What we investigate

Prof. Dummer has developed a leading skin cancer center. This center offers best medical care and a network of clinical trials reaching from phase I to phase III. Locally he collaborates with basic research groups, which has resulted in translation work improving our understanding of cutaneous malignancies.

Our research in more detail

Based on his education in immunology, dermatology and oncology, Reinhard Dummer is focusing on the biology and the treatment of skin cancers. This includes cutaneous lymphomas with a special focus of cutaneous T-cell lymphomas, melanoma and epithelial skin cancers. He has pioneered the immunotherapy of metastatic melanoma in Switzerland. Checkpoint inhibitors, but also intralesional gene therapy approaches have been initiated in the Department of Dermatology over the last decades.

The clinical activities are paired with translational activities using biopsies or peripheral blood lymphocytes. Skin cancers are perfect neoplasias for this type of activity, because repeated biopsies are easy to perform. Recently, also fine-needle-aspiration has been used to follow cellular and molecular alterations induced by therapeutic interventions.

Immunotherapeutic agents are increasingly used for various tumor entities and lead to impressive reductions in metastases in some tumors. They act via the activation of immunological defense mechanisms, which, however, are not specifically limited to the tumor cells, but can also attack various organs. In this context, we are increasingly observing autoimmune phenomena in different organ systems, which must be carefully assessed by the relevant experts. An interdisciplinary expert group for immune oncology was therefore established at the University Hospital of Zurich to assist with specific questions in these fields.
