It has been suggested that pain control during intracavitary brachytherapy for cervical cancer is insufficient in most hospitals in Japan. Our hospital began using caudal epidural anesthesia during high-dose-rate (HDR) intracavitary brachytherapy in 2011. The purpose of the present study was to retrospectively investigate the effects of caudal epidural anesthesia during HDR intracavitary brachytherapy for cervical cancer patients.

Methods: Sixty-seven patients with Stage I and II mobile tongue cancer were treated with high-dose-rate interstitial radiation therapy, with or without external beam radiation therapy, between 1997 and 2007. The median dose of interstitial radiation therapy was 50 Gy in 10 fractions over 6 days.
Aim: To clarify the clinical significance of definitive chemoradiotherapy (CRT) and CRT followed by esophagectomy for cT4 esophageal cancer.
Patients And Methods: The treatment results for cT4 esophageal cancer were examined in 81 patients who received definitive CRT [radiation 50-70 Gy, cisplatin and 5-fluorouracil; group I] and 19 patients who underwent esophagectomy after preoperative CRT [40Gy, Group II].
Results: Among the 81 patients in group I, toxicities (grade 3 or 4) were observed in 32 patients, while partial response and complete response were recognized in 8 and 47 patients, respectively.
Purpose: The aim of this study was to evaluate the efficacy and side effects of radioimmunotherapies with Zevalin(®) (RIT-Z) in Japanese patients with low-grade B-cell non-Hodgkin lymphoma (NHL).
Materials And Methods: Sixty-two patients with NHL were enrolled. Based on histology, 49 of the patients had follicular lymphoma and 23 had other lesions.
Laryngeal radionecrosis is one of the most troublesome late complications of radiotherapy, because it is frequently resistant to treatment and laryngectomy is required in the worst case. Here, we report a case of laryngeal radionecrosis, successfully treated by use of hyperbaric oxygen (HBO) therapy, in which laryngectomy was avoided. A 67-year-old male received radical chemoradiotherapy (CRT) for mesopharyngeal cancer, which included radiotherapy with a total dose of 71.

In this study, the histopathological effects and toxicities following concurrent chemoradiotherapy were examined. The subjects consisted of 15 patients (10 men and 5 women) who were treated with S-1 (60-80 mg/day, 4 weeks), superselective intra-arterial infusion of CBDCA (300 mg/body) and radiation therapy (total dose 30-36 Gy) in our department from 2005 to 2009.

They most commonly occur in the kidney, but on rare occasions they occur in extrarenal sites. We present a case of angiomyolipomas in the mediastinum and lung, possibly associated with lymphangioleiomyomatosis and tuberous sclerosis complex.

Patients And Methods: From May 2004 through March 2010, 154 patients with local and locally advanced prostate cancer underwent EBRT + HDR-BT. One hundred thirteen patients with more than 6 months follow-up were evaluated.
Purpose: To evaluate the therapeutic outcomes and late toxicities in patients treated by high-dose-rate brachytherapy (HDR-BT) with external beam radiotherapy (EBRT) for localized or locally advanced prostate cancer.
Materials And Methods: From May 2004 to September 2008, 86 men were treated by HDR-BT with EBRT for localized or locally advanced prostate cancer at the National Hospital Organization Kyushu Medical center. The median EBRT and HDR-BT doses were 40 Gy and 30 Gy, respectively.

This report describes a rare case of metastatic hepatocellular carcinoma (HCC) presenting a huge mass in the left external auditory canal (EAC). The patient was a 55-year-old man with hepatitis B virus-related HCC. He presented to our department with a three-month history of increasing left otalgia, and hearing loss with recent fresh aural bleeding.

Seventeen patients were treated with radiotherapy alone, and 12 were treated with a combination of chemotherapy and radiotherapy.

A median dose of 5 mg of bleomycin was injected locally, and 16-20 Gy was delivered to the area surrounding applicators for control of the tumor implant during the initial two days. The two-year local recurrence-free survival rate was 96% [T1, 2: 100% (8/8, 15/15), T3: 80% (4/5)].
