No local da inflamação estão presentes macrófagos e neutrófilos, além de citocinas como o fator de necrose tumoral-alfa (TNF-α) e o interferon-gama (IFN-γ). Este estudo visa avaliar a resposta inflamatória sérica em mulheres com lesões pré-invasoras e invasoras do colo uterino. Foram analisadas amostras de soro obtidas de mulheres sem evidência de doença (n=30 – grupo controle), com lesões pré invasoras do colo uterino (NIC) (n=30) e com carcinoma invasor de colo uterino (CCE) (n=30). O sangue das pacientes foi coletado, centrifugado e armazenado até análise laboratorial. A atividade das enzimas inflamatórias N-acetilglucosaminidase (NAG) e mieloperoxidase (MPO) foram obtidas por ensaio enzimático. Utilizou-se o método imunoenzimático de ELISA para obtenção dos níveis séricos do TNF-α e IFN-γ. As diferenças entre os grupos foram avaliadas pelo teste do qui-quadrado, Kruskal-Wallis ou Mann Whitney. A correlação entre os grupos foi realizada pelo teste Kendall's Tau. As diferenças com valor de p<0,05 foram consideradas significativas. No grupo de pacientes com lesões pré- invasoras do colo uterino, duas mulheres apresentavam NIC I (6,7%), oito pacientes NIC II (26,7%) e 20 casos apresentavam NIC III (66,7%). O estadiamento (FIGO) das pacientes com CCE invasor foi IA2 em três casos (10,0%), IB1 em 19 (63,3%), IB2 em dois (6,7%) e IIA em seis (20,0%) mulheres pertencentes a esse grupo. As atividades das enzimas NAG, MPO e níveis de TNF-α foram maiores no grupo de mulheres com NIC, quando comparado com o grupo com CCE. Os níveis de IFN-γ foram menores no grupo de mulheres com NIC, quando comparado com o grupo com CCE. Não houve uma associação significativa entre o grau do NIC e o estadiamento do CCE invasor... === Introduction: The inflammatory response is an active process in cervical cancer and may act in the progression and/or regression of the lesion. At the site of inflammation cells are present, among the most important macrophages and neutrophils and some cytokines such as TNF- and IFN- . This study aims to evaluate the inflammatory response levels in women with pre-invasive lesions and invasive cervical cancer. Methods: Were analyzed serum samples obtained from women without evidence of disease (n = 30 - control group), with pre-invasive lesions of the cervix (n = 30) and with carcinoma of the cervix (n = 30). The activity of inflammatory enzymes Nacetylglucosaminidase (NAG) and myeloperoxidase (MPO) were obtained by enzymatic assay. We used the ELISA assay method for obtaining serum levels of TNF- and IFN- . The blood of the patients was collected, centrifuged and stored until laboratory analysis. Differences between groups were evaluated by chi-square, Kruskal-Wallis and Mann Whitney. The correlation between the groups was performed using Kendall's Tau. Differences with p <0.05 were considered significant. Results: The women age ranged from 30 to 79 years. In the group of patients with preinvasive lesions of the cervix, two had CIN I (6.7%), eight patients with CIN II (26.7%) and 20 cases had CIN III (66.7%). Staging (FIGO) of patients with SCC was IA2 in three cases (10.0%), IB1 in 19 (63.3%), IB2 in two (6.7%) and IIA in six women (20.0%). The activities of enzymes NAG, and MPO and the levels of TNF- were higher in women with CIN compared with the group with SCC. The levels of IFN- were lower in the group of women with CIN compared with the group with SCC. There was not a significant association between the degree of the CIN and the staging of the SCC of the cervix with inflammation assessed by the levels of inflammatory markers used...
