PURPOSE The thyroid is not routinely considered an organ at risk in supraclavicular (SC) nodal radiation therapy (RT) for breast cancer. We compared the dosimetric impact of the following 2 RT planning techniques on the thyroid: (1) conventional single anterior field to encompass the SC nodal volume defined clinically; and (2) 3-dimensional conformal(More)
INTRODUCTION Stereotactic ablative body radiotherapy (SABR) is an emerging treatment technique for pulmonary metastases in which conventional Response Evaluation Criteria in Solid Tumours (RECIST) may be inadequate.

198 Background: The thyroid is not routinely considered an organ at risk in supraclavicular (SC) nodal radiotherapy (RT) for breast cancer. We aim to compare the dosimetric impact of two RT planning techniques on the thyroid: (1) conventional single anterior field to encompass the SC nodal volume defined using clinical and radiological landmarks; and (2)(More)

We present a case of a C2 nerve root haemangioblastoma in a 64-year-old man where the preoperative diagnosis was a spinal meningioma. An unexpectedly vascular tumour was found at initial(More)
