手术、放疗及化疗对头颈部癌是有效的。手术切除肿瘤的核心,放疗消灭其周围边缘,化疗除去显微镜下所见的转移。手术或放疗足以治疗头颈部小的早期上皮癌(T、N。),局部控制及治愈率均高。有局部淋巴结转移的晚期上皮癌(T。,T‘,T‘,N:,NZ,N3)单J刀手术或放疗不适当,生存率低,合并疗法可以论制晚期癌。对晚期原发肿瘤或累及局部淋巴结的病人,需用术前放疗。中度放射量可控制氧合良好、放
Surgery, radiotherapy and chemotherapy are effective for head and neck cancers. The core of the tumor is surgically removed, radiotherapy is used to destroy its surrounding edge, and chemotherapy removes metastases seen under the microscope. Surgery or radiotherapy is sufficient for the treatment of early epithelial cancers with small head and neck (T, N.), with high local control and cure rates. Late stage epithelial cancer with regional lymph node metastasis (T., T’, T’, N:, NZ, N3) is not suitable for single-J-knife surgery or radiotherapy. The survival rate is low, and combined therapy can be used to develop advanced cancer. For patients with advanced primary tumors or involving regional lymph nodes, preoperative radiotherapy is required. Medium dose can control oxygenation well and put
