CANCER TREATMENT (ONCOLOGY)
Radiation oncology is the discipline that examines, through the use of ionizing radiation, the effects of radiation on the cancer, the behavior of tumors and also covers research in this field. Radiation oncology has two areas of application: Radiotherapy and Radiosurgery.
Radioterapia (terapia cu raze X)
Radiotherapy is defined as the treatment of the cancerous tissue or of some non-malignant tumors with radiation. It is also colloquially referred to as “radiation therapy” or “x-ray therapy”. The beams used in radiotherapy aim to stop cancerous cells from growing or to kill them. Radiotherapy is applied frequently in the treatment of cancer. As such, after being diagnosed with cancer, 60-80 % of cancer patients need at least one dose of radiotherapy.
Treatment Devices Used in the Application of Radiation Oncology:
Rapidarc is a high-tech radiotherapy device that reduces the amount of time patients have to undergo radiation therapy. It provides greater comfort and ease for the patient by reducing the length of radiotherapy sessions from 15-30 minutes to as little as 2 minutes.
Trilogy is a type of linear accelerator, or in other words a LINAC device, used in radio therapy treatment. The Trilogy device unites the various features found in other devices, allowing accurate intervention by specialists in the shortest amount of time and to an ideal proportion. This means the patient receives the most accurate treatment in the shortest amount of time.
Brachytherapy is a method used to raise local control of the disorder by increasing the dose of radiation applied to the tumor before and after external radiotherapy. However, it may also be used on its own for curative purposes in patients whose situation is suitable for such treatment.
In brachytherapy, radioactive sources are placed in the tumor and target tissues with unique methods, thus limitation of dose around sources is provided.
Techniques Used in the Application of Radiation Oncology:
IGRT : Image Guided Radiation Therapy
IMRT : Intensity Modulated Radiation Therapy
Conformal Radiotherapy : 3D Conformal Radiotherapy
SRT / SRS : Stereotactic Radiotherapy / Stereotactic Radiosurgery
