Prognostic Value of Plasma D-dimer in Patients with Resectable Esophageal Squamous Cell Carcinoma in China

D-dimer levels predict the treatment efficacy and prognosis of esophageal squamous cell carcinoma treated with PD-1/PD-L1 inhibitors

OBJECTIVES

This study aimed to explore the value of D-dimer levels in predicting the treatment efficacy and prognosis of advanced esophageal squamous cell carcinoma (ESCC) treated with programmed cell death protein-1/programmed death-ligand 1 (PD-1/PD-L1) inhibitors.

METHODS

The study retrospectively analyzed 233 ESCC patients who received PD-1/PD-L1 inhibitors. The optimal cut-off values for platelets, fibrinogen, and D-dimer were calculated based on maximally selected rank statistics for patients' overall survival. Univariate and multivariate analyses of progression-free survival and overall survival were conducted by Cox proportional hazards regression model. Subgroup analyses of D-dimer levels in different fibrinogen levels were performed by log-rank test.

RESULTS

The multivariate Cox regression analyses demonstrated that ESCC patients with D-dimer levels > 236 ng/mL exhibited both poorer progression-free survival (P = 0.004) and overall survival (P < 0.0001) compared to those with low D-dimer levels. The subgroup analyses further indicated that in the group of low fibrinogen levels, the higher D-dimer levels of ESCC patients exhibited significantly shorter progression-free survival (P = 0.0021) and overall survival (P < 0.0001).

CONCLUSIONS

The study revealed that the D-dimer levels possess predictive value for the treatment efficacy and prognosis of ESCC patients treated with PD-1/PD-L1 inhibitors.

Prognostic value of red blood cell distribution width and D-Dimer in diffuse large B-cell lymphoma: Systematic review and meta-analysis

BACKGROUND

The significant role of red blood cell distribution width (RDW) and D-Dimer as prognostic factors in patients with some blood malignancies has been reported recently.

AIM

We designed and performed a meta-analysis to investigate the prognostic roles of RDW and D-Dimer in subjects with diffuse large B-cell lymphoma (DLBCL).

MATERIALS AND METHODS

We systematically reviewed PubMed-Medline, SCOPUS, EMBASE, Web of Science Core Collection, and Google Scholar up to the present to look for publications on prognostic effects of RDW and D-Dimer in DLBCL patients. For investigation of the associations between RDW and D-Dimer with the overall survival (OS) and progression-free survival (PFS) of the DLBCL cases, hazard ratio (HR) with 95% confidence intervals (CIs) was used.

RESULTS

We included 13 eligible studies in the present meta-analysis. The results of pooled analysis showed that increased levels of RDW was related to poor OS (HR = 2.01, 95% CI: 1.62-2.48, p value <.01, I2  = 0%) and poor PFS (HR = 1.52, 95% CI: 1.24-1.85, p value <.01, I2  = 16%) among the DLBCL patients. Similarly, a significant relationship was found between increased D-Dimer and poor OS (HR = 2.30, 95% CI: 1.03-5.14, p value <.05, I2  = 95%) of the DLBCL patients as well. In addition, there was no significant heterogeneity in OS (p value H = 0.65) and PFS (p value H = 0.31) related to RDW among studies included in the meta-analysis.

CONCLUSION

Our finding clearly confirmed that elevated RDW levels and D-Dimer were associated with adverse OS and PFS in DLBCL.

Factors affecting the ORR after neoadjuvant therapy of TP regimen combined with PD-1 inhibitors for esophageal cancer

