Vulvar cancer is a rare gynecological malignancy with incidence rates steadily increasing over the past 10 years. Despite aggressive treatment, recurrent disease is common. Vulvar cancer recurrence poses a significant therapeutic challenge as most patients have been previously treated with surgery and/or radiation limiting the options for additional treatment. There are no consensus guidelines ...
Our purpose was to develop recommendations for contouring the computed tomography (CT)-based high-risk clinical target volume (CTVHR) for 3D image-guided brachytherapy (3D-IGBT) for cervical cancer. A 15-member Japanese Radiation Oncology Study Group (JROSG) committee with expertise in gynecological radiation oncology initiated guideline development for CT-based CTVHR (based on a comprehensive ...
PURPOSE This report compares the Nucletron NPS and PLATO planning system for patients treated for cervix cancer. MATERIALS AND METHODS This study compares calculations generated using the older NPS (version 11.43) planning system and the more recent PLATO (version 14.1) system for two cases: 1) a single dwell position and 2) an actual patient application using a tandem and ovoid. RESULTS Fo...
The technology for construction and application of flexible dosimetric assemblies with LiF:Mg,Ti microcrystals (sizes about 0.1 mm) off-line measurements the spatial distribution absorbed dose inside organs at risk (rectum, urethra, vagina) high rate brachytherapy in oncoginecology has been developed. transfer from usage luminescent dosimeters macro sizes (more than 1 to microdosimetrs mm, comb...
Conservative management of a perianal rhabdomyosarcoma in a 2-year old child by Papillon’s technique
Rhabdomyosarcoma (RMS) is the most common sarcoma in paediatric patients. A perianal site is unusual and is associated with a low cure rate. The few cases of reported perianal RMS have been associated with sequelae. Here, we report the case of a 29-month-old male child who received sequential treatment by surgery, chemotherapy and radiotherapy inspired by Papillon's irradiation of adult anal/lo...
Treatment of gynecological cancer commonly involves pelvic radiation therapy (RT) and/or brachytherapy. A commonly observed side effect of such treatment is radiation-induced vaginal stenosis (VS). This review analyzed the incidence, pathogenesis, clinical manifestation(s) and assessment and grading of radiation-induced VS. In addition, risk factors, prevention and treatment options and follow-...
