Prognostic value of preoperative systemic inflammation response index in patients with oral squamous cell carcinoma: Propensity score-based analysis

Systemic Immune-Inflammatory Index and Other Inflammatory Marker Variations in Oral Squamous Cell Carcinoma Management

Background and Objectives: With the greatest rate of morbidity and death, OSCC is one of the world's most critical public health problems. Being a complex pathology, the management process that includes diagnostic, surgical, and adjuvant treatments must as well take into account the involvement of the immune system. This study aims to evaluate various biomarkers such as neutrophils, lymphocytes, platelets, SII, and NLR in the different stages of OSCC treatment and in correlation with TNM stages, in order to observe the inflammatory response of the host. Materials and Methods: A total of 154 patients diagnosed with OSCC were included in the present retrospective study. Routine blood samples were collected from all patients both before and after surgery. Using the detected values of platelets, neutrophils, and lymphocyte count, the systemic immune-inflammation index (SII) and neutrophil-to-lymphocyte ratio (NLR) were calculated. Based on the oncologist's recommendation, 46 patients underwent adjuvant radiotherapy as part of their oncologic treatment plan. For these patients, additional blood samples were collected before the first and after the last radiotherapy session for determining the values of platelets, neutrophils, and lymphocyte count, and SII and NLR calculation. Results: Prior to the first radiotherapy session, neutrophils decreased slightly to 4.35, lymphocytes increased to 2.23, and platelets rose to 258.62. The SII and NLR were 641.02 and 2.19, respectively. Following the last radiotherapy session, neutrophils increased substantially to 10.30, while lymphocytes decreased to 1.21. Platelets showed a slight reduction to 227.08. Notably, the SII rose dramatically to 3084.19, and the NLR increased significantly to 15.49, suggesting an important immune and inflammatory response of the host. Conclusions: The host's immunological and inflammatory responses are impacted by both surgery and adjuvant radiation administered following surgery. The parameters assessed-neutrophils, lymphocytes, platelets, SII, and NLR-qualify as significant variables that need to be monitored before, during, and following OSCC therapy. This study's findings validated significant changes in immunological and inflammatory markers in the management of OSCC.

The systemic inflammation response index as a risk factor for hepatic fibrosis and long-term mortality among individuals with metabolic dysfunction-associated steatotic liver disease

BACKGROUND AND AIMS

The systemic inflammation response index (SIRI) is associated with various diseases with inflammatory components, but its relationship with the progression of hepatic fibrosis and survival outcomes in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) is still unclear. This study was designed to investigate the potential associations between the SIRI and advanced hepatic fibrosis (AHF) as well as between the SIRI and long-term outcomes in individuals with MASLD.

METHODS AND RESULTS

A prospective cohort study was conducted using data gathered from the National Health and Nutrition Examination Survey (NHANES) spanning from 2005 to 2016. Weighted binary logistic regression, the Cox proportional hazards model, and time-dependent receiver operating characteristic (ROC) analyses were employed to assess the relationships among the SIRI, AHF, and mortality in patients with MASLD. Our study included a total of 5126 patients with MASLD. A higher SIRI was significantly associated with increased odds of AHF (OR 1.55, 95% CI 1.22, 1.96). According to the survival analyses, a higher SIRI was associated with greater all-cause (HR 1.19, 95% CI 1.15, 1.22) and cardiovascular mortality (HR 1.25, 95% CI 1.19, 1.32) after adjustment. The time-dependent ROC analysis indicated that the SIRI had a modest predictive value for discriminating MASLD individuals at higher versus lower mortality risk over 3-year, 5-year, and 10-year follow-up.

CONCLUSIONS

The SIRI is a promising tool for identifying MASLD individuals at risk of progressing to AHF and for predicting mortality outcomes.

Prognostic value of pretreatment lymphocyte percentage in oral cancer: A prospective cohort study

OBJECTIVE

To assess the prognostic role of pretreatment lymphocyte percentage (LY%) for patients with oral squamous cell carcinoma (OSCC).

METHODS

A large-scale prospective cohort study between July 2002 and March 2021 was conducted. Propensity score-matched (PSM) analysis and inverse probability of treatment weighting (IPTW) analysis were performed to adjust for potential confounders. Using random survival forest (RSF), the relative importance of pretreatment LY% in prognosis prediction was also assessed.

