OBJECTIVE: To update the recommendations for the management of kidney cancers.
METHODS: A systematic review of the literature was conducted from 2015 to 2022. The most relevant articles on the diagnosis, classification, surgical treatment, medical treatment and follow-up of kidney cancer were selected and incorporated into the recommendations. Therefore, the recommendations were updated while specifying the level of evidence (high or low).
RESULTS: The gold standard for the diagnosis and evaluation of kidney cancer is contrast-enhanced chest and abdominal CT. MRI and contrast-enhanced ultrasound are indicated in special cases. Percutaneous biopsy is recommended in situations where the results will influence the therapeutic decision. Renal tumours should be classified according to the pTNM 2017 classification, the WHO 2022 classification and the ISUP nucleolar grade. Metastatic kidney cancer should be classified according to the IMDC criteria. Partial nephrectomy is the gold standard treatment for T1a tumours and can be performed by an open approach, by laparoscopy or by robot-guidance. Active surveillance of tumours less than 2cm in size can be considered regardless of the patient\'s age. Ablative therapies and active surveillance are options in elderly patients with comorbidity. T1b tumours should be treated by partial or radical nephrectomy depending on the complexity of the tumour. Radical nephrectomy is the first-line treatment for locally advanced cancers. Adjuvant treatment with pembrolizumab should be considered in patients at intermediate and high risk for recurrence after nephrectomy. In metastatic patients: Immediate cytoreductive nephrectomy may be offered to oligometastatic patients in combination with local treatment of metastases if this can be complete and delayed cytoreductive nephrectomy can be proposed for patients with a complete response or a significant partial response. Medical treatment should be proposed as first-line therapy for patients with a poor or intermediate prognosis. Surgical or local treatment of metastases can be proposed in case of single or oligo-metastases. The recommended first-line drugs for metastatic patients with clear cell renal carcinoma are the combinations axitinib/pembrolizumab, nivolumab/ipililumab, nivolumab/cabozantinib and lenvatinib/pembrolizumab. Cabozantinib is the recommended first-line treatment for patients with metastatic papillary carcinoma. Cystic tumours should be classified according to the Bosniak classification. Surgical removal should be proposed as a priority for Bosniak III and IV lesions. It is recommended that patient monitoring be adapted to the aggressiveness of the tumour.
CONCLUSIONS: These updated recommendations are a reference that will allow French and French-speaking practitioners to improve kidney cancer management.

The extraordinary and unexpected success of cellular immunotherapy using genetically engineered T-cells to express a chimeric antigen receptor (CAR) targeting CD19, in the treatment of refractory or relapsing B-hematological malignancies, has provided a real therapeutic hope. Indeed, remission rates reach more than 80 % in patients at a stage, without any other possibilities of treatment, notably in the child\'s acute lymphoblastic leukemia. These results, initially resulting from academic research, led to Food and Drug accreditation for market access of two innovative autologous therapy drugs, Kimryah® and Yescarta®. Based on the impressive clinical results, mainly so far in hematological malignancies (LAL, MM, LBDGC, etc.), the development of several types of cells expressing a CAR receptor suggests a wide range of future applications, particularly in the field of solid tumors. However, while the development of CAR-T cells now appears to be in the hands of private pharmaceuticals companies, the logistical constraints, the cryopreservation and the very high cost of these personalized medicines may ultimately limit their use. The development of academic productions by CAR-T cells could bypass some of these disadvantages. The strong innovation capacity of healthcare institutions associated with research units allows them to identify the ideal tumor target and efficient performing cells. Thus, authorized production platforms could allow for shorter administration times and reasonable production costs for national health systems. The aim of this workshop is to identify the requirements for the academic production of CAR-T cells, while respecting the research standards useful to establish proof of concept, but also at the preclinical development stage, leading in fine to the manufacture, through an authorized pharmaceutical establishment, of the innovative therapy drug, and in accordance with Good Manufacturing Practice (GMP). The ultimate goal is to make these innovative and high-performance medicines available to as many patients as possible.

Improved knowledge of sentinel node procedures coupled with the results of adjuvant clinical trials in stage III melanoma have prompted the French Cutaneous Oncology Group to propose new guidelines for the management of stage III melanoma. These guidelines comply with the principles of the evidence-based medicine.

Advanced renal cell carcinoma (RCC) is associated with a poor prognosis and is refractory to standard chemotherapy. Recent progress in the understanding of molecular biology and pathogenesis of renal cell cancer has been translated into the development of new therapeutic strategies. The management of metastatic RCC has been revolutionized with the development of targeted molecular therapies against VEGF-VEGFR and mTOR. Randomized phase III clinical trials demonstrated clinical benefit for patients with advanced RCC in overall survival and progression free survival. Guidelines for the management of side effects induced by these targeted therapies seem to be warranted.
