The authors would like to draw the reader's attention to an error in the following article:

Shinohara N, Nonomura K, Abe T, Maruyama S, Kamai T, Takahashi M, Tatsugami K, Yokoi S, Deguchi T, Kanayama H, Oba K, Naito S. A new prognostic classification for overall survival in Asian patients with previously untreated metastatic renal cell carcinoma. Cancer Sci 2012; 103: 1695–700.

On page 1698, Figure 2's legend should have read:

Overall survival stratified by JMRC prognostic classification (n = 323) into good risk group, intermediate risk group, and poor risk group; 38 patients for whom one or more of the risk factors were missing were excluded.

The authors apologize for this error and any confusion it may have caused.
