    4. Discussion
    A key finding of this 3X FLAG Peptide study is that statin use is associated with de-
    creased risk of VTE in women with endometrial cancer. Simvastatin
    use, in particular, seems to greatly reduce the risk of VTE. Moreover, a
    possible synergistic effect of dual statin/aspirin use on VTE risk reduc-
    tion may be suggested. This study also suggests that obese women
    and those with aggressive tumor characteristics may benefit from statin
    independent. Statin use was associated with an approximately 60% re- use to decrease VTE risk.
    pirin use did not retain an independent association with decreased VTE strating reduced cancer-related thrombosis with statin use [7–10].
    The joint effects of combined statin and aspirin use were examined various cancer types, and endometrial cancer-specific data has been
    pirin. Among 219 aspirin users, there were 127 (59.6%) women who tion between statin use and decreased VTE risk in the endometrial can-

    lowest incidence of PE among the groups, although this did not reach sociation between rosuvastatin use and VTE. These results suggest that
    statistical significance (0% for dual statin and aspirin use, 1.0% for statin effects on VTE risk may vary based on the type of statin used and the
