Objective:

To explore and analyze the current situation of quality control of radioactive

125

I seeds implantation technology in Shanghai.

Methods:

According to the evaluation sheet of

125

I seeds implantation technology established by Shanghai Nuclear Medicine Quality C

ontrol Center

the data of 20 departments from 16 medical institutions was analyzed.

Results:

Among the 36 quality control contents evaluated for the basic requirements of medical institutions

personnel

and technical management

the highest compliance rate was 100.0% (36/36)

and the lowest compliance rate was 83.33% (30/36)

the management and quality situation of different departments in the same hospital also varies. For various indicators related to quality control

the average accuracy rate of implantation indications was 98.75%

the average preoperative treatment plan formulation rate was 94.74%

the average particle activity retest rate was 25.13%

the postoperative radiation dose verification average rate was 83.81%

the average incidence rate of major complications related to puncture within 30 d was 5.67%

the average incidence rate of major complications related to radiation injury within 30 d was 0.85%

and the average effective rate of particle implantation treatment was 92.2%

The all-cause mortality average rate within 30 days was 0.87%. The average follow-up rates for 2 months

4 months

6 months

and 1 yearwere 97.24%

91.9%

85.31%

and 71.91%

respectively. The average survival rates for 2 months

4 months

6 months

and 1 year were 96.81%

89.74%

81.31%

and 66.07%

respectively.

Conclusion:

In 2022

there were many problems in the quality control of

125

I particle implantation therapy technology in all medical centers in Shanghai. All medical centers should pay attention to it. According to the requirements of the

125

I particle implantation therapy technology evaluation form of nuclear medicine quality control center

medical centers should improve the department rules and regulations

and carry out the technology in full accordance with the diagnostic and therapeutic specifications.
