口腔鳞癌发生颈淋巴结转移,将影响预后。据文献报道,单侧淋巴结转移者,5年生存率下降约50％;双侧淋巴结转移者,5年生存率下降75％;出现结外扩散者,生存率下降50％。单个淋巴结阳性,使远处转移率增加一倍(从6.9％到13.6％);3个淋巴结阳性者,远处转移率增加至48.8％。因此,手术前准确判断区域淋巴结受累情况,在口腔癌的治疗中十分重要。 除临床检查外,已有多种技术被用于检测颈淋巴结转移,例如超声检查(US)、CT和MRI等,但其准确性和预后判断价值仍有争议。作者回顾分析45例口腔
Oral squamous cell carcinoma of the neck lymph node metastasis, will affect the prognosis. According to the literature, the 5-year survival rate decreased by about 50% in patients with unilateral lymph node metastasis; the 5-year survival rate decreased by 75% in patients with bilateral lymph node metastasis; and the patients with extranodal diffusion had a 50% decrease in survival rate. Single lymph node positive results in a doubling of distant metastases (from 6.9% to 13.6%); distant node metastases increased to 48.8% in 3 lymph node positive individuals. Therefore, accurate assessment of regional lymph node involvement before surgery is very important in the treatment of oral cancer. In addition to clinical examination, a variety of techniques have been used to detect cervical lymph node metastasis, such as ultrasound (US), CT and MRI, but its accuracy and prognostic value is still controversial. The authors reviewed 45 cases of oral cavity
