  • Title
    • A risk model for prediction of venous thromboembolism in gynaecological cancer patients post surgery
  • Summary
    • Venous thromboembolism (VTE) is a common cause of death in patients with solid tumours. Cancer itself causes a hypercoagulable state, in addition chemotherapy and surgery enhance the risk. Gynaecological cancers have been associated with high rates of VTE which is excacerbated by pelvic surgery and chemotherapy. A recent study in our centre showed that one third of VTE in ovarian cancer patients occurs within 5 days of surgery despite heparin prophylaxis. Recently, clinical risk models have been developed to predict VTE in patients undergoing chemotherapy, these models have been shown to be more powerful when combined with haemostatic biomarkers. Thrombus formation is complex in cancer and is thought to result from a release of procoagulant material from the tumour combined with damage to the endothelium as a result of chemotherapy and surgery. Global tests of hypercoagulability which capture these effects are therefore attractive as determinants of thrombotic risk. Calibrated automated thrombograpy (CAT) is a recently developed global test which measures thrombin generation in plasma. Increased thrombin generation is predictive of VTE in a variety of clinical settings. The overarching aim of this project is to develop and validate a specific risk scoring model for VTE risk in gynaecological cancer patients using a combination of easily available clinical and laboratory parameters and haemostatic biomarkers. In a large population of gynaecological cancer patients, we will identify the key risk factors for VTE and use them to derive a risk score model. Based on our pilot data, we believe that a thrombin generation test may be a useful biomarker for VTE in gynaecological cancer. By understanding the mechanisms by which gynaecological cancer increases procoagulant activity, we will optimise a specific thrombin generation assay which when combined with the derived risk score model will accurately identify gynaecological cancer patients at high risk of VTE.

  • Summary
    • A recent survey of patients who suffered a thrombosis during their cancer journey showed that, generally, patients are not warned about the risk of clots during cancer and are not told what to look out for. In addition research by our group has shown that only 45% of gynaecologists in Europe are using the correct guidelines for thrombosis prevention. The aim of this project is to increase awareness among patients regarding thrombosis and to provide an opportunity for knowledge exchange between gynaecologist and scientists working in the area

  • Summary
    • The metabolic syndrome is characterised by low-level inflammation, coagulation activation and increased risk of cancer. This study seeks to interrogate the inter-linked nature of these mechanisms in ovarian cancer. The association while present in ovarian cancer patients is not well defined. The aim of this study is to assess if platelet cloaking of CTCs in obese patients with ovarian cancer, due to increased systemic inflammation is a mechanism underlying worse prognosis in these patients.

    • THE ROLE OF TISSUE FACTOR IN THE TRANSITION FROM ENDOMETRIOSIS TO CLEAR CELL CANCER OF THE OVARY
  • Summary
    • Increased expression of both PAR-2 and TF in the eutopic and ectopic endometrium from women with endometriosis compared with normal women has been reported (Krikun et al,2008) however it is unknown whether a further increase in expression is implicated in malignant transformation of endometrioma into clear cell cancer. Our hypothesis is that expression and activation of the TF-VIIa-PAR-2 signalling pathway is further increased in clear cell cancers particularly those formed on a background of endometriosis and that this may provide a potential target for treatment of clear cell cancers. We also believe that TFPI-2 may be a useful diagnostic marker for clear cell cancers. The aim of the study is to compare the expression of TF, VIIa and PAR-2 in clear cell cancers with endometrial tissue from patients with endometriosis. A secondary aim is to investigate the role of serum TFPI-2 as a possible non invasive tool for distinguishing endometriosis from clear cell cancers.

    • Thromboelastography as a predictor of venous thrombosis in gynaecological oncology patients undergoing surgery.
  • Summary
    • Ovarian cancer is associated with high rates of venous thromboembolism (VTE) particularly after surgery even in the setting of appropriate prophylaxis.The treatment and prevention of VTE is challenging in these patients after major surgery, as pelvic surgery itself is also an additional high risk factor for VTE. Thromboelastography(TEG) is a technique which allows rapid global assessment of haemostatic/fibrinolytic function and has been proposed as a marker of hypercoagulability in a variety of clinical settings. The aim of this study is to determine the level of hypercoagulability using TEG in patients undergoing major gynaecological surgery for suspected cancer, and to determine the potential of TEG as a predictor of VTE.

