Abstract
INTRODUCTION Thromboembolic events have occurred in clinical trials of roxadustat. This post hoc analysis explored potential factors related to thromboembolic events in dialysis-dependent patients treated with roxadustat in four phase 3 clinical trials in Japan. METHODS Thromboembolic events with onset before and after week 12 were evaluated. Baseline risk factors for thromboembolic events were investigated by Cox regression analyses. Nested case-control analyses using conditional logistic models with matched pairs of case-control data explored relationships between thromboembolic events and laboratory parameters. RESULTS Of the 444 patients, 56 thromboembolic events were observed in 44 patients during ≤ 52 weeks of treatment. The proportion of venous and arterial thromboembolic events gradually increased after week 12. Baseline risk factors included hemodialysis (vs peritoneal dialysis), advanced age (≥ 65 years), shorter dialysis vintage (< 4 months), and history of thromboembolism. The absence of concomitant intravenous or oral iron therapy (including ferric citrate) was associated with thromboembolic events before week 12 (hazard ratio 11.25; 95% confidence interval [CI] 3.36-37.71; vs presence). Case-control analysis revealed that low average transferrin saturation (< 10%; unadjusted odds ratio [OR] 6.25; 95% CI 1.52-25.62; vs ≥ 20%), high average transferrin level (≥ 2.5 g/L; unadjusted OR 4.36; 95% CI 1.23-15.39; vs < 2.0 g/L), and high average roxadustat dose (≥ 150 mg; unadjusted OR 5.95; 95% CI 1.07-33.16; vs < 50 mg) over the previous 8 weeks before the event onset were associated with thromboembolic events after week 12. However, adjustment for iron status extinguished the significant relationship between roxadustat dose and events. Multivariate case-control analysis showed that increased transferrin from baseline (≥ 1.0 g/L; adjusted OR 7.85; 95% CI 1.82-33.90; vs < 0.5 g/dL) and decreased mean corpuscular volume (< - 2 fL; adjusted OR 5.55; 95% CI 1.73-17.83; vs ≥ 0 fL) were associated with increased risk of thromboembolic events. CONCLUSION In addition to established risk factors, iron deficiency may be related to thromboembolic events. Graphical Abstract available for this article.

Abstract
INTRODUCTION Risk factors for thromboembolic events in patients with dialysis-dependent chronic kidney disease (CKD) receiving roxadustat are unknown. Iron deficiency has been reported as a risk factor for thrombosis in the general population. METHODS Thromboembolic events with onset before and after week 12 in patients receiving roxadustat were evaluated in this pooled analysis of four global phase 3 trials, PYRENEES, SIERRAS, HIMALAYAS, and ROCKIES. Baseline risk factors for thromboembolic events were investigated by Cox regression analyses. Nested case-control analyses with matched pairs of case-control data explored the relationship between thromboembolic events and last known laboratory parameters before event onset. RESULTS Of 2354 patients, 1026 thromboembolic events were observed in 568 patients. Baseline risk factors found included hemodialysis (vs peritoneal dialysis), advanced age (≥ 65 years), Black race, high high-sensitivity C-reactive protein, and history of thromboembolism, cardiovascular disease, or diabetes. Univariate case-control analyses revealed that high hemoglobin rate of rise (≥ 0.5 g/dL/week; odds ratio [OR] 2.09; 95% confidence interval [CI] 0.98-4.46) showed a trend towards increased risk of thromboembolic events before week 12, and high rate of hemoglobin decline was associated with events after week 12 (< - 0.5 g/dL/week; OR 3.73; 95% CI 1.68-8.27) as compared to stable hemoglobin levels (≥ - 0.1 to < 0.1 g/dL/week). Multivariate case-control analyses showed that low last known hemoglobin level (< 10 g/dL: adjusted OR 1.91; 95% CI 1.04-3.50; vs ≥ 12 g/dL) and low last known transferrin saturation (TSAT < 10%: adjusted OR 3.78; 95% CI 1.71-8.39; vs ≥ 30%) before event onset were associated with events after week 12. In patients with last known TSAT < 30%, higher roxadustat dose was associated with thromboembolic events; however, no association was observed in those with TSAT ≥ 30%. CONCLUSIONS Among various risk factors for thromboembolic events, it is reasonable to avoid a rapid increase and decline in hemoglobin levels as well as ensure TSAT ≥ 30%, rather than increasing the roxadustat dose.

Abstract
OBJECTIVE Patients with ovarian cancer have a high risk of developing thrombosis. We aimed to investigate laboratory parameters associated with deep vein thrombosis (DVT) in patients treated for ovarian cancer. METHODS We retrospectively analyzed pre-operation laboratory data of patients with ovarian cancer for DVT at the National Cancer Center, Korea, between January 2000 and February 2021. The test items were white blood cell count, absolute neutrophil count (ANC), hemoglobin, platelets, monocytes, serum glucose, CA125, D-dimer, fibrinogen, prothrombin time (PT), activated partial thromboplastin time (aPTT), and body mass index (BMI). Differences between patients with and without DVT were compared with Wilcoxon rank-sum test. We analyzed the variables using logistic regression. Items with significant odds ratios were included in multivariate logistic regression. Significant variables were selected using backward elimination. Items were further categorized based on reference ranges. Univariate and multivariate analyses were performed to identify items with abnormal values associated with DVT. RESULTS From 3,147 patient samples analyzed, 286 (9.1%) patients with DVT were selected. Differences between patients with vs without DVT were statistically significant for hemoglobin, monocyte, serum glucose, CA125, PT, aPTT, fibrinogen, D-dimer, and BMI. After univariate and multivariate analysis, monocyte, glucose, and PT remained significant. Among the categorical variables, low hemoglobin, high monocyte, high CA125, prolonged PT, and high BMI remained significant after univariate and multivariate analysis. CONCLUSION Pre-operation laboratory data of low hemoglobin, high monocyte percentage, high serum glucose, high CA125, prolonged PT, and high BMI were associated with DVT.

Abstract
Cancer-associated anemia promotes tumor progression, leads to poor quality of life in patients with cancer, and even obstructs the efficacy of immune checkpoint inhibitors therapy. However, the precise mechanism for cancer-associated anemia remains unknown and the feasible strategy to target cancer-associated anemia synergizing immunotherapy needs to be clarified. Here, we review the possible mechanisms of cancer-induced anemia regarding decreased erythropoiesis and increased erythrocyte destruction, and cancer treatment-induced anemia. Moreover, we summarize the current paradigm for cancer-associated anemia treatment. Finally, we propose some prospective paradigms to slow down cancer-associated anemia and synergistic the efficacy of immunotherapy. Video Abstract.

