Abstract: Purpose of Investigation: Epithelial ovarian cancer (EOC) is the leading cause of death from gynaecological malignancy in the UK. The pathogenesis of this disease is poorly understood. Our hypothesis was that chlamydial infection might play a role in the pathogenesis of EOC.<br />Methods: 122 serum samples of patients undergoing surgery for benign or malignant gynaecological conditions were analysed. There was a total of 41 patients with EOC (33.6%), 27 with benign cystadenomas (22.1%) and 54 with normal ovaries (44.3%).<br />Results: There was a higher incidence of IgA seropositivity and lower incidence of IgG seropositivity in the EOC group compared with the other groups; however, this was not statistically significant. There was no statistical difference in the serum IgM antibodies to chlamydia in the three different groups.<br />Conclusion: Although chronic infection and persistent inflammation may contribute to the pathogenesis of EOC, and chlamydia is a common genital tract pathogen, our study did not find an association between chlamydia and EOC.
