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 International Committee of Medical Journal Editors (ICMJE) “Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals” (http://www.icmje.org).
COPYRIGHTS AND CREATIVE COMMONS ATTRIBUTION LICENSE
A submitted manuscript, when published, will become the property of the journal. Copyrights of all published materials are owned by the Korean Society of Surgical Oncology. The Creative Commons Attribution Non-Commercial License available from: https://creativecommons.org/licenses/by-nc/4.0/

RESEARCH AND PUBLICATION ETHICS
The journal adheres to the ethical guidelines for research and publication described in the Guidelines on Good Publication (http://publicationethics.org/resources/guidelines
) and the ICMJE Guidelines (http://www.icmje.org
Authorship and Author’s Responsibility
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; and 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. 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. Copyright assignment must be completed by every author.
Originality, Plagiarism, and Duplicate Publication
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.
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 CrossCheck 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 publisher 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.
It is possible to republish manuscripts if the manuscripts satisfy the conditions of secondary publication of the Uniform Requirements for Manuscripts Submitted to Biomedical Journals.
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/
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
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 (https://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.
SUBMISSION & PEER REVIEW PROCESS
Peer Review Process
All manuscripts should be submitted online via the journal’s website (http://submit.kjco.org
) by the corresponding author. Once you have logged into your account, on-line system will lead you through the submission process in a step-by-step orderly process. Submission instructions are available at the website. All articles submitted to the journal must comply with these instructions. Failure to do so will result in return of the manuscript and possible delay in publication.
KJCO reviews all manuscripts received. A manuscripts first reviewed for its format and then sent to the two most relevant investigators 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 by e-mail. 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.
Reporting Guidelines for Specific Study Designs
- The main document with manuscript text and tables should be prepared with an MS-word program.
- The manuscript should be double spaced on 21.6×27.9 cm (letter size) or 21.0×29.7 cm (A4) paper with 3.0 cm margins at the top, bottom, and left margin.
- All manuscript pages are to be numbered consecutively, beginning with the abstract as page 1. Neither the author's names nor their affiliations should appear on the manuscript pages.
- Use only standard abbreviations; use of nonstandard abbreviations can be confusing to readers. Avoid abbreviations in the title of the manuscript. The spelled-out abbreviation followed by the abbreviation in parenthesis should be used on first mention unless the abbreviation is a standard.
- The names and locations (city, state, and country only) of manufacturers of equipment and non-generic drugs should be given.
- When quoting from other sources, give a reference number after the author's name or at the end of the quotation.
- Authors should express all measurements in conventional units, with International System (SI) units.
For the specific study design, such as randomized control studies, it is recommended that the authors follow the reporting guidelines listed in the following table.
Original articles are reports of basic or clinical investigations. Although there is no limitation on the length of these manuscripts, the Editorial Board may abridge excessive illustrations and large tables. The manuscript for an original article should be organized in the following sequence: title page, abstract and keywords, main text (introduction, methods, results, discussion), acknowledgments, references, tables, figure legends, and figures.
- Title page: Include the following items on the title page: 1) the title of the manuscript, 2) author list, 3) names of each author's institutions and an indication of each author's affiliation, 4) the name, address, telephone and fax numbers, and e-mail address of the corresponding author, 5) if necessary, state the source of any research funding and list of where and when the study has been presented in part elsewhere, 6) running title of fewer than 50 characters.
- Abstract and Keywords: The abstract should be concise, less than 250 words, and describe concisely, in a paragraph, Purpose, Methods, Results, and Conclusion of the study in a structured format. Up to 5 keywords should be listed at the bottom of abstract to be used as index terms. For the selection of keywords, refer Medical Subject Heading (MeSH, http://www.ncbi.nlm.nih.gov/mesh).
- Introduction: Briefly describe the purpose of the investigation, including relevant background information.

- Discussion: Observations pertaining to the results of research and other related materials should be interpreted for your readers. Emphasize new and important observations; do not merely repeat the contents of the results. Explain the meaning of the observed opinion along with its limits, and within the limits of the research results connect the conclusion to the purpose of the research. In a concluding paragraph, summarize the result and its meaning.
- Conflict of interest: State any potential conflict of interest that could influence the authors' interpretation of the data, such as financial support from or connections to pharmaceutical companies, political pressure from interest groups, or academically related issues.

- Editorials are invited by the editor and should be commentaries on articles in the current issue. Editorial topics could include active areas of research, fresh insights, and debates in all fields of clinical oncology.
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.
