Onkologija: a medical-scientific journal was established in 1997. It is published on a semi-annual basis (June, December).
The journal publishes original scientific and review articles, clinical case presentations, and clinical guidelines written in the Slovene language. The titles, abstracts, and keywords are translated to English. The journal is double-blind peer reviewed. The journal uses the Open Journal Systems software (OJS) for editorial work and open-access publishing support.
With the aim of facilitating a rapid movement of knowledge within the framework of everyday oncology practice, the multidisciplinary journal deals with all the theoretical and practical aspects of oncology – from primary and secondary prevention and treatment of malignancies, their early detection and treatment, and the rehabilitation and palliation of cancer patients, to various social and ethical problems.
By means of professionally reviewed articles, the journal provides clinicians with the latest information and essential guidelines for the development of their profession, enabling a better understanding and an improved practice within the scope of their professional daily work. By publishing articles in the Slovene language, the journal plays an essential role in the development and enrichment of the Slovene medical terminology.
The editorial board of the journal acts in accordance with the applicable guidelines and recommendations published by the International Committee of Medical Journal Editors (ICMJE), the Committee on Publication Ethics (COPE), the World Association of Medical Editors (WAME), and the Open Access Scholarly Publishers Association in collaboration with Directory of Open Access Journals (DOAJ), COPE, and WAME.
Onkologija is an open access journal, published under the terms of the Creative Commons Attribution License CC-BY 4.0. In accordance with the Budapest Open Access Initiative (BOAI), the journal provides immediate open access to the full articles at the journal’s website (e-archive), encouraging the free availability of research and promoting a greater global exchange of knowledge. The journal and its articles are permanently archived in Digital Repository of Research Organizations of Slovenia (DIRROS) and The Digital Library of Slovenia (dLib.si).
The journal is printed in 10.250 copies and distributed among 10.000+ health professionals who are members of the Medical Chamber of Slovenia, free of charge.

Prior to their publication, all works undergo a double-blind peer review process that is organized independently by the editorial team.
The corresponding author must submit the manuscript electronically using the Open Journal System (OJS).
The authors should adhere to the accepted guidelines and fill in all the sections given. Additional information on the preparation and submission of the mansucript can be found in Instructions for authors for the preparation and submission of the manuscript.
Peer reviewers are carefully selected by editors for their objectivity and scientific knowledge to provide a written assessment of the strengths and weaknesses of a written research, to comment on any ethical concerns raised by the study, to provide the author with useful suggestions for improvement of the manuscript, and to identify and prevent research misconduct, including checking manuscripts for plagiarism, citation manipulation, and data falsification or fabrication. In the process of identifying and dealing with allegations of research misconduct, the journal, editors, and reviewers abide by COPE's guidelines.
The reviewer and the author are anonymous from each throughout the review process. To facilitate this, authors must ensure that their manuscripts are drafted in such a way that they do not reveal their identities to the reviewers, neither directly nor indirectly.
All articles are peer reviewed confidentially by external, professional, courteous, prompt, and constructive experts in the scientific topic addressed. Reviewer anonymity allows for impartial decisions, as the reviewer cannot be influenced by the author. The review must be objective and the critical assessment clearly expressed and supported by arguments. Personal criticism toward the author is unpermissible.
Reviewers should identify the relevant published works that have not been cited by the author. Additionally, the reviewers should also call to the editor's attention any substantial similarity or overlap between the manuscript under consideration and any other published paper which they have personal knowledge of.
Unpublished materials disclosed in a submitted manuscript must not be used in the reviewers’ own research without an express written consent of the author. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should not assess manuscripts in which they might have any conflicts of interest.
The author is obliged to review the improvements, take them into consideration to the largest extent possible, and amend the article within a deadline determined by the editors. Should the author fail to return the article within the set deadline, the article shall be rejected. If the author does not take into account any of the proposed improvements, they must provide the reasons for having done so in writing.
Upon the completion of the peer review process, the author is returned the manuscript with recommendations for improvements in order to check and approve the recommendations proposed and draw up a clean copy. The editors send the clean copy into proofreading.
After the review, the text is formatted by a designer. The author receives the first print and is requested to identify any typing errors. The corrections are to be returned within three days; otherwise, the editors shall deem that the author is satisfied with the first print.
In their work, the editors and the publisher act in accordance with the applicable guidelines and standards defining the mutual roles of all the participants in the publication process, i.e. the authors, editors and the editorial board, reviews, and the publisher:
- Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals, published by The International Committee of Medical Journal Editors (ICMJE),
- The Committee on Publication Ethics (COPE) Guidelines / Core Practices,
- Recommendations on Publication Ethics Policies for Medical Journals, prepared by the Publication Ethics Committee of The World Association of Medical Editors (WAME)
- Principles of Transparency and Best Practice in Scholarly Publishing, published by the Open Access Scholarly Publishers Association in collaboration with DOAJ, COPE and WAME.
The entire peer review and publication process is thorough, objective, and fair. Editorial decisions about a manuscript are based on its importance, originality, clarity, and relevance to the journal's scope and content. The journal has an obligation to its readers and patients to ensure that the research published is accurate and that is adheres to the highest ethical standards.
1.1. Authorship of the article
The journal and editorial board abide by the ICMJE recommendations. An author or co-author is a person who has made substantive intellectual contributions to a published study and the drafting of the article. Authorship is based on the following three criteria: 1) substantial contribution to the conception and design, acquisition of data, or analysis and interpretation of data; 2) involvement in the drafting of the manuscript or the critical revision of its intellectual content; 3) approval of the final published version. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. Additionally, each author is held accountable for ensuring that any questions or doubts relating to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
The corresponding author is the one individual who takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication processes.
