CyberKnife treatment of brain metastases in Costa Rica

Introduction

Brain metastases are one of the most frequent complications in cancer patients. Today, there are highly precise, non-invasive alternatives such as CyberKnife robotic radiosurgery, which allows for the treatment of brain lesions without the need for open surgery.

At the Costa Rican Cancer Center - CyberKnife, we have state-of-the-art technology and a highly specialized multidisciplinary team to evaluate each case individually.

Who are candidates for this treatment?

This treatment may be an option for patients who present with:

  • Single or multiple brain metastases

  • Small or moderately sized lesions

  • Patients who are not candidates for surgery

  • Cases where the aim is to preserve neurological function

  • Patients who have already received previous radiotherapy

Each case must be evaluated by a specialized team.

What does brain radiosurgery involve?

Radiosurgery (RS) is a non-invasive procedure that delivers high-precision radiation directly to the lesion.

  • It does not require incisions

  • No hospitalization required

  • It is performed on an outpatient basis

  • High submillimeter precision

CyberKnife uses advanced robotic technology to track the patient's movement and ensure maximum accuracy during treatment.

How many sessions are needed?

Depending on the case:

  • 1 session (classic radiosurgery)

  • Up to 3–5 sessions in specific cases

The plan is customized according to the size, location, and number of injuries.

Advantages compared to other options

  • A non-invasive alternative to surgery

  • Lower risk of complications

  • Preservation of healthy tissue

  • Rapid recovery

  • Ability to treat multiple injuries

Possible side effects

Each case is unique. Side effects are usually mild and temporary, such as:

  • Mild headache

  • Fatigue

  • Localized inflammation

The medical team performs continuous monitoring to ensure safety.

Clinical evidence

Stereotactic radiosurgery (SRS) is a widely supported treatment for brain metastases, with high levels of local control and neurological preservation in multiple clinical studies.

Frequently Asked Questions

Does the treatment hurt?
No, the procedure is completely painless.

Do I need hospitalization?
No, it's an outpatient clinic.

Can I resume my activities?
In most cases, yes, in a short time.
