title: [Study of the difference between the clinical diagnostic criteria and results of immunohistochemical staining].
abstract: If more than 2 lesions of cancer are observed in the lung, differences in the histology or in situ component is the basic criterion for multicentricity. In addition, remote lung mass with same histology in the absence of both distant metastasis and mediastinal lymphadenopathy is also regarded as multicentricity. We have studied the difference between the clinical diagnostic criteria and the results of immunohistochemical staining. Thirteen patients who were diagnosed as double lung cancers under the clinical of Martini et al or Cortese et al were reviewed. Of them, clinically 6 patients had synchronous double lung cancers and 7 patients had metachronous double lung cancers. Four patients in each group with combination of adenocarcinoma (AD) and bronchiolo-alveolar cell carcinoma (BAC) were studied by immunohistochemical staining. As the result, 3 patients in the former group were defined as the synchronous double lung cancers, however in the latter group, only 1 patients was defined as the metachronous double lung cancers. As for from the histological findings, if either of multiple lung cancer lesion were Noguchi's A or B typed BAC, the patients are prone to have double lung cancers. Subsequently if the histology of the both lesions were the same as AD-AD or Noguchi's C typed BAC-BAC, then the patients are prone to have the metastatic lung cancers.
