WebAbout this book. Basic Radiation Oncology is an all-in-one book, encompassing the essential aspects of radiation physics, radiobiology, and clinical radiation oncology. A complete section is devoted to each of these fields. In the first two sections, concepts that are crucial in radiation physics and radiobiology are reviewed in depth. WebFor organs at risk, GEC-ESTRO recommendations suggest reporting the dose for the most exposed 0.1 cc, 1.0 cc, and 2.0 cc (D0.1cc, D1cc, and D2cc), of the rectum, sigmoid, and bladder. As data regarding optimal treatment volumes evolve, recording the dose to point A (and taking care not to under dose point A) is still recommended.

WebIt is common practice in radiobiology to think of tumors as composed of radiosensitive aerobic cells and radioresistant hypoxic cells. This has been reinforced by measurements of the ‘hypoxic fraction’ using the paired survival curve method, by tumor regrowth delay and by tumor control (Moulder and Rockwell, 1984).This hypoxic fraction represents the fraction …
