Map of sentinel lymph node from oral cancers for image diagnosis

1）利用Filemaker Pro 5.5开发了口腔癌颈部淋巴结转移影像诊断报告系统。该系统具有颈部淋巴结定位的自动映射功能。将本研究设计的淋巴结编号输入个人电脑，淋巴结便显示在颈部的图示上。淋巴结编号由两位数字组成。左侧数字表示颈部水平;右侧表示淋巴结在该水平的位置。图示上移位的淋巴结大小反映了图像上的淋巴结大小。另外，当诊断为转移时，图示上的淋巴结显示为红色，当诊断为可疑转移时，图示上的淋巴结显示为粉红色，当诊断为反应性增大时，图示上的淋巴结显示为白色。在此基础上对口腔癌前哨淋巴结的定位进行了评价。我们认为，当癌的原发部位是舌时，前哨淋巴结是21、30或31个淋巴结，当癌的原发部位是下牙龈时，前哨淋巴结是13-15个淋巴结，当癌的原发部位是口腔底时，前哨淋巴结是11或12个淋巴结。

1)We developed image diagnostic reporting system for cervical lymph node metastases in oral cancer patients using Filemaker Pro5.5. Our system has automatic mapping function of lymph nodes location in the neck. Lymph node is displayed on illustration of the neck, when lymph node number, which we devised in this study, is inputted in personal computer. Lymph node number is composed of a number with two digits. Left number means the level of the neck ; right the location of lymph node in the level. Size of lymph node displaced on the illustration reflects lymph node size on images. Also, lymph node on the illustration is presented in red color, when it is diagnosed as metastasis, pink when as suspicious metastasis, white when as reactive enlargement.2)We compared image diagnostic reports for lymph node in oral cancer patients with histopathologic diagnosis of these lymph nodes. The location of sentinel lymph node in oral cancer was evaluated on basis of this result. We consider that sentinel lymph node is lymph node number 21, 30 or 31 when primary site of cancer is tongue, 13-15 when lower gum, 11 or 12 when oral floor.
