Hadassah constantly introduces new radiotherapy

Radiotherapy (radiation therapy) uses the properties of ionizing radiation that can penetrate the body tissue and destroy cancer cells.

Hadassah uses the most advanced radiotherapy technologies and most of those are used only in Hadassah Medical Center.

To learn more about the latest radiotherapy technologies that are used in Hadassah or to consult with leading radiologists and oncologists in Israel, contact our staff.

  

Unique radiation therapy at the Hadassah Clinic

Innovative Linear Accelerator

In 2016 the clinic has installed the latest and so far the exclusive Israeli radiation therapy apparatus Novalis TrueBeam STx 2016.

This linear accelerator is a radiating device created using cutting-edge technologies in radiation medicine.

The machine has such a precision that is not available to previous models of linear accelerators which are used in the other Israeli clinics. The new Novalis TrueBeam makes the irradiation process safer and faster: healthy tissues are left intact therefore the radiation dose is significantly increased. This reduces the duration of the usual course by 30-50% (in some cases, from 2 months to one week!).

In case the tumor is close to the vital organs or the nervous system, the precision of exposure is especially important as any undesired damage can result in very serious consequences.

The machine is equipped with many innovationonal parameters such as a perfect targeting system which can detect a tumor itself and deliver precise radiation. A control system for breathing and other body movements allow one to take into consideration the slightest displacement of the body and not harm the patient's health, by stopping irradiation in time and resuming it after operational adjustment.

"The system is equipped with video sensors responding to the slightest body movements when breathing" - explains Prof. Mark Wigoda, Head of Radiotherapy Unit - The system stops irradiation upon the reception of a motion signal and then again directs the beam to the tumor. Also, the new system includes a special bed that allows you to achieve the most precise position of the patient's body during irradiation. "

Spinal Radiation Therapy Revolution

Hadassah radiologists were the first in Israel to start using the Brainlab Spine SRS software. It allows to increase the radiation precision for the metastases located near the spinal cord up to 3-4 fold.

This innovation is very important because of the danger of injury to the spinal cord during radiation therapy for those metastases that are located in spine proximity. The consequences of any mistake can be very diverse and very severe. Also kidneys can suffer from this form of radiation, which is very dangerous for the patient with cancer who is already in serious condition.

Spine SRS program avoids dangerous and complex surgery by replacing it with radiosurgery. And the overall treatment time is significantly shorter compared to conventional surgery.

Thanks to Spine SRS, radiologists can bring the irradiation process to a more complete combination with the three-dimensional model created using state-of-the-art MRI and CT devices. The exposure precision of Spine SRS is less than 1 millimeter. And it ranged from 3 to 6 mm before the introduction of this program.

The radiation therapy using Spine SRS is carried out  by a multidisciplinary team comprised of the leading neurosurgeon and the specialist in medical imaging under the direction of the chief radiologist Dr. Amichai Meirovitz

 Spine SRS radiotherapy is intended for patients with solitary spinal metastasis. A preliminary operation is necessary to "push" the neoplasm away if it is located too close to the spinal cord, eliminating the unwanted risk.

  

The main types of the external radiotherapy carried out  in Hadassah clinic

The clinic conducts several types of external radiotherapy procedures:

Three-dimensional conformal radiotherapy:  the damage to neighboring healthy tissues is minimized by providing the optimal amount of radiation. The procedure is performed once a day for a week or several weeks depending on the patient's health conditions.

Stereotactic radiosurgery (SRS): single high-energy irradiation of the pathological lesions.

Fractional stereotactic radiotherapy (FSR): high-energy irradiation of the pathological lesions in the head area, carried out for several days.

The total exposure of the whole organism (TBI): the effect is achieved both by the direct irradiation of the multiple tumors and by exposure to the hematopoietic and lymphoid systems.

Intensity-Modulated Radiotherapy (IMRT): is an advanced mode of high-precision radiotherapy that allows setting the intensity of the radiation beam to conform to the three-dimensional (3-D) shape of a tumor. Thus, it is possible to maximize radiation doses within the tumor while also minimizing the dose to adjacent normal tissues.

Hadassah Brachytherapy Level is one of the highest in Israel

Brachytherapy is a procedure that involves placing radioactive material directly at the site of the cancer tumor.

Brachytherapy at the Hadassah Clinic is basically used for the treatment of prostate cancer, cervical cancer, oral cancer and malignant eye tumors. The procedure is also carried out in Israel for the treatment of other oncological diseases.

As is known, half of the brachytherapy success depends on the thorough planning and control performed by the medical imaging devices - CT, MRI or ultrasound.

The clinic utilizes state-of-the-art generation of tomographs and ultrasound equipment. Machines are maintained by the experienced doctors who have been trained in the largest cancer centers in Western Europe, Canada and the US.  The decryption of the results and monitoring is carried out by leading Israeli oncologists, such as Dr. Amihai Meirovitz, Head of Focused and Stereotactic Radiotherapy Unit with experience exceeding 25 years.

The procedure where a sealed radiation source is placed inside the area requiring treatment is carried out by the well-known surgeons: urologists, gynecologists, ophthalmologists, and other specialists, depending on the necessary radiation application.
