Cervical cancer is a preventable public health concern ranking second among women’s cancer in Cameroon. Human papilloma virus (HPV) is the main causative agent with Chlamydia trachomatis being suggested as the co-factor. Our objective was to characterize high risk (hr) HPV types and to detect Chlamydia trachomatis antibodies among Cameroonian women with and without cervical cancer. Methods: This unmatched case-control study enrolled 100 cases with cervical cancer and 200 controls with normal cytology aged 25- 65 years in four reference hospitals in Douala and Yaoundé (Cameroon). Consented participants filled a structured questionnaire and data on socio-demographic characteristics collected. Chlamydia trachomatis antibodies were detected by the Enzyme Linked Immuno-Sorbent Assay technique (ELISA) and hr HPV- DNA by PCR technique. Descriptive statistics was conducted to provide frequencies and percentages and the logistic regression analysis to assess the association between categorical data. p < 0.05 was considered significant. Results: Our data showed 39 (39.0%) cases aged 39-52 years compared to 96 (48.0%) controls aged 25-38 years (p=0.001). We found 82 (82.0%) cases compared to 131 (65.5%) controls with hr HPV infections. HPV 16 was most prevalent being found in 29 (29.0%) cases compared to 69 (34.5%) controls. Chlamydia trachomatis IgG / hr HPV co-infections were detected in 20 (20.0%) cases compared to 33 (16.5%) controls but with no significant association with cervical cancer (aOR=1.87; 95%CI: 0.58-5.97; p=0.293). Chlamydia trachomatis IgM (aOR=3.50; 95%CI: 1.16-10.49; p=0.025) was significantly associated with cervical cancer. Conclusion: Hr HPV- DNA was high in cases than in controls. Chlamydia trachomatis single infection and Chlamydia trachomatis/hr HPV co-infections were not significantly associated to precancerous lesions thus, necessitating further investigations.
