Abstract
Background
Mortality data have clearly highlighted the province of Ferrara as an area with a particular distribution of tumors strictly related with environmental factors.
Methods
The project of a tumor registry has been planned for a better description of cancer incidence and for a deeper insight into etiologic factors, considering the typical features of the province from geographic and occupational points of view.
Results
This study presents the registration results of the first 2 years, in order to verify the quality level of data recruitment and to confirm that observed in previous studies. The population covered by the registry was 151,968 males and 165,835 females, with high representation of the elderly. In this period 2,087 tumors in men and 1,778 in women were observed. Lung cancer reaches one of the highest levels in Italy, according to that observed in Lombardy and Veneto regions and the northern Adriatic coast. Incidence and mortality are, however, significantly higher than in other Emilia-Romagna areas, as pointed out by the registries of Parma, Modena and Forlì. Colon cancer also presents high frequencies in comparison with neighboring areas, whereas non-Hodgkin lymphomas reach the highest level in Italy. Gastric tumors, although well represented in males and females, show lower levels than the high-risk neighboring Romagna region. In women, a low incidence of cervix uteri tumors and high levels of breast cancer have also been observed.
Conclusions
The distribution of such neoplasms and the differences observed among neighboring areas deserve further analytical studies, with the aim of a better reading of cancer onset and diffusion. The quality of data obtained (about 70% of histocytologic confirmations, and 5% of “final” death-certificate-only cases), appears to reach satisfying levels, considering the starting phase of the registry.
