Frequency of Arterial Thromboemobolic Events in Patients with Cancer Associated Venous Thromboembolism

Background:Patients with cancer are at high risk of both venous thromboembolism (VTE) and arterial events, however, little is known about the association between venous and arterial thromboembolic events in patients with cancer. In this study, we evaluated the incidence and relative risk of subsequent arterial thromboembolism in patients with a confirmed diagnosis of acute cancer-associated VTE. Methods:We conducted a retrospective cohort study at the Cleveland Clinic Taussig Cancer Institute of cancer patients with confirmed VTE who were referred to a centralized thrombosis clinic between January 2017-October 2019 with at least 6 months of follow-up. Arterial thrombotic events (ATE), including myocardial infarction, peripheral arterial thrombosis, and ischemic stroke, were identified by manual review of electronic medical records. The cumulative incidence rate of each ATE event was calculated. Results:The study population comprised 294 patients with a median age of (63.5) years (range 27-90), and 49.7 % were male. The cumulative incidence rate of overall ATE during the 6-month, 1-year, and 2-year follow-up period was 3.07%, 3.42%, and 3.42%, respectively. A total of 10 patients who experienced arterial events of whom 7 had ischemic stroke, 2 had myocardial infarction, 2 had peripheral arterial thrombosis where one patient had two arterial events of myocardial infarction and peripheral arterial thrombosis(Table 1 shows the incidence rates of arterial events). Amongst patients with ATE, 30 % were active smokers (n=3), 90% had hypertension (n=9), 20% had diabetes mellitus (n=2), 50% had a family history of coronary artery disease (n=5), 40% were on statin and daily aspirin use (n=4), 40% were obese with BMI >30 (n=4). 40% of ATE patients(n=4) were on a therapeutic anticoagulant therapy at the time of arterial thrombotic event (3 on enoxaparin, 1 on apixaban) Conclusion:Cancer patients with acute VTE have a substantial increased risk of subsequent arterial thromboembolism particularly in the first six months after VTE. Ischemic stroke was the most frequent arterial event and ATE events occured despite therapeutic anticoagulation in a large subset of our cohort. Further prospective studies are needed to better understand the risk of ATE in cancer patients, and further studies should be designed to mitigate the risk of arterial events in this patient population.

