and lymph-node metastasis at eight sites. The prediction of non-resectability was based on abdominal markers. Findings were compared to the reference standard (surgical findings and outcome and histopathological evaluation). RESULTS: Sixty-seven patients with confirmed ovarian cancer were analyzed. Among them, 51 (76%) had advanced-stage and 16 (24%) had early-stage ovarian cancer. Diagnostic laparoscopy only was performed in 16% (11/67) of the cases and laparotomy in 84% (56/67), with no residual disease at the end of surgery in 68% (38/56), residual disease ≤ 1 cm in 16% (9/56) and residual disease > 1 cm in 16% (9/56). Ultrasound and WB-DWI/MRI performed better than did CT in the assessment of overall peritoneal carcinomatosis (area under the receiver-operating-characteristics curve (AUC), 0.87, 0.86 and 0.77, respectively). Ultrasound was not inferior to CT (P = 0.002). For assessment of retroperitoneal lymph-node staging (AUC, 0.72-0.76) and prediction of non-resectability in the abdomen (AUC, 0.74-0.80), all three methods performed similarly. In general, ultrasound had higher or identical specificity to WB-DWI/MRI and CT at each of the 19 peritoneal sites evaluated, but lower or equal sensitivity in the abdomen. Compared with WB-DWI/MRI and CT, transvaginal ultrasound had higher accuracy (94% vs 91% and 85%, respectively) and sensitivity (94% vs 91% and 89%, respectively) in the detection of carcinomatosis in the pelvis. Better accuracy and sensitivity of ultrasound (93% and 100%) than WB-DWI/MRI (83% and 75%) and CT (84% and 88%) in the evaluation of deep rectosigmoid wall infiltration, in particular, supports the potential role of ultrasound in planning rectosigmoid resection. In contrast, for the bowel serosal and mesenterial assessment, abdominal ultrasound had the lowest accuracy (70%, 78% and 79%, respectively) and sensitivity (42%, 65% and 65%, respectively). CONCLUSIONS: This is the first prospective study to document that, in experienced hands, ultrasound may be an alternative to WB-DWI/MRI and CT in ovarian cancer staging, including peritoneal and lymph-node evaluation and prediction of non-resectability based on abdominal markers of non-resectability. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Importance of addition of HPV DNA testing to the cytology based cervical cancer screening and triage of findings with p16/Ki67 immunocytochemistry staining in 35 and 45 years old women LIBUSE trial data analysis.

OBJECTIVE: The study evaluates results of 2-years follow-up of patients in ages 35-36 and 45-46, who are participating in the project LIBUSE, that deals with efficacy of HPV DNA and Pap smear co-testing and p16/Ki67 dual staining in the Czech national cervical screening. DESIGN: Prospective observational study. SETTING: Department of Obstetrics and Gynecology, General University Hospital and 1st Medical Faculty, Charles University, Prague. MATERIALS AND METHODS: Out of all women enrolled in the project LIBUSE only those who were at the beginning of the study 35-36 and 45-46 years old were sellected. Conventional Pap smear and HPV DNA test (Cobas 4800, Roche Diagnostics) had been collected at the baseline. Women were stratified according to their results in the three risk groups: 1. low-risk, 2. high-risk and 3. intermediate risk, who subsequently underwent p16/Ki67 dual staining. All high-risk patients and those with positive result of dual staing were refered to the expert colposcopy. The cases with biopsy proven precancers or cancers were considered as „positive findings“. RESULTS: Altogether 352 women meet the age requirements. In 26 (7.6%) women had been proven HPV DNA positivity and out of the them 9 cases were HPV 16/18 positive. Severe cytological abnormality was found only in one patient (0.3%), who was simultaneously HPV positive. Ten women (2.8%) were classified as high-risk and directly refered to colposcopy. Another 18 patients underwent p16/Ki67 dual staining and 4 positive cases were refered to colposcopy too. After one year further 9 patients were classified as intermediate risk and 6 more were identified after two years of follow-up. Within two years 9 more patient were refered to colposcopy. After the entire period of follow-up in 10 patients biopsy confirmed precancer lesions, none of them had invasive cancer. CONCLUSIONS: Addition of HPV DNA testing with selective HPV 16/18 genotyping to the cytology based screening significantly increases sensitivity and safety of our cervical screening program.