RESULTS

A total of 743 patients were enrolled and followed up (median: 2.75 years, interquartile range: 1.25-4.42 years). A high pretreatment LY% was significantly associated with better disease-specific survival of patients with OSCC (Hazard ratio [HR] = 0.60, 95% confidence interval [CI]: 0.42, 0.84). The same tendency was observed in PSM (HR = 0.57, 95% CI: 0.38, 0.85) and IPTW analysis (HR = 0.57, 95% CI: 0.40, 0.82). RSF showed that LY% ranked the fifth among importance ranking of all prognostic factors.

CONCLUSION

Pretreatment LY% showed a moderate predictive ability, suggesting it might be a valuable tool to predict prognosis for patients with OSCC.

Predictive value of systemic inflammatory response-related indices for survival in tongue cancer

OBJECTIVES

We assessed the potential prognostic significance of the preoperative systemic inflammation index, platelet-to-lymphocyte ratio, and neutrophil-to-lymphocyte ratio in patients who underwent surgical resection.

SUBJECTS AND METHODS

This retrospective study included 224 patients with clinicopathologically confirmed squamous carcinoma of the tongue who underwent surgery between August 2009 and December 2017. The optimal cut-off values for the indices were determined by receiver operating characteristic curves. Correlations between the indices and clinicopathological variables were determined by Pearson chi-square or Fisher exact tests. The Kaplan-Meier test was used to compare overall survival between groups (high and low values); the log-rank or Breslow test was used to assess differences in survival. Univariate and multivariate Cox regression models were used to analyze predictive values of the indices as independent indicators of overall survival. Bilateral p values of <0.05 were considered statistically significant.

RESULTS

Significant association was found between the indices and sex, tissue grade, tumor location, and lymph nodes metastases (p < 0.05). On Kaplan-Meier analysis, patients with lower values of the indices had longer overall survival (p < 0.05). Univariate and multivariate Cox regression models identified age, lymph node metastases, and neutrophil-to-lymphocyte ratio as independent predictors of overall survival.

CONCLUSION

The studied indices have potential prognostic significance in patients with squamous tongue cancer.

Assessment of aggregate index of systemic inflammation and systemic inflammatory response index in dry age-related macular degeneration: a retrospective study

Introduction

Inflammation is known to contribute to the development of age-related macular degeneration (AMD). Several inflammatory indices derived from routine complete blood counts have been proposed as biomarkers in multiple disorders.

Methods

In this study, clinical and laboratory data were retrospectively collected from medical records to assess the aggregate index of systemic inflammation (AISI) and the systemic inflammatory response index (SIRI) as potential biomarkers of systemic inflammation in patients with early diagnosis of dry AMD.

Results

The study included 90 patients with dry AMD and 270 age/sex-matched patients with cataracts as a control group. There were no significant differences in the AISI and SIRI results between the cases and controls (p = 0.16 and 0.19, respectively).

Conclusion

This suggests that AISI and SIRI may be inadequate metrics for AMD or lack sensitivity in detecting inflammatory changes. Exploring other routine blood markers may help to identify and prevent the early stages of AMD.

A novel inflammation-related prognostic biomarker for predicting the disease-free survival of patients with colorectal cancer

Background

To develop and evaluate the prognostic value of a comprehensive inflammatory biomarker for postoperative colorectal cancer (CRC) patients.

Methods

A total of 646 CRC patients were recruited between August 2017 and December 2019 from Fujian Medical University Union Hospital, with follow-up data up to 2021. The least absolute shrinkage and selection operator method (LASSO) was used to select inflammation indicators in order to construct a comprehensive biomarker (named NSAP). The Cox regression model was utilized to analyze the association between the NSAP and the disease-free survival (DFS) of CRC. Predictive performance and clinical utility of prognostic models were evaluated by area under the curve (AUC) and decision curve analyses (DCAs).

Results

During a median follow-up of 23 months, 95 clinical outcomes were observed, with a 1-year survival rate is 89.47%. A comprehensive inflammatory biomarker (NSAP) was established based on four blood indicators (including neutrophil-to-lymphocyte ratio (NLR), neutrophil×monocyte-to-lymphocyte ratio (SIRI), albumin-to-globulin ratio (AGR), and platelet-to-lymphocytes ratio (PLR)). Patients with a lower NSAP had significantly associated with better DFS of CRC (HR=0.53, 95%CI 0.32–0.89). Moreover, compared to a previously established model, the traditional TNM staging system or/and tumor markers, the nomogram based on NSAP displayed more excellent predictive ability (0.752 vs 0.597, 0.711 and 0.735, P < 0.05). DCAs also demonstrated that the established nomogram had better utility for decision making.

