Abstract
The increased use of cross-sectional imaging has led to significant stage migration in renal cell carcinoma (RCC). As more computed tomography (CT) and magnetic resonance imaging scans are performed for unrelated conditions, more RCCs have been detected – particularly small, asymptomatic lesions. For larger RCCs, obtaining chest imaging to rule out synchronous lung metastasis (sLM) remains an important clinical principle, supported by current guidelines. However, regarding chest imaging, guidelines do not necessarily reflect the stage migration in RCC over the past decade. 1 Campbell S Uzzo RG Allaf ME et al.
