Part 1 Flashcards
Is a clinical and scientific endeavor devoted to the management of patient with cancer and any other diseases by ionizing radiation alone or combined with other modalities, investigation of the biologic and physical basis of radiation therapy and training of professionals in the field
Radiation Oncology
is a clinical modality that deals with the use of ionizing radiation, in the treatment of patient with malignant (occasional non-malignant) neoplasms. The aim of radiotherapy is to delivery a precise dose of radiation to a defined tumor volume with a minimal damage as possible to the surrounding healthy tissues.
Radiation Therapy
Types of radiation therapy
External Beam Radiation Therapy/Internal Radiation Therapy
Radiation therapy that uses a machine located outside the body and aims high energy x-rays to the cancers cells (Give examples)
External Beam Radiation Therapy
Ex: Linear Accelerator, Gamma Knife, Proton Therapy
Radiation Therapy that delivers radiation internally by ingestion or by direct contact to the source
Internal Radiation Therapy
Ex: Brachytherapy, Radionucleid Therapy
A medical specialist certified in the practice of radiation oncology by the philippine board of radiation oncology, and is responsible for the consultation, dose prescription, on-treatment supervision and evaluation, treatment summary reports, follow up monitoring and evaluation of treatment outcome morbidity.
Radiation Oncologist
A duly licensed by the Professional Regulation Commission (PRC), who is practicing radiotherapy technology and is responsible for operating simulators, Computed Tomography Scanners, treatment units, etc. for accurate patient set-up and delivery of a planned course of radiation therapy prescribed by the radiation oncologist and for documentation of treatment
Radiologic Technologist/Radiation Therapy Technologist.
An expert on the medical use of radiation and responsible for dose calculations and planning the radiation treatment of the patient ensuring that the prescribed dose is delivered optimally while sparing the surrounding organs.
MEDICAL PHYSICIST / DOSIMETRIST
Are professional nurses collaborated with the team and are responsible for patient assessment, information dissemination regarding the treatment process and possible side effects.
RADIATION ONCOLOGY NURSE
This kind of treatment is intended to cure the patient, it is projected that the patient has a probability of surviving after adequate therapy even if the chance is low. In such patients, the area to be treated includes the tumor and any area where there is known risk of disease being present.
CURATIVE
Treatment that aims to lessen the signs and symptoms of the disease for patient comfort. This kind of treatment are for patients with incurable disease.
PALLIATIVE
Advance procedure that is responsible for the treatment and or eradication of tissues that has a high risk of developing neoplasia
Prophylactic
- The dose prescribed for and received by the patient; it is the required dose of energy absorbed by the patient at the target site from the radiation beam
Absorbed Dose
Gray (Gy) is the SI unit of ______
1 rad = ___ or___
Absorbed Dose
0.01 Gy or 1cGy
The maximum amount of dose that can be accepted by the normal tissue to prevent normal tissue cell death.
Tolerance Dose
