The effect of systemic inflammation indexes and 18FDG PET metabolic parameters on survival in advanced lung adenocarcinoma

Prognostic role of systemic inflammation response index in patients with non-small cell lung cancer: a meta-analysis

OBJECTIVES

The significance of the systemic inflammation response index (SIRI) for predicting prognostic outcomes in patients with non-small cell lung cancer (NSCLC) has been analysed in previous studies, but no consistent conclusions have been obtained. Consequently, the present meta-analysis was performed to identify the significance of SIRI in predicting the prognosis of NSCLC.

DESIGN

This study followed the PRISMA guidelines.

DATA SOURCES

PubMed, Web of Science and Embase databases were searched between their inception and 26 November 2023.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Studies investigating the relationship between SIRI and survival outcomes of patients with NSCLC were included.

DATA EXTRACTION AND SYNTHESIS

The value of SIRI in predicting prognosis in NSCLC cases was predicted using combined hazard ratios (HRs) and 95% CIs.

RESULTS

Nine articles with 3728 cases were enrolled in this study. Based on our combined data, a higher SIRI value was markedly linked with poor overall survival (OS) (HR=2.08, 95% CI 1.68 to 2.58, p<0.001) and inferior progression-free survival (PFS) (HR=1.74, 95% CI 1.47 to 2.07, p<0.001) of NSCLC. According to the subgroup analysis, country, history and cut-off value did not affect the significance of SIRI in predicting OS and PFS in NSCLC (p<0.05).

CONCLUSIONS

A higher SIRI value was significantly associated with both OS and PFS in patients with NSCLC. Moreover, SIRI had a stable prognostic efficiency for NSCLC in various subgroups.

Systemic Inflammation Response Index as a Prognostic Marker in Cancer Patients: A Systematic Review and Meta-Analysis of 38 Cohorts

Background

The systemic inflammation response index (SIRI), a novel and cost-effective serum biomarker, is associated with prognosis in patients with cancer. However, the prognostic value of the SIRI in cancer remains unclear. This study aimed to evaluate the potential role of the SIRI as a prognostic indicator in cancer.

Methods

Reports in which the prognostic value of the SIRI in cancer was evaluated were retrieved from electronic databases. The pooled hazard ratio (HR) and 95% confidence interval (CI) were calculated to evaluate the prognostic significance of the SIRI. The odds ratio (OR) was also calculated to explore the association between the SIRI and clinicopathological features.

Results

This study included 30 retrospective studies with 38 cohorts and 10 754 cases. The meta-analysis indicated that a high SIRI was associated with short overall survival (OS) (HR = 2.04, 95% CI = 1.82-2.29, P < .001) and disease-free survival (DFS)/recurrence-free survival (RFS)/progression-free survival (PFS) (HR = 2.08, 95% CI = 1.84-2.34, P < .001). Subgroup analysis showed that the prognostic value of the SIRI was significant in all kinds of cancer included. Moreover, the SIRI was significantly correlated with sex, tumor size, T stage, N stage, TNM stage, and lymphovascular invasion.

Conclusion

The pretreatment SIRI could be a promising universal prognostic indicator in cancer.
