The addition of radiation therapy (RT) to surgery in retroperitoneal sarcoma (RPS) remains controversial. We examined practice patterns in the use of RT for patients with RPS over time in a large, national cohort. Patients in the National Cancer Database (2004–2017) who underwent resection of RPS were included. Trends over time for proportions were calculated using contingency tables with Cochran-Armitage

Protocol of a phase II study to evaluate the efficacy and safety of deep-inspiration breath-hold daily online adaptive radiotherapy for centrally located lung tumours (PUDDING study) Radiat. Oncol. (IF 3.6) Pub Date : 2024-03-08 Noriko Kishi, Masahiro Yoneyama, Hiroyuki Inoo, Minoru Inoue, Hiraku Iramina, Akiyoshi Nakakura, Tomohiro Ono, Hideaki Hirashima, Takanori Adachi, Norimasa Matsushita, Makoto Sasaki, Takahiro Fujimoto, Mitsuhiro Nakamura, Yukinori Matsuo, Takashi Mizowaki
Centrally located lung tumours present a challenge because of their tendency to exhibit symptoms such as airway obstruction, atelectasis, and bleeding. Surgical resection of these tumours often requires sacrificing the lungs, making definitive radiotherapy the preferred alternative to avoid pneumonectomy. However, the proximity of these tumours to mediastinal organs at risk increases the potential

Consideration of image guidance in patterns of failure analyses of intensity-modulated radiotherapy for head and neck cancer: a systematic review Radiat. Oncol. (IF 3.6) Pub Date : 2024-03-05 Paul-Henry Mackeprang, Katarina Bryjova, Astrid E. Heusel, Dominik Henzen, Melissa Scricciolo, Olgun Elicin
Intensity-modulated radiation therapy (IMRT) is considered standard of care for head and neck squamous cell carcinoma (HNSCC). Improved conformity of IMRT and smaller margins, however, have led to concerns of increased rates of marginal failures. We hypothesize that while patterns of failure (PoF) after IMRT for HNSCC have been published before, the quality of patient positioning and image guided radiotherapy

Pretreatment patient-specific quality assurance prediction based on 1D complexity metrics and 3D planning dose: classification, gamma passing rates, and DVH metrics Radiat. Oncol. (IF 3.6) Pub Date : 2023-11-20 Liyuan Chen, Huanli Luo, Shi Li, Xia Tan, Bin Feng, Xin Yang, Ying Wang, Fu Jin
Highly modulated radiotherapy plans aim to achieve target conformality and spare organs at risk, but the high complexity of the plan may increase the uncertainty of treatment. Thus, patient-specific quality assurance (PSQA) plays a crucial role in ensuring treatment accuracy and providing clinical guidance. This study aims to propose a prediction model based on complexity metrics and patient planning

Previous researches have demonstrated that adaptive replanning during intensity-modulated radiation therapy (IMRT) could enhance the prognosis of patients with nasopharyngeal carcinoma (NPC). However, the delineation of replanning target volumes remains unclear. This study aimed to evaluate the feasibility of reducing target volumes through adaptive replanning during IMRT by analyzing long-term survival

(IF 3.6) Pub Date : 2023-11-08 Boldizsar Kovacs, Michael Mayinger, Stefanie Ehrbar, Debra Fesslmeier, Maiwand Ahmadsei, Lorraine Sazgary, Robert Manka, Hatem Alkadhi, Frank Ruschitzka, Firat Duru, Alexandros Papachristofilou, Christian Sticherling, Slawomir Blamek, Krzysztof S. Gołba, Matthias Guckenberger, Ardan M. Saguner, Nicolaus Andratschke
Stereotactic arrhythmia radioablation (STAR) is delivered with a planning target volume (PTV) prescription dose of 25 Gy, mostly to the surrounding 75–85% isodose line. This means that the average and maximum dose received by the target is less than 35 Gy, which is the minimum threshold required to create a homogenous transmural fibrosis. Similar to catheter ablation, the primary objective of STAR
