Preparing Hematology/Oncology Fellows for Success: Implementing an Annual Career Development and Research Retreat.

Multiple factors, including job satisfaction, personality traits, and training experiences, influence the career trajectory of hematology/oncology fellows. In an effort to expose hematology/oncology fellows to (1) the various careers in oncology, (2) a diverse group of speakers for future mentorship, and (3) research opportunities, and grant writing experience, we established an annual career development and research retreat. During the retreat, we engaged speakers who covered a range of career trajectories, including academic, private practice, industry, government, and administrative paths. We introduced clinicians and researchers with a track record of providing top-notch mentorship to fellows with aligning interests and detailed research opportunities and grant writing. The sessions were led by senior fellows, and we adopted an in-person and virtual hybrid model to allow speakers from various institutions to participate. Feedback from participants, as gathered through surveys, indicated positive responses: all respondents reported that this retreat was "extremely" or "very helpful," and a majority expressed their intent to pursue academic careers. The curriculum and structure of this retreat may help to inform the development of fellowship career development and research retreats at other institutions.

Postoperative venous thromboembolism and mortality in patients with pancreatic surgery.

BACKGROUND AND OBJECTIVES: Pancreatic cancer is strongly associated with thrombosis. We investigated early postoperative venous thromboembolism (PVTE) mortality among patients with pancreatic surgery and compared outcomes in adenocarcinoma pancreatic cancer (ACPC) to non-adenocarcinoma pancreatic neoplasm (NACPN). METHODS: We analyzed a prospectively collected database of patients who underwent pancreatic cancer or neoplasm-related surgery. As NACPN is underrepresented in other studies, we selected NACPN patients and a random sample of ACPC patients. PVTE was defined as VTE occurring within 3 months of surgical intervention. Statistical analysis was performed using Cox proportional hazards regression. RESULTS: A total of 441 pancreatic surgery patients were included, with 331 ACPC and 110 NACPN. Median follow-up was 449 days during which 90 (20.4%) patients developed VTE. PVTE occurred in 53 (12.0%) patients, including 41 (12.4%) ACPC patients and 12 (10.9%) NACPN patients. Those with PVTE had 60% higher mortality rate. A multivariable analysis found that PVTE is an independent predictor of increased mortality (HR Adj, 1.6; 95% CI, 1.1-2.2; P < .01). The mortality impact was not consistent between ACPC (HR, 3.2; 95% CI, 1.3-7.9) and NACPN groups (HR, 1.3; 95% CI, 0.9-1.8). CONCLUSIONS: Postoperative venous thromboembolism is an independent predictor of increased mortality in pancreatic surgery, specifically in adenocarcinoma pancreatic cancer surgery.

Rate and impact of venous thromboembolism in patients with ST-segment elevation myocardial infarction: Analysis of the Nationwide Inpatient Sample database 2003-2013.

Venous thromboembolism (VTE) and coronary artery disease are major health issues that cause substantial morbidity and mortality. New data have emerged suggesting that these two conditions could have a close relationship. Thus, we sought to determine the trends in annual rate of VTE occurrence in patients with ST-segment elevation myocardial infarction (STEMI) and measure its impact on in-hospital mortality, bleeding complications, and cost and length of hospitalization. We queried the 2003-2013 Nationwide Inpatient Sample databases to identify adults with primary diagnosis of STEMI. VTE events were then allocated. Inpatient outcomes of patients with VTE were compared to those without VTE. Out of 2,495,757 hospitalizations for STEMI, VTE was diagnosed in 25,149 (1%) hospitalizations. Patients who experienced VTE were older (mean age: 67.5 vs 64.8, p < 0.01) and had a higher proportion of black patients (10.1% vs 7.7%, p < 0.001) and females (40.1% vs 35%, p < 0.001) compared to patients without VTE. There was an increasing trend in the rate of VTE during the study period (2003: 0.8% vs 2013: 1.0%, p < 0.001). Patients with VTE had a prolonged hospitalization (median: 9 vs 3 days, p < 0.001), increased cost, higher risk of gastrointestinal bleeding (OR: 2.13, p < 0.001), intracranial hemorrhage (OR: 2.14, p < 0.001), blood transfusions (OR: 1.94, p < 0.001), and mortality (OR: 1.39, p < 0.001). The rate of VTE occurrence in patients with STEMI in our study was 10 per 1000 admissions. VTE was associated with more bleeding complications, longer hospital stays, higher costs, and mortality. These findings suggest that a more aggressive approach for VTE prophylaxis may be warranted in this population.

