Neutrophil to lymphocyte ratio and albumin bilirubin grade in hepatocellular carcinoma: A systematic review

摘要

BACKGROUND Hepatocellular carcinoma(HCC)is a frequent cause of cancer related death globally.Neutrophil to lymphocyte ratio(NLR)and albumin bilirubin(ALBI)grade are emerging prognostic indicators in HCC.AIM To study published literature of NLR and ALBI over the last five years,and to validate NLR and ALBI locally in our centre as indicators of HCC survival.METHODS A systematic review of the published literature on PubMed of NLR and ALBI in HCC over the last five years.The search followed the guidelines of the preferred reporting items for systematic reviews and meta-analyses.Additionally,we also investigated HCC cases between December 2013 and December 2018 in our centre.RESULTS There were 54 studies describing the relation between HCC and NLR and 95 studies describing the relation between HCC and ALBI grade over the last five years.Our local cohort of patients showed NLR to have a significant negative relationship to survival(P=0.011).There was also significant inverse relationship between the size of the largest HCC nodule and survival(P=0.009).Median survival with alpha fetoprotein(AFP)10 KU/L was 5 mo.We found that AFP was inversely related to survival,this relationship was not statically significant(P=0.132).Mean survival for ALBI grade 1 was 37.7 mo,ALBI grade 2 was 13.4 months and ALBI grade 3 was 4.5mo.ALBI grades performed better than Child Turcotte Pugh score in detecting death from HCC.CONCLUSION NLR and ALBI grade in HCC predict survival better than the conventional alpha fetoprotein.ALBI grade performs better than Child Turcotte Pugh score.These markers are done as part of routine clinical care and in cases of normal alpha fetoprotein,these markers could give a better understanding of the patient disease progression.NLR and ALBI grade could have a role in modified easier to learn staging and prognostic systems for HCC.
