Introduction of the Department of Radiation Oncology
 
The Department of Radiation Oncology (DRO) was founded in 1964 as an important department in cancer center, Sun Yat-Sen University. Since its inception, the department has maintained its position as a national leader in providing expert, prompt cancer care, high quality teaching and research. DRO is now one of the important medical special departments in Guangdong Province, with Masterate and Doctorate programs of Sun Yat-Sen University.
 
There is a professional team of 209 scientists including physicians, engineers, medical physicists, technicians, and nurses. The department consists of one outpatient section and four inpatient section of wards, with 186 ward beds in total. More than 4,500 patients were being treated annually in DRO. By combining radiotherapy with chemotherapy, surgery, biological therapy and other treatments, the survival of cancer patients has been greatly improved.

Cancer care
 
The department of Radiation Oncology consists of three divisions: clinical radiation oncology, radiation physics and radiation biology.
 
  1. Clinical radiation oncology
Radiotherapy effectively treats cancer by using high-energy beams to pinpoint and destroy cancerous cells. Over 60% of cancer patients will undergo radiation therapy; for some, it will be the only cancer treatment they need. Radiation is often used in combination with other treatments, including chemotherapy, surgery, etc. Used before or during other procedures, radiation can shrink the tumor to make surgery or chemotherapy more effective. Used afterward, it can destroy any cancer cells that might remain.
 
There are 53 physicians in DRO, including 12 professors, 15 associate professors, 20 attending physicians, and 6 residents. The department consists of 3 districts: nasopharyngeal carcinoma (NPC), the head and neck cancer, and cancer of the thorax, abdomen and pelvic cavity. There are about 650 patients to be managed every day. The most common cancers are NPC, head and neck cancer, gynecologic cancer, lung cancer, esophageal cancer, breast cancer, rectal cancer, and malignant lymphoma, etc. About 2,500 patients with NPC were being treated annually in our department, which accounting for the overwhelming majority (55% to 60%) of the total malignant neoplasm.
 
In the recent years, the department has standardized the radiotherapy principles of common malignancies, introduced new therapeutic technique and begun the modern precise radiotherapy. Many radiation techniques are available, such as 3DCRT, IMRT, 4DCT, IGRT and VMAT. About half of the patients are treated with 3DCRT or IMRT.

  2. Radiation physics
DRO has 29 engineers and physicists. The department of radiation physics (1) provides research-driven, safe, accurate and high quality patient care in collaboration with radiation oncologists, (2) conducts research and technology development to advance the state of the art and (3) provides education on the scientific (physics) and technical aspects of radiation oncology.
 
The most important function of the department of radiation physics is to provide quality assurance of imaging and treatment delivery equipment and of systems and processes to ensure optimal, accurate and safe delivery of treatments.
 
  3. Radiation biology
Radiation biological research in our department encompasses cellular, molecular, genetic and tissue micro-environmental aspects of the biology of neoplastic- and normal-tissue interactions with ionizing radiation and other cytotoxic agents. A better understanding of the mechanisms underlying these interactions is essential for improving radiotherapy.
 
Investigations in the area of cellular and molecular radiobiology are directed toward the basic mechanisms governing cellular radiosensitivity. Particular emphasis is placed on identifying mechanisms that control cell and tissue responses to radiation, intercellular mediation by cytokines, the cell-division cycle, and the propensity to undergo programmed cell death (apoptosis). New molecular assays are being developed to predict patient response to radiation using DNA-repair parameters.
