Fluorine 18 FDG PET/MRI, in which MRI and PET data are acquired simultaneously in a single scanner, demonstrates promise to be an important tool in FIGO cervical cancer staging (42). Would you like email updates of new search results? Figure 4c: Images show uterine cervical cancer lymphadenopathy at fluorodeoxyglucose PET/CT versus CT. (a) Coronal maximum intensity projection PET image in a patient clinically staged as IB shows hypermetabolic foci in pelvis (arrowheads) and abdomen (arrows), which at fusion PET/CT (not shown) correspond to retroperitoneal lymphadenopathy. Aside from staging, if radiation therapy is anticipated, then pelvic MRI is the preferred examination for treatment planning because it best defines the geometry of tumor growth in the central pelvis (54). La détermination précise du stade d’un cancer est l’un des facteurs déterminant pour le choix du type de traitement. (b) Sagittal MRI after gadolinium-based contrast agent administartion shows that tumor (arrows) extends into uterine corpus and measures 4.8 cm, corresponding to stage IB3. The maximal cross-sectional tumor diameter visualized in any plane is measured both at imaging and at pathologic analysis. The patient is asked to void before scanning to decrease bladder volume. 115 However, in most women with mismatch repair deficiency this is caused by … FDG = fluorodeoxyglucose, FIGO = International Federation of Gynecology and Obstetrics. Staging according to the old systems (ie, FIGO cervical staging systems from 1999, 2009, and 2014) was inaccurate, with 20%–40% of stage IB–IIIB cancers understaged and up to 64% of stage IIIB cancers overstaged (7–9). Dans sa récente Déclaration mondiale sur l'élimination du cancer du col utérin, la FIGO a souligné notre engagement à collaborer à l'effort mondial. MRI is preferred over CT or pelvic examination for measuring primary tumor size. Prognostic Nomograms Predicting Survival in Patients With Locally Advanced Cervical Squamous Cell Carcinoma: The First Nomogram Compared With Revised FIGO 2018 Staging System. However, because tumor is usually homogeneously enhancing similar to normal cervical tissue, CT is usually suboptimal for assessing tumor extent of central pelvic spread and accurate measurement of the tumor (Fig 1) (28). La classification et le pronostic du cancer de l'utérus dépend du grade et du stade de la tumeur. ). Ferlay et al, editors. The examination offers “one-stop staging” by assessing the pelvic tumor with MRI and evaluating the entire body for retroperitoneal nodal and distant metastases. Navigation des articles. If PET/CT is unavailable, then chest radiography is recommended as first-line imaging modality for thoracic imaging. Cancers (Basel). In a paired comparison, a multicenter prospective trial of 153 women showed that PET/CT is more sensitive than is CT alone, especially in depicting lymph nodes in the para-aortic stations (Fig 4, Table 4) (59). Imaging modalities for staging in a range of high- to low-resource practice settings are presented. Elle est maximum entre 60 et 70 ans. 2020 Apr;99(16):e19714. The false-positive rate was also low, but was higher for MRI (8%) than for US (2%; P < .001) (Table 3) (52). L’évaluation du stade d’évolution d’un cancer demande un ensemble de tests de diagnostic et d’examens permettant d’évaluer la nature précise et l’étendue de la maladie. doi: 10.1002/14651858.CD008217.pub3. Source.—References 8 and 9. Figure 1b: Images show uterine cervical cancer at CT versus MRI. 8600 Rockville Pike (a) Contrast--enhanced CT, (b) axial fast spin-echo T2-weighted MRI, and (c) axial T1 images after gadolinium-based contrast agent administration through pelvis of a woman with stage IB2 cervical cancer (arrows). PET/CT is best used to evaluate for hydronephrosis (stage IIIB), retroperitoneal lymphadenopathy (stage IIIC), and distant metastases (stage IVB). Circulating exosomal miR-125a-5p as a novel biomarker for cervical cancer. Dissemination of the advantages of imaging for cervical cancer staging lies within the domain of global health development efforts. Conclusion: Choice of modality depends on the technology available within the practice setting. Patient was staged as IVB based on PET/CT and lymph node biopsy that showed metastases at pathologic analysis. Imagerie de la Femme - Sous presse. a Imaging and pathology can be used, where available, to supplement clinical findings with respect to tumor size and extent, in all stages. ■ Both US and MRI accurately measure the primary tumor and assess parametrial spread better than does CT or physical examination. Most cervical cancers are diagnosed in low-resource settings where options such as modern cross-sectional and functional imaging (eg, CT, MRI, PET/CT), brachytherapy, and on-site pathologic analysis are either constrained or not accessible at all. For instance, the estimated incidence rate of Lynch syndrome in an unselected endometrial cancer population is 3%–6%. Epub 2019 Jul 6. FDG PET/CT examination should be performed in a single sitting in a hybrid scanner in accordance with parameters defined by society guidelines (46). Correlation between FIGO staging, MR imaging staging, and treatment is summarized in , Table 1. (a) Coronal maximal intensity projection PET image in a patient staged as IB following clinical examination and normal chest x-ray (not shown) shows hypermetabolic foci in left upper (arrow) and right middle (arrowhead) thorax corresponding to (b) left supraclavicular