Abstract
Erythropoiesis‐stimulating agents (ESA) are effective for chemotherapy‐induced anemia (CIA) but associated with serious adverse events. Safer alternatives would be beneficial in this population. The efficacy and safety of ferric carboxymaltose (FCM) as monotherapy for CIA was evaluated. This Phase 3, 18‐week, double‐blind, placebo‐controlled study randomized adults with ≥ 4 weeks of chemotherapy remaining for treatment of nonmyeloid malignancies with CIA to FCM (two 15 mg/kg infusions 7 days apart; maximum dose, 750 mg single/1500 mg total) or placebo. The primary efficacy endpoint was percentage of patients with decreases in hemoglobin (Hb) ≥ 0.5 g/dL from weeks 3 to 18; the key secondary efficacy endpoint was change in Hb from baseline to week 18. Inclusion criteria included: (Hb) 8–11 g/dL, ferritin 100–800 ng/mL, and transferrin saturation (TSAT) ≤35%. In 244 patients (n = 122, both groups), the percent of patients who maintained Hb within 0.5 g/dL of baseline from weeks 3 to 18 was significantly higher with FCM versus placebo (50.8% vs. 35.3%; p = 0.01). Mean change in Hb from baseline to week 18 was similar between FCM and placebo (1.04 vs. 0.87 g/dL) but significantly greater with FCM with baseline Hb ≤ 9.9 g/dL (1.08 vs. 0.42 g/dL; p = 0.01). The percent with ≥ 1 g/dL increase from baseline was significantly higher with FCM versus placebo (71% vs. 54%; p = 0.01), occurring in a median 43 versus 85 days (p = 0.001). Common adverse events in the FCM arm included neutropenia (17%), hypophosphatemia (16%), and fatigue (15%). FCM monotherapy effectively maintained Hb and was well tolerated in CIA.

Abstract
INTRODUCTION The risk of venous thromboembolism (VTE) varies among tumour types, and different cancer type-specific risks for VTE prediction remain undefined. We aimed to establish a prediction model for non-small lung cancer (NSCLC)-associated VTE. MATERIALS AND METHODS We analysed data from a prospective cohort of patients with newly diagnosed NSCLC. We then developed a VTE risk prediction model using data of patients who were recruited from 2013 to 2017 (n = 602, development cohort) and validated this model using date of patients recruited from 2018 to 2019 (n = 412, validation cohort). The cumulative 6 months VTE incidence observed in both cohorts was calculated. RESULTS The parameters in this new model included Eastern Cooperative Oncology Group (ECOG) performance status ≥2 (1 point), EGFR mutation (-1 point), neutrophil count ≥7.5 × 109/L (2 points), hemoglobin <115 g/L (1 point), CEA ≥5.0 ng/mL (2 points), and D-dimer level ≥1400 ng/mL (4 points). The cross-validated concordance indices of the model in the development and validation cohorts were 0.779 and 0.853, respectively. Furthermore, the areas under the curve in the two cohorts were 0.7563 (95% confidence interval [CI]: 0.6856-0.8129, P < 0.001) and 0.8211 (95% CI: 0.7451-0.8765, P < 0.001) for development and validation cohorts, respectively. CONCLUSIONS The new VTE risk prediction model incorporated patient characteristics, laboratory values, and oncogenic status, and was able to stratify patients at high risk of VTE in newly diagnosed NSCLC within 6 months of diagnosis.

Abstract
Purpose To explore the relationship between venous thromboembolism (VTE) and early mortality (within six months) in Chinese patients with newly diagnosed metastatic non-small cell lung cancer (NSCLC) after entering the era of precision treatment. Methods A cohort of 706 consecutive subjects with newly diagnosed metastatic NSCLC were prospectively observed. Clinical and survival data were recorded over a six-month follow-up period. The predictive factors for the occurrence of VTE and the relationship with early mortality were evaluated through univariate and multivariate analyses. Results During the six-month follow-up period, VTE events occurred in 12.2% (86/706) of the enrolled patients. In the multivariate analyses for VTE, an age older than 70 years (vs < 70: sub-distribution hazard radio [SHR], 1.678; 95% confidence interval (CI), 1.073–2.600; P=0.022), an Eastern Cooperative Oncology Group performance status ≥2 (vs 0/1: SHR, 1.946; 95% CI, 1.277–2.970; P=0.002), and having an ALK rearrangement (vs non-rearrangement: SHR, 2.377; 95% CI, 1.186–4.760; P=0.015) were significantly associated with the occurrence of VTE. Within six months, 116 subjects (16.4%) died, and the occurrence of VTE (vs no VTE: adjusted HR: 1.863; 95% CI: 1.178–2.947, P=0.008) was remarkably associated with early mortality. Further analysis showed 98 patients (13.9%) with early mortality had EGFR/ALK wild-type genes, with a risk of early mortality 5.935-fold higher than that of patients with an EGFR mutation/ALK rearrangement. Finally, subgroup analyses showed that VTE occurrence was a significant factor for predicting early mortality in patients with EGFR/ALK wild-type genes (adjusted HR: 1.682; 95% CI: 1.023–2.768, P=0.041). Conclusion Patients with an EGFR mutation/ALK rearrangement had a significantly decreased risk of early mortality in the era of targeted therapy; however, VTE occurrence remained an important predictor for early mortality in metastatic NSCLC patients, especially in patients with EGFR/ALK wild-type genes.

Abstract
Despite increasing use of targeted therapies to treat cancer, anemia remains a common complication of cancer therapy. Physician concerns about the safety of intravenous (IV) iron products and erythropoiesis-stimulating agents (ESAs) have resulted in many patients with cancer receiving no or suboptimal anemia therapy. In this article, we present 4 patient cases that illustrate both common and complex clinical scenarios. We first present a review of erythropoiesis and then describe our approach to cancer-associated anemia by identifying the contributing causes before selecting specific treatments. We summarize clinical trial data affirming the safety and efficacy of currently available IV iron products used to treat cancer-associated anemia and illustrate how we use commonly available laboratory tests to assess iron status during routine patient management. We compare adverse event rates associated with IV iron vs red cell transfusion and discuss using first-line IV iron monotherapy to treat anemic patients with cancer, which decreases the need for ESAs. A possible mechanism behind ESA-induced tumor progression is discussed. Finally, we review the potential of novel therapies such as ascorbic acid, prolyl hydroxylase inhibitors, activin traps, hepcidin, and bone morphogenetic protein antagonists in treating cancer-associated anemia.

