Prognostic importance of the inflammation-based Glasgow prognostic score in patients with gastric cancer

CAR, mGPS and hs-mGPS: What is among them the best gero-biomarker for age-related diseases? And for what clinical application?

The identification of biomarkers linked to the onset, progression, and prevention of age-related diseases (ARD), in the era of personalized medicine, represents the best goal of geroscience. Geroscience has the fundamental role of exploring and identifying the biological mechanisms of aging to suggest interventions capable of stopping/delaying the many pathological conditions and disabilities related to age. Therefore, it has become its key priority, as well as that of clinical practice and research, based on identifying and validating a range of biomarkers, geromarkers, which can be used to diagnostic, prognostic, or predictive clinical purposes. Indeed, geromarkers have, the potential to predict ARD trajectories and facilitate targeted interventions to slow down the related disabilities. Here our attention is paid to the inflammatory indexes (CAR, mGPS, hs-mGPS) linked to the relationship between the plasma levels of two inflammatory analytes, the typical positive protein of the acute phase, and the negative one, i.e. c-reactive protein (CRP) and albumin, respectively. These indexes allow us to understand the magnitude of the two main mechanisms predicted to influence the aging process, including inflammation and immunosenescence, as well as the degree of ARD severity. Evidence on their relationship with ARD is widely reported and discussed, to understand which can represent the best ARD geromarker, and its clinical application.

Prognostic significance of the preoperative C-reactive protein-albumin-lymphocyte (CALLY) index on outcomes after gastrectomy for gastric cancer

PURPOSE

Systemic inflammatory response markers are reported to be prognostic for patients with cancer. The C-reactive protein (CRP)-albumin-lymphocyte (CALLY) index has been established as an immuno-nutritional scoring system. The aim of this study was to clarify the impact of the preoperative CALLY index on the outcome of patients undergoing gastrectomy for gastric cancer.

METHODS

We analyzed the data of 826 patients who underwent gastrectomy for stage I, II, or III gastric cancer between 2010 and 2017. The CALLY index was defined as (albumin × lymphocyte)/(CRP × 104).

RESULTS

The cut-off of the CALLY index was 2. The 147 patients with a preoperative CALLY index < 2 had significantly worse overall survival (OS) and relapse-free survival (RFS) than those with a CALLY index ≥ 2 (P < 0.01, P < 0.01, respectively). Multivariate analysis identified that a CALLY index < 2 (P = 0.02), intraoperative blood loss (P < 0.01), and stage II or III disease (P < 0.01) were independent and significant predictors of worse RFS. A CALLY index < 2 (P = 0.01), intraoperative blood loss (P < 0.01), postoperative complications (P = 0.02), and stage II or III disease (P < 0.01) were independent and significant predictors of worse OS.

CONCLUSION

The preoperative CALLY index was independently associated with a poor prognosis for patients after gastrectomy for gastric cancer.

Role of modified Glasgow Prognostic Score in patients with achalasia who underwent laparoscopic Heller-myotomy with Dor-fundoplication

BACKGROUND

Systemic inflammatory response is significant prognostic indicator in patients with various diseases. The relationship between prognostic scoring systems based on the modified Glasgow Prognostic Score (mGPS) and achalasia in patients treated with laparoscopic Heller‑myotomy with Dor‑fundoplication (LHD) remains uninvestigated. This study aimed to examine the role of mGPS in patients with achalasia.

METHODS

457 patients with achalasia who underwent LHD as the primary surgery between September 2005 and December 2020 were included. We divided patients into the mGPS 0 and mGPS 1 or 2 groups and compared the patients' background, pathophysiology, symptoms, surgical outcomes, and postoperative course.

RESULTS

mGPS was 0 in 379 patients and 1 or 2 in 78 patients. Preoperative vomiting and pneumonia were more common in patients with mGPS of 1 or 2. There were no differences in surgical outcomes. Postoperative upper gastrointestinal endoscopy revealed that severe esophagitis was more frequently observed in patients with mGPS of 1 or 2 (P < 0.01). The clinical success was 91% and 99% in the mGPS 0 and mGPS 1 or 2 groups, respectively (P < 0.01).

CONCLUSIONS

Although severe reflux esophagitis was more common in patients with achalasia with a high mGPS, good clinical success was obtained regardless of the preoperative mGPS.

Textbook Neoadjuvant Outcome-Novel Composite Measure of Oncological Outcomes among Gastric Cancer Patients Undergoing Multimodal Treatment

The incidence of gastric cancer (GC) is expected to increase to 1.77 million cases by 2040. To improve treatment outcomes, GC patients are increasingly treated with neoadjuvant chemotherapy (NAC) prior to curative-intent resection. Although NAC enhances locoregional control and comprehensive patient care, survival rates remain poor, and further investigations should establish outcomes assessment of current clinical pathways. Individually assessed parameters have served as benchmarks for treatment quality in the past decades. The Outcome4Medicine Consensus Conference underscores the inadequacy of isolated metrics, leading to increased recognition and adoption of composite measures. One of the most simple and comprehensive is the "All or None" method, which refers to an approach where a specific set of criteria must be fulfilled for an individual to achieve the overall measure. This narrative review aims to present the rationale for the implementation of a novel composite measure, Textbook Neoadjuvant Outcome (TNO). TNO integrates five objective and well-established components: Treatment Toxicity, Laboratory Tests, Imaging, Time to Surgery, and Nutrition. It represents a desired, multidisciplinary care and hospitalization of GC patients undergoing NAC to identify the treatment- and patient-related data required to establish high-quality oncological care further. A key strength of this narrative review is the clinical feasibility and research background supporting the implementation of the first and novel composite measure representing the "ideal" and holistic care among patients with locally advanced esophago-gastric junction (EGJ) and GC in the preoperative period after NAC. Further analysis will correlate clinical outcomes with the prognostic factors evaluated within the TNO framework.

Preoperative NUn score serves as a robust predictor of overall and disease-specific survivals following radical surgery for gastric cancer

PURPOSE

Methods to preoperatively stratify oncological risks associated with gastric cancer (GC) are limited. Host inflammatory parameters, i.e., serum C-reactive protein (CRP) and albumin levels, are known to be associated with outcomes. We examined the relationships between disease-specific mortality and four CRP-albumin-based indices (CRP-albumin ratio [CAR], modified Glasgow prognostic score [mGPS], Osaka prognostic score [OPS], and NUn score) preoperatively measured in cases with resectable GC.

METHODS

Survival outcomes of 1290 consecutive GC patients with oncological gastrectomy were reviewed. Predictive significances of preoperative CAR, mGPS, OPS, and NUn scores were assessed with time-dependent receiver operating characteristic curves and Cox regression analyses.

RESULTS

Median follow-up was 107 months. Area under the curve for predicting overall and disease-specific survivals (OS/DSS) for the preoperative NUn score was clearly superior to those of the other parameters. On univariate Cox regression analysis, preoperative CAR, mGPS, OPS, and the NUn score all correlated significantly with OS/DSS. On multivariate Cox regression analysis, the preoperative NUn score, as a continuous variable, showed an independent relationship with OS (hazard ratio [HR] 1.32, 95% confidence interval [CI] 1.16-1.50, per 1-unit increase, P < 0.001) and even DSS (HR 1.23, 95% CI 1.02-1.49, P = 0.032). The other three markers failed to maintain independence for DSS.

CONCLUSIONS

Preoperative NUn scores are stably associated with outcomes, including disease-specific mortality, possibly serving as a simple measure to define the likelihood of progression to systemic disease after meticulous surgery for GC, which may contribute to identifying patients who would benefit from additional modalities.

Inflammatory risk of albumin combined with C-reactive protein predicts long-term cardiovascular risk in patients with diabetes

AIMS

The purpose of this study was to evaluate the predictive value of inflammatory risk as defined by the Glasgow Prognostic Score (GPS) for cardiovascular death in patients with diabetes.

METHODS

This study included 4956 patients (≥18 years old) with diabetes in the National Health and Nutrition Survey from 1999 to 2010. The mortality rate was determined by the correlation with the national death index on December 31, 2019. The GPS was composed of the serum C-reactive protein and the albumin. The primary outcome was cardiovascular death and the secondary outcome was all-cause death. The Cox proportional risk model adjusted for demographic factors and traditional cardiovascular risk factors was used to analyze the cumulative risk of outcomes.

RESULTS

Among 4956 diabetes patients with a median follow-up of 10.9 years, 601 cardiovascular deaths and 2187 all-cause deaths were recorded. After adequate model adjustment, compared with the low GPS group, the high GPS group (HR, 1.257 (1.007-1.570), P = 0.043) had a higher cardiovascular mortality. Compared with the low GPS group, the all-cause mortality of the high GPS group (HR, 1.394 (1.245-1.560), P < 0.001) was higher. The results of subgroup analyses were similar with that of the overall cohort.

CONCLUSIONS

The inflammatory risk as defined by the GPS was closely related to the increased risk of cardiovascular and all-cause death in patients with diabetes. It may be a convenient and efficient clinical practical risk assessment tool for patients with diabetes.

