About
At the German Oncology Center (GOC), our work is grounded in three fundamental principles:
Close relationships with our patients
Personalised treatment
Radiotherapy services of the highest quality
These values guide every aspect of our approach—always.
Our center has invested in some of the most advanced technologies available in external beam and interventional radiotherapy. Combined with our team's commitment to empathy and human connection, our goal is to deliver the most effective treatment outcomes with the fewest possible side effects.
As a University Clinic, we are dedicated to remaining at the forefront of our field. This means:
Continuously integrating the latest scientific advances into our clinical practice
Actively participating in national and international research initiatives
Educating and training the next generation of oncology professionals
Through this website, we aim to provide clear, transparent information about our treatment methods, and most importantly, to introduce you to the people who form the heart of our department—our team.
Welcome to the Department of Radiation Oncology.

Equipment
Technology – External Radiotherapy Unit, German Oncology Center (GOC)
The External Radiotherapy Department at the German Oncology Center (GOC) is equipped with two state-of-the-art linear accelerators (LINACs): the Elekta VERSA HD and Elekta SYNERGY, as well as a General Electric (GE) CT scanner. This advanced equipment enables the precise planning and delivery of external beam radiotherapy with exceptional accuracy, safety, and efficiency.

About
External Beam Radiotherapy (EBRT)
External Beam Radiotherapy (EBRT) is a highly effective method of cancer treatment that delivers high-energy radiation to tumours with the goal of destroying cancer cells while minimising damage to surrounding healthy tissue.
Treatment is delivered using a Linear Accelerator (LINAC)—a specialised machine that produces high-energy X-rays or electrons. These are directed to the tumour from multiple angles with extreme precision, maximising therapeutic benefit and protecting healthy organs and tissues.
To enhance accuracy, LINACs are equipped with multi-leaf collimators (MLCs)—thin lead leaves that move dynamically during treatment. These leaves shape the radiation beam to match the exact contours of the tumour, ensuring optimal targeting as the machine rotates around the patient.
Treatment Planning and Delivery
A successful radiotherapy treatment plan is the result of multidisciplinary collaboration. At the GOC, a dedicated team of:
Radiation oncologists
Medical physicists
Dosimetrists
Radiation therapists
work together to design a highly individualised and refined treatment plan for each patient. This planning process may take several days, and typically there is a one-week interval between the initial planning session and the start of treatment.
All external radiotherapy treatments are performed in radiation-shielded treatment rooms, where high-energy X-rays are accurately delivered using our state-of-the-art LINAC systems.

About
Interventional Radiotherapy – BrachytherapyPrecision Radiation from the Inside Out
The Interventional Radiotherapy – Brachytherapy Clinic at the German Oncology Center (GOC) is internationally recognised for its comprehensive, advanced, and highly effective treatments, supported by cutting-edge technology and decades of clinical expertise.
What Is Brachytherapy?
Brachytherapy is a form of internal radiation therapy, where radioactive sources are placed inside or next to the tumour. This is in contrast to External Beam Radiotherapy (EBRT), where radiation is delivered from outside the body.
In High-Dose-Rate (HDR) Brachytherapy, fine needles or catheters are inserted into or adjacent to the tumour, using advanced image guidance such as CT scans, MRI, ultrasound, or a combination of these techniques. The catheters are then connected to a treatment unit containing the radioactive source—typically Iridium-192. The source travels through the catheters and delivers high doses of radiation to the tumour, based on a personalised radiotherapy plan developed by our expert Medical Physicists.
This highly targeted method maximises the radiation dose delivered directly to the tumour, while minimising exposure to surrounding healthy tissues, making it one of the most precise and effective forms of radiotherapy available today.
Clinical Applications and Effectiveness
Brachytherapy can be used alone or in combination with external radiotherapy, depending on the type and stage of cancer. It has proven to be especially effective in the treatment of:
Prostate cancer
Cervical cancer
Breast cancer
Soft tissue sarcomas
Liver and lung metastases
The brachytherapy techniques applied at the GOC have been developed over 25 years of clinical research and innovation by Professor Dimos Zamboglou and his multidisciplinary team in Germany. These techniques enable the safe delivery of much higher radiation doses than traditional external radiotherapy—doses that are often necessary to achieve long-term local tumour control.
Proven Outcomes
The brachytherapy methods practised today at the German Oncology Center have achieved remarkable clinical results, particularly in the treatment of prostate, cervical, and breast cancer. These outcomes have been published in peer-reviewed medical journals and are widely cited in the international oncology community.

The Department
Comprehensive and Personalised Cancer Care – Radiotherapy Department, German Oncology Center (GOC)
At the German Oncology Center (GOC), we operate a fully integrated Radiotherapy Department, where we apply some of the most advanced and specialised treatment techniques available in modern cancer care.
From your very first visit, you will experience the dedication of our highly trained team of specialists—including radiation oncologists, physicists, radiographers, nurses, and patient coordinators. Our entire team is focused on you.
We design personalised treatment plans based on each patient’s biological, anatomical, and clinical characteristics, ensuring maximum precision and therapeutic effectiveness. At the same time, we take care of all practical aspects of your experience, helping you feel safe, supported, and comfortable throughout your treatment journey.
Our Department is in close cooperation with, and supported by Molecular Biology and Genetics clinics, and our in-house Medical Oncology, Diagnostic and Interventional Radiology (3D-Ultrasound, CT Scan and MRI), Nuclear Medicine and Medical Physics Departments.
In line with international guidelines, we hold regular Oncology Board Meetings of all associated medical disciplines, so as to ensure that decisions concerning personalized treatments are objective and reliable.
