[Decrease of frequency of male lung cancer in Umbria region. 1978-1982 and 1994-1999]

In Umbria, region of Central Italy, lung cancer is the leading cause of death due to cancer in males. The aim of this work is to highlight decrease of mortality from lung cancer in males in Umbria, in the last 20 years and to describe relationship among incidence, mortality and survival of this cancer. The incidence data derived from an ad hoc survey carried out over the period 1978-1982 and for 1994-1999 from the Umbrian Population Cancer Registry (RTUP). The mortality data were derived from official publications of the Italian Central Institute for Statistics (ISTAT) and covered the entire period 1978-1999. Estimated annual percent change (EAPC) was calculated by joinpoint regression analysis. Decrease of mortality from male lung cancer in Umbria began in the 1990-ies due to reduced quantity of tar in cigarettes, decreasing consumption of tobacco and increasing of survival derived from the quality and the effectiveness of the oncological health care system.
