Quo vadis cancer therapy is the title of Prof. Dr. Schirrmacher’s new book, a comprehensive guide on cancer. In the book different forms of treatment are discussed as well as how these were developed. The book highlights important findings from the fields of molecular biology, cancer biology, immunology, virology and physiology. A main part deals with new biological therapies from the last decades. An important section is the comparison of immune therapies with all other forms of cancer treatment.
The book is an appeal to the health care system to modernise the current forms of therapy and supplement these with new therapies available today. Cancer therapies should include more components from immune therapy, which reduces side effects and increases the long-term efficiency of the treatment. Take a look at the personal presentation.
Stefaan Van Gool presented the multimodal immune therapy of diffuse intrinsic pontine glioma (DIPG), a brain tumour occurring in children, at the annual meeting of the Society for Neuro-Oncology (SNO) in San Francisco. The SNO is a multidisciplinary organisation with a focus on advancing neuro-oncology through research and education.
Combination was the key word at this year’s function, e.g., between targeted therapies or between radiation and chemotherapy. Different combination options were also judged as gaining more importance in immune therapies: oncolytic viruses can be combined with dendritic cells vaccines or checkpoint inhibitors – or all three can be combined. The IOZK has already specialised in this approach in its compassionate use treatments.
The "International Journal of Molecular Sciences“ has published a review by Prof. Schirrmacher focusing on the role of Newcastle Disease Virus in tumor vaccinations.
- Immunobiology of Newcastle Disease Virus and its use for prophylactic vaccination in poultry and as adjuvant for therapeutic vaccination in cancer patients
The German publication „Deutsche Zeitschrift für Onkologie“ has published a bilingual review by Prof. Schirrmacher. It explains basics of immunotherapies and gives examples of strategies which have been particularly successful.
"Progress in the treatment of cancer is urgently needed to improve its efficacy. In the last 20 years, immunotherapy has emerged as a new biological method of treatment. Its impact has increased recently by the introduction of approved cancer immunotherapeutics. In comparison to chemo- and radiotheraphy immunotherapy is characterized by a higher specificity towards tumor cells."
The IOZK would like to answer some frequently asked questions here.
What does an individualised therapy mean?
The tumour-specific immune therapy is an individual, patient-adapted therapy. Through an autologous vaccine the immune system is activated and enabled to take up the fight against the cancer. This means that each individual patient receives a unique therapy tailored according to their physical disposition, genetic makeup, and medical history.
For this an autologous, patient-specific vaccine is produced according to the European Medicines Act and “Good Manufacturing Practice” (GMP) regulations for each individual patient as a personalised medicinal product. Thus patients at the IOZK receive the best possible immune therapy, tailored for them personally.
What is an “individueller Heilversuch”?
The IOZK treats patients under the German “individueller Heilversuch” regulation. There is no direct translation for this term or the German legalities associated with it, but the term can best be described as compassionate use treatment.
This approach is part of the medical therapeutic freedom. It represents a procedure which is primarily performed to the benefit of the patient when all other therapeutic options have been exhausted or which can be started earlier on one’s own account. Other than in clinical trials, the primary objective is not to gather general data on the patient’s response. There are no clinical values that need to be attained. A variation of this is a series of “Heilversuche”, where several of these treatments are performed in parallel or sequentially.
Does the IOZK adhere to formal regulations?
The tumour immunotherapy treatment at the IOZK is approved according to the Medicines Act §13. All services are charged according to the medical fee schedule (the German GebührenOrdnung für Ärzte – GOÄ).
Prof. Schirrmacher, Dr. Lorenzen, Prof. Van Gool and Dr. Stuecker published a review in Austin Oncology Case Reports which describes and explains the specific immunotherapy strategy that has been developed at the IOZK in Cologne.

Prof. Stefaan Van Gool is specialised in paediatric oncology – the treatment of children with brain tumours is a focus at the IOZK. A recent article in the Washington Post shows that this treatment is being noticed internationally by affected parents.
The Deutsches Ärzteblatt informs about a clinical study where patients with a Ductal Carcinoma in Situ (DCIS) were injected with multiple DC vaccines before their operation. The DC vaccines were proven to be safe, well tolerated, and effective: there were no detectable cancer cells in the tumour in one in four patients at the point of the operation.
The German Society for Hyperthermia held its 20th Congress from 30.09.2016 to 02.10.2016 in Berlin. Research findings as well as case studies were presented.
Dr. Bettina Weigelin (Department of Cell Biology, RIMLS, Radboud University Medical Center, Nijmegen/The University of Texas MD Anderson Cancer Center, Houston) presented video evidence from living cells showing that the interaction between immune cells and the attack of tumour cells at elevated body temperature shows a higher intensity.
Prof. Elizabeth Repasky, PhD (Professor of Oncology am Department of Immunology vom Roswell Park Cancer Institute) proved in her research that moderate whole body hyperthermia has a positive impact on immunological tumour therapy.
Prof. Dr. Marion Schneider (Sektion Experimentelle Anästhesiologie, Universitätsklinikum Ulm) presented her results on the on the immune reaction of macrophages under different different conditions elevating body temperature. This shows the positive influence of moderate hyperthermia, also in combination with antiinflammatory factors.
The first tumour immunology symposium at the Catholic University Leuven in Belgium took place from 12-14 September. The symposium focussed on results from current research and the therapy options resulting from these. In a presentation titled "Cancer cell death with a twist: Towards next-generation dendritic cell immunotherapy". Dr. Abhishek Garg (from the research group of Prof. Dr. Patrizia Agostinis, Catholic University Leuven), the IOZK was introduced as partner and centre for translation.
Prof. Schirrmacher has published a review on "Fifty Years of Clinical Application of Newcastle Disease Virus" in Biomedicines.

Stefaan Van Gool has joined the IOZK.
Stefan van Gool MD. PhD. is an internationally renowned immunologist who was actively involved in research at the University of Leuven in Belgium for the past 20 years. His research focus has been on:
- Paediatric neuro-oncology and histiocytic disorders
- Tumour immunology: preclinical research and clinical studies on brain tumours
- Long-term effects of chemotherapy
An important reason for his move to the IOZK was the manufacturing authorisation granted to the IOZK in May for the first autologous anti-tumour vaccine. “I am delighted to continue working in my area of interest. The manufacturing authorisation now makes it easier to provide patients with this therapy. At the same time, I realise that exciting new developments in preclinical research can be translated into clinical practice with the future-oriented team and network of the IOZK,” said Dr. van Gool.
New antibodies for immunological cancer therapy have been approved in Germany. These antibody therapies support tumour-specific immune cells fighting cancer cells. These are known as checkpoint inhibitor antibodies: PD-1 antibody (Nivolumab / trade name: Opdivo®) and PD-L-1 antibody (Pembrolizumab / trade name: Keytruda®),
