Hyaluronan (HA) shows promise for detecting cancerous change in pleural effusion and
urine. However, there is uncertainty about the localization of HA in tumor tissue and
its relationship with different histological types and other components of the
extracellular matrix, such as angiogenesis. We evaluated the association between HA
and degree of malignancy through expression in lung tumor tissue and sputum. Tumoral
tissue had significantly increased HA compared to normal tissue. Strong HA staining
intensity associated with cancer cells was significant in squamous cell carcinoma
compared to adenocarcinoma and large cell carcinoma. A significant direct association
was found between tumors with a high percentage of HA and MVD (microvessel density)
in tumoral stroma. Similarly significant was the direct association between N1 tumors
and high levels of HA in cancer cells. Cox multivariate analysis showed significant
association between better survival and low HA. HA increased in sputum from lung
cancer patients compared to cancer-free and healthy volunteers and a significant
correlation was found between HA in sputum and HA in cancer tissue. Localization of
HA in tumor tissue was related to malignancy and reflected in sputum, making this an
emerging factor for an important diagnostic procedure in patients suspected to have
lung cancer. Further study in additional patients in a randomized prospective trial
is required to finalize these results and to validate our quantitative assessment of
HA, as well as to couple it to gold standard sputum cytology.
Objetivo: Mapear a produção científica sobre as repercussões emocionais e os processos adaptativos vividos por pessoas com estomias. Método: Revisão integrativa com coleta de dados nos meses de julho a agosto, nas bases de dados dos sítios da Biblioteca Virtual em Saúde, Literatura Latino Americana e do Caribe em Ciências da Saúde, na Literatura Internacional em ciência da Saúde e na Base de Dados de Enfermagem, com os escritores “emoções”, “sentimentos”, “estomias”, “pessoas” e “cuidados de Enfermagem”. Utilizaram-se artigos publicados entre os anos 2013 a 2017. Resultados: Com análise temática emergiram três categorias: “repercussões emocionais e as dificuldades no processo de adaptação da pessoa com estomia”, “medidas de enfrentamento no processo de reabilitação da pessoa com estomia” e “o cuidado de enfermagem: apoio profissional relacionado ao autocuidado”. Conclusão: A pessoa com estomia vivenciou momentos de depressão, tristeza, isolamento social e afastamento da atividade laboral. O enfermeiro em conjunto com a equipe multidisciplinar precisa desenvolver além de planos de cuidados e orientações, acompanhamento psicológico e apoio emocional para que a pessoa com estomia tenha uma melhor adaptação.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