Abstract
Iron deficiency (ID) is globally prevalent, and apart from anemia is associated with thrombocytosis. While considered benign, studies linking thrombotic events with prior ID anemia suggest otherwise. In this study we used animal models to assess the influence of ID on thrombotic tendency. Sprague-Dawley rats were fed control or iron-deficient diets and ferric carboxymaltose was used to reverse ID. Thrombosis was induced by stenosis of the inferior vena cava or damage to the right carotid artery using ferric chloride. Thrombi were evaluated histologically and by high frequency ultrasound in the venous model. ID consistently induced thrombocytosis alongside anemia. The growth of venous thrombi and the final dimensions of both arterial and venous thrombi were greater in animals with ID. In both models, platelet numbers correlated with the final thrombus size, with thrombi in iron-deficient animals having the largest platelet areas. Platelet function was also evaluated in surgically-naïve rats. Coagulability, determined by thromboelasto - graphy, and hemostasis, evaluated by tail transection, were enhanced in the animals with ID. Platelet P-selectin expression and plasma P-selectin levels were both higher in animals with ID. Platelet adhesion and aggregation in ID was impaired under shear flow but was intact in static assays. Iron replacement therapy reversed all ID-related changes in hematologic parameters, thrombus dimensions, and platelet assays. In summary, ID alone increases thrombotic tendency. Iron replacement therapy reverses these changes, making it a viable strategy for the prevention of ID-related thrombotic disease. This may be of importance in patients with chronic illnesses who may already be at increased risk of thrombosis, such as those with inflammatory bowel disease, chronic kidney disease, or cancer.

Abstract
BACKGROUND Over the last decade, preoperative anemia has become recognized as a clinical condition in need of management. Although the etiology of preoperative anemia can be multifactorial, two-thirds of anemic elective surgical patients have iron deficiency anemia. At the same time, one-third of non-anemic elective surgical patients are also iron deficient. METHODS Modified-RAND Delphi methodology was employed to identify areas of consensus among an expert panel regarding the management of iron deficiency in patients undergoing cardiac surgery. A list of statements was sent to panel members to respond to using a five-point Likert Scale. All panel members subsequently attended a face-to-face meeting. The initial survey was presented and discussed, and panel members responded to each statement on the Likert scale again. Based on the second survey, the panel came to a consensus on recommendations. RESULTS The panel recommended all patients undergoing cardiac surgery be evaluated for iron deficiency, whether or not anemia is present. Evaluation should include iron studies and reticulocyte hemoglobin content. If iron deficiency is present, with or without anemia, patients should receive parenteral iron. Erythropoietin stimulating agents may be appropriate for some patients. CONCLUSIONS Consensus of an expert panel resulted in a standardized approach to diagnosing and managing iron deficiency in patients undergoing cardiac surgery.

Abstract
Background Intravenous iron is often used to treat iron deficiency anaemia in non-dialysis chronic kidney disease (ND-CKD), but the optimal dosing regimen remains unclear. We evaluated the impact of high- versus low-dose intravenous iron isomaltoside on the probability of retreatment with intravenous iron in iron-deficient ND-CKD patients. Methods This real-world, prospective, observational study collected data from 256 ND-CKD patients treated for anaemia in the UK. Following an initial course of iron isomaltoside, patients were followed for ≥12 months. Iron dose and the need for retreatment were determined at the investigators’ discretion. The primary study outcome was the need for retreatment at 52 weeks compared between patients who received >1000 mg of iron during Course 1 and those who received ≤1000 mg. Safety was evaluated through adverse drug reactions. Results The probability of retreatment at Week 52 was significantly lower in the >1000 mg iron group (n = 58) versus the ≤1000 mg group (n = 198); hazard ratio (95% confidence interval [CI]): 0.46 (0.20, 0.91); p = 0.012. Mean (95% CI) haemoglobin increased by 6.58 (4.94, 8.21) g/L in the ≤1000 mg group and by 10.59 (7.52, 13.66) g/L in the >1000 mg group (p = 0.024). Changes in other blood and iron parameters were not significantly different between the two groups. Administering >1000 mg of iron isomaltoside saved 8.6 appointments per 100 patients compared to ≤1000 mg. No serious adverse drug reactions were reported. Of the patients who received ≤1000 mg of iron in this study, 82.3% were eligible for a dose >1000 mg. Conclusions The >1000 mg iron isomaltoside regimen reduced the probability of retreatment, achieved a greater haemoglobin response irrespective of erythropoiesis-stimulating agent treatment, and reduced the total number of appointments required, compared to the ≤1000 mg regimen. Many of the patients who received ≤1000 mg of iron were eligible for >1000 mg, indicating that there was considerable underdosing in this study. Trial registration ClinicalTrials.gov NCT02546154, 10 September 2015.

Abstract
Background Patients receiving a variety of chemotherapy regimens often develop chemotherapy‐induced anemia (CIA), which contributes to poor outcomes including increased mortality. Prompt and effective treatment of CIA is essential to prevent fewer chemotherapy dose delays and reductions. Optimal therapy of CIA is controversial and involves the solitary and combined use of intravenous iron, red blood cell (RBC) transfusions, and erythropoietin stimulating agents (ESAs). Despite the baseline coagulopathies present in patients with malignancy, administration of both RBC transfusions and ESAs is associated with venous thromboembolism (VTE). It remains unknown whether the risk of VTE in patients with CIA is greater among patients who receive RBC transfusions or ESAs. Methods A retrospective study analyzed 10,269 University of Pennsylvania Health System patients with malignancies of various type, stage, and histopathology who developed CIA between 2008 and 2017. Using multivariate Cox regression, we determined adjusted hazard ratios (and corresponding 95% confidence intervals) of VTE development after adjusting for RBC and ESA intervention (all during the 90 days following CIA diagnosis). Results Among the 10,269 patients with CIA, 2,642 (25.7%) developed a VTE within the 90‐day period. VTE risk following RBC transfusion (HR = 1.37, 95% CI 1.24‐1.50, P < .001) was more than twice as common as VTE risk following ESA administration (HR = 0.53, 95% CI 0.40‐0.69, P < .001). Conclusion While both RBC transfusion and ESA are independently associated with VTE, our data suggest a greater risk of VTE development with RBC transfusion as compared with ESA.

