TARGIT - TARGeted Intraoperative Radiotherapy with INTRABEAM

The trend in oncological therapy is moving towards the targeted, risk-adapted and interdisciplinary treatment of tumors. INTRABEAM®, the innovative radiotherapy system from Carl Zeiss, is an ideal system for these requirements.

  • Localised tumor control – targeted effectiveness
  • Localised irradiation with a high radio-biological effectiveness
  • Practical mobility and fast workflow integration
  • Versatility of the clinical application
  • High quality of life outcomes and treatment comfort for patients

Targeted Radiotherapy for a Wide Range of Applications

Breast Cancer Treatment with Targeted Intraoperative Radiotherapy

Targeted intraoperative radiation with INTRABEAM is a risk-adapted individualised therapy. The 30-minute irradiation procedure is performed during the operation immediately after the tumor is excised. During this procedure, the isotropic dose distribution is applied directly into the tumor cavity using a spherical applicator in a way that ensures direct contact with the target tissue. Radiation is applied precisely to the area with the highest risk of tumor recurrence. The surrounding healthy tissue is spared.

Radiotherapy for Spinal Metastases with INTRABEAM

Treatment of spinal metastases with Kypho-IORT

For many cancer patients who develop spinal metastases in the natural course of their disease, percutaneous kyphoplasty and vertebroplasty are a valuable treatment option. By using intraoperative radiotherapy with INTRABEAM during kyphoplasty or vertrebroplasty, the metastasis can be sterilized and if necessary vertebra simultaneously stabilized, a solution that results in reduction of patient’s discomfort. It also restores mobility, significantly enhancing the patient’s quality of life. The first clinical trial experience of this approach has yielded very promising results.3

Radiotherapy for Gastrointestinal Cancer with INTRABEAM

Gastrointestinal Cancer Treatment

In cancer surgery, the primary goal is to completely excise the tumor. However, incomplete resection is sometimes the outcome. INTRABEAM can be used to improve local control of colorectal tumors. The value of INTRABEAM has also been demonstrated in the setting of laparoscopic hemicolectomy in patients with colon cancer and gastrectomy in patients with gastric cancer.4

Radiotherapy for Endometrial Cancer with INTRABEAM

Endometrial Cancer Treatment

In endometrial cancer – the most common malignancy of the female reproductive system – the use of INTRABEAM is also feasible and has some potential advantages compared to brachytherapy, which requires complex radiation protection. By comparison, INTRABEAM can be implemented without high investment costs.

First clinical trial evidence has proved that it is possible to create a homogeneous cylindrical dose distribution similar to 192Ir HDR afterloading, suggesting that INTRABEAM can be used effectively in this common female cancer.

Radiotherapy for Skin Cancer with INTRABEAM

Skin Cancer Treatment

The versatility of INTRABEAM is also displayed in the treatment of skin cancer. Particularly in the treatment of non-melanoma skin cancer, irradiation is an important therapy option. In a prospective study, it was shown that intraoperative radiotherapy with INTRABEAM was as effective in the management of non-melanoma skin cancer as conventional radiotherapy techniques. The well-known advantages of INTRABEAM – targeted radiation delivery, low shielding requirements, and cost effectiveness – also hold true for the treatment of skin cancer.5,6

Radiotherapy for Oral Cancer with INTRABEAM

Oral Cancer Treatment

Delivering a boost radiation intraoperatively with INTRABEAM has potential advantages in the treatment of oral cancers. After resection, the margins of the tumor can be sterilized immediately, which may have a positive impact on local recurrence rate. Additionally, the numerous sensitive structures in this anatomical region can be spared due to the steep fall-off of the low-energy radiation emitted by INTRABEAM. A geographical miss is unlikely since the applicator can be positioned directly in the tumor bed. First study data have convincingly demonstrated the value of this concept.7
