Prognosis of patients with stage T1 and T2 renal cell carcinoma according to tumor size

In an attempt to define the relationship between tumor size and survival, the records of 307 patients with renal cell carcinoma were analyzed. Larger tumors were associated with a worse survival in T1-2 patients. When T1-2 patients were divided according to a tumor size of 70 mm, there was a statistically significant difference between the two groups (p = 0.01). There was no statistically significant difference between T1 and T2 patients divided according to a tumor size of 25 mm (p = 0.15). It would thus seem to be more appropriate to divide T1 and T2 patients into two groups according to a tumor size of 70 mm rather than 25 mm.
