SynchronouS pulmonary metaStaSeS from renal cell carcinoma - a whole nation Study on prevalence and potential reSectability
2012
Background:At the time of diagnosis, almost one third of patients with renal cell carcinoma (RCC) have metastasis. We studied the prevalence, survival, and potential resectability of synchronous pulmonary metastases (SPMs) in a well-defined cohort of RCCpatients.Material and Methods:Aretrospective whole nation study including RCC patients with SPM diagnosed 1970–2005 in Iceland. Imaging studies and histology were reviewed, the TNM system used for staging the primary tumors, and disease-specific survival estimated. Eligibility for SPM removal was evaluated using different criteria from the literature on surgical management of SPM, including solitary SPM and SPMs confined to one lung.Results:Altogether, 154 patients (16.9%) had SPMs. In 55 of these patients (35.7%) the lungs were the only site, with detailed information available in 46 cases. Of these 46 patients with SPMs, 15 were unilateral, and of those 11 were solitary. All of these 11 patients were in good physical condition and were deemed eligible fo...
