Abstract
Background Venous thromboembolism (VTE) is a quite common complication in acute leukemia, although its real incidence is unknown. The best treatment of this complication is still a matter of debate due to the very high risk of hemorrhage in this group of patients. Patients and methods From December 2000 to December 2002 four Caucasian patients with acute leukemia developed VTE complications. The patients were three men and one woman, mean age 55.7 years (range, 27-77). Two patients with acute lymphoid leukemia (L1 and L2 according to the FAB classification) developed deep venous thrombosis during the administration of chemotherapy; one patient with acute myeloid leukemia (AML, M2 according to the FAB classification) had pulmonary thromboembolism at diagnosis, while another AML patient (M4 according to FAB) showed deep venous thrombosis as the first symptom of leukemia. The clinical diagnosis of symptomatic VTE was confirmed by objective imaging procedures including lower limb venous color Doppler imaging in all cases and a ventilation-perfusion lung scan in one case. All patients were treated with enoxaparin 100 IU/kg subcutaneously twice daily for one month, followed by 150 IU/kg once daily for at least five months. When the platelet count was below 20,000 × 109/L, the dose was reduced by 50%. Results During antithrombotic treatment neither VTE recurrences nor hemorrhagic complications or heparin-induced thrombocytopenia occurred. The platelet count at the beginning of enoxaparin treatment was very low (mean, 55,750 × 109/L; range, 12,000-121,000 × 109/L) and treatment did not affect platelet recovery. Conclusions Enoxaparin proved to be efficacious and safe in the management of deep venous thrombosis with or without pulmonary embolism in patients affected by acute leukemia. Enoxaparin cured acute venous thrombosis, prevented recurrences and did not cause any hemorrhagic complications despite prolonged severe thrombocytopenia.

Abstract
OBJECTIVE To compare quality of life (QOL) of patients following iatrogenic bile duct injuries (BDI) to matched controls. SUMMARY BACKGROUND DATA BDI complicate approximately 0.3% of all cholecystectomy procedures. The literature regarding impact on quality of life is conflicted as assessment using clinical determinants alone is insufficient. METHODS The medical outcomes study short form 36 (SF-36), a sensitive tool for quantification of life quality outcome, was used. The study group of iatrogenic BDI was compared with an age- and sex-matched group who underwent uncomplicated cholecystectomy. Telephone questionnaire using the SF-36 quality of life tool was administered to both groups at a median postoperative time of 12 years 8 months (range, 2 months -20 years). RESULTS Seventy-eight patients were referred with BDI but due to mortality (n = 10) and unavailability (n = 6) 62 participated. The age- and sex-matched control cohort had undergone uncomplicated cholecystectomy (n = 62). Comparison between groups revealed that 7 of 8 variables examined were statistically similar to those of the control group (physical functioning, role physical, bodily pain, general health perceptions, vitality and social functioning, and mental health index). Mean role emotional scores were slightly worse in the BDI group (46 vs. 50) but the significance was borderline (P = 0.045). Subgroup analysis by method of intervention for BDI did not demonstrate significant differences. CONCLUSION Quality of life of surviving patients following BDI compares favorably to that after uncomplicated laparoscopic cholecystectomy.

Abstract
Although oral vitamin K antagonists such as warfarin have been the mainstay of thromboprophylaxis in the outpatient setting, warfarin has potential disadvantages, including food and drug interactions, the need for drug monitoring, intolerance, failure, and hypersensitivity syndromes. The use of low-molecular-weight heparin as a primary or secondary thromboprophylactic drug in the outpatient setting for extended prophylaxis or as outpatient bridging therapy has been addressed less extensively. Available evidence shows that low-molecular-weight heparin can be used as extended outpatient-based primary thromboprophylaxis for major orthopedic and cancer surgery and is a safe and effective alternative to warfarin in long-term secondary thromboprophylaxis, especially in cancer patients and in pregnant women. Low-molecular-weight heparin can also be used as an alternative to unfractionated heparin as outpatient-based bridging therapy. In addition to good clinical outcomes and financial benefits, mainly resulting from a reduction in the length of hospital stay, the use of extended-duration low-molecular-weight heparin in the outpatient setting appears to be feasible, with high patient compliance.

Abstract
PURPOSE To develop guideline recommendations for the use of anticoagulation in the prevention and treatment of venous thromboembolism (VTE) in patients with cancer. METHODS A comprehensive systematic review of the medical literature on the prevention and treatment of VTE in cancer patients was conducted and reviewed by a panel of content and methodology experts. Following discussion of the results, the panel drafted recommendations for the use of anticoagulation in patients with malignant disease. RESULTS The results of randomized controlled trials of primary and secondary VTE medical prophylaxis, surgical prophylaxis, VTE treatment, and the impact of anticoagulation on survival of patients with cancer were reviewed. Recommendations were developed on the prevention of VTE in hospitalized, ambulatory, and surgical cancer patients as well as patients with established VTE, and for use of anticoagulants in cancer patients without VTE to improve survival. CONCLUSION Recommendations of the American Society of Clinical Oncology VTE Guideline Panel include (1) all hospitalized cancer patients should be considered for VTE prophylaxis with anticoagulants in the absence of bleeding or other contraindications; (2) routine prophylaxis of ambulatory cancer patients with anticoagulation is not recommended, with the exception of patients receiving thalidomide or lenalidomide; (3) patients undergoing major surgery for malignant disease should be considered for pharmacologic thromboprophylaxis; (4) low molecular weight heparin represents the preferred agent for both the initial and continuing treatment of cancer patients with established VTE; and (5) the impact of anticoagulants on cancer patient survival requires additional study and cannot be recommended at present.

