Brain tumor

Brain tumor is a group of various intracranial benign or malignant neoplasms that arise as a result of the initiation of the process of abnormal uncontrolled division of cells of the brain tissue, its membranes, blood vessels of the brain, cranial nerves and skull, or arising as a result of metastasis of the primary tumor located in another organ.

Epidemiology

  • Due to the many types of brain tumors, the incidence of the latter varies and depends on their type and the age of the patients
  • The incidence rate ranges from 10 to 15 cases per 100 thousand people
  • Among primary brain tumors, about 60% are malignant
  • The most common are meningiomas (22-23%), glioblastomas (24-25%) and anaplastic astrocytomas (20%)
  • About 10 - 30% of brain tumors are metastatic in origin
Epidemiology

Reasons

  • The cause of the development of neoplasms currently remains unclear
  • It is assumed that genetic defects, which can be inherited, as well as the impact of unfavorable environmental factors, play a certain role in the development of tumors

Clinical manifestations

Clinical manifestations of brain tumors depend on their location in a limited volume of the cranial cavity. The effect of the tumor (volume or chemical) on certain areas of the brain or the destruction of brain tissue in the tumor area (due to the growth of the neoplasm) determines the primary (focal) symptoms.

The most common symptoms:

  • Increasing neurological deficit (usually muscle weakness)
  • General cerebral symptoms (headache - one of the early signs, dizziness, vomiting)
  • Epileptic seizures

General information

Diagnostics

  • MRI of the brain with contrast - the main method
  • If necessary, the study is supplemented by special diagnostic methods: MR perfusion (assessment of blood flow), MR spectroscopy (assessment of the ratio of certain substances in the tumor in order to determine the approximate subtype of the tumor), MR tractography (construction of the brain pathways and the relationship of the tumor with these bundles), functional MRI (determination of the areas of the brain responsible for movement, speech)
  • Additional diagnostic methods: CT (assessment of changes in bones and anatomy of the skull), CT angiography (study of blood vessels), PET with various drugs

Treatment

  • The volume and method (or set of methods) of treatment are selected depending on the characteristics of the course of the brain tumor
  • The most effective and radical is surgical removal of the tumor
  • Stereotaxic radiosurgery (Cyber-Knife or Gamma-Knife) is possible for the treatment of small tumors (up to 3 cm)
  • If the tumor cannot be removed (in “inoperable” cases) or after its partial surgical removal, the patient is prescribed radiation, as well as chemo-, targeted (“aimed”) or immunotherapy

About doctor:

Fumin Ilya Alexandrovich

I would like to express my sincere and profound gratitude to the entire team: neurosurgeon Kirill Aleksandrovich Shaidurov, assistant Andronik Melikovich Demerchan, anesthesiologist Daria Aleksandrovna Postoyalko, and the entire medical staff at the K+31 clinic for the surgery to remove my herniated disc. Your exceptional professionalism was the key not only to my successful treatment but also to my return to a full, active, pain-free life. From the very first moment, it was clear that I was in the hands of true experts. Neurosurgeon Kirill Aleksandrovich Shaidurov not only explained the diagnostic results in detail and clearly, showing the whole picture in the images, but also listened attentively to my concerns and thoroughly described the planned procedure. This approach, combining deep knowledge and human compassion, immediately instilled confidence. The team's work during the surgery and postoperative period deserves the highest praise. The teamwork was flawless: from the anesthesiologist, who ensured my comfort and well-being, to the assisting staff. The quality of postoperative care was also outstanding—the staff was attentive and responsive, and the rehabilitation recommendations were clear and personalized. You are not just brilliant specialists; you are a team that gives people health and confidence in the future. Thank you for your invaluable work, skill, and professionalism.
I would like to express my sincere gratitude to neurosurgeon Ilya Aleksandrovich, who helped me during the most difficult period of my life. I came to him with a tumor and in a wheelchair he prescribed treatment and gave professional recommendations! His high professionalism, deep knowledge and confidence in every word and action helped me cope with a difficult diagnosis and believe that even in the face of a tumor, you can maintain dignity, strength and hope. He is not only a master of his craft, but also knows how to listen, explain, support - in a human, warm, genuine way. This is a rare combination - the talent of a surgeon and a big heart. Each meeting with him restored my faith that I am not alone, that they will help me and that everything is possible. Thanks to his participation, the pain has become less, and life goes on. Thank him for the light, for the knowledge, for the human attitude and for the fact that he exists.