The aim of this study is to evaluate the factors affecting the objective response rate (ORR) after neoadjuvant therapy of taxol plus platinum (TP) regimen combined with programmed cell death protein-1 (PD-1) inhibitors for esophageal cancer, and establish a predictive model for forecasting ORR. According to the inclusion and exclusion criteria, consecutive esophageal cancer patients who were treated in the First Affiliated Hospital of Xi'an Jiaotong University from January 2020 to February 2022 were enrolled in this study as a training cohort, while patients who were treated in the Shaanxi Provincial Cancer Hospital Affiliated to Medical College of Xi'an Jiaotong University from January 2020 to December 2021 were enrolled as a validation cohort. All patients were treated with resectable locally advanced esophageal cancer and received neoadjuvant chemotherapy combined with immunotherapy. The ORR was defined as the sum of complete pathological response, major pathological response and partial pathological response. Logistic regression analysis was performed to determine the factors that might be related to the ORR of the patients after neoadjuvant therapy. The nomogram based on the result of regression analysis was established and verified to predict the ORR. In this study, 42 patients were included as training cohort and 53 patients were included as validation cohort. Chi-square analysis showed that neutrophil, platelet, platelet-to-lymphocytes ratio (PLR), systemic immune-inflammation index (SII), D-dimer and carcinoembryonic antigen (CEA) between ORR group and non-ORR group were significantly different. Logistic regression analysis showed that aspartate aminotransferase (AST), D-dimer and CEA were independent predictors of ORR after neoadjuvant immunotherapy. Finally, a nomogram was established based on AST, D-dimer and CEA. Internal validation and external validation revealed that the nomogram had a good ability to predict ORR after neoadjuvant immunotherapy. In conclusion, AST, D-dimer and CEA were the independent predictors of ORR after neoadjuvant immunotherapy. The nomogram based on these three indicators showed a good predictive ability.

Stage-Specific Survival From Esophageal Cancer in China and Implications for Control Strategies: A Systematic Review and Meta-Analyses

Background and Aims

Esophageal cancer claims more than 500,000 deaths worldwide, with half occurring in China. We aimed to synthesize existing evidence on stage-specific survival from this cancer in China to inform cancer control strategies.

Methods

English and Chinese literature databases were systematically searched to identify original research published up to May 31, 2019 that reported stage-specific survival from esophageal cancer in China. Two meta-analyses were performed using random-effects models to summarize stage-specific survival differences on relative and absolute scales. The number of esophageal cancer deaths that might have been prevented by early detection in China, in 2018, was estimated assuming 2 different downstaging scenarios.

Results

One hundred fifty eligible studies were identified, 97 had non-overlapping study populations (83,063 participants), 47 were included in the meta-analysis of hazard ratios, and 26 in the meta-analysis of survival probabilities. Late-stage (III-IV) was associated with 92% higher hazard of death compared with early-stage (0-II) (95% confidence interval 1.62-2.28), corresponding to an absolute 5-year survival difference of 31.2% (29.9%-32.4%). In all, 5.2% esophageal cancer deaths could have been prevented in China, in 2018, if the observed stage distribution at diagnosis (∼50% early-stage) was shifted to the real-life conditions of a population-based endoscopic screening program (∼60% early-stage) and 26.9% if shifted to that observed in the controlled setting of a randomized trial (∼90% early-stage).

Conclusion

Shifting downwards the stage distribution of esophageal cancer through screening would bring moderate reductions in mortality from the disease. Treatment improvements for early-stage patients are needed to reduce further mortality from this cancer.

D-Dimer: A Potential Solution to Problems of Cancer Screening, Surveillance, and Prognosis Assessment

Research has established a direct link between the plasma level of D-dimer and underlying malignancy. D-dimer has a strong association with the detection and prognosis of several cancers. For these reasons, this literature review aimed to evaluate the usefulness of elevated D-dimer levels in the initial screening of cancer, cancer recurrence surveillance, and for use as a cancer prognostic tool. A search of PubMed up to February 1, 2021, was carried out by reviewers. This literature review includes studies investigating the relationship between pretreatment plasma D-dimer levels and cancer. From the findings, pretreatment D-dimer levels can assist with cancer screening and prognosis assessment. Pretreatment plasma D-dimer levels can function as an effective cancer recurrence control. Elevated pre-treatment plasma D-dimer concentration is valuable in facilitating cancer screening, predicting an augmented risk of cancer recurrence, and anticipating a worse cancer prognosis.

Diagnostic Value of Serum D-Dimer for Detection of Gallbladder Carcinoma

Background

Previous studies have shown that D-dimer plays an essential role in the occurrence and development of various tumors, and its diagnostic value in gallbladder carcinoma (GBC) is unknown. Therefore, the purpose of our study was to explore the diagnostic value of D-dimer in distinguishing between gallbladder carcinoma and benign controls.