Prognostic Value of Inflammatory Burden Index in Advanced Gastric Cancer Patients Undergoing Multimodal Treatment

Since increasing evidence underlines the prominent role of systemic inflammation in carcinogenesis, the inflammation burden index (IBI) has emerged as a promising biomarker to estimate survival outcomes among cancer patients. The IBI has only been validated in Eastern gastric cancer (GC) patients; therefore, the aim of this study was to evaluate the IBI as a prognostic biomarker in Central European GC patients undergoing multimodal treatment. Ninety-three patients with histologically confirmed GC who underwent multimodal treatment between 2013 and 2021 were included. Patient recruitment started with the standardization of neoadjuvant chemotherapy (NAC). Blood samples were obtained one day prior to surgical treatment. The textbook outcome (TO) served as the measure of surgical quality, and tumor responses to NAC were evaluated according to Becker's system tumor regression grade (TRG). A high IBI was associated with an increased risk of postoperative complications (OR 2.95, 95% CI 1.13-7.72). In multivariate analysis, a high IBI (HR = 2.56, 95% CI 1.28-5.13) and a high neutrophil-to-lymphocyte ratio (NLR, HR = 2.55, 95% CI 1.32-4.94) were associated with an increased risk of death, while NAC administration (HR = 0.40, 95% CI 0.18-0.90) and TO achievement (HR = 0.42, 95% CI 0.22-0.81) were associated with a lower risk of death. The IBI was associated with postoperative complications and mortality among GC patients undergoing multimodal treatment.

The prognostic value of the controlling nutritional status (CONUT) score in predicting outcomes of esophageal cancer patients receiving radiotherapy with or without chemotherapy

Background

Controlling nutritional status (CONUT) scores and systemic immune-inflammation index (SII) values are associated with the prognosis of several common malignancies. The current study aimed to explore the prognostic value of CONUT scores and SII values in patients with esophageal cancer (EC) receiving radical radiotherapy (RT) or concurrent chemoradiotherapy (CCRT).

Methods

We calculated the pre-RT CONUT scores and SII values of 62 patients with EC receiving RT or CCRT. Receiver operating characteristic (ROC) curves were used to determine the adequate cut-off values. The Kaplan-Meier method and Cox proportional hazard model were used to analyze the association between CONUT scores and SII values and prognosis.

Results

The 1-year progression-free survival (PFS) and 1-year overall survival (OS) rates of the 62 patients were 51.61% and 66.13%, respectively. Based on the time-dependent ROC curve for the 1-year OS of all patients, the optimal cut-off value was 622.02 for the SII and a score of 1 for the CONUT score. The univariate analysis showed that the CONUT score (P=0.036), tumor-nodal-metastasis (TNM) stage (P<0.01), and CCRT (P=0.008) significantly affected the survival of EC patients. The multifactorial analysis showed that the CONUT score (P=0.041) and TNM stage (P<0.01) were independent prognostic factors affecting clinical outcomes in patients with EC undergoing radical RT or CCRT.

Conclusions

The pre-RT CONUT score could be an effective predictor of prognosis in patients with EC receiving radical RT or CCRT; however, the pre-RT SII value had no clinical value in predicting survival in our study.

Systemic inflammatory biomarkers as prognostic tools in patients with gastroesophageal adenocarcinoma

PURPOSE

Gastroesophageal adenocarcinoma is associated with poor prognosis, even in resectable stages. Systemic inflammation plays a key role in cancer progression. Yet, information on prognostic values of systemic inflammatory parameters in European cohorts is scarce.

METHODS

We analysed systemic inflammatory biomarkers (neutrophil-to-lymphocyte ratio (NLR), leucocyte-to-lymphocyte ratio (LLR), platelet-to-lymphocyte ratio (PLR), systemic inflammation response index (SIRI) and modified Glasgow Prognostic Score (mGPS)) at the time of cancer diagnosis and their association with overall survival (OS) in patients with gastroesophageal adenocarcinoma treated at the Medical University of Vienna between 1990 and 2020.

RESULTS

In this analysis of 769 patients with gastroesophageal adenocarcinoma, higher mGPS (0-2) scores were associated with shorter OS in the overall cohort (24.9 versus 11.9 versus 7.6 months; HR 1.74, 95% CI 1.549-1.056; p < 0.001), in locally advanced (31.1 versus 19.8 versus 13.9 months, HR 1.561, 95% CI 1.274-1.912; p < 0.001) and in advanced/metastatic settings (12.3 versus 7.3 versus 5.8 months; HR 1.377, 95% CI 1.777-1.611; p < 0.001). In multivariate analyses, the association of mGPS with the OS stayed statistically significant in the locally advanced cohort (HR 1.397, 95% CI 1.068-1.828; p = 0.015), whereas NLR, LLR, PLR and SIRI did not. mGPS was associated with more advanced stages (p < 0.001) and weight loss (p = 0.002).

CONCLUSION

mGPS poses a feasible prognostic tool in patients with locally advanced gastroesophageal cancer.

A low cumulative perioperative prognostic nutritional index predicts poor long-term outcomes in patients with gastric cancer: A single-center retrospective study in Japan

PURPOSE

Perioperative surgical stress and systemic inflammation resulting from complex interactions between cancer and the host play an important role in cancer progression. This retrospective study compared the prognostic impact of various perioperative cumulative inflammation- and nutrition-based markers in patients with gastric cancer (GC).

METHODS

This study included 301 patients with a histopathological diagnosis of gastric adenocarcinoma who underwent curative surgery. Perioperative cumulative markers were calculated using the newly developed trapezoidal area method.

RESULTS

The cumulative prognostic nutritional index (cum-PNI) had the highest area under the receiver operating characteristic (ROC) curve for predicting the overall survival (OS) as well as the relapse-free survival (RFS). The cum-PNI was significantly correlated with tumor-related factors, including tumor size, depth of invasion, lymph node metastasis, lymphatic involvement, vascular involvement, and TNM stage classification. The cum-PNI was also significantly correlated with surgical factors, including surgical approach, gastrectomy, lymphadenectomy, intraoperative blood loss, and postoperative complications. Furthermore, the OS and RFS were poorer in patients with a low cum-PNI (< 236.3) than in those with a high cum-PNI (> 236.3). A multivariate analysis indicated that a low cum-PNI was an independent prognostic indicator in patients with GC.

CONCLUSIONS

The cum-PNI might be useful for predicting the prognosis and guiding the perioperative management of patients with GC.

Prognostic Value of Inflammation Biomarkers in Penile Squamous Cell Carcinoma Patients Without Distant Metastasis

BACKGROUND

To investigate the value of the presurgical inflammatory biomarkers including C-reactive protein (CRP), albumin (ALB), C-reactive protein to albumin ratio (CAR), Glasgow prognostic score (GPS), the modified GPS (mGPS), and the high-sensitivity modified GPS (Hs-mGPS) in penile squamous cell carcinoma (PSCC) without distant metastasis and develop a tool to predict the overall survival (OS) of PSCC patients.

METHODS

We retrospectively enrolled 271 PSCC patients without distant metastasis from 2006 to 2021. Patients were divided into 2 cohorts by a 7:3 ratio-a training cohort (n = 191) and a validation cohort (n = 80). We performed cox regression analyses on the training cohort and constructed a nomogram to predict OS over 1, 3, and 5 years. Data from the validation cohort was used to validate the nomogram's predictive power.

RESULTS

According to Kaplan-Meier analysis, elevated CRP (P < .001), hypoalbuminemia (P = .008), higher CAR (P < .001), higher GPS score (P < .001), higher mGPS score (P < .001), and higher Hs-mGPS score (P = .015) were associated with a decreased overall survival. GPS score, along with age, pathology N stage, and grade, was found to be an independent risk factor for poor prognosis in the multivariate analysis. We constructed a nomogram based on the prespecified variables predicting 1-, 3- and 5-year OS. The C-indexes of the nomogram in the training and validation cohorts were 0.871 and 0.869, respectively. The decision curve analysis showed that the nomogram had a larger net benefit. The Kaplan-Meier curves showed significant differences between the risk groups categorized according to the nomogram (P < .001).

CONCLUSIONS

Inflammation biomarkers of systemic inflammation and nutritional status play an important role in individual OS predictions for PSCC patients without distant monitoring. The establishment of the nomogram provided a tool to predict the survival of 1-, 3-, and 5-year OS in PSCC patients without distant metastasis.

Subacute prognosis of oral nutrition (SPOON): Development of a multivariable prognostic model for complete oral intake in tube-fed subjects with acquired brain injury

BACKGROUND & AIMS

Enteral feeding is very common following an acquired brain injury. However, no prognostic models for oral food intake have been developed for subacute rehabilitation. The aim of this study was to develop a prognostic model and online tool, coined "subacute prognosis of oral nutrition" (SPOON), for complete oral intake in tube-fed subjects with acquired brain injury.

METHODS

The model was developed using routinely gathered clinical data from a cohort of 1233 adult patients who were tube-fed at admission for sub-acute inpatient rehabilitation. Candidate predictors were included based on scientific evidence and their availability in the medical records within the first days following admission. The outcome was time until achieving complete oral food intake without any tube-feeding supplements. Time until complete oral intake was analyzed by discrete time-to-event analysis with logit-link and presented as daily odds ratios (OR) with 95% confidence intervals (CI).

