NOWOTWORY Journal of Oncology publishes papers which cover all aspects of oncology but concentrates on clinical studies, both research orientated and treatment orientated, rather than on laboratory studies. Contributions are also welcomed from the fields of epidemiology, tumor pathology, radiobiology and radiation physics.

Journal follows editorial recommendations of International Committee of Medical Journal Editors (ICMJE) (available at http://www.icmje.org/recommendations/). Via Medica strongly recommends journal editors to adhere to the principles of Committee on Publication Ethics (COPE), particularly to deal with acts of ethical misconduct. For more information Authors, Readers and Editors may visit the COPE website: http://publicationethics.org/.

Authors statment All submitted manuscripts will be peer reviewed and the authors will be required to state that their paper has not been previously published or has been accepted for publication elsewhere, and has not simultaneously been submitted to another journal. An author statment must accompany each submitted manuscript and this letter must be signed by all authors and not only by the first author. In this letter any financial conflicts of interest must be specified. In addition, all sources of financial support for the study must be described. It is the responsibility of the main author of the paper to obtain written copyright permission for any material, text or illustrations, for which the copyright is owned by another person or persons or by an organization or by another journal.

Publication ethics and malpractice statement The Editor is responsible for everything published in the journal. The Editor takes all reasonable steps to ensure the quality of the material published. The Editor’s decision to accept or reject a paper for publication is based only on the paper’s importance, originality, clarity and the study’s relevance to the remit of the journal. The description of peer review process is published and clarified and the Editor is able and ready to justify any important deviation from the described process. The authors and peer reviewers’ identities are protected. The Editor provides guidance to authors and reviewers on everything that is expected of them. The Editor does not reverse a decision to accept a submission unless serious problems are identified. The relationship of the Editor to the publisher and owner is based firmly on the principle of editorial independence. The Editor makes decisions on which articles to publish based on quality and suitability for the journal and without interference from the journal owner/publisher.
The Editor can ensure that research material they publish conforms to internationally accepted ethical guidelines. The Editor is able to protect the confidentiality of individual information. The Editor has a duty to act if they suspect misconduct. The duty extends to both published and unpublished papers. The Editor should seek a response from those accused. If not satisfied with the response, the Editor should ask the relevant employers or some appropriate body to investigate. Editors should have systems for managing their own conflicts of interest as well as those of their staff, authors, reviewers and Editorial board members.

Human participants rights Any papers submitted which have required approval by local Ethics Committee, whether this be with regard to cancer patients within randomized or non-randomized clinical trials/studies or with regard to animal experimentation, should contain a statement to the effect that such approval has been obtained. In addition, written consent should be obtained for publication of any data or photograph, that might identify an individual patient. All procedures should be in accordance with the Helsinki Declaration.
