Strahlentherapie und Onkologie > 2019 > 195 > 3 > 226-235

Background The dosimetric variability in spine stereotactic body radiation therapy (SBRT) planning was investigated in a large number of centres to identify crowd knowledge-based solutions. Methods Two spinal cases were planned by 48 planners (38 centres). The required prescription dose (PD) was 3 × 10 Gy and the planning target volume (PTV) coverage request was: V_PD > 90% (minimum request: V...

Medical Oncology > 2018 > 35 > 12 > 1-11

The aim of the study is to evaluate feasibility, safety, toxicity profile, and dosimetric results of volumetric modulated arc therapy (VMAT) to deliver definitive or pre-operative radiation in locally advanced esophageal cancer patients. A total of 68 patients were treated with VMAT between March 2014 and March 2018 (44% vs 56% for definitive and neoadjuvant settings, respectively). Dose prescription...

Physica Medica > 2018 > 52 > S1 > 157

To investigate the accuracy and robustness of commercial algorithms for Deformable Image Registration (DIR) to propagate regions of interest (ROIs), against image quality typical of Cone Beam CT (CBCT) and Megavoltage Cone-beam CT (MVCT) images, using computational phantoms based on real head and neck (HN) patient images.Eleven institutions joined the study with five commercial DIR solutions. Three...

Evaluation of dose recalculation vs dose deformation in a commercial platform for deformable image registration with a computational phantom

Marco Fusella, Francesca R. Giglioli, Christian Fiandra, Riccardo Ragona

Medical Dosimetry > 2018 > 43 > 1 > 82-90

Deformable image registration (DIR) is an important tool for mapping both dose and contours of a new set of planning images when recurrent, that is, adaptive radiotherapy, or further treatment, that is, re-treatment, is required. The aim of this study was to evaluate the need for plan recalculation in deformed anatomies and to develop a reliable workflow for validating the DIR algorithm to be applied...

Frontiers in planning optimization for lung SBRT

Francesca Romana Giglioli, Stefania Clemente, Marco Esposito, Christian Fiandra, more

Physica Medica > 2017 > 44 > C > 163-170

Emerging data are showing the safety and the efficacy of Stereotactic Body Radiation therapy (SBRT) in lung cancer management. In this context, the very high doses delivered to the Planning Target Volume, make the planning phase essential for achieving high dose levels conformed to the shape of the target in order to have a good prognosis for tumor control and to avoid an overdose in relevant healthy...

Incorporating ¹⁸FDG-PET-defined pelvic active bone marrow in the automatic treatment planning process of anal cancer patients undergoing chemo-radiation

Pierfrancesco Franco, Christian Fiandra, Francesca Arcadipane, Elisabetta Trino, more

BMC Cancer > 2017 > 17 > 1 > 1-11

Background To investigate whether the incorporation of ¹⁸FDG-PET into the automatic treatment planning process may be able to decrease the dose to active bone marrow (BM) for locally advanced anal cancer patients undergoing concurrent chemo-radiation (CHT-RT). Methods Ten patients with locally advanced anal cancer were selected. Bone marrow within the pelvis was outlined as the whole outer contour...

Small field output factors evaluation with a microDiamond detector over 30 Italian centers

Serenella Russo, Giacomo Reggiori, Elisabetta Cagni, Stefania Clemente, more

Physica Medica > 2016 > 32 > 12 > 1644-1650

The aim of the study was a multicenter evaluation of MLC&jaws-defined small field output factors (OF) for different linear accelerator manufacturers and for different beam energies using the latest synthetic single crystal diamond detector commercially available. The feasibility of providing an experimental OF data set, useful for on-site measurements validation, was also evaluated.This work was...

Multiinstitutional national study for planning comparison on different anatomical sites

Carmelo Marino, Elisa Bonanno, Giuseppina R. Borzı̀, Laura Bottalico, more

Physica Medica > 2016 > 32 > S3 > 178

The SBRT working group of Italian Association of Medical Physics (AIFM) performed 4 multicenter planning studies on patients who were candidates for SBRT in the treatments of prostate, liver, lung and spine cancer with the aim of evaluating the dosimetric consistency among the different hospitals.Plans were performed following the dose prescription of 35Gy in five fractions for the planning target...

Lung stereotactic ablative body radiotherapy: A large scale multi-institutional planning comparison for interpreting results of multi-institutional studies

Francesca Romana Giglioli, Lidia Strigari, Riccardo Ragona, Giuseppina R. Borzì, more

Physica Medica > 2016 > 32 > 4 > 600-606

A large-scale multi-institutional planning comparison on lung cancer SABR is presented with the aim of investigating possible criticism in carrying out retrospective multicentre data analysis from a dosimetric perspective.Five CT series were sent to the participants. The dose prescription to PTV was 54Gy in 3 fractions of 18Gy. The plans were compared in terms of PTV-gEUD₂ (generalized Equivalent...

Optimized Volumetric Modulated Arc Therapy Versus 3D-CRT for Early Stage Mediastinal Hodgkin Lymphoma Without Axillary Involvement: A Comparison of Second Cancers and Heart Disease Risk

Andrea Riccardo Filippi, Riccardo Ragona, Cristina Piva, Davide Scafa, more

International Journal of Radiation Oncology, Biology, Physics > 2015 > 92 > 1 > 161-168

The purpose of this study was to evaluate the risks of second cancers and cardiovascular diseases associated with an optimized volumetric modulated arc therapy (VMAT) planning solution in a selected cohort of stage I/II Hodgkin lymphoma (HL) patients treated with either involved-node or involved-site radiation therapy in comparison with 3-dimensional conformal radiation therapy (3D-CRT).Thirty-eight...

Purpose Hodgkin lymphoma (HL) is a highly curable disease. Reducing late complications and second malignancies has become increasingly important. Radiotherapy target paradigms are currently changing and radiotherapy techniques are evolving rapidly. Design This overview reports to what extent target volume reduction in involved-node (IN) and advanced radiotherapy techniques, such as intensity-modulated...

Practical Radiation Oncology > 2013 > 3 > 3 > 216-222

The contribution of thoracic radiation in increasing secondary breast cancer (BC) risk in female Hodgkin lymphoma patients is well known, and recent changes in radiation therapy volumes, doses and techniques are supposed to minimize it. In this study, we compared different radiation therapy solutions in terms of secondary BC induction risk with the aim of selecting which could be considered the most...
