The Korean Journal of Clinical Oncology (Korean J Clin Oncol, KJCO) is an official publication of the Korean Society of Surgical Oncology. KJCO serves its readers as the single most credible, authoritative resource for disseminating significant clinical oncology research. Its scope comprised the followings: gastrointestinal, breast, head and neck cancer and soft tissue tumor including other organs tumors; molecular oncology; cancer prevention; clinical trial for chemotherapy; supportive care and quality of life issues. Its publication types include original articles, reviews, case reports, correspondences, and editorials. The journal is published biannually (30th June, 31st December) and distributed to members of the Korean Society of Surgical Oncology, medical school, libraries and related institutes to pursue the academic advancement in clinical oncology and to promote an active communication between the members and international societies of clinical oncology. Eventually, the Journal aims to cure of cancer and improvement of public health. Manuscripts for submission to KJCO should be prepared according to the following instructions. For issues not addressed in these instructions, the author is referred to the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals (http://www.icmje.org/icmje-recommendations.pdf) from the International Committee of Medical Journal Editors (ICMJE).
RESEARCH AND PUBLICATION ETHICS
The journal adheres to the guidelines and best practices published by professional organizations, including ICMJE Recommendations and the Principles of Transparency and Best Practice in Scholarly Publishing (joint statement by the Committee on Publication Ethics, COPE; the Directory of Open Access Journals, DOAJ; the World Association of Medical Editors, WAME; and Open Access Scholarly Publishers Association, OASPA; https://doaj.org/bestpractice
). Furthermore, all processes of handling research and publication misconduct shall follow the applicable COPE flowchart (https://publicationethics.org/resources/flowcharts
Authorship and Author’s Responsibility
Originality, Plagiarism, and Duplicate Publication
Authorship credit should be based on 1) substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data; 2) drafting the article or revising it critically for important intellectual content; 3) final approval of the version to be published; and 4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. Authors should meet these four conditions.
- A list of each author’s role and ORCID ID should accompany the submitted paper.
- Correction of authorship: After the initial submission of a manuscript, any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors on the paper. Once a manuscript is accepted for publication we do not allow changes in the author list.
- Role of corresponding author: The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process, and typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest forms and statements, are properly completed, although these duties may be delegated to one or more coauthors. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely manner, and should be available to respond to critiques of the work and cooperate with any requests from the journal for data or additional information or questions about the paper even after publication.
- KJCO does not allow multiple corresponding authors for one article. Only one author should correspond with the editorial office and readers for one article. KJCO does accept notice of equal contribution for the first author when the study was clearly performed by co-first authors. There is no limitation on the number of authors.
- Contributorship: Any researcher, who does not meet all four ICMJE criteria for authorship discussed above but contribute substantively to study in terms of idea development, manuscript writing, conducting research, data analysis, and financial support should have their contributions listed in the ‘Acknowledgments’ section of the article. We encourage authors to fully acknowledge the contribution of patients and the public to their research where appropriate.
Submitted manuscripts must not have been previously published or be under consideration for publication elsewhere. No part of the accepted manuscript should be duplicated in any other scientific journal without the permission of the Editorial Board. Submitted manuscripts are screened for possible plagiarism or duplicate publication by Similarity Check upon arrival. If plagiarism or duplicate publication related to the papers of this journal is detected, the manuscripts may be rejected, the authors will be announced in the journal, and their institutions will be informed. There will also be penalties for the authors. A letter of permission is required for any and all material that has been published previously. It is the responsibility of the author to request permission from the copyright holder for any material that is being reproduced. This requirement applies to text, figures, and tables published by any of the authors themselves or used from another source, unless it is in the public domain.
Conflict of Interest Statement
The corresponding author must inform the editor of any potential conflicts of interest that could influence the authors’ interpretation of the data. Examples of potential conflicts of interest are financial support from or connections to pharmaceutical companies, political pressure from interest groups, and academically related issues. In particular, all sources of funding applicable to the study should be explicitly stated.
Registration of Clinical Trial Research
Statement of Informed Consent and IRB Approval
It is recommended that any research that deals with a clinical trial be registered with a primary national clinical trial registration site, such as http://cris.nih.go.kr/, or other sites accredited by the WHO as listed at http://www.who.int/ictrp/en/
, or ClinicalTrials.gov (http://clinicaltrials.gov/
), a service of the United States National Institutes of Health.
Copies of written informed consent and Institutional Review Board (IRB) approval for clinical research should be kept. If necessary, the editor or reviewers may request copies of these documents to resolve questions about IRB approval and study conduct. In addition, for studies conducted with human subjects, the method by which informed consent was obtained from the participants also needs to be stated in the Methods section.
Statement of Human and Animal Rights
Process for Managing Research and Publication Misconduct
Clinical research should be conducted in accordance with the WMA Declaration of Helsinki: Ethical Principles for Medical Research Involving Human Subjects (https://www.wma.net/what-we-do/medical-ethics/declaration-of-helsinki/
). Clinical studies that do not meet the Helsinki Declaration will not be considered for publication. For human, identifiable information, such as patients’ names, initials, hospital numbers, dates of birth, or other protected healthcare information should not be disclosed. For animal subjects, research should be performed based on the National or Institutional Guide for the Care and Use of Laboratory Animals, and the ethical treatment of all experimental animals should be maintained.
