Instructions for authors

1. General

1.1 Conditions of acceptance

Submission of a manuscript implies that the work has not been published and is not submitted for publication anywhere else. Publication must be approved by all authors. Authors should accept publication fees. For ethics in publishing consult COPE.

Authors are invited to comply with the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals”, which were established and made available by the International Committee of Medical Journal Editors (ICMJE) at: http://www.icmje.org/recommendations/.

1.2 Authorship

The ICMJE recommends that all those designated as authors meet all of the criteria they describe. The list of criteria is available at http://www.icmje.org/recommendations/browse/roles-and-responsibilities/. Those contributors who do not meet all of the criteria shall be acknowledged.

1.3 Conflict of interest

Authors must disclose whether or not they have a financial relationship with the organization that sponsored the research. They should also state that they have full control of all primary data and that they agree to allow the journal to review their data if requested.

Therefore the manuscript must be accompanied by the "Conflicts of Interest Disclosure Form" at the initial submission.

Any additional conflict of interest, on personal or any other level must also be disclosed.

1.4 Publication Ethics and protection of research participants

All laws and regulations should be strictly followed. Authors are requested to indicate ethical declarations issued by their institution and concerning their research, including permit numbers, in the Material and Methods section. Authors are requested to fully comply with the ICMJE recommendations in this respect, particularly with the patient’s right to privacy, as well as the necessity to have the patient’s written consent.

1.5 Reporting guidelines and clinical trial registration

Depending on the study design, reporting guidelines such as CONSORT, STROBE, PRISMA, STARD should be followed. For more information about these guidelines authors should visit the websites of the EQUATOR network or the corresponding sources at the NLM website. The policy for clinical trial registration by the ICMJE is given in their recommendations. These should be followed by the authors in this journal.

1.6 Publication fees will be covered

Open Access journals have no income from institutional or membership subscriptions. The costs for the publication of these journals require the payment of article processing charges (APCs) or financial support.

For the journal Visualized Cancer Medicine, Zhongke Digital Publishing and Media Co., Ltd. (ZDP&M) will support the full publication costs of the articles. The authors have nothing to pay the first years before the journal gets indexed.

1.7 Open access

All articles published in Visualized Cancer Medicine are made freely and permanently accessible online immediately upon publication, without subscription charges or registration barriers. Articles are available from the website of the journal (https://vcm.edpsciences.org/), from PubMed Central as soon as the indexation of the journal is effective and from Europe PubMed Central, in various formats. Authors are the copyright holders of their articles. All articles bear the following mention: This is an Open Access article distributed under the terms of the Creative Commons Attribution License 4.0, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

1.8 Manuscript compliance with the instructions for authors

Authors are invited to carefully read the below instructions. Articles not compliant with these instructions will be immediately sent back to the author. In order to avoid these additional delays in the publication of their articles, authors should know that their articles will enter the peer review process only if they are compliant after re-submission.

A frequent reason of immediate rejection is plagiarism. Using the Similarity Check tool for the text, allows to detect even minimal plagiarism. Thus authors are invited to read the ethical standards and apply the given indications in order to avoid this sanction.

1.9 Data sharing policy

Authors may be invited to share with the peer reviewers during the article evaluation process in a confidential manner the data on which the research is based. Further, as long as the publication of data is not in opposition with patients’ privacy, authors are invited to upload supplemental datasets related to their research to an online repository. Doing so makes it available for both human and machine reading in order to further aid the acceleration of scientific discovery.

Authors are invited to prepare and deposit their data according to the FAIR data principles. FAIR stands for Findable, Accessible, Interoperable and Re-usable. The principles are available here. To summarize this, the dataset should be findable through a complete set of metadata, including a license for re-use and a data identifier (DOI or other). The dataset is accessible when access is open. Interoperable means that the data can be used and combined with other datasets in a format that is sufficiently widely distributed. Re-usability is achieved when the dataset is deposited with a corresponding Creative Commons open license and is downloadable. Furthermore, re-usability implies that parameters describing how this dataset has been collected needs to be disclosed. Machine and experimental conditions must be documented.