Conclusions

Our study suggests that NSAP may be a useful comprehensive prognostic biomarker for predicting the DFS of CRC patients. The nomogram based on NSAP can be considered a valuable tool to estimate the prognosis of patients with CRC.

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.

Systemic inflammatory response index as an independent risk factor for ischemic stroke in patients with rheumatoid arthritis: a retrospective study based on propensity score matching

OBJECTIVE

To investigate the relationship between systemic inflammatory response index (SIRI) and ischemic stroke (IS) in rheumatoid arthritis (RA) patients.

METHODS

Fifty-two RA patients with IS, who were admitted to Wujin Hospital Affiliated with Jiangsu University between 2015 and 2019, were selected as the study group, and 236 RA patients without IS were selected as the control group. Propensity score matching (PSM) function of SPSS 26.0 was used to carry out 1:1 propensity score matching for gender, age, blood pressure, blood glucose, blood lipid, and smoking history of patients in the two groups, and the caliper value was set as 0.02 to obtain covariate balanced samples between groups. When performing blood tests, the following are determined: rheumatoid factor (RF), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), mean platelet volume (MPV), calculated SIRI = (neutrophil × monocyte)/lymphocyte, and completed 28-joint disease activity score (DAS28-CRP). The differences in inflammatory markers between the two groups were compared, the independent risk factors were analyzed by logistic regression, and the auxiliary diagnostic value was evaluated by the receiver operating characteristic (ROC) curve.

RESULTS

A total of 48 pairs of patients were successfully matched. SIRI in the study group was higher than that in the control group (p < 0.05), and the mean platelet volume (MPV) was lower in the study group than in the control group (p < 0.05). SIRI, DAS28-CRP (r = 0.508, p < 0.01), ESR (r = 0.359, p < 0.05), and CRP (r = 0.473, p < 0.01) were positively correlated. Logistic regression analysis showed that SIRI was an independent IS risk factor in RA patients (odds ratio, 1.30; 95% confidence interval, approximately 1.008-1.678). The optimal threshold for SIRI-assisted diagnosis of patients with RA and IS was 1.62, the area under the ROC curve was 0.721 (p < 0.01), sensitivity was 54.17%, and specificity was 83.33%.

CONCLUSION

SIRI was independently associated with the occurrence of ischemic stroke in patients with RA. Thus, RA patients with elevated SIRI should be closely monitored. Key points • RA patients with IS had fewer traditional risk factors such as hypertension and diabetes, while inflammatory indicators were significantly increased. • The SIRI have drawn attention in recent years as novel non-specific inflammatory markers. However, only a few studies have been conducted to investigate their value in RA. • This study completes the gaps in the research on the relationship between SIRI and the risk of IS occurrence in RA patients.

A dynamic prognostic nomogram to predict the benefit from surgical treatment modality for patients with laryngeal squamous cell carcinoma

BACKGROUND

Although nonsurgical treatment strategy is increasingly adopted in patients with locoregionally advanced laryngeal squamous cell carcinoma (LSCC), survival disparities were reported between surgical treatment modality and organ preservation protocols, highlighting the great importance for accurate patients' selection.

METHOD

This secondary analysis used data from the Surveillance, Epidemiology, and End Results database between 2010 and 2015 with follow-up data up to 2018. We developed and validated a dynamic prognostic nomogram for overall survival (OS) in 4237 patients with LSCC and subgroup of 2087 patients with locoregionally advanced laryngeal squamous cell carcinoma (LALSCC). Based on the total risk score derived from the dynamic nomogram, two well-matched risk groups (i.e., low- and high-risk) were created via X-tile software and 1-to-1 propensity score matching (PSM); surgical treatment modality was compared with nonsurgical one in each risk group.

RESULTS

A more accurate and convenient dynamic prognostic nomogram based on age, marital status, T category, N category, M category, tumor size, and tumor differentiation was developed and validated, of which the predictive performance was superior to that of TNM staging system. For high-risk LALSCC selected by the dynamic nomogram, after 1-to-1 PSM, significantly improved OS was observed in patients with receiving surgical treatment compared to those receipt of nonsurgical management (restricted mean survival time at 36-month: 26.6 vs 22.7, p < 0.001; restricted mean survival time at 60-month: 36.7 vs 31.0, p = 0.003).

