title: Suicide mortality is decreasing among cancer patients in Central Italy.
abstract: The objective of this study was to discover whether suicide mortality among patients diagnosed with cancer during the period 1985-1999 had decreased with calendar time in comparison to the rate in the general population. 90?197 cancer patients resident in Tuscany, Central Italy and incident during the period 1985-1999 were followed up for life status to 31 December 2000. The mortality codes for suicide were considered (E950-E959). Time trends for suicide rates were assessed by using Kernel smoothing estimators, standardised mortality ratios and Poisson analysis of the observed/expected ratios. The standardised mortality ratios were 324, 224, and 185 for cancer patients diagnosed during the periods 1985-1989, 1990-1994, and 1995-1999, respectively. Tests for linear trends were borderline significant (P=0.053). Suicide mortality among cancer patients in central Italy had decreased with calendar time relative to the suicide trend in the general population. Improved treatment options and better communication of diagnosis are possible explanations of this finding.
