The predictors of hilar and mediastinal lympho node metastasis in non-small cell lung cancer
Main Article Content
Abstract
From 01/01/2012 to 31/12/2016 there were 109 cases of primary non-small cell lung cancer treated by VATS lobectomy and lymphadenectomy with an average age of 59.18 ± 10.08 (31 - 80), of which 59 males (54.1%), 50 females (45.9%). The average lung tumor size was 3.23 ± 0.91 (1.2-5cm). A total of 419 nodal stations were examined, and surgery showed that 309 positive lympho node stations, 110 negative lympho node stations. The location of lympho node and the potential of metastasis (p = 0.112), the number of lymph nodes removed at each lympho node station and the probability of metastasis (p <0.001), lympho node size and the potential of metastasis (p <0.001). The location of the lung tumors and metastasis of the lymph nodes (p> 0.05), lung tumor size and lymph node metastasis (p <0.05), metastasis of lymph nodes and histopathology (p> 0.05), tumor differentiation (p <0.05). The factors related to lymph node metastasis include: number of lymph nodes at each station, tumor size, histopathology and tumor differentiation. However, only the location of tumor is not related to the ability to lymph node metastasis in non-small cell lung cancer.
