Abstract 4533
Background
LIPI, based on derived NLR (neutrophils/(leucocytes-neutrophils)) and lactate dehydrogenase (LDH) level, has been correlated to ICI outcomes in advanced non small cell lung cancer. We evaluated if HN-LIPI could offer the same role in R/M SCCHN.
Methods
This is a multicentric (9 European centers) retrospective study including R/M SCCHN patients (pts) treated with ICI from September 2014 to May 2019 and a control cohort (N = 83) only treated with chemotherapy. Baseline biological and clinicaldata were collected from medical records. According to dNLR>3 and LDH > upper limit of normal, HN-LIPI defines 3 groups (Good: 0 factor; Intermediate: 1 factor; Poor: 2 factors).The primary endpoint was overall survival (OS), and secondary endpoints was progression free survival (PFS).
Results
We included 273 pts (84% male, 84% smokers and 87% with PS ≤ 1, median age 59 years). Primary tumor locations were: oropharynx (37%), oral cavity (23%) and hypopharynx (17%). p16by immunohistochemistry was positive in 33% oropharynx pts. ICI were administered in 53% of patients as monotherapy and in 47% in combination. The median number of prior lines was 2 (1-7) with 65% of pts receiving ≥2. Median follow up of 13.2 months (mo).The median (m) PFS and OS were 2.84 mo [2.53-3.52] and 11.8mo [9.4-15.8]. dNLR >3 was associated to poor OS(HR 1.6, 95%CI: 1.1-2.3) but not with PFS (p = 0.11). LDH was not associated with endpoints. Median OS for good, intermediate and poor LIPI groups were: 15.9mo, 8.9mo and 6.2mo, respectively (p=.03). In univariate analysis, Intermediate and Poor risk groups were associated with OS (HR:1.5 95%CI:1.1-2.2 and HR:2 95%CI:1.0-4. respectively ). There was trend to better objective response rate in the good risk group compared with intermediate and poor (36%, 22% and 18%, p = 0.09).
Conclusions
Baseline HN-LIPI is associated with worse OS for ICI in R/M SCCHN but not with PFS. Control cohort results and multivariate models will be further presented at the congress, which would elucidate the prognostic and/or predictive impact in R/M SCCHN population.
