title: [Lung cancer risk in shoe manufacturing].
abstract: OBJECTIVE
  Workers in shoe manufacturing have been reported to be at a greater relative risk for bronchogenic carcinoma. Given the implications for our practice setting, we carried out a study to a) clarify whether working in shoe manufacturing is a risk factor for lung cancer and b) detect histological differences between lung cancers in shoe manufacturers and in other lung cancer patients.
  
  
  METHODS
  This case-control study compared all lung cancer patients diagnosed in Hospital Elda, Alicante, Spain, between January 1994 and December 1999, with a control group composed of patients admitted to the same hospital for accidental fractures. Information on occupational history and tobacco dependency was collected from all patients by telephone questionnaire.
  
  
  RESULTS
  One hundred and ninety-one case patients and 192 control patients were included in the study; 52 of the cases (27.2%) and 48 controls (25%) worked in shoe manufacturing. No statistically significant differences were found between the 2 groups, not even when we limited the cases and controls to only those who had worked more than 30 years in shoe manufacturing or when we analyzed only subjects who had had especially high risk occupations. No differences in tumor histology were found between cancer patients who worked in shoe manufacture and those who did not.
  
  
  CONCLUSIONS
  Working in shoe manufacturing has not proven to be a risk factor for bronchogenic carcinoma.
