The Impact of Chemotherapy on the Lymphatic System in Thoracic Oncology

Non-small-cell lung cancer remains the leading cause of cancer-related mortality in the United States and Europe. Most patients are diagnosed with metastatic disease for which chemotherapy remains the cornerstone of treatment. In non-metastatic disease, surgery is the most potentially curative therapeutic option, but its outcome is still poor, in particular for patients with lymph node involvement. Therefore, several randomized adjuvant/neoadjuvant trials using chemotherapy and/or radiotherapy investigated the possibility of increasing the overall survival of patients with surgically treated lung cancer. The findings are reviewed in this article.
