Correlation Between Natural Killer Cell Activity and Systemic Inflammatory Markers for Heterogeneous Cancer Patients Treated With Wheel Balance Cancer Therapy

Abnormal pretreatment coagulation factor levels correlate with poor prognosis in patients with early-stage extranodal nasal-type natural/killer T cell lymphoma

Coagulative dysfunction is frequently observed among patients with extranodal nasal-type natural killer/T cell lymphoma (NKTCL) in our clinical practice. However, the true prognostic value of coagulation factors in patients with NKTCL has not been evaluated systemically. Data for patients with stage I/II NKTCL who were treated in the Cancer Hospital, Chinese Academy of Medical Sciences, from January 2008 to January 2019 were collected retrospectively. The patients enrolled in this study were initially diagnosed as having early-stage disease. The patients' baseline characteristics and pretreatment laboratory tests for coagulation function, including fibrinogen (FIB) and D-dimer (D-D), were reviewed and analyzed. The influence of coagulative factors on the responses and prognosis of patients with early-stage NKTCL was evaluated. Among 394 patients assessed, 154 were included in this study. Abnormal coagulation function was found in nearly half of the patients (48.1%). Univariate analysis showed that reduced complete remission (CR) was associated with elevated D-D (P = 0.001) and elevated FIB levels (P = 0.006). The D-D level was demonstrated as associated with unfavorable progression-free survival (PFS) (P = 0.003) and overall survival (OS) (P = 0.002). Multivariate analysis indicated that an elevated D-D level was an independent factor for poor clinical response (P = 0.019), PFS (P = 0.046), and OS (P = 0.024). Elevated pretreatment levels of coagulation factors, especially D-D and plasma FIB, are unfavorable predictors for clinical response, OS, and PFS in early-stage NKTCL.