Prenatal care for woman after fertility-sparing surgery for cervical cancer.

AIM: To summarize the current knowledge about the care of pregnant women after fertility-preserving operations for cervical cancer. STUDY TYPE: Review article. SETTING: Department of Gynecology and Obstetrics, 1st Faculty of Medicine, Charles University and General University Hospital, Prague. METHODOLOGY: Search of published literature on a given topic using the PubMed database. RESULTS: Pregnant women after fertility-sparing surgery for cervical cancer can benefit from screening and treatment for asymptomatic bacteriuria, cervical incompetence screening, and progressive cervical shortening by transvaginal ultrasonography. Tests to determine the presence of biomarkers of preterm birth in cervicovaginal fluid improve the prediction of preterm birth. Vaginal progesterone supplementation should be the primary prevention of preterm birth in all women after trachelectomy. Women with a history of preterm birth or late abortion may benefit from cerclage. The preferred mode of delivery is the cesarean section after 37 weeks of gestation. CONCLUSION: Due to the lack of data, pregnancy management in women who have undergone fertility-sparing surgery for early cervical cancer is inconsistent. An increasing number of pregnancies after fertility-sparing surgery will likely prompt clinical research in this field.

What next in cervical cancer screening?

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.

[Glassy cell carcinoma of the uterine cervix: An aggressive type of cancer]. / Glassy cell carcinoma du col de l'utérus : une maladie tumorale agressive.

INTRODUCTION: Cervical cancer is the twelfth most frequent cancer in women in France. Glassy cell carcinoma is a rare histological entity, rapidly aggressive, associated with a poor prognosis. CASE REPORT: A 30-year-old woman was admitted in an internal medicine department for polyarthralgia with high grade fever, evolving for 3 weeks. There was an inflammatory syndrome. The 18-FDG-PET-scan showed inflammatory lymph nodes as well as disseminated osteolytic lesions, and a primitive pelvic tumor. A 3cm tumor of the cervix was found during the gynaecologic examination. Histological analysis elicited a high-index mitotic carcinoma, glassy cell carcinoma type. Despite chemotherapy, the outcome was poor, with early death occurring after three months of follow-up. CONCLUSION: The glassy cell carcinoma of the cervix should be considered as an aetiology of bone metastases in young female patients.

The changes in FIGO staging for carcinoma of the cervix uteri.

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.

Current FIGO Staging for Carcinoma of the Cervix Uteri and Treatment of Particular Stages.

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. This work was supported by the Charles University project UNCE 204065. The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers.

[The relationship between cervicovaginal and oral HPV infection]. / Vztah mezi cervikovaginální a orální HPV infekcí.

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.

SLN biopsy in cervical cancer patients with tumors larger than 2cm and 4cm.

OBJECTIVES: The aim of this study was to assess the detection rate, false-negative rate and sensitivity of SLN in LN staging in tumors over 2cm on a large cohort of patients. METHODS: Data from patients with stages pT1a - pT2 cervical cancer who underwent surgical treatment, including SLN biopsy followed by systematic pelvic lymphadenectomy, were retrospectively analyzed. A combined technique with blue dye and radiocolloid was modified in larger tumors to inject the tracer into the residual cervical stroma. RESULTS: The study included 350 patients with stages pT1a - pT2. Macrometastases, micrometastases, and isolated tumor cells were found in 10%, 8%, and 4% of cases. Bilateral detection rate was similar in subgroups with tumors<2cm, 2-3.9cm, and ≥4cm (79%, 83%, 76%) (P=0.460). There were only two cases with false-negative SLN ultrastaging for pelvic LN status among those with bilateral SLN detection. The false negative rate was very low in all three subgroups of different tumor sizes (0.9%, 0.9%, and 0.0%; P=0.999). Sensitivity reached 96% in the whole group and was high in all three groups (93%, 93%, 100%; P=0.510). CONCLUSIONS: If the tracer application technique is adjusted in larger tumors, SLN biopsy can be equally reliable in pelvic LN staging in tumors smaller and larger than 2cm. The bilateral detection rate and false negative rate did not differ in subgroups of patients with tumors<2cm, 2-3.9cm, and ≥4cm.