Abstract Introduction Cancer and its treatments are well-recognized risk factors for the development of venous thromboembolism (VTE). The occurrence of VTE has been associated with an increased mortality in patients with cancer. Here we retrospectively reviewed the incidence and characteristics of cancer-associated thrombosis (CAT) in a large cohort of cancer patients treated at our institution as well as compared treatment outcomes of this group of patients with a 1:1 matched pair group of cancer patients without CAT. Methods Data of consecutive patients, 18 years of age or older, with a newly diagnosis of both hematologic malignancies or solid tumors who diagnosed and treated either as an inpatient or outpatient setting at our institution between 2011 to 2015 were included in this analysis. Patients who received anticoagulants for the purpose of either prophylaxis or treatment within 2 weeks before cancer diagnosis and who did not have a histologically confirmed a cancer diagnosis or complete follow up data were excluded from the study. To compare the outcomes of cancer patients with and without CAT, cancer patients who did not experience CAT were randomly selected from the same database and were matched individually (1:1) to cancer patients with CAT based on age, sex, cancer type and stage (limited or advanced) to form a matched cohort of patients as control. Primary outcome was cumulative incidence of CAT at 6 months and 1 year after cancer diagnosis, while incidence of recurrent VTE, major and minor bleeding, relapse, non-relapse mortality (NRM), overall survival (OS) and progression-free survival (PFS) were analyzed as secondary outcomes. CAT was defined as at least 1 site of venous thrombosis confirmed by imaging results, which occurred anytime after the initial diagnosis, during the treatment or follow-up. Results Total 2,291 newly diagnosed cancer patients (633 patients with hematologic malignancies and 1,658 patients with solid cancers) with a median age of 58 years (range 18-93 years) were included in the analysis. CAT was developed in 83 patients (52 females and 31 males) with a median age of 61 year (range 20-85 years). The cumulative incidence of CAT at 6 months and 1 year was 2.7% and 3.4%, respectively. The median time from cancer diagnosis to the diagnosis of CAT was 3.2 months (range 1- 62 months). Sites of VTE were deep vein thrombosis in extremities (N=46; 55.4%), pulmonary embolism (N=6; 7.2%), splanchnic vein thrombosis (N=9; 10.8%) and cerebral venous sinus thrombosis (N=5, 6%). Seventeen patients (20%) developed more than 1 site of VTE. Sixty-nine (83%) cases with CAT were diagnosed in patients with hematologic malignancies including 35, 22 and 12 cases with lymphoma, acute leukemia and myeloproliferative neoplasms, respectively. Overall the incidence was 10.9% in hematologic malignancies and 0.8% in solid tumors. The majority of the CAT cases occurred in advanced stage cancers (66 patients; 79.5%) while 13 cases (15.7%) were diagnosed during ambulatory chemotherapy treatment. None of the patients with CAT received prophylaxis anticoagulant during cancer treatment or follow up period. Characteristics of patients with CAT are summarized in Table 1. Of 83 patients with CAT, 66 patients were treated with anticoagulants, while inferior vena cava filter was used in 8 patients (9.6%). The cumulative incidence of total bleeding events at 1 year was 21.1% whereas cumulative incidence of major bleeding was 6.8%. The cumulative incidence of recurrent thrombosis at 1 year was 8.3%. Cancer patients who developed CAT had both a significantly higher NRM (26.2% vs. 13% at 1 year, p=0.004) (Figure 1A) and relapse rate (63.3% vs. 43.5% at 5 years, p=0.002) (Figure 1B) when compared with control group, which resulted in a significantly lower 5-year OS (24.9% vs. 62.7%; p<0.0001) (Figure 1C) and PFS (16.9% vs. 46%; p<0.0001) (Figure 1D). Advanced stage cancer and development of CAT were associated with poor OS in a multivariable analysis with HR of 6.9 (95%CI 2.7-17.7) and 3.9 (95%CI 2.2-7.0), respectively. Both factors also independently predicted risk of relapse with HR of 4.6 (95%CI 1.8-11.6, p=0.001) and 3.4 (95%CI 1.7-6.8, p<0.0001), respectively. Conclusions Development of CAT is associated with an increased NRM, relapse rate and poor survival in patients with cancer. Effective strategies to prevent CAT especially in high-risk cancer patients are needed to help improve outcomes. Disclosures No relevant conflicts of interest to declare.

Cancer Associated Thrombosis

Background: The treatment paradigm for cancer associated thrombosis (CAT) has evolved over recent years from using low molecular weight heparin (LMWH) to direct oral anticoagulants (DOACs). Some randomized trials suggest decreased rates of recurrent venous thromboembolism (VTE) in CAT patients treated with DOACs compared to LMWH but also reported increased rates of bleeding. The Cleveland Clinic Taussig Cancer Center has been treating cancer thrombosis in a centralized CAT clinic since 2014. Here we report our rates of bleeding and recurrent VTE in cancer patients treated with anticoagulation. Methods: We prospectively followed cancer patients referred to our clinic from 8/2014-10/2019. A total of 1548 patients were referred to the clinic, of whom 462 were diagnosed with an acute VTE. VTE events, including deep venous thrombosis, pulmonary embolism, and visceral thrombosis, were noted. The comparison of bleeding rates (defined using ISTH criteria for major and clinically relevant non major bleeding, CRNMB) among treatment groups (LMWH vs DOACs) was examined using chi-square test. Rate of recurrent VTE was analyzed using a competing model in which death was treated as a competing risk. Results: The study population comprised 462 patients with acute VTE with a mean age of 62.67±12.23 and 51.8 % males. Of these, 234 (52.9%) received LMWH, 161(36.4%) received DOACs, and 47 (10.6%) received other agents including warfarin for initial anticoagulation. Overall, the 6-month, 1 year, and 2-year VTE recurrence rate was 5.9%, 6.6%, 7.9%, respectively. Recurrent VTE rates were similar for LMWHs, DOACs and other agents (P>0.05). Of 368 patients for whom follow-up data was available, 74 (16.7%) had bleeding event , of which 25 (33.8%) had major bleeding and 49 (66.4%) had CRNMB at 6 month follow-up with no difference across three treatment groups (p=0.56). Conclusion: In this real-world practice setting, rates of recurrent VTE and bleeding were similar for DOACs and LMWH suggesting that with careful patient selection the concern for higher bleeding with DOACs in cancer patients can be safely overcome.

