Introduction: The occurrence of venous thromboembolism (VTE) during chemotherapy may result in treatment delays with unfavorable effects on cancer outcome, therefore VTE prevention is a relevant issue. Current guidelines recommend primary thromboprophylaxis in select high-risk cancer outpatients undergoing chemotherapy. Hence, the use of risk assessment models involving both clinical and biological parameters is increasingly important. In this analysis, in a large prospective cohort of patients with newly diagnosed metastatic non-small cell lung (NSCLC), colorectal (CRC), gastric (GC) or breast (BC) cancers, we assessed whether pre-chemotherapy levels of thrombotic biomarkers may help to stratify patients at different risk levels of VTE during the first 6 months of anti-tumor therapy. Methods: The study cohort included patients with advanced cancer enrolled from January 2012 to December 2017 in the HYPERCAN study (ClinicalTrials.gov, ID# NCT02622815), an ongoing Italian prospective, multicenter, observational study (Falanga et al, Thromb Res 2016). Clinical data and blood samples were collected at enrollment and during scheduled follow-up visits. Baseline plasma levels of fibrinogen (Clauss method), d-dimer (immunoturbidimetric assay), prothrombin fragment F1+2 (ELISA), FVIIa-AT (ELISA) and thrombin generation (TG, CAT assay) were measured. The study protocol was approved by the local Ethics Committee. Informed written consent was obtained from all study subjects. The outcome measure of the current analysis is the time to the occurrence of first symptomatic and/or incidental VTE, objectively confirmed. Results: A cohort of 922 patients [median age: 66 (30-92) years] with metastatic NSCLC (n=416), CRC (n=262), GC (n=105) and BC (n=139) was available for analysis. After a median follow-up of 327 days (range 44-1,548), VTE occurred in 122 (76 M/46 F) patients [median age 64 y (range 40-85)] providing a cumulative incidence of 19.7% (CI 95%: 16-23). According to tumor site, VTE frequency was: NSCLC (n= 64, 15.3%) > CRC (n= 38, 14.5%) > GC (n= 12, 11.4%) > BC (n= 8, 5.7%). Biomarkers' analysis of baseline plasma samples from 598 patients showed significantly higher levels of fibrinogen, d-dimer and TG in the cancer cohort compared to healthy control subjects (p<0.01). NSCLC patients had significantly (p<0.001) higher levels of d-dimer compared to CRC and BC patients, and of fibrinogen (p<0.001) compared to CRC, BC and GC patients. Cumulative incidence of VTE at 6 months was 10% (CI 95% 8-12). In particular, patients who had VTE in 6 months presented with significantly higher pre-chemotherapy levels of D-Dimer than VTE-free subjects (p<0.05). Cox-multivariate analysis identified as independent risk factors for VTE, high d-dimer (HR: 2.1, CI 95% 1.2 - 3.7; p=0.008), high peak of TG (HR: 1.8, CI 95% 0.99 - 3.2; p=0.052), and site of primary tumor (non-BC vs BC) (HR: 3.3, CI 95% 1.01 - 10.5; p=0.048). A score for VTE prediction was created with these variables and three risk categories (low, intermediate, and high) were generated. The cumulative incidence of VTE at 6 months in each risk category was 3.9%, 9.8%, and 19%, respectively (low vs high HR: 2.36 p=0.005; intermediate vs high HR 2.16 p=0.006). Differently, the application of the Khorana score failed to identify high risk patients. Conclusions: Our prospective study in a large cohort of metastatic cancer patients shows the high burden of VTE during the first 6 months of chemotherapy. Furthermore, laboratory data from this analysis enable us to create a risk scoring system based on d-dimer and TG together with tumor site, that significantly identifies patients at the highest VTE risk. Further investigation are worth to externally validate this score for clinical use.

