However, long term follow up showed tumor regrowth in endometrial cancer (2/10) and the ovarian cancer.Conclusion The signaling system of embryonic axes has shown to impart polarization of individual cells in Drosophila. Normal cell polarity is essential for normal cell function. The effect of OuDP is rapid, which indicates a direct mending effect on cell function (ICST, 2015).Normalizing the tumor cells and microenvironment function may make tumor cells conform to the regulations with apoptosis, metastasis suppression, preventing uninhibited proliferation, minimizing angiogenesis and supervision by host immunological systems. Long term follow up of advanced cancer diseases treated with OuDP showed tumor regrowth after initial regression, which may be due to poor accessibility, insufficient efficacy or escape phenomenon. However, OuDP may be availed for an active prevention for cancer.Disclosure Nothing to discloseAbstract EP1290 Figure 1 The relation between OuDPt and stage II uterine endometrioid adenocarcinoma ER -
