在临床实践中发现传统的预后因素在预测口腔鳞癌的无瘤生存期方面的价值不大。ｅｒｂＢ癌基因在许多实体瘤的临床病程中具有重要作用，研究发现口腔鳞癌有ｅｒｂＢ癌基因扩增现象，为此，该作者研究ｅｒｂＢ癌基因作为口腔鳞癌标记物的可能性。用ｄｄ－ＰＣＲ方法测定了８５个 In clinical practice found that the traditional prognostic factors in the prediction of oral cancer-free survival of squamous cell carcinoma is of little value. The erbB oncogene plays an important role in the clinical course of many solid tumors. The study found that erbB oncogene amplification exists in oral squamous cell carcinoma. Therefore, the author investigated the possibility of erbB oncogene as a marker of oral squamous cell carcinoma. 85 were determined by dd-PCR
