[Stereotactic radiotherapy of spinal hemangioblastoma].

Hemangioblastoma (HAB) is a benign, richly vascularized tumor that accounts for 2-6% of all spinal cord neoplasms and ranks third in the structure of intramedullary space-occupying lesions of the spinal cord. Hemangioblastoma may occur sporadically or, in approximately 30% of cases, as part of the clinical picture of a hereditary disease, von Hippel-Lindau disease. The aim of this study was to evaluate the efficacy and safety of stereotactic irradiation of hemangioblastomas of the spinal localization in patients with sporadic and von Hippel-Lindau-associated hemangioblastomas The results of stereotactic radiotherapy were evaluation of 210 spinal hemangioblastomas in 74 patients.

[The accessibility of oncologic medical care in the Russian Federation in context of radiotherapy: The last years analysis].

The accessibility of medical care plays important role in ensuring basic human needs and means unimpeded access to all services in national health care system. It is conditioned by: balance of necessary volumes of medical care of population, national medical and financial resources, availability and qualification of medical personnel, rendering of necessary types of medical care in territories, possibility of patient free choice of physician in charge and medical organization, available transport possibilities, level of public education on health promotion and diseases prevention. The availability of radiotherapy, as an integral part of oncological care, is determined by possibility of its timely delivery to all patients and is conditioned by total number of oncological centers equipped with radiotherapy equipment and qualified specialists.

Radiosurgery for cerebral cavernous malformations: a systematic review.

Background: Stereotactic radiosurgery (SRS) for cerebral cavernous malformations has been used for more than 30 years. However, indications for this method and outcomes are still discussable.

Objective: To analyze available literature data on SRS for cerebral cavernous malformations with assessment of indications for treatment, radiation parameters, radiological and clinical complications and outcomes.

Comparative analysis of combined treatment methods for patients with single brain lesions.

Unlabelled: Primary brain metastases are common in oncology. Preoperative stereotactic radiosurgery followed by surgical resection is a perspective approach.

Objective: To evaluate own experience of preoperative radiosurgery followed by surgical resection (RS+S) of metastasis regarding local control, leptomeningeal progression, surgical and radiation-induced complications; to compare treatment outcomes with surgical resection and subsequent radiotherapy (S+SRT).
