Abstract Background Currently there are no recognized or validated biomarkers to identify HCC patients(pts) likely to benefit from N. Several studies have established the inverse relationship between inflammation-based scores such as NLR, PLR and survival in other solid tumours treated with immunotherapy. We evaluated the relationship between NLR and PLR and survival outcomes in HCC pts treated with N at Mount Sinai Hospital. Methods One hundred and four HCC pts treated between June 2016 and July 2018 were identified. NLR=Absolute neutrophil count/ Absolute lymphocyte count (ALC) and was calculated pretreatment and at 6-8 weeks after 3 doses (Posttreatment) of N. PLR=Platelet count/ALC. Kaplan-Meier analysis and the log-rank test were used to calculate and compare Overall and Progression free survival (OS, PFS) between NLR Results Median age was 66 (29-89) years. Median treatment duration was 26 (2-149) weeks. Child Pugh score (CPS, N = 96) was A in 64 (66%) and B in 32 (33%) pts. Barcelona Clinic Liver Cancer (BCLC) stage was B in 21 (20%) and C in 83 (80%) pts. Median follow-up time was 17 months (95% CI (15.7, 20.7). NLR was Table . 744P Pretreatment PLR group N(%) OS (months) 36(36) 35 P = 0.0495 > = 119 & 32(31) 10 > = 224 33(33) 15 Post treatment PLR group 35(35) Not Reached P = 0.0126 > = 126 & 31(31) 19 > = 229 33(33) 10 Conclusions This study suggests that lower NLR and PLR levels may predict better survival outcomes in HCC patients treated with N. The potential role of NLR and PLR as early predictors of immunotherapy outcomes in HCC pts warrants further evaluation. Legal entity responsible for the study Mount Sinai Hospital.
