Abstract

Aims

Investigate the role of pretreatment Lung Immune Prognostic Index (LIPI) as biomarker in PDL1≥50% NSCLC patients receiving pembrolizumab.

Patients and methods

We retrospectively identified 117 patients, divided into 3 prognostic groups according to LIPI score. For each patient we evaluated 1-year overall survival (OS) and progression free survival (PFS) rate. C-statistic and survival ROC curves were used to study discrimination of LIPI.

Results

After a median follow-up of 11.7 months, 1-year OS rate was 60.1%, 35.3% and 28.6%, while 1-year PFS rate was 39.1%, 20.6% and 14.3% in good, intermediate and poor LIPI groups, respectively (p<0.001). The c-statistic and AUC of LIPI were 0.63 and 0.662 for OS and 1-year OS, respectively.

Conclusions

Higher LIPI score is related to worse survival in advanced NSCLC patients treated with first-line pembrolizumab. However, based on c-statistic and AUC, LIPI does not represent a good prognostic survival model.