Primary Liver Diffuse Large B-Cell Lymphoma following Complete Response for Hepatitis C Infection after Direct Antiviral Therapy.

INTRODUCTION: Hepatitis C infection is highly prevalent worldwide and has a well-known association with B-cell lymphoid malignancies. Antiviral therapy has successfully decreased the rate of liver cirrhosis and improved the outcome in patients with hepatitis C-associated lymphomas. However, although there are a few case reports of aggressive lymphomas after successful hepatitis C therapy, the mechanism behind this association remains unclear. CASE PRESENTATION: We present the case of a 55-year-old man with chronic hepatitis C infection and liver cirrhosis who received antiviral therapy with sofosbuvir and ribavirin and achieved a sustained complete virological response. One year after successful therapy, there was an unexplained decline of his liver function and atypical liver nodularity, which led to the diagnosis of a primary liver diffuse large B-cell lymphoma. DISCUSSION: We review the evidence supporting possible mechanisms of lymphomagenesis after successful hepatitis C therapy, particularly involving late "second-hit" mutations after viral-induced DNA damage and antiviral therapy facilitating the emergence of latent malignant B-cell clones by decreasing local inflammation and immune surveillance. More reports may help elucidate any association between hepatitis C antiviral therapy and late lymphoid malignancies.

Evaluation of the prognostic value of neutrophil to lymphocyte ratio in patients with hypertriglyceridemia-induced acute pancreatitis.

INTRODUCTION: Recent studies attribute promising prognostic values to various inflammatory biomarkers in acute pancreatitis, including the following: the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and red cell distribution width (RDW). We aimed to determine the performance of these biomarkers for detecting disease severity in patients with hypertriglyceridemia-induced acute pancreatitis (HTG-AP). METHODS: We retrospectively reviewed 110 patients with HTG-AP and compared the NLR, PLR, and RDW in different severity groups. We performed receiver-operating characteristic (ROC) analysis to identify the optimal cut-off value for NLR to predict severe AP. RESULTS: NLR was significantly higher in patients with severe AP than mild and moderately severe AP (14.6 vs. 6.9, p < 0.001), and higher with organ failure upon presentation (9.1 vs. 7.1, p = 0.026). After dichotomization by the optimal cut-off value of 10 as determined by the ROC curve, the high-NLR group had a significantly longer length of stay (9.1 vs. 6.6 days, p = 0.001), duration of nil per os (4.9 vs. 3.7 days, p = 0.007), and higher rates of complications, including systemic inflammatory response syndrome (81.5% vs. 44.6%, p = 0.001) and persistent acute kidney injury (25.9% vs. 3.6%, p < 0.001). High NLR independently predicted severe acute pancreatitis in multivariate analysis (Odds ratio 6.71, p = 0.019). CONCLUSION: NLR represents an inexpensive, readily available test with a promising value to predict disease severity in HTG-AP. Among the three inflammatory biomarkers, NLR has the highest discriminatory capacity for severe HTG-AP, with an optimal cut-off value of 10.

Comparative Effectiveness of Anticoagulants in Patients With Cancer-Associated Thrombosis.

