title: [An epidemiological investigation on lung cancer and other tumours among coal workers with pneumoconiosis].
abstract: A retrospective cohort study was made on lung cancer and all tumours among coal workers with pneumoconiosis in the Haibowan Mining Bureau. Results indicated that the mortality of lung cancer among workers with pneumoconiosis was distinctly higher than that among the local population (P < 0.005, RR = 56.1, AR = 225.2, SMR = 8.07, P < 0.01). The mortality of all tumours among staffs and workers in the Haibowan Mining Bureau was 599.4 per one hundred thousand, but only 62.5 among the local population (P < 0.005). It is suggested that lung cancer in workers exposed to coal dust for more than 18 years should be regarded as occupational cancer.
