OBJECTIVE: To evaluate the feasibility of positron emission tomography combined with computed tomography (PET-CT)-guided (125)I seed implantation in the treatment of patients with refractory nasopharyngeal carcinoma after repeated traditional radiochemotherapy.
STUDY DESIGN: Case series with chart review.
SETTING: University medical center.
SUBJECTS AND METHODS: A total of 26 patients (18 men, 8 women; mean age, 51.3 ± 10.8 years; totaling 53 lesions with an average diameter of 2.86 ± 1.61 cm) were treated by PET-CT-guided (125)I seed implantation. All of the patients received a PET-CT scan 2 months after the treatment. Follow-up was conducted for ~2 to 43 months (median, 28.2 months) to observe the local control rate, overall survival rate, and clinical complications.
RESULTS: The local control rates of refractory nasopharyngeal carcinoma after repeated traditional radiochemotherapy after 3, 6, 12, 24, and 36 months were 90.6% (48/53), 79.3% (42/53), 71.7% (38/53), 62.3% (33/53), and 56.6% (30/53), respectively. The overall 1-, 2-, and 3-year survival rates were 87.2%, 71.3%, and 56.5%, respectively, with a median survival time of 28.2 months. Of all patients, 19.2% (5/26) died of local recurrence and 15.4% (4/26) died of metastases. One patient died of hypertensive cerebral hemorrhage, and another patient died from cachexia and infection. The long-term complications included hyperpigmentation at operative sites (n = 5), insensible feeling on the lateral cheek (n = 2), dryness of the oral cavity (n = 1), and headache (n = 1).
CONCLUSION: PET-CT-guided (125)I seed implantation is an acceptable and feasible method for treating refractory nasopharyngeal carcinoma with minimal damage and few complications.