RESULTS

The following predictors of complete oral intake were included in the model: age, diagnosis, cuffed tracheostomy tube, days from injury to admission for rehabilitation, and the Early Functional Abilities (EFA) sum score. Multiple adjusted analyses were performed stratified by cuffed tracheostomy tube status. Some of the strongest predictors of complete oral intake were age 18-40 years, OR 1.99 (95%CI: 1.53; 2.59); 0-2 weeks since injury, OR 3.75 (95%CI: 2.72; 5.16); and EFA 61-100 (slight/no disturbance in function), OR 5.81 (95%CI: 4.47; 7.55). The online prognostic tool SPOON was evaluated in a usability study. Based on feedback from clinicians, the tool was further refined to enable extraction of data for prediction directly from medical records.

CONCLUSIONS

The objective of SPOON is to complement the planning of rehabilitation initiatives and inform discussions to determine if a percutaneous endoscopic gastrostomy (PEG) tube should be inserted. SPOON is being implemented locally, but external validation based on appropriate data modeling is warranted before further clinical implementation.

Is Systemic Inflammatory Response Index (SIRI) a Reliable Tool for Prognosis of Gastric Cancer Patients Without Neoadjuvant Therapy?

BACKGROUND

The systemic inflammatory response index (SIRI), which depends on peripheral neutrophil, monocyte, and lymphocyte count, was found as an effective prognostic indicator for various malignancies. This study aims to investigate the predictive value of preoperative SIRI in the prognosis of gastric cancer patients without neoadjuvant therapy.

METHODS

 The patients who underwent gastric cancer surgery in Marmara University Hospital's General Surgery Department between 2019 and 2021 were analyzed retrospectively. SIRI was calculated from preoperative peripheral blood samples' neutrophil, lymphocyte, and monocyte count. The optimal cut-off value for SIRI was calculated by the receiver operating characteristics (ROC) curve and was found to be 1.35. The clinicopathological outcomes and overall survival (OS) were analyzed under two groups according to the SIRI values lower or higher than 1.35.

RESULTS

 The number of eligible patients was 199. The median follow-up time was 25 (1-56) months. The higher SIRI was associated with male gender (p = 0.044), lower serum albumin (0.002) level, and Clavien-Dindo (CD) Grade III and higher complications (p = 0.018). However, there was no significant difference between the groups regarded pathological tumor, nodes, and metastases (TNM) stages, histological grade, and Lauren Type. In addition, OS and stage-specific OS were similar between the groups.

CONCLUSIONS

 SIRI may be a valuable and effective predictive indicator for postoperative morbidity. The prognostic performance of SIRI on long-term OS is still controversial. Further investigations are needed into this topic.

The relationship of different preoperative inflammatory markers with the prognosis of gastric carcinoma

BACKGROUND

It is aimed to determine the prognostic values of preoperative inflammatory biomarkers in patients undergoing curative surgery for gastric carcinoma and to contribute to the development of prognostic modeling.

OBJECTIVE

To investigate the effect of various different preoperative inflammatory markers on the prognosis of gastric carcinoma.

MATERIAL AND METHOD

The medical data and the mortality status of 91 patients who underwent total or subtotal gastrectomy operation for gastric carcinoma at Mersin City Training and Research Hospital between 2016 and 2020 were retrospectively reviewed from the hospital records and patient files. The patients' demographic characteristics, tumor location, histopathological diagnosis, pathological stage, tumor markers, and preoperative inflammatory and hematological markers were analyzed. Based on these data, tumor stage, metastatic lymph node ratio (MLR), lactate dehydrogenase albumin ratio (LAR), neutrophil-lymphocyte ratio (NLR), and platelet lymphocyte ratio (PLR) were calculated. The relationship between these parameters and postoperative survival was analyzed. Statistical analyses were performed with IBM SPSS for Windows, version 17.0 (IBM Corporation, Armonk, New York, United States).

RESULTS

The correlation analysis of the parameters affecting survival showed that, in addition to an advanced tumor stage, inflammatory parameters like NLR, PLR, and LAR adversely affected survival.

CONCLUSION

Preoperative NLR, PLR, LAR, and advanced tumor stage may help determine the survival of gastric carcinoma patients. Multiple studies with larger series are needed on this subject.

Prognostic Effect of the Controlling Nutritional Status Score in Patients With Esophageal Cancer Treated With Immune Checkpoint Inhibitor

In recent years, a growing number of clinical studies have shown that immune checkpoint inhibitor (ICI) can increase the remission rate and improve the prognosis of patients with esophageal cancer. The Controlling Nutritional Status (CONUT) score is a novel nutritional indicator that can predict the prognosis of certain malignancies. We retrospectively analyzed the clinical data of 69 patients with advanced esophageal cancer treated with ICI and assessed the relationship between clinicopathological factors including CONUT score, systemic immune-inflammatory index (SII), and neutrophil-to-lymphocyte ratio and the prognosis. We found the CONUT score and SII, neutrophil-to-lymphocyte ratio were an independent prognostic factor for overall survival ( P <0.05). Furthermore, among patients treated with ICI, a high CONUT score was associated with a significantly worse progression-free survival (PFS) and overall survival compared with a low CONUT group. In conclusion, the CONUT can be used to predict the efficacy and prognosis of ICI therapy in patients with esophageal cancer. Our studies have shown that the CONUT score can be used as an effective indicator for the prognosis of patients with esophageal cancer receiving ICI.

Evaluation of an inflammation-based score for identification of appropriate patients for comprehensive genomic profiling

Performance status (PS) is widely used as an assessment of general condition in patients before performing comprehensive genomic profiling (CGP). However, PS scoring is dependent on each physician, and there is no objective and universal indicator to identify appropriate patients for CGP. Overall, 263 patients were scored using the modified Glasgow prognostic score (mGPS) from 0 to 2 based on the combination of serum albumin and c-reactive protein (CRP): 0, albumin ≥ 3.5 g/dl and CRP ≤ 0.5 mg/dl; 1, albumin < 3.5 g/dl or CRP > 0.5 mg/dl; and 2, albumin < 3.5 g/dl and CRP > 0.5 mg/dl. Overall survival was compared between mGPS 0-1 and mGPS 2 groups. The prognosis of patients with PS 0-1 and mGPS 2 was also evaluated. Thirty-nine patients (14.8%) were mGPS 2. Patients with mGPS 2 had significant shorter survival (14.7 months vs 4.6 months, p < 0.01). Twenty-eight patients were PS 0-1 and mGPS 2, and their survival was also short (5.6 months). Evaluation of mGPS is a simple and useful method for identifying patients with adequate prognosis using CGP.

The Modified Glasgow Prognostic Score Predicts Survival in Gastric Cancer Patients with Normal CEA and CA19-9

BACKGROUND

Traditionally, serum CEA and CA19-9 levels are good prognostic factors for gastric cancer. Many gastric cancer patients do not have elevated CEA or CA19-9 levels even at a very advanced stage. This study investigates the significance of the modified Glasgow prognostic score (mGPS) for the survival of gastric cancer patients with normal CEA and CA19-9.

METHODS

We retrospectively examined 488 curatively resected gastric cancer patients with normal preoperative serum levels of CEA and CA19-9 to evaluate the prognostic ability of mGPS for overall survival. The prognostic significance was analyzed by univariate and multivariate analyses.

RESULTS

Age, hemoglobin, white cell count, and neutrophils were each significantly correlated with the mGPS. Multivariate analyses showed that tumor location (HR, 0.803; 95% CI, 0.667-0.966; P=0.020), TNM stage (HR, 2.714; 95% CI, 2.250-3.275; P < 0.001), and mGPS (HR, 1.042; 95% CI, 1.105-1.772; P=0.023) were significantly associated with overall survival. Significant correlations were found between overall survival and mGPS. The Kaplan-Meier analysis demonstrated significant differences among patients with mGPS of 0, 1, and 2 (P < 0.001), with the mortality rate being higher for patients with a higher mGPS.

CONCLUSION

The mGPS can predict survival in gastric cancer patients with normal CEA and CA19-9.

Combined analysis of preoperative and postoperative lymphocyte-C-reactive protein ratio precisely predicts outcomes of patients with gastric cancer

Background

The systemic inflammatory response resulting from the complex interactions between cancer and the host plays an important role in cancer development. Recently, the lymphocyte-C-reactive protein ratio (LCR), which is a hematological and biochemical marker that reflects the systemic inflammatory response and nutritional status, has been reported to be associated with poor survival. Similar results were observed in patients with certain cancer types. However, these studies focused on the preoperative LCR, and thus far, no studies have reported the relationship between postoperative LCR and prognosis in patients with gastric cancer (GC).

Methods

This study enrolled 455 patients with a histopathological diagnosis of gastric adenocarcinoma who underwent curative surgery at our institution between 2005 and 2018. The relationship between both the preoperative and postoperative LCR and the prognosis of patients with GC was retrospectively investigated.