Abstract Introduction: Atrial fibrillation (AF) is not uncommon in cancer patients with grade 3-4 thrombocytopenia (platelets <50x10 9/L). The risk of bleeding appears to outweigh the risk of thrombosis in acute leukemia patients. There are no published data regarding management of anticoagulation (AC) and rates of bleeding and thrombosis in other cancer types. Aim: To assess AC management and incidence of bleeding and thrombosis in thrombocytopenic cancer patients with AF. Methods: Single-center retrospective cohort study. The study included adults with active cancer, grade 3-4 thrombocytopenia (platelets <50x10 9/L) and AF with CHA 2DS 2-VASc ≥1, irrespective of AC status prior index. Patients with acute leukemia were excluded. Patients were indexed when platelets <50x10 9/L. AC management was classified as either "No-AC", if AC was withheld (i.e., stopped or not started) at index, or "Continue-AC", if AC was continued. Arterial thromboembolism (ATE; ischemic stroke, transient ischemic attack or systemic embolism) and ISTH-defined major bleeding were recorded over 30 days. The 30-day cumulative incidence of composite and individual outcomes with corresponding 95% confidence intervals (CI) was calculated for each management group (death as competing risk). A Cox proportional hazards model was used to calculate hazard ratios (HR) and corresponding 95% CI for outcomes between the No-AC and Continue-AC groups, with death as a competing risk (Fine and Gray model). Results: The eligibility criteria were met by 131 patients. At study index, AC was not given in 90 (69%) patients and continued in 41 (31%). Table 1 shows patient characteristics overall and stratified for management. The median age was 80 years )IQR 70-82) and 55 (42%) were females. Most patients were inpatients at index (70%) and had newly diagnosed cancer (70%). 64% had solid malignancy, and the remainder had hematological malignancy. The majority (92%) had AF prior to study index, while 8% had AF newly diagnosed at index. The median CHA 2DS 2-VASc score was 4 [IQR 3-5] and 18% had a prior stroke. Median platelet counts were 42 x 10 9/L at index and the median HASBLED score was 5 [3-5]. Only 44% of the No-AC group were receiving AC prior index, compared with 95% in the Continue-AC group, at shorter median duration. The type of prior AC differed between groups. Antiplatelet therapy (54%) and major bleeding prior index (13%) were more frequent in the No-AC group. There was a median [IQR] of 4 [0-60] and 4 [1-26] days of grade 3-4 thrombocytopenia in the No-AC and Continue-AC groups, respectively. Platelet nadirs (x10 9/L) were numerically higher in the No-AC group (31 [3-50] vs. 21 [6-50]; p=0.09). A median [IQR] of 12 [6-17.25] and 10 [5-12] platelet transfusions were given to 29 (32.2%) patients in the No-AC group and 11 (26.8%) in the Continue-AC group, respectively (p>0.2). In the Continue-AC group, AC was subsequently held in 12/41 (29%) and dose-reduced in 4/41 (10%) during the 30 days post-index. The 30-day cumulative incidence [95% CI] of the composite outcome (major bleeding or ATE) was 10% [4.88-17.27] in the No-AC group and 4.88% [0.86-14.7] in the Continue-AC group (HR 2.142 [0.47-9.609]). The 30-day cumulative incidence of ATE (Figure 1A) was 3.33% [0.88-8.66] in the No-AC group (n=3), and 4.88% [0.85-14.7] in the Continue-AC group (n=2), corresponding with a HR of 0.70 [0.12-4.10]. The 30-day cumulative incidence of major bleeding (Figure 1B) was 7.8% [3.40-14.52] in the No-AC group, and 2.44% [0.18-11.22] in the Continue-AC group (HR 3.29 [0.42-26.04]). The 30-day overall survival was 64.4% in the No-AC and 73.2% in the Continue-AC groups (HR 1.39 (95% CI 0.7-2.76). Conclusions: In a cohort of cancer patients with grade 3-4 thrombocytopenia (<50x10 9/L) and AF (median CHA 2DS 2-VASc = 4), the majority had anticoagulation held. Baseline thrombotic and bleeding risk factors were generally balanced, but a higher rate of prior bleeding and lower rates of anticoagulation prior index in the No-AC group, suggest confounding by indication. No statistically significant difference in outcomes was detected between management groups, but 95% CI's were wide. The high bleeding and low ATE incidence in the No-AC group suggests that holding AC during time-limited periods of grade 3-4 thrombocytopenia may be a reasonable approach in many cancer patients with AF. Continuing AC should be investigated in a subset of patients with lower bleeding and higher thrombotic risk. Figure 1 Figure 1.

