Research Progress of Systemic Immune Inflammatory Index in Prostate Cancer

Prostate cancer has gradually risen to become the second most common cancer threatening men’s health, and prostate-specific antigen (PSA), as the main screening indicator for prostate cancer, has the defects of low specificity and insufficient diagnostic efficacy. As a novel inflammatory index based on neutrophil, lymphocyte and platelet counts, the systemic immune-inflammation index (SII) has recently become a more powerful biomarker for predicting the occurrence and progression of various malignancies. SII reflects the systemic inflammatory response of prostate cancer patients in a more balanced manner, and has higher predictive value than neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). High SII values are often associated with cancer progression and poor prognosis. This article reviews the research progress of SII in prostate cancer, in order to provide guidance for clinical practice.

Correlation between preoperative systemic immune inflammation index, nutritional risk index, and prognosis of radical resection of liver cancer

BACKGROUND Radical surgery is the most commonly used treatment for hepatocellular carcinoma(HCC).However,the surgical effect remains not ideal,and prognostic evaluation is insufficient.Furthermore,clinical intervention is rife with uncertainty and not conducive to prolonging patient survival.AIM To explore correlations between the systemic immune inflammatory index(SII)and geriatric nutritional risk index(GNRI)and HCC operation prognosis.METHODS This retrospective study included and collected follow up data from 100 HCC.Kaplan–Meier survival curves were used to analyze the correlation between SII and GNRI scores and survival.SII and GNRI were calculated as follows:SII=neutrophil count×platelet count/lymphocyte count;GNRI=[1.489×albumin(g/L)+41.7×actual weight/ideal weight].We analyzed the predictive efficacy of the SII and GNRI in HCC patients using receiver operating characteristic(ROC)curves,and the relationships between the SII,GNRI,and survival rate using Kaplan–Meier survival curves.Cox regression analysis was utilized to analyze independent risk factors influencing prognosis.RESULTS After 1 year of follow-up,24 patients died and 76 survived.The area under the curve(AUC),sensitivity,specificity,and the optimal cutoff value of SII were 0.728(95%confidence interval:0.600-0.856),79.2%,63.2%,and 309.14,respectively.According to ROC curve analysis results for predicting postoperative death in HCC patients,the AUC of SII and GNRI combination was higher than that of SII or GNRI alone,and SII was higher than that of GNRI(P<0.05).The proportion of advanced differentiated tumors,tumor maximum diameter(5–10 cm,>10 cm),lymph node metastasis,and TNM stage III-IV in patients with SII>309.14 was higher than that in patients with SII≤309.14(P<0.05).The proportion of patients aged>70 years was higher in patients with GNRI≤98 than that in patients with GNRI>98(P<0.05).The 1-year survival rate of the SII>309.14 group(compared with the SII≤309.14 group)and GNRI≤98 group(compared with the GNRI>98 group)was lower(P<0.05).CONCLUSION The prognosis after radical resection of HCC is related to the SII and GNRI and poor in high SII or low GNRI patients.

Prognostic impact of preoperative nutritional and immune inflammatory parameters on liver cancer

The immune response to tissue damage or infection involves inflammation,a multifaceted biological process distinguished by immune cell activation,mediator secretion,and immune cell recruitment to the site of injury.Several blood-based immune-inflammatory biomarkers with prognostic significance in malignancies have been identified.In this issue of the World Journal of Gastrointestinal Surgery,they examined the prognosis of liver cancer radical resection in relation to pre-operative systemic immune-inflammation and nutritional risk indices.Comparing older and younger individuals often reveals compromised nutritional and immu-nological statuses in the former.Therefore,performing preoperative evaluations of the nutritional status and immunity in geriatric patients is critical.In addition to being a primary treatment modality,radical resection is associated with a sig-nificant mortality rate following surgery.Insufficient dietary consump-tion and an elevated metabolic rate within tumor cells contribute to the increased proba-bility of malnutrition associated with the ailment,consequently leading to a sub-stantial deterioration in prognosis.Recent studies,reinforce the importance of nu-tritional and immune-inflammatory biomarkers.Prior to surgical intervention,geriatric nutritional risk and systemic immune-inflammatory indices should be prioritized,particularly in older patients with malignant diseases.

