ormal tissue damage is the most important limiting factor in radiotherapy. It must be possible, at least theoretically, to eradicate a localised tumour if a large enough dose of radiation could be delivered to tumour, however, practically, there is always the danger of damaging normal tissues adjacent to the tumour. Factors such as the total radiation dose, overall treatment time, dose per frac...
This paper describes the biological mechanisms of normal tissue reactions after radiation therapy, with reference to conventional treatments, new treatments, and treatments in developing countries. It also describes biological reasons for the latency period before tissue complications arise, the relationship of dose to incidence, the effect of increasing the size of the irradiated volume, early...
The importance of knowledge on tolerance of normal tissue organs to irradiation by radiation oncologists cannot be overemphasized. Unfortunately, current knowledge is less than adequate. With the increasing use of 3-D treatment planning and dose delivery, this issue, particularly volumetric information, will become even more critical. As a part of the NCI contract N01 CM-47316, a task force, ch...
A complex series of events involving inflammation, cell migration and proliferation, ECM stabilisation and remodelling, neovascularisation and apoptosis are crucial to the tissue response to injury. Wound healing involves the dynamic interactions of multiple cells types with components of the extracellular matrix (ECM) and growth factors. Impaired wound healing as a consequence of aging, injury...
Choristoma or heterotopias are sprengths of normal tissue cells in aberrant locations.
Cancer is one of the most difficult diseases to treat in modern medicine. Annually, many articles are published that propose various ways for preventing carcinogenesis. Furthermore, research into cancer treatments is carried out with minimal side effects. The most common non-invasive cancer treatments include chemotherapy, targeted therapy, radiotherapy, and immunotherapy. Low effectiveness of...