Background. Hypercoagulability, a common finding in cancer patients, is associated with an increased risk of both thrombosis and tumor development. The HYPERCAN study (ClinicalTrials.gov, ID# NCT02622815) is an ongoing Italian prospective, multicenter, observational study, evaluating the predictive value of thrombotic markers for early cancer diagnosis in healthy subjects and for cancer prognosis and venous thromboembolism in patients with newly diagnosed malignant disease. In this analysis of a large cohort of patients with breast cancer, we evaluated whether pre-chemotherapy thrombotic biomarker levels: 1. are associated with breast cancer-specific clinicopathological features; and 2. may predict for disease recurrence (DR). Patients and Methods. D-dimer, fibrinogen, prothrombin fragment 1+2 (F1+2), and FVIIa/antithrombin complex (FVIIa/AT) levels were measured in 701 early-stage resected breast cancer patients, candidate to adjuvant chemotherapy and prospectively enrolled in the HYPERCAN study. Significant prognostic parameters for DR were identified by Cox-regression multivariate analysis and used for generating a risk assessment model. The study protocol is approved by the local Ethics Committee. Informed written consent is obtained from all study subjects. Results. Increased pre-chemotherapy D-dimer, fibrinogen, and F1+2 levels were significantly associated with a large tumor size (≥ 5 cm) and lymph node positivity. After 3.4 years follow-up, 71 patients experienced a DR. Comparison of the levels of the hypercoagulation variables of patients who experienced relapse versus patients who remained disease-free during follow-up showed that there were no statistical differences for all, but F1+2 biomarker levels, which were significantly higher in the group patients who relapsed [223 (115-618) vs 197 (115-385) pmol/l; p=0.024]. In addition, correlation analyses showed that pre-chemotherapy levels of fibrinogen were significantly and inversely associated with time to relapse (β = -0.317; p=0.012). Cox-multivariate analysis identified F1+2 (HR 2; 95% CI, 1.1-3.6; p=0.019), tumor size ≥ 5cm (HR 2.6; 95% CI, 1.4-4.6; p=0.001), and Luminal B HER2-neg or TN molecular subtypes (HR 3.9; 95% CI, 2.1-7.5; p<0.001) as independent risk factors for DR. Based on these variables, we generated a risk assessment model that significantly identified patients at low- versus high-risk of DR (cumulative incidence: 6.2 vs 20.7%; HR=3.5; p<0.001). Conclusion. Our prospective laboratory data from the HYPERCAN breast cancer subjects were essential for generating a scoring model for DR risk assessment. Future investigations addressing the role of plasma thrombotic biomarkers in breast cancer patients' management are warranted and may provide the rationale for development of new therapeutic strategies.

