Objective: The present study compared the prognostic value of the Glasgow prognostic score (GPS), modified GPS (mGPS), high-sensitivity mGPS (HS-mGPS), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), prognostic index (PI), and prognostic nutritional index (PNI) in patients with resectable non-small cell lung cancer (NSCLC).
Materials and methods: This retrospective study included 327 consecutive patients with resectable NSCLC with a follow.-up period. >5. years. Initially, the HS-mGPS was directly compared with the GPS and mGPS in terms of their ability to predict survival in patients with resectable NSCLC. Second, inflammation.-based scores, including the HS-mGPS, NLR, PLR, PI, and PNI, were analyzed preoperatively using multivariate Cox analysis. Clinical characteristics reflecting cancer progression were also analyzed.
Results: Elevated GPS (P < 0.001), mGPS (P < 0.001), and HS-mGPS (P < 0.001) levels were associated with reduced overall survival. The HS-mGPS (P < 0.001) was superior to the GPS and mGPS (P = 0.884) as a prognostic marker of postoperative outcomes. On multivariate Cox analysis, age (P = 0.026), p-T status (P < 0.001), p-N status (P < 0.001), lymphatic vessel invasion (P = 0.008), and the HS-mGPS (P = 0.016) were independent prognostic factors for survival.
Conclusion: These results suggest that the HS-mGPS might have a greater prognostic impact than the GPS, mGPS, NLR, PLR, PI, or PNI in patients with resectable NSCLC.
