Background. The benefits of proton beam craniospinal irradiation (PrBCSI) in children have been extensively reported dosimetric studies. However, there is limited clinical evidence supporting the use PrBCSI. We compared acute toxicity PrBCSI relative to that conventional photon CSI (PhBCSI) with brain tumours.Material and methods. prospectively evaluated haematological gastrointestinal toxicities 30 patients who underwent between April 2008 December 2012. As a reference group, we...
The purpose of this report is to describe the proton therapy system at Samsung Medical Center (SMC-PTS) including beam generator, irradiation system, patient positioning position verification respiratory gating and operating safety control review current status SMC-PTS.The SMC-PTS has a cyclotron (230 MeV) two treatment rooms: one room equipped with multi-purpose nozzle other dedicated pencil scanning nozzle. generator energy selection can lower protons down 70 MeV from maximum 230 MeV.The...
To analyze the treatment outcomes and effects of adjuvant radiotherapy (RT) in patients with synovial sarcoma (SS).The medical records 103 treated definitive surgery for SS, with/without RT, from August 1982 to July 2013 were reviewed retrospectively. The median age was 33 years (range, 5 72 y). most frequent tumor location extremities (79 patients, 77%). Seventy-five (73%) received RT 26 (25%) did not. dose 61.2 Gy 45 66.6 Gy).The follow-up period 5.4 0.2 31.0 5- 10-year overall survival...
Abstract Particle Identification (PID) plays a central role in associating the energy depositions calorimeter cells with type of primary particle flow oriented detector system. In this paper, we propose novel PID methods based on Residual Network (ResNet) architecture which enable training very deep networks, bypass need to reconstruct feature variables, and ensure generalization ability among various geometries detectors, classify electromagnetic showers hadronic showers. Using Geant4...
To compare the impact of postoperative chemoradiotherapy (CRT) versus adjuvant chemotherapy alone on recurrence and survival in patients with stage II III upper rectal cancer undergoing curative resection.From our institutional database, 190 who underwent primary resection between 2003 2010 for or were identified. None received preoperative CRT. Of these, 136 (the CTx group) 54 CRT group). The group had poorer prognostic features (pT4, pN2, poor differentiation, involved margin) compared...
To evaluate treatment outcome of patients with high risk locally advanced gastric cancer after postoperative chemoradiotherapy.Between May 2003 and 2012, thirteen who underwent chemoradiotherapy for resection margin involvement or adjacent structure invasion were retrospectively analyzed. Concurrent chemotherapy was administered in 10 patients. Median dose radiation 50.4 Gy (range, 45 to 55.8 Gy).The median follow-up duration surviving 48 months 5 108 months). The 5-year overall survival...
To investigate disease-free survival (DFS) and prognostic factors following the administration of postoperative (chemo)radiotherapy in patients with early-stage cervical cancers.The medical records 1,069 from 10 participating institutions were reviewed. Statistically clinically established considered as candidates for constructing prediction model. This model was validated, using bootstrapping to correct optimistic bias.The 5-year DFS rate 81.1%, a median follow-up period 59.6 months. The...
Purpose The objective of this study was to assess the effect postoperative radiotherapy on outcome esophageal cancer with microscopically positive resection margin by comparing results those patients negative margin. Materials and Methods Medical records 88 treated macroscopic followed for stage II or III squamous cell carcinoma esophagus from June 1984 March 2008 were reviewed. Twelve had received chemotherapy. Patients classified into two groups based status: (group A, n=66) B, n=22)....
Treatment of tonsil cancer, a subset oropahryngeal varies between surgery and radiotherapy. Well-designed studies in cancer have been rare it is still controversial which treatment optimal. This study aimed to assess the outcome failure patterns patients treated with either approaches.We retrospectively reviewed medical records 586 1998 2010 at 16 hospitals Korea. Two hundred one received radiotherapy chemotherapy (CRT), while 385 followed by and/or (SRT). Compared SRT group, receiving CRT...
Stereotactic ablative radiotherapy (SABR) is an effective emerging technique for early-stage non-small cell lung cancer (NSCLC). We investigated the current practice of SABR NSCLC in Korea.We conducted a nationwide survey by sending e-mails to all board-certified members Korean Society Radiation Oncology. The included 23 questions focusing on technical aspects and 18 seeking participants' opinions specific clinical scenarios use NSCLC. Overall, 79 radiation oncologists at 61/85 specialist...
e17527 Background: To retrospectively review the outcome of definitive hypofractionated 3-dimensional conformal radiotherapy (3D-CRT) alone in locally advanced non-small cell lung cancer (NSCLC) medically unfit to multimodality treatment. Methods: 102 patients with clinical stage IIB-III NSCLC received 3D-CRT from Jan 2002 Jul 2007. Among them, 37 were analyzed. The other 65 excluded due history another cancer, incomplete treatment or loss follow-up without severe RT-associated complication....
