Radiation oncologist

Radiation Symbol

A radiation oncologist is a specialist physician who uses ionizing radiation (such as megavoltage X-rays or radionuclides) in the treatment of cancer. Radiation oncology is one of the three primary specialties, the other two being surgical and medical oncology, involved in the treatment of cancer. Radiation can be given as a curative modality, either alone or in combination with surgery and/or chemotherapy. It may also be used palliatively, to relieve symptoms in patients with incurable cancers. A radiation oncologist may also use radiation to treat some benign diseases, including benign tumors and neoplasm. In some countries (not the United States), radiotherapy and chemotherapy are controlled by a single oncologist who is a "clinical oncologist". Radiation oncologists work closely with other physicians such as surgical oncologists, interventional radiologists,  internal medicine subspecialists, and medical oncologists, as well as medical physicists and technicians as part of the multi-disciplinary cancer team. Radiation oncologists undergo four years of oncology-specific training where as oncologists who deliver chemotherapy have two years of additional training in cancer care during fellowship after internal medicine residency in the United States.

Role of the Radiation oncologist

The Radiation oncologist is responsible for preparing the treatment plan where the radiation is required. Some of the treatment methods are radioactive implantations (Brachytherapy), external beam radiotherapy, hyperthermia, and combined modality therapy such as radiotherapy with surgery, chemotherapy, or immunotherapy.

Preparation

According to the Washington University School of Medicine in St. Louis "Training consists of a minimum of five years of postgraduate education. The first year of postgraduate clinical training must be spent in an accredited internship (medicine), family practice, surgery, pediatrics, or transitional year program followed by four years of training in radiation oncology."

Equipment

Anterior Pancoast tumor CT scan

To provide the treatment correctly, a series of equipment is needed which will help to complement it. First, a simulator and treatment preparation must be carried out, this consists of locating the area where the tumor is located to know where exactly the patient will be exposed at the time of treatment. The equipment used to perform this work is a computed tomography CT scan, magnetic resonance imaging (MRI), and W x-ray. After this, the place where the patient will be treated is marked and an immobilizer is created which will help at no time to expose another area of the body to this radiation. To complement this immobilizer they use tape, foam sponges, headrests, molds, and plaster cast. Also when the treatment is in the area of the head and neck is used a thermoplastic mask. This mask is exactly molded to your shape, to later secure it on some screws that the treatment table has, which helps to better mobilize the patient. When the entire treatment plan is ready, the patient will be assigned (it will depend on his type of cancer and the stage he is in) the days he will visit the clinic to perform the treatment and monitor him.

Treatment

The Radiation Oncologist provides two types of treatments which are classified as external and internal radiation therapy. External radiation therapy uses high-energy photon beams to kill cancer cells and shrink tumors. Internal radiation therapy is a systemic treatment that involves swallowing, injecting, or implanting a radioactive material, such as radioactive iodine.

Training (by country)

United States

In the United States, radiation oncologists undergo four years of residency (in addition to an internship), which is more dedicated to oncology training than any other medical specialty. Currently, radiation oncology is among the most competitive specialties in terms of residency match rates. During the four years of post-graduate training, residents learn about clinical oncology, the physics and biology of ionizing radiation, and the treatment of cancer patients with radiation. After completion of this training, a radiation oncologist may undergo certification by the American Board of Radiology (ABR). Board certification includes three written tests and an oral examination which is given only once per year. The written tests include separate exams in radiation physics, and radiobiology (between the 4th and 5th years), clinical oncology (after the completion of residency), which is followed by an eight-part oral examination given in the late spring one year into practice. Successfully passing these tests leads to the granting of a time-limited board certification. Recertification is obtained via a series of continuing medical education and practice qualifications including a written exam, clinical practice parameter evaluation, continuing medical education credits, and meeting community practice standards.

India

Radiotherapy training in India encompasses the treatment of solid tumors in terms of Chemotherapy, radiation therapy, and palliative care in most states. Postgraduate MD degree is awarded after 3 years of post-MBBS in-service comprehensive training and a final university level exam. MD Radiation oncology practitioners are the most proficient oncologists in India delivering radiotherapy and chemotherapy. The first Radiotherapy department of Asia was set up in 1910 at Calcutta Medical College in the state of West Bengal and is still a leading oncology training center of India.

Canada

Radiation Oncology training in Canada is very similar to the United States. Radiation oncologists directly enter radiation oncology residencies of 5 years duration, with the first year as an internship year. During the next four years, residents complete intensive training in clinical oncology, in radiophysics and radiobiology, and in the treatment planning and delivery of radiotherapy. Most radiation oncologists also pursue a fellowship after their residency, examples of which include brachytherapy, intensity modulated radiation therapy (IMRT), gynecologic radiation oncology, and many others. Radiation oncologists in Canada commonly treat two or three different anatomic sites, such as head and neck, breast, genitourinary, hematologic, gynecologic, central nervous system, or lung cancer.

United Kingdom & Ireland

In the United Kingdom, clinical oncologists, who practise radiotherapy are also fully qualified to administer chemotherapy. After completion of their basic medical degree, all oncologists must train fully in general internal medicine and pass the MRCPexam, normally 3–4 years after qualification. Following this, 5 years of Specialist Registrar (SpR) training is required in all non-surgical aspects of oncology in a recognised training program. During this time, the trainee must pass the FRCRexamination in order to qualify for specialist registration as a clinical oncologist. A significant proportion of trainees will extend their time to undertake an academic fellowship, MD, or PhD. Almost all consultant clinical oncologists in the UK are Fellows of the Royal College of Radiologists, the governing body of the specialty. Whilst most oncologists will treat a selection of common general oncology cases, there is increasing specialisation, with the expectation that consultants will specialise in one or two subsites.

Australia and New Zealand

In Australia and New Zealand, The Royal Australian and New Zealand College of Radiologists (RANZCR [1]) awards a Fellowship (FRANZCR) to trainees after a 5-year program and several sets of exams and modules. As in other countries, radiation oncologists tend to subspecialize although generalists will always exist in smaller centres. Although trained in the delivery of chemotherapy, radiation oncologists in Australia and New Zealand rarely prescribe it.

Iran

In Iran, radiation oncologists, who are trained in non-surgical aspects of oncology (including radiation therapy) directly enter a 5-year residency program after completion of 7 years of training in general medicine and acceptance in national comprehensive residency exam.

Nepal

In Nepal, only Bir Hospital runs residency program on Radiation Oncology, under NAMS. It's a 3 years residency program, and the main domains are Chemotherapy, Radiotherapy and Palliative Care.
