Roy DC, Wang TF, Carrier M, Mallick R, Burger D, Hawken S, Wells PS. Thrombophilia gene mutations predict venous thromboembolism in ambulatory cancer patients receiving chemotherapy. J Thromb Haemost 2023; 21:3184-3192. [PMID: 37536569 DOI: 10.1016/j.jtha.2023.07.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 07/17/2023] [Accepted: 07/21/2023] [Indexed: 08/05/2023]
Abstract
BACKGROUND Inherited thrombophilia and cancer both independently increase the risk of venous thromboembolism (VTE). However, whether the increased VTE risk associated with inherited thrombophilia exists in cancer patients is less clear. OBJECTIVES Our objective was to determine the influence of inherited thrombophilia on VTE and bleeding risk in moderate-to-high-risk ambulatory cancer patients receiving chemotherapy. METHODS We conducted a post hoc analysis using blood samples from patients enrolled in the AVERT trial to determine if previously recognized thrombophilia gene mutations (prothrombin factor [F] II G20210A, FXI, fibrinogen gamma, serpin family A member 10, FV K858R, FXIII, FV Leiden [FVL], and ABO blood) were associated with VTE or bleeding during the 7-months after starting chemotherapy. Logistic regression was used to compare heterozygous and homozygous mutations (combined) to wild-type. VTE rates, bleeding rates, and risk differences for mutations stratified by prophylactic anticoagulation use were calculated. RESULTS Of the 447 patients, there were 39 VTE and 39 bleeding events. The odds of VTE were significantly increased with FVL mutation and non-O blood type (odds ratio [OR]: 5.2; 95% CI: 1.9-14.7 and OR: 2.7; 95% CI: 1.2-6.1, respectively). The use of anticoagulation prophylaxis resulted in complete protection in FVL patients, whereas those not receiving anticoagulation had a VTE rate of 119 per 100 patient-years. Lower VTE rates were also observed in non-O blood type patients taking prophylactic anticoagulation. No other thrombophilia genes tested were significantly associated with VTE or bleeding. CONCLUSION Our results indicate that FVL mutation and ABO blood type may be important VTE predictors in cancer patients starting chemotherapy.

Impact of hereditary thrombophilia on cancer-associated thrombosis, tumour susceptibility and progression: A review of existing evidence. Biochim Biophys Acta Rev Cancer 2022; 1877:188778. [PMID: 35963552 DOI: 10.1016/j.bbcan.2022.188778] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 07/22/2022] [Accepted: 08/08/2022] [Indexed: 11/24/2022]
Abstract
Venous thromboembolism (VTE) is a cardiovascular disorder frequently diagnosed among cancer patients. Aside from being common, VTE severely deteriorates the prognosis of these patients as they face a higher risk of morbidity and mortality, which makes clinical tools able to identify the patients more prompt to thrombogenesis very attractive. Over the years, several genetic polymorphisms have been linked with VTE susceptibility in the general population. However, their clinical usefulness as predictive biomarkers for cancer-related VTE is yet unclear. Furthermore, as a two-way association between cancer and VTE is well-recognized, with haemostatic components fuelling tumour progression, haemostatic gene polymorphisms constitute potential cancer predictive and/or prognostic biomarkers as well. Thus, in this article, we review the existing evidence on the role of these polymorphisms on cancer-related VTE and their impact on cancer onset and progression. Despite the promising findings, the existing studies had inconsistent results most likely due to their limited statistical power and population heterogeneity. Future studies are therefore required to clarify the role of these polymorphisms in setting of malignancy.

Abstract
Venous thromboembolism (VTE) is one of the major causes of pregnancy-related mortality and morbidity. This study aimed to determine the frequency of factor V Leiden (FVL) and prothrombin G20210A polymorphisms and measure the plasma levels of protein C (PC), protein S (PS) and antithrombin (AT) in pregnant women with VTE and healthy pregnant women. This prospective case-control study determined the frequencies of FVL G1691A and prothrombin G20210A polymorphisms and measured the plasma levels of PC, PS and AT in 198 pregnant women with VTE and 198 healthy pregnant women. Allele-specific polymerase chain reaction (ASPCR) was used to detect the FVL G1691A polymorphisms and prothrombin G20210A gene mutations. The FVL G1691A polymorphism and prothrombin G20210A gene mutations were detected only in pregnant women with VTE, with frequencies of 4.0 and 0.5%, respectively. The highest frequency of FVL G1691A polymorphism was observed in patients with deep vein thrombosis (DVT) and positively associated with contraceptive use and termination. Pregnant women with VTE had significantly lower levels of PC, PS and AT than those of controls. In conclusion, among the VTE cases, FVL G1691A polymorphism and PC, PS and AT deficiencies were the most common findings in patients presenting with DVT. Antithrombin deficiency was more common than PC and PS deficiencies. Contraceptive use, high body mass index (BMI) and termination correlated strongly with FVL G1691A polymorphism and PC and PS deficiencies in patients with VTE.

