ObjectiveTo determine whether preoperative platelets to lymphocyte ratio (PLR) could predict disease stage, surgical outcome, and survival in patients with epithelial ovarian cancer (EOC).MethodsMedical records of EOC patients who had surgery between January 2004 and December 2010 were reviewed. Clinicopathological and complete blood count data were collected. The optimal predictive value of PLR to predict advanced stage, suboptimal surgery, and survival was determined and compared with those of thrombocytosis (≥400,000 cells/mm3) and neutrophil to lymphocyte ratio (NLR) ≥2.6.ResultsA total of 166 EOC patients were included in the study. PLR of 200 yielded better predictive values than those of thrombocytosis and NLR ≥2.6. The area under curve (AUC), sensitivity, specificity, positive and negative predictive values, and accuracy of PLR to predict advanced stage were: 0.66, 59.0%, 72.7%, 65.7%, 66.7%, and 66.3%, respectively. The corresponding values to predict suboptimal surgery were: 0.70, 70.0%, 69.8%, 50.0%, 84.4%, and 69.9%. The patients who had PLR≥200 had significantly shorter progression-free and overall survivals than those with PLR<200. Stage, grade, surgical outcome, thrombocytosis, and PLR were significant prognostic factors for survivals by univariable analyses while only stage remained significant by multivariable analysis.ConclusionPLR had potential clinical value in predicting advanced stage disease or suboptimal surgery. PLR was a better prognostic indicator for survivals of EOC patients compared to thrombocytosis or NLR>2.6.
Contentsport was located left at 8 cm from umbilicus, second port was 20 mm sized at umbilicus, third port was located right at 8 cm from umbilicus, and fourth was located right at 8 cm from the third port (near the right flank). Uterus was tied with needle-straightened multifilament Vicryl 2-0 and tagged uterus was manipulated by fourth arm of the robot. If additional traction is required, instrument was inserted though the umbilical trocar site. During operation, the tagged uterus was successfully manipulated and appropriate parametrial space was exposed. Pathologically, all surgical margins were not involved with cancer. No tumor cells were seen in cytologic exam before and after the colpotomy. Robotic radical hysterectomy can be easily and safely done with the traction of tagged uterine suture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
