METHODS Consecutive patients diagnosed with bilateral small renal masses (synchronous or metachronous) of a defined geographical area were recorded in a large database (TUCAN database) between January 2005 and December 2016. Patients had a unique identifier number and followed during this period using an agreed upon protocol. Clinicopathological characteristics and outcomes of bilateral small renal masses on active surveillance were analysed and compared to propensity score matched sporadic unilateral small renal masses. Data were analysed for renal mass growth rate, rate of intervention and development of metastatic disease and patient survival. RESULTS A total of 1600 patients were diagnosed with renal cancer, of which bilateral small renal masses accounted for 70 (6.6%) cases. Synchronous SRMs were observed in 63 patients, whereas metachronous lesions were found in seven patients during the study period. Metachronous lesion mean time to appearance was 62 ± 41 months (range, 9 to 149 months). While most cases were sporadic, four were found to be hereditary. Growth rate of bilateral small renal masses did not differ from that of unilateral sporadic small renal masses. Similarly, there were no between group differences for rate of interventions and survival. CONCLUSIONS Progression, rate of metastases and survival for patients diagnosed with bilateral small renal masses is similar to those diagnosed with unilateral disease. © 2018FiguresReferencesRelatedDetails Volume 199Issue 4SApril 2018Page: e978 Advertisement Copyright & Permissions© 2018MetricsAuthor Information Nissar Sheikh More articles by this author Mohammad Khan More articles by this author stephen Lang More articles by this author Sanjay Pillai More articles by this author Ghulam Nabi More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