Abstract
BACKGROUND In this study, we investigate the incidence of venous thrombosis (VT), and evaluate the effectiveness and safety of 3 major thromboprophylaxes and the potential risk factors for VT in women undergoing surgery for a gynecological malignancy. METHODS We performed a randomized controlled trial of 307 patients undergoing laparoscopic surgery for gynecological malignancies at a single institution from January 2016 to October 2017. Patients were divided into 3 groups: one receiving a half dose of low-molecular-weight heparin sodium injection (FLUXUM, Alfa Wassermann, Italy) delivered by injection, one receiving a full dose of FLUXUM, and a third group receiving an Argatroban injection. RESULTS None of the patients in our study developed a pulmonary embolism, bleeding, or infectious complications. There were no statistical differences in the rate of deep venous thrombosis (DVT) (0%, 0%, and 2.38%) and the superficial venous thromboembolism (SVT) (15.66%, 8.97%, and 18.6%) among the 3 groups. None of the patients developed symptomatic VT. The effect of treatment on alanine aminotransferase and aspartate aminotransferase differed between the groups, with a minimal effect in the Argatroban group, and all 3 methods resulted in minimal impairment of renal function. Decreased hemoglobin, elevated levels of D-dimer, and prothrombin time were closely related to thrombogenesis. CONCLUSION In conclusion, the incidence of postoperative thrombosis in gynecological malignancy among these Chinese people is not as low as we had originally presumed. Argatroban is not more effective than Parnaparin as a direct thrombin inhibitor, but it has less influence on liver function, which is beneficial for patients undergoing chemotherapy. Hemoglobin, D-dimer, and prothrombin time may be used to predict or detect thrombogenesis.

Abstract
BACKGROUND Biologics are widely used to manage the side effects of cancer treatment (e.g., epoetin alfa is used to treat chemotherapy-induced anemia [CIA] and granulocyte colony-stimulating factors [G-CSFs] are used to treat chemotherapy-induced neutropenia [CIN]). As several patents for biologics used in cancer treatment have expired, a number of companies have developed supportive care biosimilars (e.g., epoetin alfa biosimilar, filgrastim biosimilar, pegfilgrastim biosimilar). OBJECTIVE The objective of this study was to synthesize current evidence on the efficacy and safety of supportive care biosimilars compared with their reference biologics in oncology. METHODS We searched PubMed, Embase, the Cochrane library, ClinicalTrials.gov, ISI Web of Science and several Chinese databases from their inception dates to December 31, 2018 for randomized controlled trials (RCTs) or comparative observational studies that compared the efficacy and safety of supportive care biosimilars and their reference biologics in oncology. We pooled results separately for RCTs and observational studies, as such studies involve different patient populations and are designed differently. We pooled binary outcomes using risk ratios (RR) with confidence intervals (CIs) and continuous outcomes using weighted mean differences (WMD) with 95% CIs, then conducted subgroup and sensitivity analyses. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to rate the quality of evidence. RESULTS We identified 28 studies that compared biosimilars of G-CSF or epoetin alfa: one RCT and five cohort studies (total N = 2816) of epoetin alfa biosimilars, and 13 RCTs and 9 cohort studies (total N = 23,043) of G-CSF biosimilars [corrected]. Despite involving different populations, RCTs and observational studies comparing biosimilars and reference biologics indicated similar efficacy and safety results. Overall, there was no statistically significant difference in any efficacy or safety outcomes between any biosimilars and their corresponding original biologics (all p > 0.05). The quality of GRADE evidence of efficacy and safety outcomes was moderate or low. Findings were robust for all prespecified subgroup and sensitivity analyses. CONCLUSION Existing evidence suggests highly comparable efficacy and safety profiles for supportive care biosimilars and their reference biologics in oncology.

Abstract
PURPOSE OF REVIEW Sotatercept and luspatercept are recombinant soluble activin type-II receptor-IgG-Fc fusion proteins that are tested in clinical trials for the treatment of various types of anemias, including renal anemia. The mechanism of the action of the novel drugs is incompletely understood, but it seems to be based on the inactivation of soluble proteins of the transforming growth factor-ß (TGFß) family. This review considers pros and cons of the clinical use of the drugs in reference to the current therapy with recombinant erythropoiesis-stimulating agents (ESAs). RECENT FINDINGS One or more activin type-II receptor (ActRII) ligands appear to inhibit erythroid precursors, for example growth and differentiation factor 11. Trapping of these ligands by the recombinant ActRII fusion proteins, sotatercept and luspatercept increases red blood cell numbers and hemoglobin levels in humans. Reportedly, the novel compounds were well tolerated in trials on healthy volunteers and patients suffering from anemia due to chronic kidney disease or malignancies. On approval, the drugs may prove particularly useful in patients suffering from ineffective erythropoiesis, such as in myelodysplastic syndrome, multiple myeloma or ß-thalassemia, where ESAs are of little use. Independent of their effect on erythropoiesis, ActRII ligand traps were found to exert beneficial effects on renal tissue in experimental animals. SUMMARY ESAs are likely to remain standard of care in renal anemia. There is a need for a better understanding of the effects of ActRII ligand traps on TGFß-like proteins. The novel drugs have not been approved for sale as therapeutics so far. Their long-term efficacy and safety still needs to be proven, particularly with respect to immunogenicity. Antifibrotic effects may be worthy to be investigated in humans.

Abstract
BACKGROUND Supportive care of Jehovah's Witnesses (JWs) diagnosed with cancer can be challenging, as they do not accept red blood cell (RBC) transfusions. AIM The study was designed to determine treatment preferences and pattern of care offered to JWs diagnosed with cancer and its impact on cancer management. METHODS AND RESULTS A retrospective cohort study of JWs with solid malignancies or lymphoma in our institution between 2005 and 2015 was conducted. Survival statistics were estimated using Kaplan Meier survival curves and Cox proportional regression model. A total of 63 JWs were identified with a median age of 70 years. At diagnosis, 34% (n = 22) had anaemia. All 63 declined RBC transfusion, including 19 patients who later developed transfusion threshold during anti-cancer treatment. Forty-three percent (n = 27) JWs had advanced (stage 4) disease, and 76% (n = 48) had Eastern Cooperative Oncology Group of 0 to 1. JWs were willing to accept surgery and radiation rather than chemotherapy. Treatment was deemed to be suboptimal in 22% (n = 14) JWs due to early treatment discontinuation, administration of non-standard chemotherapy regimen, or dose reduction due to anaemia and denial of blood transfusion. Twenty-seven percent (n = 17) received hematopoietic growth factors (erythropoiesis-stimulating agents and pegfilgrastim). There was no mortality directly attributed to anaemia or refusal of blood transfusion in the entire cohort. CONCLUSION Jehovah's Witnesses declined RBC transfusion at diagnosis and during cancer therapy even if medically indicated. Management pathways need to be prospectively defined for this group of patients.