When the journal faces suspected cases of research and publication misconduct such as redundant (duplicate) publication, plagiarism, fraudulent or fabricated data, changes in authorship, an undisclosed conflict of interest, ethical problems with a submitted manuscript, a reviewer who has appropriated an author’s idea or data, complaints against editors, and so on, the resolution process will follow the flowchart provided by the Committee on Publication Ethics (http://publicationethics.org/resources/flowcharts
). The discussion and decision on the suspected cases are carried out by the Editorial Board.
The Editorial Board will continuously work to monitor and safeguard publication ethics: guidelines for retracting articles; maintenance of the integrity of the academic record; preclusion of business needs from compromising intellectual and ethical standards; publishing corrections, clarifications, retractions, and apologies when needed; and excluding plagiarism and fraudulent data. The editors maintain the following responsibilities: responsibility and authority to reject and accept articles; avoiding any conflict of interest with respect to articles they reject or accept; promoting publication of corrections or retractions when errors are found; and preservation of the anonymity of reviewers.
Description of Participants
Ensure correct use of the terms sex (when reporting biological factors) and gender (identity, psychosocial or cultural factors), and, unless inappropriate, report the sex and/or gender of study participants, the sex of animals or cells, and describe the methods used to determine sex and gender. If the study was done involving an exclusive population, for example in only one sex, authors should justify why, except in obvious cases (e.g., prostate cancer). Authors should define how they determined race or ethnicity and justify their relevance.
COPYRIGHTS, OPEN ACCESS, DATA SHARING, ARCHIVING POLICY
Copyright in all published material is owned by the Korean Society of Surgical Oncology. Authors must agree to transfer copyright during the submission process. The corresponding author is responsible for submitting the copyright transfer agreement to the publisher.

PEER REVIEW AND PUBLICATION PROCESS
Screening Before Review
If the manuscript does not fit the aims and scope of the Journal or does not adhere to the Instructions to Authors, it may be returned to the author immediately after receipt and without a review. Before reviewing, all submitted manuscripts are inspected by Similarity Check powered by iThenticate (https://www.crossref.org/services/similarity-check/), a plagiarism-screening tool. If a too high a degree of similarity score is found, the Editorial Board will do a more profound content screening. The criterion for similarity rate for further screening is usually 15%; however, the excess amount of similarity in specific sentences may be also checked in every manuscript. The settings for Similarity Check screening are as follows: It excludes quotes, bibliography, small matches of 6 words, and small sources of 1%.
Peer Review Process
After screening, a manuscript sent to the 2 most relevant reviewers of the field. In addition, if deemed necessary, a review of statistics may be requested. Authors' names and affiliations are removed during peer review. The acceptance criteria for all papers are based on the quality and originality of the research and its clinical and scientific significance. Acceptance of the manuscript is decided based on the critiques and recommended decision of the referees. An initial decision will normally be made within 4 weeks of receipt of a manuscript, and reviewers’ comments are sent to the corresponding authors. Revised manuscripts must be submitted online by the corresponding author. The corresponding author must indicate the alterations that have been made in response to the referees’ comments item by item. Failure to resubmit the revised manuscript within 8 weeks of the editorial decision is regarded as a withdrawal. A final decision on acceptance for publication or rejection for publication is forwarded to the corresponding author from the Editorial Office.
Appeals of decisions: Any appeal against an editorial decision must be made within 2 weeks of the date of the decision letter. Authors who wish to appeal a decision should contact the Editor-in-Chief, explaining in detail their reasons for their appeal. All appeals will be discussed with at least one other associate editor. If consensus cannot be reached thereby, an appeal will be discussed at a full editorial meeting. The process of handling complaints and appeals follows the guidelines of the Committee of Publication Ethics available form (https://publicationethics.org/appeals). KJCO does not consider second appeals.
FINAL PREPARATION FOR PUBLICATION
After the paper has been accepted for publication, the author(s) should submit the final version of the manuscript. The names and affiliations of the authors should be double-checked and if the originally submitted image files were of poor resolution, higher resolution image files should be submitted at this time. The EPS, JPG, PPT, TIF formats are preferred for submission of digital files of photographic images. Symbols (e.g., circles, triangles, squares), letters (e.g., words, abbreviations), and numbers should be large enough to be legible on reduction to the journal’s column widths. All symbols must be defined in the figure caption. If references, tables, or figures are moved, added, or deleted during the revision process, renumber them to reflect such changes so that all tables, references and figures are cited in numeric order.
Before publication, the manuscript editor will correct the manuscript such that it meets the standard publication format. The author(s) must respond within 2 days when the manuscript editor contacts the author for revisions. If the response is delayed, the manuscript’s publication may be postponed to the next issue.
The author(s) will receive the final version of the manuscript as a PDF file. Upon receipt, within 2 days, the editorial office (or printing office) must be notified of any errors found in the file. Any errors found after this time are the responsibility of the author(s) and will have to be corrected as an erratum.
Errata and Corrigenda
To correct errors in published articles, the corresponding author should contact the journal’s Editorial Office with a detailed description of the proposed correction. Corrections that profoundly affect the interpretation or conclusions of the article will be reviewed by the editors. Corrections will be published as corrigenda (corrections of author’s errors) or errata (corrections of publisher’s errors) in a later issue of the journal.
ARTICLE PROCESSING CHARGES
For unsolicited manuscripts, the corresponding author is asked to pay for a part of the costs of article processing. The processing charge for an article is 100,000 Korean won (US $100) regardless of the type of article (Woori Bank 1005-901-283811/ Korean Society of Surgical Oncology).