Abstract Introduction: Patients with cancer are not only at a high risk for developing primary but also recurrent venous thromboembolism (VTE). These events lead to increased burden of cancer management and healthcare costs. It was estimated that all-cause health care costs for cancer patients with VTE were $30,538/patient higher than in those without VTE (Khorana, 2013). To our knowledge, very little information exists on cost of VTE recurrence among cancer patients. The objective of this study was to analyze resource utilization and costs of patients with cancer experiencing a VTE recurrence using a large claims database. Methods: Medical and pharmacy claims from the Humana Database between 1/1/2013 and 05/31/2015 were analyzed. Newly diagnosed cancer patients with a first VTE diagnosis occurring after their first cancer diagnosis and with ≥1 dispensing of an anticoagulant agent within 7 days after their VTE diagnosis, were selected. Baseline characteristics were evaluated during the 6 month period prior to the index VTE. VTE recurrences were defined as hospitalizations with a primary diagnosis of VTE. Patients were classified into two groups: patients who experienced a VTE recurrence and patients who did not. Resource utilization and costs were evaluated for the entire follow up period, starting with the initiation of the anticoagulant therapy until whichever was earlier, end of eligibility or end of data. Healthcare resource utilization evaluated included number of hospitalizations, hospitalization days, emergency room (ER) visits, and outpatient visits. All-cause and VTE-related healthcare resource utilization was evaluated. Comparisons between patients with a VTE recurrence and patients without a VTE recurrence were performed using rate ratios (RR) and statistical differences between groups as well as 95% confidence intervals [95% CI] were calculated using Poisson regression models. All-cause and VTE-related healthcare costs were evaluated in per-patient-per-year (PPPY) and compared using mean cost difference. Results: A total of 2,428 newly diagnosed cancer patients who developed VTE and were treated with anticoagulants were identified. Of these, 413 (17.1%) experienced recurrent VTE during the follow up period. Patients who developed recurrent VTE and those who did not were similar in terms of age, gender, race, and region. No statistically significant differences between groups were observed in Charlson comorbidity index or in selected comorbidities during the 6 month baseline period. However, more patients with recurrent VTE recurrence had their index VTE documented during a hospitalization (61.3% vs. 55.4%, p=0.03). Patients with a VTE recurrence had significantly more ER and outpatient visits at baseline compared to those without recurrence, but no statistically significant difference was observed in baseline total healthcare costs ($29,352 vs. $27,955, p=0.44, respectively). The mean follow-up was similar between groups: 9.6 months for patients experiencing a VTE recurrence and 9.3 months for patients without a VTE recurrence (p=0.4059). Patients with a VTE recurrence had higher all-cause resource utilization rates (RRs; 95% CI) compared to patients without a VTE recurrence (hospitalization [2.37; 2.23 - 2.52], hospitalization days [2.64; 2.57 - 2.72], ER visits [1.62; 1.48 - 1.76], and outpatient visits [1.26; 1.24 - 1.28]). The rates of VTE-related hospitalization and VTE-related hospitalization days were close to $30,000 higher in patients with a VTE recurrence (Figure 1). The all-cause healthcare costs were $84,708 PPPY in patients with a VTE recurrence compared to $44,903 in patients without a VTE recurrence. The difference was mainly explained by lower VTE-related hospitalization costs (Figure 2). Conclusion: This real-world claims analysis showed that cancer patients with recurrent VTE consume significantly more healthcare resources. Total healthcare costs were nearly 2-fold higher in cohort with than in cohort without VTE recurrence. Close to 75% of the total cost difference was associated with VTE recurrence. VTE-related costs were ~4-fold higher in cohort with than in cohort without VTE recurrence. Reducing VTE recurrence in patients with cancer could lead to substantial healthcare cost savings.