Abstract
Despite numerous guidelines on the management of anaemia in surgical patients, there is no pragmatic guidance for the diagnosis and management of anaemia and iron deficiency in the postoperative period. A number of experienced researchers and clinicians took part in a two-day expert workshop and developed the following consensus statement. After presentation of our own research data and local policies and procedures, appropriate relevant literature was reviewed and discussed. We developed a series of best-practice and evidence-based statements to advise on patient care with respect to anaemia and iron deficiency in the postoperative period. These statements include: a diagnostic approach to iron deficiency and anaemia in surgical patients; identification of patients appropriate for treatment; and advice on practical management and follow-up that is easy to implement. Available data allow the fulfilment of the requirements of Pillar 1 of Patient Blood Management. We urge national and international research funding bodies to take note of these recommendations, particularly in terms of funding large-scale prospective, randomised clinical trials that can most effectively address the important clinical questions and this clearly unmet medical need.

Abstract
BACKGROUND Anemia is a common finding and independent predictor for adverse outcomes in hospitalized patients with medical illness. It remains unclear whether anemia is a risk factor for venous thromboembolism and whether the presence of anemia can refine risk assessment for prediction of venous thromboembolism, thereby adding incremental utility to a validated model. METHODS In the Acute Medically Ill Venous Thromboembolism Prevention with Extended Duration Betrixaban trial (APEX), 7513 hospitalized medical patients were randomized to receive either betrixaban or standard-of-care enoxaparin for thromboprophylaxis. Baseline hemoglobin concentrations were obtained in 6861 patients, with a follow-up of 77 days. Symptomatic venous thromboembolism events, including symptomatic deep vein thrombosis, pulmonary embolism, and venous thromboembolism-related mortality, were compared between low-hemoglobin and normal-hemoglobin groups (normal range: 12.5-17.0 g/dL for males and 11.0-15.5 g/dL for females). The relationship between anemia and venous thromboembolism events was assessed by fitting a univariable and multivariable logistic regression model composed of thromboprophylaxis and risk factors. Venous thromboembolism risk refinement by hemoglobin measurement was evaluated in the International Medical Prevention Registry on Venous Thromboembolism (IMPROVE) risk assessment model. RESULTS Low hemoglobin at baseline was associated with a greater risk of symptomatic venous thromboembolism (relative risk [RR] 1.94 [95% confidence interval, 1.27-2.98]; P = .002), symptomatic deep vein thrombosis (RR 2.29 [1.12-4.68]; P = .019), and nonfatal pulmonary embolism (RR 2.63 [1.22-5.65]; P = .010) but not venous thromboembolism-related mortality (RR 1.47 [0.71-3.04]; P = .30). After adjusting for thromboprophylaxis, history of previous venous thromboembolism, intensive or coronary unit admission, and D-dimer, low hemoglobin (as a categorical or continuous variable) remained associated with an increased likelihood of venous thromboembolism (adjusted odds ratio 1.71 [95% confidence interval, 1.09-2.69]; P = .020). Low hemoglobin also improved risk discrimination and reclassification after inclusion in the IMPROVE model. CONCLUSIONS Anemia was independently associated with a greater risk of symptomatic venous thromboembolism among acutely ill medical patients despite the provision of thromboprophylaxis. Hemoglobin measurement also improved risk stratification by the IMPROVE venous thromboembolism risk score.

Abstract
Venous thromboembolism (VTE) is a typical complication in patients with lung cancer. Khorana score is an established tool for thromboembolic risk stratification of ambulatory patients with cancer undergoing outpatient chemotherapy. The aim of this study was to evaluate the predictive value of the Khorana score for VTE and death in patients with lung adenocarcinoma during first-line or adjuvant chemotherapy. Medical records of 130 patients with lung adenocarcinoma receiving first-line or adjuvant chemotherapy were retrospectively studied during the time period June 2013 to May 2015. Venous thromboembolism occurred in 13 (10.0%) patients. Thromboembolic events were significantly correlated with reduced survival during treatment period (hazard ratio [HR]: 3.24; 95% confidence interval [CI]: 1.11-9.49; P = .032). The VTE rates did not present statistically significant difference between different Khorana score groups ( P = .96). In univariate analysis, the risk of death during treatment period (median: 16 weeks) was 3.75 times higher in high-risk versus intermediate-risk patients (HR: 3.75, 95% CI: 1.36-10.36; P = .001) and had 2.25 times higher per point increase in the Khorana score (HR: 2.25, 95% CI: 1.36-3.73; P = .002); the above results were also reproduced in multivariate analysis. Khorana score represents a valuable tool for identifying patients with cancer in low thromboembolic risk but does not preserve its predictive value for higher risk individuals. Khorana score is an independent risk factor for death in patients with lung adenocarcinoma receiving first-line or adjuvant chemotherapy.

Abstract
The prevention and treatment of iron deficiency is a major public health goal. Challenges in the treatment of iron deficiency include finding and addressing the underlying cause and the selection of an iron replacement product which meets the needs of the patient. However, there are a number of non-evidence-based misconceptions regarding the diagnosis and management of iron deficiency, with or without anaemia, as well as inconsistency of terminology and lack of clear guidance on clinical pathways. In particular, the pathogenesis of iron deficiency is still frequently not addressed and iron not replaced, with indiscriminate red cell transfusion used as a default therapy. In our experience, this imprudent practice continues to be endorsed by non-evidence-based misconceptions. The intent of the authors is to provide a consensus that effectively challenges these misconceptions, and to highlight evidence-based alternatives for appropriate management (referred to as key points). We believe that this approach to the management of iron deficiency may be beneficial for both patients and healthcare systems. We stress that this paper solely presents the Authors' independent opinions. No pharmaceutical company funded or influenced the conception, development or writing of the manuscript.

Abstract
Purpose Iron deficiency anemia (IDA) is common in cancer patients due to blood loss and inflammation. Many do not tolerate oral iron or adequately respond. Intravenous (IV) iron is commonly used as an adjunct to erythropoiesis-stimulating agents; data on the use of IV iron monotherapy in these patients are limited. This study aimed to evaluate IV ferumoxytol for the treatment of cancer patients with IDA with a history of unsatisfactory oral iron therapy or in whom oral iron could not be used. Patients and methods This post hoc analysis of pooled data from two multicenter, randomized, controlled, Phase III trials evaluating IV ferumoxytol (510 mg ×2) vs placebo or iron sucrose (200 mg ×5) included a subgroup of 98 patients with cancer that the investigator identified as the primary cause of their IDA, or with cancer whose IDA was attributed to another comorbid condition (ferumoxytol, n=75; iron sucrose, n=13; placebo, n=10). Gastrointestinal cancers were most common (42), followed by breast (14), cervix (ten), and lung (nine). The primary endpoint was the mean change in hemoglobin (Hgb) from baseline to week 5. Results At week 5, both ferumoxytol and iron sucrose produced significant increases in Hgb from baseline (1.8 g/dL [P<0.0001] and 1.9 g/dL [P=0.002], respectively). During the studies, 45 patients received chemotherapy, 19 with platinum-based regimens. Erythropoiesis-stimulating agent doses were neither increased >20% nor initiated in any treatment group. Overall rates of adverse events and serious adverse events in the cancer subgroup mirrored those in the overall study population. Conclusion Monotherapy with IV iron appears to be an effective option for cancer patients with IDA who do not respond to or cannot tolerate oral iron therapy.