When a large multi-author group has conducted the work, all members of the group named as authors should meet the criteria for authorship, including the approval of the final manuscript.
The statements, opinions, and data contained in the journal belong solely to individual authors, not to the publisher and the editors. Neither the publisher nor the editors take any legal responsibility for the errors that may be made.
1.3. Originality and plagiarism
The authors should ensure that their work is original in its entirety. If the authors used other works to obtain data for their article, the referenced work must be appropriately cited or quoted. Plagiarism – regardless of its form – constitutes unethical publishing behaviour and is unacceptable. During the deposit into the DIRROS repository, each document is submitted for the detection of similarity of its content (plagiarism) to all the content on the National Open Science Portal. For plagiarism prevention and detection, the editorial board uses the plagiarism software DPV (Slovene : Detektor podobnih vsebin; English: detector of smilar content). Detailed technical information about the software for plagiarism detection, the process of similar text detection, and the Slovenian national open access infrastructure is available here.
1.4. Disclosure and conflict of interests
A conflict of interest occurs when an individual (author, reviewer, or editor) or its organization is involved in multiple interests, one of which could possibly corrupt the motivation for an act in the other. In their manuscript, all authors should disclose any financial or other substantive conflict of interest that might be construed to influence the results or interpretation of their manuscript. All sources of financial support for the project should be clearly disclosed. Potential conflicts of interest should be disclosed at the earliest stage possible.
1.5. Potential hazards to human or animal subjects
If their work involves chemicals, procedures, or equipment that have any unusual hazards inherent in their use, the author must clearly specify them in the manuscript. If the work involves the use of animal or human subjects, the author should ensure that the manuscript contains a statement that all procedures were performed in compliance with the relevant laws and institutional guidelines, and that the National Medical Ethics Committee of the Republic of Slovenia has approved them. The research described in the papers submitted to the editors must adhere to the principles of the Helsinki Declaration (a statement of ethical principles for medical research involving human subjects). The author should include a statement in the manuscript that informed consents were obtained for experimentation with human subjects. The right of a person to privacy must always be respected.
1.6. Data access and retention
Authors may be asked by the editors to provide the raw data used in the drafting of their publication. Additionally, authors should be prepared to provide public access to such data and retain such data for three years after publication.
1.7. Multiple, redundant, or concurrent publication
An author should not, in general, publish manuscripts describing essentially the same research in more than one journal or primary publication. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behaviour and is unacceptable. Publication of some kinds of articles (e.g. clinical guidelines) in more than one journal is sometimes justifiable, provided certain conditions are met. The authors and editors of the journals concerned must agree to the secondary publication, which must reflect the same data and interpretation of the primary document. The primary reference must be cited in the secondary publication.
1.8. Acknowledgement of sources
References must be cited appropriately. Authors must always cite the works of others. They should cite all publications that have been influential in determining the nature of the reported work. Information obtained privately through conversation or correspondence with third parties must not be used or reported without an explicit written permission from the source. References must be cited in accordance with the guidelines of the editors.
1.9. Correction or retraction policy
When an author discovers a significant error or inaccuracy in their own published work, it is the author’s obligation to promptly notify the editor to publish a correction. If the editor and/or publisher learn from a third party that a published work contains a significant error, it is the obligation of the editor and/or publisher to notify the author to promptly retract or correct the paper or provide evidence of the correctness of the original paper.
1.10. Standards of reporting
Authors of reports of original research should present an accurate account of the work performed as well as an objective discussion of its significance. Underlying data should be represented accurately in the paper. The paper should contain sufficient detail and references to permit others to replicate the work. Fraudulent or knowingly inaccurate statements constitute unethical behaviour and are unacceptable. Review and professional publication articles should also be accurate and objective.
2.1. Publication decisions
The editor of a peer-reviewed journal is responsible for selecting the articles submitted and deciding upon their publication. Such decisions must always be driven by the validation of the work in question and its importance to researchers and readers. The editor may be guided by the policies of the journal's editorial board and constrained by such legal requirements as shall then be in force regarding libel, copyright infringement and plagiarism. The editor may discuss the publication of a work with other editors, reviewers, and members of the editorial board.
2.2. Fair play
The editor should evaluate manuscripts based on their intellectual content, with no regard to race, gender, sexual orientation, religious belief, ethnic origin, citizenship, political philosophy, or the world view of the authors.
The editor and other members of the editorial board must not disclose any information about a submitted manuscript to anyone but the adequate author, reviewers and potential reviewers, other editors, or the publisher, whenever that is appropriate.
2.4. Disclosure and conflicts of interest
Unpublished materials disclosed in a submitted manuscript must not be used in an editor's own research without an express written consent of the author. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Editors should recuse themselves from considering manuscripts in which they have conflicts of interest (competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers). Editors should require all contributors to disclose relevant competing interests and publish corrections if competing interests are revealed after publication. If needed, other appropriate action should be taken, such as the publication of a retraction or expression of concern. The peer-review process is confidential and is the same for all the submitted manuscripts. Non-peer reviewed sections of the journal should be clearly identified.
2.5. Involvement and cooperation in investigations
The editor should take reasonably responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper. Such measures will generally include contacting the author of the manuscript or the relevant institutions and research bodies, and if the complaint is upheld, the publication of a correction, retraction, expression of concern, or other note, as may be relevant. Every reported act of unethical publishing behaviour must be looked into, even if it is discovered years after publication.
