A study to obtain information on the relation between tuberculosis and carcinoma ofthe lung was carried out in 24 hospitals in Chugoku and Shikoku areas during the period from January 1979 to December 1988 using a questionnaire.
As a result of. this survey, 142 cases of coexisting active pulmonary tuberculosis and bronchogenic carcinoma were reported during the period.
The incidence of coexisting caseswas 2.32% of patients with pulmonary tublrculosis and 2.22% of patients with bronchogeniccarcinoma.
The foci of tuberculosis and carcinoma were found more often in the same lobe than indifferent lobes.
The proportions of histological types of bronchogenic carcinoma were asfollows; squamous cell carcinoma 43.9%, adenocarcinoma 36.0%, small cell carcinoma 16.5% and large cell carcinoma 3.6%.
These findings were not singnificantly different from thosein the general population. No significant difference in the proportions of histologicaltypes was found by coexisting lobe.
Some cases indicated that coexisting tuberculosis gave a favorable influence to theprognosis of lung cancer.