Vaccination against HPV and view of new possibilities.

OBJECTIVE: Overview of available information on current vaccination options against HPV and possibilities for further development. DESIGN: Review article. SETTINGS: Clinic of Gynecology and Obstetrics, University Hospital in Ostrava; Clinic of Gynecology and Obstetrics, General University Hospital in Prague. METHODS AND RESULTS: Three prophylactic vaccines have been developed against HPV infection and are all now avaliable in Czech Repulbic; nonavalent (Gardasil 9), quadrivalent vaccine (Silgard) and bivalent vaccine (Cervarix). Therapeutic vaccines, designed to induce regression of existing HPV-associated lesions, are in development and not yet clinically available. CONCLUSION: All three avaliable prophylactic vaccines show high efficacy in prevention of vaccine-specific HPV-type infection. The highest degree of protection is achieved in the population of HPV-naive women.

Pelvic floor reconstruction by modified rectus abdominis myoperitoneal (MRAM) flap after pelvic exenterations.

OBJECTIVE: To describe the technique and report experiences with pelvic floor reconstruction by modified rectus abdominis myoperitoneal (MRAM) flap after extensive pelvic procedures. METHODS: Surgical technique of MRAM harvest and transposition is carefully described. The patients in whom pelvic floor reconstruction with MRAM after either infralevator pelvic exenteration and/or extended lateral pelvic sidewall excision was carried out were enrolled into the study (MRAM group, n=16). Surgical data, post-operative morbidity, and disease status were retrospectively assessed. The results were compared with a historical cohort of patients, in whom an exenterative procedure without pelvic floor reconstruction was performed at the same institution (control group, n=24). RESULTS: Both groups were balanced in age, BMI, tumor types, and previous treatment. Substantially less patients from the MRAM group required reoperation within 60days of the surgery (25% vs. 50%) which was due to much lower rate of complications potentially related to empty pelvis syndrome (1 vs. 7 reoperations) (p=0.114). Late post-operative complication rate was substantially lower in the MRAM group (any grade: 79% vs. 44%; grade≥3: 37% vs. 6%) (p=0.041). The performance status 6months after the surgery was ≤1 in the majority of patients in MRAM (81%) while in only 38% of patients from the control group (p=0.027). There was one incisional hernia in MRAM group while three cases were reported in the controls. CONCLUSIONS: Pelvic floor reconstruction by MRAM in patients after pelvic exenterative procedures is associated with a substantial decrease in postoperative complications that are potentially related to empty pelvis syndrome.

[The prevalence, incidence, persistence and transmission ways of human papillomavirus infection (HPV)]. / Prevalence, incidence, perzistence a moznosti prenosu infekce lidským papilomavirem (HPV).

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.

[Current limits of cervical cancer prevention in the Czech republic]. / Soucasné limity prevence karcinomu delozního hrdla v Ceské republice.

OBJECTIVE: Cervical cancer represents disease with an unique possibilities of prevention. Despite this fact, it´s still detected excessive number of new cases and deaths annualy in our country. The aim of this work was to identify major limits of cervical cancer prevention in the Czech republic. DESIGN: Review article. SETTING: Department of Obstetrics and Gynecology, General University Hospital and 1st Medical Faculty, Charles University, Prague. MATERIALS AND METHODS: The main limit of primary and secondary prevention of cervical cancer is low participation rate of target population. Limits of screening include also inadequate age stratification of examination visits and usage of tests with a limited sensitivity. RESULTS: Combination of prophylactic vaccination in HPV-naive population with screening based on HPV DNA testing with selective genotyping are the strategies showing high efficacy, sensitivity and long-term negative predictive value. Essential requirement is as high as possible participation of young girls in national vaccination program and adult women in screening program. CONCLUSIONS: It cannot be expected further improvement of current results if primary and secondary prevention programs remain unchanged. Necessary steps comprise rising of public education about advantages of vaccination and legislative changes in screening program.

