I-125 seed implantation has been widely applied in the local treatment of advanced malignant tumor. It has the advantages of providing a high dose of treatment to the target sites and low dose to normal tissues. It has been mostly applied as palliative treatment for recurrences in advanced malignant tumor (except for prostate cancer), suppressing tumor development and improving the quality of life of patients.


The objective of this study was to investigate changes in quality of life for patients with advanced malignant tumor after receiving I-125 seed implantation using a three-dimensional (3D)-printed individualized template and computed tomography (CT) guidance.

Materials and Methods:

In this prospective study, convenience sampling was applied for patients with advanced tumors attending a tertiary hospital. The European Organization for Research on Treatment of Cancer Quality of Life Questionnaire-C30 was involved to assess quality of life. Patients completed the questionnaire before and 24 h after seed implantation. The questionnaire of 1 and 3 months after seed implantation was completed by telephonic follow-up.


A total of 42 patients were included (24 males and 18 females), with an average age of 58.86 ± 14.13 years (ranged 25-91 years). The average scale score after seed implantation was higher than that of before implantation. The order was the average scale score 1 month after seed implantation >3 months after seed implantation >24 h after seed implantation.


The results suggested that the quality of life could be improved with I-125 seed implantation using a 3D-printed individualized template under CT guidance in patients with the advanced malignant tumor.
