该文旨在分析临床N0的唾液腺癌隐匿淋巴结转移方式。在119例临床N0的唾液腺癌接受原发灶切除及同侧颈淋巴清扫术的患者中,腮腺肿瘤80例(67%),临床分期T1:18%,T2:28%,T3:23%,T4:32%。25(21%)例患者经过病理证实出现颈部转移。腺瘤和高分化黏液表皮样癌的发病率最高(均为35%),颈淋巴转移最常见的区域为Ⅱ区(71%),其次为Ⅲ区(15%)及IB区(8%)。对组织学亚型进行多因
The purpose of this paper is to analyze the clinical N0 salivary gland carcinoma hidden lymph node metastasis. Among 119 patients with clinical N0 salivary adenocarcinoma undergoing primary resection and ipsilateral neck dissection, 80 cases (67%) had parotid tumors, clinical stage T1: 18%, T2: 28%, T3: 23% T4: 32%. Twenty-five (21%) patients had pathologically confirmed neck metastases. Adenomas and highly differentiated mucoepidermoid carcinomas had the highest incidence (both 35%). The most common cervical lymphatic metastasis was region II (71%), followed by region III (15%) and IB (8%) . Multiple histologic subtypes
