Chlamydia trachomatis is the most frequent bacterial pathogen causing sexually transmitted diseases worldwide. Many studies emphasize that chlamydial infections may play role as a cofactor in cervical cancers caused by high risk human papillomavirus types. The aim of this study was to investigate the presence of antibodies specific for C.trachomatis in patients with cervical cancer in order to detect the frequency of chlamydial infections. A total of 77 patients diagnosed as cervical cancer who have undergone surgery and on treatment at Oncology Institute of Istanbul Faculty of Medicine were included in the study, together with 20 healthy women as the control group. Serum samples obtained from patient and control groups were investigated by a commercial microimmunofluorescence kit (Orgenium Laboratories, Finland) for the detection of C. trachomatis IgG, IgA and IgM antibodies. All of the control subjects (mean age: 30.25 +/- 6.4 years) were found seronegative, however the seropositivity rate detected in patients with cervical cancer was 9.1% (7/77). Serological data were interpreted as previous infections in four patients with single IgG positivity (titers: 1/16 in three and 1/32 in one patient), acute infections in two patients with IgG + IgM positivity (titers: IgG 1/64 and IgM 1/64 for both patients), and chronic infection in one patient with IgG + IgA positivity (titers: IgG 1/128 and IgA 1/20). The mean age of seven seropositive patients was 53.88 +/- 12.1 years, and three of them had antibodies against FGK, three against BDE and one against CHIJ serogroups of C.trachomatis. None of the cases had the history of sexually transmitted disease. No statistically significance was found between patient and control groups regarding C.trachomatis IgG, IgA and IgM seropositivity (for IgG; p = 0.339, for IgA; p = 1.000, for IgM; p = 1.000). However, it was thought that the statistical evaluations may not be conclusive due to the small number of study groups. In conclusion further studies with large numbers of cases are needed to understand the role of chlamydia infections in the development of cervical cancer.