CONCLUSION

We establish and validate a more accurate and convenient dynamic prognostic nomogram for patients with LSCC, which may predict the benefit from surgical treatment modality for patients with high-risk LALSCC.

Systemic Inflammation Response Index (SIRI) Independently Predicts Survival in Advanced Lung Adenocarcinoma Patients Treated with First-Generation EGFR-TKIs

Background

Systemic inflammation response index (SIRI) has been reported to be an effective blood-based biomarker for predicting prognosis in various kinds of cancer patients. However, the prognostic role of SIRI in advanced lung adenocarcinoma patient remains unclear.

Methods

The aim of the present study is to evaluate the prognostic role of SIRI in EGFR-mutant advanced lung adenocarcinoma patients treated with first-generation EGFR-TKIs. A total of 245 patients who received gefitinib, erlotinib, or icotinib at the Second Xiangya Hospital were retrospectively evaluated. SIRI was defined as neutrophil count×monocyte/lymphocyte count. The optimal cut-off value was determined according to receiver operation characteristic curve analysis. Characteristics of patients were compared via chi-square test or Fisher’s exact test. Survivals were estimated by the Kaplan–Meier method and compared by the Log rank test. Multivariate analysis was estimated using the Cox proportional hazards model.

Results

It is showed that high SIRI was associated with male patient, smoker, worse ECOG PS, 19-DEL mutation. Kaplan–Meier survival analysis showed that ECOG PS, brain metastasis, SIRI were significantly correlated with progression-free survival (PFS), and gender, ECOG PS, brain metastasis, NLR and SIRI were significantly correlated with overall survival (OS). Multivariate analysis showed that SIRI and ECOG PS independently predict PFS and OS.

Conclusion

Our findings indicate that SIRI is an effective and convenient marker for predicting prognosis in advanced EGFR-mutant lung adenocarcinoma patients treated with first-generation TKI.

The Clinical Impacts of Pretreatment Peripheral Blood Ratio on Lymphocytes, Monocytes, and Neutrophils Among Patients with Laryngeal/Hypopharyngeal Cancer Treated by Chemoradiation/Radiation

Purpose

This study aimed to investigate the clinical impacts of the pretreatment peripheral blood ratios of lymphocytes, monocytes and neutrophils among patients with hypopharyngeal cancer/laryngeal cancer.

Patients and Methods

A total of 141 people with cases of hypopharyngeal cancer/laryngeal cancer were enrolled to evaluate the clinical impacts of the systemic inflammation response index (SIRI), neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR) in pretreatment blood among patients with laryngeal/hypopharyngeal cancer between January 2012 and December 2014.

Results

Those patients with higher pretreatment LMR (>2.99) showed a significantly higher 5-year complete response rate (CR) (69% vs 31%) than those with lower LMR (≤2.99, p = 0.006). Additionally, those patients with lower pretreatment SIRI (<3.26) showed a significantly higher 5-year CR (90% vs 10%) than those with higher SIRI (≥3.26, p < 0.001). Patients with higher LMR had better 5-year overall survival (OS) (p = 0.01) and 5-year progression-free (PFS) (p = 0.005) rates than those with lower LMR in univariate analysis. Patients with lower SIRI had better 5-year OS (p < 0.001) and 5-year PFS (p < 0.001) than those with higher SIRI in univariate analysis. In the Cox regression analysis, SIRI (HR = 1.941, [95% CI: 1.223-3.081], p = 0.005) and N classification (HR = 2.203, [95% CI: 1.327-3.657], p = 0.002) were independent variables of 5-year OS. In addition, SIRI (HR= 2.127, [95% CI: 1.214-3.725], p = 0.008), T classification (HR = 2.18, [95% CI: 1.072-4.433], p = 0.031), and N classification (HR = 2.329, [95% CI: 1.395-3.889], p = 0.001) were independent variables of 5-year PFS.

Conclusion

Pretreatment SIRI is superior to LMR in predicting treatment response and clinical outcomes among patients with laryngeal/hypopharyngeal cancer treated by CRT/RTO. SIRI may be adopted in the treatment of laryngeal/hypopharyngeal cancer by CRT/RTO.
