ABSTRACT
Objective To evaluate the feasibility of interstitial implantation of ~(125)I seeds for recurrent or metastatic malignant tumor at the Head and Neck.Methods From January 2003 to July 2007,29 patients received interstitial implantation of ~(125)I seeds in our hospital because of recurrent or metastatic malignant tumors at the head or neck after surgery or chemotherapy.Under local anesthesia and guidance of CT,B-ultrasonography,or endoscopy,~(125)I seeds were implanted into the tumor tissues with intervals of 0.5-1.0 cm.The matched peripheral dose(MPD)was 90-160 Gy,and the radioactive activity was set at 29.6 MBq per seed.Results The operation was completed in all the patients.A median of 23 seeds(12-67)were implanted in each case.No complications,such as hemorrhage,infection,or seed migration,occurred in the patients.The patients were followed up for 3-24 months(mean,16 months).During the period,the rate of local control was 55%(16/29)at 3 months,71%(20/28)at 6 months,45%(10/22)at 12 months,and 36%(5/14)at 2 years.Conclusion Interstitial implantation of ~(125)I seeds is feasible for recurrent or metastatic tumor at the head or neck with a good short-term outcome.