Importance: Patterns of clinical utilization and comparative effectiveness of anticoagulants for cancer-associated thrombosis (CAT) remain largely unexplored. Objectives: To assess patterns of and factors associated with anticoagulant use and to evaluate the comparative effectiveness of contemporary anticoagulants in patients with active cancer in a clinical setting. Design, Setting, and Participants: This retrospective cohort study obtained deidentified OptumLabs electronic health record claims data from January 1, 2012, to September 30, 2019. Adult patients (≥18 years of age) with a primary cancer diagnosis (except skin cancer) during at least 1 inpatient or 2 outpatient visits within 6 months before the venous thromboembolism (VTE) date were included. Data were analyzed from April 2020 to September 2021. Exposures: The patients were grouped according to the anticoagulant prescribed: (1) direct oral anticoagulants (DOACs), (2) low-molecular-weight heparin (LMWH), and (3) warfarin. Main Outcomes and Measures: Odds ratios (ORs) were used to present the association between factors of interest and utilization of anticoagulants. Main efficacy outcomes included risk of VTE recurrence and all-cause mortality. Main safety outcomes included the risk of hospitalization due to major bleeding. Relative treatment effect estimates were expressed as hazard ratios (HRs) with 95% CIs. Results: This study included 5100 patients (mean [SD] age, 66.3 [12.3] years; 2670 [52.4%] women; 799 [15.7%] Black, 389 [7.6%] Hispanic, and 3559 [69.8%] White individuals). Overall, 2512 (49.3%), 1488 (29.2%), and 1460 (28.6%) filled prescriptions for DOACs, LMWH, and warfarin, respectively. The median (IQR) treatment duration was 3.2 (1.0-6.5) months for DOACs, 3.1 (1.0-6.8) months for warfarin, and 1.8 (0.9-3.8) months for LWMH. Patients with lung (OR, 2.07; 95% CI, 1.12-3.65), urological (OR, 1.94; 95% CI,1.08-3.49), gynecological (OR, 4.25; 95% CI, 2.31-7.82), and colorectal (OR, 2.26; 95% CI, 1.20-4.32) cancer were associated with increased prescriptions for LMWH compared with DOACs. LMWH (HR, 1.47; 95% CI, 1.14-1.90) and warfarin (HR, 1.46; 95% CI, 1.13-1.87) were associated with an increased risk of VTE recurrences compared with DOACs. LMWH was associated with an increased risk of major bleeding (HR, 2.27; 95% CI, 1.62-3.20) and higher all-cause mortality (HR, 1.61; 95% CI, 1.15-2.25) compared with DOACs. Conclusions and Relevance: In this comparative effectiveness study of claims-based data, patients with CAT received anticoagulation for a remarkably short duration in clinical settings. DOACs was associated with a lower risk of VTE recurrence, major bleeding, and mortality. Warfarin may still be considered for patients with contraindications to DOACs and those with poor persistence on LMWH.

Direct Oral Anticoagulants Compared With Dalteparin for Treatment of Cancer-Associated Thrombosis: A Living, Interactive Systematic Review and Network Meta-analysis.

OBJECTIVE: To maintain living, interactive evidence (LIvE) on the benefits and harms of different treatment options in adults with cancer-associated thrombosis (CAT). METHODS: We have used a novel LIvE synthesis framework to maintain this living, interactive systematic review since September 19, 2018. Randomized controlled trials evaluating the efficacy and safety of direct oral anticoagulants (DOACs) compared with low-molecular-weight heparin for CAT are included in this analysis. Details of LIvE synthesis framework are available at the website https://cat.network-meta-analysis.com. RESULTS: The results are constantly updated as new information becomes available (https://cat.network-meta-analysis.com/CAT.html). The living, interactive systematic review currently includes 4 randomized controlled trials (N=2894). Direct comparisons show that DOACs significantly decrease recurrent venous thromboembolism (VTE) events compared with dalteparin (odds ratio [OR], 0.59; 95% CI, 0.41 to 0.86; I2, 25%) without significantly increasing major bleeding (OR, 1.34; 95% CI, 0.83 to 2.18; I2, 28%). Mixed treatment comparisons show that apixaban (OR, 0.41; 95% credible interval [CrI], 0.16 to 0.95) and rivaroxaban (OR, 0.58; 95% CrI, 0.37 to 0.90) significantly decrease VTE recurrent events compared with dalteparin. Edoxaban significantly increases major bleeding compared with dalteparin (OR, 1.73; 95% CrI, 1.04 to 3.16), and rivaroxaban significantly increases clinically relevant nonmajor bleeding compared with dalteparin and other DOACs. There are no significant differences between DOACs in terms of VTE recurrences and major bleeding. CONCLUSION: DOACs should be considered a standard of care for the treatment of CAT except in patients with a high risk of bleeding. Current evidence favors the use of apixaban for the treatment of CAT among other DOACs. REGISTRATION: Open Science Framework (https://osf.io/dth86).

