What is tumor ablation? Can cancer be treated without surgery? How successful are these methods? Apart from cytostatic therapy, are there other alternative methods of treatment? This morning, we will receive an answer to these and many other questions in the program "Sloboden Pechat" from the head of the Department of Radiology, Oncology and Nuclear Medicine from the private hospital "Acibadem Sistina", doctor Aleksandar Gjoreski.

Gjoreski says he is an interventional radiologist who deals with minimally invasive treatments.

– I am a subspecialist in interventional radiology. This means that we not only diagnose, but to a large extent treat certain diseases. Interventional radiology, as the years go by, is getting bigger and bigger, so several sub-branches have already formed here. Thus, we divide it into non-vascular interventional radiology, vascular interventional radiology, interventional oncology and the most specific part that deals with the treatment of changes in the head, that is, the brain, that is neurointerventional radiology, says the doctor.

His focus, a narrower field of interest, is interventional oncology, where minimally invasive tumor treatments are performed.

- In recent years, interventional oncology has emerged as the third pillar in the treatment of cancer. That means, if the first pillar is classical oncology and radiotherapy, the second pillar is surgery, the third pillar, which is equally important, is interventional oncology. Here we find ourselves with several different types of treatment, starting with invasive diagnostics of tumors. What does that mean? This means that if a patient has a suspicion of cancer, which has been established through any of the classical imaging such as computed tomography, magnetic resonance, ultrasound, X-ray and so on, the oncologist needs a pathohistological confirmation before starting therapy. And here we find ourselves with different types of biopsies. The interventional radiologist, using some tools, CT or ultrasound or fluoroscopy, can get to the deepest parts of the human body without surgery, without cutting, without an incision and remove a piece of tissue, says Gjoreski.

He explains that if earlier interventional radiologists treated only liver tumors, malignant tumors such as hepatocellular carcinoma, nowadays they also treat liver metastases.

– We can treat colon cancer metastases, but also metastases from various other types of cancer, such as breast cancer metastases, kidney cancer metastases and so on. We do that through ablation, which is a minimally invasive technique, and on the other hand, through the direct application of cytostatics in the liver, a method called embolization, that is, chemoembolization, says the doctor.

He says they do prostatic artery embolization in patients with enlarged prostates.

- Patients do not have to go to classic surgery. Naturally, it is the method of choice and will remain so. However, in a certain selected group of patients who cannot be operated on for various reasons, we should treat them and reduce their prostate size using a minimally invasive method - says Gjoreski.

This is the only such department in the region, not only in the country. Since October last year, they have been doing cryoablation, a method that destroys tumor cells by freezing the tissue.

– A thin needle is inserted, under computed tomography, one or more needles, depending on the size of the tumor, they are connected to a special device, which we have in our department, it produces extremely low temperatures directly in the tumor tissue, from minus 40 to minus 20 and that's how cancer cells die, says the radiologist.

The biggest tumor they treated was 8 to 9 centimeters. The intervention costs about 5.000 euros, and the patient goes home after one day.
