The advantages of heavy ion therapy for cancer

The advantages of heavy ion therapy for cancer:

1. Limited range, the beam can be stopped at any set position to protect the surrounding tissue of the tumor.

2. Dose inversion, low at the front and high at the rear, with energy deposited at the end of the range, can achieve true precision treatment.

3. The biological effects of high LET and high RBE values are amplified by at least 3-5 times in the peak region compared to photon therapy.

4. Inducing DNA double-strand breaks in tumor cells during the mitotic cycle, preventing them from dividing and proliferating.

5. Killing tumors does not rely on cell cycle or oxygen environment.

6. The choice of multiple or single segmentation can be made based on the condition of the surrounding normal tissues of the tumor to achieve optimal intensity modulation.

7. The heavy ion therapy can produce unique immune-enhancing effects, distant effects, and bystander effects.

8. The possibility of inducing secondary tumors is lower with targeted therapy compared to conventional radiotherapy.

9. The patient undergoes treatment easily and naturally without invasion, pain, or organ loss, with no traumatic psychological burden.

10. Almost no complications, low cost of postoperative rehabilitation treatment.

Compared with traditional radiotherapy, heavy ions have the following advantages:

Precision: Heavy ion therapy can concentrate more accurately on tumor tissue, reducing damage to surrounding healthy tissue.

The strong lethality of heavy ions is attributed to their physical properties, which allow them to release more energy within tumor cells, resulting in a more potent killing effect.

The indication is broad: applicable to various types of tumors, especially refractory tumors.