Accuracy of ultrasound in prediction of rectosigmoid infiltration in epithelial ovarian cancer.

OBJECTIVE: To examine prospectively the accuracy of ultrasound in predicting rectosigmoid tumor infiltration in patients with epithelial ovarian cancer. METHODS: Patients referred for a suspicious pelvic mass between 2012 and 2014 were examined by ultrasound following the standard protocol for assessment of tumor infiltration. Of the 245 patients examined, 191 had proven ovarian cancer and underwent primary surgery and were included in the analysis. Patients with apparently benign or inoperable disease were excluded. Rectosigmoid infiltration was evaluated by histopathology or according to perioperative findings. Clinical, pathological and laboratory parameters were analyzed as factors potentially affecting the sensitivity and specificity of sonography. RESULTS: The sensitivity of ultrasound in detecting rectosigmoid infiltration in patients with ovarian cancer was 86.3%, with specificity of 95.8%, positive predictive value of 92.6%, negative predictive value of 91.9% and overall accuracy of 92.1%. CONCLUSION: Ultrasound is a highly accurate method for detecting rectosigmoid tumor infiltration in ovarian cancer patients, and thus, can be used for planning adequate management, including patient consultation, surgical team planning, suitable operating time and postoperative care.

Ultrasound in preoperative assessment of pelvic and abdominal spread in patients with ovarian cancer: a prospective study.

OBJECTIVE: To analyze the accuracy of ultrasound in assessing pelvic and intra-abdominal spread in patients with ovarian cancer. METHODS: This prospective study enrolled all consecutive patients referred to a single gynecological oncology center for suspected ovarian cancer. We analyzed only data from patients with histologically confirmed primary ovarian cancer who were evaluated following predefined preoperative ultrasound, intraoperative and pathology protocols. We evaluated the agreement of depth of infiltration of the rectosigmoid wall, tumor spread in different peritoneal compartments and presence of metastatic retroperitoneal and inguinal lymph nodes, as determined at ultrasound, with intraoperative and histopathological findings. RESULTS: In total, 578 patients were enrolled between March 2008 and January 2013, of whom 394 met the study inclusion criteria and were analyzed; 74% of these suffered from advanced-stage cancer. Our results showed excellent agreement between ultrasound and histology in assessment of rectosigmoid wall infiltration (kappa value, 0.812; area under the receiver-operating characteristics curve, 0.898). The overall accuracy in evaluating different peritoneal compartments, retroperitoneal and inguinal lymph nodes and depth of rectosigmoid wall infiltration was 85.3%, 84.8%, 99.7% and 91.1%, respectively. Ultrasound showed high sensitivity only in the assessment of rectosigmoid wall infiltration (83.1%), peritoneal spread into the pelvis (81.4%) and omentum (67.3%), and inguinal metastatic lymph nodes (100%). The specificity of ultrasound in detection of all evaluated parameters was > 90%. CONCLUSION: This is the largest imaging study to date on ovarian cancer staging. Ultrasound can be used as the method of choice to plan rectosigmoid wall resection and dissection of infiltrated inguinal lymph nodes. In assessing different peritoneal and retroperitoneal compartments, ultrasound was accurate and highly specific. However, similar to other modern imaging techniques, it had relatively low sensitivity, further supporting the role of comprehensive surgical staging. Copyright © 2016 ISUOG.

[Current knowledge about HPV infection]. / Aktuální poznatky o HPV infekci.