Prothrombotic genotypes and risk of venous thromboembolism in occult cancer. Thromb Res 2021; 205:17-23. [PMID: 34237679 DOI: 10.1016/j.thromres.2021.06.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 06/24/2021] [Accepted: 06/26/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND Studies have reported that the combination of some prothrombotic genotypes and overt cancer yields a synergistic effect on VTE risk. Whether individual prothrombotic genotypes or number of risk alleles in a genetic risk score (GRS) affect VTE risk in occult cancer have not been addressed. The aim of this study was to investigate the joint effect of five prothrombotic genotypes and occult cancer on VTE risk. METHODS Cases with incident VTE (n = 1566) and a subcohort (n = 14,537) were sampled from the Scandinavian Thrombosis and Cancer Cohort (1993-2012). Five single nucleotide polymorphisms previously reported in a GRS were genotyped: ABO (rs8176719), F5 (rs6025), F2 (rs1799963), FGG (rs2066865) and F11 (rs2036914). Hazard ratios (HRs) for VTE by individual SNPs and GRS were estimated according to non-cancer and occult cancer (one year preceding a cancer diagnosis) exposure. RESULTS Occult cancer occurred in 1817 subjects, and of these, 93 experienced a VTE. The VTE risk was 4-fold higher (HR 4.05, 95% CI 3.28-5.00) in subjects with occult cancer compared with those without cancer. Among subjects with occult cancer, those with VTE had a higher proportion of prothrombotic and advanced cancers than those without VTE. The VTE risk increased according to individual prothrombotic genotypes and GRS in cancer-free subjects, while no such effect was observed in subjects with occult cancer (HR for ≥4 versus ≤1 risk alleles in GRS: 1.14, 95% CI 0.61-2.11). CONCLUSIONS Five well-established prothrombotic genotypes, individually or combined, were not associated with increased risk of VTE in individuals with occult cancer.

Combined effects of five prothrombotic genotypes and cancer on the risk of a first venous thromboembolic event. J Thromb Haemost 2020; 18:2861-2869. [PMID: 32671915 DOI: 10.1111/jth.15011] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 06/08/2020] [Accepted: 07/10/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND The role of combined prothrombotic genotypes in cancer-related venous thromboembolism (VTE) is scarcely studied. We aimed to investigate the impact of a 5-single nucleotide polymorphism (SNP) score on the risk of VTE in patients with and without cancer using a population-based case-cohort. METHODS Cases with a first VTE (n = 1493) and a subcohort (n = 13 072) were derived from the Tromsø Study (1994-2012) and the Nord-Trøndelag Health Study (1995-2008). Five SNPs previously reported as a risk score were genotyped: ABO (rs8176719), F5 (rs6025), F2 (rs1799963), FGG (rs2066865), and F11 (rs2036914). Hazard ratios (HRs) for VTE were estimated according to cancer status and the number of risk alleles in the 5-SNP score (0-1, 2-3, and ≥4 alleles). RESULTS During a median follow-up of 12.3 years, 1496 individuals were diagnosed with cancer, of whom 232 experienced VTE. The VTE risk increased with the number of risk alleles in the 5-SNP score among subjects without and with cancer. In cancer-free subjects, the HR was 2.17 (95% confidence interval [CI] 1.79-2.62) for ≥4 versus 0-1 risk alleles. In cancer patients, the corresponding HR was 1.93 (95% CI 1.28-2.91). The combination of cancer and ≥4 risk alleles yielded a 17-fold (HR 17.1, 95% CI 12.5-23.4) higher risk of VTE compared with cancer-free subjects with 0-1 risk alleles. CONCLUSION The risk of VTE increases with the number of prothrombotic risk alleles in subjects with and without cancer, and the combination of prothrombotic risk alleles and cancer leads to a highly elevated risk of VTE.

