Masarykův onkologický ústav has successfully implemented a modern medical procedure known as electrochemotherapy to treat spinal tumors. This marks the first time the institute has utilized the method, and This proves only the third such instance recorded in the Czech Republic.
The Mechanism of Electrochemotherapy
The procedure is designed to overcome a common hurdle in cancer treatment: the difficulty standard chemotherapy has in penetrating certain bone tumors. To solve this, doctors utilize a two-step process involving specialized needles that act as electrodes.
First, the patient receives a minor dose of chemotherapy, administered either intravenously or directly into the tumor. Following this, short electrical discharges are sent through needles positioned near the vertebra.
According to Jan Křístek, primär of the radiology department, these discharges create microscopic holes in the membrane of tumor cells. This allows the medication to slide inside; once the discharges stop, the holes close, trapping the drug within the tumor to destroy it.
Clinical Significance and Patient Impact
This method is described as a gentler and improved form of chemotherapy. It provides a critical alternative for patients with spinal metastases, particularly those who have already exhausted their permitted doses of radiation.
The primary goals of the intervention are to stop tumor growth and provide relief from the back pain typically caused by metastases. Klára Jirkovská, spokesperson for the institute, noted that patients usually experience pain relief within a few weeks of the procedure.
Specialized Care and Future Outlook
Because of its complexity, the procedure is only performed at specialized facilities. Masarykův onkologický ústav is able to offer this treatment through its new, state-of-the-art interventional oncology center within the radiology department.
The intervention is performed under general anesthesia and typically requires only a single treatment session. As a very modern method, it may be gradually introduced into wider clinical practice.
Frequently Asked Questions
What is the primary advantage of electrochemotherapy over standard chemotherapy?
Standard chemotherapy often struggles to penetrate certain tumors in the bones. Electrochemotherapy uses electrical discharges to create microscopic holes in tumor cell membranes, ensuring the medication reaches and remains inside the cancer cells.
Who is the ideal candidate for this procedure?
This method is a hopeful option for patients with spinal metastases, especially those for whom standard treatment is insufficient or those who have already exhausted their radiation doses.
How is the safety of the patient ensured during the operation?
The procedure is conducted under general anesthesia and under the control of CT imaging, which allows doctors to ensure the needles avoid the nerves and the spinal cord.
Do you believe that the wider adoption of interventional oncology could significantly change the quality of life for patients with bone metastases?