OBJECTIVE: Overview of current data on HPV infection. DESIGN: Review article. SETTING: Clinic of Gynecology and Obstetrics, University Hospital in Ostrava, Clinic of Obstetrics and Gynecology, University Hospital in Hradec Králové, Clinic of Gynecology and Obstetrics, General University Hospital in Prague. METHODS AND RESULTS: Human papillomavirus is a sexually transmitted pathogen that causes anogenital disorders. Persistent viral infection with high-risk human papillomavirus (HPV) genotypes causes virtually all cancers of the cervix, 60% of vulvar cancers, 70% of vaginal cancers and 93% of anal cancers. CONCLUSION: The discovery of oncogenic potential of HPV and knowledge about etiopathogenesis of HPV infection has enabled great advances in primary and secondary prevention of precancerous lesions and malignant diseases.

[Technique of pelvic and paraaortic lymphadenectomy]. / Technika pánevní a paraaortální lymfadenektomie.

OBJECTIVE: Overview of classification, anatomical conditions, methods and complications of pelvic and paraaortic lymph-node dissection. DESIGN: Review article. SETTING: Department of Obstetrics and Gynecology, General Faculty Hospital and 1st Medical Faculty, Charles University, Prague. MATERIALS AND METHODS: Lymphadenectomy is classified according to its extent into sentinel lymph-node biopsy, debulking, sampling and systematic procedure and according to approach into extraperitoneal or transperitoneal procedure. The most complex variant is systematic pelvic and paraaortic lymph-node dissection, which requires removal of fatty-lymphatic tissue from anatomically strictly defined areas. Procedure can be performed from laparotomy, laparoscopically or robotically. RESULTS: The main objective criterium of systematic procedure is the number of harvested nodes. The most common complications comprise bleeding and lymphocele formation. CONCLUSIONS: Pelvic and paraaortic lymphadenectomy represent basic component of surgical management in majority of gynecological cancers. The knowledge of extent, different techniques and ability to solve complications represents essential skill in gynecological oncology.

[Contribution of sentinel lymph-node biopsy to treatment of locally advanced stages of cervical cancers]. / Prínos biopsie sentinelových uzlin pro lécbu lokálne pokrocilých stadií karcinomu delozního hrdla.

OBJECTIVE: Usage of sentinel lymph-node (SLN) concept in locally advanced cervical cancers might help to individualise management. According to SLN status could be patients refered to neoadjuvant chemotherapy (NAC) with subsequent surgery or to primary chemoradiation. The aim of our study was to evaluate sensitivity of SLN detection in locally advanced cervical cancers and to assess the impact of NAC on frequency of their metastatic involvement. DESIGN: Retrospective clinical study. SETTING: Department of Obstetrics and Gynecology, General Faculty Hospital and 1st Medical Faculty, Charles University, Prague. MATERIALS AND METHODS: Included were patients with cervical cancer stages FIGO IB1 (> 3 cm), IB2, IIA2 and selected cases of stages IIB with incipient parametrial involvement. Patients were distributed into two different protocols - patients in group NAC-SLN were refered to radical hysterectomy with SLN biopsy after 3 cycles of NAC, other patients (group SLN) underwent SLN biopsy and NAC was administered only in SLN-negative cases. RESULTS: Altogether 101 patients were included (group SLN = 62, group NAC-SLN = 39). Detection of SLN in whole cohort reached 90.1% per patient and 68.3% bilaterally. No differences were found between SLN group and NAC-SLN group in frequency of per patient SLN detection (90.3% vs 89.7%) and bilateral detection (69.4% vs 66.7%). Prevalence of macrometastases, micrometastases and ITC in the SLN group was 37.1% (23/62), 11.3% (7/62) and 8.1% (5/62), respectively. In the NAC-SLN group macrometastases in SLN were detected in 17.9% (7/39) patients, in 1 patient was detected micrometastis in SLN and no patient had ITC. Difference in frequency of metastases in SLN was significant (p = 0,013). No patient had progressed during NAC, complete response was seen in 15.1% (11/73) patients and reduction of tumour volume > 30% in 84.9% (62/73) patients. CONCLUSIONS: Detection of SLN in locally advanced cervical cancers reached comparable results to early stages. NAC did not influence frequency of SLN detection, but it significantly decreased prevalence of metastatic SLN involvement.
