Foundation Dutch Uro-Oncology Study group (DUOS) is a multidisciplinary study group comprising 25 academic and regional hospitals in the Netherlands. Our key interest is initiating and collaborating in investigator as well as Industry initiated and sponsored clinical trials in urological cancers. The spectrum includes the entire range of metastatic and non-metastatic and phase 1-3 clinical trials as well as post-marketing (phase 4) health- economics studies. DUOS collaborates with other national groups, such as the Scandic Group, the Spanish Oncology Genitourinary Group (SOGUG), as well as the Prostate Cancer Clinical Trials Consortium in the United States.
In addition DUOS provides information on latest developments and ongoing research for health care professionals and patients. Study group members support patients seeking KOL second opinions. This may include enrollment of potential patients onto DUOS clinical research programs at one of the participating sites.
The group has received financial launching support from the Dutch Cancer Society. The board currently comprises two urologists: dr. Inge van Oort (Radboud UMC, Nijmegen) and dr. Joost Boormans (ErasmusMC Cancer Institute, Rotterdam); two radiotherapists: dr. Linda Kerkmeijer (Radboud UMC Nijmegen) and prof. Luca Incrocci (ErasmusMC Cancer Institute, Rotterdam); and two medical oncologists, dr. Andre Bergman (Netherlands Cancer Institute, Amsterdam) and Professor Ronald de Wit (ErasmusMC Cancer Institute, Rotterdam, founding Chairman of DUOS). DUOS is registered by the Netherlands Chamber of Commerce.