Abstract Introduction Patients with cancer commonly present with laboratory evidence of hypercoagulability. The HYPERCAN study (ClinicalTrials.gov, ID# NCT02622815) is an ongoing Italian prospective, multicenter, observational study, evaluating the predictive value of thrombotic markers for early cancer diagnosis in healthy subjects and for cancer prognosis and venous thromboembolism in patients with newly diagnosed cancer disease (Thromb Res, 2016). In this analysis of the HYPERCAN study, in a subcohort of consecutive patients with newly diagnosed metastatic non-small cell lung (NSCL) or gastrointestinal (GI) cancers, we aimed to assess whether the pre-chemotherapy levels of thrombotic biomarkers may be predictive of early disease progression (EDP, i.e. within 6 months) and early deaths (i.e. within 1 year). Methods The study cohort included 401 patients [median age: 65 (34-88) years] with metastatic NSCL (n=241) or GI (n=160) cancer. Clinical data were recorded at enrollment and during follow-up visits, disease progression being monitored by imaging. Fibrinogen (Clauss method, IL Werfen, Italy), d-dimer (immuneturbidimetric assay, IL Werfen, Italy), and thrombin generation (TG) potential (CAT assay, Stago, France) were measured in plasma samples collected at patient enrollment, before starting any curative chemotherapy and from a control group of 108 healthy subjects. The study protocol is approved by the local Ethics Committee. Informed written consent is obtained from all study subjects. Data are expressed as median (5th-95th percentile). Results Significantly higher plasma levels of fibrinogen, D-dimer and TG potential were observed in the cohort of cancer patients compared to healthy controls (p<0.01). Among cancer types, fibrinogen levels were significantly greater in NSCL as compared to GI cancer patients [479 (258-934) vs 402 (220-668) mg/dl), p<0.001]. After two year follow up, the cumulative incidence of EDP was 31% (CI 95% 27-36). Of interest, patients with EDP (n=125) vs those without EDP were characterized by significantly (p<0.05) greater pre-chemotherapy levels of leucocytes [9.1 (5.6-21.4) vs 8.4 (4.6-18.2) x109/L], platelets [305 (131-586) vs 283 (148-513) x109/L], fibrinogen [475 (290-913) vs 421 (226-814) mg/dl], and TG endogenous thrombin potential (ETP) [1,919 (1,137-3,086) vs 1,752 (1,264-2,559) nM*min]. In GI cancer, but not in lung cancer patients, multivariate Cox regression analysis according to site of primary tumor identified d-dimer and TG ETP plasma levels, together with GI cancer diagnosis, as independent risk factors for EDP. Concerning mortality, after two year follow-up, the cumulative incidence of overall survival at one year was 63% (CI 95% 58-67), early deaths = 37%. The group of patients who deceased during the first year (n=145) showed significantly (p<0.01) higher leucocyte count [9.7 (5.4-21.6) vs 8 (4.6-16.1) x109/L], plasma fibrinogen [486 (250-846) vs 402 (223-816) mg/dl] and d-dimer [515 (97-3,174) vs 286 (55-1,456) ng/ml] levels. In GI cancer, multivariate Cox regression analysis identified d-dimer and TG ETP plasma levels, leucocytes and platelet counts, and GI cancer diagnosis, as independent risk factors for mortality within 1 year. Differently, none of the hemostatic biomarkers were predictive for mortality in NSCL cancer patients. Conclusions The current analysis of prospectively collected data shows the utility of detecting circulating thrombotic biomarkers in specific cancer types. In particular, in GI metastatic cancer, the levels of D-dimer and TG before starting chemotherapy, together with having a GI cancer, could predict EDP (within 6 months) and early deaths (within 12 months). This was not the case for NSCL cancer. Currently, new tests involving other coagulation biomarkers are ongoing and will be evaluated.

Abstract Background Risk stratification is essential to assess mortality risk and guide treatment in patients with precapillary pulmonary hypertension (PH). We herein compared the accuracy of different currently used PH risk stratification tools and evaluated the significance of particular risk parameters. Methods We conducted a retrospective longitudinal observational cohort study evaluating seven different risk assessment approaches according to the current PH guidelines. A comprehensive assessment including multi-parametric risk stratification was performed at baseline and 4 yearly follow-up time-points. Multi-step Cox hazard analysis was used to analyse and refine risk prediction. Results Various available risk models effectively predicted mortality in patients with precapillary pulmonary hypertension. Right-heart catheter parameters were not essential for risk prediction. Contrary, non-invasive follow-up re-evaluations significantly improved the accuracy of risk estimations. A lack of accuracy of various risk models was found in the intermediate- and high-risk classes. For these patients, an additional evaluation step including assessment of age and right atrium area improved risk prediction significantly. Discussion Currently used abbreviated versions of the ESC/ERS risk assessment tool, as well as the REVEAL 2.0 and REVEAL Lite 2 based risk stratification, lack accuracy to predict mortality in intermediate- and high-risk precapillary pulmonary hypertension patients. An expanded non-invasive evaluation improves mortality risk prediction in these individuals.

