: We investigated the usefulness of diffusion-weighted imaging (DWI) for detecting changes in the structure of hypoxic cells by evaluating the correlation between 18F-fluoroazomycin arabinoside (FAZA) positron emission tomography activity and DWI parameters in head and neck carcinoma. The diffusion coefficient corresponding to the slow compartment of a two-compartment model had a significant positive correlation with FAZA activity (ρ = 0.58, P = 0.016), whereas the diffusional kurtosis from diff...

PURPOSE: The Working Group of the Gynecological Tumor Committee of the Japanese Radiation Oncology Study Group (JROSG) published recommendations for contouring high-risk clinical target volumes (HR-CTV) on CT for 3-dimentional image-guided brachytherapy for cervical cancer. The purpose of this study was to compare HR-CTV delineated on CT, referencing recommendations from JROSG, with HR-CTV delineated on MRI, referencing consensus guidelines from the Groupe Europeen de Curietherapie-European Soci...

BACKGROUND/AIM: To investigate outcomes of patients with cervical cancer who received radiation therapy for extrapelvic lymph node recurrence after initial pelvic radiotherapy. PATIENTS AND METHODS: The treatment charts of 20 patients were retrospectively reviewed, and factors influencing patient's prognosis were statistically analyzed. RESULTS: The three-year in-field tumor control rate was 55% and overall survival (OS) at 2, 3, and 5 years was 55%, 45%, and 37.5%, respectively. The rate of the...

Objective The prognostic value of positron emission tomography/computed tomography (PET/CT) with 18F-fluoroazomycin arabinoside (FAZA) was evaluated in patients with head and neck squamous cell carcinoma (HNSCC) who underwent chemoradiotherapy (CRT).

In Japan, cetuximab with concurrent bioradiotherapy (BRT) for squamous cell carcinoma of head and neck (SCCHN) was approved in December 2012. We herein report our initial experience of BRT, with special emphasis on acute toxicities of this combination therapy. Thirty-one non-metastatic SCCHN patients who underwent BRT using cetuximab between July 2013 and June 2014 were retrospectively evaluated. All patients received cetuximab with a loading dose of 400 mg/m2 one week before the start of radiot...

The purpose of this study was to retrospectively evaluate the incidence of delayed renal dysfunction after total body irradiation (TBI) in long-term survivors of TBI/hematopoietic stem cell transplantation (HSCT). Between 1989 and 2006, 24 pediatric patients underwent TBI as part of the conditioning regimen for HSCT at Chiba University Hospital. Nine patients who survived for more than 5 years were enrolled in this study. No patient had any evidence of renal dysfunction prior to the transplant a...

Background Among patients with T4 thoracic esophageal squamous cell carcinoma (TESCC), it is unclear whether the outcomes of late responders who undergo high-dose chemoradiotherapy (CRT) followed by salvage esophagectomy differs from those of early responders who undergo low-dose CRT followed by esophagectomy.
