Title: Venous and Lung Thromboembolism in the Context of Lung Cancer: Clinical Manifestations, Risk Factors and Prognosis. Author: Maia R, Neves I, Morais A, Queiroga H. Journal: Acta Med Port; 2019 Oct 01; 32(10):647-653. PubMed ID: 31625877. Abstract: INTRODUCTION: The relationship between cancer and thromboembolic events has been known for a long time. Lung and venous thromboembolism are frequent complications of lung cancer and its treatment, being a great cause of morbidity and mortality. We pretend to establish the relationship between lung and venous thromboembolism and lung cancer, describe patient characteristics and analyze the impact in the survival and prognosis. MATERIAL AND METHODS: It was a retrospective study. All research subjects were selected from lung cancer patients with a newly diagnosed lung and venous thromboembolism event admitted to Hospital S. João, between January 2008 and December 2013 and were followed until December 2014. Statistical analysis was performed with SPSS. RESULTS: From the search, we obtained 113 patients. The majority was male, smokers or ex-smokers, and adenocarcinoma was the most frequent histologic type, being diagnosed mostly in advanced stages. We noticed that the median time between lung cancer diagnosis and lung venous thromboembolism was 2.9 months. In 24 patients (21.4%), the lung cancer diagnosis occurred after the lung and venous thromboembolism event and in 86 patients (76.8%), it occurred before the event. After a median follow up of 1.4 months, 107 (94.7%) patients died, 1 (0.9%) was lost to follow-up and 5 (4.4%) were still alive. The median survival rate was 1.5 months. DISCUSSION: The diagnosis of lung and venous thromboembolism in patients with lung cancer is associated with bad prognosis. It occurs most frequently in patients with advanced disease, in the first months after lung cancer diagnosis and after beginning chemotherapy. CONCLUSION: Disease progression is an independent predictor with negative impact in overall survival. Introdução: A relação entre as neoplasias e os eventos tromboembólicos é uma realidade já conhecida. O tromboembolismo pulmonar e venoso são complicações frequentes das neoplasias e do seu tratamento. Pretende-se estabelecer a relação entre o tromboembolismo pulmonar e venoso e a neoplasia pulmonar, descrever as suas características clínicas e analisar o seu impacto na sobrevida e prognóstico. Material e Métodos: Este estudo é retrospetivo. Foram selecionados doentes com neoplasia pulmonar, diagnosticados com tromboembolismo pulmonar e venoso no Hospital de S. João entre janeiro de 2008 e dezembro de 2013, e acompanhados até dezembro de 2014. A análise estatística foi realizada utilizando o SPSS. Resultados: Da pesquisa efetuada, foram obtidos 113 doentes. A maioria eram homens, fumadores ou ex-fumadores, e o adenocarcinoma foi o tipo histológico mais frequentemente encontrado, diagnosticado maioritariamente em estádios avançados. A mediana de tempo entre o diagnóstico de neoplasia pulmonar e tromboembolismo pulmonar e venoso foi de 2,9 meses. Em 24 doentes (21,4%), o diagnóstico de neoplasia pulmonar ocorreu depois do tromboembolismo pulmonar e venoso e em 86 doentes (76,8%) antes do evento. Após uma mediana de follow-up de 1,4 meses, 107 (94,7%) dos doentes faleceram, 1 (0,9%) deixou de ser seguido e 5 (4,4%) permaneceram vivos no fim do estudo. A mediana da taxa de sobrevivência foi de 1,5 meses. Discussão: O diagnóstico de tromboembolismo pulmonar e venoso nos doentes com neoplasia pulmonar está associado a mau prognóstico. Ocorre mais frequentemente em doentes com doença avançada, nos primeiros meses depois do diagnóstico e do início da quimioterapia. Conclusão: A progressão da doença demonstrarou ser preditor independente com impacto negativo na sobrevida global.[Abstract] [Full Text] [Related] [New Search]
