BACKGROUND: For prostate cancer treatment, treatment options with minimal side effects are desired. External beam radiation therapy (EBRT) is non-invasive, standard of care and delivered in either conventional fractionation over 8 weeks or with moderate hypo-fractionation over about 5 weeks. Recent advances in radiotherapy technology have made extreme hypo-fractionated stereotactic body radiation therapy (SBRT) of prostate cancer feasible, which has not yet been introduced as a standard treatment method in Germany...

Radiation necrosis (RN) is a potential late complication of radiotherapy for intracranial malignancy, which is often associated with significant neurological morbidity. Prolonged treatment with high-dose corticosteroids or surgical resection has been the standard care for RN, but protracted steroid use can lead to significant side effects and surgical resection is not always feasible. The antivascular endothelial growth factor monoclonal antibody bevacizumab induces clinical and radiographic improvements in RN, with overall good tolerance...

Melanoma is the third most common cause of brain metastases, after lung and breast cancer. The management of melanoma brain metastases can be broadly divided into symptom control and therapeutic strategies. Supportive treatments include corticosteroids to reduce peritumoral edema, antiepileptics for seizure control, and medications to preserve cognitive function. Until recently, therapeutic strategies consisted primarily of local treatments, including surgery, whole-brain radiation therapy (WBRT), and stereotactic radiosurgery (SRS)...

BACKGROUND: Treatment of patients with multiple brain metastases has shifted to stereotactic radiosurgery, withholding whole-brain (WB) radiation therapy. However, radiation toxicity to the brain is a concern when treating multiple brain lesions with single-fraction stereotactic radiosurgery. OBJECTIVE: The purpose of this study was to determine the changes in brain radiation doses when treating various numbers of targets and lesion volumes. METHODS: We simulated different treatment plans with different combinations of varying tumor volumes including 0...

Renal Cell Carcinoma (RCC) has historically been considered a radioresistant cancer, and radiotherapy was usually delivered with a palliative goal. Stereotactic ablative radiotherapy (SABR) allows the delivery of high doses on small treatment volumes in a safe and effective way, thus opening the doors to new applicationsof radiotherapy both in the treatment of the primary and oligometastasic disease. Aim of the current review is to explore the state of art of SABR in the therapeutic approach to RCC.

We evaluated the accuracy of an in-house program in lung stereotactic body radiation therapy (SBRT) cancer patients, and explored the prognostic factors associated with the accuracy of deformable image registrations (DIRs). The accuracy of the 3 programs which implement the free-form deformation and the B-spline algorithm was compared regarding the structures on 4-dimensional computed tomography (4DCT) image datasets between the peak-inhale and peak-exhale phases. The dice similarity coefficient (DSC) and normalized DSC (NDSC) were measured for the gross tumor volumes from 19 lung SBRT patients...

Malignant epidural spinal cord compression (MESCC) is an oncologic emergency with the potential for devastating consequences for patients if not promptly diagnosed and treated. MESCC is diagnosed by imaging. MRI is by far the most sensitive test, preferably with gadolinium. Once the diagnosis of MESCC is suspected, patients with neurologic deficits should receive prompt administration of dexamethasone with a 10-mg IV loading dose followed by 4 mg every 6 h. Quick taper is recommended once the definitive treatment is established...
