Metastatic cancer is the kind of cancer we treat most often at CyberKnife Miami with great success and in a lot less time. Usually it only takes one to five treatments, compared to 10 to 25 treatments with traditional radiation therapy.
Metastatic cancer is a cancer that has spread from the original (primary) site to another place in the body.
CyberKnife, also known as stereotactic body radiation therapy (SBRT), has emerged as an excellent treatment option for those patients who are not surgical candidates, have failed chemotherapy treatment, or have run the course of treatments and been told there’s nothing left to do.
CyberKnife’s robotic arm and missile-guided image technology allows us to achieve a high level of accuracy by pinpointing a tumor’s exact location throughout the treatment, resulting in successful outcomes.
The sophisticated software uses X-ray images taken constantly during treatment to allow us to precisely deliver radiation to the tumor while minimizing damage to the surrounding healthy tissue and critical structures.
The CyberKnife system can continuously pinpoint and follow a tumor’s exact location as the patient breathes normally. This enables the CyberKnife to zero in on the moving tumor and focus multiple radiation beams from many different angles attacking the tumor. Standard radiation therapy can’t do that.
Each treatment typically lasts 30 to 60 minutes and is performed on an outpatient basis. If tumors come back, we often can treat them again.
The CyberKnife treatment is completely pain free. Patients dress comfortably in their own clothes and can bring music to listen to during treatment. Nothing will be required of the patient, except to relax. In fact, patients often sleep through the treatment.
There are generally only minimal side effects, if any, from CyberKnife treatments, which may include mild nausea and fatigue.
After completing the CyberKnife treatment, patients will schedule follow-up appointments.
Keep in mind tumors will not suddenly disappear. In fact, it could take several weeks or longer to determine the effectiveness of the CyberKnife treatment.
Response to treatment varies from patient to patient. Clinical experience has shown that most patients respond very well.
The number of treatments required depend on how many tumors are present and if they are in close proximity to each other. Research continues to demonstrate a 90 percent control rate for certain types of metastatic cancers treated with CyberKnife.
If you have metastatic cancer, it’s critical to understand your treatment options. To find out if you’re a candidate for life-saving CyberKnife radiosurgery, call the CyberKnife Center of Miami at (800) 204-0455.
