喉癌组织恶性度与颈淋巴结转移关系

The relationship between histologic grading of malignancy and regional lymph node metastasis in squamous cell carcinoma of larynx

采用五因素评点法对40例喉鳞癌进行组织学和临床方面的研究。结果表明，组织恶性度与T分期无相关性，浸润方式弥散及恶性度高（评分≥11）的肿瘤发生颈淋巴结转移率显著高于有完整肿瘤边界者及恶性度低（评分≤10）者。提示喉癌组织恶性度在预测颈淋巴结转移上有实用价值，可指导临床治疗方案的选择。

Forty cases of squamous cell carcinoma of larynx have been studied by using five factors scale in order to investigate the relation between histologic grading of malignancy and regional lymph node metastasis. The results show that high degree malignancy tumor (which gets more than ten points) and diffusly invased tumor have a significantly higher proportion of regional lymph node metastasis than others. There was no relation between histologic grading of malignancy and T categories. It indicated that histologic grading of malignancy may be a good help in predicting patient evolution
