Abstract

Aims and background: The paper examines the determinants associated with second primary occurrence in laryngeal cancer cases. Methods: A series of 220 incident male laryngeal cancer cases was interviewed 10 years ago within the framework of a population-based, case-control study. The occurrence of other primaries among these patients was assessed by means of the Lombardy cancer Registry, which covers their area of residence. The relationship between tobacco, alcohol, dietary factors and the risk of occurrence of new primaries was analyzed by means of a nested case-control study. Cases were defined as those subjects who developed a new primary, and controls as those without. Results: New primaries occurred among 36 subjects during an 8-year follow-up; 147 control cancer patients were matched for age and length of follow-up. A twofold risk increase was associated with the highest tobacco consumption, as registered at time of first primary; a weaker relationship, i.e. risk of 1.2 for the highest fertile, was seen for alcohol drinking. The occurrence of new primaries was also influenced by dietary habits. In particular, those who had a high intake of monosaturated fatty acids had a one-third lower risk of developing a new primary. Conclusions: Our results support the hypothesis that a healthy diet is protective among those who experience a laryngeal neoplasm and suggests that diet could be a potential preventive agent against the occurrence of new primaries among these patients.
