The pattern of presentation of carcinoma of the uterine cervix in East Anglia 1960 to 1975.

Changes in the pattern of presentation of carcinoma of the uterine cervix between 1960 and 1975 were studied using the records of 3193 patients registered with the East Anglian Cancer Registration Bureau. Between 1963 and 1968, an increased registration rate for invasive tumours was largely attributable to increased registrations of Stage I and II lesions in the 35 to 49 age group. After 1970 the registration rate for lesions of all stages in this age group declined. Over the same period the 50 to 64 age group showed a tendency for an increased proportion of registrations to be of Stage I or II lesions. There was little change in pattern in the over-65 age group. The possible relation of these changes to the introduction of a cervical cytology screening programme and the implications for future screening policies are discussed.