Results

Preoperative LCR showed significant correlations with tumor-related factors, such as tumor size, depth of invasion, and lymph node metastasis. By contrast, no correlation was observed between postoperative LCR and tumor-related factors. The 5 year survival rate was significantly worse in patients with low preoperative LCR than in those with high preoperative LCR (65.4% vs. 83.9%, p < 0.0001). Similarly, the 5 year survival rate was also significantly worse in patients with low postoperative LCR than in those with high postoperative LCR (67.0% vs. 84.1%, p < 0.0001). Furthermore, combination analysis of the pre- and postoperative LCR revealed that the prognosis of patients with both low pre- and postoperative LCR was worse in patients with GC (5 year survival rate was 52.0%). A multivariate analysis indicated that a low pre- and postoperative LCR and age and lymph node metastasis were independent prognostic indicators.

Conclusions

The combination of preoperative and postoperative LCR appears to be useful in predicting the prognosis of patients with GC.

Peking Prognostic Score, Based on Preoperative Sarcopenia Status, Is a Novel Prognostic Factor in Patients With Gastric Cancer

Background

This study focused on assessing the role of the Peking prognostic score (PPS), a novel prognostic index based on muscle atrophy and lymphocyte-to-C-reactive protein ratio, within gastric cancer patient prognosis.

Methods

We analyzed the data collected from 774 gastric cancer cases between April 2011 and February 2016 (discovery cohort). The results were assessed in 575 gastric cancer cases from March 2016 to September 2019 (validation cohort). For evaluating skeletal muscle mass, we obtained computed tomography images at the third lumbar vertebra level (L3). We performed a time-dependent receiver operating characteristic curve (t-ROC) to analyze PPS’s prognostic significance with others.

Results

The discovery cohort enrolled altogether 774 patients with non-metastatic gastric cancer, including 639 (82.5%) men along with 135 (17.5%) women. The patients were divided into 3 groups; 166 patients (21.4%) were assigned into group 0, 472 (60.9%) in group 1, and 136 (17.7%) in group 2, respectively. An increased PPS was in direct proportion to an elder age, reduced body mass index, higher Pathological Tumor Lymph Node Metastasis stage, perineural invasion, and vascular invasion. We identified PPS to independently estimate patient overall survival (OS) together with disease-free survival (DFS; both P &lt; 0.001). Additionally, as revealed by t-ROC analysis, PPS exhibited the highest sensitivity compared with other prognostic scoring systems in predicting patient survival. Finally, we evaluated the prognostic value of PPS in the validation cohort and confirmed that preoperative PPS independently estimates patient OS and DFS.

Conclusion

The PPS accounts for an efficient nutrition-inflammation prognostic scoring system in gastric cancer patients.

Comprehensive risk score of the E-PASS as a prognostic indicator for patients after elective and emergency curative colorectal cancer surgery: A multicenter retrospective study

OBJECTIVE

To evaluate the prognostic value of the comprehensive risk score (CRS) of the Estimation of Physiologic Ability and Surgical Stress for managing patients with colorectal cancer (CRC) who underwent elective and emergency colorectal cancer surgery with curative intent.

SUMMARY BACKGROUND DATA

CRS, which is calculated based on both clinical and surgical factors, is a good predictor of postoperative complications and mortality. However, the impact of CRS in CRC prognosis remains unclear.

METHODS

Patients with CRC who underwent curative resection between 2010 and 2019 were retrospectively enrolled in this study. The cohort was divided into the low and high CRS groups. The prognostic value of CRS was evaluated via Cox regression and Kaplan-Meier analyses. The CRS cutoff value was obtained using the Youden index applied to OS curves and have not been validated by any validation cohorts.

RESULTS

In total, 2407 patients, including 1359 and 1048 patients with low and high CRS, respectively, were enrolled in this study. Multivariate analysis revealed that a CRS was an independent prognostic factor of overall and recurrence-free survival regardless of disease stage. Furthermore, adjuvant chemotherapy was beneficial for the survival of patients with stage III CRC in both high and low CRS groups; however, the survival benefit was limited in elderly high CRS patients.

CONCLUSIONS

CRS was a strong prognostic factor for CRC regardless of disease stage and might be considered as a biomarker for selecting elderly patients who are eligible for adjuvant chemotherapy.

Significance of intra/post-operative prognostic scoring system in hepatectomy for colorectal liver metastases

AIM

The prognostic impact of postoperative systemic inflammatory response using an intra/post-operative prognostic scoring system in patients with colorectal liver metastases (CRLM) after hepatic resection had never been investigated previously.

METHODS

In total, 149 patients who underwent hepatic resection for CRLM were analyzed retrospectively. Intra/post-operative prognostic scoring was performed using the postoperative modified Glasgow Prognostic Score (mGPS) at the first visit, after discharge, or a month after surgery during hospitalization. We investigated the association between clinicopathologic variables and disease-free survival or overall survival by univariate and multivariate analyses.

RESULTS

The median evaluation period of postoperative mGPS was 30 (26-36) days after hepatectomy. Seventy-one patients (48%) were classified as postoperative day 30 mGPS 1 or 2. In multivariate analysis, an extrahepatic lesion (P = .02), multiple tumors (P = .05), and postoperative day 30 mGPS 1 or 2 (P < .01) were independent and significant predictors of disease-free survival. Moreover, extrahepatic lesion (P = .04), and postoperative day 30 mGPS 1 or 2 (P = .02) were independent and significant predictors for overall survival. Patients with postoperative day 30 mGPS 1 or 2 had significantly more advanced tumors, more invasive surgery, and more chances of infectious postoperative complications than those with postoperative day 30 mGPS 0.

CONCLUSION

Postoperative systemic inflammatory response, as evidenced by intra/post-operative prognostic scoring system using postoperative day 30 mGPS, was a strong predictor for outcomes in patients who underwent liver resection for CRLM.

Postoperative C-reactive protein concentrations to predict infective complications following gastrectomy for cancer

BACKGROUND AND OBJECTIVES

Gastrectomy for gastric cancer is associated with significant infective postoperative complications. C-reactive protein (CRP) is a useful biomarker in the early detection of infective complications following major abdominal surgery. This single-centre retrospective study aimed to determine the relationship between postoperative CRP levels and development of postoperative infective complications after gastrectomy.

METHODS

Daily postoperative CRP levels were analyzed to determine a CRP threshold associated with infective complications. ROC curve analysis was used to determine which postoperative day (POD) gave the optimal cutoff. Multivariate analysis was performed to determine significant factors associated with complications.

RESULTS

One hundred and forty-four patients were included. A total of 61 patients (42%) had at least one infective complication. A CRP level of 220 mg/L was associated with the highest AUC (0.765) with a sensitivity of 70% and specificity of 76% (positive predictive value, 67%; negative predictive value, 78%). More patients with a CRP > 220 mg/L on POD 3 developed infective complications (67% vs. 21%, p < 0.001).

CONCLUSIONS

A CRP of more than 220 mg/L on POD 3 may be useful to alert clinicians to the increased risk of a postoperative infective complication or enable earlier safe discharge from critical care for those with a lower value.

Role of Systemic Inflammatory Reaction in Female Genital Organ Malignancies - State of the Art

Systemic inflammatory reaction (SIR) is an unfavorable prognostic factor in many malignancies and has a role in all stages of the neoplastic process: initiation, promotion, and disease progression. Analysis of SIR can be performed by assessing indicators (eg, lymphocyte-to-neutrophil, platelet-to-lymphocyte, and monocyte-to-neutrophil ratios) and products of neutrophils and lymphocytes (ie, the systemic immune-inflammation index), or by examining the relationship between levels of C-reactive protein and albumin (based on the Glasgow Prognostic Score, modified Glasgow Prognostic Score, and C-reactive protein-to-albumin ratio). Risk stratification is essential in the clinical management of cancer; hence, the evaluation of these factors has potential applications in the clinical management of patients with cancer and in the development of new therapeutic targets. This review summarizes the current knowledge on SIR indicators and presents their clinical utility in malignancies of the female genital organs.

Absent in melanoma 2 suppresses gastric cancer cell proliferation and migration via inactivation of AKT signaling pathway

Gastric cancer (GC) is the third leading cause of cancer-related mortality worldwide, and poses a great threat to public health. Absent in melanoma 2 (AIM2), a member of the pyrin-HIN family proteins, plays various roles across different types of cancers. However, the possible role of AIM2 in GC, as well as the underling mechanisms, are equivocal and need to be further explored. Herein, we identified that AIM2 expression was significantly down-regulated in GC tissues. Furthermore, loss of AIM2 was significantly associated with tumor size, lymph node metastasis (LNM) and tumor, node, metastases (TNM) staging, as well as poor prognosis in GC patients. Knockdown of AIM2 in GC cells significantly promoted cellular proliferation and migration, whereas AIM2 overexpression did the opposite. Mechanistically, we discovered that AIM2 regulates the AKT signaling pathway. In fact, the enhanced proliferation and migration ability induced by AIM2 knockdown was partially impaired in cells treated with the AKT inhibitor. Overall, our findings suggests that AIM2 is an independent prognostic marker and highlights a new entry point for targeting the AIM2/AKT signaling axis for GC treatment.

