Systemic immune-inflammation index (SII), based on peripheral lymphocyte, neutrophil, and platelet counts, was recently investigated as a prognostic marker in several tumors. However, SII has not been reported in esophageal squamous cell carcinoma (ESCC). We evaluated the prognostic value of the SII in 916 patients with ESCC who underwent radical surgery. Univariate and multivariate analyses were calculated by the Cox proportional hazards regression model. The time-dependent receiver operating characteristics (ROC) curve was used to compare the discrimination ability for OS. PSM (propensity score matching) was carried out to imbalance the baseline characteristics. Our results showed that SII, PLR, NLR and MLR were all associated with OS in ESCC patients in the Kaplan-Meier survival analysis. However, only SII was an independent risk factor for OS (HR = 1.24, 95% CI 1.01–1.53, P = 0.042) among these systemic inflammation scores. The AUC for SII was bigger than PLR, NLR and MLR. In the PSM analysis, SII still remained an independent predictor for OS (HR = 1.30, CI 1.05–1.60, P = 0.018). SII is a novel, simple and inexpensive prognostic predictor for patients with ESCC undergoing radical esophagectomy. The prognostic value of SII is superior to PLR, NLR and MLR.
In advanced NSCLC patients, CAR may be a better predictor of prognosis compared with other inflammatory markers. A prospective multicenter study is needed to verify these findings.
Aim: We aimed to explore the effect of long noncoding RNA HCG18 in colorectal cancer (CRC). Materials & methods: Relative gene and protein expression were screened. Colony formation and flow cytometry assays were performed to determine proliferation and apoptosis. Dual luciferase assay and RNA immunoprecipitation assay were conducted to validate the interaction between indicated molecules. Xenograft in nude mice was applied to verify the conclusion in vivo. Results: HCG18 and PD-L1 were upregulated while miR-20b-5p was downregulated in CRC tissue. Functional analysis revealed that lncRNA HCG18 promoted proliferation, migration and resistance to cetuximab of CRC cells via miR-20b-5p/PD-L1 axis. Conclusion: HCG18 facilitated the progress of tumor, conferred to cetuximab resistance and suppressed CD8+ T cell via miR-20b-5p/PD-L1 axis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
