Despite his tremendous clinical responsibility, Prof. Petry successfully succeeded in continuing his scientific work. Under his direction in cooperation with various health insurance companies (Deutsche BKK und Audi BKK), the first German HPV screening pilot project was started in Wolfsburg in 1999 (Wolfsburg Primary HPV Screening project: WOLPHSCREEN). During this pilot he included together with more than 30 office-based gynaecological practices 25,000 women in the age group over 30 years. This work has been visionary and has been the blueprint for the new screening directive in Germany beginning 2020 which will continuously improve screening for cervical cancer. His work will contribute to ensure that cervical cancer will be virtually eliminated in combination with the vaccine in a few decades. His scientific efforts has earned him numerous national and international awards and sponsorships.
