First revolutionary tumor freezing technique performed in Croatia 

ZAGREB, 10 May (Hina) – The Sisters of Mercy Hospital in Zagreb was the first in Croatia to perform the freezing of a malignant breast tumor, which represents an important innovation in the field of minimally invasive procedures for oncology patients.

Cryoablation, or freezing of tumours, has been used in that hospital for two years, but until now this procedure was used to treat kidney, lung and bone cancer, and from today it will also be used for breast cancer, the hospital announced on Wednesday.

“Cryoablation is a technique that freezes only harmful tissues and tumours and destroys them in a targeted manner, without implications for the surrounding healthy tissue,” Luka Novosel, head of the Interventional Radiology Department, explained.

The procedure consists of precise guidance of needle probes through the skin, which are placed in the tumour using an ultrasound device, followed by creating an ice zone, up to three centimetres in diameter, which destroys tumour cells.

“With this procedure, the remaining part of the patient’s breast is spared, given that no metastases were found,” Novosel pointed out.

It is a procedure suitable for patients who are not ideal candidates for classic breast resection due to age and comorbidities or the risk of anaesthesia and for tumours up to two centimetres or smaller metastases.

An additional advantage of breast tumour cryoablation is that it is performed on an outpatient basis, it is painless and lasts one hour, after which the patient can go home, the hospital’s director Davor Vagić underscored.
