Germinomas of the brain are rare but potentially well-treatable tumors, where timely diagnosis and precise therapy strategy are particularly important. Treatment of brain germinomas in Israel is conducted according to an individual program, focusing on combinations of chemotherapy and high-precision radiation, allowing for sustained long-term remission. An individual protocol is developed for each patient, including modern neurosurgical methods, stereotactic radiosurgery, intensity-modulated radiation therapy, and gentle chemotherapy regimens.
Accurate diagnosis and the initiation of comprehensive antitumor therapy are provided to international patients in the shortest possible time, and the treatment process is led by a multidisciplinary team specializing in germ cell tumors. Numerous reviews indicate that patients appreciate the professionalism and attentiveness of the medical staff, clear organization, and assistance from the clinic's coordinator in resolving organizational issues. An important advantage of treatment in Israel is the affordable cost of services.
About the Disease
A germinoma belongs to the group of germ cell tumors that develop in the brain. Most often, intracranial germinomas form in areas of the brain where the pineal gland and pituitary gland are located. In germinomas, reproductive cells that typically migrate to the ovaries or testes during fetal development invade the central nervous system. Instead of developing into eggs or sperm, they continue to divide uncontrollably, forming an abnormal mass in one or more areas of the brain.
Germinogenic tumors of the brain are rare, but germinomas are the most common type of these neoplasms. They are usually diagnosed in children, adolescents, and young adults, more frequently in males. Although these tumors are often malignant, a positive prognosis is noted since they grow slowly and are easily treatable.
As of today, the causes of this disorder, which typically occurs no later than the first trimester of pregnancy, remain unclear. The risk of developing the pathology increases under the influence of the following factors:
- severe intoxication;
- viral diseases during pregnancy, such as influenza, herpes, measles.
Germinomas are characterized by the accumulation of cerebrospinal fluid (CSF) in the brain, which, combined with the pressure exerted by the tumor, leads to the following symptoms:
- headache;
- nausea and vomiting;
- coordination disorders (ataxia);
- vision problems (blurriness, double vision, and inability to look upward);
- sharp mood swings;
- inability to concentrate;
- increased fatigue.
Depending on the location of the germinoma, hormone-associated clinical signs may be observed:
- increased thirst and frequent urination (signs of diabetes insipidus);
- growth retardation;
- too early or late sexual maturation;
- drowsiness, lethargy.

Treatment Methods for the Disease
The Ichilov clinic provides comprehensive treatment for germinomas. Most germinomas can be treated with radiation therapy, enhanced by chemotherapy. The primary task of the doctors is to achieve maximum control over the disease while minimizing negative impacts on sensitive nervous tissue.
Radiation Therapy
Since brain germinomas are particularly sensitive to ionizing radiation, radiation therapy is the main method of antitumor therapy. At the Ichilov clinic, radiation sessions are conducted using modern gentle techniques that ensure targeted irradiation of the tumor focus while minimally affecting healthy tissues. In some cases, chemotherapy is recommended before starting the course of radiation therapy to reduce the size of the neoplasm and allow for a smaller dose of radiation.
Chemotherapy
This type of germ cell tumor is highly sensitive to chemotherapy agents. Additionally, in childhood, when this oncological disease is most often diagnosed, radiation therapy is contraindicated due to radioactive exposure. It has also been found that radiotherapy is ineffective when the tumor process is widespread. The Ichilov clinic uses modern low-toxicity types of chemotherapy agents that combine efficacy with low toxicity. Patients show positive dynamics without severe side effects typical of classical chemotherapy.
Surgical Treatment
Since the development of a germinoma is often accompanied by the accumulation of CSF in brain tissues, surgical removal of the tumor is combined with the installation of shunts that facilitate the restoration of normal cerebrospinal fluid drainage and the elimination of hydrocephalus. The Ichilov clinic performs ventriculoperitoneal shunting and endoscopic ventriculocisternostomy for shunting.
Stereotactic Radiosurgery
In cases where the patient has contraindications to neurosurgical intervention or difficult access to the neoplasm, stereotactic radiosurgery procedures are performed at the Ichilov clinic using the CyberKnife system. This method is based on destroying malignant cells through high doses of ionizing radiation. Patient safety is ensured by minimal damage to healthy tissues.

Diagnostic Methods for the Disease
For effective treatment of germinomas, it is essential to establish an accurate diagnosis as early as possible. The professionalism of diagnosticians and modern equipment allows for comprehensive examinations and diagnosis within three days.
First Day
After hospitalization, the patient is referred for a primary consultation with the attending physician. During the appointment, the neurologist examines the patient, reviews medical documentation, and prescribes necessary additional examinations.
Second Day
Conducting examinations:
- imaging studies (CT, MRI) – allow for the detection of the tumor, establishing its exact size, structure, and other features;
- echoencephalography – a method used to identify pathological signs of increased intracranial pressure and anatomical brain abnormalities;
- biopsy – obtaining tissue from the neoplasm for cytomorphological analysis, which allows for an accurate diagnosis;
- laboratory blood tests – identifying a high level of certain biologically active proteins characteristic of the disease.
Third Day
The council reviews the obtained results and, based on them, collectively establishes the final diagnosis and develops a comprehensive therapy program.
- Biopsy
- Computed Tomography
- Magnetic Resonance Imaging (MRI)
How Much Does Treatment Cost
The cost of therapy in Israeli clinics is favorably different from the rates of other popular medical tourism countries. The final price is determined only after the treatment is completed, while an approximate amount can be obtained from the clinic consultant.
Advantages of Treatment in Israel
- High qualification of neurosurgeons and neurologists.
- Equipping clinics with the latest technology.
- Use of advanced antitumor methods.
- Development of an individual treatment program.
- Reasonable prices.
Consultation with an Israeli doctor can be obtained without leaving home. To do this, you need to contact the clinic consultant, provide the required medical documentation, and arrange a time for the online consultation. The specialist will assess the accuracy of the diagnosis and the effectiveness of the therapy being applied, and recommend further treatment.
