A study of cervical cancer in Ethiopian women.

In common with many African countries, Ethiopia has a very limited cytological service, smears are only taken in a hospital or clinic setting and until very recently most had to be sent abroad for analysis. We describe the results of a clinical and cytological investigation of 2111 women attending hospitals and clinics in Addis Ababa: 33 invasive or microinvasive cancers and 10 dysplasias (CIN) were detected. The prevalence of invasive cervical cancer in that population was 15.6/1000. Risk factors were shown to be age over 35 (especially over 50), parity over six (especially more than 10), very low income or subsistence economy, particularly in those from the rural areas, and prostitution. Less significant factors, possibly related to age, were sexual activity of more than 20 years and first coitus before the age of 15; and more than five sexual partners. Most (66%) of women with invasive cancer were at stage 3 or 4.
