Benign brain tumors represent a significant proportion of intracranial tumors diagnosed worldwide. Although they are not malignant, their location within the nervous system can cause neurological symptoms, hormonal changes, or compression of critical brain structures.
The most common benign brain tumors include:
- Meningiomas
- Vestibular schwannomas, also known as acoustic neuromas
- Pituitary adenomas
Over the past three decades, stereotactic radiosurgery has become one of the most important therapeutic tools for treating these tumors, allowing highly focused radiation to be delivered in a single session and without open surgery.
In Central America, the Centro Internacional de Cáncer (CIC) in El Salvador, led by neurosurgeon Dr. Eduardo Lovo, has developed an advanced radiosurgery program for the treatment of brain tumors. This program also holds certification from the International Stereotactic Radiosurgery Society (ISRS), recognizing compliance with international radiosurgery standards.
What is stereotactic radiosurgery?
Stereotactic radiosurgery (SRS) is a non-invasive treatment that delivers high-precision radiation with submillimeter accuracy to a defined intracranial target.
Despite its name, radiosurgery does not involve traditional surgery. Focused radiation interferes with the tumor cells’ ability to replicate while helping preserve surrounding brain tissue.
Most frequently used systems
- Gamma Knife
- LINAC-based radiosurgery
- CyberKnife
In most cases, treatment is performed in a single outpatient session, allowing the patient to return home the same day.
Radiosurgery for meningiomas
Meningiomas are the most common benign intracranial tumors. They originate in the meninges, the membranes that cover the brain.
Many meningiomas can be treated with surgery, but some are located in regions where surgery carries higher risk, such as:
- skull base
- cavernous sinus
- petroclival region
- parasagittal areas close to critical venous structures
In these cases, stereotactic radiosurgery has become a highly effective therapeutic alternative.
Reported clinical outcomes
- tumor control greater than 90%
- low neurological morbidity
- long-term stabilization of tumor growth
Radiosurgery for vestibular schwannomas
Vestibular schwannomas, also called acoustic neuromas, originate in the vestibular nerve.
Symptoms may include:
- hearing loss
- tinnitus
- balance disturbances
Radiosurgery is currently one of the most widely used therapeutic options for small and medium-sized tumors.
Clinical studies show
- tumor control between 90% and 95%
- high preservation of the facial nerve
- hearing preservation in some patients
Radiosurgery for pituitary adenomas
Pituitary adenomas are benign tumors that originate in the pituitary gland.
Functioning adenomas
These tumors produce excess hormones and may cause endocrine disorders depending on the hormone involved.
Non-functioning adenomas
These tumors grow slowly but may compress nearby structures and cause neurological or visual symptoms.
Radiosurgery is frequently used in:
- residual tumor after surgery
- tumor recurrence
- hormone-producing adenomas resistant to medical treatment
Clinical outcomes
- tumor control greater than 90%
- hormonal normalization in selected cases
- preservation of critical structures such as the optic chiasm
The role of Centro Internacional de Cáncer (CIC)
The Centro Internacional de Cáncer in San Salvador has developed a specialized program for treating brain tumors through radiosurgery.
The program led by Dr. Eduardo Lovo integrates:
- neurosurgery
- radiation oncology
- neuroradiology
- medical physics
This allows the center to offer treatment to patients from El Salvador, Honduras, Guatemala, Nicaragua, and other countries throughout Central America.
International ISRS certification
The International Stereotactic Radiosurgery Society (ISRS) promotes global standards in radiosurgery.
Its certification program evaluates:
- clinical experience
- treatment planning
- radiation safety
- quality control
- multidisciplinary processes
The Centro Internacional de Cáncer in El Salvador has obtained this certification, positioning it within the international network of accredited radiosurgery centers.
Key facts about radiosurgery for benign brain tumors
Frequently asked questions about radiosurgery for benign brain tumors
Can radiosurgery treat benign brain tumors?
Yes. Stereotactic radiosurgery may be used for selected benign tumors such as meningiomas, vestibular schwannomas, and pituitary adenomas, especially when high precision is required or when open surgery carries higher risk.
Does radiosurgery involve traditional surgery?
No. Despite its name, radiosurgery does not involve a surgical incision. It uses highly focused radiation to treat a defined intracranial target.
Which benign tumors can be treated with radiosurgery?
Benign tumors that may be treated with radiosurgery include meningiomas, vestibular schwannomas or acoustic neuromas, and pituitary adenomas.
Where can patients receive brain radiosurgery in Central America?
The Centro Internacional de Cáncer in San Salvador, El Salvador, offers an advanced brain radiosurgery program led by Dr. Eduardo Lovo and holds ISRS certification.
Conclusion
Stereotactic radiosurgery has transformed the treatment of benign brain tumors by offering a precise, minimally invasive alternative to traditional surgery.
Programs such as the one at the Centro Internacional de Cáncer, led by Dr. Eduardo Lovo, demonstrate that high-level radiosurgery programs can be developed in Central America while maintaining international standards recognized by the ISRS.
