Background: Golestan Province in north-eastern Iran has one of the highest incidence rates for esophageal squamous cell carcinoma (ESCC) worldwide. Earlier studies have reported higher incidence rates in the areas of Golestan which are mainly inhabited by individuals of the Turkmen ethnic group. However, it is not clear whether in those areas the incidence among Turkmens is higher in comparison to non-Turkmens. Some previous studies have suggested that environmental factors might play a more essential role in ESCC carcinogenesis in Golestan than a genetic background. If environmental factors instead of a genetic background are the major risk factors, therefore the prevalence of known environmental risk factors would not significantly differ among ESCC cases of different ethnic groups. To investigate the role of environmental factors versus genetic background by using the above concept, we have compared the prevalence of known risk factors for ESCC among Turkmen and non-Turkmen ESCC cases. Methods: Study participants were histopathologically proven ESCC cases from Golestan Province. They were recruited in the study from December 2003 to June 2007. The prevalence of the most important known risk factors for ESCC in Turkmen and non-Turkmen ESCC cases was compared using Chi-squared and Fisher's exact tests. Results: Of 300 ESCC cases recruited in the study, 171 (57.0%) and 129 (43.0%) cases were Turkmen and non-Turkmen, respectively. In the majority of the investigated risk factors which included tobacco, nass, and opium use, hot and extremely hot tea consumption, as well as decreased levels of education; there was no significant difference between Turkmen and nonTurkmen ESCC cases in the prevalence of exposure. Conclusion: Our findings support the suggestion that a substantial difference between Turkmens and non-Turkmens in terms of genetic susceptibility to ESCC is unlikely. Nevertheless, the moderate effect of genetic factors cannot be ruled out. Further studies to investigate potential environmental and genetic risk factors of ESCC in Golestan and the interaction between environmental and genetic factors are warranted.
