[Clinical application of 125I particle implantation in children with rhabdomysarcoma of the head and neck].

OBJECTIVE: To study the efficacy and safety of 125I particle implantation in the treatment of rhabdomysarcoma (RMS) of the head and neck in children. METHODS: Eight children (four males and four females) with RMS of the head and neck received 125I particle implantation targeted to the primary lesion area. The primary lesions were noted in eyelids or eyes in two children, in the orbit in four children, and in the nasal cavity or nasal wing in two children. Treatment outcomes and side effects were observed. RESULTS: The follow-up visits averaged 45±17 months (median 43 months) in the eight children receiving 125I particle implantation. Five children achieved a complete remission, 2 children achieved a complete remission and 1 child died. The total survival rate was 88% in the 8 children. Local pigmentation was observed in all eight children (100%). Nubecula (one case), eyeball pain (one case), serious blurred vision (one case), cornea ulcer and blindness (one case) and bleeding of the nasal cavity (one case) were also observed. Except for nubecula and blindness, these side effects were improved by symptomatic treatment. CONCLUSIONS: 125I particle implantation appears to be effective in the treatment of RMS of the head and neck in children. Most treatment-related side effects can be improved by symptomatic treatment.
