Abstract:
Objective:To preliminarily evaluate the safety and efficacy of 3D printing template-assisted brachytherapy in the treatment of solitary metastatic lymph nodes adjacent to iliac vessels.Methods:Clinical data of 12 cases of para-iliac lymph node metastasis after radiotherapy admitted to our hospital from October 2018 to April 2020 were retrospectively analyzed. All patients received 3D printing template-assisted brachytherapy at a prescription dose of 20-30 Gy/fraction. CT scan was reviewed every 1 month in the first 3 months after treatment and every 3 months at 3 months after treatment.Local control rate, symptom relief rate and adverse events were evaluated.Results:All the 12 patients successfully completed the treatment and follow-up. At 1, 3 and 6 months after 3D printing template-assisted brachytherapy, 2, 2 and 3 patients obtained complete remission of lymph nodes, 9, 8 and 8 cases of partial remission, 1 case of stable disease and no case of disease progression. The symptoms were relieved in 10 patients. Acute radiation enteritis occurred in 2 patients and myelosuppression in 2 patients, which were mitigated after symptomatic treatment.Conclusion:3D printing template-assisted brachytherapy may be an efficacious and safe treatment of para-iliac lymph node metastasis, which yields tolerable adverse events.
