Despite the progress that has been achieved using modern methods of therapy, cancer currently remains one of the greatest problems within medicine. In developed countries approximately one in three people suffer from, and one in five die of, malignant disease. The Czech Republic has one of the highest death rates from cancer in the world (within the top ten).
Radiotherapy is one of the most economical methods of treatment for malignant diseases with a relatively high rate of effectiveness. In developed countries radiotherapy is currently used in 50 – 60% of patients with malignant tumors and its contribution to complex therapy continues to increase. From this number, one third of patients are treated exclusively with radiotherapy and almost two thirds of patients are treated with radiotherapy in combination with surgery, chemotherapy, hormonal therapy or biological targeted therapy.
Proton therapy is a highly precise method of radiotherapy, mainly due to the physical properties of
protons themselves, as well as to the specific way proton doses are distributed within tissues. The
utilisation of this method results in high local control over tumors, a lower probability of damage to
surrounding healthy tissues, a low risk of complications and a higher chance of rapid recovery following
|Advantages of proton therapy|
During conventional radiation, a beam of photons
transfers the greatest dose of radiation to the front of the tumor, after which the radiation penetrates the tumor and healthy tissues of the patient behind the tumor. In contrast, a proton beam transfers a minimal dose of radiation to the front of the tumor, a maximal dose to the tumor area itself and no dose behind the tumor. Therefore, proton therapy is safer for healthy tissue surrounding the tumor.
The treatment is suitable for all patients regardless of age, mainly depending on diagnosis. There are great results being achieved in the treatment of tumors in children, where the use of conventional photon radiation or chemotherapy is associated with a high risk of side effects and complications.
