ESTUDO DA INFLUÊNCIA DO MATERIAL PARTICULADO FINO (PM 2,5) NO DESENVOLVIMENTO DE NEOPLASIAS PULMONARES: UMA REVISÃO INTEGRATIVA

Resumo

A poluição atmosférica, especialmente pelo material particulado fino (PM2,5), representa um risco relevante à saúde pública, estando diretamente associada ao aumento da incidência e mortalidade por câncer de pulmão. Este estudo, desenvolvido por meio de revisão bibliográfica integrativa, teve como objetivo analisar a influência do PM2,5 no desenvolvimento de neoplasias pulmonares. Foram consultadas as bases de dados PubMed, BVS e SciELO, considerando publicações entre 2014 e março de 2025, nos idiomas português e inglês. Aplicaram-se critérios de inclusão e exclusão, resultando na seleção de 10 artigos originais. Os dados analisados evidenciam que a exposição crônica ao PM2,5 está relacionada ao aumento do risco de câncer de pulmão, mesmo em concentrações inferiores aos limites recomendados por órgãos internacionais. Populações próximas a zonas industriais, portos e regiões afetadas por incêndios florestais apresentam risco significativamente maior. Estudos moleculares demonstram que o PM2,5 pode induzir alterações genéticas, ativar vias oncogênicas, como Wnt/β-catenina, e promover metástases, envolvendo estresse oxidativo, inflamação crônica e falhas no reparo do DNA. Conclui-se que o PM2,5 atua como fator determinante na carcinogênese pulmonar, tanto na indução quanto na progressão tumoral. Seus efeitos são agravados pela exposição prolongada, mesmo em níveis considerados seguros. Tais achados reforçam a urgência de políticas públicas rigorosas para o controle da poluição atmosférica.
