Health Utility of Pain Response Versus Nonresponse to Palliative Radiation Therapy for Symptomatic Bone Metastases: Analyses Based on Real-World Data from 26 Centers.

Utility values of responders and nonresponders are essential inputs in cost-effectiveness studies of radiation therapy for painful bone metastases but, to our knowledge, they have not been reported separately. We sought to determine the utility values of responders and nonresponders using data from a prospective observational study on bone metastases. The original prospective observational study was conducted at 26 centers in Japan.

Usefulness of arterial spin labeling MR angiography as preprocedural mapping for the intra-arterial chemotherapy in patients with maxillary sinus cancer: A case report.

Arterial spin labeling (ASL) magnetic resonance angiography (MRA) (ASL-MRA) is a newly developed method that can visualize small arteries, particularly those running tortuously and inferiorly at slow flow rates. It provides excellent visualization of the external carotid artery system, with superior performance in visualizing the middle meningeal artery (MMA) compared to that of computed tomography angiography (CTA). Here, we report a case of maxillary sinus carcinoma in which ASL-MRA revealed an ipsilateral ophthalmic artery originating from the MMA that was not visualized on CTA.

Quality of palliative radiotherapy assessed using quality indicators: a multicenter survey†.

We sought to identify potential evidence-practice gaps in palliative radiotherapy using quality indicators (QIs), previously developed using a modified Delphi method. Seven QIs were used to assess the quality of radiotherapy for bone metastases (BoM) and brain metastases (BrM). Compliance rate was calculated as the percentage of patients for whom recommended medical care was conducted.

[A Questionnaire Survey of Nurses on Pharmacist Services in the Emergency Rooms at Tokushukai Medical Group].

We conducted a multicenter survey of emergency room nurses to obtain information that would be useful for the establishment of pharmacist services in emergency rooms. Notably, 199 valid responses were obtained from 12 hospitals. The most common expectation from pharmacists in the emergency room was "drug management" (70.

The effect of arterial spin labeling MR angiography (ASL-MRA) in visualizing the branches of external carotid artery.

This study aimed to assess the performance of arterial-spin labeling MRA (ASL-MRA) for visualizing the external carotid artery (ECA) branches in comparison with time-of-flight MRA (TOF-MRA) and CT angiography (CTA). We retrospectively selected 31 consecutive patients, who underwent both MRAs and CTA, prior to the intra-arterial chemoradiotherapy (IACRT) for head and neck cancer. Four patients underwent IACRT bilaterally, so we analyzed 35 ECAs.

Factors associated with quality of life in patients receiving palliative radiotherapy for bone metastases: a secondary cross-sectional analysis of data from a prospective multicenter observational study.

Objective: To identify factors significantly associated with quality of life (QOL) and determine if these associations are strong enough to predict certain aspects of QOL without measuring them.

Methods: We conducted an exploratory secondary analysis of baseline data of 224 patients (enrolled between December 2020 and March 2021) from a previously published prospective observational study on radiotherapy for bone metastases at 26 centres. Using univariable linear regression, we assessed the association between patient/treatment factors and QOL scale scores as measured by the European Organization for Research and Treatment of Cancer (EORTC) QOL Questionnaire Core 15-Palliative (QLQ-C15-PAL) and the EORTC QOL Questionnaire Bone Metastases module (QLQ-BM22).

Who should receive single-fraction palliative radiotherapy for gastric cancer bleeding?: An exploratory analysis of a multicenter prospective observational study (JROSG 17-3).

Purpose: Although the Palliative Prognostic Index (PPI) has been used to predict survival in various cancers, to our knowledge, no study has examined its applicability in gastric cancer. This study aimed to determine the baseline PPI cutoff value for recommending single-fraction radiotherapy in patients with bleeding gastric cancer.

Materials And Methods: This was a secondary analysis of the Japanese Radiation Oncology Study Group (JROSG) 17-3, a multicenter prospective study of palliative radiotherapy for bleeding gastric cancer.

Palliative Radiation Therapy without Chemotherapy for a Patient with Monomorphic Epitheliotropic Intestinal T Cell Lymphoma: A Case Report.

Monomorphic epitheliotropic intestinal T cell lymphoma (MEITL), which used to be known as type 2 enteropathy-associated T cell lymphoma, is a rare lymphoma and is generally treated with chemotherapy. However, the MEITL prognosis is poor, and intestinal lymphoma including MEITL has the risk of bowel perforation not only at presentation but also during chemotherapy. A 67-year-old man was diagnosed with MEITL after presenting in our emergency room with bowel perforation.

Comparison of intensity-modulated radiotherapy with the 5-field technique, helical tomotherapy and volumetric modulated arc therapy for localized prostate cancer.

The outcomes of three methods of intensity-modulated radiation therapy (IMRT) for localized prostate cancer were evaluated. Between 2010 and 2018, 308 D'Amico intermediate- or high-risk patients were treated with 2.2 Gy daily fractions to a total dose of 74.

