Technologies

Radiation Oncology departments of Acıbadem Hospitals Group use ionizing radiation in the treatment of cancer and conduct research and implementations to examine the effects of radiation on cancer and tumoral behavior.

TRUEBEAM

Truebeam STx, which incorporates advanced radiotherapy techniques used in cancer treatment, such as IMRT, IGRT, Gated RT, RapidArc, SRS and SBRT; offers fast, correct and precise radiation delivery to small tumors. Truebeam STx can be used for treatment of all tumors that require radiotherapy. The device is particularly preferred for treatment of small tumors of the head and the body, and tumors which pose a specific risk of adjacency to specific organs. As radiation delivery is focused on the target, healthy tissues are minimally affected. Fast radiation delivery system shortens duration of radiotherapy, and high image quality allows better positioning and precise radiation delivery.

Truebeam STx can conveniently be used in radiotherapy treatment for tumors in organs that require monitoring of respiration, such as the lungs, liver and breasts. As the device allows radiation delivery while monitoring respiration, it enables direct delivery of a high dose of radiation to the area where the tumor is located.

TRILOGY

Trilogy is a Linear Accelerator (LINAC) that comprises three different radiotherapy methods; namely, IGRT, IMRT and SRT/SRC. Trilogy is used for both diagnosis and treatment purposes, and provides significant advantages to the patient. IGRT allows image guided radiation therapy. IMRT allows intensity-modulated radiotherapy. Thus, the intensity of radiation in areas being treated can be adjusted to achieve an almost ideal dose distribution. While tumors are delivered highly concentrated doses of radiation, the surrounding healthy tissues are protected to a maximum extent. SRT/SRC technology allows point-by-point radiation. Using this technology, it is possible to better focus radiation on very small tumors of a few millimeters. Thus, while the tumor is delivered high doses of radiation, the surrounding healthy tissues are protected.

  • RAPIDARC

RapidArc is a cancer treatment device that can be used for treatment of all types of cancers, and that employs a high technology referred to as the "Volumetric Intensity Modulated Arc Therapy".Rapidarc reduces the duration of image-guided radiotherapy to 2 minutes. RapidArc is capable of delivering radiation while it is in motion, during a 360 degree rotation around the patient. This provides a much faster treatment, where the patient is less likely to move during treatment, eliminating potential risks that may arise due to patient's movement during the procedure.

GAMMA KNIFE PERFEXION

Used for non-invasive treatment of brain tumors, Gamma Knife Perfexion is acknowledged as the golden standard in radiosurgery. Facilitating intervention on areas of the brain that are difficult to access through conventional surgery, Gamma Knife Perfexion has minimal side effects. Moreover, precisely focused low dose radiation minimizes possible damage to healthy brain tissues. Gamma Knife Perfection therapy, which does not require general anesthesia, is completed within several hours and patients may return home on the same day.

CYBERKNIFE

CyberKnife is an advanced technological radiosurgery system that offers sub-millimeter precision in treatment of cancer anywhere in the body. CyberKnife is particularly used in multiple tumors that require complex surgery, and in treatment of tumors that cannot be surgically operated on. Its sub-millimeter precision minimizes potential damage to healthy tissues surrounding the tumor. CyberKnife monitors and tracks the patient's respiratory motion to correlate with the tumor's motion during the procedure, ensuring accurate radiation delivery. CyberKnife treatment is pain-free and does not require anesthesia. Patients can quickly return to their daily routines upon completion of the treatment.

Brachytherapy

Brachytherapy is an advanced method that is used before or after external radiotherapy to increase the radiation dose delivered to the tumor itself, for improved local control of cancer. It may be performed as curettage in patients with appropriate medical conditions. Brachytherapy involves delivery of radioactive sources to the tumors and target cells by means of special procedures, and allows limiting radiation dose within the surrounding area of the source.

Brachytherapy is used in treatment of gynecologic tumors, prostate cancer, head-neck tumors, bronchial tumors, and soft tissue sarcomas.