Recurrent Venous Thromboembolism

A small proportion of patients with deep vein thrombosis develop recurrent venous thromboembolic complications or bleeding during anticoagulant treatment. These complications may occur more frequently if these patients have concomitant cancer. This prospective follow-up study sought to determine whether in thrombosis patients those with cancer have a higher risk for recurrent venous thromboembolism or bleeding during anticoagulant treatment than those without cancer. Of the 842 included patients, 181 had known cancer at entry. The 12-month cumulative incidence of recurrent thromboembolism in cancer patients was 20.7% (95% CI, 15.6%-25.8%) versus 6.8% (95% CI, 3.9%- 9.7%) in patients without cancer, for a hazard ratio of 3.2 (95% CI, 1.9-5.4) The 12-month cumulative incidence of major bleeding was 12.4% (95% CI, 6.5%-18.2%) in patients with cancer and 4.9% (95% CI, 2.5%-7.4%) in patients without cancer, for a hazard ratio of 2.2 (95% CI, 1.2-4.1). Recurrence and bleeding were both related to cancer severity and occurred predominantly during the first month of anticoagulant therapy but could not be explained by sub- or overanticoagulation. Cancer patients with venous thrombosis are more likely to develop recurrent thromboembolic complications and major bleeding during anticoagulant treatment than those without malignancy. These risks correlate with the extent of cancer. Possibilities for improvement using the current paradigms of anticoagulation seem limited and new treatment strategies should be developed.

SummaryVenous thromboembolism (VTE) is a frequent complication of malignancy. The aim of this study was to investigate whether multi-state modelling may be a useful quantitative approach to dissect the complex epidemiological relationship between hypercoagulability, VTE, and death in cancer patients. We implemented a three-state/three-transition unidirectional illness-death model of cancer-associated VTE in data of 1,685 cancer patients included in a prospective cohort study, the Vienna Cancer and Thrombosis Study (CATS). During the two-year follow-up period, 145 (8.6%) patients developed VTE, 79 (54.5%) died after developing VTE, and 647 (38.4%) died without developing VTE, respectively. VTE events during follow-up were associated with a three-fold increase in the risk of death (Transition Hazard ratio (HR)=2.98, 95% confidence interval [CI]: 2.36-3.77, p< 0.001). This observation was independent of cancer stage. VTE events that occurred later during follow-up exerted a stronger impact on the risk of death than VTE events that occurred at earlier time points (HR for VTE occurrence one year after baseline vs at baseline=2.30, 95% CI: 1.28-4.15, p=0.005). Elevated baseline D-dimer levels emerged as a VTE-independent risk factor for mortality (HR=1.07, 95% CI: 1.05-1.08, p< 0.001), and also predicted mortality risk in patients who developed VTE. A higher Khorana Score predicted both the risk for VTE and death, but did not predict mortality after cancer-associated VTE. In conclusion, multi-state modeling represents a very potent approach to time-to-VTE cohort data in the cancer population, and should be used for both observational and interventional studies on cancer-associated VTE.