Methods

We retrospectively included age and gender-matched patients with gallbladder carcinoma and benign gallbladder lesions, and analyzed the diagnostic value of inflammatory markers, D-dimers, and tumor biomarkers by receiver operating characteristic curves (ROC).

Results

The area under the ROC curve of white blood cells (WBC), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), D-dimer, alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), and carbohydrate antigen 19–9 (CA19-9) were 0.600, 0.760, 0.729, 0.849, 0.502, 0.699, and 0.802, respectively. The combined diagnostic value of D-dimer and CA19-9 was 0.920, which was superior to other joint indicators.

Conclusion

Serum D-dimer may be considered as a potential biomarker for detection of GBC. Moreover, the combined diagnosis of D-dimer and CA19-9 has excellent diagnostic value in gallbladder carcinoma.

The Plasma Concentration of D-Dimer is Associated with Neoadjuvant-Chemotherapy Efficacy and the Prognosis in Osteosarcoma

PURPOSE

This retrospective study explored the clinical value of the plasma D-dimer level in osteosarcoma.

MATERIALS AND METHODS

We measured the plasma D-dimer level before neoadjuvant chemotherapy (D0) and the plasma D-dimer level after four courses of neoadjuvant chemotherapy (D1) in 103 patients with stage-IIB high-grade osteosarcoma of the limb. The change in the D-dimer level (ΔD) was defined as D1 minus D0. The chi-square test was used to compare categorical variables. Analyses of receiver operating characteristic (ROC) curves were undertaken to determine the optimal cutoff points for D0, D1, and ΔD. The area under the ROC (AUC) of D0, D1, and ΔD was calculated to evaluate their discriminatory abilities in monitoring the response to neoadjuvant chemotherapy (tumor necrosis). Survival curves were generated according to Kaplan-Meier analyses and compared using the Log rank test. Univariate analyses and multivariate analyses were carried out to determine independent prognostic factors.

RESULTS

Kaplan-Meier curves showed that a high D-dimer level at D0 and tumor diameter ≥8 cm were associated significantly with worse overall survival (OS) (P<0.05). Multivariate Cox regression analyses revealed a high D-dimer level at D0 (hazard ratio, 3.92; 95% confidence interval, 1.756-5.804; P=0.000) was an independent unfavorable prognostic factor. The chi-square test showed ΔD to be associated significantly with tumor necrosis. Analyses of ROC curves showed the D-dimer level at D0 and ΔD had better ability compared to that at D1 to discriminate the response to neoadjuvant chemotherapy.

CONCLUSION

The D-dimer level was correlated with the prognosis and response to chemotherapy in patients with stage-IIB high-grade osteosarcoma of the limb. The D-dimer level may serve as a risk factor of the response to chemotherapy and prognosis of localized osteosarcoma.

The significance of plasma D-dimer level in predicting high risk factors of endometrial cancer

Background

Activated clotting-fibrinolytic system is associated with poor outcome of cancer patients. This retrospective study aimed to evaluate the significance of plasma D-dimer level in predicting high risk factors of endometrial cancer (EC) patients.

Methods

Total 176 EC patients who underwent radiotherapy between January 2018 and June 2019 at Shanghai First Maternity and Infant Hospital were retrospectively analyzed. Their preoperative and postoperative plasma D-dimer levels were measured as routine assessment in our hospital, and analyzed for their association with clinicopathological data retrieved from medical records of the patients.

Results

High risk group had significantly higher 1st day postoperative D-dimer levels. The 1st day postoperative D-dimer predicted higher grade EC with the specificity of 63.7% and the sensitivity of 63.4%; predicted late stage EC with the specificity of 83.7% and the sensitivity of 58.6%; predicted deeper myoinvasion of EC with the specificity of 84.9% and the sensitivity of 43.3%; predicted lymphovascular space invasion positive EC with the specificity of 84.0% and the sensitivity of 50.0%; predicted lymph node metastasis of EC with the specificity of 50.9% and the sensitivity of 100%; and predicted cervical invasion of EC with the specificity of 82.1% and the sensitivity of 65.0%.

Conclusions

Increased postoperative plasma D-dimer levels accurately predicted high risk factors in patients with EC.

