Diagnostic value and therapeutic efficacy of serum levels of pro-gastrin-releasing peptide precursor (ProGRP) and neuron-specific enolase (NSE) in patients with lung cancer

The tumour markers ProGRP and NSE levels are of paramount significance for the clinical diagnosis and staging of SCLC patients. ProGRP is a more specific and sensitive tumour marker for SCLC than NSE and can be employed as an auxiliary diagnostic tool for SCLC. Thus, it is worth promoting ProGRP in a clinical setting.
