Retraction note: Efficacy and safety analysis of transarterial chemoembolization and transarterial radioembolization in advanced hepatocellular carcinoma descending hepatectomy

Abstract

The retraction note addresses allegations concerning the published article titled “Efficacy and safety analysis of transarterial chemoembolization and transarterial radioembolization in advanced hepatocellular carcinoma descending hepatectomy”. World J Gastrointest Surg 2023; 15: 687-697. To preserve academic integrity and avoid misleading the readers, the authors agreed to retract the article, due to significant concerns regarding the reliability of the transarterial radioembolization data obtained by exploratory, non-standardized interventional procedures and ethical compliance in this study, which severely damaged the conclusion in this study. The authors sincerely apologize to the readers, reviewers and editors for these errors and for any inconvenience caused by this retraction.

RETRACTION NOTE

We have thoroughly reviewed the allegations regarding our published article, titled "Efficacy and safety analysis of transarterial chemoembolization and transarterial radioembolization in advanced hepatocellular carcinoma descending hepatectomy," published in World Journal of Gastrointestinal Surgery (Vol. 15, Issue 4, 2023)[1].

We fully recognize the significant concerns regarding the timeline discrepancy of the transarterial radioembolization (TARE) procedure in China and the authenticity of the submitted ethical approval documents. After conducting an internal review and engaging in discussions with the relevant hospital ethics committee, we would like to offer the following clarifications and decisions.

TIMELINE OF TARE PROCEDURE IMPLEMENTATION

Concerning the timeline discrepancy of TARE procedure described in the article (2016-2021) and its actual introduction in China (2022), we acknowledge that ambiguity in the procedural definitions and timelines may lead to misunderstandings about the clinical application of TARE mentioned in the study. Upon careful re-examination, the term “TARE” in this study encompassed exploratory, non-standardized interventional procedures conducted prior to the formal adoption of TARE technology in China (2022). Consequently, the data cannot be reliably attributed to the current standardized TARE protocol and the conclusions drawn from this cohort are not that valid. We deeply regret this omission and take full responsibility for the confusion it has caused.

ETHICAL APPROVAL DOCUMENT ISSUES

With regard to the concerns about the ethical approval documents, we accept full responsibility for the errors and potential irregularities found in these documents. These issues likely arose due to technical errors during the organization and submission of the materials, or due to discrepancies in file transfers. While the study was conducted in accordance with ethical principles, the inability to provide complete and verifiable documentation necessitates retraction to uphold the highest standards of research integrity.

DECISION TO WITHDRAW THE ARTICLE

While we remain confident in the scientific rigor underlying the research, we recognize that the current situation could adversely impact the academic reputation of both the authors and the journal. To prevent further misunderstandings and avoid unnecessary disputes, we have decided to withdraw the manuscript. This decision is made in the interest of preserving the integrity of the academic process and maintaining a transparent and credible research environment.

Should additional information or documentation be required, we are fully prepared to cooperate and provide the necessary materials. Please do not hesitate to contact us if further actions are needed on our part.

Thank you for your understanding and continued support in upholding the integrity of scientific research.
