Indications for Proton Therapy
Proton therapy is an advanced and precise method of oncological treatment used for a variety of cancers. Here are the most common indications for this type of therapy:
1. Brain and Central Nervous System Tumors
Treating these types of cancers often requires a combination of surgery, radiation therapy, and chemotherapy. When radiation therapy is necessary, it is crucial to accurately target the radiation dose to the tumor due to its proximity to vital healthy tissues, such as the brain and optic nerves. Proton therapy is superior to conventional X-ray therapy because it reduces radiation exposure to healthy tissues, minimizing side effects like neurological dysfunctions and the risk of secondary tumors.
2. Ocular cancers
Treating ocular cancer, especially ocular melanoma, is challenging due to its proximity to vital organs. Proton therapy allows for the delivery of high doses of radiation directly to the tumor without affecting surrounding tissues, such as the cornea and retina, thus protecting patients’ vision.
3. Pediatric cancers
Proton therapy is extremely effective in pediatric oncology. Given the survival rates of 70-80% and long-term life expectancy, it is crucial to find treatment forms that minimize side effects on the quality of life of children. Clinical studies show that proton therapy provides an effective solution in this regard.
4. Head and Neck Cancers
Research suggests that proton therapy is superior to intensity-modulated radiation therapy (IMRT) regarding survival and tumor control. It significantly reduces the rates of acute dysphagia, gustatory dysphagia, mucositis, and nausea.
5. Re-irradiation
When a patient has been previously irradiated, the risks of adverse effects increase. Proton therapy allows for a higher radiation dose to be delivered directly to the tumor while minimizing exposure to healthy tissues, making it ideal for patients requiring reirradiation.
6. Sarcomas
Bone and soft tissue sarcomas are excellent candidates for proton therapy, as they require high curative doses and are often located near sensitive tissues. Proton therapy enables precise treatment that minimizes the risk of damage to healthy tissues.
7. Prostate Cancer
Proton therapy is also indicated for the treatment of prostate cancer. This method allows for precise targeting of radiation to the tumor, reducing the risks of severe toxicity that can arise due to proximity to critical structures such as nerves, the rectum, and the bladder. Thus, proton therapy can improve patients’ quality of life by minimizing side effects.
