Excerpt
Mediastinal lymph node (LN) dissection is an important component in lung cancer surgery due to its crucial impact on accurate lymph node staging and potential therapeutic effect on micrometastasis.
1 Station 3A LN is located in the anterior mediastinum and in front of superior vena cava. In the past, station 3A LN was considered as a side path of lymphatic spread because of the hindrance of superior vena cava. Therefore, tumor metastasis to this position might be uncommon.
2 As a result, station 3A LN dissection in patients with right-sided non-small cell lung cancer (NSCLC) is generally neglected during routine clinical practice. Previous sporadic studies have reported the removal of station 3A LNs with the metastasis rate ranging from 2.9 to 17.8%,
2,
3 indicating that the involvement of station 3A LNs was not rare. However, the clinical significance of station 3A LN dissection in patients with right-sided NSCLC is mostly unknown. …
