Cancer cells are killed by intense ultrasound waves

There is a promising diagnosis and treatment method for prostate cancer patients who are diagnosed early, have not spread to other organs or have relapsed despite receiving radiation therapy: High Intensity Focal Ultrasound Method. prof. Dr. Can Öbek states that with this method, healthy tissues can be protected while cancerous tissues can be treated.

Prostate cancer is the most common type of cancer in men over the age of 50. It ranks second in cancer-related deaths after lung cancer. In short, it is both common and seriously threatening the life of the patient. As such, scientific research to increase early diagnosis and treatment opportunities continues at a rapid pace. The happy part of the job; In recent years, it is possible to detect prostate cancer at an early stage in parallel with the development of early diagnosis possibilities and the increase in awareness of the disease. Thanks to the increase in the early-stage diagnosis rate, there is a great increase in the rate of patients whose prostate tumor does not spread to other organs. But the search for new treatments continues for this patient group. At this point, focal treatment stands out as an important option among the new and developing treatment approaches discussed… Acıbadem Taksim Hospital Urology and Urooncology Specialist Prof. Dr. Can Öbek points out that while only the diseased area of ​​the prostate is treated with this method, healthy areas of the organ can be protected.

Healthy prostate tissues can be preserved

Today, the standard treatment in the treatment of early-stage prostate cancer is the complete removal of tumor-developing prostate tissue by using surgical methods. However, in the case of prostate tissue removal, side effects may develop, albeit at a low rate, even in experienced hands. The most feared of these side effects are urinary incontinence and sexual dysfunction. Therefore, the search for ideal treatment methods in the medical world continues unceasingly.

Symptoms, early diagnosis and new treatment options of prostate cancer

Stating that one of the most important and promising new developments in the search for the ideal treatment for prostate cancer patients, Prof. Dr. Can Öbek said, “While only the diseased area of ​​the prostate is treated with this organ-preserving method, healthy areas of the organ can be protected. In the method we started to implement, heat is used to kill cancer cells and it is aimed to destroy cancer cells with high heat.” Scientific medical data show that many patients who have been treated with the HIFU (High Intensity Focal Ultrasound) method have had successful results.

The patient can return home the same day.

An MR image is taken from the patient and the cancerous area is marked or its location is determined exactly with the smart biopsy technique. Then, the cancer cells are killed by giving high-intensity ultrasound waves to the cancerous area with the help of the HIFU device, which is a semi-robotic technology.

From the point of view of the patient-oriented treatment approach, the fact that the treatment with the HIFU method is a daily procedure provides an important gain for the patient. Regarding the application of this treatment method, which is completed in about 1-2 hours, Prof. Dr. Can Öbek gives the following information: “The cancerous area, which is marked by being seen in the MR image of our patient, or whose location is precisely determined by the smart biopsy technique, is destroyed with the use of semi-robotic technology. With this method, there is no need to make any incisions on the body. At the end of the procedure, without terminating the treatment, we can instantly monitor whether an effective treatment is performed in the desired area or not. If we think that there are still living cells, we also intervene in these cells before the process ends. The patient can return home the same day.”

Late diagnosis is an important problem in prostate cancer.

“Suitable patient” criteria

Stating that although it is still a newly developing method, the HIFU method has created extremely satisfactory results in terms of prostate cancer treatment. Dr. Can Öbek points out that this result can only be achieved in the right and well-chosen patients. Emphasizing that it is not an appropriate approach for all prostate cancer patients, Prof. Dr. Can Öbek said, “Today, it is generally preferred in newly diagnosed patient groups, which we define as low and medium risk groups. In choosing the right patient, criteria such as the aggressiveness of the cancer, how many foci and where it is located in the prostate are taken into consideration, and a decision is made after a detailed evaluation. Another patient group for which the method can be applied is those who have received radiation therapy before, but whose prostate cancer has recurred.