Abstract Background Early detection and treatment of cardiometabolic diseases (CMD) in high-risk patients is a promising preventive strategy to anticipate the increasing burden of CMD. The Dutch guideline ‘the prevention consultation’ provides a framework for stepwise CMD risk assessment and detection in primary care. The aim of this study was to assess the outcome of this program in terms of newly diagnosed CMD. Methods A cohort study among 30 934 patients, aged 45–70 years without known CMD or CMD risk factors, who were invited for the CMD detection program within 37 general practices. Patients filled out a CMD risk score (step 1), were referred for additional risk profiling in case of high risk (step 2) and received lifestyle advice and (pharmacological) treatment if indicated (step 3). During 1-year follow-up newly diagnosed CMD, prescriptions and abnormal diagnostic tests were assessed. Results Twelve thousand seven hundred and thirty-eight patients filled out the risk score of which 865, 6665 and 5208 had a low, intermediate and high CMD risk, respectively. One thousand seven hundred and fifty-five high-risk patients consulted the general practitioner, in 346 of whom a new CMD was diagnosed. In an additional 422 patients a new prescription and/or abnormal diagnostic test were found. Conclusions Implementation of the CMD detection program resulted in a new CMD diagnosis in one-fifth of high-risk patients who attended the practice for completion of their risk profile. However, the potential yield of the program could be higher given the considerable number of additional risk factors—such as elevated glucose, blood pressure and cholesterol levels—found, requiring active follow-up and presumably treatment in the future.

Pendahuluan. Hiperkoagulasi merupakan faktor yang mendasari tingginya mortalitas akibat kejadian tromboemboli vena pada pasien kanker. Kemoterapi merupakan salah satu faktor yang diduga berkontribusi terhadap status hiperkoagulasi pada pasien kanker. Studi ini bertujuan untuk mengevaluasi perubahan status koagulasi yang ditandai dengan kadar D-dimer pada pasien kanker yang menjalani kemoterapi.Metode. Studi ini merupakan studi kohort prospektif di Pusat Kanker Nasional Indonesia yang melibatkan pasien kanker yang sudah terkonfirmasi melalui pemeriksaan histopatologi, dan memulai kemoterapi pada periode Mei hingga Juli 2018. Perubahan status koagulasi dinilai melalui kadar D-dimer plasma. Kadar D-dimer diukur sebelum dan 7 hari setelah kemoterapi. Analisis statistik menggunakan uji t berpasangan untuk menilai kemaknaan perubahan kadar D-dimer plasma sebelum dan setelah kemoterapi.Hasil. Sejumlah 89 pasien memenuhi kriteria inklusi, yang mana 74,2% adalah perempuan dan hampir separuh dari keseluruhan subjek terdiagnosis kanker payudara (44,9%). Mayoritas subjek (69,6%) terdiagnosis pada stadium III atau IV. Sejumlah 12,4% dari subjek mendapatkan kemoterapi berbasis cisplatin. Terdapat perbedaan yang bermakna antara kadar D-dimer sebelum dan setelah kemoterapi (p = 0,05). Studi ini juga menemukan perbedaan bermakna kadar D-dimer sebelum dan sesudah kemoterapi pada pasien kanker stadium III (t(35) = 2,48, p = 0,02) dan stadium IV (t(25) = 2,14, p = 0,04). Tidak terdapat perbedaan bermakna antara kadar D-dimer sebelum dan setelah kemoterapi pada pasien stadium I dan II. Analisis lanjutan berdasarkan kelompok kemoterapi menunjukkan bahwa terdapat perubahan kadar D-dimer yang bermakna pada kelompok yang mendapatkan kemoterapi cisplatin (t(10) = 2,31, p = 0,04), namun tidak pada kelompok yang mendapat kemoterapi non-cisplatin (t(77) = 1,50, p = 0,14).Simpulan. Terdapat perbedaan bermakna status koagulasi yang ditandai dengan kadar D-dimer 7 hari pasca mendapatkan kemoterapi, khususnya pada pasien kanker stadium III atau IV dan mendapatkan kemoterapi berbasis cisplatin. Kata Kunci: Cisplatin, kanker, kemoterapi, status koagulasiChange of Coagulation Status in Solid Cancer Patients Undergoing Chemotherapy in Indonesia: A Prospective Cohort