To review treatment toxicity for patients with pancreatic and ampullary cancer treated proton therapy at our institution.From March 2009 through April 2012, 22 were concomitant capecitabine (1000 mg PO twice daily) resected (n = 5); marginally resectable unresectable/inoperable 12) biopsy-proven adenocarcinoma. Two unresectable disease excluded from the analysis reasons unrelated to treatment. Proton doses ranged 50.40 cobalt gray equivalent (CGE) 59.40 CGE.Median follow-up all was 11 (range...
With an increasing number of proton centers capable delivering pencil beam scanning (PBS), understanding the dosimetric differences in PBS compared to passively scattered therapy (PSPT) for pancreatic cancer is interest.Optimized plans were retrospectively generated 11 patients with locally advanced previously treated PSPT 59.4 Gy on a prospective trial. The primary tumor was targeted without elective nodal coverage. same treatment couch, target coverage and normal tissue dose objectives...
To assess the potential benefit of proton therapy (PT) over photon therapy, we compared 3-dimensional conformal radiotherapy (3DCRT), intensity-modulated (IMRT), and PT plans in patients undergoing neoadjuvant chemoradiation for resectable rectal cancer at our institution.Eight consecutive with (T2-T3) cancers underwent 3DCRT, IMRT, treatment planning. Initial target volumes (PTV1) were contoured using Radiation Therapy Oncology Group anorectal atlas guidelines. Boost (PTV2) consisted gross...
Background. Concurrent chemoradiotherapy (CRT) is the standard of care in patients with limited-stage small cell lung cancer (SCLC). Treatment conventional x-ray therapy (XRT) associated high toxicity rates, particularly acute grade 3+ esophagitis and pneumonitis. We present outcomes for first known series SCLC treated proton a dosimetric comparison esophageal doses intensity-modulated radiation (IMRT). Material methods. Six were treated: five concurrently one sequentially. Five received...
Our objective was to determine if protons allow for the expansion of treatment volumes cover high-risk nodes in patients with regionally advanced non-small-cell lung cancer. In this study, 5 consecutive underwent external-beam radiotherapy planning. Four plans were generated each patient: 1) photons (x-rays) treat positron emission tomography (PET)-positive gross disease only 74 Gy (XG); 2) 44 and PET-positive (XNG); 3) cobalt gray equivalent (PG); 4) CGE (PNG). We defined as mediastinal,...
Acetabular fractures can be treated with variable method. In this study, acetabular posterior wall fracture was arthroscopic reduction and fixation using cannulated screw. The patient recovered immediately had a satisfactory outcome. some case of could good indication additional advantages joint debridement loose body removal. So, we report our technical note.
In this case report, we present the history and treatment of a 70-year-old man with synchronous bilateral non-small-cell lung cancers proton-beam radiation. Surgical was not feasible optimized photon intensity-modulated radiotherapy (IMRT) to primary tumors would have resulted in unacceptably high normal-tissue exposures. Proton-beam radiation enabled dose escalation concurrent chemotherapy while maintaining tolerance.
Evaluate clinical outcomes in patients with vestibular schwannoma (VS) treated fractionated proton therapy (PT) at a single institution.We retrospectively reviewed the medical records of PT for definitive management VS between November 2007 and December 2013 our institution. No patient had received prior treatment VS. Patients 50.4 Gy 28 fractions using passively scattered PT. Pretreatment posttreatment hearing status, tumor dimensions, cranial nerve V VII function were evaluated. Hearing...
Background The treatment of centrally-located early-stage non-small cell lung cancer (NSCLC) with image-guided stereotactic body radiotherapy (SBRT) is challenging due to the proximity critical normal structures tumor target. purpose this study was report results our experience in treating NSCLC hypofractionated proton therapy (PT).Material and methods Between 2009 2018, 23 patients T1–T2N0M0 (T1, 46%; T2, 54%) were treated double-scattering PT. median age at time 74 years (range, 58–88)....
Evaluate the dosimetric impact of selective/elective nodal treatment with dose-escalated radiotherapy for regionally advanced non-small-cell lung cancer (NSCLC) using proton therapy (PT) or intensity-modulated (IMRT). Five consecutive patients NSCLC underwent planning high-dose involved-field (IF) (positron emission tomography-positive gross disease) without irradiation, defined as extended field (EF). Four plans were developed each patient: i) IMRT to treat IF 74 Gy (IFrT); ii) high-risk...
Background Although there are some controversies regarding whole pelvic radiation therapy (WPRT) due to its gastrointestinal and hematologic toxicities, it is considered for patients with gynecological, rectal, prostate cancer. To effectively spare organs-at-risk (OAR) doses using multi-leaf collimator (MLC)’s optimal segments, potential dosimetric benefits in volumetric modulated arc (VMAT) a half-beam technique (HF) were investigated WPRT. Methods While the size of fully opened field (FF)...
Purpose: CBCT and AlignRT are used as secondary imaging devices to setup a phantom with couch-mount stereotactic system. The geometrical accuracy of the radiosurgery system is investigated EPID house-made phantom. Method Materials: Leksell frame couch-mounted 3 unknown targets. Philipse largebore CT scanner ADAC Pinnacle planning computer delineate target isocenters determined. water initially by using laser then, applied apply table correction. Its movemenst monitored differences between...
Purpose: To investigate the feasibility of utilizing Dynamic Arc (DA) and IMRT with 5mm MLC leaf VERO treatment unit for SRS/FSRT brain cancer patients non‐invasive stereotactic treatments. The DA plans using (BrainLab Inc, USA) are compared cone‐based planning proton to evaluate their dosimetric advantages. Methods: Vero has unique features like no rotational or translational movements table during treatments, Arc/IMRT, tracking IR markers, limitation Ring rotation. Accuracies image fusions...
