Tumor size of renal cell carcinoma: its clinical implication

We studied the clinical implication of tumor size in renal cell carcinoma, by revealing its relation with the other histopathological and clinical features. The tumor size was well correlated with histopathological findings and metastatic status of the carcinoma. Smaller carcinomas (usually less than 60 mm) generally had a higher disease-specific survival than those of 60 mm or greater. The results indicated that the size reflected the biological character of the carcinoma. However, 10% of patients with the smaller carcinoma had lymph node metastasis or distant metastasis at the time of diagnosis, each of which contributed to a renal cell carcinoma-related death in the early follow-up period.
