P017 - Investigation of Mediastinal Lymph Node Metastasis in Non-Small Cell Lung Cancer (ID 72)
00:00 - 00:00 | Author(s): H. Liu
To investigate the distribution of mediastinal lymph node metastasis in non-small cell lung cancer(NSCLC) and provide evidence for the range of mediastinal lymph node dissection.
Retrospectively analyze NSCLC patients underwent systematic lymph node dissection and confirmed mediastinal lymph nodes metastasis postoperatively.
78 cases were enrolled in this research. 11 in left upper lobe (14.1%), 27 in left lower lobe (34.6%), 16 in right upper lobe (20.5%), 4 in right middle lobe (5.1%), 20 in right lower lobe (25.6%). Among all left upper lobe cancers, 10 had upper mediastinal lymph node metastasis (66.7%); 5 subcarinal metastasis (33.3%), and no lower metastasis cases; in left lower cancers, 5 had upper mediastinal lymph node metastasis (13.5%), 17 subcarinal metastasis (45.9%), and 15 lower mediastinal metastasis (40.5%). For right upper lobe, 16 had upper mediastinal metastasis (64%), 6 subcarinal metastasis (24%), and 3 lower mediastinal metastasis (12%); for right middle lobe, 2 had upper mediastinal metastasis (33.3%), 3 subcarinal metastasis (50%), and 1 lower mediastinal metastasis (16.7%); for right lower lobe, 12 had upper mediastinal lymph node metastasis (34.3%), 11 subcarinal metastasis (31.4%), and 12 lower mediastinal metastasis (34.3%).
In all mediastinal lymph node metastasis cases , metastasis could emerge in the other locations except for left upper cancers with no lower mediastinal metastasis. It might be acceptable to perform mediastinal lymph node dissection of NSCLC, except for lower mediastinal lymph node in left upper lung cancer. However, further researches with larger amount of cases are required.