Trends and Inpatient Outcomes of Venous Thromboembolism-Related Admissions in Patients with Philadelphia-Negative Myeloproliferative Neoplasms.

Background Patients with Philadelphia-negative myeloproliferative neoplasms (MPNs), including polycythemia vera (PV), essential thrombocytosis (ET), and primary myelofibrosis (MF), have a significant risk of venous thromboembolism (VTE). We aim to determine the trends in annual rates of VTE-related admissions, associated cost, length of stay (LOS), and in-hospital mortality in patients with MPN. Methods We identified patients with PV, ET, and MF from the Nationwide Inpatient Sample (NIS) database from 2006 to 2014 using ICD-9CM coding. Hospitalizations where VTE was among the top-three diagnoses were considered VTE-related. We compared in-hospital outcomes between VTE and non-VTE hospitalizations using chi-square and Mann-Whitney U -test and used linear regression for trend analysis. Results We identified 1,046,666 admissions with a diagnosis of MPN. Patients were predominantly white (65.6%), females (52.7%), with a median age of 66 years (range: 18-108). The predominant MPN was ET (54%). There was no difference in in-hospital mortality between groups (VTE: 3.4% vs. non-VTE: 3.2%; p = 0.12); however, VTE admissions had a longer LOS (median: 6 vs. 5 days; p < 0.01) and higher cost (median: VTE US$32,239 vs. 28,403; p ≤ 0.01). The annual rate of VTE admissions decreased over time (2006: 3.94% vs. 2014: 2.43%; p ≤ 0.01), compared with non-VTE-related admissions. Conclusion In our study, VTE-related admissions had similar in-hospital mortality as compared with non-VTE-related admissions. The rates of hospitalizations due to VTE have decreased over time but are associated with a higher cost and LOS. Newer risk assessment tools may assist in preventing VTE in high-risk patients and optimizing resource utilization.

Gaps of care in patients with venous thrombotic embolism: a qualitative study.

BACKGROUND: Venous thromboembolism (VTE) includes pulmonary embolism (PE) and deep vein thrombosis (DVT), and results in 100,000 deaths annually in the United States. There is low global VTE awareness, including limited data regarding difficulties patients encounter during their management. This study aims to identify a patient's perspective on VTE gaps of care. METHODS: This is a qualitative study using semi-structured interviews with VTE patients, who had been previously diagnosed and treated for at least one VTE event in their lifetime. Participants were separated in five focused groups; sample size was defined by data saturation. Interviews were audio recorded, transcribed verbatim, and analyzed thematically using framework analysis based on data saturation evaluation. The study was approved by a local institutional review board. We used inductive framework analysis to interpret the data. RESULTS: Twenty participants were included in the analysis. Ten participants (50%) were men. Three major themes were identified: 1) concerned about limited disease knowledge; 2) VTE awareness in healthcare system; 3) incomplete communication during transitional and follow-up care. CONCLUSIONS: Findings suggest that gaps of VTE care extend in different levels of the medical system, including: the patient, physicians, and medical teams. Patients were sensitive to a lack of disease awareness among healthcare providers. There was appreciation for subspecialty care recommended for VTE. In a qualitative study, using the patient perspective, we have detected frustrations and perceived areas of improvement of the care of the patient with VTE. These gaps are anchored in perceived lack of disease awareness and difficult transitional care.

Direct Oral Factor Xa Inhibitors for the Treatment of Acute Cancer-Associated Venous Thromboembolism: A Systematic Review and Network Meta-analysis.

