Virtual bolus for total body irradiation treated with helical tomotherapy
Intensity-modulated radiation therapy (IMRT) for total body irradiation (TBI) is practiced in several centers using the TomoTherapy System. In this context the planning target volume (PTV) is the entire body including the skin. A safety margin in the air surrounding the body should be added to take into account setup errors. But using inverse planning, over-fluence peak could be generated in th...
متن کاملPredictive Factors for Radiation Pneumonitis in Lung Cancer Treated with Helical Tomotherapy
PURPOSE Predictive factors for radiation pneumonitis (RP) after helical tomotherapy (HT) may differ from those after linac-based radiotherapy. In this study, we identified predictive factors for RP in patients with lung cancer treated with HT. MATERIALS AND METHODS We retrospectively analyzed clinical, treatment-related and dosimetric factors from 31 patients with lung cancer treated with HT....
متن کاملPreliminary analysis of risk factors for late rectal toxicity after helical tomotherapy for prostate cancer
The purpose of this study is to examine risk factors for late rectal toxicity for localized prostate cancer patients treated with helical tomotherapy (HT). The patient cohort of this retrospective study was composed of 241 patients treated with HT and followed up regularly. Toxicity levels were scored according to the Radiation Therapy Oncology Group grading scale. The clinical and dosimetric p...
متن کاملJunctioning longitudinally adjacent PTVs with Helical TomoTherapy
Irradiation of longitudinally adjacent PTVs with Helical TomoTherapy (HT) may be clinically necessary, for example in treating a recurrent PTV adjacent to a previously-treated volume. In this work, the parameters which influence the cumulative dose distribution resulting from treating longitudinally adjacent PTVs are examined, including field width, pitch, and PTV location. In-phantom dose dist...
متن کاملSecondary Cutaneous Involvement in Follicular Diffuse Lymphoma Treated with Helical Tomotherapy
Non-Hodgkin's lymphoma is a complex heterogeneous group of disease entities that involves nodal and extranodal tissues. Cutaneous involvement can occur either as a primary or secondary in course of disease. Radiation therapy with either total body or localized treatments is often used for local control and symptom relief, depending on the target volume. We describe a 60-year-old male with a rem...