DIAGNOSIS AND TREATMENT SERVICES:​

Radiation Oncology departments of Acıbadem Hospitals Group have two primary subspecialties; namely, radiotherapy and radiosurgery.

Radiotherapy (Radiation Therapy)

Radiotherapy is among the fastest developing medical specialties over the recent years, in terms of technology. Used in combination with modern methods and products of advanced technology, radiation yields successful results in treatment of cancerous tissues.

What is Radiotherapy?

Also known as "radiation therapy", radiotherapy can be defined as the treatment of cancerous tissues and some benign tumors with radiation.

Radiation beams used in radiotherapy help stop further growth of cancerous cells, or kill such cells in the area being treated. Radiotherapy is frequently used in treatment of cancer. 60% to 80% percent of cancer patients are likely to undergo radiotherapy at least once, following their diagnosis.

How is the Treatment Method Determined?

The treatment method is determined based on a number of factors including; the patient's age and general health condition, as well as the type, extent and location of cancer that the patient is diagnosed with. Decisions with respect to treatment are taken through multi-disciplinary joint consultations with the participation of physicians of several different medical specialties. As treatment for each patient needs to be evaluated based on his/her actual conditions; an individual diagnosis and treatment process is planned and implemented for each patient.

Who are Included in the Treatment Team?

Radiation oncology specialist: The physician who decides on which areas of the body, and how much radiotherapy will be implemented. He/she is responsible for treatment and follow-up of the patient throughout the treatment process, implementing treatment changes as may be required depending on the tumoral changes, and evaluating any side effects that the patient may experience.

Radiation physicist: He/she is responsible for planning the radiotherapy treatment, ensuring that quality radiation care is maintained throughout the treatment process, coordinating technical assistance and maintenance processes for the medical devices and ensuring their safety.  He/she works in cooperation with the radiation oncology specialist on planning and implementation of the treatment.

Radiotherapy technicians: Radiotherapy technicians are professionals who are trained to use radiotherapy devices. They do not remain inside the treatment room during the radiation treatment sessions but they maintain constant communication with the patient through the screen located inside the control room. Radiotherapy technicians are in charge of ensuring that the patient is correctly positioned, operating the devices and taking assessment films during the course of the treatment.

Oncology nurse: The oncology nurse is the team member who most closely accompanies the patient, together with the radiation oncolog, throughout the treatment process. They act as a bridge between the physician and the patient, facilitating coordination of handling side effects, as well as what the patient should and should not be doing.

Secretariat: The secretariat unit is in charge of appropriately directing the patient, organizing appointments, creating and storing files, providing information on the cost of treatment and carrying out procedures as may be required in connection with the health insurance of the patient.

How Does Radiotherapy Work?

The radiation beams used in administration of radiotherapy treatment affect the DNA in cells of tumoral tissues. When DNA of cells is damaged to a certain extent, the cells lose the ability to reproduce. When such cells of the cancerous tissue die over time and are not renewed, the further development of cancer stops; allowing successfully treating several types of tumors. High dose of radiation administered during the radiotherapy sessions kills the cells or prevents further reproduction. As tumoral cells are likely to divide faster than most normal cells, radiotherapy is able to kill such cells to a considerable extent. Although normal cells are also impacted by radiotherapy to a certain extent, they recover in a fairly short amount of time with the help of special mechanisms that tumoral cells lack.

What are Radiotherapy Applications?

Radiotherapy is one of the fastest developing medical specialties over the recent years, in terms of technology. Today, the role of the Cobalt-60 unit which used to be widely used in cancer treatment in the past has been replaced by linear accelerator units, which are in widespread use in developed countries that lead advances in cancer treatment throughout the world. Acıbadem Health Group takes pride in utilizing modern and advanced technological methods of today's medicine. The Group is capable of offering all types of radiotherapy for its patients. There are two applications that particularly improve the efficiency of treatment: The first one is the three dimensional radiotherapy application where, the radiation dose to affect normal tissues is kept at a minimum level and the tumoral tissue is delivered the highest dose of radiation. The second one is systems that allow adjusting the intensity of radiation beams.
