“…Previous studies indicated that preoperative hematologic parameters obtained from complete blood count (CBC) might serve as prognostic biomarkers for many types of cancers (Halazun et al, 2008;Smith et al, 2009;Asher et al, 2011;Raungkaewmanee et al, 2012;Allensworth et al, 2013;Ertas et al, 2013;Liu et al, 2013;Njolstad et al, 2013;Rassouli et al, 2013;Unal et al, 2013;Wang et al, 2013) CBC is an easy, inexpensive, routine preoperative investigation, so no extra cost would be incurred for its use. The preoperative platelet to lymphocyte ratio (PLR)-a novel and valuable platelet index-is known to be associated with survival outcomes of various cancers including gynecologic ones (Smith, et al, 2009;Asher et al, 2011;Raungkaewmanee, et al, 2012;Ertas, et al, 2013;Liu, et al, 2013;Rassouli, et al, 2013;Unal, et al, 2013;.…”
