Abstract:
Objective To investigate the prognostic value of peripheral blood neutrophil-lymphocyte ratio(NLR)and thioredoxin reductase(TrxR)in patients with ovarian cancer receiving immunotherapy.Methods A total of 109 patients with advanced ovarian cancer treated in the Tumor Hospital Affiliated to Nantong University from January 2021 to December 2021 were selected as the research objects.The levels of NLR and TrxR in peripheral blood before immunotherapy were detected,and the evaluation value of NLR and TrxR on short-term efficacy,progression-free survival(PFS)and overall survival(OS)in ovarian cancer pa-tients receiving immunotherapy was explored.Results The optimal cut-off values of TrxR and NLR were 4.97 U/mL and 2.49%,respectively.According to the optimal cut-off value of TrxR and NLR,the patients were divided into the high level of TrxR group(69 cases,≥4.97 U/mL)and the low level of TrxR group(40 cases,<4.97 U/mL),the high level of NLR group(72 cases,≥2.49%)and the low level of NLR group(37 cases,<2.49%).The objective response rate(ORR)of the high level of NLR group was lower than that of the low level NLR group(P<0.05),and the disease progression rate(DPR)was higher than that of the low NLR group(P<0.05).The high level of TrxR group had a significantly lower ORR and a significantly higher DPR than the low level of TrxR group(P<0.05).The median PFS and OS of the high level of NLR group were 15.0 months and 16.0 months,respectively.The median PFS and OS of the low level of NLR group were 19.0 months and 21.0 months,respectively.The median PFS and OS of the high level of TrxR group were 15.0 months and 17.0 months,respectively.The median PFS was 18.0 months and the median OS was 21.0 months in the low level of TrxR group.NLR and TrxR were the influencing factors of PFS and OS in pa-tients with ovarian cancer immunotherapy(P<0.05).Conclusion The levels of NLR and TrxR in peripheral blood can be used as important prognostic indicators for advanced ovarian cancer patients receiving immuno-therapy.The lower the levels of NLR and TrxR,the better the prognosis of ovarian cancer patients.
