Reliable staging system should facilitate prognosis assessment, decision on treatments, and evaluation of their outcomes. A good staging system must meet three basic characteristics: validity, reliability, and practicality. The purpose of such system is to offer classification of the extent and progress of gynaecological cancer that will allow the comparison of different treatment methods and the choice of optimal treatment for individual patients. The previously developed staging of gynaecological cancers has become outdated because it has not considered results of current medical research that allow refinement of prognostic subgroupings. Changes based on new findings were proposed for staging of uterine malignancies by the FIGO (The International Federation of Gynecology and Obstetrics) Committee on Gynecologic Oncology and approved by the FIGO Executive Board in 2008, and were published in 2009. Stage 0 was deleted, since it did not represent any stage of invasive tumor. Four fundamental changes were made in the staging system of endometrium carcinoma. The revised staging system for endometrium carcinoma divides patients to groups with similar prognosis; carcinosarcoma is staged identically. The novel system will facilitate exchange of relevant information between diverse oncological centers and thereby promote knowledge dissemination and stimulate research around the globe. A different staging system was proposed for adenosarcomas, leiomyosarcomas and endometrial stromal sarcomas. It is based on features used for the sarcomas of other soft tissues. The purpose of the text is to review current knowledge in this area.
OBJECTIVE: Review of new staging systems for gynaecological cancers and their impact on prognosis and planning treatment. DESIGN: Review article. SETTING: Department of Gynaecology and Obstetrics, First Faculty of Medicine and University Hospital Na Bulovce, Charles University, Prague. Department of Radiotherapeutic Oncology, First Faculty of Medicine and University Hospital Na Bulovce, Charles University, Prague. Department of Pathology, University Hospital Na Bulovce, Prague. RESULTS: The main objectives of any good staging system--essential to an evidence-based approach to cancer--include planning treatment, providing an assessement of prognosis and the evaluation of the results of treatment. With this approach, the exchange of relevant information between oncological centers is facilitated, thus disseminating knowledge and stimulating research in other parts of the world. A good staging system must have three basic characteristics: validity, reliability, and practicality. The first staging system for gynaecological cancers appeared around the turn of the 20th century and was applied to carcinoma of the cervix uteri. Classifications for the other gynaecological malignancies were not created until the 1950s. Over the years, these staging classifications--with the exception of cervical cancer and gestational trophoblastic neoplasia--have shifted from a clinical to a surgical-pathological basis. Some changes, brought about through new findings, were approved by the FIGO in 2008 and published in 2009. The greatest changes were made in the new staging system for carcinoma of the vulva, while others were made in the new staging systems for carcinoma of the cervix and carcinoma of the endometrium. A new stanging system was also created for uterine sarcomas, based on the criteria used in other soft tissue sarcomas. CONCLUSION: As a result of the explosion of medical research in the field of oncology, the staging of some of the gynaecological cancers became outdated and did not give a good spread of prognostic groupings. Therefore, revised FIGO and TNM staging system has been structured to represent major prognostic factors in predicting patients' outcomes and lending order to the complex dynamic behavior of gynaecological cancers. The purpose of a good staging system is to offer a classification of the extent of gynaecological cancer, in order to provide a method of conveying one's clinical experience to others for the comparison of different treatment methods.

For treatment planning of cervical cancer it is necessary preoperatively to determine the presence and size of residual tumour after the biopsy, the tumour topography within the cervix and the parametrial and lymph node status. According to current data, ultrasound is comparably accurate with magnetic resonance imaging in view of tumour presence and local extent assessment. Ultrasound, if compared with the magnetic resonance imaging, does not have known contraindications and it is a broadly available diagnostic test. Currently no advanced imaging technique exists that can reliably detect infiltrated lymph nodes in the clinically early stage of the disease, as it often manifests as micrometastatic involvement in non-enlarged lymph nodes. The sensitivity of lymph node detection using ultrasound in the early stage is around 40%, but the specificity is high (96%). For daily practice, this means that a negative ultrasound finding should be always verified by surgical staging based on systematic lymphadenectomy, while positive ultrasound finding usually changes the treatment strategy.

RESULTS: Every staging system should have 3 basic characteristics: it must be valid, reliable, and practical.

A new stanging system was also created for uterina sarcomas, based on the criteria used in other soft tissue sarcomas. A clinical staging system for carcinoma of cervix continues because surgical staging cannot be employed worldwide (especially in third world countries). Stage 0 has been deleted from the staging of all tumours, since it is pre-invasive lesion and it is not an invasive tumour. In the revised staging system for carcinoma of the endometrium, four fundamental changes have occurred, which will be discussed. Carcinosarcoma is still staged identically to carcinoma of the endometrium. A completely new staging system was created for adenosarcomas, along with an almost identical staging system for leiomyosarcoma and endometrial stromal sarcoma. The staging system for carcinoma of ovary and Fallopian tube remains without changes. CONCLUSION: Since medical research and practice in the field of oncology have shown explosive growth, the staging of some of the gynaecological cancers did not give a good spread of prognostic groupings. Therefore, revised FIGO and TNM staging system has been structured to represent major prognostic factors in predicting patients' outcomes and lending order to the complex dynamic behavior of gynaecological cancers. The purpose of good staging system is to offer a classification of the extent of gynaecological cancer in order to provide a method of conveying one's clinical experience to others for the comparison of treatment methods.

BACKGROUND: The aim of our study was to determine validity of computed tomography in staging of non-small cell lung cancer. METHODS AND RESULTS: Sixty-two patients with NSCLC were operated at our department between March and September 2003. Lymph nodes with the shortest diameter over 10 mm on CT were considered abnormal. Primary tumor was correctly determined by CT scans in 77 % of cases, lymph nodes involvement in 63 %. Stage of NSCLC was correct in 53% of all patients. Negative predictive value for N1 and N2 was 80 %, resp. 88 %. CONCLUSIONS: Even with improvement in CT technology, validity of CT in staging of NSCLC remains low. We consider that mediastinoscopy can be avoided in the presence of normal mediastinal CT findings due to high negative predicative value of nodal improvement.

