摘要
By using the immunohistochemical technique(ABCmethod), 186 cases of cerebral metastatic tumors labeled with McAb against human lung carcinoma are reported. They were divided into two groups: primary site determined group and undetermined group. In determined group(59 cases) . 33/36 cases( 91. 6 % ) of lung carcinomas showed HLC3 positive reactions, but among 23 cases of other cancers, only two cases showed weak positive reactions.This result indicated that the HLC3 have strong specific reaction to the lung carcinomas. In undetermined group( 127 cases), 68 cases of metastatic tumors reacted to HLC3 positively. In all 186 cases of cerebral metastatic tumor, there were 101 cases( 53. 5%) showing positive reaction to HLC3- AB. Among 125 cases of cerebral metastatic adenocarcinoma, 76 cases( 61 %) showed positive reactions with HLC3-AB. The result in this paper proved that the lung carcinoma was the important primary site of the cerebral metastatic tumor operated neurosurggically. The specifity of McAb HLC3- AB, the incidance of the cerebral metastatic lung carcinoma and its metastatic course were discaussed.
