Advantages of Heavy Ion Therapy
- Superior Dose Localization
- Heavy ion therapy can severely damage the tumor while minimizing damage to surrounding tissues. Heavy ion therapy has less toxicity (adverse effects) than conventional radiotherapy.
- Effective Against Cancers Which are Resistant to Conventional Radiations
- Heavy ion beams have stronger biological effects than X-ray. For example, heavy ion therapy is more effective against tumors such as osteosarcoma, which are difficult to cure with conventional X-ray radiotherapy.
- Short Treatment Time
- The treatment time for heavy-ion radiotherapy is relatively short (3 weeks on average). Compared to conventional X-ray radiotherapy, which requires 6-7 weeks, the treatment time can be reduced dramatically.
Comparison with orher therapies
|Indications||・Localized Cancer (mainly early-stage diseases)|
|Advantage||・Considered more likely to be curative.|
|Disadvantage||・Relatively large deprivation of organ function and morphology
・Indication for surgery can be limited due to location of cancer and conditions of patients (age, concomitant diseases, etc)
(from early-stage to advanced-stage diseases)
|Advantage||・Relatively smaller damage to organ function and morphology.
・Relatively smaller damage to the patient.
・The treatment results for early-stage cancer in selected sites are equivalent to those of surgery.
|Disadvantage||・The financial cost for particle therapy is more expensive compared to other therapies.
・Adverse effects can occur in organs near the tumors.
(Cancer with metastasis & hematological cancer such as leukemia)
・Used in combination with other therapies for localized cancer
|Advantage||・Can sometimes prolong patients’ lives by suppressing the progression of cancer.|
|Disadvantage||・Can cause systemic adverse effects.|