In 1997 and 1998 the authors implemented and evaluated endosonographic examinations of the rectum in 34 patients, incl. 22 on account of carcinoma and 12 for adenoma. Carcinomas classification T1 were recorded in 9%, T2 in 27.3%, T3 in 54.5% and T4 in 9%. Agreement with histopathological staging was recorded in 63.6%. In adenomas in 17% a suspect malignant appearance and spread into the muscularis propria was found and this was confirmed by histological examination. The results confirmed the contribution of routine endosonographic examinations to accurate staging and subsequent indication of different therapeutic modalities. From the surgical aspect it is important for assessment of the stage T4 and thus also primary inoperability. The examination is valuable also when it is impossible to visualize highly located tumours, as it rules out infiltration of adjacent organs.

BACKGROUND: Lymph node status is the most important prognostic and predictive factor in curatively resected colorectal cancer. According to TNM staging system, a minimum number of 12 regional lymph nodes is to be examined for the correct staging. In addition to the status of lymph nodes other important prognostic factors should be reported by the pathologist. METHODS: A retrospective study was performed to analyze how many of regional lymph nodes were examined in colorectal cancer specimens in two hospitals (Czech Republic) during the last few years. Availability of other prognostic factors important for the management of the disease after surgery was always investigated. RESULTS: In the hospital "A", the examination of lymph nodes were not sufficient in 43.8% of 121 cases analyzed, in the hospital "B", the number of examined lymph nodes was less than a minimum of 12 in all 162 cases. There were often no data available regarding to a histological examination of resection margins, grading and angioinvasion. CONCLUSION: Reporting of the standard and most important prognostic factors in colorectal cancer was not sufficient in two selected hospitals and it may not be much better in others. It might have a deteriorating influence on the outcomes despite of successfully performed primary surgery. Search for the new prognostic and predictive factors, that would help us to stratify the patients for the optimal tailored therapy is surely needed, but the standard staging parameters, as are the lymph node involvement, resection margins, grading and angioinvasion, must not be forgotten as occurred to be in many cases of our study.

OBJECTIVE: The aim of the presented study was to evaluate the accuracy of ultrasound staging of early stage endometrial cancer depending on grading, evaluation of ultrasound examination accuracy growing overtime with gained experience of examiners and comparison of subjective versus objective modalities of deep myometrial invasion assessment in the file of patients who were referred in The Oncogyneacologic Center, Department of Gyneacology and Obstetrics in České Budějovice. DESIGN: Retrospective study. SETTINGS: Department of Gyneacology and Obstetrics, Hospital České Budějovice a.s.Methods and the file: In this arcticle we retrospectively evaluate the file of 136 patients with early stage endometrial cancer. The patients underwent diagnostic and therapeutic procedures during the years 2012-2016 in our department. All these patients were able to be compared in different aproaches to deep myometrial invasion assessment using ultrasound examination. RESULTS: Comparing the used methods of deep myometrial invasion assessment with ultrasound examination of early stage endometrial cancer patients the examiner's subjective evaluation seems to be the best approach. After the first year of doing these assessments sensitivity performed 80%, specificity 79% and infiltration of cervix sensitivity 70% and specificity 99%. In case the patients were divided into groups according to the grading, low grade assessed worst sensitivity 64% (high grade l00%), but the best specificity 75% (high grade 56%). The evaluation of objective approaches of ultrasound assement with used cut offs performed the best sensitivity 81% tumour free minimal margin (specificity 67%). On the contrary the best specificity 90% performed the ratio AP (anteroposterior) diameter tumour/AP diameter uterine (senzitivity 54%). CONCLUSION: Generally in oncological therapy the most important things to put stress on the very accurate staging of oncological disease. In oncogyneacology ultrasound becomes more and more required examination. In our file we proved the significance of ultrasound examination in diagnostics and staging of endometrial cancer and we also proved that the accuracy level in early stage depends on the examiner´s experience. After one year practice our results reach the level of the results presented globally, no matter which of the methods - ultrasound MRI or frozen section - was used.

BACKGROUND: International Federation of Gynaecology and Obstetrics (Fédération Internationale de Gynécologie et d'Obstétrique - FIGO) introduced a new staging system for endometrial carcinoma - FIGO 2023 - in June 2023. OBJECTIVE: The new staging system differs significantly from previous versions. The new system represents a significant departure from the traditional staging systems for other gynaecological cancers, as the definition of individual stages includes not only the traditional anatomical extent of the tumour, but also the molecular profile of the tumour and other histopathological parameters - histological type of tumour, tumour grade and the presence of substantial lymphovascular invasion. The new system defines stages I and II in a completely different way and expands the definition of stages III and IV, allowing for different types of tumour spread outside the uterus. The introduction of molecular testing is the main change in the new staging system. When certain molecular markers are detected, stage I or II is completely changed. By including these non-anatomical parameters, the FIGO 2023 staging system improves the accuracy of a patient's prognosis at a specific stage with better options for individualized treatment, including the use of immunotherapy. Another goal was to synchronise staging as much as possible with the recommendations of three professional societies: the European Society of Gynaecological Oncology (ESGO), the European Society for Radiotherapy and Oncology (ESTRO) and the European Society of Pathology (ESP). The staging system for carcinosarcoma remains identical to the staging system for endometrial cancer. CONCLUSION: This article presents an overview of the new FIGO 2023 endometrial cancer staging system and discusses its advantages and disadvantages for clinical practice.