OBJECTIVE: To explore the efficacy and safety of direct oral factor Xa inhibitors in the treatment of cancer-associated acute venous thromboembolism (VTE). PATIENTS AND METHODS: MEDLINE, CENTRAL (Cochrane Central Register of Controlled Trials), and Embase databases were searched for trials comparing direct oral anticoagulants (DOACs) to dalteparin for the management of cancer-associated acute VTE. Databases were searched from inception to September 19, 2018. A network meta-analysis using both frequentist and Bayesian methods was performed to analyze VTE recurrence and major and clinically relevant nonmajor bleeding. RESULTS: We identified 3 randomized controlled trials, at low risk of bias, that enrolled 1739 patients with cancer-associated VTE. Direct comparison revealed a lower rate of VTE recurrence in DOAC compared with dalteparin groups (odds ratio [OR], 0.48; 95% CI, 0.24-0.96; I2=46%). Indirect comparison suggested that apixaban had greater reduction in VTE recurrence compared with dalteparin (OR, 0.10; 95% CI, 0.01-0.82) but not rivaroxaban or edoxaban. Apixaban also had the highest probability of being ranked most effective. By direct comparisons, there was an increased likelihood of major bleeding in the DOAC group compared with dalteparin (OR, 1.70; 95% CI, 1.04-2.78). Clinically relevant nonmajor bleeding did not differ. Indirect estimates were imprecise. Subgroup analyses in gastrointestinal cancers suggested that dalteparin may have the lowest risk of bleeding, whereas estimates in urothelial cancer were imprecise. CONCLUSION: Direct oral anticoagulants appear to lower the risk of VTE recurrence compared with dalteparin while increasing major bleeding. Apixaban may be associated with the lowest risk of VTE recurrence compared with the other DOACs.

Intermittent pneumatic compression in patients with ESRD. A systematic review.

INTRODUCTION: Patients with end-stage renal disease (ESRD) experience frequent hemodialysis (HD) complications. Intradialytic hypotension (IDH) is a common complication presenting in approximately between 20 and 50% of HD sessions. Available interventions such as volume replacement or vasoactive medications are associated with significant side effects. Intermittent pneumatic compression (IPC) has been proposed as a feasible intervention for the prevention of IDH, treatment of peripheral arterial disease and venous ulcers. These devices apply intermittent pressure to the legs improving arterial blood flow, mobilization of pooled blood with an increase in venous return increasing the effective circulatory volume. Our goal was to identify the published clinical evidence on whether IPC has a circulatory benefit and is it well-tolerated among patients receiving HD. METHODS: We conducted a systematic review to identify studies assessing the efficacy and safety of IPC in patients with ESRD. Our primary outcome was IDH. Secondary outcomes such as HD comfort, ultrafiltration volume, and physical activity were collected. No restrictions where used and we included all observational and interventional studies. Two reviewers performed screening and study quality assessment. FINDINGS: We included seven studies. Out of the seven studies, five addressed IDH, and the rest were included for secondary outcomes such as physical capacity and HD comfort. In one randomized crossover trial comparing exercise against IPC, 21 patients were randomized to 3 different arms (no intervention, cycling, IPC) a decrease in the rates of IDH with IPC was described (43%, 38%, and 24% respectively P = 0.014). The smaller studies corroborated these results. All studies where at high risk of bias. DISCUSSION: IPC might offer significant benefits for patients undergoing HD not limited to prevention of IDH but also improvement of hemodialysis comfort and physical capacity. However, our results should be interpreted in the context of its limitations.

Pancreatic cancer thromboembolic outcomes: rate of thrombosis after adenocarcinoma and non-adenocarcinoma pancreatic cancer surgery.