Prognostic value of preoperative prognostic nutritional index and its associations with systemic inflammatory response markers in patients with stage Ⅲ colon cancer

Background: The prognostic nutritional index(PNI) has been widely applied for predicting survival outcomes of patients with various malignant tumors. Although a low PNI predicts poor prognosis in patients with colorectal cancer after tumor resection, the prognostic value remains unknown in patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy. This study aimed to investigate the prognostic value of PNI in patients with stage III colon cancer.Methods: Medical records of 274 consecutive patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy with oxaliplatin and capecitabine between December 2007 and December2013 were reviewed. The optimal PNI cutoff value was determined using receiver operating characteristic(ROC) curve analysis. The associations of PNI with systemic inflammatory response markers, including lymphocyte-to-monocyte ratio(LMR), neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), and C-reactive protein(CRP)level, and clinicopathologic characteristics were assessed using the Chi square or Fisher's exact test. Correlation analysis was performed using Spearman's correlation coefficient. Disease-free survival(DFS) and overall survival(OS)stratified by PNI were analyzed using Kaplan-Meier method and log-rank test, and prognostic factors were identified by Cox regression analyses.Results: The preoperative PNI was positively correlated with LMR(r= 0.483, P < 0.001) and negatively correlated with NLR(r =-0.441, P < 0.001), PLR(r =-0.607, P < 0.001), and CRP level(r =-0.333, P < 0.001). A low PNI(≤49.22)was significantly associated with short OS and DFS in patients with stage ⅢC colon cancer but not in patients with stage ⅢA/ⅢB colon cancer.In addition, patients with a low PNI achieved a longer OS and DFS after being treated with6-8 cycles of adjuvant chemotherapy than did those with < 6 cycles. Multivariate analyses revealed that PNI was independently associated with DFS(hazard ratios 2.001; 95% confidence interval 1.157-3.462; P = 0.013).Conclusion: The present study identified preoperative PNI as a valuable predictor for survival outcomes in patients with stage Ⅲ colon cancer receiving curative tumor resection followed by adjuvant chemotherapy.

Shock index of patients with sepsis after continuous blood purification treatment and its relationship with systemic inflammatory response syndrome and immune response

Objective:To study the shock index of patients with sepsis after continuous blood purification (CBP) treatment and its relationship with systemic inflammatory response syndrome and immune response.Methods:A total of 88 patients with sepsis who underwent continuous blood purification treatment in our hospital between June 2012 and May 2016 were chosen as research subjects, shock index (SI) was compared before and after the treatment, and according to the level of SI after treatment, all patients were divided into shock group (n=27) with SI>0.5 points and no shock group (n=61) with SI≤0.5 points. Serum contents of inflammatory mediators, Th1/Th2 cellular immunity indexes, immunoglobulin and complement were compared between two groups of patients after treatment.Results: The level of SI in patients with sepsis was significantly lower than that before treatment. Serum contents of inflammatory mediators PCT, CRP and HMGB1 in no shock group were lower than those in shock group, contents of Th1 cytokines IL-2 and IFN-γ were higher than those in shock group, contents of Th2 cytokines IL-10 and IL-13 were lower than those in shock group, and contents of IgG, IgM, IgA, C3 and C4 were higher than those in shock group.Conclusion: The level of SI decreases in the patients with sepsis after CBP treatment, and SI level is directly correlated with the systemic inflammatory response syndrome and immune response levels.

Systemic Immune Inflammatory Index Is Associated with Pustular Psoriasis: A Single Center Retrospective Study

Introduction: Psoriasis is a chronic multi-systemic inflammatory skin disease that presents with erythema, thickness, and scaling of the skin. Genetic and environmental factors are associated with its etiology. Recently systemic immune inflammatory index, has been proposed as a biomarker for prognosis and severity prediction. Although it has been studied in psoriasis in general, no study exists for its association with the individual types of psoriasis. This study thus aimed to determine its association with clinical characteristics of psoriasis subtypes. Materials and Methods: Data were retrospectively retrieved from the hospital electronic medical database from January 2020 to August 2022. Only patients with CBC results were included. Clinical data retrieved were: Patients’ age, gender, type of psoriasis diagnosed, body mass index, duration of the disease, family history of psoriasis, history of smoking, diabetes, and hypertension records. Laboratory data retrieved were: Complete blood count (CBC), C-reactive protein, Immunoglobulin E (IgE), Total cholesterol, Triglycerides and Low-density lipoprotein cholesterol. Data were analyzed in SPSS and GraphPad prism. Results: The study enrolled 85 patients with psoriasis;56.47% males, and 43.53% females. 7.6% had psoriasis for less than 10 years, while 42.4% had the disease for more than 10 years. Psoriasis vulgaris was the most common diagnosis, 41.2%, followed by p. pustular, 30.6% and then p. erythroderma 28.2%. Mean age ± SD of the p. vulgaris, p. pustular and p. erythroderma patients were 47.3 ± 15.3;45.3 ± 14.6, and 57.1 ± 11.7 respectively. SII was significantly higher in p. pustular than the rest, (p Conclusion: In summary, systemic immune inflammatory index (SII) was significantly higher in psoriasis pustular than other subtypes of psoriasis, and had an association with hypertension in psoriasis pustular patients. These findings suggest a possible association between SII and psoriasis pustular that should be investigated in an independent study.