Plasma D-Dimer Levels are Elevated in Radiation Oncology Patients

D-dimer plasma levels were evaluated to determine whether they are altered by radiation. D-dimer levels were measured in radiation oncology patients, who were diagnosed with prostate, breast or lung cancer, or leukemia, as well as in healthy subjects serving as controls. Blood samples from radiotherapy patients were taken at three different time points: pre-, on- and post-radiotherapy. For the patients, considered together, differences between the D-dimer levels at these three time points compared to controls were statistically significant. Compared to the pre-radiotherapy measurements, radiation exposure was associated with a significant increase in the D-dimer levels at the on- and post-radiotherapy time points. At the post-radiotherapy time point, D-dimer levels in the patients were not significantly reduced compared to the on-radiotherapy levels, indicating that the risk for developing disseminated intravascular coagulation (DIC) may be increased in some radiation oncology patients. Of particular concern are the post-radiotherapy results observed for the D-dimer levels in the leukemia patients, in which the average fold increase in the D-dimer levels was 5.43 (compared to the pre-radiotherapy levels). These results suggest that leukemia patients might benefit from frequent assessment of their D-dimer levels after their total-body irradiation-conditioning regimen to detect early signs of DIC development. It is hoped that the results described here will lead to heightened awareness in the radiation oncology community that the risk of DIC development is greatly increased in some of these patients.

Prognostic value of osteopontin expression in esophageal squamous cell carcinoma: A meta-analysis

OBJECTIVE

To explore the prognostic role of osteopontin (OPN) overexpression in esophageal squamous cell carcinoma (ESCC).

METHODS

The PubMed, EMBASE, The Cochrane Library, China National Knowledge Infrastructure, Wanfang, Chinese Biomedical Data (CBM) and VIP databases were searched from the establishment dates of the databases to March 31, 2019, for potentially related studies. Stata 12.0 software was used for statistical analyses, and the hazard ratios (HRs) with 95% confidence intervals (CIs) were combined to assess the correlation of OPN overexpression with the overall survival (OS) and progression-free survival (PFS) of ESCC patients.

RESULTS

A total of 8 studies involving 811 patients from China or Japan were included. OPN overexpression was demonstrated to be significantly associated with poor OS (HR = 1.86, 95% CI: 1.22-2.83, P = 0.004), with high heterogeneity (I² = 61.2%, P = 0.012), and poor PFS (HR=1.63, 95% CI: 1.08-2.47, P = 0.020), without heterogeneity (I² = 0.0%, P = 0.839). Subgroup analysis results were similar to the pooled results.

CONCLUSION

OPN overexpression might serve as a promising independent prognostic risk factor in Chinese and Japanese ESCC patients. However, more well-designed studies enrolling more patients are still needed to verify our findings.

High pretreatment plasma D-dimer levels predict poor prognosis in gastrointestinal cancers: A meta-analysis

BACKGROUND

High pretreatment plasma D-dimer levels can predict poor prognosis in various types of gastrointestinal carcinomas. Our meta-analysis explored the correlation between plasma D-dimer levels and prognosis in gastrointestinal malignancies.

METHODS

Two independent reviewers conducted a comprehensive search from PubMed, ScienceDirect, Embase, Web of Science and the Cochrane Library. All articles evaluating the correlation between pretreatment plasma D-dimer levels and prognosis in gastrointestinal malignancies were searched. We chose overall survival (OS) as the primary survival outcome measure and progression-free survival (PFS), disease-free survival (DFS) and cancer-specific survival (CSS) as the secondary survival outcome measures. We extracted hazard ratios (HRs) and 95% confidence intervals (CIs) from the eligible publications.

RESULTS

We included 30 studies involving 5928 gastrointestinal cancer patients. There was an obvious correlation between high D-dimer levels and poor OS (HR = 2.01, 95% CI = 1.72-2.36, P < .01). High plasma D-dimer levels were correlated with shorter PFS (HR = 1.34, 95% CI = 1.05-1.70, P = .32), DFS (HR =  1.67, 95% CI = 1.12-2.50, P < .01) and CSS rates (HR = 1.93, 95% CI = 1.49-2.49, P = .66).

CONCLUSIONS

Elevated pretreatment plasma D-dimer levels might help predict poor prognosis in patients with gastrointestinal malignancies.

