Prognostic Significance of Pretreatment Plasma D-dimer Levels in EGFR-Positive Advanced Non-Small Cell Lung Cancer Patients Receiving Osimertinib: A Multicentre Retrospective Study. Int J Gen Med 2023; 16:5481-5491. [PMID: 38021044 PMCID: PMC10680375 DOI: 10.2147/ijgm.s437495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 11/09/2023] [Indexed: 12/01/2023] Open
Abstract
Purpose This study examined the association between plasma D-dimer levels and overall survival (OS) in advanced non-small cell lung cancer (NSCLC) patients treated with osimertinib. Methods In this multicenter study, 88 patients with advanced non-small cell lung cancer (NSCLC) carrying epidermal growth factor receptor (EGFR) mutations and receiving osimertinib were enrolled. The target independent and dependent variables were the D-dimer levels before osimertinib treatment and OS time, respectively. The t-test or chi-square test was utilized to analyze the variances among various groups. The predictive significance of D-dimer for overall survival (OS) was assessed using Kaplan-Meier survival analysis and the Cox proportional hazard regression model. Results The selected patients had an average age of 58.01±10.72 years, with females comprising 54.55%. Based on their D-dimer levels, the patients were categorized into three groups: low-level (< 0.6 mg/L), middle-level (0.6 ~ 2 mg/L), and high-level (≥ 2 mg/L). After accounting for possible confounding variables, the Cox proportional hazard model showed that increased D-dimer levels were linked to a greater likelihood of death (HR 2.28, 95% CI = 1.09 ~ 4.76, p = 0.029). Importantly, there was a significant trend indicating that as D-dimer levels rose, the risk of mortality also increased (p for trend, HR 1.15, 95% CI = 1.03 ~ 1.28, p = 0.012). Consistently comparable outcomes were noted in the majority of subcategories. Patients with low-middle and high D dimer levels had a median OS of 28.6 and 17 months, respectively (p =0.014). Conclusion In conclusion, elevated levels of D-dimer in the bloodstream were found to have a significant negative correlation with the overall survival (OS) of patients with EGFR-positive non-small cell lung cancer (NSCLC) who underwent treatment with osimertinib.

Cancer Med 2023; 12:15831-15840. [PMID: 37326149 PMCID: PMC10469714 DOI: 10.1002/cam4.6222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 05/31/2023] [Accepted: 06/01/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND/AIMS Response to therapy after using immune checkpoint inhibitors (ICIs) is unpredictable due to significant interindividual variation in efficacy among advanced non-small cell lung cancer (NSCLC) patients. The current study centered on the identification of perivascular blood biomarkers for predicting the effectiveness of anti-programmed cell death protein 1 (anti-PD-1) treatment and progression-free survival (PFS) in advanced NSCLC patients, that could be applied to help determine how to change treatment plans therapeutic regimens for optimizing clinical benefits. METHODS A comprehensive review of 100 advanced or recurrent NSCLC patients receiving anti-PD-1 therapy (Camrelizumab, pembrolizumab, sintilimab, or nivolumab) was conducted between January 2018 and April 2021 in Tianjin Medical University Cancer Hospital. The cutoff values of D-dimer were selected from rom our previous study, and interleukin-6 (IL-6) was divided according to the median. Using computed tomography, tumor response was evaluated in accordance with the Response Assessment Criteria in Solid Tumors, version 1.1. RESULTS High IL-6 level in advanced NSCLC patients was predictive of low efficacy and a short PFS duration after anti-PD-1 therapy. An increased D-dimer value of 981 ng/mL was significantly predictive of disease progression in NSCLC patients treated with anti-PD-1 and high D-dimer expression predictive of short duration of PFS. Further studies on the correlation between IL-6, D-dimer, and anti-PD-1 efficacy in NSCLC patients stratified by gender revealed that D-dimer and IL-6 levels were significantly associated with the risk of PFS in male patients. CONCLUSIONS High IL-6 content in peripheral blood in patients with advanced non-small cell lung cancer may contribute to poor anti-PD-1 efficacy and short duration of PFS through inducing alterations in the tumor microenvironment. D-dimer in peripheral blood is predictive of hyperfibrinolysis and contributes to the release of tumor-driven specific factors, leading to poor effects of anti-PD-1 therapy.

