Article Synopsis
  • This study explores the relationship between pretreatment serum lipoprotein(a) [Lp(a)] levels and EGFR gene mutations in patients with advanced lung adenocarcinoma undergoing treatment with EGFR-TKIs.
  • The research evaluated 338 patients and concluded that a higher Lp(a) level (above 20.48 mg/L) is linked to a lower rate of EGFR mutations (48.0% vs 65.5%).
  • The findings also indicate that higher Lp(a) levels are associated with longer progression-free survival (16.1 months vs 9.6 months), suggesting it is a significant independent predictor for both EGFR mutations and PFS.