Pretreatment Glasgow prognostic score as a predictor of outcomes in nivolumab-treated patients with advanced gastric cancer

In Japan, South Korea, and Taiwan, nivolumab might provide overall survival benefits for patients with advanced gastric cancer. However, it is effective only in a limited number of patients. The Glasgow prognostic score is an indicator of the systematic inflammatory response and nutritional status. This study aimed to investigate the ability of the Glasgow prognostic score and other markers to predict the outcomes of patients treated with nivolumab. We reviewed the medical records of patients treated for advanced gastric cancer and who received nivolumab between February 2015 and June 2019 at Hyogo Cancer Center. The patients were categorized into two groups according to their Glasgow prognostic scores. Overall, 53.3% and 46.7% of the patients were assigned to groups with Glasgow prognostic scores of 0 and 1/2, respectively. The median durations of progression-free and overall survival of the participants were 2.3 and 5.7 months, respectively. The patients with a Glasgow prognostic score of 0 had significantly higher median overall survival than those with scores of 1 or 2 (16.4 vs. 4.2 months; p = 0.0006). This observation suggests that a pretreatment Glasgow prognostic score of 0 is associated with better outcomes, and this scoring system may be used as a predictor of outcomes in patients with advanced gastric cancer treated with nivolumab.

Preoperative Utility of the Glasgow Prognostic Score on Outcomes of Patients with Locally Advanced Gastric Cancer

PURPOSE

To assess the utility of the Glasgow Prognostic Score (GPS) obtained before curative resection for predicting outcomes in patients with advanced gastric cancer (GC).

METHODS

This study retrospectively analyzed the outcomes of 337 consecutive patients with GC who underwent curative surgery for locally advanced gastric cancer between January 2003 and June 2014. GPS was assessed within 4 days prior to surgery.

RESULTS

The number of patients with GPS scores of 0, 1, and 2 was 302, 26, and 9, respectively. There was significantly more blood loss during surgery and more postoperative complications in the GPS 1/2 group than in the GPS 0 group. Patients in the GPS 1/2 group had significantly poorer overall survival than those in the GPS 0 group (p = 0.001). On multivariate analysis, GPS 1/2 was identified as an independent factor for poor survival (p = 0.019).

CONCLUSION

GPS before curative resection might be a useful predictive factor for perioperative complications and survival in locally advanced GC.

Association of Preoperative Serum Carcinoembryonic Antigen and Gastric Cancer Recurrence: A Large Cohort Study

Background and Aim: Measuring postoperative carcinoembryonic antigen (CEA) is recommended by guidelines to help detecting recurrence of gastric cancer patients. However, the prognostic significance of elevated preoperative CEA is unclear. This study aims to investigate whether patients with elevated preoperative CEA have a higher risk of recurrence than patients with normal preoperative CEA.

Methods: We conducted a retrospective cohort study at a gastric cancer center in South China. Consecutive patients with stage I to III gastric adenocarcinoma who underwent curative resection at the center from January 2001 to February 2016 were identified. Patients were grouped into two cohorts: normal preoperative CEA (≤ 5 ng/ml), and elevated preoperative CEA (> 5 ng/ml). 3-year recurrence-free survival (RFS) and hazard function curves over time were estimated.

Results: A total of 1,596 patients (1,063 {66.6%} male; median {Interquartile range, IQR} age, 59 {50-66} years) were identified. Patients with elevated preoperative CEA had 15.5% lower 3-year RFS (n=222 {70.4%}) than the cohorts with normal preoperative CEA (n=1,374 {85.9%}). The hazard function of recurrence for the two cohorts peaked at the similar time (around 10 months after surgery). Multivariate Cox analyses confirmed that elevated preoperative CEA was independently associated with shorter RFS (Hazard Ratio {HR}, 1.69; 95% confidence interval {CI}, 1.26-2.27; P = 0.001).

Conclusions: Patients with elevated preoperative CEA are at increased risk for recurrence, especially within the first 24 months after surgery.

Glasgow prognostic score is a better predictor of the long-term survival in patients with gastric cancer, compared to the modified Glasgow prognostic score or high-sensitivity modified Glasgow prognostic score

Background: Inflammation influences cancer progression by increasing catabolism and impairing nutrient absorption. We compared the prognostic ability of three inflammation-based prognostic scoring systems—the Glasgow prognostic score (GPS), modified GPS (mGPS), and high-sensitivity mGPS (HS-mGPS)—in gastric cancer patients.

Materials and Methods: We retrospectively examined 434 curatively resected gastric cancer patients to evaluate the prognostic ability of scoring systems for overall survival (OS) and cancer-specific survival (CSS).

Results: OS analysis identified the following independent prognostic factors: GPS model: pathological stage (pStage, p < 0.001), carcinoembryonic antigen (CEA, p = 0.004), and GPS 1 (hazard ratio [HR], 1.929; 95% confidence interval [CI], 1.152-3.228; p = 0.013); mGPS model: body mass index (BMI, p = 0.027), pStage (p < 0.001), and CEA (p < 0.001); HS-mGPS model: BMI (p = 0.029), pStage (p < 0.001), and CEA (p = 0.003). mGPS and HS-mGPS were not independent prognostic factors for OS. CSS analysis of the GPS model identified pStage (p < 0.001), CEA (p = 0.015), and GPS 1 (HR; 2.095, 95% CI; 1.025–4.283; p = 0.043) and 2 (HR, 2.812; 95% CI, 1.111–7.116; p = 0.029) as independent prognostic factors; however, mGPS and HS-mGPS were not independent prognostic factors for CSS. Log-rank tests demonstrated significant differences in OS among patients with GPS 0 vs. 1 (p < 0.001) and 0 vs. 2 (p < 0.001) and in CSS among the three GPS (0 vs. 1; p = 0.005, 0 vs. 2; p < 0.001, 1 vs. 2; p = 0.009).

Conclusions: GPS most reliably predicts long-term survival of gastric cancer patients.

Predictors of survival among Japanese patients receiving first-line chemoimmunotherapy for advanced non-small cell lung cancer

Background

First‐line chemoimmunotherapy (CIT) has improved overall survival (OS) and progression‐free survival (PFS) outcomes among patients with non‐small cell lung cancer (NSCLC). The immunological and nutritional statuses of patients fluctuate during treatment using immune checkpoint inhibitors, and are closely related to treatment outcomes. However, it is unclear whether these markers are significant in patients who are receiving CIT.

Methods

This retrospective single‐center study evaluated 34 consecutive Japanese patients with NSCLC who were treated using first‐line CIT. Previously reported markers that reflect immunological and nutritional statuses were evaluated at three time points: at the start of CIT, after three weeks, and at the end of induction therapy.

Results

The median PFS was 7.2 months (95% confidence interval: 6.3 months–not reached) and the median OS was not reached (95% confidence interval: 9.6 months–not reached). The PFS duration was significantly associated with the baseline neutrophil‐to‐lymphocyte ratio and the three‐week values for the modified Glasgow prognostic score, C‐reactive protein‐albumin ratio, prognostic nutrition index, and advanced lung cancer inflammation index. The OS duration was significantly associated with the pre‐treatment values for the neutrophil‐to‐lymphocyte ratio and advanced lung cancer inflammation index, as well as the prognostic nutrition index at the end of induction therapy.

Conclusions

Immunological and nutritional markers could be useful for predicting the outcomes of CIT for Japanese patients with advanced non‐small cell lung cancer. The timing of their evaluation may also be important.

Key points

Significant findings of the study

Overall survival in patients receiving first‐line chemoimmunotherapy for advanced lung cancer were associated with pretreatment values of neutrophil‐to‐lymphocyte ratio, advanced lung cancer inflammation index, and the prognostic nutrition index at the end of induction therapy.

What this study adds

Repetitive evaluation of immunological and nutritional markers may be useful for guiding prognostication and treatment selection for Japanese patients with advanced lung cancer.

Clinical significance of peripheral blood-derived inflammation markers in advanced gastric cancer after radical resection

Background

The prognostic significance of peripheral blood-derived inflammation markers in patients with gastric cancer (GC) has not been elucidated. This study aimed to investigate the relationship between systemic inflammatory markers and GC prognosis.

Methods

A prospective observational cohort study involving 598 patients was conducted to analyze the prognosis of GC based on systemic inflammatory markers. The following peripheral blood-derived inflammation markers were evaluated: the neutrophil-lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), systemic immune-inflammation index (SII), C-reactive protein/albumin (CRP/Alb) ratio, Glasgow Prognostic Score (GPS), modified Glasgow Prognostic Score (mGPS), prognostic nutrition index (PNI), and prognostic index (PI). The receiver operating characteristics (ROC) curve and the Youden index were used to determine the optimal cutoff values. Univariate and multivariate analysis of prognostic factors was conducted accordingly.

Results

The optimal cutoff values of the PNI, fibrinogen, NLR, PLR, SII, and CRP/Alb were 49.5, 397 ng/dl, 2.5, 154, 556, and 0.05, respectively. Multivariate analysis showed that age, PLR, TNM stage, and chemotherapy were the independent prognostic factors for advanced gastric cancer (AGC). Adjuvant chemotherapy improved the long-term prognosis of patients with PLR ≥154, but chemotherapy had no significant effect on the survival of patients with PLR < 154.

Conclusions

Our findings show that higher PLR (≥154) is an independent risk factor for poor prognosis in GC patients. Besides, PLR can predict adjuvant chemotherapy (oxaliplatin/5-fluorouracil combination) response in patients with GC after surgery.