Abstract
PURPOSE A substantial clinical need exists for an alternative to vitamin K antagonists for treating deep-vein thrombosis in cancer patients who are at high risk of both recurrent venous thromboembolism and bleeding. Low-molecular-weight heparin, body-weight adjusted, avoids anticoagulant monitoring and has been shown to be more effective than vitamin-K-antagonist therapy. SUBJECTS AND METHODS Subjects were patients with cancer and acute symptomatic proximal-vein thrombosis. We performed a multi-centre randomized, open-label clinical trial using objective outcome measures comparing long-term therapeutic tinzaparin subcutaneously once daily with usual-care long-term vitamin-K-antagonist therapy for 3 months. Outcomes were assessed at 3 and 12 months. RESULTS Of 200 patients, 100 received tinzaparin and 100 received usual care. At 12 months, the usual-care group had an excess of recurrent venous thromboembolism; 16 of 100 (16%) versus 7 of 100 (7%) receiving low-molecular-weight heparin (P=.044; risk ratio=.44; absolute difference -9.0; 95% confidence interval [CI], -21.7 to -0.7). Bleeding, largely minor, occurred in 27 patients (27%) receiving tinzaparin and 24 patients (24%) receiving usual care (absolute difference -3.0; 95% CI, -9.1 to 15.1). In patients without additional risk factors for bleeding at the time of randomization, major bleeding occurred in 0 of 51 patients (0%) receiving tinzaparin and 1 of 48 patients (2.1%) receiving usual care. Mortality at 1 year was high, reflecting the severity of the cancers; 47% in each group died. CONCLUSION Our findings confirm the limited but benchmark data in the literature that long-term low-molecular-weight heparin is more effective than vitamin-K-antagonist therapy for preventing recurrent venous thromboembolism in patients with cancer and proximal venous thrombosis.

Abstract
The association between neoplastic diseases and venous thromboembolism (VTE) is known since long time ago. The nature of this association is bidirectional. On one hand, cancer increases the incidence of venous thrombosis and, on the other hand, the hemostatic system does play a key role in the tumorigenesis process. However, despite recent advances in the field, prophylaxis and treatment of VTE in cancer patients is still a challenge, due to the complexity of this type of patients. This review is focused on some important points regarding management of VTE in cancer patients such as physiopathology, epidemiology, search for hidden malignancy, prognostic impact, prophylaxis in the medical and surgical setting, or initial and long-term treatment.

Abstract
Venous thromboembolism (VTE) constitutes an important health problem in developed countries. Owing to their underlying malignancies, people with cancer are at particularly high risk of VTE. The level of this risk is influenced by several factors, including type of cancer and the presence or absence of metastases. However, different types of oncology treatment can also further increase the thrombotic risk. Consequently, primary and secondary thromboprophylaxis in people with cancer should be considered as part of any integrated oncology treatment. Moreover, recent exciting studies have suggested that low molecular weight heparins (LMWH) may also influence overall survival in people with cancer. Clearly, these findings raise the likelihood that the use of LMWH in oncology practice may increase significantly in the near future. However, it is important to appreciate that the use of thromboprophylaxis in people with cancer is complicated by a number of specific problems. In this overview, we have systematically addressed the difficult clinical issues that are involved in the selection of appropriate primary and secondary thromboprophylaxis for people with cancer.

Abstract
Treatment of venous thromboembolism includes an acute phase treatment, followed by a secondary prophylaxis period. Oral anticoagulants have been the usual treatment for secondary prophylaxis of VTE. However, some issues regarding oral anticoagulant treatment (OAT), such as length or intensity are controversial. The appropriate duration of OAT depends on the individual risk of both, thrombotic recurrence and hemorrhagic complications. Recent studies suggest that full-dose OAT is more effective and as safe as low-dose OAT. On the other hand, low-molecular-weight heparins are an alternative for the secondary prophylaxis of VTE, being the treatment of choice in patients with cancer or during pregnancy. Probably, new antithrombotic drugs such as idraparinux or ximelagatran, will be considered as another therapeutic alternative in a near future.

Abstract
Low-molecular-weight heparins (LMWHs) are used widely in the treatment and prevention of venous thromboembolism (VTE). The LMWHs dalteparin and enoxaparin reduce the rate of VTE by at least 50% if administered for 4-5 weeks following major orthopedic surgery, compared with in-hospital prophylaxis for 7-15 days. Meta-analyses have confirmed that the size of the reduction is similar for both clinical and asymptomatic VTE. Vitamin K antagonists (VKAs) have been shown to be associated with significantly higher bleeding rates compared with LMWH when used as prolonged prophylaxis against VTE following major orthopedic surgery. Patients with cancer are a recognized group at high risk of VTE, and those undergoing major surgery for their malignancy are at particular risk. Evidence from clinical trials is amassing to show that prolonged prophylaxis with LMWH (dalteparin, enoxaparin) in these patients can significantly reduce the rate of postoperative VTE. In cancer patients with acute VTE, the traditional approach is to initiate acute treatment with unfractionated heparin or LMWH followed by long-term treatment with VKA to prevent recurrence. However, clinical trial data have confirmed that the LMWH dalteparin, when administered for 6 months, is significantly more effective than VKA in preventing recurrence, cutting the rate of VTE by 52% without increasing the risk of bleeding. A new and intriguing area of interest is whether LMWH can enhance survival in patients with cancer. Preliminary data suggest that a biological effect of LMWH may act to prolong survival in patients with cancer.
