The Importance of Definition Clinical Target Volume in 125I Seed Implantation Lung Cancer: A Retrospective Case Series

Lung cancer is the leading cause of cancer deaths in the China and worldwide. In terms of unresectable patient, locoregional treatment improved progression free survival and overall survival, including radiotherapy and thermal ablation. Radiotherapy is comprised of external beam radiotherapy (EBRT) and brachytherapy (BT). BT, including 125I radioactive seed implantation, has been used in malignant thoracic tumor, especially in post-chemoradiotherapy. Despite 125I seeds is feasible and effective for patients with malignant thoracic tumors, how to define clinical target volume (CTV) and gross tumor volume (GTV) are concerned by radio-oncologist.
