治疗舌癌最困难的问题之一是区域转移。根据不同作者的资料,舌癌的转移率为35～80%。从5年存活率看,有转移者23.8±3.8%,无转移者73.7±6.5%,所以必须早期查明区域转移并拟定预防措施。但是临床症状不显期,特别是颈部肥胖的病例,诊断区域转移有一定困难。另外,口腔感染和病灶周围炎症,引起颌下淋巴结肿大,使诊断越加复杂。据作者的资料,触到肿大的淋巴结误诊为转移者有12.4%,触不到肿大的淋巴结误诊为无转移者有40%。只根据临床症状难以判断有无转移,所以除了穿刺肿大的淋巴结以外,检查颈淋巴系统需用辅助方法:如放射性核素、
One of the most difficult problems in the treatment of tongue cancer is regional transfer. According to different authors, tongue cancer metastasis rate of 35 to 80%. According to the 5-year survival rate, there were 23.8 ± 3.8% of those with metastasis and 73.7 ± 6.5% of those without metastasis. Therefore, it is necessary to early identify the regional metastasis and draw up preventive measures. However, clinical symptoms are not significant, especially in cases of neck obesity, the diagnosis of regional transfer has some difficulties. In addition, oral infections and inflammation around the lesion, causing submandibular lymph nodes, making the diagnosis more complicated. According to the authors’ data, 12.4% misdiagnosed as swollen lymph nodes and 40% misdiagnosed as swollen lymph nodes. Only based on clinical symptoms difficult to determine whether the transfer, so in addition to punctate enlarged lymph nodes, the neck lymph system to check the need for ancillary methods: such as radionuclides,