lymphadenopathy (arrow) and (c) cavitary right lung nodule (arrowhead), respectively. FIGO et TNM – Cancer de l’endomètre. (a) Coronal maximal intensity projection PET image in a patient staged as IB following clinical examination and normal chest x-ray (not shown) shows hypermetabolic foci in left upper (arrow) and right middle (arrowhead) thorax corresponding to (b) left supraclavicular lymphadenopathy (arrow) and (c) cavitary right lung nodule (arrowhead), respectively. Surgery is the treatment of choice for stages lower than IIA, except for lesions over 4 cm in diameter (stage IB2 or IIA). FIGO = International Federation of Gynecology and Obstetrics. Epub 2020 Nov 18. La fréquence de ce cancer et ses conséquences a régressé depuis 40 ans dans les pays développés grâce au dépistage par frottis. Figure 4b: Images show uterine cervical cancer lymphadenopathy at fluorodeoxyglucose PET/CT versus CT. (a) Coronal maximum intensity projection PET image in a patient clinically staged as IB shows hypermetabolic foci in pelvis (arrowheads) and abdomen (arrows), which at fusion PET/CT (not shown) correspond to retroperitoneal lymphadenopathy. Ceci est un vidéo expliquant la classification du cancer du col utérin. Stages. 6, © 2021 Radiological Society of North America, History of the FIGO cancer staging system, FIGO staging of gynecologic cancer. Administration of intravenous iodinated contrast material is optional but can aid in the evaluation of solid organs (eg, uterine corpus, liver, kidneys). If performed as an alternative to pelvic MRI, then intravenous contrast material should be administered for soft-tissue contrast to aid in distinguishing tumor from the normal uterine and other pelvic tissues. Chaque année, près de 3000 femmes développent un cancer du col de l’utérus et 1000 femmes en meurent. 3 Union for International Cancer Control (UICC). Although this revision acknowledges the progress that the developed countries have made in incorporating imaging for cervical staging to treat patients more effectively and with less morbidity, it also highlights the stark disparities in the care of patients with cervical cancer worldwide.

Pelvic MRI visualizes the primary tumor and evaluates tumor spread into the soft tissues of the central pelvis. The treatment of cervical cancers according to FIGO staging is well defined. Additionally, patients gave consent for data collection and publication. Laisser un commentaire Annuler la réponse. ■ The 2018 International Federation of Gynecology and Obstetrics (FIGO) uterine cervical cancer staging system introduces a new primary tumor size cutoff value of 2 cm (ie, stage IB1 vs IB2), used to evaluate patients for fertility-sparing radical trachelectomy and to estimate prognosis. This site needs JavaScript to work properly. Moyens thérapeutiques 11 A - Chirurgie Version 2.0. Radial spread of tumor out of the uterine cervix into the parametria correlates with stage IIB disease and triages the patient away from primary surgery to concurrent chemotherapy and radiation therapy (Fig 3). † Stage IIIC should be annotated with r (radiology) or p (pathologic analysis) to indicate the method used to allocate this stage. The primary drainage of uterine cervical cancer is to the pelvic sidewall (ie, external iliac, obturator, and internal iliac) and the supraclavicular lymph nodes (23,47). These low-technology choices reflected the demographic reality that nearly 85% of invasive cervical cancer is diagnosed in low-resource settings where advanced imaging modalities are unavailable. Figure 2b: Images show uterine cervical cancer size at US versus MRI. Il est, le plus souvent, diagnostiqué après la ménopause. Keywords: *PET and CT images acquired in a hybrid scanner and interpreted with inclusion of fusion imaging. 114 Routine pathologic screening of mismatch repair deficiencies in the endometrial cancer specimen, similar to colorectal cancer, has been advocated and is increasingly being introduced in practice. Ce cancer est en partie lié a l'activité sexuelle. outils pour les professionnels de santé assurant le suivi gynécologique (INCa). Another prospective multicenter trial showed that the false-negative rate with US and MRI for parametrial extension was comparable and very low (ie, <3%). IB2 invasive carcinoma ≥2 cm and <4 cm in greatest dimension. The first staging system put forth by FIGO around the turn of the 20th century applied to carcinoma of the uterine cervix, at the time the most common cancer among women in the developed world (3). Clinicopathological risk factors in the light of the revised 2018 International Federation of Gynecology and Obstetrics staging system for early cervical cancer with staging IB: A single center retrospective study. 