Methods On the basis of the current state of head and neck cancers a decision analysis model was created to compare two treatment strategies for early tongue cancer. Expected value （EV） was calculated according to the literature which met the defined criteria. Sensitivity analyses were performed. Results The results showed that the decision model favored elective neck dissection （EV=0.87）, over ＂watchful waiting＂ （EV=0.77）. One-way sensitivity analyses demonstrated that the outcome was influenced by regional recurrence, threshold value of 0.28 for the elective neck dissection group and 0.17 for the ＂watchful waiting＂ group, and a salvage rate threshold value 0.73 for the ＂watchful waiting＂ group. Conclusions These results suggested that elective neck dissection strategy of the neck should be applied for early stage NO oral tongue carcinoma patients with no clinical nodal metastases. When the occult lymph node metastases rate was less than 0.17 and the salvage rate was more than 0.73, ＂watchful waiting＂ strategy would be preferable.展开更多

To provide clinical evidence for selective analyzing the characteristics and correlation of factors of occult with SCC of the tongue. is one of the most common cancers in the oral and neck dissection in management of cN0 patients by cervical lymph node metastases （OCLNM） in patients Methods From 2002 to 2006, 100 consecutive patients with SCC of the tongue were reviewed by analyzing the characteristics of OCLNM, diameter of the tumor, T classifications, depth of invasion, forms of growth, pathological grade and degree of differentiation. Results The rate of OCLNM in 100 patients with SCC of the tongue was 22%. The most common region with OCLNM was level Ⅱ in the ipsilateral neck, followed by levels Ⅰ and Ⅲ. There were 51.61% （16/31） of OCLNM in level Ⅱ and 87.10% （27/31） of OCLNM in levels Ⅰ-Ⅲ. There was no significant correlation between the diameter of tumor and OCLNM （P 〉0.05）. OCLNM was statistically significantly correlated with the depth of invasion, forms of growth, pathological grade and degree of differentiation （P 〈0.05）. The rate of occult metastases increased with the increased pathological grade, the decreased degree of differentiation and the increased depth of invasion. Conclusions The most common regions with OCLNM in cN0 patients with SCC of the tongue were levels Ⅰ-Ⅲ in the ipsilateral neck. Supraomohyoid neck dissection should be the elective treatment to the neck in patients with cN0 SCC of the tongue by consideration of the clinical and pathological factors for the depth of invasion, forms of growth, pathological grade, and degree of differentiation.展开更多