Prognostic value of postoperative C-reactive protein elevation versus complication occurrence: a multicenter validation study

BACKGROUND

Several studies have shown that postoperative complications worsen the prognosis of patients with malignancies. However, our previous study showed that C-reactive protein (CRP) elevation over 12 mg/dL was a more reliable prognostic indicator than complication occurrence. This large-scale, multicenter validation study aimed to confirm the prognostic value of postoperative CRP elevation in resectable gastric cancer.

METHODS

Data of 1456 patients with pT2-T4 gastric cancer who underwent R0 resection were collected from 21 institutions. The prognostic value of the highest postoperative serum level of CRP (CRP_max) during hospitalization was evaluated using the Kaplan-Meier method. The prognostic independence of CRP_max with assessed with a Cox multivariate analysis of recurrence-free survival (RFS).

RESULTS

RFS in the high CRP_max (≥ 12 mg/dL) group was significantly worse than that in the low CRP_max (< 12 mg/dL) group (log-rank P = 0.002). The recurrence pattern showed that liver metastasis occurred more frequently in the high CRP_max group (9.2%) than in the low CRP_max group (4.7%) (P = 0.001). In patients without intra-abdominal infectious complications, the high CRP_max group showed significantly worse RFS than the low CRP_max group (log-rank P = 0.026). In patients with intra-abdominal infectious complications, the high CRP_max group had worse RFS than the low CRP_max group, but this difference was not significant (log-rank P = 0.075). Cox multivariate analysis with 13 covariables showed that CRP_max (P = 0.043) was an independent prognostic factor, but postoperative complications were not (P = 0.387).

CONCLUSION

Postoperative CRP elevation was a better predictor of prognosis in patients with gastric cancer than the occurrence of intra-abdominal infectious complications.

Inflammatory markers for predicting overall survival in gastric cancer patients: A systematic review and meta-analysis

Systemic inflammatory biomarkers have begun to be used in clinical practice to predict prognosis and survival of cancer patients, but the approach remains controversial. We conducted a meta-analysis to determine the predictive value of the c-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), and Glasgow prognostic score (GPS)/modified Glasgow prognostic score (mGPS) in the clinical outcome of gastric cancer (GC) patients. We searched literature databases to identify relevant studies. All articles identified in the search were independently reviewed based on predetermined selection criteria. Meta-analysis was conducted to calculate the hazard ratio (HR) and 95% confidence intervals (CI) of overall survival of the included studies. A total of 41 eligible cohort studies, involving a total of 18,348 patients meeting the inclusion criteria, were considered for meta-analysis. Increases in CRP (HR = 1.654, 95% CI: 1.272–2.151), NLR (HR = 1.605, 95% CI: 1.449–1.779), and GPS/mGPS (HR = 1.648, 95% CI: 1.351–2.011) were significantly associated with poorer survival in patients with GC. Substantial heterogeneities were noted in all three markers (I² = 86.479%, 50.799%, 69.774%, in CRP, NLR, and GPS/mGPS, respectively). Subgroup analysis revealed a significant positive correlation between each marker and poor survival, regardless of country, study quality, cancer stage, study design, or the inclusion of patients undergoing chemotherapy. This meta-analysis demonstrates that CRP, NLR, and GPS/mGPS are associated with poor survival in patients with GC. Further prospective studies using standardized measurements are warranted to conclude the prognostic value of various inflammatory markers.

Modified Glasgow prognostic score can predict survival of muscle invasive bladder cancer patients after radiotherapy

In patients with various cancers, modified Glasgow prognostic score (mGPS) before treatment has predicted prognoses after antitumor therapy. This study aimed to assess whether pretreatment mGPS also has predictive value in patients with muscle-invasive bladder cancer (MIBC) after radiotherapy. A retrospective review accumulated 98 consecutive MIBC patients treated with definitive 3D-conformal radiotherapy from January 2011 to December 2016 in a single center. It included cT2-4bN0-3M0 patients with a median age of 79 years (range: 49 to 95 years). Radiotherapy was delivered at 60-66 Gy for bladder cancer. Patients were categorized in terms of their pretreatment serum albumin and C-reactive protein (CRP) values as mGPS_0, mGPS_1, and mGPS_2. Among them, cumulative overall survival (OS) rates were compared by Kaplan-Meier plots with log-rank tests. The number of patients with mGPS_0, mGPS_1, and mGPS_2 were 40, 40, and 18, respectively. The median follow-up time for all patients was 19 months (range: 2-73 months). The 2-year OS rate for all patients was 75.7%. The 2-year OS rates for mGPS_0, mGPS_1, and mGPS_2 were 85.1%, 71.3%, and 60.9%, respectively. Kaplan-Meier curves revealed a significantly higher cumulative OS rate for mGPS_0 compared with mGPS_1 and mGPS_2 (P = 0.003). Using multivariate Cox regression analysis, mGPS_0 and good performance status were associated with favorable OS rates, of which mGPS_0 was more significant (Hazard ratio 2.74, 95% CI 1.30-5.57, P = 0.008). Modified Glasgow prognostic score may be a novel biomarker that can predict survival in patients with MIBC after radiotherapy.

CCL19 suppresses gastric cancer cell proliferation, migration, and invasion through the CCL19/CCR7/AIM2 pathway

Absent in melanoma 2 (AIM2) has been reported to be an important inflammasome component that exerts tumor suppression in several tumors. However, whether CCL19/CCR7/AIM2 is involved in the progression of GC still remains unclear. Quantitative real-time and ELISA assay were used to determine the expressions of AIM2, CCL19 and CCR7 in GC tissues and cell lines. CCK-8, Edu staining, flow cytometry, Transwell assay, and tumorigenesis in nude mice were used to explore the function of AIM2 and CCL19 in vitro and in vivo. Apoptosis and inflammation-related biomarkers were detected by Western blot and ELISA assay. H&E staining was used to assess the histological changes in the subcutaneous tumor model. Immunohistochemistry (IHC) was used to evaluate the expression of Ki-67. We found that expression levels of AIM2, CCL19 and CCR7 were obviously lower in early GC tissues than those in progressive GC tissues. In vitro assays revealed that CCL19 treatment could enhance the suppressive effects of AIM2 overexpression on cell proliferation, migration, and invasion through CCR7. An in vivo assay also demonstrated that silencing of AIM2 reversed the suppressive effects of CCL19 on tumor growth. Collectively, CCL19 overexpression significantly inhibited GC cell proliferation and tumor growth in vitro and in vivo by up-regulating the CCR7/AIM2 pathway. Thus, CCL19 activated CCR7/AIM2 signaling pathway and it may be a potential therapeutic approach for GC therapy.

The prognostic value of preoperative fibrinogen-to-prealbumin ratio and a novel FFC score in patients with resectable gastric cancer

Background

Chronic inflammation is considered as a hallmark of gastric cancer (GC) and plays a critical role in GC progression and metastasis. This study aimed to explore the prognostic values of preoperative fibrinogen-to-prealbumin ratio (FPR), fibrinogen-to-albumin ratio (FAR), and novel FPR-FAR-CEA (FFC) score in patients with GC undergoing gastrectomy.

Methods

A total of 273 patients with resectable GC were included in this retrospective study. We performed Kaplan-Meier and Cox regression analyses to assess the prognostic role of preoperative FPR, FAR, and FFC score in patients with GC and analyze their relationships with clinicopathological features.

Results

Receiver operating characteristic curve (ROC) analysis revealed that the optimal cutoff values for FPR and FAR were 0.0145 and 0.0784, respectively. The FFC score had a higher area under the ROC curve than FAR and CEA. Elevated FPR (≥ 0.0145) and FAR (≥ 0.0784) were significantly associated with old age, large tumor size, tumor invasion depth, lymph nodes metastasis, advanced TNM stage, large Borrmann type, and anemia status. Kaplan-Meier analysis showed that high FPR, FAR, and FFC score were related to poor survival. Multivariate analyses indicated that FPR, FFC score, TNM stage, and tumor size were significant independent factors for survival.

Conclusions

Preoperative FPR and FFC score could be used as prospective noninvasive prognostic biomarkers for resectable GC.

The prevalence of cancer associated systemic inflammation: Implications of prognostic studies using the Glasgow Prognostic Score

The prognostic importance of SIR in patients with cancer is widely recognised. More recently it has become clear that the systemic inflammatory response is an important etiologic factor in the development of cancer cachexia. Two recent meta-analysis carried out in 2017 and 2018 were interrogated and the number of patients with specific cancer types were identified. The percentage of patients with operable cancer (n>28,000) who were systemically inflamed varied from 21% to 38%. The percentage of patients with inoperable cancer (n>12,000) who were systemically inflamed varied from 29% to 79%. Overall, the percentage of patients (n>40,000) who were systemically inflamed varied from 28% to 63% according to tumour type. The most commonly studied cancer was colorectal cancer (n∼10,000 patients) and 40% were systemically inflamed.

Evaluation of Systemic Inflammatory Response and Nutritional Biomarkers as Predictive Factors in Patients with Recurrent Gastric Cancer

BACKGROUND

The present study sought to evaluate host-related factors as predictors in patients receiving chemotherapy for recurrent advanced gastric cancer.

