[Stereotactic radiosurgery of brain tumors].

Stereotactic radiosurgery is today a well-established treatment modality for various intracranial pathologies. The principle of high dose focused intracranial radiation guided by stereotactic technique ("Gamma Knife") was introduced by the Swedish neurosurgeon Prof. Lars Leksell in 1968.

Interval From Simulation Imaging to Treatment Delivery in SABR of Lung Lesions: How Long is Too Long for the Lung?

Purpose: The purpose of this study was to evaluate the effect of delay between planning computed tomography (CT) used as a basis for treatment planning and the start of treatment (delay planning treatment [DPT]), on local control (LC) for lung lesions treated by SABR.

Methods And Materials: We pooled 2 databases from 2 monocentric retrospective analysis previously published and added planning CT and positron emission tomography (PET)-CT dates. We analyzed LC outcomes based on DPT and reviewed all available cofounding factors among demographic data and treatment parameters.

The Role of Stereotactic Radiotherapy in the Management of Melanoma, A Retrospective Single Institute Preliminary Study of 30 Patients.

Cutaneous melanoma is the third most common type of skin cancer in the world. The incidence of melanoma is increasing in most countries, however, mortality seems to be slowly decreasing. The treatment of advanced cutaneous melanoma changed radically since 2011.

[Stereotactic radiotherapy with CyberKnife and linear accelerator in the management of malignant melanoma].

Stereotactic radiotherapy gains more and more importance in the management of malignant melanoma, owing to technical developments of recent years. This approach might be applied with success in solitary or oligometastatic cases, since the deliverable biological dose is far higher than that of conventional radiotherapy. Beyond chemotherapy of decreasing importance, there is a widening range of new targeted and immunotherapy agents, leading to longer survival times even in disseminated stages.

[Radiotherapy of pancreatic cancer].

The therapy of pancreatic cancer is fundamentally based on surgical removal and chemotherapy. The available evidence and results of publications concerning the application of radiotherapy are controversial. Accordingly, the international guidelines formulated by radiation oncology organizations have paramount interest in this particular pathology.
