Abstract:
Objective To investigate the technological feasibility and short-term efficacy of 125I seeds implantation in head and neck cancer. Methods Thirty patients with head and neck recurrent cancer were treated with 125I seeds interstitial brachytherapy. The operation was performed under local anesthesia and the 125I seeds were implanted under the guidance of ultrasonography. The seed needles were implanted parallelly to each other, at 1～1.5 cm apart. The Mick applicator was used to implant seed at 1 cm interval. The radioactive activity per seed ranged 0.40～0.70 mCi, and the matched peripheral dose (MPD) was 90～160 Gy. The number of 125I seed implanted per lesion was 3～84 (median, 24). Ten patients with a seed radioactive dose