METHODS

Sixty-three patients were enrolled in the study and received chemotherapy for recurrent gastric cancer at the Kochi Medical School from 2008 to 2015. Clinicopathological information and systemic inflammatory response data were obtained retrospectively to investigate associations between baseline cancer-related prognostic variables and survival outcomes.

RESULTS

The median survival time was significantly higher for patients with a Glasgow prognostic score (GPS) of 0 compared to a GPS of 1 or 2 (18.2 vs. 7.1 months; p = 0.006), and for patients in the normal range for carbohydrate antigen-125 (CA125) compared to higher levels (17.9 vs. 4.1 months; p = 0.003). There was no significant influence on overall survival by age, gender, disease status, metastatic site, time to recurrence, carcinoembryonic antigen level, CA19-9 level, prognostic nutrition index, or neutrophil to lymphocyte ratio according to the results of the univariate log-rank tests. Multivariate survival analysis identified a GPS of 1 or 2 (hazard ratio, 3.520; 95% confidence interval, 1.343-9.227; p = 0.010) and a high CA125 level (hazard ratio, 3.135; 95% confidence interval, 1.276-7.697; p = 0.013) as significant independent predictors associated with a poorer prognosis in the studied group of cancer patients.

CONCLUSIONS

A GPS of 1 or 2 and a high level of CA125 are independent predictors of a poorer prognosis in patients receiving chemotherapy for recurrent gastric cancer.

Complete blood count-based inflammatory score (CBCS) is a novel prognostic marker for gastric cancer patients after curative resection

Background

We sought to investigate the prognostic value of complete blood count (CBC)-based biomarkers for patients with resectable gastric cancer (GC).

Methods

Patients with GC who underwent primary surgical resection between December 2008 and December 2013 were included. The estimated area under the curve (AUC) and multivariate Cox regression models were used to identify the best CBC-based biomarker. Time-dependent receiver operating characteristic (t-ROC) curve analysis was used to predict overall survival and compare the prognostic impact.

Results

In the 1810 patients analyzed, the median follow-up period was 51.0 months (range 1–101 months). Based on multivariate analysis, the lymphocyte-monocyte ratio (LMR) and hemoglobin (Hb) level were independent prognostic factors (both P < 0.05). Based on the LMR and Hb level, we established the CBC-based inflammatory score (CBCS). A higher CBCS was associated with older age, female sex, higher American Society of Anesthesiologists (ASA) score, proximal tumor location, larger tumor size, later stage and vascular involvement (all P < 0.05). Univariate analyses showed that a higher CBCS was also associated with worse overall survival (OS), which was consistent in each stage (all P < 0.05). Multivariate analysis revealed that the CBCS was a significant independent biomarker (P < 0.05). The AUC for the CBCS (0.627) was significantly higher than the AUCs for the LMR (0.573) and Hb level (0.605) (both P < 0.05). Furthermore, the t-ROC curve of the CBCS was superior to that of the prognostic nutritional index (PNI), systemic immune-inflammation index (SII), modified Glasgow prognostic score (mGPS) and C-reactive protein/albumin ratio (CRP/Alb) throughout the observation period.

Conclusion

The preoperative LMR and Hb level were optimal CBC-based biomarkers for predicting OS in GC patients after curative resection. Based on the LMR and Hb, we developed a novel and easily obtainable prognostic score called the CBCS, which may improve the prediction of clinical outcomes.

Overweight or Obesity is an Unfavorable Long-Term Prognostic Factor for Patients who Underwent Gastrectomy for Stage II/III Gastric Cancer

BACKGROUND

Obesity has been reported to be a prognostic factor for many diseases in epidemiological studies; however, the results of studies examining the relationship between obesity and gastric cancer (GC) prognosis are inconsistent.

METHODS

A total of 460 patients with Stage II and III GC who underwent open R0 gastrectomy were included. Age, sex, body mass index (BMI classified into < 18.5, 18.5-25, and ≥ 25 kg/m²), stage, and postoperative adjuvant chemotherapy were analyzed to investigate the correlation with relapse-free survival (RFS).

RESULTS

Five-year RFS was 51% for the study patients. Five-year RFS values were 47.6%, 54.3%, and 40.1% for patients with BMI < 18.5, 18.5-25, and ≥ 25 kg/m², respectively. The forest plot for relapse risk according to BMI showed a U shape. Multivariate analysis for RFS showed significant differences in stage and BMI; the hazard ratio for recurrence in patients with BMI ≥ 25 kg/m² was 1.42 (95% confidence interval: 1.01-2.02, p = 0.0423) with reference to patients with BMI < 25 kg/m². BMI ≥ 25.0 was associated with longer operation times, more blood loss, fewer lymph nodes dissected, more frequent postoperative surgical site infection, and intra-abdominal abscesses.

CONCLUSIONS

BMI ≥ 25 kg/m² is an unfavorable prognostic factor for patients who underwent gastrectomy for Stage II and III GC.

Significance of the Glasgow Prognostic Score in Predicting the Postoperative Outcome of Patients with Stage III Gastric Cancer

This study aimed at investigating the ability of a preoperative Glasgow prognostic score (GPS) to predict postoperative complications and survival outcomes in patients with stage III gastric cancer undergoing D2 gastrectomy. We retrospectively reviewed data from 272 such patients, treated between 2010 and 2016, at a Taiwanese medical center. The patients were categorized according to their GPS. In total, 36.8%, 48.5%, and 14.7% of the patients were assigned to groups with a GPS of 0, 1, and 2, respectively. Overall surgical complication rates in these groups were 30%, 45.5%, and 52.5% (p = 0.016); postoperative intensive care unit admission rates were 10%, 14.4%, and 22.5% (p = 0.15); postoperative 30-day re-admission rates were 6%, 15.2%, and 20% (p = 0.034); and the in-hospital mortality rates were 1.0%, 1.5%, and 10.0%, respectively (p = 0.006). The median survival times of the patients were 42.9 months (95% confidence interval [CI], 29.1-56.6), 22.6 months (95% CI, 19.3-25.8), and 16.6 months (95% CI, 7.8-25.4), respectively (p< 0.001). A significant correlation was observed between the preoperative GPS, short-term postoperative complications, and long-term survival outcomes in patients with gastric cancer undergoing D2 gastrectomy. These findings recommend the usage of the GPS as a predictive and prognostic factor in patients with gastric cancer considering surgical resection.

Postoperative Serum C-Reactive Protein Level Predicts Long-term Outcomes in Stage I Gastric Cancer

BACKGROUND

The aim of this study was to investigate the prognostic impact of postoperative systemic inflammation in patients with stage I gastric cancer.

METHODS

This study reviewed the medical records of 470 patients with stage I gastric cancer who underwent gastrectomy. The postoperative serum C-reactive protein (CRP) level on postoperative days (PODs) 1 and 3 and its peak value were evaluated as prognostic factors. A receiver operating characteristics curve analysis was performed to determine their cut-off values.

RESULTS

The CRP level on POD 3 (P = 0.001) and the peak CRP level (P = 0.007) were significantly associated with the overall survival rate. In the multivariate analysis, the CRP level on POD 3 (P = 0.002) and the peak CRP level (P = 0.008) were identified as independent predictors of the overall survival. The high CRP on POD3 group had significantly higher mortality rate from relapse of gastric cancer (P = 0.001) and infectious disease (P = 0.003) than the low CRP on POD 3 group. The CRP level on POD 3 was significantly associated with the patient sex, surgical procedure, duration of the operation, amount of blood loss, postoperative infectious complication, and peak CRP level.

CONCLUSIONS

The serum CRP level during the early postoperative period predicts the long-term outcomes in stage I gastric cancer. The present study suggests a significant influence of postoperative systemic inflammation on the survival of patients with stage I gastric cancer.

Lymphocyte-to-C-reactive protein ratio and score are clinically feasible nutrition-inflammation markers of outcome in patients with gastric cancer

BACKGROUNDS

Systemic inflammation arising from complex host-tumour interactions is considered the seventh hallmark of cancer. The aim of this study was to assess the clinical feasibility of our newly developed 'lymphocyte-to-C-reactive protein (CRP) ratio' (LCR) and 'lymphocyte CRP score' (LCS) for predicting short- and long-term outcomes in patients with gastric cancer (GC).

METHODS

In this observational study, we retrospectively analysed pre-operative LCRs and LCSs from 551 GC patients to elucidate these prognostic value for overall survival (OS) and disease free survival (DFS) and to clarify these predictive value for peri-operative risk of surgical site infection (SSI) in GC patients.

RESULTS

Reduced pre-operative LCRs significantly correlated with all of the well-established clinicopathological factors for disease development, including advanced T stage, venous and lymphatic vessel invasion, lymph node/hepatic/peritoneal metastasis, distant metastasis, and advanced tumour-node-metastasis stage. In the short-term outcome, low pre-operative LCR was an independent predictive factor for post-operative SSI. In the long-term outcome, low pre-operative LCR was an independent prognostic factor for OS and DFS, and prognostic impact of pre-operative LCR were verified in patients with metastatic and non-metastatic gastric cancer. Furthermore, our developed scoring system using lymphocyte and CRP (Lymphocyte-CRP Score; LCS) could also demonstrate all of clinical significance in GC patients, and both of LCR and LCS were significantly correlated with various representative nutrition markers, including BMI, PNI, and albumin, in GC patients.

