Los pacientes con c\u00e1ncer de cabeza y cuello presentan un riesgo elevado de desarrollar tumores primarios-secundarios en el es\u00f3fago, lo que repercute negativamente en el pron\u00f3stico. La detecci\u00f3n temprana de estas lesiones puede mejorar de manera significativa la supervivencia.\nObjetivo. Determinar la prevalencia de carcinoma epidermoide de es\u00f3fago en pacientes con c\u00e1ncer de cabeza y cuello, y describir sus caracter\u00edsticas epidemiol\u00f3gicas.\nMateriales y m\u00e9todos. Se realiz\u00f3 un estudio retrospectivo sobre la base de una cohorte de pacientes con diagn\u00f3stico actual o previo de c\u00e1ncer de cabeza y cuello sometidos a esofagogastroduodenoscopia para pesquisa de tumores primarios-secundarios durante 2022, en un centro de referencia de S\u00e3o Paulo, Brasil.\n Resultados. De los 177 pacientes evaluados, 165 cumplieron los criterios de inclusi\u00f3n. Se detect\u00f3 carcinoma epidermoide de es\u00f3fago en el 4,84% (IC 95%: 2,1\u20139,2) de los pacientes evaluados (8 de 165 casos), y en la mitad de ellos se diagnostic\u00f3 en estadios avanzados. Predominaron los hombres (79%), con edad media de 65 a\u00f1os, fumadores y con tumor primario en la orofaringe. Las lesiones esof\u00e1gicas de 7 mil\u00edmetros o m\u00e1s se asociaron significativamente con neoplasia.\n Conclusi\u00f3n. La prevalencia de tumores esof\u00e1gicos primarios-secundarios en pacientes con c\u00e1ncer de cabeza y cuello es relevante. Los varones de mayor edad, fumadores y con antecedente de tumor orofar\u00edngeo representan el grupo de mayor riesgo. En este perfil, las lesiones endosc\u00f3picas de 7 mil\u00edmetros o m\u00e1s deben considerarse un marcador de alto riesgo de neoplasia, lo que justifica la implementaci\u00f3n de programas de pesquisa dirigidos a poblaciones vulnerables.<\/jats:p>","DOI":"10.52787\/agl.v55i4.534","type":"journal-article","created":{"date-parts":[[2025,12,23]],"date-time":"2025-12-23T19:15:26Z","timestamp":1766517326000},"page":"379-385","source":"Crossref","is-referenced-by-count":0,"title":["Prevalencia de carcinoma epidermoide de es\u00f3fago en pacientes con c\u00e1ncer de cabeza y cuello: estudio unic\u00e9ntrico"],"prefix":"10.52787","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0316-2617","authenticated-orcid":false,"given":"Ana Victoria","family":"Martins Lima","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7276-1937","authenticated-orcid":false,"given":"Fernanda","family":"Carvalho Franco","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6327-1367","authenticated-orcid":false,"given":"Cesar Saul","family":"Quevedo Penaloza","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5404-7969","authenticated-orcid":false,"given":"Diego","family":"Cadena Agirre","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafael","family":"Sartori Balbinot","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Regina","family":"Rie Imada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio","family":"Marioni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0629-8050","authenticated-orcid":false,"given":"Renata","family":"Nobre Moura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gustavo","family":"Andrade de Paulo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriana","family":"Vaz Safatle-Ribeiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louise","family":"Menezes da Cunha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8714-2615","authenticated-orcid":false,"given":"F\u00e1bio","family":"Gon\u00e7alves Ferreira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"30608","published-online":{"date-parts":[[2025,12,23]]},"container-title":["Acta Gastroenterol\u00f3gica Latinoamericana"],"original-title":[],"link":[{"URL":"https:\/\/actaojs.org.ar\/ojs\/index.php\/acta\/article\/download\/534\/923","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/actaojs.org.ar\/ojs\/index.php\/acta\/article\/download\/534\/937","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/actaojs.org.ar\/ojs\/index.php\/acta\/article\/download\/534\/937","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,23]],"date-time":"2025-12-23T19:15:26Z","timestamp":1766517326000},"score":1,"resource":{"primary":{"URL":"https:\/\/actaojs.org.ar\/ojs\/index.php\/acta\/article\/view\/534"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,23]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2025,12,23]]}},"URL":"https:\/\/doi.org\/10.52787\/agl.v55i4.534","relation":{},"ISSN":["2469-1119"],"issn-type":[{"value":"2469-1119","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12,23]]}}}
