This dual-source descriptive study combined two independently analyzed components: a histopathology-based descriptive case series of diagnostic tumor submissions from dogs and cats, and a cross-sectional questionnaire survey of veterinarians practicing in Algeria. The first component characterized tumors reaching histopathological confirmation, whereas the second examined practitioner-reported tumor patterns, perceived diagnostic-resource availability, and self-reported preparedness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The histopathology-based case series comprised 86 tumor submissions from 81 animals accrued between March 2022 and March 2025. Mammary tumors were the largest category (43\/86; 50.0%), followed by cutaneous\/subcutaneous tumors (20\/86; 23.3%); 80 tumors (93.0%) were classified as malignant.<\/jats:p>\n                    <jats:p>Among 162 questionnaire responses collected between October 2024 and May 2025, 111 respondents selected \u201cdogs and cats\u201d as their main animal group. Mammary tumors were reported by 109 respondents (98.2%), cutaneous\/subcutaneous tumors by 79 (71.2%), and canine transmissible venereal tumor (CTVT) by 54 (48.6%); multiple categories could be reported. The most frequent self-reported preparedness rating was \u201cModerately prepared\u201d (52\/111; 46.8%), while 99 of 110 respondents with valid data (90.0%) rated diagnostic resources as either \u201cInsufficient\u201d or \u201cNot at all satisfactory.\u201d<\/jats:p>\n                    <jats:p>Mammary and cutaneous\/subcutaneous tumors ranked first and second in both sources, whereas the rankings of the remaining categories differed. Because the sources represented different populations, analytical units, denominators, and diagnostic pathways, the comparison was restricted to an exploratory descriptive assessment and was not interpreted as evidence of differences in population-level tumor occurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study provides an initial structured account of companion-animal tumor documentation in Algeria.

This study included two components: an anonymous questionnaire survey of veterinary practitioners and a descriptive analysis of histopathologically confirmed tumor submissions. For the questionnaire component, respondents were veterinarians who voluntarily completed an anonymous professional-practice survey. This component was conducted in accordance with the ethical principles of the Declaration of Helsinki. Before participation, respondents were informed of the objective of the survey, the voluntary nature of participation, and the confidentiality conditions. No names, contact details, personal identifiers, animal-owner identifiers, or identifiable clinical data were collected. Informed consent to participate was obtained from all questionnaire respondents through voluntary completion and submission of the questionnaire after this information had been provided. No separate signed consent form was collected because the questionnaire was anonymous and no identifiable personal data were collected. Formal ethics approval for the questionnaire component was not obtained because the survey was an anonymous, voluntary professional-practice questionnaire of veterinarians and did not involve patients, medical intervention, human biological material, human tissue, clinical procedures, sensitive personal data, or identifiable personal data. In Algeria, the national framework requiring authorization and ethics-committee review for biomedical research is set out in Law No. 18-11 of 2 July 2018 relating to health, published in the Official Journal of the Algerian Republic No. 46 on 29 July 2018, particularly Article 377 concerning biomedical research\/clinical studies on human beings and Articles 381\u2013383 concerning authorization and medical ethics committee review for clinical studies. Because the present questionnaire did not constitute a clinical study or biomedical research on human beings within this framework, formal ethics approval was deemed unnecessary according to national regulations. There is currently no institutional ethics committee or institutional review board at Universit\u00e9 de Constantine 1 Fr\u00e8res Mentouri \/ Institut des Sciences V\u00e9t\u00e9rinaires El-Khroub for anonymous professional-practice questionnaire studies of this type. For the histopathology-based diagnostic component, the study used anonymized routine veterinary diagnostic material from spontaneously occurring tumors submitted for histopathological diagnosis. This component involved no animal experimentation, no prospective intervention, no treatment allocation, no additional animal sampling for research purposes, no euthanasia, and no humane endpoint. It therefore did not constitute an animal experiment requiring formal animal ethics approval. There is currently no institutional animal ethics committee or institutional review board at Universit\u00e9 de Constantine 1 Fr\u00e8res Mentouri \/ Institut des Sciences V\u00e9t\u00e9rinaires El-Khroub for retrospective reviews of anonymized routine veterinary diagnostic material.","order":1,"name":"Ethics","label":"Ethics approval and consent to participate","group":{"name":"EthicsHeading","label":"Declarations"}},{"value":"Not applicable.","order":2,"name":"Ethics","label":"Consent for publication","group":{"name":"EthicsHeading","label":"Declarations"}},{"value":"The authors declare no competing interests.","order":3,"name":"Ethics","label":"Competing interests","group":{"name":"EthicsHeading","label":"Declarations"}}],"article-number":"612"}}