2.1 Stade de la tumeur. With the 2018 International Federation of Gynecology and Obstetrics staging system for uterine cervical cancer, imaging is formally incorporated as a source of staging information and as a supplement to clinical examination (ie, pelvic examination, cystoscopy and colposcopy) to obtain an accurate description of tumor spread. Treatment will involve systemic chemotherapy with local-regional therapy modified to play a less aggressive role. Strictly confined to the cervix; Invades beyond the uterus, but has not extended onto the lower third of the vagina or to the pelvic wall Multiplanar fast spin-echo T2 images help evaluate for tumor invasion into the parametria (stage IIB) and pelvic sidewall (stage IIIB), and images after gadolinium-based contrast agent administration help assess for peritoneal, nodal, and bone metastases (10,32). ║ Abnormalities should be confirmed with pathologic analysis. Le cancer du col de l'utérus - C'est un cancer qui se développe à partir de l'épithélium du col de l'utérus. Table 4: CT versus PET/CT in Detecting Abdominal Retroperitoneal Metastases in Uterine Cervical Cancer. On ne doit pas prendre en compte l’extension au corps utérin. If the address matches an existing account you will receive an email with instructions to reset your password. It is usually performed as part of a PET/CT examination or as an alternative to abdominopelvic MRI if the latter examination is contraindicated or unavailable. Le stade est un classement histopathologique qui décrit le degré d'extension de la tumeur. Classification clinique par stades du cancer du col de l'utérus FIGO* Classification clinique par stades du cancer du col de l'utérus FIGO* Stade. 2021 Jan;21(1):54. doi: 10.3892/ol.2020.12316. Laisser un commentaire Annuler la réponse. Because of its sensitivity in depicting lymph node metastases, PET and PET/CT are a strong predictor of disease-specific survival (15,63). Clinical staging (FIGO) should also be documented (Table 1). Although sensitivity of PET/MRI for pulmonary nodule depiction is suboptimal (ie, depicts 70% nodules seen at CT), it demonstrates high sensitivity (ie, 96%) for depicting FDG-avid nodules (64). First Published: 11 October 2018. The revisions introduced in the 2018 FIGO staging system are intended to address the gap between the staging formalism and ongoing clinical practice and to explicitly acknowledge the role that advanced imaging has come to play in the care of women with invasive uterine cervical cancer (13). Stage IIIC1 corresponds to nodal metastases confined to the pelvis and stage IIIC2 to para-aortic nodal metastases. To be consistent with consensus guidelines for solid tumor measurement, we report tumor involvement as “likely” if the lymph node measures greater than or equal to 1.0 cm and as “almost certainly” if it measures greater than or equal to 1.5 cm in short axis (30). Bray F, Ferlay J, Soerjomataram I, Siegel RL, Torre LA, Jemal A (2018). FIGO et TNM – Cancer de l’endomètre. Dr. Alexandre Ladoux The global scale-up of HPV vaccination and HPV-based screening—including self-sampling—has potential to make cervical cancer a rare disease in the decades to come. Worldwide, every 2 min a woman dies from cervical cancer [].Concerning women, cervical cancer ranks fourth in both frequency and mortality, with approximately 604,000 new cases and 342,000 deaths in 2020 [].The 5-year overall survival of women diagnosed with cervical cancer in Europe is 66%, with a particularly lower percentage of those from Eastern Europe (<55%) []. 2e - Classification des cancers du col de l'utérus. Patients with pelvic and/or para-aortic lymph node metastases are designated as having stage IIIC disease, irrespective of primary tumor size or local pelvic spread. Cancers gynécologiques - Retrouvez les recommandations de bonne pratique liées à la prise en charge des cancers gynécologiques (ovaire, endomètre, col utérin). Results: Am J Obstet Gynecol. Early stage of disease was defined as FIGO stage IA2, IB1 (with tumor diameter < 20 mm) and IB2 (with tumor diameter between 20 and 40 mm) according to the new FIGO 2018 staging system . To be considered a candidate for this procedure, the woman must be considered to have stage I (ie, tumor confined to the cervix) and not stage II (ie, tumor growth into the upper third of the vagina or the parametria) disease. Patients with cervical cancer should be staged according to the TNM classifi cation. Other option for nodal evaluation is surgical and includes lymphadenectomy or sentinel node biopsy, the latter limited to sites where the necessary surgical and pathologic expertise are available (55,56). Deux cas particuliers seront précisés : Cervical cancer continues to be a major public health problem affecting middle-aged women, particularly in less-resourced countries. Moreover, radical trachelectomy, an emerging fertility-preserving technique in which the uterine corpus is anastomosed to the vagina to treat the many women diagnosed during their reproductive years, was not a consideration with these older systems. Ce programme concerne toutes les femmes de 25 à 65 ans, sauf cas particuliers. De fait, la tumeur peut être traitée par une conisation sans que la fertilité puisse en être affectée (figures 2 et 3). If PET/CT is unavailable, then chest radiography is recommended as first-line imaging modality for thoracic imaging. However, in patients with lymphadenopathy, surgery alone does not cure and 10%–30% of patients with early stage disease harbor lymph node metastases (22). Radiologists, among other physicians, should continue to participate in ongoing efforts to improve access to advances in medical technology and expertise in low-resource settings (65,66). FOIA Choice of modality depends on the technology available within the practice setting (Table 2). Diagnostic-quality imaging requires a system greater than or equal to 1.5 T and intravenous contrast material administration. FIGO – Cancer de l’ovaire . The 2018 FIGO staging system for cervical cancer is useful to distinguish survival groups; stage IB1 and stage IB2 disease have distinct characteristics and survival outcomes, while survival in stage IIIC1 varies depending on local tumor factors.
