Suicide among childhood cancer survivors in Slovenia

Suicide is one of the causes of late mortality among childhood cancer survivors. The aim of our study was to analyse the risk of suicide among childhood cancer survivors compared with that of the general population of Slovenia.

This retrospective study included patients with childhood cancer registered at the Cancer Registry of Slovenia between 1978-2008, with an observation period of 1978-2010. Childhood cancer patients and control subjects from the general population of Slovenia were matched by sex, year and age at the beginning of follow-up and time of follow-up in years. Data on the general population of Slovenia were obtained from the Statistical Office of the Republic of Slovenia.

A total of 1647 patients were recorded in the Cancer Registry as having cancer during childhood, with 3 patients committing suicide. All three were male. Their age at diagnosis of cancer was 12, 13 and 2 years old; their age at suicide was 19, 32 and 28 years old. The mechanism of death was asphyxiation in all three deaths. The calculation of the expected number of suicides in the group of individuals with childhood cancer from the general Slovene population revealed the number of 3.16 persons.

The comparison of the observed and expected probability showed that there was no statistically significant difference in the suicide rate between childhood cancer survivors and the general population of Slovenia.
