Advantages of iodine-125 seed implantation

1. More precise treatment positioning: It is performed under the guidance of CT and ultrasound, with precise positioning and no damage to normal tissues.

2. Long duration: After the particles are implanted, they can kill tumor cells every minute and every second without stopping for 24 hours, for up to 180 days.

3. Significant therapeutic effect: Continuous, low-dose, high-precision radiotherapy, repeated irradiation for 24 hours, can effectively inhibit the proliferation of tumor cells.

4. Low radiation energy: The irradiation distance is only 1.7 cm, and most of the energy is absorbed by the tumor tissue, causing slight damage to surrounding tissues, organs and normal cells, and mild systemic toxic and side effects.

What diseases are suitable for treatment with iodine-125 seed implantation?

Iodine-125 seed implantation offers advantages for certain tumors that recur or metastasize after surgery. It can be used not only as the primary treatment for tumors but also as a preferred treatment option for some tumors, such as prostate cancer.

Iodine-125 seed implantation is a good option for patients with solid tumors who are unwilling to undergo radical surgery or for those who are inoperable. Furthermore, for patients with metastatic tumors (but not extensive metastases), iodine-125 seed implantation can not only effectively control metastatic growth but also maintain organ function and alleviate pain. Iodine-125 seed implantation is also an option for patients whose tumors cannot be surgically removed due to factors such as physical condition and tumor location.

To provide cancer patients with a more comprehensive treatment system, Guangzhou Royal Cancer Hospital is actively introducing cutting-edge technologies. Currently, iodine-125 seed implantation has passed the qualification review of relevant national departments, bringing good news to cancer patients.