Systemic Inflammation Response Index and weight loss as prognostic factors in metastatic pancreatic cancer: A concept study from the PANTHEIA-SEOM trial

BACKGROUND The prognostic value of the Systemic Inflammation Response Index(SIRI)in advanced pancreatic cancer is recognized,but its correlation with patients´nutritional status and outcomes remains unexplored.AIM To study the prognostic significance of SIRI and weight loss in metastatic pancreatic cancer.METHODS The PANTHEIA-Spanish Society of Medical Oncology(SEOM)study is a multicentric(16 Spanish hospitals),observational,longitudinal,non-interventional initiative,promoted by the SEOM Real World-Evidence work group.This pilot study sought to analyze the association between weight loss and inflammatory status as defined by SIRI.The cohort stems from a proof-of-concept pilot study conducted at one of the coordinating centers.Patients with pathologically confirmed metastatic pancreatic adenocarcinoma,treated from January 2020 to January 2023,were included.The index was calculated using the product of neutrophil and monocyte counts,divided by lymphocyte counts,obtained within 15 days before initiation chemotherapy.This study evaluated associations between overall survival(OS),SIRI and weight loss.RESULTS A total of 50 patients were included.66%of these patients were male and the median age was 66 years.Metastasis sites:36%liver,12%peritoneal carcinomatosis,10%lung,and 42%multiple locations.Regarding the first line palliative chemotherapy treatments:50%received gemcitabine plus nab-paclitaxel;28%,modified fluorouracil,leucovorin,irinotecan and oxaliplatin,and 16%were administered gemcitabine.42%had a weight loss>5%in the three months(mo)preceding diagnosis.21 patients with a SIRI≥2.3×10^(3)/L exhibited a trend towards a lower median OS compared to those with a SIRI<2.3×10^(3)/L(4 vs 18 mo;P<0.000).Among 21 patients with>5%weight loss before diagnosis,the median OS was 6 mo,in contrast to 19 mo for those who did not experience such weight loss(P=0.003).Patients with a weight loss>5%showed higher SIRI levels.This difference was statistically significant(P<0.000).For patients with a SIRI<2.3×10^(3)/L,those who did not lose>5%of their weight had an OS of 20 mo,compared to 11 mo for those who did(P<0.001).No association was found between carbohydrate antigen 19-9 levels≥1000 U/mL and weight loss.CONCLUSION A higher SIRI was correlated with decreased survival rates in patients with metastatic pancreatic cancer and associated with weight loss.An elevated SIRI is suggested as a predictor of survival,emphasizing the need for prospective validation in the upcoming PANTHEIA-SEOM study.

Prognostic value of combined systemic inflammation response index and prognostic nutritional index in colorectal cancer patients

BACKGROUND The prognosis of colorectal cancer(CRC)patients is notably influenced by both inflammation and nutritional status.The prognostic nutritional index(PNI)and systemic inflammatory response index(SIRI)have been reported in prognostic studies of various tumors.However,the efficacy of the combination of the two in predicting the prognosis of CRC patients has not been studied.AIM To evaluate the effectiveness of PNI and SIRI in predicting the prognosis of patients with CRC.METHODS We retrospectively gathered data from 470 CRC patients who underwent feasible radical surgery at Xinjiang Cancer Hospital.The optimal cut-off values for SIRI and PNI,along with their predictive power for survival,were determined through area under the receiver operating characteristic curve using time-dependent receiver operating characteristic analysis.The Kaplan-Meier method and log-rank test were applied to assess prognostic impact,and a multifactorial Cox proportional hazards model was employed for analysis.Additionally,a new model,PSIRI,was developed and assessed for its survival prediction capability.RESULTS The optimal cutoff values for PNI and SIRI were determined to be 47.80 and 1.38,respectively.Based on these values,patients were categorized into high PNI and low PNI groups,as well as high SIRI and low SIRI groups.Significant differences in age,T stage,neutrophil to lymphocyte ratio(NLR),monocyte to lymphocyte ratio(MLR),and platelet-to-lymphocyte ratio(PLR)subgroups were observed between the PNI groups in the baseline profile.In the SIRI group,notable differences were found in gender,T stage,nerve invasion,intravascular tumor emboli,NLR,MLR,and PLR subgroups.Both low PNI and high SIRI were identified as independent risk factors for poor prognosis in CRC patients.When combined into the PSIRI model,it was shown that patients with a PSIRI≤1 had a higher risk of death compared to those with a PSIRI of 2.CONCLUSION We assessed the impact of PNI and SIRI on the prognostic survival of CRC patients and developed a new model,PSIRI.This model demonstrated superior predictive accuracy,with a concordance index of 0.767.
