Tinzaparin And Biomarkers After Neoadjuvant Treatment of Ovarian Cancer

Background: Previous findings have indicated antineoplastic properties of tinzaparin (Innohep®), a commonly used anti-coagulant. Earlier studies have mainly investigated the antineoplastic effects of tinzaparin in animal models and in human cell-lines. In this pilot study the aim is to examine the potential antitumoral effects of tinzaparin in vivo in women with epithelial ovarian cancer (EOC). Study objectives: Primary objective: The primary objective of the study is to evaluate the effects of tinzaparin on changes in levels of CA-125 in EOC patients who receive neoadjuvant chemotherapy (NACT). Secondary objectives: The secondary objective of the study is to explore the impact of tinzaparin on the dynamic of a spectrum of immunological and coagulation factors in EOC patients who receive NACT. Besides, the compliance of tinzaparin injections and adverse events caused by tinzaparin will be described.
