Purpose of the guidelines The primary objective these guidelines is to provide general clinicians with information that would guide them make informed choices available diagnosis/treatment strategies for esophageal cancer (intended malignant tumors epithelial origin, not any other non-epithelial esophagus or metastatic tumors). Furthermore, are also intended as an aid healthcare professionals than physicians, patients, and patients’ family members, obtain understanding fundamental...
Endoscopic resection (ER) includes endoscopic mucosal (EMR), wherein the affected lesion is held or aspirated and resected with a snare, submucosal dissection (ESD), which refers to en bloc of an extensive using IT knife hook [1][2][3][4].Other treatments available include photodynamic therapy (PDT), argon plasma coagulation (APC), electromagnetic therapy.
After publication of the guidelines, Committee on Guidelines for Diagnosis and Treatment Esophageal Cancer Japan Society has taken initiative to continue review contents guidelines conduct public relations dissemination/utilization activities.A revision is planned approximately 5 years after this guideline.In addition, a prompt report will be made when results clinical study(ies) are published or in accordance with changes medical circumstances, such as health insurance coverage.
PurposeTo evaluate the efficacy and safety of carbon-ion radiation therapy (RT) for mucosal melanoma head neck (MMHN) in Japan Carbon-Ion Radiation Oncology Study Group study.Methods MaterialsPatients with MMHN N0-1M0 status who were treated RT at 4 institutions between November 2003 December 2014 analyzed retrospectively. Two hundred sixty patients (male, 111; female, 149; median age, 68 years) histologically proven enrolled.ResultsPrimary sites included nasal cavity 178 patients, paranasal...
12 patients who had histological proven ganglioneuromas were investigated by computed tomography (CT) and magnetic resonance (MR) imaging. CT scans (n = 11), conventional spin-echo MR images 10) dynamic 5) acquired. All lesions showed a well defined, oval shape. Five (42%) calcification which was punctate in four coarse one on CT. attenuation predominantly low three of 10 (30%) intermediate the remaining seven (70%). In all signals mainly intensity T1 weighted (T1WI) high T2 (T2WI). Dynamic...
High linear energy transfer (LET) radiation carbon-ion radiotherapy (C-ion RT) is one of the most promising modalities for treating unresectable primary pancreatic cancers. However, how LET contributes to a therapeutic effect not clear. To assess whether there an enhanced high on tumour control, we aimed determine impact dose-averaged local control (LC) tumours.A retrospective analysis 18 patients with carcinomas treated definitive C-ion RT concurrent chemotherapy in 2013 was conducted. The...
To evaluate the safety and efficacy of carbon-ion radiation therapy (C-ion RT) for locally advanced sinonasal malignant tumors in a multicenter retrospective study (J-CROS 1402 HN).Clinical data were collected patients who had stage N0-1M0 received C-ion RT at 4 institutions Japan between November 2003 December 2014. Of 458 patients, 393 naïve 65 recurrent tumors. The located nasal cavity (n = 263), maxillary sinus 109), ethmoid 71), other locations 15). histologic types mucosal melanoma...
The purpose of this study was to evaluate the feasibility a new shortened 3-week treatment schedule carbon ion radiotherapy (CIRT) for prostate cancer. Beginning in May 2010, patients with T1b–T3bN0M0, histologically proven adenocarcinoma were enrolled phase II trial CIRT. Patients received 51.6 GyE 12 fractions over 3 weeks (protocol 1002). primary end point defined as incidence late adverse events that evaluated based on Common Terminology Criteria Adverse Events version 4.0. Biochemical...
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;...
We investigated the prevalences and risk factors for peri-implant diseases in Japanese adult dental patients attending a follow-up visit at hospitals or clinics as part of their maintenance program. This cross-sectional multicenter study enrolled with implants who attended regular check-ups periodontal program during period from October 2012 through September 2013. Patients least 3 years loading time were included study. The condition tissue was examined classified into following categories:...
Aim: To evaluate the efficacy of stereotactic body radiotherapy (SBRT) for pulmonary metastasis from colorectal cancer. Patients and Methods: Data 104 lesions 93 patients who underwent SBRT oligometastases cancer at ten Institutions were retrospectively analyzed. Toxicity was graded according to Common Terminology Criteria Adverse Events v4.0. Results: The median calculated biological effective dose using linear-quadratic model with α/β 10 Gy (BED10) 105.6 Gy. Adjuvant chemotherapy after...
A retrospective multicenter study was carried out to assess the clinical outcomes of carbon‐ion radiotherapy for head and neck malignancies (Japan Carbon‐Ion Radiation Oncology Study Group [J‐ CROS ] study: 1402 HN ). We evaluated safety efficacy in patients with major salivary gland carcinoma. Sixty‐nine treated at four Japanese institutions were analyzed. Thirty‐three (48%) had adenoid cystic carcinomas, 10 (14%) mucoepidermoid 26 (38%) other disease types. Three (4%) T1 disease, 8 (12%)...
Abstract There are no clinical reports of long‐term follow‐up after carbon‐ion radiotherapy (CIRT) using a dose 51.6 Gy (relative biological effectiveness [RBE]) in 12 fractions for localized prostate cancer, or comparison outcomes between passive and scanning beam irradiation. A total 256 patients with cancer who received CIRT at (RBE) two different delivery techniques (passive [ n = 45] 211]), were followed more than 1 year, analyzed. The biochemical relapse‐free (bRF) rate was defined by...
Intraoperative radiation therapy (IORT) is one of the methods used to deliver a large single dose tumor tissue while reducing exposure normal surrounding tissue. However, usefulness intraoperative electron for malignant gliomas has not been established. During period from 1987 1997, 32 patients with were treated IORT. The histological diagnoses anaplastic astrocytoma in 11 and glioblastoma 21 patients. Therapy consisted surgical resection using 12–15 Gy (median, 15 Gy). later underwent...
