The Editor and Publisher of Cancer Management and Research wish to retract the published article.
The journal was notified of discrepancies in Table 2 for the Depth of invasion numbers reported. The total number of cases was reported as 70, however the number of cases recorded for the Relative CASC 9 Expression (n = 29 (Low); n = 41 (High)) was inconsistent with the grouping values provided (n = 34 (Low); n = 36 (High)). The authors were unable to provide a satisfactory explanation for this discrepancy and were also unable to provide satisfactory raw data for the study reported.
The editor determined the findings of the study were no longer valid and requested for the article to be retracted.
The authors wish to apologise for this error.
Our decision-making was informed by our policy on publishing ethics and integrity and the COPE guidelines on retraction.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
