EP-1428: Adaptive treatment planning in prostate radiotherapy

Radiobiological Model in Radiotherapy Planning for Prostate Cancer Treatment

Quantitative radiobiological models can be used to assess the optimum clinical outcome from sophisticated therapeutic modalities by calculating tumor control probability (TCP) and normal tissue complication probability (NTCP). In this study two 3D-CRT and an IMRT treatment plans were developed with an initial prescription dose of 60 Gy in 2 Gy/fraction to prostate. Sensitivity of TCP and Compli...

A semiautomatic tool for prostate segmentation in radiotherapy treatment planning

BACKGROUND Delineation of the target volume is a time-consuming task in radiotherapy treatment planning, yet essential for a successful treatment of cancers such as prostate cancer. To facilitate the delineation procedure, the paper proposes an intuitive approach for 3D modeling of the prostate by slice-wise best fitting ellipses. METHODS The proposed estimate is initialized by the definition...

Radiotherapy treatment planning

In radical radiotherapy treatment we aim to accurately deliver a lethal dose of radiation to tumour cells while sparing any surrounding normal tissues. Radiotherapy treatment planning is the process undertaken to determine the most appropriate way to deliver the radiation in order to meet the clinical prescription. Rapid advances in technology and computing, particularly in relation to imaging,...

Advances in Radiotherapy for Prostate Cancer Treatment

Prostate cancer is one of the most common cancers in men, and there are a number of management options for localized disease, such as active surveillance, radical prostatectomy, chemotherapy, intensity-modulated radiotherapy, radiofre-quency ablation, cryotherapy, stereotactic ablative radiother-apy, particle therapy, brachytherapy, and an emerging range of focal therapies. Among these options,...
