Preoperative thrombocytosis has been shown to be a marker of advanced disease and poor survival in gynecologic malignancies, specifically endometrial, ovarian, and cervical cancers. The aim of this study is to provide a focused mini-review on all the existing literature concerning the role of preoperative thrombocytosis as a prognostic factor in vulvar squamous cell cancer (SCC). A PubMed search (until February 20, 2018) of all peer-reviewed and English-published articles was conducted using the following keywords: platelet, thrombocytosis, and vulvar cancer. Only three studies met the search protocol. It is concluded that preoperative thrombocytosis does not emerge as a substantial independent prognostic factor of disease-free survival (DFS) and overall survival (OS) in patients with vulvar SCC. Nevertheless, the interpretation of this conclusion should be done with extreme cautiousness. This can be ascribed to the heterogeneity of the reported data across the three studies, especially concerns pertaining to methodological designs. Additional related uniform studies are needed, so that data can be usefully pooled into a well-characterized systematic review/meta-analysis study, in order to devise valid mathematically proven conclusions. For now, International Federation of Gynecology and Obstetrics/ Fédération Internationale de Gynécologie et d'Obstétrique staging (FIGO staging) and inguino-femoral lymph node involvement continue to be the most established independent prognostic factors of DFS and OS in patients with vulvar SCC.

Activated platelets promote tumor cell growth, angiogenesis, and invasion. Platelet activity can be inferred by platelet volume indices (PVIs), which include platelet distribution width (PDW), mean pl...
As a hallmark of platelet activation, mean platelet volume (MPV) has been identified to be associated with various malignancies. However, the correlation between MPV, mean platelet volume/platelet cou...
BACKGROUND The aim of this study was to evaluate the predictive and prognostic value of the preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in pancreatic neuro...
Platelets interact with tumor cells and promote metastasis. The importance of platelets in post-transplant hepatocellular carcinoma (HCC) recurrence is unclear. Thus, we aimed to evaluate the associat...
We evaluated the prognostic potential of the combination of platelet count and neutrophil to lymphocyte ratio (COP-NLR) in patients with advanced head and neck cancer.
Thrombocytopenia is diagnosed when platelet count is lower than 150,000 U/L, it is a common hemostatic problem in neonatal intensive care units According to platelets count, it is classifi...
This randomized phase II trial studies how well cyclophosphamide and IRX-2 work in treating women with cervical squamous intraepithelial neoplasia 3 or squamous vulvar intraepithelial neop...
15 patients with biopsy proven active vulvar lichen sclerosus will be recruited by a clinic specializing in vulvar disorders. This study consists of a 2 week screening period and a 12-week...
Thrombocytopenia (platelet count < 100,000/mL) occurs in approximately 15% of women with preeclampsia. Neuraxial analgesia is contraindicated in parturients with a coagulopathy; therefore,...
The purpose of this study is to identify how the platelet count, complement system and endothelial markers are affected over time, after platelet transfusion in 4 different hematological p...
Disorders caused by abnormalities in platelet count or function.
A phospholipid from the platelet membrane that contributes to the blood clotting cascade by forming a phospholipid-protein complex (THROMBOPLASTIN) which serves as a cofactor with FACTOR VIIA to activate FACTOR X in the extrinsic pathway of BLOOD COAGULATION.
Specific receptors on cell membranes that react with PLATELET-DERIVED GROWTH FACTOR, its analogs, or antagonists. The alpha PDGF receptor (RECEPTOR, PLATELET-DERIVED GROWTH FACTOR ALPHA) and the beta PDGF receptor (RECEPTOR, PLATELET-DERIVED GROWTH FACTOR BETA) are the two principle types of PDGF receptors. Activation of the protein-tyrosine kinase activity of the receptors occurs by ligand-induced dimerization or heterodimerization of PDGF receptor types.
Storage-stable blood coagulation factor acting in the intrinsic pathway. Its activated form, IXa, forms a complex with factor VIII and calcium on platelet factor 3 to activate factor X to Xa. Deficiency of factor IX results in HEMOPHILIA B (Christmas Disease).
