    Abstract:
    PURPOSE: Incidental detection of small renal masses has increased in recent years with increased use of various imaging modalities, and a substantial number of diagnoses are made in the elderly population. Minimally invasive surgical procedures have previously been established as options with excellent long-term oncological results, but surveillance strategies have more recently been introduced as alternatives for surgical intervention. This study reviews the outcomes for elderly patients treated with observation or surgery for small renal masses in order to better elucidate optimal management strategies. METHODS: A total of 4647 patients from the SEER database met criteria for inclusion in this study. Cumulative incidences of RCC-specific mortality and non-RCC-related mortality were estimated, and frequency distributions by tumor size and surgical status were calculated. RESULTS: No difference in RCC-related mortality was observed among all treatment groups, including surveillance, for tumors 1-30 mm in size. RCC-related mortality was significantly lower for surgically treated patients for all other tumor size groups. Mortality unrelated to RCC was significantly higher in patients undergoing surveillance compared to those undergoing surgical intervention for tumor sizes 1-30 or 1-40 mm. CONCLUSIONS: A small renal mass in patients of 80+ years of age is best defined as up to 3 cm in size. For these patients, observation appears be a valid, if not preferential strategy. Patients 80+ years of age with renal masses greater than 3 cm still appear to benefit from surgical intervention.