Introduction Venous thromboembolism (VTE) is a difficult to treat condition in patients with cancer with a persisting risk of recurrent VTE during anticoagulant treatment with low-molecular weight heparin (LMWH). Recent data suggest that direct oral anticoagulants (DOACS) are associated with a lower risk of recurrence but a higher risk of bleeding in these patients. Predicting the risk of recurrent VTE with LMWH may help to select the best treatment option. We conducted a prospective multicenter observational cohort study in cancer patients with VTE treated with tinzaparin for 6 months in order to validate the Ottawa score (NCT03099031) and search for additional risk of recurrent VTE. The Ottawa score is composed of 5 variables, female sex (+1), lung cancer (+1), breast cancer (-1) cancer stage 1 (-2) and previous DVT (+1). A score ≤0 is associated with a low risk of recurrent VTE. Methods Adult cancer patients with recent diagnosis of documented symptomatic or incidental VTE (deep vein thrombosis (DVT) or pulmonary embolism (PE) treated with tinzaparin for 6 months were included in the study. The primary endpoint was the recurrence of symptomatic or asymptomatic VTE within the first 6 months of treatment with tinzaparin. Other endpoints were symptomatic recurrent VTE, major bleeding, heparin induced thrombocytopenia (HIT), all-cause mortality within 3 and 6 months. All events were adjudicated by a Central Adjudication Committee. Time-to-event outcomes were estimated by the Kalbfleisch and Prentice method to take into account the competing risk of death. Cumulative incidences were presented with corresponding 95% confidence interval (95% CI). To validate the Ottawa score, the area under the curve (AUC) and its 95% CI were calculated on receiver operating characteristic (ROC) curve analysis; the most discriminant cut-off was then determined by calculating the Youden index. Univariate and multivariate analyses were performed to identify additional predictive factors of recurrent VTE to those included in the Ottawa score using the Fine and Gray method and adjusted on factors included in the Ottawa score. Hazard ratio and their 95% CI were calculated. Results A total of 409 patients were included and analyzed on an intention-to-treat basis; the median age was 68 years and 51% of patients were males. 60.4% of patients had a PE (with or without DVT) .64% received chemotherapy at inclusion or in the month before inclusion. Lung (31.3%) and digestive track (18.3%) cancers were the most common cancer types and 67.0% had stage IV cancers. According to Ottawa score, 58% of patients were classified at high clinical probability of recurrence (score ≥ 1). During the 6 months treatment period, 23 patients had a recurrent VTE, yielding a cumulative incidence of 6.1% (95% CI 4.0-9.3) with a median time for recurrent VTE of 33 days. The recurrence rate of VTE was estimated to 7.8% (95% CI 4.9-12.5) for patients classified at high risk of recurrence according to the Ottawa score (score ≥ 1) compared to 3.8% (95%CI 1.6-8.9) for other patients (Ottawa score < 1). AUC of the Ottawa score was 0.60 (95% CI 0.55-0.65). In multivariable analysis, none of the potential risk factors for recurrent VTE was significantly associated with recurrent VTE at 6 months. During the 6 months treatment period, 15 patients had a major bleeding and 2 patients experienced a HIT. At 3 and 6 months, 104 and 144 patients had died yielding a cumulative incidence of 26.1%, (95% CI 21.8-30.4) and 37.8% (95% CI 32.8-42.9), respectively. The main cause of death was underlying cancer. Conclusion In this prospective cohort of patients with cancer receiving LMWH for VTE, the Ottawa score did not accurately predict recurrent VTE. No other clinical predictor of recurrent VTE was identified in this study.

