ABCSG-Publications (peer reviewed) 2016-2020

The publication of study results is an essential mandate of the ABCSG. Therapy improvements can only be made accessible to the entire medical-scientific community through publications. As a result, our knowledge of cancer is continuously increasing and the chances of winning the battle against it increase.

The publications listed here are the result of many years of successful work by the ABCSG.