Clin Med Insights Oncol 2023; 17:11795549231175221. [PMID: 37426681 PMCID: PMC10328178 DOI: 10.1177/11795549231175221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Accepted: 04/20/2023] [Indexed: 07/11/2023] Open
Abstract
Background Several biomarkers or risk factors have been identified and several prediction models exist. The major limitations inherent in these models include cost-ineffectiveness and lack of systematic stratification of risk factors resulting in the inclusion of clinically insignificant biomarkers in the models. This review aimed to systematically stratify the risk factors of lung cancer-associated venous thromboembolism (VTE) and determine the critical point for preemptive intervention. Methods This systematic review was structured as per the Preferred Reporting Item for Systematic Reviews and Meta-analyses. We searched MEDLINE, PubMed, Cochrane Library, CINAHL, Academic Search Complete, and PsycINFO from the onset to June 2022. We included studies that reported the risk factors of lung cancer-associated VTE and corresponding risk estimates, irrespective of treatment status but studies were excluded if patients were on anti-VTE medications. We employed random effects models of meta-analysis and computed risk stability index and risk weight (Rw) to achieve the review objectives. The review protocol is registered with PROSPERO (CRD42022336476). Results The clinically significant risk factors of VTE in lung cancer patients were D-dimer (odds ratio [OR] = 5.510, 95% CI = 2.6-11.7; Rw = 5.0), albumin (OR = 2.2, 95% CI = 1.0-4.8; Rw = 1.79), leukocyte (OR = 2.48, 95% CI = 1.9-3.2; Rw = 1.77), histological type (OR = 1.69 , 95% CI = 1.2-2.4; Rw = 1.3), age (OR = 1.56; Rw = 0.99), and hemoglobin (OR = 1.85, 95% CI = 1.3-2.6; Rw = 0.92). Based on the distribution of Rw across risk factors, the critical point (upper third of the upper quartile class) was 4.5 and may mark the point at which preemptive intervention should be commenced. Conclusions Targeted screening for VTE in lung cancer patients could be patient-specific and should be based on a combination of the most significant risk factors required to meet the critical point, provided that such a combination is affordable as illustrated in the ALBAH model. Registration The review protocol is registered with PROSPERO (ID: CRD42022336476).

J Thorac Dis 2022; 14:4125-4135. [PMID: 36389301 PMCID: PMC9641356 DOI: 10.21037/jtd-22-1363] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 10/19/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND Plasma D-dimer is of great significance for the clinical exclusion of tumor-related thrombosis. Previous studies have shown its predictive role in non-small cell lung cancer (NSCLC) treated with chemotherapy. However, whether pretreatment D-dimer could predict the efficacy and prognosis in NSCLC patients treated with immune checkpoint inhibitors (ICIs) remains unclear. METHODS Advanced NSCLC patients treated with ICIs at the Chinese PLA General Hospital between January 2015 and March 2019 were enrolled. Patients were divided into a pretreatment normal D-dimer group (≤0.5 µg/mL) and high D-dimer group (>0.5 µg/mL). Optimization-based approach was applied to balance baseline covariates between the 2 groups, including age, sex, histological type, smoking history, stage, Eastern Cooperative Oncology Group Performance Status (ECOG PS), lines of treatment, ICI drugs, brain metastasis, treatment type, and D-dimer levels. Kaplan-Meier analysis and Cox proportional hazards model were used for analyzing survival data, including progression-free survival (PFS, the time from initial ICI treatment to PD or death), overall survival (OS, the time between initial ICI treatment and death), and hazard ratio (HR). Follow-up of all patients was performed by searching electronic medical records and counseling telephone. The follow-up cut-off date was July 6, 2020. RESULTS This study included 277 advanced NSCLC patients. Among the enrolled patients, 23.1% were female, 64.6% had non-squamous cell lung cancer, and 79.4% were stage IV. Univariate and multivariate analysis showed that pretreatment high D-dimer levels were independently associated with shortened PFS and OS (P<0.01). Subgroup analysis confirmed that pretreatment high D-dimer levels were associated with poor prognosis in most subsets. After balancing baseline covariates between the high D-dimer group and normal D-dimer group, the results indicated that patients with pretreatment high D-dimer levels had significantly shorter PFS [median: 6.4 vs. 11.5 months; HR, 1.70; 95% confidence ratio (CI): 1.25-2.37; P<0.001] and OS (median: 12.7 vs. 30.4 months; HR, 2.29; 95% CI: 1.54-3.41; P<0.001) than those with pretreatment normal D-dimer levels. CONCLUSIONS Pretreatment plasma D-dimer could serve as a convenient prognostic biomarker for advanced NSCLC patients receiving ICI treatment. Patients with pretreatment high D-dimer levels may have poor PFS and OS.

Abstract
Plasma D-dimer is a screening marker for thrombosis and hemostasis disorders. Falsely elevated D-dimer may result in misdiagnosis and potentially invasive investigations. Therefore, identifying falsely elevated D-dimer is of great value in laboratory practice. D-dimer is determined by immunoassay and vulnerable to heterophilic antibody interference. Here, we reported a case of falsely elevated D-dimer partially caused by heterophilic antibodies. Dilution test, polyethylene glycol precipitation, heterophilic blocking reagent and method comparison were used to identify the heterophilic antibody interference. All these methods, except for the heterophilic blocking reagent, revealed the existence of heterophilic antibody interference. Polyethylene glycol precipitation failed to reduce the D-dimer to its reference interval. Therefore, we conclude that the falsely elevated D-dimer is partially caused by heterophilic antibody interference.

