Purpose: To retrospectively compare dosimetrically three dimensional field-in-field tangents (3D F-in-F), Intensity modulated radiotherapy (IMRT) and volumetric arc therapy (VMAT) left breast irradiation plans. Materials Methods: A total of 30 patients were included in this study. All diagnosed with early–stage malignant neoplasm the prior to treatment. Patients contoured main PTV-Chest wall (P...
Introduction: We aimed to dosimetrically compare three-dimensional conformal radiotherapy (3D-CRT) and volumetric modulated arc therapy (VMAT) in terms of planning target volume (PTV) coverage, organ at risk (OAR) sparing, and conformity index (CI). Material and Methods: Planning data of 26 high grade glioma (HGG) patients were used. Prescrib...
BACKGROUND Lung cancer patients are often in poor physical condition, and a shorter treatment time would reduce their discomfort. Dynamic conformal arc therapy (DCAT) offers a shorter treatment time than conventional 3D conformal radiotherapy (3D CRT) and is usually available even in departments without inverse planning possibilities. We examined its suitability as a treatment modality for lung...
Abstract Objective To compare volumetric modulated arc therapy (VMAT) with simultaneous tumor bed boost (dpSIB‐VMAT) to the whole breast and regional nodal irradiation (RNI) against standard three‐dimensional conformal radiotherapy plus RNI sequential (3D‐CRT‐seqB). Methods Thirty patients who underwent cancer surgery (BCS) axillary lymph node dissection (ALND) were enrolled. Two plans generate...
We propose a comparative dosimetric study of whole-breast hypofractionated radiation therapy using helical tomotherapy (HT) in supine position and 3-D conformal radiotherapy (3D-CRT) in prone position. Twelve patients undergoing breast-conserving therapy were retrospectively selected from October to December 2012. Specific dose-volume parameters were selected for the study. The target coverage ...
Introduction: Hypothyroidism is one of the frequent side effects of radiotherapy of head and neck cancers, breast cancer, and Hodgkin's lymphoma. It is recommended to estimate the normal tissue complication probability of thyroid gland using radiobiological modeling during treatment planning. Moreover, the use of artificial neural network is also proposed as a new method for t...
Objective Intensity-modulated radiation therapy (IMRT) has largely supplanted three-dimensional conformal radiation (3D-CRT) for definitive anal cancer treatment due to decreased toxicity and potentially improved outcomes. Convincing data demonstrating its advantages, however, remain limited. We compared outcomes and toxicity with concurrent chemotherapy and IMRT vs 3D-CRT for anal cancer. Me...
"Purpose: Whole breast radiation therapy (WBRT) with a boost to the tumor bed following con-servative primary surgery in women cancer (BC) plays central role reducing local recurrences and mortality. Volumetric modulated arc (VMAT) technique has been shown allow better dose conformation low levels organs at risk (OARs), compared static fields three-dimensional Conformal Radiotherapy (3D-CRT). T...
Introduction: Breast cancer is the most common cancer among women. Radiotherapy plays an important role in the treatment of breast cancer and essential part of the standard treatment after breast-conserving surgery, routinely done to eliminate the microscopic residual cancer. The heart and lungs are one of the most important organs at risk of breast cancer radiotherapy that th...
The aim of this study was to compare the dosimetric parameters of whole-pelvic radiotherapy (WPRT) for cervical cancer among plans involving 3D conformal radiotherapy (3D-CRT), intensity-modulated radiotherapy (IMRT), or spot-scanning proton therapy (SSPT). The dose distributions of 3D-CRT-, IMRT-, and SSPT-based WPRT plans were compared in 10 patients with cervical cancer. All of the patients ...
