To analyse the distribution of Neck metastases (NM) and to study frequency of skip metastases in oral squamous cell carcinoma (SCC) of oral cavity. From September 2012 to April 2013, 30 previously untreated patients with SCC of oral cavity underwent primary surgical treatment in our institution. From pathological report of Neck dissection specimen prevalence and distribution of NM were ascertained. All patients were classified according to American Joint Committee on Cancer 2005 TNM classification. Overall frequency of NM was 36.7%. Frequency of occult metastases was 33.3%. N+ metastases found in 37% cases. The overall frequency of NM in level IV and V was 9.5%. Isolated level III involvement was found in 3.3%. No isolated level IV and V involvement was found. Skip metastases to level III LN was 6.7%. We did not find any skip metastases to level IV in our study. Neck nodes at greater risk for metastases were level I and II (50 and 28.6%). Level III (11.9%), IV (7.14%), V (2.38%). The risk of skip metastases to level IV was nil in our study.
分析口腔鳞状细胞癌(SCC)颈部转移(NM)的分布情况,并研究跳跃转移的发生率。2012年9月至2013年4月,30例先前未经治疗的口腔SCC患者在我院接受了初次手术治疗。根据颈部清扫标本的病理报告确定NM的发生率和分布情况。所有患者均按照美国癌症联合委员会2005年TNM分类进行分类。NM的总体发生率为36.7%。隐匿性转移的发生率为33.3%。37%的病例发现N+转移。IV级和V级NM的总体发生率为9.5%。发现孤立的III级受累为3.3%。未发现孤立的IV级和V级受累。跳跃转移至III级淋巴结为6.7%。在我们的研究中未发现跳跃转移至IV级的情况。转移风险较高的颈部淋巴结为I级和II级(分别为50%和28.6%)。III级(11.9%),IV级(7.14%),V级(2.38%)。在我们的研究中,跳跃转移至IV级的风险为零。
