High‐activity iodine‐125 endocurietherapy for head and neck tumors

Abstract
Inoperable solid tumor recurrence within a surgical bed or within a previously irradiated field usually responds poorly to re‐treatment with conventional external beam irradiation (EXRT) and/or chemotherapy. We present a new, alternative method of re‐treatment used in two patients with recurrent head and neck cancer involving the parotid (adenocarcinoma) and neck nodes (squamous cell carcinoma). These patients were successfully re‐treated with high‐activity 125iodine (I‐125) permanent implantation.
