title: [An epidemiologic study on patients with lung disease, using a data base management system and the histopathologic diagnosis].
abstract: A new pathologic data base management system was introduced in the Section of Pathology, Clinical Laboratory, of this hospital for an efficient sorting and searching past data and for the rapid epidemiological study of them. By the use of this system, the incidence and the age and sex distribution of various diseases were studied in a total of 1,264 patients received pathological examination for surgically operated specimens or biopsied materials at the Chest Disease Research Institute Hospital, Kyoto University, from January, 1986 to December, 1988. A gradual increase in the number of frozen section samples of surgically removed organs and of open lung biopsies was noted during this period. Adenocarcinoma, squamous cell carcinoma, small cell carcinoma and large cell carcinoma amounted to 42.5%, 32.9%, 12.2%, and 7.5% of primary lung cancers, respectively. The male-to-female ratio of patients with primary lung cancers was 2.9:1 but there was no significant difference in the age distribution among four types of the primary cancers in both sexes. Two hundred and ninety nine (32.6%) patients were diagnosed as non-neoplastic lung diseases: 121 infectious (13.2%), 69 granulomatous (7.5%), 62 pulmonary fibrotic (6.8%) and 47 miscellaneous non-neoplastic (5.1%) diseases.
