Kristina Tomlin Program - Radiotherapy has been and remains one of the main ways of dealing with cancer, along with chemotherapy and surgery. In developed countries, one in two cancer patients undergoing radiotherapy at some stage of the disease, Radiation therapy is highly effective against primary tumors, reducing local recurrence, increasing, possibly, survival and limiting the development of metastatic disease. It is also very effective in alleviating the symptoms of metastatic disease, in all patients who manage to survive cancer, it is estimated that 40% are cured thanks to radiotherapy either as sole therapy or as an essential component of treatment.
Kristina Tomlin Treatment One of the reasons why the radiation fails to control malignant tumors is difficult to deposit a lethal dose of radiation to the target area without harming the surrounding normal tissues. Objective of the radiation is the elimination of malignant cells with minimal morbidity. Conventional radiotherapy, since presented linear accelerators, developed the ability to cope with 'deep' malignant tumors.Kristina Tomlin Program Conventional beams were usually square or rectangular and inevitably included a substantial part of normal tissues. Normal tissues are more sensitive to radiation than the tumor cells. Therefore the tolerance of normal tissue is the limiting factor of the total dose, and therefore smaller dose deposited and to reduce the possibility of neutralizing the tumor. The maximum radiation dose that can be administered with the conventional technique is insufficient in most cases to control locally advanced disease.
Kristina Tomlin Program Combinations of various changing in intensity radiation beams are directed from different angles, in order to produce a customized and individualized dose maximizing radiation dose to the tumor while protecting adjacent normal tissues. Currently, the technique used for IMRT treatment of cancer in various sites such as prostate, head neck, thyroid, gynecological tumors, and others.”
