The correlation between hemostatic parameters and mortality rate in patients with non-small cell lung cancer

The increasing level of hemostatic parameters and tumor markers were associated with cancer progression and poor prognosis, particularly in NSCLC. The objective of this study is to determine whether there was a correlation between hemostatic parameters and mortality rate in patients with NSCLC. This was a prospective analytical study with a pretest-posttest design which included 41 patients with diagnosis of NSCLC. Plasma levels of PT, APTT, Ti', D-dimer, and fibrinogen were measured before initiation of chemotherapy and remeasured after 4 cycles or 6 cycles of chemotherapy, based on the clinical condition of patients. Then, patients were followed up for 1 year to evaluate the mortality rate. The majority of subjects were male (85.4%) with adenocarcinoma (75.6%). There was no significant difference in mean between adenocarcinoma and squamous cell carcinoma (P>0.05). Most patients died after one month of follow up (61%). The parameters which could predict high mortality rate in NSCLC were prolonged PT and the increased of D-dimer with RR> 1 , although they had not significant in statistical analysis (P>0.05). There is no correlation between hemostatic parameters and mortality rate in patients with NSCLC.
