Increasing trends of cervical adenocarcinoma incidence in Central Italy despite Extensive Screening Programme, 1985-2000.
Incidence rates of adenocarcinoma of the uterine cervix have been reported to be increasing in several countries, but not in Italy. The aim of the present study was to analyse trends in cervical cancer incidence by histological type in two districts of Central Italy (Florence and Prato), covered by the Tuscany Cancer Registry (RTT), where cytological screening had been available since the 1970s. Incident cervical cancers during 1985-2000 were 1012. Estimated Annual Percent Change (EAPC) by age-groups and histological type were computed. Incidence increased for adenocarcinoma (EAPC = +5.7%; 95% confidence interval (CI)+2.8; +8.6); whereas, it decreased for squamous cancer (EAPC = -1.9%; 95% CI-3.8; 0) and for other or not specified types (EAPC = -4.4%; 95% CI-10.0; +1.5). Adenocarcinoma increased significantly among younger women (<55 years) but not among older ones, whereas squamous cell cancer decreased among older women only. The burden of cervical cancers might increase in the future if no specific preventive strategies for adenocarcinoma are implemented.
