The Impact Factor, often abbreviated IF, is a measure reflecting the average number of citations to recent articles published in science and social science journals. IF is calculated by dividing the number of citations in the Journal Citation Reports year by the total number of articles published in the two previous years. High impact factor for a particular journal implies good number of citations and quality of work. Because of the open access journals, impact factors are improving. Open access journal articles are essentially peer-reviewed and available for access through the directory of Open Access journals. Each open access journal delivers the latest updates in the respected research area in various formats so that subscribers can access the same through various options. With the growing number of scientific enthusiasts and readers by a large margin, the efficacy of open access publishing has witnessed an assertive impact.
Radiotherapy uses radiation, such as x-rays, gamma rays, electron beams or protons, to kill or damage cancer cells and stop them from growing and multiplying. It is a localised treatment, which means it generally only affects the part of the body where the radiation is directed. Primary spinal canal tumors are a diverse group of neoplasms constituting 4% of all central nervous system tumors. They can be broadly classified into intradural and extradural tumors. MRI is the most useful neuroimaging modality. A histopathology is mandatory in most of the cases. The primary modality of treatment is surgery. No adjuvant treatment is required if a complete excision can be done. However, in a significant number of patients, complete excision may not be feasible in view of the possibility of significant neurological complications. Hence, external radiotherapy plays an important role in the management of these neoplasms. Radiotherapy may be given as a definitive treatment or more commonly as an adjuvant. Advancements in technology have made the delivery of high precision radiotherapy like three-dimensional conformal radiotherapy, intensity modulated radiotherapy and stereotactic radiosurgery feasible and safe. The favourable prognostic features are feasibility of achieving a complete resection, low grade, caudal location, small volume disease and histology.
