Activation of coagulation and fibrinolysis has been observed in many tumors. Our study aimed to investigate the clinical and prognostic significance of various plasma coagulation tests in patients with cervical cancer. A total of 296 patients with cervical cancer were included in the analysis. Patients were followed up for at least 60 months until death. Pretreatment parameters including activated partial thromboplastin time, D-dimer, fibrinogen, prothrombin time, thrombin time, lactate dehydrogenase, and squamous cell carcinoma antigen were evaluated. Prothrombin time (hazard ratio = 1.825; P = 0.006) and plasma D-dimer levels (hazard ratio = 2.179; P = 0.036) were identified as significant independent predictors of overall survival. Patients with elevated D-dimer levels had a significantly shorter overall survival compared with those with low-D-dimer levels (<0.5 μg/ml) in the stage I subgroup (n = 98, P = 0.019) and stage II subgroup (n = 77, P = 0.044). D-dimer levels differed significantly according to mortality (P < 0.001), stage I versus stage II (P = 0.030), and stage I versus stage III/IV (P = 0.038). DD level of patients with chemotherapy and/or radiotherapy was higher than patients with other treatment (P < 0.001). Patients with a low-D-dimer level (<0.5 μg/ml) showed a significantly better 5-year overall survival (OS) compared with patients with an increased D-dimer level for different histological typing of squamous cell carcinoma (SCC) (P = 0.001) and non-SCC (P < 0.043). In conclusion, the pretreatment plasma D-dimer level is a potential prognostic factor for cervical cancer.

Studies have found that lymphoma patients often exhibit abnormal lipid metabolism, and a decrease in serum high-density lipoprotein cholesterol (HDL-C) may occur during lymphomagenesis and tumor growth. However, no literatures have investigated the role of HDL-C in patients with extranodal natural killer/T cell lymphoma (ENKTL). In this study, we retrospectively reviewed the HDL-C level in 107 patients newly diagnosed with ENKTL that received either l-asparaginase-based regimen or EPOCH regimen as induction chemotherapy, and evaluated its prognostic value. The mean level of HDL-C was 1.10 mmol/L (range, 0.15–2.63), and the HDL-C level was significantly lower in patients with elevated LDH and beta 2-microglobulin (β2-MG) (p = 0.017 and 0.001, respectively) and those who underwent disease progression and died (p = 0.031 and 0.007, respectively). In univariate survival analysis, higher Eastern Cooperative Oncology Group performance status score (≥1), Ann Arbor stage III–IV, elevated LDH, higher international prognostic index (IPI) score (≥2 vs. 1 vs. 0), decreased HDL-C level (<40 mg/dL), elevated β2-MG level, and response status after induction chemotherapy correlated significantly with poor progression-free survival (PFS) and overall survival (OS) (p < 0.05). In a multivariate Cox regression model that included IPI score, HDL-C level, β2-MG level, and response status after induction chemotherapy, it was found that HDL-C level and response status after chemotherapy were independent prognostic factors for OS (p = 0.014 and 0.010, respectively) and PFS (p = 0.016 and 0.020, respectively). In conclusion, HDL-C was found to be a valuable independent prognostic factor in ENKTL, and the mechanism needs to be further investigated, which may offer the possibility of therapeutic targets.