BACKGROUND: The aim of this study was to define the association of non-adenocarcinoma pancreatic cancer (NACPC) as a risk factor for postoperative cancer-associated thrombosis (CAT). METHODS: We conducted analysis of prospectively collected data of pancreatic cancer surgery. Randomly collected NACPC cases were matched 1:3 to adenocarcinoma cases (ACPC). Variables included comorbidities, demographics, cancer extension, and preoperative Khorana score (KRS). Primary outcome was CAT, which included deep vein thrombosis and pulmonary embolism confirmed by imaging. Categorical variables are presented as percentages, continuous variables as median and range. SPSS, χ2, Cochran-Armitage, and logistic regression were use for analysis. RESULTS: The study included 441 patients. Age 65.9±11.5, male 57% (N.=252), 8% (N.=36) had metastasis. IPMN and neuroendocrine were the most common NACPC. Median follow-up was 449 days in which 90 (20%) patients developed CAT. The odds (Odds Ratio [OR] 1.1, 95% Confidence Interval [CI] 0.6- 1.9, P=0.7) and time to venous thromboembolism were not different between NACPC and ACPC. We analyzed for trends of prophylactic strategies by year of surgery; there was no trend for NACPC (P=0.4) or ACPC (P=0.06). KRS was not associated with CAT. In the multivariate analysis, peripheral artery disease (Adjusted Odds Ratio [ORadj] 5.4, 95% CI: 1.7-17.3), ASA class ≥4 (ORadj 3.6; 95% CI: 1.3-10.4), length of stay >9 days (ORadj: 1.9; 1.2-3.2), and cancer vascular invasion (ORadj: 2.9; 95% CI: 1.6-5.3) were associated with CAT. CONCLUSIONS: The rate of VTE in NACPC after surgery was high and not different than ACPC. Histology type should not govern discrimination in thromboprophylaxis selection or extension.

Prediction of early mortality in patients with cancer-associated thrombosis in the RIETE Database.

BACKGROUND: Proper risk stratification of patients for early mortality after cancer-associated thrombosis may lead to personalized anticoagulation protocols. Therefore, we aimed to derive and validate a scoring system to predict early mortality in this population. To this end, we selected patients with active cancer and thrombosis from the Computerized Registry of Patients with Venous Thromboembolism database. METHODS: The main outcome was all cause mortality within the month following a thrombotic event. We used a simple random selection to split are data in a derivation and a validation cohort. In the derivation cohort, we used recursive partitioning and binary logistic regression to identify groups at risk and to determine the likelihood of the primary outcome. The risk score was developed based on odds ratios from the final multivariate model, and then tested in the validation cohort. RESULTS: In 10,025 eligible patients, we identified 6 predictors of 30-day mortality: leukocytosis ≥11.5x109/L; platelet count ≤160x109/L, metastasis, recent immobility, initial presentation as pulmonary embolism and Body Mass Index <18.5. The model divided the population into 3 risk categories: low (score 0-3), moderate (score 4-6), and high (score ≥7). The AUC for the overall score was 0.74, and using a cutoff ≥7 points, the model had a negative predictive value of 94.4%, a positive predictive value of 23.1%, a sensitivity of 73.3%, and a specificity of 64.6% in the validation cohort. CONCLUSIONS: Our validated risk model may assist physicians in the selection of patients for outpatient management, and perhaps anticoagulant, considering expanding anticoagulation options.

Evaluating Unconscious Bias: Speaker Introductions at an International Oncology Conference.

PURPOSE: In a professional setting, the introduction of female speakers without their professional title may have an impact on the public's perception of the female speaker. We examined how professional titles were used during speakers' introductions at the ASCO Annual Meeting. METHODS: We conducted a retrospective, observational study of video-archived speaker introductions at the 2017 and 2018 ASCO Annual Meetings. A "professional address" was defined as the professional title followed by the speaker's full name or last name. Multivariable logistic regressions were used to identify factors associated with the form of address. RESULTS: Of 2,511 videos reviewed, 781 met inclusion criteria. Female speakers were addressed less often by their professional title compared with male speakers (62% v 81%; P < .001). Males were less likely to use a professional address when introducing female speakers compared with females when introducing male speakers (53% v 80%; P < .01). When women performed speaker introductions, no gender differences in professional address were observed (75% v 82%; P = .13). Female speakers were more likely to be introduced by first name only (17% v 3%; P < .001). Male introducers were more likely to address female speakers by first name only compared with female introducers (24% v 7%; P < .01). In a multivariable regression including gender, degree, academic rank, and geographic location of the speaker's institution, male speakers were more likely to receive a professional address compared with female speakers (odds ratio, 2.43; 95% CI, 1.71 to 3.47; P < .01). CONCLUSION: When introduced by men, female speakers were less likely to receive a professional address and more likely to be introduced by first name only compared with their male peers.

Risk assessment as a guide for the prevention of cancer-associated thromboembolism.

