Erratum to: Int J Clin Oncol DOI 10.1007/s10147-015-0923-3

Unfortunately, the name of the sixth author was incorrectly published in the original article. The corrected author’s name (Kunihiko Yoshioka) is published with this erratum.

Also, in the abstract, introduction and footnotes of tables, “prostate serum antigen (PSA)” should read “prostate specific antigen (PSA)”.
