What is intraoperative radiotherapy?

In targeted intraoperative radiotherapy (TARGIT for short), the treatment is performed directly after the surgery in the operating room after the tumor is removed. The tumor bed is exposed to the radiation and healthy tissue or skin surface has minimal exposure to radiation. The reasoning for targeting the tumour bed is that a very high percentage of recurrences affect the area where the original tumor was located. It is in the tumor bed that the ball-shaped radiation source (2.5cm - 5cm) is positioned in the tissue during targeted intraoperative radiotherapy.

The treatment is performed with the mobile INTRABEAM┬«  radiotherapy system (Carl Zeiss Meditec, Germany) using short-range X-ray radiation. Unlike traditional radiotherapy through the skin, the treated area is placed in direct contact with the radiation source under direct vision. Radiation can reach the target very precisely. The patient is still under anesthetic during the short exposure to the radiation (approximately 30 minutes).

 

Radiation Treatment during the surgery

1 and 2. The tumor is surgically removed.

3. The INTRABEAM┬« applicator tip is carefully positioned using surgical stitches in the area of the breast where the tumor was located  The INTRABEAM┬« radiation is applied for about 30 minutes.

4. After the treatment the applicator is removed and the incision is closed.
