Iodine-125 Brachytherapy for Palliative Treatment of Painful Colorectal Cancer Port-Site Metastases.

OBJECTIVE:To summarize the treatment process of a case of Iodine-125 Brachytherapy for Palliative Treatment of Painful Colorectal Cancer Port-Site Metastases. METHODS:We present a case report of multifocal port-site metastases ( PSMs ) that developed in a patient with stage IV ascending colonic adenocarcinoma and mucinous cancer following laparoscopic surgery. After multiline therapy failed, painful PSMs treated with repeated iodine-125 seed implantation. RESULTS:Severe abdominal discomfort were eventually successfully managed after receiving iodine-125 brachytherapy. CONCLUSION:For painful PSMs, iodine-125 brachytherapy can be a safe and effective treatment option.
