Abstract Herein, we investigate the long-term clinical outcomes for cervical cancer patients treated with in-room computed tomography–based brachytherapy. Eighty Stage IB1–IVA cancer, who had undergone treatment combined 3D high-dose rate brachytherapy and conformal radiotherapy between October 2008 May 2011, were retrospectively analyzed. External beam (50 Gy) central shielding after 20–40 Gy was performed each patient. Cisplatin-based chemotherapy administered concurrently to...
The purpose of this study was to compare carbon ion radiotherapy (C-ion RT) and stereotactic (SBRT) with photon beams for the treatment hepatocellular carcinoma (HCC), specifically regard dose volume parameters target coverage normal tissue sparing. Data 10 patients who were treated using C-ion RT a total 60 Gy(RBE) in four fractions used. virtual plan SBRT simulated on planning computed tomography images RT. Dose such as minimum covering 90 % (PTV D90), homogeneity index (HI), conformity...
Abstract Background & Aims Carbon‐ion radiation therapy has shown encouraging results in hepatocellular carcinoma patients single‐centre studies. We evaluated the effectiveness and safety of short‐course carbon‐ion for a multicentre study conducted by Japan Carbon Ion Radiation Oncology Study Group. Methods Consecutive who were treated with four or fewer fractions at Japanese institutions between April 2005 November 2014 analysed retrospectively. The primary outcome was overall survival;...
In each relay station in an SFN (single frequency network) for DTB (digital terrestrial broadcasting), the loop interference is caused by coupling from transmitting antenna to receiving antenna. The must be reduced allowable level order avoid problems with distortion and oscillation. We propose a frequency-domain adaptive cancellation algorithm using reference signals carried OFDM signal. principle of proposed outlined usefulness verified results computer simulations.
We report a new technique of brachytherapy consisting intracavitary combined with computed tomography (CT)-guided interstitial for locally advanced cervical cancer. A Fletcher-Suit applicator and trocar point needles were used performing high-dose rate under in-room CT guidance. First, tandem ovoids implanted into the patient's vagina uterus by conventional method. Based on clinical examination MRI/CT imaging, operating radiation oncologists decided positions insertion in tumor depth from...
Radiation therapy (RT) for metastatic pelvic lymph nodes (PLNs) is not well established in cervical cancer. In this study the correlation between size of and control doses RT was analyzed. Between January 2002 December 2007, 245 patients with squamous cell carcinoma cervix treated a combination external beam irradiation or without boost high-dose rate brachytherapy were investigated. Size node measured by computed tomography before just after 50 Gy RT. Of patients, 78 had PLN metastases,...
To evaluate the safety and efficacy of carbon ion radiotherapy (C-ion RT) for 80 years or older patients with hepatocellular carcinoma (HCC). Eligibility criteria this retrospective study were: 1) HCC confirmed by histology typical hallmarks imaging techniques four-phase multidetector-row computed tomography dynamic contrast-enhanced magnetic resonance imaging; 2) no intrahepatic metastasis distant metastasis; 3) findings suggesting direct infiltration gastrointestinal tract; 4) performance...
To assess the efficacy of uterine artery embolization (UAE) for management primary postpartum hemorrhage (PPH) and to determine factors associated with clinical outcomes especially in relation ovarian artery.A retrospective analysis 33 patients who underwent UAE PPH was performed. Clinical data were used regarding maternal characteristics, cause bleeding, mode delivery, bleeding onset after risk PPH, presence coagulopathy, details procedure, types flow. We defined two flow by initial...
IntroductionA prospective multicenter registry study was started in May 2016 Japan to evaluate the efficacy and safety of proton beam therapy (PBT) for hepatocellular carcinoma (HCC).MethodsPatients who received PBT HCC from June 2018 were registered database Particle Beam Therapy Committee Subcommittee Japanese Society Radiation Oncology (JASTRO). Overall survival (OS), progression-free (PFS) local recurrence evaluated.ResultsOf 755 cases, 576 with initial no duplicate cancer evaluated. At...
We compared clinical outcomes of carbon ion radiotherapy and transarterial chemoembolization in the treatment hepatocellular carcinoma.Data 477 patients with carcinoma who had undergone or between April 2007 September 2016 were retrospectively reviewed. Treatment naïve single HCC, underwent as a primary included. Clinical treatments after utilizing propensity score matching.Of 124 received 353 chemoembolization, 31 23 met our inclusion criteria, respectively. After matching, 17 matched pairs...
Lung cancer is a leading cause of cancer-related deaths worldwide. Radiotherapy an essential treatment modality for inoperable non-small cell lung (NSCLC). Stereotactic body radiotherapy (SBRT) the standard early-stage NSCLC because its favorable local control (LC) compared to conventional radiotherapy. Carbon ion (CIRT) kind external beam characterized by steeper dose distribution and higher biological effectiveness. Several prospective studies have shown outcomes. However, there no direct...

Management of patients with bone sarcoma who are unsuitable for surgery is challenging. We aimed to analyze the clinical outcomes among such were treated carbon ion radiotherapy (C-ion RT). reviewed medical records C-ion RT between April 2011 and February 2019 analyzed data 53 patients. Toxicities classified using National Cancer Institute’s Common Terminology Criteria Adverse Events (Version 4.0). The median follow-up duration all was 36.9 months. Histologically, 32 had chordoma, 9...
Prospective evidence supporting the safety and efficacy of carbon-ion radiotherapy (C-ion RT) for hepatocellular carcinoma (HCC) remains lacking. This prospective study aimed to evaluate hypofractionated C-ion RT in patients with HCC.The inclusion criteria were as follows: (1) pathologically or clinically diagnosed HCC; (2) measurable tumor size ≤10 cm; (3) absence major vascular invasion; (4) no extrahepatic metastasis; (5) alimentary tract was not adjacent target lesion (>1 cm); (6)...
Background/Aim: The relationship between sarcopenia and prognosis in carbon ion radiotherapy (C-ion RT) for hepatocellular carcinoma (HCC) has not yet been reported, therefore we analyzed the presence or absence of before C-ion RT as a prognostic factor patients with HCC. Patients Methods: Data were retrospectively collected who had undergone HCC September 2010 December 2016. For defining sarcopenia, skeletal muscles third lumbar vertebrae level measured. Clinical outcomes compared...
