Radiation Therapy News and Research

RSS

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

Children with low-risk retinoblastoma do not need postoperative chemotherapy

New results from a prospective clinical trial conducted in France show that children with low-risk retinoblastoma do not need postoperative (adjuvant) chemotherapy to prevent disease recurrence or metastasis; the results also suggest that certain patients with intermediate-risk disease can receive less aggressive adjuvant treatment, or perhaps forego it altogether. Avoiding chemotherapy spares patients from treatment side effects and long-term health risks, such as cardiovascular disease and development of a second cancer.
