肺癌的基因诊断已有报告，肺癌的癌基因异常主要是ｒａｓ基因组与ｍｙｃ基因组，其发生率占全肺癌的２０～３０％（表）。后者表肺癌时的基因异常－：０％；±：０～２５％；＋：２５～５０％；＋＋：５０～７５％；＋＋＋：７５～１００％。的扩增在小细胞型癌约为２５％... Genetic diagnosis of lung cancer has been reported. Oncogene abnormalities in lung cancer are mainly ras genome and myc genome. The incidence of lung cancer accounts for 20 to 30% of all lung cancers (table). In the latter case, the gene abnormality at the time of expressing lung cancer was -:0%; ±:0 to 25%; +: 25 to 50%; ++:50 to 75%; +++: 75 to 100%. The amplification is approximately 25% in small cell type cancer...