CONCLUSIONS

Pre-operative LCR and LCS are clinically feasible nutrition-inflammation markers in GC patients. Assessment of lymphocytes and CRP could aid physicians in determining surgical risk and oncological risk, thus facilitating appropriate peri-operative and post-operative management of patients with GC.

Ratio-based staging systems are better than the 7th and 8th editions of the TNM in stratifying the prognosis of gastric cancer patients: A multicenter retrospective study

BACKGROUND

The current and the previous editions of the tumor-node-metastasis (TNM) system for gastric cancer (GC; TNM8 and TNM7) have a high risk of stage-migration bias when the node count after gastrectomy is suboptimal. Hence, they are possibly not the optimal staging systems for GC patients. This study aims to compare the TNM with two systems less affected by the stage-migration bias, namely, the lymph nodes ratio (LNR) and the log odds of positive lymph nodes (LODDS), to assess which one is the best in stratifying the prognosis of GC patients.

METHODS

The sample study included 1221 GC patients. Two 7-cluster staging systems based on the combination of pT categories and LNR and LODDS categories (TLNR and TLODDS) were compared with the two last editions of TNM, using the Akaike information criteria, the Bayesian information criteria, and the receiver operating characteristic (ROC) curve graphs. Further validation on an independent sample of 251 patients was carried out.

RESULTS

The univariable and multivariable analyses and the ROC curves detected an advantage of the TLNR and TLODDS systems over the TNM. The TLNR and TLODDS showed the best accuracy both in the subgroup of patients with ≥16 nodes examined. The results were confirmed in the validation analysis.

CONCLUSIONS

TLNR and TLODDS staging systems should be considered a valid implementation of the TNM for the prognostic stratification of GC patients. If these results are confirmed in further studies, the future implementation of the TNM should consider the introduction of the LNR or the LODDS along with the number of metastatic nodes.

Signet ring cell component, not the Lauren subtype, predicts poor survival: an analysis of 198 cases of gastric cancer

AIM

Prognostic differences between major histologic gastric cancer groups, intestinal and diffuse are uncertain, since cellular components in each of them possibly have different behaviors.

MATERIALS & METHODS

We reviewed 198 gastric cancer patients charts diagnosed from January 2003 to December 2015 in a tertiary hospital. Multivariate Cox proportional survival models were used to evaluate the impact of histologic groups on overall survival.

RESULTS

About a third had the signet-ring cell carcinoma (SRCC). In a comparison of the different histologic subtypes, SRCC had the worst prognosis of all. The median durations of survival for patients with stage III and stage IV were 19.7 and 7.7 months, respectively.

CONCLUSION

Signet-ring cell component seem to have a relevant role in defining prognosis for gastric cancer.

The high-sensitivity modified Glasgow prognostic score is superior to the modified Glasgow prognostic score as a prognostic predictor for head and neck cancer

Background

There is increasing evidence that the inflammatory indices of modified Glasgow prognostic score (mGPS) and high-sensitivity mGPS (HS-mGPS) play important roles in predicting the survival in many cancer; however, evidence supporting such an association in head and neck cancer (HNC) is scarce.

Materials and Methods

We evaluated the impact of the mGPS and HS-mGPS on the overall survival (OS) in 129 patients with HNC treated at Aichi Cancer Center Central Hospital from 2012-2013. The mGPS was calculated as follows: mGPS of 0, C-reactive protein (CRP) ≤1.0 mg/dl; 1, CRP >1.0 mg/dl; 2, CRP>1.0 mg/dl and albumin <3.5 mg/dl. Regarding the HS-mGPS, the CRP threshold level was set as 0.3 mg/dl. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated by Cox proportional hazard models after adjusting for potential confounders.

Results

The prognosis of HNC worsened significantly as both the mGPS and HS-mGPS increased in a univariate analysis. After adjusting for covariates, the HS-mGPS was significantly associated with the OS (adjusted HR for HS-mGPS of 2 compared to an HS-mGPS of 0 [HR_score2-0] 3.14 [95% CI: 1.23-8.07], P_trend < 0.001), while the mGPS was suggested to be associated with the survival (HR_score2-0 2.37 [95% CI:0.89-6.33], P_trend = 0.145). Even after stratification by clinical covariates, these associations persisted.

Conclusion

We conclude that the HS-mGPS is useful as an independent prognostic factor in HNC.

Prognostic Significance of Platelet-Based Inflammatory Indicators in Patients with Gastric Cancer

BACKGROUND

Thrombocytosis develops in association with malignant tumors and may reflect the inflammation status in cancer patients. This study retrospectively investigated the prognostic significance of two platelet-based inflammatory indicators, the platelet × C-reactive protein multiplier value (P-CRP), and platelet-lymphocyte ratio (PLR), in gastric cancer patients.

METHODS

The 453 enrolled patients had a histopathological diagnosis of gastric adenocarcinoma and underwent curative surgery.

RESULTS

P-CRP correlated significantly with age, tumor size, depth of invasion, lymph node metastasis, and disease stage. A high PLR correlated significantly with tumor size, depth of invasion, lymph node metastasis, lymphatic involvement, venous involvement, and disease stage. In the ROC analysis, the optimal cutoff value of P-CRP and PLR was 3.689 and 173.3, respectively. Five-year survival rates were 62.9 and 82.1% in patients with P-CRP^High (≥3.689) and P-CRP^Low (<3.698), respectively (P < 0.0001). Five-year survival rates were 66.3 and 81.3% in patients with PLR^High (≥173.3) and PLR^Low (<173.3), respectively (P = 0.0022). The prognosis of the P-CRP^High/PLR^High group was significantly worse than that of the P-CRP^High or PLR^High and P-CRP^Low/PLR^Low groups in terms of overall survival (P < 0.0001) and disease-specific survival (P = 0.029). In a multivariate analysis, the combination of P-CRP and PLR was an independent prognostic indicator.

CONCLUSIONS

The combination of P-CRP and PLR may be useful in predicting prognosis in gastric cancer patients.

Postoperative ratio of the maximum C-reactive protein level to the minimum peripheral lymphocyte count as a prognostic indicator for gastric cancer patients

PURPOSE

Inflammation, together with immune and nutritional status, are associated with the progression of various cancer types. We evaluated the prognostic significance of the postoperative ratio (post-CLR) of the maximum C-reactive protein value (post-CRP^Max) to the minimum peripheral lymphocyte count (post-LC^Min) in patients with gastric cancer (GC).

METHODS

The subjects of this retrospective study were 227 patients who underwent curative surgery for histopathologically diagnosed gastric adenocarcinoma.

RESULTS

The 5-year overall survival (OS) rates differed significantly between the post-CLR^High (≥ 152.6) group and the post-CLR^Low (< 152.6) group for all patients (45.0% vs. 68.4%, respectively; P < 0.001). The 5-year disease-specific survival (DSS) rates were also significantly related to post-CLR for all patients, (80.6% vs. 64.3% for the post-CLR^Low and the post-CLR^High groups, respectively; P = 0.002). Among patients without infectious complications, the CLR affected both the 5-year OS rate (48.4% vs. 69.2% for the post-CLR^High and the post-CLR^Low groups, respectively; P = 0.006) and the 5-year DSS rate (80.2% vs. 67.0% for the post-CLR^Low and the post-CLR^High groups, respectively; P = 0.027). Multivariate analysis revealed that post-CLR was an independent prognostic indicator for both the OS and DSS of all patients.

CONCLUSIONS

Our finding show that the post-CLR can help predict the prognosis of GC patients.

The neutrophil-to-lymphocyte ratio prechemotherapy and postchemotherapy as a prognostic marker in metastatic gastric cancer

BACKGROUND/AIMS

Markers of inflammation have been associated with outcomes in various cancers. The purpose of this study was to evaluate whether systemic inf lammatory markers and their f luctuations can predict survival and chemotherapy response in patients with metastatic gastric cancer (mGC).

METHODS

We retrospectively reviewed the records of 502 patients who received first-line palliative chemotherapy for mGC between 2007 and 2013. The neutrophil-to-lymphocyte ratio (NLR) and modified Glasgow prognostic score (mGPS) were assessed before and after chemotherapy to evaluate their association with survival. The NLR values were categorized into two groups based on a cut-off value of 3; mGPS values were classified as high versus low.

RESULTS

High prechemotherapy NLR was significantly associated with poor overall survival on univariate analysis (p = 0.002). On multivariate analysis, high prechemotherapy NLR (hazard ratio, 1.43; p < 0.001) was an independent prognostic factor for poor overall survival. However, the prechemotherapy mGPS was not significantly associated with survival. Continuously high NLR or a shift to high NLR postchemotherapy was associated with poor chemotherapy response as well as survival, while NLR reduction was associated with a good response (linear by linear association, p < 0.001) and a favorable prognosis.

CONCLUSION

Prechemotherapy NLR can be used as a prognostic factor in mGC, while the postchemotherapy NLR value may predict the chemotherapeutic response and prognosis. In contrast, mGPS has limited prognostic utility in mGC.