Abstract
INTRODUCTION Disorders of iron metabolism are commonly seen in onco-hematological clinical practice. Iron-deficiency anemia and cancer-associated anemia are usually treated with supportive therapies. Optimal management of these conditions are discussed in this perspective paper. Areas covered: A position paper discussing a number of hot topics on anemia in cancer patients is presented. The main areas covered by experts in the field are: definitions, prevalence and consequences of anemia and iron deficiency, incidence of anemia resulting from targeted therapies, importance of anemia diagnosis and monitoring, evaluation of iron status before and during treatment, role of transfusions and erythropoiesis-stimulating agents, management of iron deficiency with or without anemia, parenteral iron supplementation, role of new oral iron formulations, safety and cost issues regarding different iron compounds and administration routes. Expert commentary: Despite the availability of newer therapeutic options for its management, anemia still represents a major complication of treatment in cancer patients (surgery, chemotherapy, radiotherapy, targeted therapies), aggravating physical impairment, and negatively affecting general outcome. The view expressed by the panelists, attendees of the 4th Mediterranean Course on Iron Anemia, summarizes what they consider optimal clinical practice for screening, diagnosis, treatment and monitoring of iron deficiency and anemia in cancer patients.

Abstract
Platelets are anucleate cells in the blood at concentrations of 150,000 to 400,000 cells/µL and play a key role in hemostasis. Several studies have suggested that platelets contribute to cancer progression and cancer-associated thrombosis. In this review, we provide an overview of the biochemical and biophysical mechanisms by which platelets interact with cancer cells and review the evidence supporting a role for platelet-enhanced metastasis of cancer, and venous thromboembolism (VTE) in patients with cancer. We discuss the potential for and limitations of platelet counts to discriminate cancer disease burden and prognosis. Lastly, we consider more advanced diagnostic approaches to improve studies on the interaction between the hemostatic system and cancer cells.

Abstract
Hemoglobin optimization and treatment of preoperative anemia in surgery with a moderate to high risk of surgical bleeding reduces the rate of transfusions and improves hemoglobin levels at discharge and can also improve postoperative outcomes. To this end, we need to schedule preoperative visits sufficiently in advance to treat the anemia. The treatment algorithm we propose comes with a simple checklist to determine whether we should refer the patient to a specialist or if we can treat the patient during the same visit. With the blood count test and additional tests for iron metabolism, inflammation parameter and glomerular filtration rate, we can decide whether to start the treatment with intravenous iron alone or erythropoietin with or without iron. With significant anemia, a visit after 15 days might be necessary to observe the response and supplement the treatment if required. The hemoglobin objective will depend on the type of surgery and the patient's characteristics.

Abstract
Iron deficiency, the most common nutritional deficiency worldwide, is often associated with reactive thrombocytosis. Although secondary thrombocytosis is commonly considered to be harmless, there is accumulating evidence that elevated platelet counts, especially in the setting of iron deficiency, can lead to an increased thromboembolic risk in both arterial and venous systems. Here we present the mechanisms of iron deficiency-induced thrombocytosis and summarize its clinical consequences especially in patients with inflammatory bowel diseases, chronic kidney disease or cancer. We hypothesize that iron deficiency is an underestimated thromboembolic risk factor, and that iron replacement therapy can become an effective preventive strategy in a variety of clinical settings.

Abstract
OBJECTIVE To evaluate the risk of thromboembolic and pulmonary toxicities associated with hematopoietic growth factor (HGF) use (i.e., erythropoietin-stimulating agent [ESA] and/or colony-stimulating factor [CSF]) in a community-dwelling cohort of elderly patients with advanced ovarian cancer. METHODS We studied 8,188 women, 65 years and older from the Surveillance, Epidemiology and End Results-Medicare linked database, diagnosed from January 1, 2000 to December 31, 2009. Patients were categorized into five groups: no chemotherapy and no ESA/CSF (n = 2,616), chemotherapy but no ESA/CSF (n = 1,854), ESA only (n = 1,313), CSF only (n = 743), and ESA + CSF (n = 1,662). We reported the cumulative incidence of toxicities for 2, 6, and greater than 6 months, and the incidence density for the overall follow-up. Cox-proportional hazards regression was performed to determine risk of toxicities. RESULTS Of the 5,572 patients receiving chemotherapy, 66.7% (n = 3,718) received HGF supportive treatment, 29.8% received ESA + CSF, 23.6% received ESA only, and 13.3% received CSF only. Patients who received chemotherapy and also ESA + CSF had a 14.1% cumulative incidence of thromboembolic event (TEE) at 6 months of follow-up compared with 8.0% in those who received chemotherapy without growth factor and 3.2% in those with neither chemotherapy nor growth factor. Those with chemotherapy who received ESA + CSF had a significantly higher risk of TEE (adjusted hazard ratio, 1.22; 95% confidence interval, 1.01-1.47) as compared with patients with chemotherapy and no ESA/CSF, although patients aged 85 years and older may experience up to a five-fold increased risk. The risk of pulmonary toxicities did not significantly differ by HGF use. CONCLUSIONS An increased risk of TEEs was observed in elderly patients with ovarian cancer who received ESA + CSF. The risk-benefit ratio for administering HGF should be carefully evaluated, especially among those 85 years and older.

Abstract
Higher doses of erythropoiesis-stimulating agents (ESAs) contribute to atherothrombotic cardiovascular disease in hemodialysis (HD) patients. Thrombocytosis is associated with increased mortality in ESA-treated HD patients. We investigated variables affecting platelet count and its variability (platelet count increment [Δplatelet count]) in HD patients. This retrospective longitudinal and observational study of HD outpatients was carried out over 3 years. The outcome was independent determinants of platelet count and Δplatelet count, which were associated with iron indices, ESA dose, and C-reactive protein. In univariate regression analysis, V-shaped relationship was observed between platelet count and transferrin saturation (TSAT), ferritin, serum iron, and hemoglobin (Hb) with the bottom of 0.21, 330 ng/mL, 49 µg/dL, and 10.3 g/dL, respectively. Mixed-effect multivariate regression analysis revealed that TSAT (inversely), Hb ≤10.3 g/dL (inversely), C-reactive protein, and ESA dose were independently associated with platelet count. Δplatelet count was independently and inversely correlated with ΔTSAT and directly correlated with Δferritin. TSAT was independently and inversely associated with ESA dose. ESA dose was directly correlated with iron dose and inversely correlated with TSAT, ferritin ≤330 ng/mL, and Hb ≤10.3 g/dL. ESA dose and TSAT were correlated in determining platelet count and Δplatelet count. Targets of iron indices that reflect iron supply sufficient to avoid platelet count increment and variability may be >21% of TSAT and 300 ng/mL of serum ferritin for appropriate ESA therapy in HD patients.