Abstract Purpose To assess survival trends after ST-elevation myocardial infarction (STEMI) in patients with a prior cancer diagnosis and to evaluate the drivers of prognosis over a follow-up period of five years. Methods Patients with a known cancer diagnosis, admitted with STEMI between 2004–2014 and treated with primary PCI were recruited from the STEMI-clinical registry of our institution. Detailed information on cancer diagnosis, -stage, and treatment regimen were collected from the institutional and national cancer registry system and all patients were followed prospectively. Results In the 215 included patients the cumulative incidence of all-cause death after 5 years of follow-up was 38.2% (N=61). The cause of death was predominantly malignancy-related (N=29, 47.4% of deaths) and only 9 patients (14.8% of deaths) died of a cardiovascular cause. After correcting for age and sex – a recent cancer diagnosis (<1yr relative to >10 yr, HR 3.405 [95% CI: 1.552–7.470], p=0.002), distant metastasis at presentation (HR 2.603 [1.236–5.481], p=0.012), ongoing cancer treatment at presentation (HR 1.878 [1.015–3.475], p=0.045) and natural logarithm of maximum creatinine kinase level (HR 1.345 [1.044–1.733], p=0.022) were significant predictors of long-term mortality. While prevalent renal insufficiency showed significant association with all-cause mortality (HR 2.302 [1.289–4.111], p=0.005), other known determinants of long-term prognosis after STEMI – a history of diabetes mellitus (HR 1.250 [0.566–2.761], p=0.581), hypertension (HR 0.623 [0.393–1.085], p=0.150), and culprit vessel left anterior descending artery or left main artery (HR 1.066 [0.641–1.771], p=0.806) were not significantly associated with survival at 5-years follow-up. Conclusion Cancer patients admitted with STEMI have a poor survival with one third of patients died at 5 year follow up.

Background: National and international guidelines for the diagnosis and treatment of cancer associated venous thromboembolism (CAT) recommend anticoagulation treatment for 3 to 6 months and a re-evaluation for resumption depending on the individual risk of every patient. In CAT low molecular weight heparin (LMWH) was estimated to be the most effective and safest treatment option in 2015. However, it remains unclear how cancer patients with VTE were (treated in clinical daily care in Germany. In former register trials, the specific characteristics of individual cancer patients were insufficiently characterized and inadequately discussed. Special aspects of daily care are lacking in most publications. Methods: The GECAT register was set up for Berlin´s two main hospital companies Charité-Universitaetsmedizin Berlin and Vivantes, (both covering about 50 % of the hospital beds in Berlin) to document prospectively patients with a newly diagnosed VTE . Patients with the diagnosis of cancer within 2 years prior to the VTE got basis documentation by a physician after informed consent. A follow up of these patients was scheduled after 3 and 6 months per telephone interview. Points of interest were: kind and location of the VTE event, diagnostic procedures, drug and dosage of initial and follow-up anti-coagulation treatment, relapse of VTE or bleeding complications, serious adverse events, mortality, and date and reason for determination of anticoagulation. Primary objective was to evaluate the treatment reality of patients with cancer associated VTE in clinical daily practice. Results: Between May 2015 and May 2017, 382 patients (pts) with active cancer within the last 2 years and newly diagnosed VTE gave consent to this register trial. 193 (50.5%) were female, median age was 65 years (range 19-89). For 133 pts (34.8%), VTE was the primary reason for admission at hospital, 34.3% were referred by their oncologist, 13,6% by their general practitioner, 15,5% by other treating physicians and 36.6% directly via the emergency department. 182 pts (47.6%) had pulmonary embolism, 268 pts (70.2%) had venous thrombosis and 18,6%71 pts (18.6%) had both. The most common cancer sites were lung (n=57, 14,9%), gynecological (n=44, 11,5%), colorectal (n=40, 10,5%) and pancreatic cancer (n=33 8,6%); 204 pts (56%) with solid tumors presented with stage IV diseases; 60 pts (15.7%) had hematological malignancies. 279 pts (73%) received anticancer treatments at the time of diagnosis of VTE. 148 (38.7%) pts died in the 6 months study period (20 pts died in hospital after admission, 90 pts within the first 3 months and 38 pts within the 6 months follow up). Initially, the majority of pts (n=350; 91.6%) was treated with LMWH. After discharge from hospital 78.7% remained on LMWH and 12.7% were treated with direct oral anticoagulants (DOACs). After 3 months 64.9% of pts received LMWH and 26.1% DOACs; after 6 months 48.4% LMWH and 44% DOACs. Responsible for the anticoagulation treatment decisions was mostly the oncologist (58%), followed by the general practitioner (26.3%) and other physicians (15,7%) . During the initial hospital stay, 2.6% of pts had a bleeding complication and 0.8% were diagnosed with a progress of VTE. At 6 months follow up, 6.4% reported bleeding complications and 2.4% recurrent VTE. Conclusion: The GECAT register trial gives new and clinically relevant information about the clinical daily care practice of cancer patients with newly diagnosed VTE in Berlin, Germany. The treating oncologist is in most cases responsible for the treatment.