Abstract
Background Hypercoagulability in lung cancer patients is associated with a high incidence of mortality and morbidity in the world. Therefore, this meta‐analysis aimed to explore the correlation of the basic coagulation abnormalities in lung cancer patients compared with the control. Method PubMed, Scopus, and other sources were employed to identify eligible studies. The outcome variable was expressed using mean ± standard deviation (SD). Heterogeneity among studies and publication bias were evaluated. The quality of included studies was also assessed based on Newcastle–Ottawa Scale checklist. Result Finally, through a total of eight studies, prolonged prothrombin time (PT; standard mean difference [SMD]: 1.29; 95% CI: 0.47–2.11), plasma D‐dimer value (SMD 3.10; 95% CI 2.08–4.12), fibrinogen (SMD 2.18; 95% CI:1.30–3.06), and platelet (PLT) count (SMD 1.00; 95% CI 0.84–1.16) were significantly higher in lung cancer patients when compared with the control group. The single‐arm meta‐analysis also showed that compared with control, lung cancer patients had high pooled PT 13.7 (95% CI:12.2–15.58) versus 11.79 (95% CI = 10.56–13.02), high D‐dimer 275.99 (95% CI:172.9–11735.9) versus 0.2 (95% CI:0.20–0.37), high plasma fibrinogen 5.50 (95% CI:4.21–6.79) versus 2.5 (95% CI:2.04–2.91), and high PLT count 342.3 (95% CI:236.1–448.5) versus 206.6 (95% CI:176.4–236.7). Conclusion In conclusion, almost all the coagulation abnormalities were closely associated with lung cancer, and hence coagulation indexes provide an urgent clue for early diagnosis and timely management.

Abstract
Introduction Thymic epithelial tumors are the most common mediastinal tumors. Despite the high survival rate after surgery, some patients still require postoperative adjuvant therapy and closer follow-up. Hematological indicators such as biochemical routines and coagulation indicators have been reported to be independently associated with the prognosis of various malignancies. Therefore, we included hematological indicators in the analysis. Methods The data of 105 patients with thymic epithelial tumors were retrospectively collected from Sun Yat-sen University Cancer Center, and the patients with missing preoperative hematological indicators were excluded. X-tile software was used to obtain the best cutoff value of each preoperative hematological indicator, and COX regression analysis and Kaplan-Meier survival curves were used to demonstrate statistically significant results. Results COX univariate regression analysis of all patients showed that Masaoka stage, T stage, WHO histologic types, D-dimer, albumin-fibrinogen ratio (AFR), Fibrinogen (Fbg) were associated with postoperative overall survival ( P < .05). T stage, WHO histologic types, D-dimer, and AFR were associated with postoperative recurrence-free survival ( P < .05). Finally, multivariate regression analysis showed that T stage, D-dimer levels were independently associated with postoperative overall survival (OS) and recurrence-free survival (RFS) in patients with thymic epithelial tumors. Conclusions For thymic epithelial tumors, higher preoperative D-dimer levels predict poorer survival and shorter recurrence-free survival. This may help guide postoperative adjuvant therapy and follow-up patterns in patients with thymic epithelial tumors.

Abstract
OBJECTIVE Although the significance of increased plasma D-dimer levels in activating coagulation and fibrinolysis has been reported, it is still controversial whether it can be used to predict the prognosis of lung cancer patients. This meta-analysis was performed to explore the beneficial role of plasma D-dimer as a prognostic factor in lung cancer patients according to a larger sample capacity. MATERIALS AND METHODS MEDLINE, EMBASE, and Cochrane Central databases were searched from inception to January 2021. The data are mainly hazard ratio(HR) with 95% confidence interval (CI) and Kaplan-Meier survival curves. The publication bias was examined by Egger's test. RESULTS Finally, a total of 28 studies, enrolling 8452 patients were included in the current meta-analysis. Our results showed that the OS (HR = 1.742, 95%CI:1.542-1.969, P < 0.001) and PFS (HR = 1.385, 95%CI:1.169-1.641, P = 0.003) in the high D-dimer group were significantly lower than those in the low D-dimer group. Subgroup analysis suggested that localization, detection methods and disease stage had an important effect on the prognosis. CONCLUSION This meta-analysis revealed that the high plasma D-dimer level leads to lower survival than in the low D-dimer level, which might provide an important clue for high plasma D-dimer level as an independent factor of poor prognosis in patients with lung cancer.
