Radiosurgery is a surgical procedure aimed at\nthe complete and precise destruction of a\ndefined target volume containing abnormal or\nnormal cells by a single high-dose radiation\ntreatment without damaging surrounding tissue.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

\n
\n \n \n How does it differ from radiotherapy?<\/span>\n\n \n

During radiotherapy, the patient is treated\nseveral times with low-dose radiation beams.\nThe treatment can last up to a month. It is\nusually used to treat lesions where the aim is to\ntreat as large a volume as possible and where\nthe irradiation does not require high precision.\nRadiosurgery uses a single high-dose radiation\nto treat the lesion with millimeter precision.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

Inside the device, a charge of 30 Co-60 isotopes\nis placed along a hemisphere. Each of these\ncharges rotates around a circular arc about an\naxis parallel to the longitudinal axis of the\ncontrol table. The gamma-ray beams emerging\nfrom the charges are directed to a common\npoint, the so-called focal point. At the focal\npoint, the effect of the beams, which come\nfrom many directions but are each of low\nintensity, is multiplied, enabling the beam to\nproduce the desired biological effect at that point. The size of the focal point depends on\nthe size of the collimators, which are located\ninside the device and in front of the beam\nsources and are variable in size. The radiation\nexposure of tissue outside the focal point is\nsignificantly lower than that of the treated area.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

A form of radioactive radiation. During the\ndecay of the Co-60 isotope, two high-energy\nelectromagnetic waves are produced, 1.17MeV\nand 1.33MeV. These ionizing rays, which are\ninvisible to the eye, are called gamma rays.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

The device, its operation, the radioactivity of\nthe radiation sources, the mechanical accuracy,\nand the computer and software used for its\ndesign are continuously checked and tested by\na team of physicists under a rigorous quality\ncontrol program.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

The treatment triggers various biological\nprocesses in the treated area, which, depending\non the dose and the lesion, may include cell\ndeath, scarring, vascular occlusion, acute\ninflammation, and brain edema.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

No, the effect of the intervention is not\nimmediate in the vast majority of cases and is\nhighly dependent on the radiation dose\ndelivered and the radiosensitivity of the\nformula. For the different processes, the reduction in size, vascular occlusion, and\nfunctional change takes a longer or shorter\ntime. The development of the effect can take\nfrom months (1-2 months) to years.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

The course of treatment is the same, but\ndifferent conditions are treated with different\ndoses depending on the desired effect and the\nfunction and sensitivity of the surrounding\ntissue.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

Fainting, headache, pressure in the head,\nnausea, general malaise, and neurological\nsymptoms due to brain edema may occur. Most\npatients have no symptoms.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

Not usually, but in some cases, anti-epileptic\ndrugs or steroids are recommended to reduce\nbrain edema. Sometimes, mood stabilizers are\ngiven to reduce symptoms during treatment\nand to reduce feelings of confinement. The\npatient will continue to take their regular\nmedication.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

Gamma knife treatment is a non-invasive\ntreatment alternative to traditional cranial\nexploration techniques. It provides a one-off\ntreatment for many patients who have\npreviously been in doubt about undergoing any neurosurgical intervention at all. The treatment is associated with fewer risks, complications, morbidity, and mortality compared to traditional surgical procedures. Patients also recover more quickly. If necessary, oncological treatment can be continued after a few days.\nThe treatment is less stressful for the patient's body and involves much less pain than open surgery. It does not require anesthesia in adults and can be performed in patients with poor general health where anesthesia has previously made this impossible.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

\n
\n \n \n How long have these radiosurgical procedures\nbeen performed?<\/span>\n\n \n

The principles of the method were developed\nby neurosurgeon\u00a0Professor Lars Leksell<\/i>\u00a0(Department of Neurosurgery, Karolinska\nUniversity, Stockholm). He developed the\nprinciples 50 years ago. The first treatments\nstarted in the second half of the 1960s, and the process spread worldwide in the second half of the 1980s with the development of CT and MR equipment. Currently, there are hundreds of radiosurgery centers around the world. Almost half a million patients have been treated in recent years. In Hungary, LINAC-based stereotaxic point irradiation has been performed in Budapest since the early 1990s. In June 2007, Hungary's first Gamma Radiosurgery Center was inaugurated at the University of Debrecen Medical and Health Sciences Center. Since then, patients have been treated continuously.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

In a few cases, the appearance of a malignant\ntumor that had not previously existed was\ndescribed, but this can occur with any\nradiotherapy. The likelihood is extremely low.\nIn very rare cases, unexpected tissue necrosis,\nneural pattern damage, and very marked brain\nedema and its sequelae may occur.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

\n
\n \n \n Can the treatment be repeated?<\/span>\n\n \n

As the irradiation is targeted only at the\naffected area, the treatment can be repeated or\nextended to other areas if necessary.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

\n
\n \n \n The tumor is in a location that cannot be\nremoved by open cranial excavation. Can the\npatient be treated with radiosurgery?<\/span>\n\n \n

It depends partly on the pathology and its\nlocation, but theoretically, there is no place\ninside the skull that gamma rays cannot reach.\nOf course, each case needs to be considered on\nits own merits.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

\n
\n \n \n They operated but could only remove part of\nthe tumor. Is treatment possible in such a\ncase?<\/span>\n\n \n

For certain pathological processes, radiosurgery\ncan be used not only instead of open surgery,\nbut also in combination with it in addition to it.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

\n
\n \n \n I have had radiation treatment before. Does\nthis exclude radiosurgery?<\/span>\n\n \n

It does not rule it out, even if the patient has\npreviously received full cranial irradiation.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n
