BACKGROUND Patients with malignant melanoma may develop brain metastases during the course of the disease, requiring radiotherapeutic treatment. In patients with 1-3 brain metastases, radiosurgery has been established as a treatment option besides surgery. For patients with 4 or more brain metastases, whole brain radiotherapy is considered the standard treatment. In certain patients with brain ...
Postoperative hemithoracic irradiation is regarded as an important part of the curative treatment for resectable malignant pleural mesothelioma (MPM). Because the clinical target volume in postoperative MPM is irregular and surrounded by dose-limiting critical structures, intensity-modulated radiation therapy (IMRT) is thought to be suitable. However, postoperative hemithoracic IMRT remains exp...
BACKGROUND AND PURPOSE To present a novel helical TomoTherapy-based method for whole breast radiotherapy that has better dosimetry and also has acceptable low-dose regions for lungs, heart, and contralateral breast compared with tangential field-in-field IMRT (FIF-IMRT). MATERIAL AND METHODS Ten patients with left-side breast cancer were planned with low-dose-area-constrained helical TomoTher...
PURPOSE To evaluate the feasibility of pre-operative radiotherapy (54 Gy) with Helical Tomotherapy (HT) followed by surgery. METHODS AND MATERIALS Ten patients with non-metastatic resectable retroperitoneal liposarcomas were treated by pre-operative tomotherapy (54 Gy) and surgery. Clinical and biological toxicities were evaluated on the CTCAEV3.0 scale. For nine patients, delivered tomothera...
