title: Tasks and objectives of the German-Austrian-Swiss working group on tumors in the maxillo-facial region (DOSAK).
abstract: The German-Austrian-Swiss working group on tumors in the maxillo-facial region (DOSAK) comprises 61 hospitals in German-speaking countries. The working group is concerned with multicentre problems of tumor documentation, tumor diagnosis and tumor therapy. DOSAK can look back on almost 20 years of work. It therefore seems appropriate to report on the organization, methods and objectives and to make previous work as well as future tasks known beyond German-speaking countries.
