Many angiogenic and anti-angiogenic factors have been evaluated in terms
of DBGHL prognosis in the literature. The number of studies evaluating
these three factors at the same time is rare. In our study, the clinical
characteristics of both angiogenic factors VEGF, PDGFR_B and
anti-angiogenic factor thrombospondin-1 such as comorbidity at the time
of diagnosis, response to treatment and prognosis were investigated.
