The Rhein-Neckar-Larynx Study is a population-based case-control study 1:3 frequency matched by age and sex on laryngeal cancer in South-West Germany with 257 cases, histologically confirmed and diagnosed between 1.5.1998 and 31.12.2000 and 769 population controls. Information about occupational exposures, lifestyle factors and socio demographic background were obtained with face-to-face interviews using a detailed standardized questionnaire.

 

As expected, highest risks on laryngeal cancer were found for smoking and alcohol consumption (Ramroth et al. 2004). For occupational exposures we found higher risks for polycyclic aromatic hydrocarbons (Becher et al 2005), cement dust (Dietz et al. 2004) and wood dust (Ramroth et al. submitted), but no association for asbestos.

 

We did not find a risk modifying effect of genetic polymorphisms in enzymes involved in ethanol and tobacco carcinogen metabolism (Risch et al. 2002), but our results suggest that a reduced capacity of somatic cells to synthesize poly(ADP-ribose) (Rajaee-Behbahani et al. 2002) might be associated with an increased risk for laryngeal cancer. Further analyses related to alcohol, and active and passive smoking have additionally been performed.