Potential Use

SummaryCancer is a major and independent risk factor of venous thromboembolism (VTE). In clinical practice, a high number of VTE events occurs in patients with cancer, and treatment of cancerassociated VTE differs in several aspects from treatment of VTE in the general population. However, treatment in cancer patients remains a major challenge, as the risk of recurrence of VTE as well as the risk of major bleeding during anticoagulation is substantially higher in patients with cancer than in those without cancer. In several clinical trials, different anticoagulants and regimens have been investigated for treatment of acute VTE and secondary prophylaxis in cancer patients to prevent recurrence. Based on the results of these trials, anticoagulant therapy with low-molecular-weight heparins (LMWH) has become the treatment of choice in cancer patients with acute VTE in the initial period and for extended and long-term anticoagulation for 3-6 months. New oral anticoagulants directly inhibiting thrombin or factor Xa, have been developed in the past decade and studied in large phase III clinical trials. Results from currently completed trials are promising and indicate their potential use for treatment of VTE. However, the role of the new oral thrombin and factor Xa inhibitors for VTE treatment in cancer patients still has to be clarified in further studies specifically focusing on cancer-associated VTE. This brief review will summarize the current strategies of initial and long-term VTE treatment in patients with cancer and discuss the potential use of the new oral anticoagulants.

Current Management

AbstractOptimal management of venous thromboembolism (VTE) in cancer patients with thrombocytopenia is uncertain. We described current management and clinical outcomes of these patients. We retrospectively included a cohort of cancer patients with acute VTE and concomitant mild (platelet count 100,000–150,000/mm3), moderate (50,000–99,000/mm3), or severe thrombocytopenia (< 50,000/mm3). Univariate and multivariate logistic regression analyses explored the association between different therapeutic strategies and thrombocytopenia. The incidence of VTE and bleeding complications was collected at a 3-month follow-up. A total of 194 patients of whom 122 (62.89%) had mild, 51 (26.29%) moderate, and 22 (11.34%) severe thrombocytopenia were involved. At VTE diagnosis, a full therapeutic dose of LMWH was administered in 79.3, 62.8 and 4.6% of patients, respectively. Moderate (OR 0.30; 95% CI 0.12–0.75), severe thrombocytopenia (OR 0.01; 95% CI 0.00–0.08), and the presence of cerebral metastasis (OR 0.06; 95% CI 0.01–0.30) were independently associated with the prescription of subtherapeutic LMWH doses. Symptomatic VTE (OR 4.46; 95% CI 1.85–10.80) and pulmonary embolism (OR 2.76; 95% CI 1.09–6.94) were associated with the prescription of full therapeutic LMWH doses. Three-month incidence of VTE was 3.9% (95% CI 1.3–10.1), 8.5% (95% CI 2.8–21.3), 0% (95% CI 0.0–20.0) in patients with mild, moderate, and severe thrombocytopenia, respectively. The corresponding values for major bleeding and mortality were 1.9% (95% CI 0.3–7.4), 6.4% (95% CI 1.7–18.6), 0% (95% CI 0.0–20.0) and 9.6% (95% CI 5.0–17.4), 48.2% (95% CI 16.1–42.9), 20% (95% CI 6.6–44.3). In the absence of sound evidence, anticoagulation strategy of VTE in cancer patients with thrombocytopenia was tailored on an individual basis, taking into account not only the platelet count but also VTE presentation and the presence of cerebral metastasis.