Venous thromboembolism (VTE) is a major source of morbidity and mortality among patients diagnosed with cancer. In addition to an increased risk of VTE, patients with cancer are at higher risk of bleeding while receiving therapeutic anticoagulation. Aggressive and targeted thromboprophylaxis is a crucial practice to avoid the dreaded complications of VTE. Risk assessment models (RAM) are tools developed to identify high-risk patients in whom thromboprophylaxis is beneficial. This review describes the most validated VTE RAMs in patients with cancer.

Performance of Current Thromboembolism Risk Assessment Tools in Patients With Gastric Cancer and Validity After First Treatment.

Patients with gastric cancer (GC) are at higher risk of thromboembolism when compared to other solid tumors. We aim to determine the predictive performance of current venous thromboembolism (VTE) predictive tools and their variability and validity after first treatment. Single institution cohort of GC-treated patients (2010*15). We abstracted predictive tools, validated for VTE prediction in patient with cancer; including the Khorana Score (KRS), platelet to lymphocyte ratio (PLR), and neutrophil to lymphocyte ratio (NLR). The primary outcome was CAT prediction. We included 112 patients who were predominantly men (66%), 58 (51-64)-year-olds, with adenocarcinoma (84%) and advanced disease (59%). The median follow-up was 21.3 months (9.5-42.6). The VTE occurrence was 12%. The median time from diagnosis to VTE occurrence was 59 days (36-258). In our cohort, performance status (PS; hazard ratio [HR], 8.02; 95% confidence interval [CI], 2.37-27.14; P < .01) was an independent predictor of VTE whereas KRS (univariate HR, 2.3; 95% CI, 0.7-7.4; P = .17), PLR (univariate HR, 0.8; 95% CI, 0.2-3.1; P = .8), and NLR (univariate HR, 0.8; 95% CI, 0.3-2.5; P = .8) at baseline were not associated with VTE risk. The posttreatment KRS was an independent predictor of VTE (HR, 3.69; 95% CI, 1.17-11.65; P = .25) along with PS (HR, 7.58; 95% CI, 2.27-25.33; P = .01). Posttreatment KRS appears as a valid tool to identify patients with GC at high risk of VTE after first cancer treatment.

Venous Thromboembolism Is an Independent Predictor of Mortality Among Patients with Gastric Cancer.

BACKGROUND: Venous thromboembolism (VTE) is an independent predictor of death among patients with cancer. Patients with gastric cancer (GC) are at higher risk for VTE when compared to other solid tumors, and if one considers its prevalence, GC may be responsible for one of the highest incidences of cancer-associated thrombosis. The impact of VTE on mortality is not well defined among patients with GC. AIM: The aim of this study is to measure the impact of VTE as independent predictor of GC mortality. METHODS: Chart review of patients with GC treated in the Department of Oncology at John Stroger Hospital between the years of 2010 and 2015. VTE events were objectively confirmed with imaging in all cases. Active GC was defined as biopsy-proven metastatic disease or on active chemotherapy. Along with cancer-specific data, we abstracted risk assessments tools, non-GC-specific, validated for VTE and mortality prediction cancer, including the Khorana score (KRS), platelet lymphocyte ratio (PLR), and neutrophil lymphocyte ratio (NLR). Continuous variables are expressed by the median as appropriate according to normality. Categorical variables are expressed as percentages. SPSS version 22 was used and chi-square, Mann-Whitney U, Kaplan-Meier curve, and Cox proportional hazard with forward modeling were applied. RESULTS: We included 112 patients in the analysis. The patients were predominantly men (66%), 58-year-old, with adenocarcinoma (84%) and advanced disease (59%). The median follow-up was 21.3 months (IQR 8.9-42.4). Cumulative incidence of VTE at 1 year was 9%. The median time from diagnosis to VTE occurrence was 59 days (IQR 36 to 258). Patients with VTE had worse OS when compared to the non-VTE group (medians 11.87 vs 29.97 months, p = 0.02). Patients stratified as high risk by the PLR had worse OS (medians 22.6 vs 42.77 months, p = 0.02). There was no statistical difference in OS among patients stratified as high risk by the KRS (medians 23.7 vs 42.5, p = 0.16) and NLR (medians 24.1 vs 42.7 months, p = 0.21). In multivariate analysis, the independent predictors of mortality were VTE (hazard ratio (HR), 2.9; 95% CI, 1.4 to 6.6; p < 0.01), adenocarcinoma (HR, 3.1; 95% CI, 1.1 to 9.0; p = 0.03), advanced disease (HR, 2.8; 95% CI, 1.4 to 5.8; p < 0.01), and PLR (HR, 2.2; 95% CI, 1.3 to 3.8; p < 0.01). CONCLUSION: VTE is associated with worse survival among patients with GC along with adenocarcinoma, advanced disease, and PLR. Moreover, these findings were independent of other cancer- and treatment-specific variables. Although potentially predictive in other cancer types, NLR and KRS were not associated with worse survival in this cohort.

