Cervical Cancer in Women with Inflammatory Pap Smears

摘要

In spite of preventive measures such as Papanicolaou cervical cytological analysis and, more recently, vaccination against HPV infection, cancer of the uterine cervix continues to be one of the most frequent causes of mortality among women worldwide, particularly in developing countries. In this prospective study, sixty patients with inflammatory Pap smears had a colposcopy with directed biopsies. The average age of our patients was 42 years. Results showed that colposcopy is normal in 10% of women. It showed normal transformations, ectropion, a colpotis and polyp at 8.33%, 21.66%, 13.33% and 5% respectively. It was able to detect changes with Grade I atypical transformations (28.33%), and Grade II atypical transformations in 13.33% of cases. The biopsies were objectified dysplasia and carcinoma in 24.13% of cases with carcinoma in situ, micro invasive squamous cell carcinoma and invasive carcinoma glandular. Moreover, we detected HPV-specific antibodies in sera of these patients. Results showed that six patients (10%) showed a positive reactivity to at least one of the HPV-16 or HPV-18 antigens and sera showed different reactivity to the different antigens with the following percentages: 5%, 3%, 2%, 3% and 3% for L1 HPV-16, E6 HPV-16, E7 HPV-16, E6 HPV-18 and E7 HPV-18 respectively. Among patients having positive antibody response, 83.33% were cases of dysplasia and carcinoma. We concluded that the Pap smear, examination of key screening for cervical cancer, is a screening test without diagnostic value and more specifically any inflammatory Pap smear should be considered a positive test and led to further investigations. Moreover, colposcopy is an exam that is performed on an outpatient basis;it allows a detailed study of the cervix and reduces the negative rate of cytology. In addition, early detection of HPV antibodies could help the follow-up of patients.
