Resumo: | Background: Colorectal cancer has a high global mortality and tumor markers have emerged as diagnostic, management and prognostic indicators. New markers are being studied. Objective: To verify if there is a correlation between the immunohistochemical expression of ALCAM and ALDH1 proteins in colorectal adenocarcinoma tissue with epidemiological and clinicopathological characteristics, in particular their impact on disease progression and death. Method: Observational, single-center, analytical, retrospective study, through the investigation of patients undergoing surgical resection for colorectal cancer. 122 patients were evaluated. Regarding progression, it was shown that in individuals with positive ALCAM (n=40), 14/40 (35%) had progression, and for positive ALDH (n=54), 22/54 (40.7%). For death, the analysis of ALCAM positive (n=40), 24/40 (60%) died, and ALDH1 positive (n=54), 33/54 (61.1%). Conclusion: The immunohistochemical expression of ALCAM and ALDH1 markers was not associated with disease progression and death; it was also not possible to observe a correspondence relationship with the evaluated markers. |

Novos marcadores estão sendo estudados. Objetivo: Verificar se há correlação da expressão por imunoistoquímica das proteínas ALCAM e ALDH1 em tecido com adenocarcinoma colorretal com as características epidemiológicas e clinicopatológicas, em particular o seu impacto na progressão de doença e no óbito. Método: Estudo observacional, unicêntrico, analítico, retrospectivo, através da investigação de pacientes submetidos à ressecção cirúrgica por câncer colorretal. Foram avaliados 122 pacientes. Em relação a progressão, mostrou-se que nos indivíduos com ALCAM positiva (n=40), 14/40 (35%) tiveram progressão, e para ALDH positiva (n=54), 22/54 (40,7%). Para óbito, a análise da ALCAM positiva (n=40), 24/40 (60%) morreram, e ALDH1 positivo (n=54), 33/54 (61,1%). Conclusão: A expressão imunoistoquímica dos marcadores ALCAM e ALDH1 não apresentou associação com a progressão de doença e óbito; também não foi possível observar relação de correspondência com os marcadores avaliados.SciELO PreprintsSciELO PreprintsSciELO Preprints2022-06-01info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/420810.1590/SciELOPreprints.4208porhttps://preprints.scielo.org/index.php/scielo/article/view/4208/7966Copyright (c) 2022 Cecilia Neves de Vasconcelos, Carmen Australia Paredes Marcondes Ribas, Rodrigo Ketzer Krebs, Ana Maria Waaga-Gasser, Martin Gasser, Nicolau Gregori Czeczko, Osvaldo Malafaiahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessVasconcelos, Cecilia Neves deRibas, Carmen Australia Paredes MarcondesKrebs, Rodrigo KetzerWaaga-Gasser, Ana MariaGasser, MartinCzeczko, Nicolau GregoriMalafaia, Osvaldoreponame:SciELO Preprintsinstname:SciELOinstacron:SCI2022-05-31T20:15:53Zoai:ops.preprints.scielo.org:preprint/4208Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2022-05-31T20:15:53SciELO Preprints - SciELOfalse |
