Impact of target area selection in Iodine seed brachytherapy on locoregional recurrence in patients with non-small cell lung cancer.

Background: Computed tomography (CT)-guided percutaneous implantation of Iodine radioactive seeds requires the precise arrangement of seeds by tumor shape. We tested whether selecting target areas, including subclinical areas around tumors, can influence locoregional recurrence in patients with non-small cell lung cancer (NSCLC).

Method: We divided 82 patients with NSCLC into two groups.