Abstract
Preoperative anemia in patients with cancer is highly prevalent, is associated with increased perioperative morbidity and is a risk factor for transfusion. There is evidence that patients who undergo transfusions have higher morbidity, increased cancer recurrence and poorer survival. The pathophysiology of anemia is multifactorial, with an inflammatory component to which chronic blood loss and nutritional deficiencies can be associated. Therefore, preoperative anemia in patients with cancer should be treated appropriately, given that there is sufficient time in the preoperative period. Of the currently available options, parenteral iron is an effective alternative, especially for those types of cancer that have an associated hemorrhagic component.

Abstract
In recent years, several safety alerts have questioned or restricted the use of some pharmacological alternatives to allogeneic blood transfusion in established indications. In contrast, there seems to be a promotion of other alternatives, based on blood products and/or antifibrinolytic drugs, which lack a solid scientific basis. The Multidisciplinary Autotransfusion Study Group and the Anemia Working Group España convened a multidisciplinary panel of 23 experts belonging to different healthcare areas in a forum for debate to: 1) analyze the different safety alerts referred to certain transfusion alternatives; 2) study the background leading to such alternatives, the evidence supporting them, and their consequences for everyday clinical practice, and 3) issue a weighted statement on the safety of each questioned transfusion alternative, according to its clinical use. The members of the forum maintained telematics contact for the exchange of information and the distribution of tasks, and a joint meeting was held where the conclusions on each of the items examined were presented and discussed. A first version of the document was drafted, and subjected to 4 rounds of review and updating until consensus was reached (unanimously in most cases). We present the final version of the document, approved by all panel members, and hope it will be useful for our colleagues.

Abstract
BACKGROUND The treatment of anemia in patients with cardiorenal syndrome (CRS) is based mainly on intravenous (IV) iron therapy and/or erythropoiesis-stimulating agents (ESAs). There are concerns about the safety of ESAs due to a potentially higher risk for stroke and malignancy. OBJECTIVE We aimed to explore whether IV iron alone is sufficient to improve anemia in CRS patients and to define the predictors of treatment response. METHODS We retrospectively analyzed data of 81 CRS patient treated for anemia at our clinic. All patients received IV iron for 6 weeks. A subset of patients was additionally given subcutaneous ESAs. The end point was the improvement from baseline in hemoglobin (Hb) and ferritin levels at week 7. RESULTS We retrieved the files of 81 patients; 34 received IV iron alone and 47 were given IV iron and ESAs (the combination group). The Hb levels significantly increased in both groups (in the IV iron alone group: 10.6 ± 1.1 to 11.9 ±1.1 g/dl, p < 0.001; in the combination group: 10.2 ± 0.9 to 12.4 ± 1.3 g/dl, p < 0.001), but more pronouncedly in the combination group (2.17 vs. 1.24 g/dl; p = 0.001). The platelet count decreased significantly in the IV iron alone group but was unchanged in the combination group. Eighty percent of patients attained a Hb target of 11 g/dl, with no significant difference between the two groups (73.5 vs. 85.1%; p = 0.197). Low baseline Hb was the only predictor of a favorable outcome to treatment. CONCLUSION Our observational study suggests that IV iron treatment without ESAs may substantially raise the Hb level to ≥11 g/dl in CRS patients. This treatment strategy may reduce the use of ESAs and hence its potential adverse effects.

Abstract
BACKGROUND Iron deficiency is associated with reactive thrombocytosis; however, the mechanisms driving this phenomenon remain unclear. We previously demonstrated that this occurs alongside enhanced megakaryopoiesis in iron-deficient rats, without alterations in the megakaryopoietic growth factors thrombopoietin, interleukin-6, or interleukin-11. OBJECTIVES The aim of this study was to evaluate megakaryocyte differentiation under iron deficiency in an in vitro model and to investigate potential genes involved in this process. METHODS Human erythroleukemia and megakaryoblastic leukemia cell lines, as well as cord-blood derived hematopoietic stem cells were cultured under iron deficiency. Cell morphology, ploidy, expression of CD41, CD61, and CD42b, and proplatelet formation were assessed in iron-deficient cultures. Polymerase chain reaction arrays were used to identify candidate genes that were verified using real-time polymerase chain reaction. Hypoxia-inducible factor 1, α subunit (HIF2α) protein expression was assessed in bone marrow sections from iron-deficient rats and vascular endothelial growth factor (VEGF)-A in culture supernatants. RESULTS AND CONCLUSIONS Iron deficiency enhanced megakaryoid features in cell lines, increasing ploidy and initiating formation of proplatelet-like structures. In cord blood cell cultures, iron deficiency increased the percentage of cells expressing megakaryopoietic markers and enhanced proplatelet formation. HIF2α and VEGF were identified as potential pathways involved in this process. HIF2α protein expression was increased in megakaryocytes from iron-deficient rats, and VEGF-A concentration was higher in iron-deficient culture supernatants. Addition of VEGF-A to cell cultures increased percentage expression of megakaryocyte CD41. In conclusion, the data demonstrate that iron deficiency augments megakaryocytic differentiation and proplatelet formation and a potential role of HIF2α in megakaryopoiesis.

Abstract
WHAT IS KNOWN AND OBJECTIVE In the management of anaemia associated with chronic kidney disease (CKD), optimal use of intravenous (i.v.) iron has a central role. It minimizes reliance on erythropoiesis-stimulating agents (ESAs) and may be beneficial in reducing overall cardiovascular risks through its effects on platelet counts (PLT). We have examined the effects of i.v. iron on PLT in patients with CKD. METHODS Two hundred and three patients with CKD, referred to a single teaching hospital in UK for i.v. iron therapy, received low molecular-weight iron dextran at a median dose of 1000 milligrams given over a median time of 2 h and 40 min. PLT at baseline were compared with the measurements taken during a 4-month follow-up period post-infusion. RESULTS PLT were checked at various points following i.v. iron treatment. Compared with baseline, mean reduction in PLT ranged between 10.1 and 23.6 (×10(9) /L) during consecutive 15-days intervals post-treatment. At the reference point of 90-days post-infusion, the drop in PLT was statistically significant (P < 0.001). WHAT IS NEW AND CONCLUSION Low molecular-weight iron dextran in patients with CKD leads to reduction in PLT. This reduction appears soon after treatment and is maximal after 3 months. Prospective data are required to confirm these findings and examine whether this translates to a reduction in thrombotic episodes.

