Clinic for Internal Medicine (Tumor Research)

Deputy Director:

Prof. Dr. med. Max Scheulen


Focus areas

Our clinic is one of the first of its kind dedicated to the pharmacological treatment of patients with malignancies and has been for decades.

Our clinical focus is on developing therapeutic strategies and applying pharmacological therapies as part of interdisciplinary treatment concepts for tumor patients, in particular with tumors of the lungs and the chest region, the gastrointestinal tract, the liver, the pancreas and biliary system, with breast cancer, ovarian cancer, with tumors of the head and neck region, with kidney, bladder, or germ cell tumors, with brain tumors, and tumors of bones and soft tissues. Another focus is on treating patients with cancers of unknown primary origin (CUP).

In addition to chemotherapy which continues to play an important role in tumor treatments, so-called targeted drugs such as monoclonal antibodies and tumor growth inhibitors have been developed. Our clinic has participated in introducing these agents into clinical practice, putting a different spin on modern cancer therapy. In addition, both the efficacy and safety of chemotherapy and radiation treatments have been significantly improved through concomitant medications and optimized drug combinations. The continued enhancement of these treatments as well as the development of new drugs in clinical trials is another focus area of the Clinic for Internal Medicine (Tumor Research). Last but not least, the palliative and pain relieving care of our patients, as well as the control of tumor complications, is particularly important to us. Physicians, nurses, and other professionals of the West German Tumor Center join us in providing these comprehensive, interdisciplinary services.
