Comparison of radiation dose to the left anterior descending artery by whole and partial breast irradiation in breast cancer patients.

Purpose: Breast conserving surgery (BCS) followed by whole breast irradiation (WBI) is the standard of care for breast cancer patients. However, there is a risk of coronary events with WBI therapy. In this study, we compared the radiation dose in the left anterior descending artery (LAD) in patients receiving partial breast irradiation (PBI) with WBI.

[Resection of a left obturator lymph node recurrence five years five months after surgery for rectal cancer].

A 62-year-old man with lower rectal cancer underwent abdominoperineal resection and dissection of the lateral pelvic lymph nodes. The cancer was staged at pT3pN0cM0, pStage II and did not show recurrence. Two years later, the patient had dysphagia and was diagnosed with esophageal cancer based on upper gastrointestinal endoscopy.

[Factors affecting adherence of breast cancer patients to adjuvant hormonal therapy and validation of the evaluation method].

Background: The long-term use of hormonal therapy is important for the treatment of patients with breast cancer. Therefore, we evaluated the methods used for measuring adherence and examined factors that influence compliance. Our goal was to improve overall adherence to the treatment.

The interspinous ligament should be removed for the decompression surgery with the case of lumbar spinal canal stenosis.

Introduction: Retrospective clinical study has done concerning the outcomes of lumbar spinal stenosis (LSS) patients treated with trans-interspinous ligament approach method. The object is to determine the efficacy of this procedure and to confirm that the interspinous ligament could be removed for the decompression surgery.

Method: Seventy patients were treated with this method and 63 patients were followed up for more than 4 years.

Dose selection for optimal treatment results and avoidance of complications.

What is the optimal treatment for metastatic brain tumors (MBTs)? We present our experience with gamma knife (GK) treatments for patients with five or more MBTs. Our new formula for predicting patient survival time (ST), which was derived by combining tumor control probability (TCP) calculated by Colombo's formula and normal tissue complication probability (NTCP) estimated by Flickinger's integrated logistic formula, was also evaluated. ST=a*[(C-NTCP)*TCP]+b; a, b, C: const.

Phrenic nerve conduction in the early stage of Guillain-Barre syndrome might predict the respiratory failure.

Objective: To investigate whether phrenic nerve conduction in the early phase of Guillain- Barre syndrome (GBS) predicts the need for respiratory assistance during the subsequent clinical course.

Material And Methods: We performed electrophysiological examinations of conventional peripheral nerve conduction and phrenic nerve conduction for GBS patients within 14 days from the onset. We excluded patients who had already been treated with immuno-related therapy and respiratory assistance.

Low-dose subcutaneous injection of botulinum toxin type A for facial synkinesis and hyperlacrimation.

Objective: To investigate the efficacy of low dose of botulinum toxin type A (BTX-A) for facial synkinesis and hyperlacrimation.

Material And Methods: Eleven patients suffering from facial synkinesis after Bell's palsy or facial nerve injury were treated with a low dose of BTX-A, 0.5-1.