Abstract
Most of the patients undergoing treatment for cancer require placement of a
totally implantable venous access device to facilitate safe delivery of
chemotherapy. However, implantable ports also increase the risk of deep vein
thrombosis and related complications in this high-risk population. The objective
of this study was to assess the incidence of upper-extremity deep vein
thrombosis (UEDVT) in patients with breast cancer to determine whether the risk
of UEDVT was higher with chest versus arm ports, as well as to determine the
importance of previously reported risk factors predisposing to UEDVT in the
setting of active cancer. We retrospectively reviewed the medical records of 297
women with breast cancer who had ports placed in our institution between the
dates of December 1, 2010, and December 31, 2016. The primary outcome was the
development of radiologically confirmed UEDVT ipsilateral to the implanted port.
Overall, 17 of 297 study subjects (5.7%) were found to have UEDVT. There was 1
documented case of associated pulmonary embolism. Fourteen (9.5%) of 147
subjects with arm ports experienced UEDVT compared with only 3 (2.0%) of 150
subjects with chest ports (P = .0056). Thus, implantation of
arm ports as opposed to chest ports may be associated with a higher rate of
UEDVT in patients with breast cancer.

Abstract
AbstractThrombophilia may be anticipated by single or combined hereditary defects in encoding genes factor V, Prothrombin, and MTHFR. The aim of this study was to determine the prevalence and associated risks of V Leiden (G1691A), Prothrombin (G20210A), and MTHFR (C677T) mutations in Saudi women with Deep Vein Thrombosis (DVT) and women with recurrent pregnancy loss (RPL). Protein C and protein S activity were measured to determine combined effects, if any. We examined 60 women with a history of DVT and 60 with RPL, extracted DNA from EDTA blood and determined three mutations by using multiplex PCR reactions followed by Strip Assay KIT. Pro C Global assay was used to determine the cutoff value [PCATNR = 0.80]. Protein C/S chromogenic assay was used to estimate protein C and S percentages. Frequency of Factor V Leiden G/A genotype in patients with DVT 7 (11.6%) had a significant association for DVT χ2 (OR = 5.1, P = 0.03). In women with RPL the three mutations did not show any significant association, levels of Protein C, protein S and PCAT-NR in patient groups not different from controls (P > 0.05). In conclusion, we recommend expanding on these data to provide larger-scale studies.

Abstract
Venous thromboembolism (VTE) is a common complication in cancer patients. Several genetic risk factors related to thrombophilia are known; however, their contributions to thrombotic tendency in cancer patients have conflicting results. We aimed to determine the prevalence of factor V Leiden (FVL), prothrombin (PTH) G20210A and methylene tetrahydrofolate reductase (MTHFR) C677T gene polymorphisms in Egyptian nonmetastatic cancer patients and their influence on thrombosis risk in those patients. Factor V Leiden, PTH G20210A and MTHFR C677T polymorphisms were detected in 40 cancer patients with VTE (group 1) and 40 cancer patients with no evidence of VTE (group 2) by PCR-based DNA analysis. Factor V and MTHFR mutations were higher in group 1 than in group 2 (factor V heterozygous mutation: 20 vs. 7.5%, homozygous mutation: 10 vs. 2.5%; MTHFR heterozygous mutation: 40 vs. 25%, homozygous mutation 5 vs. 0%, respectively) (P = 0.03). Mortality rate was higher in group 1 (75%) than in group 2 (25%; P < 0.001). No difference was found between those groups regarding PTH mutation (P = 1). Mortality rate was higher in the presence of homozygous and heterozygous factor V mutation (100 and 82%, respectively) compared to the wild type (41%) (P = 0.0006). Having any of the three studied gene mutations worsened the overall survival (P = 0.0003). Cox regression proved that both thrombosis and presence of factor V mutation are independent factors affecting survival in cancer patients (P < 0.001 and P = 0.01, respectively). In conclusion, there is an association between factor V and MTHFR mutations and risk of VTE in Egyptian cancer patients. Thrombosis and presence of factor V mutation are independent factors that influence survival in those patients.

Abstract
Anesthetic management of patients with coagulation disorders presents safety and technical challenges. This case describes a 58-year-old woman with factor V Leiden mutation who required distal saphenous vein harvest and axillo-brachial bypass to treat axillary artery occlusion. The patient underwent surgery with satisfactory anesthesia using infraclavicular brachial plexus block, thoracic paravertebral block, and unilateral subarachnoid block. These three regional anesthetic interventions were performed in lieu of general anesthesia to minimize risks of thrombotic events, pain, and to decrease recovery time. Despite higher failure rates of regional anesthesia, longer time required for procedures, and added discomforts during surgery, the benefits may outweigh risks for selected high-risk patients, including those with factor V Leiden mutations.
