BACKGROUND: Vaginal brachytherapy, a common treatment of endometrial cancer, is associated with high rates of vaginal stenosis. Recommendations for vaginal dilator use to minimize stenosis generally include 3 times per week for approximately 10 minutes per use. However, adherence rates range widely and are generally well less than 50%. OBJECTIVES: The aims of this study were to assess feasibility of recruitment to a study of dilator use and test a theoretically driven enhanced educational program (EEP) to increase adherence...

Presented is the case of an epiglottal fibrosarcoma in a dog. The location of the mass resulted in challenges in the delivery of adequate dose to the tumor, and herein we describe the treatment using an electronic brachytherapy source. The treatment consisted of four Gy fractions, twice daily for a total of 10 fractions (40 Gy total). Visual reevaluation two weeks after treatment supported adequate spatial dose delivery, and the patient was reportedly improved six weeks after treatment. We demonstrate that plesiotherapy using an electronic brachytherapy device is feasible and may be useful in the treatment of carefully selected veterinary tumors...

Malignant melanoma (MM) arising primarily in the cervix is exceedingly rare and has a poor prognosis. We report the case of a primary MM of the cervix in a 64-year-old woman with vaginal bleeding. She presented with a cervical amelanotic lesion which on biopsy rendered the diagnosis of MM. The patient was staged as International Federation of Gynecology and Obstetrics IIB and underwent Wertheim-Meigshysterectomy followed by brachytherapy. One year later, she was diagnosed with a large pelvic relapse for which surgery was performed...

INTRODUCTION: Radiotherapy is essential for achieving and maintaining local control in head and neck rhabdomyosarcoma (HNRMS) patients. However, radiotherapy may cause outgrowth disturbances of facial bone and soft tissue, resulting in facial asymmetry. The aim of this study was to develop a method to visualize and measure facial asymmetry in HNRMS survivors using three-dimensional (3D) imaging techniques. METHODS: Facial deformity was evaluated in a multidisciplinary clinical assessment of 75 HNRMS survivors, treated with external beam radiotherapy (EBRT, n = 26) or Ablative surgery, MOulage brachytherapy, and REconstruction (AMORE, n = 49)...

Brachytherapy is a type of radiotherapy wherein titanium capsules containing therapeutic radioisotopes are implanted within tumor tissues, enabling high-dose radio-irradiation to tumor tissues around the seeds. Although marked therapeutic effects have been demonstrated, brachytherapy needs complicated implantation technique under general anesthesia and the seeds could migrate to other organs. The aim of this study is to establish a novel brachytherapy using biocompatible, injectable thermo-responsive polymers (polyoxazoline; POZ) labeled with yttrium-90 ((90)Y), which can self-aggregate above a specific transition temperature, resulting in long-term intratumoral retention of radioactivity and therapeutic effect...

BACKGROUND: Recent studies have shown a decrease in the overall use of radiation therapy in the treatment of prostate cancer over the past several decades, as well as a more conservative overall treatment approach. We aim to determine whether this trend continued from 2004 to 2013, and to determine whether there were changes in utilization for various types of radiation. METHODS: We conducted this retrospective study using the National Cancer Database. We identified 706 877 patients with sufficient treatment information diagnosed with stage IIA prostate cancer between 2004 and 2013...

Magnetic resonance imaging (MRI) is increasingly being used in radiation therapy, and integration of MRI into brachytherapy in particular is becoming more common. We present here a systematic review of the basic physics and technical aspects of incorporating MRI into prostate brachytherapy. Terminology and MRI system components are reviewed along with typical work flows in prostate high-dose-rate and low-dose-rate brachytherapy. In general, the brachytherapy workflow consists of five key components: diagnosis, implantation, treatment planning (scan + plan), implant verification, and delivery...