StudyIntroduction. Cancer-associated hypercoagulability was an underlying factor of high mortality of cancer due to venous thromboembolism. Chemotherapy is proposed as one of the contributing factors of the hypercoagulable state. We aim to evaluate the change of coagulation status, which was marked by D-dimer level, in cancer patients receiving chemotherapy.Methods. This is a prospective cohort study in Indonesian national cancer center which involves all adult histologically-confirmed-cancer patients who started chemotherapy between May and July 2018. The coagulation status is assessed by plasma of D-dimer level. We measured D-dimer before chemotherapy and one week after chemotherapy. Paired t-test was performed to assess the significant difference in D-dimer levels before and after chemotherapy.Results. A total of 89 patients fulfilled the eligibility criteria, of whom 74.2% were female and almost half of total subjects (44.9%) were breast cancer patients. Majority of subjects (69.6%) were stage III or stage IV cancer. There were 12.4% of subjects received cisplatin-based chemotherapy. There was a marginally significant difference in plasma level of D-dimers before and after chemotherapy (p = 0.05). We also found significant differences between D-dimer level before and after chemotherapy in stage III patients (t(35) = 2.48, p = 0.02) and stage IV patients (t(25) = 2.14, p = 0.04). There was no significant difference between D-dimer level before and after chemotherapy in stage I and stage II patients. Subgroup analyses based on chemotherapy agents showed that there was significant D-dimer change in cisplatin-based chemotherapy subjects (t(10) = 2.31, p = 0.04), but not in non-cisplatin-based chemotherapy subjects (t(77) = 1,50, p = 0.14).Conclusion. Compared to before chemotherapy, there is a significant difference of coagulation status marked by plasma D-dimer level one week after chemotherapy, particularly in patients with stage III or stage IV cancer and in patients receiving cisplatin-based chemotherapy.

Abstract Background Estimates of contralateral breast cancer (CBC) risk in the modern treatment era by year of diagnosis and characteristics of the first breast cancer are needed to assess the impact of recent advances in breast cancer treatment and inform clinical decision making. Methods We examined CBC risk among 419,818 women (age 30–84 years) who were diagnosed with a first unilateral invasive breast cancer and survived ≥ 1 year in the US Surveillance, Epidemiology, and End Results program cancer registries from 1992 to 2015 (follow-up through 2016). CBC was defined as a second invasive breast cancer in the contralateral breast ≥ 12 months after the first breast cancer. We estimated standardized incidence ratios (SIRs) of CBC by year of diagnosis, age at diagnosis, and tumor characteristics for the first breast cancer. Cumulative incidence of CBC was calculated for women diagnosed with a first breast cancer in the recent treatment era (2004–2015, follow-up through 2016). Results Over a median follow-up of 8 years (range 1–25 years), 12,986 breast cancer patients developed CBC. Overall, breast cancer patients had approximately twice the risk of developing cancer in the contralateral breast when compared to that expected in the general population (SIR = 2.21, 95% CI = 2.17–2.25). SIRs for CBC declined by year of first diagnosis, irrespective of age at diagnosis and estrogen receptor (ER) status (p-trends < 0.001), but the strongest decline was after an ER-positive tumor. The 5-year cumulative incidence of CBC ranged from 1.01% (95% CI = 0.90–1.14%) in younger women (age < 50 years) with a first ER-positive tumor to 1.89% (95% CI = 1.61–2.21%) in younger women with a first ER-negative tumor. Conclusion Declines in CBC risk are consistent with continued advances in breast cancer treatment. The updated estimates of cumulative incidence inform breast cancer patients and clinicians on the risk of CBC and may help guide treatment decisions.