Temporal Profiles of Symptom Scores After Palliative Radiotherapy for Bleeding Gastric Cancer With Adjustment for the Palliative Prognostic Index: An Exploratory Analysis of a Multicentre Prospective Observational Study (JROSG 17-3).

Aims: Although palliative radiotherapy for gastric cancer may improve some symptoms, it may also have a negative impact due to its toxicity. We investigated whether symptoms improved after radiotherapy with adjustment for the Palliative Prognostic Index (PPI) considering that patients with limited survival tend to experience deterioration of symptoms.

Materials And Methods: This study was an exploratory analysis of the Japanese Radiation Oncology Study Group study (JROSG 17-3).

Treatment response after palliative radiotherapy for bleeding gastric cancer: a multicenter prospective observational study (JROSG 17-3).

Background: Palliative radiotherapy seems to be rarely performed for incurable gastric cancer. In this first multicenter study, we examined the effectiveness of palliative radiotherapy and investigated whether biologically effective dose (BED) is associated with survival, response, or re-bleeding.

Methods: Eligibility criteria included blood transfusion or hemoglobin levels < 8.

Stereotactic body radiotherapy using a hydrogel spacer for localized prostate cancer: A dosimetric comparison between tomotherapy with the newly-developed tumor-tracking system and cyberknife.

Purpose: With a new tumor-tracking system (Synchrony®) for tomotherapy (Radixact®), the internal and set-up margins can be tightened, like cyberknife (CyberKnife®), in the planning of stereotactic body radiotherapy (SBRT) for prostate cancer. Recently, the usefulness of placing a hydrogel spacer between the prostate and rectum has been established in prostate radiotherapy. We evaluated the characteristics of tomotherapy plans with the tumor-tracking system and compared them with cyberknife SBRT plans for localized prostate cancer using a hydrogel spacer.

Successful Endovascular Repair of a Kommerell's Diverticulum and a Right-Sided Aortic Arch.

Background: A 57-year-old woman was diagnosed with Kommerell's diverticulum in the setting of a right aortic arch on computed tomography.

Case Report: Although asymptomatic, the maximum diameter of the aneurysm was 55 mm; thus, she underwent surgery to prevent rupture of the aneurysm. A bypass was constructed from the left common carotid artery to the left subclavian artery.

Stereotactic body radiotherapy using the forward-planned static-port tomotherapy for lung cancer: a novel planning technique with the newly-developed mode.

With the newly-developed static-port forward-planning (FP) mode of tomotherapy, the ratio of the dose of the planning target volume (PTV) periphery to the maximum dose can be easily adjusted by modifying leaf margins when planning stereotactic body radiotherapy (SBRT). The purpose of this study was to evaluate the characteristics of FP plans compared to helical intensity-modulated radiotherapy (IMRT) and helical 3D conformal radiotherapy (3DCRT) plans of SBRT for lung tumors. The three plans were created for 14 tumors in 11 patients.

Long-term results of intensity-modulated radiotherapy with three dose-fractionation regimens for localized prostate cancer.

We evaluated long-term outcomes of three protocols of intensity-modulated radiation therapy (IMRT) for localized prostate cancer. Between 2005 and 2014, 348 patients were treated with 5-field IMRT. The first 74 patients were treated with a daily fraction of 2.

Radiation-induced dermatitis after administration of mogamulizumab for adult T-cell leukaemia/lymphoma: a multi-institutional retrospective study.

Background: Cutaneous adverse reactions are frequently induced by mogamulizumab. Cases of Stevens-Johnson syndrome, toxic epidermal necrolysis and severe photosensitivity related to mogamulizumab have been reported. This study investigated whether severe radiation-induced dermatitis occurred in patients undergoing radiotherapy after the administration of mogamulizumab for adult T-cell leukaemia/lymphoma.

Very Distal Radius Wedge Osteotomy for Kienböck's Disease: Case Series.

Background: Radius osteotomy is one of the standard surgical procedures for the treatment of Kienböck's disease. Unfortunately, radius osteotomy can result in an incongruous distal radio-ulnar joint (DRUj) postoperatively, because the procedure is performed proximal to the DRUj.

Methods: A very distal radius wedge osteotomy was performed as a 15-degree lateral closing wedge osteotomy with the apex of the wedge distal to that of conventional lateral closing wedge osteotomy; this procedure was developed to avoid postoperative incongruous DRUj.

Influence of Naftopidil on Plasma Monoamine Levels and Lower Urinary Tract Symptoms Associated with Benign Prostatic Hyperplasia.

Objectives: To clarify the influence of naftopidil, an α1D/A -adrenergic receptor antagonist, on the autonomic nervous system, we examined the relation between lower urinary tract symptoms (LUTS) and the plasma monoamine levels before and after naftopidil treatment in benign prostatic hyperplasia (BPH) patients.

Methods: A total of 43 patients with BPH were studied. The frequency of urination, international prostate symptom score (IPSS), quality of life (QOL) index, overactive bladder symptom score (OABSS), and plasma monoamine levels (adrenaline, noradrenaline, dopamine, and serotonin) were evaluated before and after naftopidil treatment.