A combined marker based on plasma D-dimer and serum albumin levels in patients with nasopharyngeal carcinoma is associated with poor survival outcomes in a retrospective cohort study

Background: Activation of the clotting-fibrinolytic system in cancer patients is common and results in an unfavorable clinical outcome. This study aimed to investigate the role of pretreatment plasma D-dimer levels and the combination of D-dimer and albumin (DA) on the prediction of survival prognosis in patients with nasopharyngeal carcinoma (NPC). Methods: The study comprised 511 patients with NPC. Pretreatment plasma D-dimer and serum albumin levels were measured. DA was classified as a new biomarker where D-dimer and albumin levels were combined and was grouped by the cutoff value of both. The correlations of plasma D-dimer levels with clinicopathological features and survival outcome were calculated using the Chi-square test. Kaplan-Meier estimates were performed to analyze the survival functions and were compared using log-rank tests. Cox proportional hazard regression analysis was used to assess the effects of D-dimer and DA on distant overall survival (OS) and distant metastasis-free survival (DMFS). Results: The median follow-up period was 45.2 months (range 2.1-79.8). Elevated plasma D-dimer levels were positively associated with age at diagnosis (P = 0.034), platelet levels (P = 0.043), and Epstein Barr Virus (EBV) DNA copy number (P = 0.035). Additionally, multivariate analysis demonstrated that elevated plasma D-dimer levels were strongly associated with a poorer OS (HR 2.074, 95% CI 1.190-3.612, P = 0.010), but not DMFS. After adjustment for other variables, DA stratification acted as an independent prognostic marker for OS (P = 0.038) and DMFS (P = 0.031) in patients with NPC, when combined with albumin levels. Conclusions: Increased plasma D-dimer levels accurately predict poor OS and may be an effective independent prognostic factor in patients with NPC. Moreover, in conjunction with serum albumin, DA may serve as a factor in predicting OS and DMFS.

Prognostic Value of D-Dimer in Patients with Diffuse Large B-cell Lymphoma: A Retrospective Study

This study evaluated the significance of serum D-Dimer for predicting survival of patients with diffuse large B-cell lymphoma (DLBCL). We analyzed the clinical data from 113 patients who were newly diagnosed with DLBCL at Tongji Hospital from January 2012 to January 2016. The results indicated that there were higher levels of D-Dimer in DLBCL patients with the following characteristics: stage III/IV, lymphocyte monocyte ratio (LMR) <2.27, lactate dehydrogenase (LDH) > upper limit of normal (ULN), albumin (ALB) < 35 g/L, and anemia. After the first chemotherapeutic regimen, D-Dimer was significantly decreased concomitantly with LDH. Cox univariate regression analysis showed that the overall survival (OS) was negatively affected by the following factors: age > 60 years, stage III/W, LDH > ULN, LMR < 2.27, anemia and D-Dimer > 0.92. Multivariate analysis showed that only LDH > ULN (P=0.038) and age > 60 years (P=0.047) were independent adverse prognostic factors. However, it was suggested that D-Dimer could be regarded as a marker of high tumor burden and a potential prognostic screening tool for patients with DLBCL, not otherwise specified (NOS).

High pretreatment plasma D-dimer levels are associated with shorter overall survival in patients with small cell lung cancer

Objective

To investigate the relationship between pretreatment plasma D-dimer levels and survival in Chinese patients with small cell lung cancer (SCLC).

Methods

This retrospective study enrolled 82 patients with SCLC treated at Beijing Chaoyang Hospital, Capital Medical University, from January 2012 to January 2015. All patients were followed up. Associations between pretreatment plasma D-dimer levels measured by immunoturbidimetric assay and clinical outcomes were analyzed by Kaplan–Meier and multivariate analyses, using a cut-off level of 0.55 mg/L fibrinogen equivalent units (FEU).

Results

Median progression-free survival (PFS) and overall survival (OS) were significantly higher in patients with low D-dimer levels (≤0.55 mg/L FEU; 8.0 and 17.0 months, respectively) compared with patients with high levels (>0.55 mg/L FEU; 5.0 and 9.0 months, respectively). Plasma D-dimer levels, Karnofsky performance status, N stage, TNM stage, treatment, and neuron-specific enolase (NSE) levels were significantly associated with PFS, while D-dimer levels, N stage, TNM stage, and treatment were significantly associated with OS. Multivariate analysis revealed that TNM stage, treatment, and NSE levels were independently associated with PFS, while D-dimer levels and treatment were independently associated with OS.

