恶性肿瘤对患者最大的威胁之一是它具有转移的特性,往往在原发瘤被控制后,由于发生转移而使患者丧失生命。淋巴道是癌转移的主要途径之一,大多数中、晚期癌症患者很早就出现淋巴结转移,特别是颈部淋巴结转移最为明显,因此颈部淋巴结穿刺对确定诊断、转移和追踪原发病灶在临床上有其重要意义。 One of the greatest threats to a patient from a malignant tumor is its metastatic nature, which often results in loss of life due to metastasis after the primary tumor is controlled. Lymphatic tract is one of the main pathways for cancer metastasis. Lymph node metastasis occurs very early in most patients with advanced and advanced cancers, especially cervical lymph node metastasis. Therefore, cervical lymph node puncture is essential for the diagnosis, metastasis, and tracking of primary lesions. Clinically significant.
