INTRODUCTION: The purpose of this study was to propose an update of the French guidelines from the national committee ccAFU on upper tract urothelial carcinomas (UTUC).
METHODS: A systematic Medline search for epidemiology, risk factors, diagnosis, prognosis, treatment options and follow-up of UTUC was performed between 2022 and 2024 to evaluate available references and their levels of evidence.
RESULTS: UTUC is a rare malignancy with specific risk factors, including exposure to aristolochic acid and Lynch syndrome. Its diagnosis is based on the use of computed tomography urography and ureterorenoscopy with biopsies. A prognostic classification has been proposed to discriminate low- and high-risk lesions mainly on the basis of tumour grade (low/high) and imaging aspects (non-invasive/invasive). Tumour size (<2/≥2cm), focality (uni-/multifocal), and hydronephrosis (absent/present) are more relative risk factors. The standard of care for low-risk patients is currently conservative treatment involving ureterorenoscopy laser ablation, whereas radical nephroureterectomy (RNU) is advised for those with high-risk disease. Adjuvant treatments after RNU include intravesical instillation of chemotherapy to decrease the risk of bladder recurrence and delivery of platinum-based chemotherapy in pT2-T4 and/or pN+ patients. First-line treatment for metastatic UTUC is based on the combination of enfortumab vedotin plus pembrolizumab. For unfit patients, platinum-based chemotherapy plus nivolumab followed by maintenance nivolumab or platinum-based chemotherapy followed by maintenance avelumab in those with at least stable disease can be proposed. The surveillance regimen and schedule depend on the disease stage.
CONCLUSION: These updated guidelines will contribute to improving the management of patients diagnosed with UTUC.
