Single-Fraction Palliative High-Dose-Rate Brachytherapy for Symptom Management in a 97-Year-Old Patient With Dementia.

Delivering cancer treatment to elderly patients with dementia is often challenging. We describe performing palliative surface mold brachytherapy (SMBT) in an elderly patient with advanced dementia for pain control using music therapy to assist with agitation. The patient was a 97-year-old Japanese woman with advanced dementia.

Prediction of out-of-field recurrence after chemoradiotherapy for cervical cancer using a combination model of clinical parameters and magnetic resonance imaging radiomics: a multi-institutional study of the Japanese Radiation Oncology Study Group.

We retrospectively assessed whether magnetic resonance imaging (MRI) radiomics combined with clinical parameters can improve the predictability of out-of-field recurrence (OFR) of cervical cancer after chemoradiotherapy. The data set was collected from 204 patients with stage IIB (FIGO: International Federation of Gynecology and Obstetrics 2008) cervical cancer who underwent chemoradiotherapy at 14 Japanese institutes. Of these, 180 patients were finally included for analysis.

Clinical value of serum biomarkers, squamous cell carcinoma antigen and apolipoprotein C-II in follow-up of patients with locally advanced cervical squamous cell carcinoma treated with radiation: A multicenter prospective cohort study.

There are currently no reliable, established serum biomarkers to predict the prognosis of radiotherapy for advanced cervical cancer. We aimed to identify serum biomarkers for survival after radiotherapy for cervical cancer. In this multicenter prospective cohort study, the usefulness of pre- and posttreatment serum protein levels of potential biomarkers, including squamous cell carcinoma antigen (SCC-Ag), apolipoprotein C-II (ApoC-II), matrix metalloproteinase (MMP)1, and MMP2, were evaluated together with clinical factors in 145 cervical cancer patients in order to determine their suitability to predict survival.

A multi-institutional survey of the quality of life after treatment for uterine cervical cancer: a comparison between radical radiotherapy and surgery in Japan.

This study aimed to research the post-treatment quality of life (QOL) between radiotherapy (RT)- and operation (OP)-treated early cervical cancer survivors, using separate questionnaires for physicians and patients. We administered an observational questionnaire to patients aged 20-70 years old with Stages IB1-IIB cervical cancer who had undergone RT or OP and without recurrence as outpatients for ≥6 months after treatment. We divided 100 registered patients equally into two treatment groups (n = 50 each).

Acute necrotizing pancreatitis as a fatal complication following DC Bead transcatheter arterial chemoembolization for hepatocellular carcinoma: A case report and review of the literature.

Transcatheter arterial chemoembolization (TACE) is one of the most effective palliative measures for patients with inoperable hepatocellular carcinoma (HCC). Acute pancreatitis is a rare but well-known complication following TACE. We herein present the case of a patient with HCC who developed fatal complications (acute necrotizing pancreatitis and upper gastrointestinal ulcers) after TACE with DC Beads.

[Feasibility and Safety of Dexmedetomidine Sedation in Transarterial Embolization for Hepatocellular Carcinoma with Hepatitis C-Related Cirrhosis].

Background: Dexmedetomidine (Precedex®)is an agonist of a2-adrenergic receptors in certain parts of the brain. It was approved for "procedural sedation in the non-intubation in under local anesthesia" in June 2013 in Japan. However, because of metabolism delay, dexmedetomidine has to be administered carefully to patients with liver dysfunction.

Hyperthermia classic commentary: 'A randomized clinical trial of radiation therapy versus thermoradiotherapy in stage IIIB cervical carcinoma' by Yoko Harima, International Journal of Hyperthermia 2001;17:97-105.

In our classic paper, we investigated both the clinical response and survival of patients treated with radiotherapy (RT) or thermoradiotherapy (TRT; RT plus hyperthermia [HT]) for Stage IIIB cervical carcinomas. Our study clearly demonstrated that TRT can result in beneficial effects for complete response and/or local relapse-free survival. To date, six randomized trials including our study have been published on the additive effect of HT in patients with locally advanced cervical cancer.

Results of concomitant chemoradiation for cervical cancer using high dose rate intracavitary brachytherapy: study of JROSG (Japan Radiation Oncology Study Group).

The purpose of this study was to clarify outcome for concurrent chemoradiation (CT-RT) in locally advanced cervix cancer in Japan. This is a non-randomized retrospective analysis of 226 patients treated with definitive CT-RT or radiotherapy alone (RT alone) in nine institutions between 2001 and 2003. External irradiation consisted of whole pelvic irradiation and pelvic side wall boost irradiation, using a central shield during the latter half of the treatment with the anteroposterior parallel opposing technique.

Expression of Ku80 in cervical cancer correlates with response to radiotherapy and survival.

To reveal the genes relevant for prediction of cervical cancer after radiotherapy, we previously carried out cDNA microarray experiments on primary cervical cancer comparing patients with a complete response (CR) and those with no change (NC). Some of these genes had already been associated with the radiation response, such as x-ray repair cross-complementing 5 (XRCC5), which was found more in radioresistant tumors than in radiosensitive ones. The aim of this study was to confirm the possible roles of XRCC5 mRNA levels by a real-time polymerase chain reaction method in 20 cervical cancers, and Ku80 protein, which is the gene product of XRCC5, using a histopathologic method of formalin-fixed sections of tumor biopsies in determining tumor response to radiotherapy and survival in 89 patients with cervical cancer.

A case of metastatic bone tumor of missed lung cancer showing unusual manifestations on chest radiogram.

We encountered a patient who had a primary unknown carcinoma with lumbago caused by lumbar vertebral metastasis as the initial chief complaint. Autopsy revealed primary pulmonary adenocarcinoma. Abnormal findings noted on plain chest radiogram and chest CT led to misdiagnosis as inflammatory changes.

Classification of sensitivity or resistance of cervical cancers to ionizing radiation according to expression profiles of 62 genes selected by cDNA microarray analysis.

To identify a set of genes related to radiosensitivity of cervical squamous cell carcinomas and to establish a predictive method, we compared expression profiles of 9 radiosensitive and 10 radioresistant tumors obtained by biopsy before treatment, on a cDNA microarray consisting of 23,040 human genes. We identified 121 genes whose expression was significantly greater in radiosensitive cells than in radioresistant cells, and 50 genes that showed higher levels of expression in radioresistant cells than in radiosensitive cells. Some of these genes had already known to be associated with the radiation response, such as aldehyde dehydrogenase 1 (ALDH1) and X-ray repair cross-complementing 5 (XRCC5) (P<.
