The lesson to take from the findings of this study is the need for regular monitoring of serum albumin and D-dimer levels in lung cancer patients who have PE. In fact, a recent systematic review and meta-analysis identified D-dimer level as an independent predictor of poor prognosis in patients with lung cancer; high plasma D-dimer level leads to lower survival than in the low D-dimer level [25]. Here, ALB is linked to lung carcinoma.
