Survival of tumor cells after proton irradiation with ultra-high dose rates
Radiation Oncology - Tập 6 Số 1 - 2011
Susanne Auer, V. Hable, C. Greubel, G. Drexler, Thomas E. Schmid, Claus Belka, G. Dollinger, Anna A. Friedl
Abstract Background Laser acceleration of protons and heavy ions may in the future be used in radiation therapy. Laser-driven particle beams are pulsed and ultra high dose rates of >109 Gy s-1may be achieved. Here we compare the radiobiological effects...... hiện toàn bộ
Outcomes and patterns of care of patients with locally advanced oropharyngeal carcinoma treated in the early 21st century
Radiation Oncology - Tập 8 - Trang 1-10 - 2013
Adam S Garden, Merrill S Kies, William H Morrison, Randal S Weber, Steven J Frank, Bonnie S Glisson, Gary B Gunn, Beth M Beadle, K Kian Ang, David I Rosenthal, Erich M Sturgis
We performed this study to assess outcomes of patients with oropharyngeal cancer treated with modern therapy approaches. Demographics, treatments and outcomes of patients diagnosed with Stage 3- 4B squamous carcinoma of the oropharynx, between 2000 – 2007 were tabulated and analyzed. The cohort consisted of 1046 patients. The 5- year actuarial overall survival, recurrence-free survival and local-r...... hiện toàn bộ
Regression models for predicting physical and EQD2 plan parameters of two methods of hybrid planning for stage III NSCLC
Radiation Oncology - Tập 16 - Trang 1-13 - 2021
Hao Wang, Yongkang Zhou, Wutian Gan, Hua Chen, Ying Huang, Yanhua Duan, Aihui Feng, Yan Shao, Hengle Gu, Qing Kong, Zhiyong Xu
To establish regression models of physical and equivalent dose in 2 Gy per fraction (EQD2) plan parameters of two kinds of hybrid planning for stage III NSCLC. Two kinds of hybrid plans named conventional fraction radiotherapy & stereotactic body radiotherapy (C&S) and conventional fraction radiotherapy & simultaneous integrated boost (C&SIB) were retrospectively made for 20 patients with stage II...... hiện toàn bộ
Hippocampal sparing radiotherapy for glioblastoma patients: a planning study using volumetric modulated arc therapy
Radiation Oncology - Tập 11 - Trang 1-8 - 2016
Jan Hofmaier, Steffi Kantz, Matthias Söhn, Oliver S. Dohm, Stefan Bächle, Markus Alber, Katia Parodi, Claus Belka, Maximilian Niyazi
The purpose of this study is to investigate the potential to reduce exposure of the contralateral hippocampus in radiotherapy for glioblastoma using volumetric modulated arc therapy (VMAT). Datasets of 27 patients who had received 3D conformal radiotherapy (3D-CRT) for glioblastoma with a prescribed dose of 60Gy in fractions of 2Gy were included in this planning study. VMAT plans were optimized wi...... hiện toàn bộ
Simultaneous integrated boost therapy of carcinoma of the hypopharynx/larynx with and without flattening filter - a treatment planning and dosimetry study
Radiation Oncology - Tập 12 - Trang 1-9 - 2017
Barbara Dobler, Tina Obermeier, Matthias G. Hautmann, Amine Khemissi, Oliver Koelbl
The aim of this study was to investigate if the flattening filter free (FFF) irradiation mode of a linear accelerator (linac) is advantageous as compared to the flat beam (FF) irradiation mode in intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) for carcinoma of the hypopharynx / larynx. Four treatment plans were created for each of 10 patients for an Elekta ...... hiện toàn bộ
Association between the location of transposed ovary and ovarian dose in patients with cervical cancer treated with postoperative pelvic radiotherapy
Radiation Oncology - Tập 14 - Trang 1-9 - 2019
Xiao-juan Lv, Xiao-long Cheng, Ye-qiang Tu, Ding-ding Yan, Qiu Tang
How to protect the ovarian function during radiotherapy is uncertain. The purpose of this study was to explore the association between the location of the transposed ovary and the ovarian dose in patients with cervical cancer received radical hysterectomy, ovarian transposition, and postoperative pelvic radiotherapy. A retrospective analysis was conducted of 150 young patients with cervical cancer...... hiện toàn bộ
Stereotactic body radiotherapy for metastatic sarcoma to the lung: adding to the arsenal of local therapy
Radiation Oncology - Tập 18 - Trang 1-7 - 2023
Paulina M. Gutkin, Elizabeth Gore, John Charlson, John C. Neilson, Candice Johnstone, David M. King, Donald A. Hackbarth, Adam Wooldridge, Rajeev Mannem, Meena Bedi
Conventional treatment of pulmonary metastatic sarcoma primarily involves surgery, with systemic therapy added in select patients. However, broader applications of radiation therapy techniques have prompted investigation into the use of stereotactic body radiotherapy (SBRT) for treatment of metastatic sarcoma, an attractive non-invasive intervention with potential for lower rates of adverse events...... hiện toàn bộ
Neoadjuvant radiotherapy improves overall survival for T3/4N+M0 rectal cancer patients: a population-based study of 20300 patients
Radiation Oncology - Tập 15 - Trang 1-11 - 2020
Feng Zhao, Jili Wang, Hao Yu, Xiaofei Cheng, Xinke Li, Xuan Zhu, Xiangming Xu, Jianjiang Lin, Xin Chen, Senxiang Yan
Neoadjuvant radiotherapy (RT) has been shown to improve local control; however, whether it can improve overall survival (OS) in locally advanced rectal cancer (LARC) patients remains controversial. We therefore aimed to examine the benefits of surgery alone, neoadjuvant radiotherapy (RT), adjuvant RT, and surgery plus chemotherapy in stage II (T3/4N0M0) and III (any T and N + M0) on the OS of rect...... hiện toàn bộ
Circulating miR-21 as a prognostic biomarker in HCC treated by CT-guided high-dose rate brachytherapy
Radiation Oncology - Tập 18 Số 1 - Trang 1-11 - 2023
Stechele, Matthias, Link, Henrike, Hirner-Eppeneder, Heidrun, Alunni-Fabbroni, Marianna, Wildgruber, Moritz, Salvermoser, Lukas, Corradini, Stefanie, Schinner, Regina, Ben Khaled, Najib, Rössler, Daniel, Galun, Eithan, Goldberg, Shraga Nahum, Ricke, Jens, Kazmierczak, Philipp Maximilian
Prognostic biomarkers identifying patients with early tumor progression after local ablative therapy remain an unmet clinical need. The aim of this study was to investigate circulating miR-21 and miR-210 levels as prognostic biomarkers of HCC treated by CT-guided high-dose rate brachytherapy (HDR-BT). 24 consecutive HCC patients (BCLC A and B) treated with CT-guided HDR-BT (1 × 15 Gy) were in...... hiện toàn bộ