1.10 Scientific Integrity

We hold scientific integrity as the top priority in any consideration of publication. Therefore, our authors are strongly suggested to upload their raw data onto Research Data Deposit (RDD) for further verification in case our readers have any doubt on the scientific integrity of the studied project. Please use this link for uploading your raw data onto RDD: http://www.researchdata.org.cn

2. Types of papers

Eleven types of publications are considered:

Citation of unpublished papers and grey literature should generally be avoided. Software cited in the Material and Methods should have a citation. Papers may be cited as “in press” only when they have been accepted for publication (in this case, include the DOI).

4. Tables

Tables (numbered as Table 1, Table 2, etc.) should be presented as one per page. Avoid complex formatting and use the basic Table format in Word or Excel.

5. Figures

5.1 Figure numbers and legends

Figures should be numbered as Figure 1, Figure 2, etc. They are referred to in the text as Figure 1, Figure 2, etc. Legends are grouped on a separate page.

5.2 Technical information

All figures are published free of charge (i.e. they are included in the publication fee), including color photographs and diagrams. However, only photographs of scientific interest and pertaining to the subject of the article should be included. Color illustrations, especially diagrams, should be understandable even, if they are printed as grey levels.

Figures should be prepared to be of good quality both when they are viewed onscreen as HTML and when the PDF is printed. Figures may be arranged as “plates”, but keep in mind that PDFs are prepared to be printed on A4 pages.

The electronic submission system will accept PNG (preferred), TIFF (with compression), and EPS files, with appropriate resolution (300 dpi for colour photographs, 600 dpi for halftone work, 1200 dpi for line work). JPG format is not recommended – PNG is preferred.

Manuscripts with figures of insufficient technical quality will be immediately sent back for revision by the editorial team and will not begin the review process before correct files are uploaded.

6. Videos

Videos should be numbered as Video 1, Video 2, etc. They are referred to in the text as Video 1, Video 2, etc. Legends are grouped on a separate page.

7. Supplementary Online material

Online material may include data too long to be included in the manuscript, additional illustrations and movies. Online material is subjected to strict refereeing. Formats accepted are: PDF, graphic formats for supplementary figures MPEG for videos. Files should preferably be less than 20 Mb.

8. Mathematics, statistics and significant figures

Write mathematical equations as simply as possible. Statistical software should be clearly indicated and cited.

Figures should be indicated with a reasonable number of digits, coherent with the significance of the result. This is especially important for the abstract.

9. References

Authors are encouraged to use a reference manager software. The below given format of the references is mandatory, authors are invited to strictly follow these guidelines.

Authors should provide direct references to original research sources whenever possible. References should not be used by authors, editors, or peer reviewers to promote self-interests. Authors should avoid citing articles in predatory or pseudo-journals.

Authors are responsible for checking that none of the references cite retracted articles except in the context of referring to the retraction. Authors can identify retracted articles in MEDLINE by searching in the PubMed's list of retracted publications.

9.1 References in the text

References are numbered as [1], [2,3,7] or [5–9]. This allows copious lists of references without lengthening the text itself. The use of numbered references does not mean that author names and dates of cited papers are prohibited in the text, but this should be used only if necessary.

Example: Many studies [1-9] have addressed … (no special need to indicate authors here). In 2013, Smith [10] claimed that … but Dupont [11,12] later demonstrated that… (names of authors and dates are useful here).

9.2 Presentation of references

References are numbered and sorted in the order of appearance in the text. Words in titles are not capitalised. No journal name begins with “The”.

All articles must be referenced in accordance with the Vancouver style. This style follows rules established by the International Committee of Medical Journal Editors, now maintained by the U.S. National Library of Medicine. It is also known as Uniform Requirements for Manuscripts submitted to Biomedical Journals.

The common structure of each reference follows always the below example:
