Dual-energy SPEctral CT to Evaluate Response to New First-line Therapies in Patients With Metastatic Clear Cell REnal Cancer and the Association of Its Parameters With Molecular Alterations
To evaluate the utility of dual-energy spectral computed tomography (CT) scan in monitoring treatment in patients with metastatic clear cell carcinoma of the kidney. In particular, to analyze the use of spectral CT in patients who are candidates to receive first-line treatment based on combinations of immunotherapy and molecularly targeted drugs. In particular, the parameters derived from the use of this technology and their variation during therapy will be analyzed together with some possible molecular alterations highlighted by the analysis of the tumor tissue previously taken from the patient, relating them to the response to first-line therapy with immuno-combinations.
• Age ≥ 18 years
• Patients with histological or cytological diagnosis of clear cell RCC
