Renal cell carcinoma: staging and surveillance

摘要

Renal cell carcinoma is a common malignancy with many histologic subtypes. Appropriate treatment depends not only upon the specific subtype but also the size of the tumor and extent of spread at time of presentation. Approximately 5% of RCCs are part of a hereditary syndrome which must also be considered in the therapeutic decisions. Although some RCCs are detected with ultrasound, CT or MR is required for staging. CT is used most commonly as it is most readily available and relatively less expensive than MR imaging. The TNM classification of the American Joint Committee on Cancer has largely replaced the Robson classification. Early detection, accurate staging, and improved treatment options have resulted in improved 5-year survival of patients with renal carcinoma.
