Ethical disclosures and conflicts of interest


Protection of people and animals
All studies that involve data, procedures, treatments, etc. in humans must have written authorization from an ethics committee of the participating institution, which must be attached to the manuscripts submitted on the platform, in addition to following the ethical guidelines of the World Medical Association and the Declaration of Helsinki, available at: http://www.wma.net. Authors must state in the section "Methods" that the procedures used in patients and controls have been carried out after obtaining an authorization by the ethics committee of their institution.

Confidentiality
Authors are responsible for following the protocols established by their respective health centers to access the data of the clinical files in order to carry out this type of scientific research, for which they must declare compliance with this requirement. The corresponding author has the obligation to guarantee that he is in possession of the written informed consent for the participation of each subject in the study. This document must be attached to the platform of the site. The authors should mention in the section "Methods" that the procedures performed on the study subjects were carried out after obtaining an informed consent.

Privacy
The corresponding author is responsible for ensuring the right to privacy of patients by protecting their identity both in the text of the article and in the images. Do not use names, initials or hospital medical record numbers (or any other type of data irrelevant to the investigation that could identify the patient) or in the text or in the photographs; unless such information is essential for scientific purposes. In such cases, it may be included in the article provided that the patient or his or her parent or legal guardian provides written informed consent for its publication.

Funding
Authors must declare any funding sources involved in the development of the research or the publication.

Authorship
Gaceta Mexicana de Oncología, GAMO (Mexican Journal of Oncology) follows the requirements established by the International Committee of Medical Journal Editors for its authorship. The list of authors should include only those who have contributed intellectually to the development of the manuscript; having helped in the collection of data or having participated in a technique, are not enough criteria to be listed as an author. In general, to appear as an author, the following requirements must be met:
- Participation in the conception and design, acquisition of data, analysis and interpretation of the study data that has resulted in the manuscript.
- Participation in the writing of the text and possible revisions thereof.
- Having approved the final version for publication.
- Having agreed to the accountability of all aspects of the study.
The corresponding author is responsible for ensuring that all co-authors meet the requirements for authorship. Each author agrees that the corresponding author will be responsible for submitting the manuscript to the journal. By submitting this manuscript, each of the authors indicates that they have had full access to all the data in this study and assume full and public responsibility for the integrity and accuracy of the data analysis. Once the manuscript is submitted, it will not be possible to make changes in the order and number of authors, so all issues related to authorship must be solved before sending the manuscript for the first time.

Conflicts of interest
There is a conflict of interest when the author had or has economic or personal relationships that could be considered as a cause of bias or influence the results of the study. The potential conflict of interest exists regardless of whether the authors consider that these relationships influence their scientific criteria or not. The authors will describe in the first page of the manuscript any financial or personal relationship that they had or have, at the time of writing or sending the manuscript, with people or institutions and that could give rise to a conflict of interest related to the manuscript that is submitted for publication. The editor in chief will be who judges if the conflict of interest is such. What is declared will be recorded in the journal.
