中文摘要 | 回顧138位完成頸部廓清手術的口腔癌患者,評估其術前的電腦斷層掃描影片和術 後組織病理檢查的相關性,依電腦斷層掃描影片中最大淋巴結的大小分為4組,最大淋巴結 小於10mm時為甲組、淋巴結大於等於10mm而小於15mm時為乙組、介於15至20mm時為丙組、大 於20mm時為丁組;甲組20%有頸部淋巴結轉移,乙組16.7%有頸部淋巴結轉移,丙組60.5%有 頸部淋巴結轉移,丁組全部有頸部淋巴結轉移。所有患者中,若次大淋巴結小於10mm時,有 29%的頸部淋巴結轉移率;若次大淋巴結大於或等於10mm時,有58.1%的勁部淋巴結轉移率, 以卡方檢定分析次大淋巴結大小和勁部淋巴結轉移率有明顯相關性(p=0.003)。 但以Logistic regression分析時,在調整最大淋巴結大小的因素後,次大淋巴結大小及第 三大淋巴結大小和頸部淋巴結轉移並無明顯相關性。總結來說,以Logistic regression分 析電腦斷層掃描影片中和頸部淋巴轉移有關之因素主要為最大淋巴結有大小(p=0.003)和 有無中央壞死(p=0.0123),當淋巴結大於15mm以上時,轉移率就會明顯增加,然而電腦掃 描影片中次大淋巴結的大小(p=0.96)及第三大淋巴結大小(p=0.89)和淋巴轉移並無明顯的 相關性。 |
英文摘要 | A retrospective study was undertaken to evaluate the relationship between computer tomography (CT) and pathological metastasis in 138 patients with squamous cell carcinoma of the oral cavity who underwent radical neck dissection or suprahyoid neck dissection from 1994 to 1998. CT scans were performed during infusion of an intravenous contrast medium (lopamiro) before surgery. The subjects were then divided into four groups according to the size of the largest lymph node that appeared on the CT. Group A contained those patients whose largest lymph node was just under 10mm, group B from 10 to 15mm, group C from 15 to 20mm, and group D over 20mm. Twenty percent of group A 16.7% of group B, 60.5% of group C, and 100% of group D had neck lymph node metastasis Moreover, it was notable that in group C, those who combined central necrosis, 77% of them had lymph node metastasis. Twenty nine percent of all the subjects had neck lymph node metastasis if the second largest lymph node was under 10mm, whereas 58.1% of the subjects had neck lymph node metastasis if their second largest neck lymph node was larger or equivalent to 10mm. There was a significant relationship between the size of the second largest lymph node and cervical metastasis (p=0.003). However, adjusting the factor of the size of the largest lymph node by Logistic Regression Analysis, there was no significant relationship between neck lymph metastasis and the size of the second largest lymph node as well as the size of the third largest lymph node. In other words, a significant relationship was found between the lymph nodes (size and central necrosis) and the pathologi cal metastasis of the neck using Logistic Regression Analysis (P=0.003, P=0.012). The rate of pathological metastasis to the neck obviously increases if the size of the lymph node is larger than 15mm. But the size of the second and third largest lymph nodes carry no significant relationship with pathological metastasis. |
