Plagiarism Review Process
If the similarity exceeds 25% or if substantial plagiarism is confirmed, the manuscript will be rejected. Authors will be informed of the decision, and in severe or repeated cases, further action may be considered.
Plagiarism Check Timing
All manuscripts submitted to the European Journal of Oncology are screened for plagiarism immediately after submission and before the peer-review process begins.
Handling Plagiarism
- Less than 5%: Considered minor overlap. The manuscript is assigned an ID and sent to the authors for revision.
- 5–30%: Considered significant overlap. The manuscript is not assigned an ID and is returned to the authors for substantial revision.
- Above 30%: Considered unacceptable. The manuscript is rejected prior to review. Authors may revise and resubmit as a new submission.
Plagiarism Detected After Publication
If plagiarism is identified after an article has been published, the European Journal of Oncology will initiate a formal investigation. Confirmed cases may result in retraction, institutional notification, or marking the article as plagiarized.
Commitment to Original Research
By submitting a manuscript to the European Journal of Oncology, authors affirm that the work is original, unpublished, and not under consideration elsewhere. The journal prohibits plagiarism in all forms, including self-plagiarism and duplicate publication. All submissions may be screened with plagiarism-detection software.
Forms of Plagiarism
- Copying substantial content directly from other sources without citation.
- Reusing another author’s text, figures, or tables without acknowledgment.
- Using online content (text, images, graphics) without citing the source.
- Reproducing diagrams, photographs, or illustrations without permission.
Acknowledging Authors’ Sources
Proper citation of all sources is mandatory. Self-plagiarism is not permitted except when reusing content from prior work (e.g., conference proceedings) with clear citation.
Accidental or Unintentional Plagiarism
Even if unintentional, plagiarism remains the author’s responsibility. Authors must understand proper quoting, paraphrasing, and citation to avoid ethical violations.
Reporting Plagiarism
If plagiarism is suspected in a published article, it should be reported to the editorial office. All reports are investigated, and serious cases may result in article retraction.