Predictors of Early Mortality in Cancer-Associated Thrombosis: Analysis of the RIETE Database.

Cancer-associated thrombosis (CT) carries a high, heterogeneous, and poorly predicted likelihood of mortality. Thus, we aimed to define predictors of 30-day mortality in 10,025 patients with CT. In a randomly selected derivation cohort, we used recursive partitioning analysis to detect variables that select for a risk of mortality within 30 days. In a validation cohort, we evaluated our results using Cochran-Armitage test. The most common types of cancer were lung (16%), breast (14%), and colorectal (14%); median age was 69 years (range, 14-101); most had metastatic disease (63%); 13% of patients died within 30 days. In the derivation cohort ( n = 6,660), a white blood cell (WBC) count in the highest quartile predicted early mortality (odds ratio, 7.8; 95% confidence interval [CI], 4.6-13.1); and the presence of metastatic disease, pulmonary embolism (PE), and immobility defined the risk of those with normal WBC count. We defined death risk according four sequential questions: (1) Does the patient have an elevated WBC count? (Yes, group D). (2) If no, does the patient have metastasis? (No, group A). (3) If yes, is the patient immobile? (Yes, group D). (4) If no, does the patient have a PE? (Yes, group C; no, group B). In the validation cohort ( n = 3,365), the 30-day risk of death was 2.9% in group A (95% CI, 1.9-4.3), compared with 25% in group D (95% CI, 22.5-27.5), and there was a rate escalation between groups ( p for trend < 0.01). In conclusion, with four sequential questions, the risk of death in CT can be easily stratified. An elevated WBC count at baseline predicted 30-day mortality better than metastases, PE, or immobility.

Validation of a Patient-Completed Caprini Risk Assessment Tool for Spanish, Arabic, and Polish Speakers.

Targeted prophylaxis for venous thromboembolism (VTE) using the Caprini risk score (CRS) is effective reducing postoperative VTE. Despite its availability as preventive strategy, risk scoring remains underutilized. Critics to the CRS contend the time it takes to complete, and its limitation to English language. Aim is to create and validate patient-completed CRS tools for Spanish, Arabic, and Polish speakers. We translated the first patient-completed CRS to Spanish, Arabic, and Polish. We conducted a pilot study followed by the validation study. Using PASS version 11, we determined that a sample size of 37 achieved a power of 80%, to detect a difference of 0.1 between the null hypothesis correlation of 0.5 and the alternative hypothesis correlation of 0.7 using a 2-sided hypothesis test, significance level of .05. We tabulated and categorized scores using SPSS version 23 to estimate κ, linear correlation, and Bland Altman test. κ value >0.8 was defined as "almost perfect agreement." From 129 recruited patients, 50 (39%) spoke Spanish, 40 (31%) spoke Arabic, and 39 (30%) spoke Polish; average age 51 (16.69) years, 58 (45%) were men, with less than college education (67%). Mean (standard deviation) CRS was 5 (3.90), the majority (63%) above moderate VTE risk. We report excellent agreement comparing physician and patient results (κ = 0.93) and high correlation 0.97 ( P < .01) for the overall score. Bland Altman did not show trend for extreme values. We created and validated the first Spanish, Arabic, and Polish versions of the patient-completed CRS, with excellent correlation and agreement when compared to CRS-trained physician-completed form. Based on these results, the physician needs to calculate the body mass index. Completing the form was not time-consuming.
