Intraoperative radiotherapy (IORT) combined with external beam radiotherapy (EBRT) for soft-tissue sarcomas – a retrospective evaluation of the Homburg experience in the years 1995–2007
Radiation Oncology - Tập 4 - Trang 1-6 - 2009
Marcus Niewald, Jochen Fleckenstein, Norbert Licht, Caroline Bleuzen, Christian Ruebe
To retrospectively evaluate the results after a regimen of surgery, IORT (intraoperative radiotherapy), and EBRT (external beam radiotherapy) for soft-tissue sarcomas 38 consecutive patients underwent IORT for soft-tissue sarcoma; 29 were treated for primary tumours, 9 for recurrences. There were 14 cases with liposarcomas, 8 with leiomyosarcomas, 7 with malignant fibrous histiocytomas. 27/38 tumo...... hiện toàn bộ
Intrafractional dose variation and beam configuration in carbon ion radiotherapy for esophageal cancer
Radiation Oncology - Tập 11 - Trang 1-9 - 2016
M. F. Haefner, F. Sterzing, D. Krug, S. A. Koerber, O. Jaekel, J. Debus, M. M. Haertig
In carbon ion radiotherapy (CIR) for esophageal cancer, organ and target motion is a major challenge for treatment planning due to potential range deviations. This study intends to analyze the impact of intrafractional variations on dosimetric parameters and to identify favourable settings for robust treatment plans. We contoured esophageal boost volumes in different organ localizations for four p...... hiện toàn bộ

Modern radiation therapy and potential fertility preservation strategies in patients with cervical cancer undergoing chemoradiation
Radiation Oncology - Tập 10 - Trang 1-6 - 2015
Pirus Ghadjar, Volker Budach, Christhardt Köhler, Andreas Jantke, Simone Marnitz
Young patients with cervical cancer who undergo chemoradiation might be interested in fertility preservation, not only dependent upon the use of a gestational carrier as maybe achieved by the use of ovarian transposition and cryo-conservation of oocytes or ovarian tissue, but may prefer to carry pregnancy to term after cancer treatment. The latter approach is a non-established concept needing both...... hiện toàn bộ
High-dose stereotactic body radiotherapy using CyberKnife® for stage I peripheral lung cancer: a single-center retrospective study
Radiation Oncology - Tập 17 Số 1 - 2022

Abstract Background This retrospective study was performed to evaluate the efficacy and toxicity of high-dose stereotactic body radiotherapy (SBRT) using a CyberKnife® for patients with stage I peripheral non-small cell lung cancer (NSCLC). ...... hiện toàn bộ
Excluding the ischiorectal fossa irradiation during neoadjuvant chemoradiotherapy with intensity-modulated radiotherapy followed by abdominoperineal resection decreases perineal complications in patients with lower rectal cancer
Radiation Oncology - Tập 14 - Trang 1-11 - 2019
Maxiaowei Song, Jianhao Geng, Lin Wang, Yongheng Li, Xianggao Zhu, Xiaofan Li, Lan Mi, Aiwen Wu, Yifan Peng, Yunfeng Yao, Yangzi Zhang, Hongzhi Wang, Chen Shi, Yong Cai, Weihu Wang
The aim of this study was to explore the impact of including or excluding the ischiorectal fossa (IRF) within the clinical target volume during neoadjuvant chemoradiotherapy (NCRT) using intensity modulated radiotherapy, in locally advanced lower rectal cancer (LALRC). We retrospectively analysed the data of 220 LALRC patients who received NCRT followed by abdominoperineal resection between Januar...... hiện toàn bộ
Reirradiation as part of a salvage treatment approach for progressive non-pontine pediatric high-grade gliomas: preliminary experiences from the German HIT-HGG study group
Radiation Oncology - Tập 9 - Trang 1-8 - 2014
Klaus Müller, Heike Scheithauer, Sophie Pietschmann, Marion Hoffmann, Jochen Rössler, Norbert Graf, Brigitta G Baumert, Hans Christiansen, Rolf-Dieter Kortmann, Christof M Kramm, André O von Bueren
The aim of the present analysis was to assess the feasibility, toxicity, and the tumor control of reirradiation as a salvage treatment for progressive pediatric non-pontine high-grade gliomas (HGG). The database of the Reference Center for Radiation Oncology of the German HIT (HIT = German acronym for brain tumor) treatment network for childhood brain tumors was screened for children who were reir...... hiện toàn bộ
Characteristics of non-coplanar IMRT in the presence of target-embedded organs at risk
Radiation Oncology - Tập 10 - Trang 1-14 - 2015
Klaus Bratengeier, Kostyantyn Holubyev
The aim is to analyze characteristics and to study the potentials of non-coplanar intensity modulated radiation therapy (IMRT) techniques. The planning study applies to generalized organ at risk (OAR) – planning target volume (PTV) geometries. The authors focus on OARs embedded in the PTV. The OAR shapes are spherically symmetric (A), cylindrical (B), and bended (C). Several IMRT techniques are us...... hiện toàn bộ
Target volume definition in high-risk prostate cancer patients using sentinel node SPECT/CT and 18 F-choline PET/CT
Radiation Oncology - Tập 7 - Trang 1-7 - 2012
Hansjörg Vees, Charles Steiner, Giovanna Dipasquale, Amine Chouiter, Thomas Zilli, Michel Velazquez, Sophie Namy, Osman Ratib, Franz Buchegger, Raymond Miralbell
To assess the influence of sentinel lymph nodes (SNs) SPECT/CT and 18 F-choline (18 F-FCH) PET/CT in radiotherapy (RT) treatment planning for prostate cancer patients with a high-risk for lymph node (LN) involvement. Twenty high-risk prostate cancer patients underwent a pelvic SPECT acquisition following a transrectal ultrasound guided injection of 99mTc-Nanocoll into the prostate. In all patients...... hiện toàn bộ
Cervical necrosis after chemoradiation for cervical cancer: case series and literature review
Radiation Oncology - - 2013
Z.S. Fawaz, Maroie Barkati, Marie-Claude Beauchemin, Philippe Sauthier, Philippe Gauthier, Thu Van Nguyen
Abstract Background The aim of this study was to assess the management of cervical necrosis (CN) following radiotherapy (RT) and the impact of smoking status. This rare complication mimics a neoplastic recurrence, and causes concern among attending physicians. ...... hiện toàn bộ
