    For use in an investigation of the temporal development of the incidence of cancer of the lung among nonsmokers, a pilot investigation was undertaken to assess the value of information about smoking habits in hospital case-histories. The names of 40 individuals with cancer of the lung during the period 1952-1954 (20 men and 20 women) and 40 individuals from the period 1974-1976 (20 men and 20 women) were drawn from the Danish Cancer Register. Hospital case-histories were obtained and in 29 out of 36 case-histories (81%) during the period 1974-1976, information was available about smoking habits. Only five out of 19 case-histories (26%) provided similar information for the period 1952-1954. Whereas satisfactory information about habits was available for the period 1974-1976, information on this subject was insufficient concerning the previous period. The historical investigation of the incidence of cancer of the lung was carried out, but the value of the case-histories for epidemiological investigation of even such simple conditions is of doubtful value. For the period 1974-1976, the incidence of cancer of the lung was found in this investigation also to be higher among smokers than among non-smokers.