  • Summary
    • Increased Tissue Factor from tumour cells may cause an enhanced plasma procoagulant activity ultimately resulting in VTE. The majority of these patient would have major pelvic surgery as part of their treatment, with the risk of bleeding. Endogenous Thrombin Potential (ETP) assay is a new method which has shown potential as predictor of VTE risk. The aim of the study is to compare the procoagulant activity in plasma of patients with benign and malignant ovarian tumous using the ETP assay. and to compare the procoagulant activity levels in patients following neoadjuvant chemotherapy with those undergoing surgery for primary tumours

    • Prediction and Prevention of venous thromboembolism in pregnancy
  • Summary
    • Venous thromboembolism remains the leading cause of maternal morbidity and mortality. Delayed diagnosis, inadequate treatment and inadequate thromboprophylaxis account for the majority of deaths associated with this disease. Pharmacokinetics studies are required in specific groups of pregnant women receiving LMWH prophylaxis in order to devise effective evidence based dosing strategies. The recent triennial report indentified obese pregnant women and women post caesarean section, as two groups particularly at risk and where further work is required. This study will (1) investigate thrombin activity as a potential predictive tool for venous thromboembolism in pregnancy using the SCOPE study cohort (2) study the full anticoagulant (anti-IIa and anti-Xa) profile of obese pregnant woman and women post caesarean section receiving LMWH prophylaxis.

    • THE ROLE OF TISSUE FACTOR AND TISSUE FACTOR PATHWAY INHIBITOR IN OVARIAN CANCER
  • Summary
    • Tissue Factor (TF) is a potent trigger of the coagulation cascade which is normally released following vascular injury. In normal tissue, TF expression is restricted to extravascular sites however recent evidence has shown that tumour cells can constitutively express TF leading to thrombin and fibrin formation on the cell surface. This activation of the coagulation system has been shown to be related to survival and is also implicated in the increased venous thromboembolic (VTE) risk in cancer patients. Tissue factor pathway inhibitor (TFPI) is the natural inhibitor of TF coagulant and signalling activities. TFPI exhibits anti-angiogenic and antimetastatic effects in vitro and in vivo. In animal models of experimental metastasis, both circulating and tumour associated TFPI have been shown to significantly reduce tumour cell induced activation and lung metastasis. Ovarian cancer is the leading cause of death from gynaecological malignancy. The lifetime risk of developing the disease is now estimated at 1 in 59. Ovarian cancer is known to display a particular association with VTE with reports of up to 14% of patients with clear cell carcinoma of the ovary developing thromboembolic complications. In addition, patients undergoing chemotherapy have an enhanced risk of vascular thrombosis which varies among different chemotherapeutic regimens. VTE is a life threatening condition and its management is challenging in these patients who often undergo major pelvic and abdominal surgery and receive combination chemotherapy. The pathological and cellular mechanisms underlying this thrombogenic risk in cancers are not fully understood. The aim of this study is to determine the role of TF and its inhibitor TFPI in the progression of ovarian cancer and to assess their potential as predictive tools for venous thrombosis in ovarian cancer patients during treatment.

  • Summary
    • HRT is known to cause changes in coagulation and fibrinolytic gene activation which may explain the increased risk of thrombosis associated with these combinations. If these preparations are taken transdermally, the liver first pass effect is avoided and this may reduce their effects on coagulation and fibrinolytic activity. The aim of this study is to investigate the role of the route of admiminstration on the effects of HRT on haemostasis. Levels of coagulation and fibrinolytic activators and inhibitors will be measured in a group of healthy post menopausal women taking a transdermal preparation compared with a group taking an oral preparation
