Full textThis thesis is focused on the predictive models of irradiation induced toxicities in intensity modulated radiotherapy. Six different NTCP models were implemented and their parameters were identified at predicting late rectal and bladder toxicities in prostate cancer. Their predictive skills have been demonstrated on both organs. Second, LKB model was used to predict the irradiation induced acute esophagitis after nun-small-cell lung cancer. Then, the benefit of using EUD in prostate cancer IMRT inverse planning was evaluated. The evaluation of the proposed approach proved that the use of EUD significantly decreased both the dose in the bladder and rectum walls. Then, the incorporation of different biological models in IMRT optimization process has been realized. Objective functions were established for different biological factors like NTCP, EUD and TCP. Obtained results show the superiority of the optimization based on biological factors over the optimization relying only on physical factors. Finally, classical NTCP models were corrected to deal with another radiobiological parameter, the α/β ratio. With this additional factor, NTCP models can be extended to predict toxicity for patients with different dose fractionation, these kinds of treatments being more and more clinically used

A Probabilidade de Complicação em Tecidos Normais (NTCP) e a Probabilidade de Controle do Tumor (TCP) são parâmetros fornecidos por Sistemas de Planejamentos de Tratamentos (TPS) computadorizados, usados na rotina da radioterapia que auxiliam na interpretação da qualidade do tratamento. Neste trabalho são analisados os planejamentos de radioterapia de 03 pacientes portadores de câncer de próstata. Os planejamentos dos tratamentos foram realizados no TPS XiO, simulando as técnicas de radioterapia por intensidade modulada de feixe (IMRT) e radioterapia tridimensional conformada (3D-CRT). A dose de radiação preconizada para o volume de tratamento planejado (PTV) foi de 7.600 cGy, as simulações foram realizadas para um arranjo de 6 campos de radiação com feixes de raios X de megavoltagem e energia de 10 MV. Os volumes prostáticos variaram entre 107 cm3 e 143 cm3. A dose de cobertura D98% do PTV variou de 6.940 cGy a 7.570 cGy com IMRT e de 6.410 cGy a 7.250 cGy com 3D-CRT. Os valores obtidos para o TCP ficaram entre 73,5% a 81,1% com IMRT e entre 70,6% a 75,9% com 3D-CRT. Considerando os valores de NTCP para o reto e a bexiga, os maiores valores encontrados foram 6,9% para o reto e 6,1% para a bexiga, ambos planejados com a técnica de 3D-CRT.

Abstract: The success of radiotherapy is closely related to the therapeutic ratio which represents the ratio of the amount of irradiated tumor tissue to the volume of healthy tissue achieved. Normal Tissue Complication Probability (NTCP) and Tumor Control Probability (TCP) are parameters provided by computerized treatment planning systems (TPS), used in radiotherapy routine and also allow the interpretation of treatment quality. The aim of this work is analyze the planning of 03 cases of patients submitted to prostate cancer radiotherapy. The treatment plans were performed in TPS XiO, simulating the techniques of beam intensity modulated radiotherapy (IMRT) and tree-dimensional conformal radiation therapy (3D-CRT). The recommended radiation dose for the planned treatment volume (PTV) was 7600 cGy, the simulations were performed for an arrangement of 6 radiation fields with megavoltage X-ray beams and 10 MV energy. Prostatic volumes ranged from 107cm3 to 143cm3 . The D98% PTV coverage dose ranged from 6,940 cGy to 7,570 cGy with IMRT and from 6,410 cGy to 7,250 cGy with 3D-CRT. The values obtained for TCP were between 73.5% to 81.1% with IMRT and between 70.6% to 75.9% with 3D-CRT. Considering the NTCP values for the rectum and bladder, the highest values found were 6.9% for the rectum and 6.1% for the bladder, both planned using the 3D-CRT technique. For the analyzed cases, the results show that the IMRT technique presents better NTCP and TCP values than the 3D-CRT technique. These par... (Complete abstract click electronic access below)
