In order to assess the association of fibrosis with lung cancer, case control methodology was used to compare the type and severity of pneumoconiosis in the lungs of coal miners having primary lung cancer with that of coal miners not having lung cancer. The association of site of origin of lung tumor with coal workers' pneumoconiosis (CWP) was tested by comparing the lobar positions of tumors to the presence or absence of CWP within the lung cancer cases. Comparison of the type of CWP in coal miners with and without lung cancer showed that, overall, 84 percent of the lung cancer cases had either simple or complicated CWP as opposed to 66 percent in the controls. There was a statistically significant relationship between lung cancer and simple CWP and a slight, but nonsignificant, increase of severe CWP in the lung cancer cases.