Conclusions

Pretreatment plasma D-dimer levels were independently associated with OS in patients with SCLC.

D-dimer as a potential clinical marker for predicting metastasis and progression in cancer

D-dimer is a widely used biomarker for indicating the activation of coagulation and fibrinolysis, and is reported to serve important roles in cancer progression. The aim of the current retrospective study was to investigate the association of D-dimer plasma level with the development of various cancers. Patients with breast (n=86), gastric (n=317), pancreatic (n=37), colon (n=153) and rectal (n=137) cancers and 92 healthy volunteers were assessed in the present study. Plasma levels of D-dimer in the patients and healthy controls were measured by immunoturbidimetric assays. The association of D-dimer levels with the clinicopathological features of patients were also determined. The plasma levels of D-dimer were significantly higher in patients with breast cancer (P=0.0022), gastric cancer (P<0.0001), pancreatic cancer (P=0.0003), colon cancer (P=0.0001) and rectal cancer (P=0.0028), compared with the healthy controls. It was also determined that the plasma D-dimer levels were positively associated with clinical cancer stage (P<0.05) and metastasis (P<0.05). These findings suggested that the plasma D-dimer level may be used as marker for predicting cancer metastasis and progression.

Chaperonin-containing T‑complex protein 1 subunit 8 promotes cell migration and invasion in human esophageal squamous cell carcinoma by regulating α-actin and β-tubulin expression

The chaperonin-containing T‑complex protein 1 (CCT) has eight subunits, CCT 1-8, which are dysregulated in several types of cancer. To determine how subunit 8 (CCT8) influences the development of esophageal squamous cell carcinoma (ESCC), immunohistochemistry and western blot analysis were performed on 128 ESCC samples in the present study to measure the expression of CCT8. The prognostic value of CCT8 was analyzed using univariate and multivariate survival analyses. CCT8 knockdown in ESCC cells was performed and subsequently, the migration and invasion of ESCC cells was assessed. The results of immunohistochemistry and western blot analysis of ESCC tissue indicated that the expression of CCT8 in tumor tissues from patients with lymph node metastasis (LNM) was high whereas its expression in tissues from those without LNM was low. In addition, the overall survival rate of patients with high CCT8 expression was poor. It was demonstrated that CCT8 influenced the migration and invasion of ESCC cells by regulating α-actin and β-tubulin. Following CCT8 knockdown, cells were treated with cisplatin; it was demonstrated that α-actin and β-tubulin were downregulated and that cell apoptosis was enhanced. These data confirm that α-actin and β-tubulin are regulated by CCT8, and that increased CCT8 expression is associated with poor patient prognosis and cisplatin resistance in ESCC.

The prognostic value of D-dimer levels in endometrial cancer patients treated with intensity-modulated radiation therapy

Explain the important role of plasma D-dimer in cancers. Plasma D-dimer is increased in various tumors. However, the predictive value of plasma D-dimer is unclear. This study is aimed to evaluate the prognostic value of the D-dimer level in patients managed with intensity-modulated radiation for endometrial cancer. The D-dimer levels of forty patients with endometrial cancer were assessed before (D1) and after (D2) intensity-modulated radiation therapy (IMRT), respectively. The D-dimer level changes (ΔD) were defined as D2 minus D1. Cox regression and log-rank tests were used to evaluate the D-dimer levels in relation to progression free survival (PFS) and overall survival (OS). The OS and PFS of patients with a low D1 were significantly longer than those with a high D1 (P< 0.001, P< 0.001). We saw the similar correlation between D2, PFS and OS (P< 0.001, P< 0.001). Multivariate survival analyses showed that D-dimer was independently associated with OS and PFS in patients with endometrial cancer. The ΔD level was not related to the OS and PFS in endometrial cancer patients. The levels of D-dimer may be considered as an important predictor of PFS and OS in endometrial cancer patients treated with IMRT.
