Dramatic Response of a Large Sacral Chordoma to Intensity Modulated Proton Beam Therapy
Sacral chordomas are slow-growing, indolent, and locally invasive tumors that typically present with pain and neurologic dysfunction. Wide en-bloc surgical excision is the primary treatment, but achieving adequate margins is difficult and surgery is often associated with significant morbidity. Adjuvant radiation therapy (RT) is utilized to decrease the risk of local recurrence or as definitive ...
متن کاملCytodiagnosis of Sacral Chordoma.
We report the cytological findings of a sacro-coccygeal chordoma in a 53 year male diagnosed preoperatively by guided fine needle aspiration cytology. The smears shows characteristic Physalliphorous cells in a metachromatic background of myxoid material entrapping cords of cuboidal cells. Differential diagnosis in cytology include conventional and myxoid chondrosarcoma, myxoid liposarcoma, myxo...
متن کاملThe evaluation of lung doses for radiation pneumonia risk in stereotactic body radiotherapy: A comparison of intensity modulated radiotherapy, intensity modulated arc therapy, cyberknife and helical tomotherapy
Background: Radiation Pneumonia (RP) is one of the most extensive side effects in Stereotactic Body Radiotherapy (SBRT) of lung cancer. SBRT are performed by means of Intensity Modulated Radiotherapy (IMRT), Intensity Modulated Arc Therapy (IMAT), CyberKnife (CK) or Helical Tomotherapy (HT) treatment methods. In this study, we performed a plan study to determine the plan parameter such as the M...
متن کاملSurgical management of sacral chordoma.
Treatment results of 17 patients who were diagnosed with sacral chordoma between 1993 and 2007, were analyzed retrospectively. The mean duration of symptoms was 30.2 months. The mean tumour size was 10.7 cm; the location was S2 or more proximal in ten-patients. A wide resection was achieved in 14 patients, a marginal resection in one patient and two patients had intralesional excision. Seven pa...
متن کاملGrid: A location dependent intensity modulated radiotherapy for bulky tumors
Background: An effective method for management of large and bulky malignant tumors. This treatment modality is also known as Specially Fractionated Radiation Therapy (SFRT). In this treatment technique a grid block converted the open radiation field into a series of pencil beams. Dosimetric characteristics of an external beam grid radiation field have been investigated using experimental and Mo...