Abstract
PURPOSE Use of erythropoiesis-stimulating agents (ESAs) in US cancer care declined amidst post-marketing evidence of adverse effects and the Food and Drug Administration's (FDA) addition of a "black-box" warning to product labeling in March 2007. Because reduced ESA use may have led to more transfusions or increased anemia-related health care needs, we measured the policy's impact on health care costs of lung and colon cancer patients receiving chemotherapy. METHODS In a retrospective cohort study of 13,630 lung and 3,198 colon cancer patients in the Department of Veterans Affairs (VA) between 2002 and 2008, we calculated anemia treatment (ESA and transfusion), cancer- and non-cancer-related, and total health care costs for the chemotherapy episode of care. We used multivariable regression to examine health care costs and utilization between patients whose chemotherapy was administered before (PRE) or after (POST) March 1, 2007. RESULTS ESA costs declined and transfusion costs were similar, resulting in lower overall POST-period anemia treatment costs (lung, $526 lower, P < 0.01; colon, $504 lower, P < 0.01). Other cancer-related health care costs increased, resulting in markedly higher POST-period total health care costs (lung, $4,706 higher, P < 0.01; colon, $11,414 higher, P < 0.01). CONCLUSIONS Although chemotherapy episode anemia treatment costs declined after the black-box warning, the savings were offset by increases in other cancer-related costs. Those increases were mainly in outpatient services and pharmacy, suggesting that likely drivers include adoption of new high-cost diagnostic approaches and therapeutic modalities. Additional research is needed to determine the effects of anemia management changes on patient outcomes and to more fully understand cost-benefit relationships in cancer treatment.

Abstract
Anemia, usually due to iron deficiency, is highly prevalent among patients with colorectal cancer. Inflammatory cytokines lead to iron restricted erythropoiesis further decreasing iron availability and impairing iron utilization. Preoperative anemia predicts for decreased survival. Allogeneic blood transfusion is widely used to correct anemia and is associated with poorer surgical outcomes, increased post-operative nosocomial infections, longer hospital stays, increased rates of cancer recurrence and perioperative venous thromboembolism. Infections are more likely to occur in those with low preoperative serum ferritin level compared to those with normal levels. A multidisciplinary, multimodal, individualized strategy, collectively termed Patient Blood Management, minimizes or eliminates allogeneic blood transfusion. This includes restrictive transfusion policy, thromboprophylaxis and anemia management to improve outcomes. Normalization of preoperative hemoglobin levels is a World Health Organization recommendation. Iron repletion should be routinely ordered when indicated. Oral iron is poorly tolerated with low adherence based on published evidence. Intravenous iron is safe and effective but is frequently avoided due to misinformation and misinterpretation concerning the incidence and clinical nature of minor infusion reactions. Serious adverse events with intravenous iron are extremely rare. Newer formulations allow complete replacement dosing in 15-60 min markedly facilitating care. Erythropoiesis stimulating agents may improve response rates. A multidisciplinary, multimodal, individualized strategy, collectively termed Patient Blood Management used to minimize or eliminate allogeneic blood transfusion is indicated to improve outcomes.

Abstract
Anemia is common in intensive care unit (ICU) patients. Red blood cell (RBC) transfusions are mainstays of their treatment and can be life-saving. Allogeneic blood components inherently bear risks of infection and immune reactions. Although these risks are rare in developed countries, recombinant human erythropoietin (rhEpo) and other erythropoiesis-stimulating agents (ESAs) have been considered alternative anti-anemia treatment options. As summarized herein, however, most of the clinical studies suggest that ESAs are not usually advisable in ICU patients unless approved indications exist (e.g., renal disease). First, ESAs act in a delayed way, inducing an increase in reticulocytes only after a lag of 3-4 days. Second, many critically ill patients present with ESA resistance as inflammatory mediators impair erythropoietic cell proliferation and iron availability. Third, the ESA doses used for treatment of ICU patients are very high. Fourth, ESAs are not legally approved for general use in ICU patients. Solely in distinct cases, such as Jehovah's Witnesses who refuse allogeneic blood transfusions due to religious beliefs, ESAs may be considered an exceptional therapy.

Abstract
Cancer patients are at increased risk of deep vein thrombosis and pulmonary embolism. The incidence among different groups of cancer patients varies considerably depending on clinical factors, the most important being tumor entity and stage. Biomarkers have been specifically investigated for their capacity of predicting venous thromboembolism (VTE) during the course of disease. Parameters of blood count analysis (elevated leukocyte and platelet count and decreased hemoglobin) have turned out to be useful in risk prediction. Associations between elevated levels and future VTE have been found for d-dimer, prothrombin fragment 1+2, and soluble P-selectin and also for clotting factor VIII and the thrombin generation potential. The results for tissue factor-bearing microparticles are heterogeneous: an association with occurrence of VTE in pancreatic cancer might be present, whereas in other cancer entities, such as glioblastoma, colorectal, or gastric carcinoma, this could not be confirmed. Risk assessment models were developed that include clinical and laboratory markers. In the high-risk categories, patient groups with up to a >20% VTE rate within 6 months can be identified. A further improvement in risk stratification would allow better identification of patients for primary VTE prevention using indirect or novel direct anticoagulants.

Abstract
Human erythropoietin (Epo) is a 30.4 kDa glycoprotein hormone composed of a single 165 amino acid residues chain to which four glycans are attached. The kidneys are the primary sources of Epo, its synthesis is controlled by hypoxia-inducible transcription factors (HIFs). Epo is an essential factor for the viability and proliferation of erythrocytic progenitors. Whether Epo exerts cytoprotection outside the bone marrow still needs to be clarified. Epo deficiency is the primary cause of the anemia in chronic kidney disease (CKD). Treatment with recombinant human Epo (rhEpo, epoetin) can be beneficial not only in CKD but also for other indications, primarily anemia in cancer patients receiving chemotherapy. Considering unwanted events, the administration of rhEpo or its analogs may increase the incidence of thromboembolism. The expiry of the patents for the original epoetins has initiated the production of similar biological medicinal products ('biosimilars'). Furthermore, analogs (darbepoetin alfa, methoxy PEG-epoetin beta) with prolonged survival in circulation have been developed ('biobetter'). New erythropoiesis-stimulating agents are in clinical trials. These include compounds that augment erythropoiesis directly (e.g. Epo mimetic peptides or activin A binding protein) and chemicals that act indirectly by stimulating endogenous Epo synthesis (HIF stabilizers).
