However, it has been shown for blood plasma that prognostic ones may be AFR (the albumin/fibrinogen ratio) for non-small cell lung cancer (NSCLC) [95], LDH for both NSCLC and SCLC [96,97], AAPR (albumin/alkaline phosphatase ratio) [98], the level of Cyfra 21-1 [99], the content of selenium [100], among others. This evidence concerns the gene ALB and small cell lung carcinoma.
