Clinical target volume delineation including elective nodal irradiation in preoperative and definitive radiotherapy of pancreatic cancer
BACKGROUND Radiotherapy (RT) is widely used in the treatment of pancreatic cancer. Currently, recommendation has been given for the delineation of the clinical target volume (CTV) in adjuvant RT. Based on recently reviewed pathologic data, the aim of this study is to propose criteria for the CTV definition and delineation including elective nodal irradiation (ENI) in the preoperative and defini...
متن کاملUniformity of Dose Distribution in Target Volume in Radiotherapy Techniques for Breast after Mastectomy.
Background & Objective: Radiotherapy has a very special significance in the treatment of cancer. Beam radiation therapy using photons and electrons produced by a linear accelerator is used extensively in the treatment of breast Cancer. In this article, In addition to providing a description of three techniques of radiotherapy in the treatment of breast cancer, has been Evaluating the effectiven...
متن کاملOptimization of clinical target volume delineation using magnetic resonance spectroscopic imaging (MRSI) in 3D conformal radiotherapy of prostate cancer
Background: For the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, MRSI was used as a molecular imaging modality with MRI and CT images. Materials and Methods: The images of 20 prostate cancer patients were used in this study. The MR and MRSI images were registered with CT ones using non-rigid registration technique. The CT based planning (BP), CT/MR...
متن کاملRadiotherapy planning for glioblastoma based on a tumor growth model: improving target volume delineation.
Glioblastoma differ from many other tumors in the sense that they grow infiltratively into the brain tissue instead of forming a solid tumor mass with a defined boundary. Only the part of the tumor with high tumor cell density can be localized through imaging directly. In contrast, brain tissue infiltrated by tumor cells at low density appears normal on current imaging modalities. In current cl...
متن کاملGlioblastoma growth modeling for radiotherapy target delineation
Radiotherapy treatment planning requires a localization of the tumor within the patient. This is challenging to accomplish for microscopic infiltrative spread of disease that is not visible on current imaging modalities. Prime examples for infiltrative tumors are gliomas. With the help of mathematical models, common growth characteristics of gliomas, which are known from histopathological studi...
