Sarcoma Research
In this line we aim to search for innovative targets of therapy, and look at side and late effects of treatment in sarcoma patients. In tumor material, linked to clinical outcome, we search for prognostics and predictive factors of therapy. In preclinical mouse models we evaluate effects of new targeted and conventional chemotherapy.
Psychosocial and Age related Oncology
Here we aim at findings factors of vulnerability of special patients groups or their family members. In 2009 Prof Judith Prins and I raised the so‐called Gammaraad to better define the final goal of all psychosocial research (which is defined as patient empowerment).
AYA research is performed within the frame work of the AYA platform, which I raised in 2009. This focuses on age related aspects of side effects and outcome of therapy. This AYA research has both psychosocial and basic research aspects.
