Kidney cancer
Brief summary
Kidney cancer in adults is the seventh leading cause of cancer-related death in France. Early and accurate imaging of the primary tumour and the identification of metastatic sites are major prognostic factors that are crucial for determining the appropriate stage-specific treatment. However, the diagnosis of sub-centimetre metastatic lymph nodes and occult metastatic lesions remains difficult with current imaging methods. Recent publications have shown promising results for 68Ga-PSMA PET-CT in the detection of metastases from renal cell carcinoma (RCC). It is therefore necessary to develop a new, more sensitive and specific imaging method to detect occult metastatic foci, enabling the earlier initiation of specific systemic or local treatment, and thereby improving survival in these patients or even achieving prolonged remission in oligometastatic cases Experience and acceptability of a new organisational model in primary care: participatory multi-professional health centres

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| classification of the lesion as 'malignant' or 'benign' | 1 month | The value of 68Ga-PSMA PET-CT will be determined by the number of patients for whom: * at least one lesion classified as 'malignant' on PET is not visible or is classified as 'benign' on the reference imaging, or * at least one lesion classified as 'malignant' by the reference imaging is ruled out (classified as 'benign') on PET. The 'malignant'/'benign' classification of the lesion is based on 68Ga-PSMA PET-CT and on the reference imaging, |
