Clinical usefulness of C-reactive protein-albumin-lymphocyte (CALLY) index as a prognostic biomarker in patients undergoing surgical resection of pancreatic cancer.

PURPOSE: The C-reactive protein-albumin-lymphocyte (CALLY) index, which simultaneously evaluates the nutritional, immunological, and inflammatory statuses, is a new prognostic biomarker in patients with various cancers; however, no study has reported the clinical significance of the CALLY index in patients with pancreatic cancer. This study aimed to investigate whether the preoperative CALLY index is a prognostic biomarker in patients undergoing surgical resection of pancreatic cancer. METHODS: We retrospectively enrolled 461 patients with pancreatic cancer who underwent surgical resection between January 2013 and December 2022. The overall survival (OS) and relapse-free survival (RFS) rates were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed using Cox proportional hazards regression models. RESULTS: The optimal cut-off value for the preoperative CALLY index was 1.9. In the low CALLY group, patients were older (p = 0.012), more patients underwent pancreaticoduodenectomy (p = 0.002), the median tumor size was larger (p < 0.001), more patients had pathologically confirmed metastatic lymph nodes (p = 0.015) and worse pathological stage (p = 0.015), and fewer patients received adjuvant chemotherapy (p = 0.003). A low CALLY index was associated with decreased OS (22.1 vs. 37.9 months) and RFS (12.4 vs. 16.4 months). Univariate and multivariate analyses showed that the preoperative CALLY index was an independent prognostic factor for OS (p < 0.001) and RFS (p = 0.045). CONCLUSION: The preoperative CALLY index is a prognostic biomarker for both OS and RFS in patients undergoing surgery for pancreatic cancer.

The Clinical Impact of the Systemic Immune-inflammation Index in Esophageal Cancer Patients Receiving Curative Treatment.

BACKGROUND/AIM: The systemic immune-inflammation index (SII) is a calculated biomarker developed to predict the prognosis of malignant tumors. This study evaluated the influence of the SII in patients with esophageal cancer (EC) who underwent curative resection. PATIENTS AND METHODS: Patients who underwent radical esophagectomy and lymph node dissection for EC were enrolled. The SII was calculated as follows: neutrophil count (cell/mm3) × platelet count (cell/mm3 ×103)/lymphocyte count (cell/mm3). The SII, patient characteristics, overall survival (OS), and recurrence-free survival (RFS) were assessed. RESULTS: A total of 180 patients were included in this study. The cutoff value of the SII was set at 500 according to previous studies. Of the 180 patients, 100 were classified into the SII-high group and 80 into the SII-low group. The 3- and 5-year OS rates were 59.0% and 54.0%, respectively, in the SII-high group and 80.0% and 75.0%, respectively, in the SII-low group, showing significant differences between the groups (p=0.001). A multivariate analysis for the OS demonstrated that the SII was an independent prognostic factor (hazard ratio=2.333, 95% confidence interval=1.411-3.860, p<0.001), with similar results obtained for the RFS. Furthermore, hematological recurrence was significantly higher in the SII-high group than in the SII-low group (36.0% vs. 17.5%, p=0.006). CONCLUSION: The preoperative SII was an independent prognostic factor for OS and RFS in patients with EC who underwent curative resection. Thus, the SII can be a useful marker for the treatment and management of EC.

Breakfast Protein Intake of One-third of Daily Requirement Can Maintain Lean Body Mass Post-distal Gastrectomy.

BACKGROUND/AIM: Post-gastrectomy lean body mass (LBM) decrease has a significant negative impact on postoperative survival in patients with cancer. This study investigated the effect of intake of at least one-third of the daily protein requirement at breakfast on the maintenance of LBM in patients during the first month post-gastrectomy. PATIENTS AND METHODS: Among patients with gastric cancer who underwent curative distal gastrectomy between April 2011 and December 2018, without adjuvant chemotherapy, we evaluated 401 patients who had consumed more than the daily protein requirement in the first month postoperatively, using the FFQW82 nutrition intake questionnaire. Patients were divided into those who consumed more (≥1/3 intake group, n=160) and those who consumed less than one-third of the daily protein requirement at breakfast (<1/3 intake group, n=241). We compared the LBM reduction rate at one month postoperatively between groups. Univariate and multivariate analyses were performed to determine clinicopathological factors predicting LBM reduction at one month postoperatively. RESULTS: The LBM reduction rate at one month post-curative distal gastrectomy was significantly higher in the <1/3 intake group than in the ≥1.3 intake group (p=0.01) at breakfast. Multivariate analysis showed that morning protein intake below one-third of the daily requirement independently predicted LBM reduction (odds ratio=1.75, 95% confidence interval=1.14-2.68, p<0.01). CONCLUSION: Consuming at least one-third of the daily protein requirement at breakfast may be effective in maintaining LBM in patients undergoing curative distal gastrectomy. These results may be very important for prognosis, since maintaining LBM influences the continuation of adjuvant chemotherapy and thus survival after curative resection in patients with gastric cancer.

Inflammatory Burden Index Is an Independent Prognostic Factor for Esophageal Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: We hypothesized that the inflammatory burden index (IBI) is a promising biomarker for esophageal cancer (EC) treatment and management. To confirm our hypothesis, we evaluated the prognostic impact of IBI in patients with EC who received curative treatment. PATIENTS AND METHODS: We conducted a retrospective review of medical records and collected data from consecutive patients with EC who underwent curative resection at Yokohama City University between 2005 and 2020. The IBI score was calculated as the C-reactive protein level multiplied by the neutrophil-to-lymphocyte ratio. RESULTS: In total, 180 patients with EC were included in this study. The 3- and 5-year overall survival (OS) rates were 72.9% and 63.4%, respectively, in the IBI-low group, and 38.2% and 32.5% in the IBI-high group (p<0.001). In the multivariate analysis, IBI was identified as a significant prognostic factor for OS [hazard ratio (HR)=2.372; 95% confidence interval CI=1.478-3.806, p<0.001]. In addition, the 3- and 5-year recurrence-free survival (RFS) rates were 52.9% and 47.8%, respectively, in the IBI-low group, and 22.9% and 17.2% in the IBI-high group (p<0.001). In the multivariate analysis, IBI was identified as a significant prognostic factor for RFS (HR=2.484; 95%CI=1.373-4.494, p<0.001). When comparing the recurrence patterns between the IBI-high and IBI-low groups, there were significant differences in lymph node recurrence (46.0% vs. 26.2%, p=0.010) and hematological recurrence (52.0% vs. 18.5%, p<0.001). CONCLUSION: IBI affects both the short- and long-term oncological outcomes. Thus, IBI may be a promising prognostic factor for the treatment and management of EC.

Loss of Skeletal Muscle Mass During Neoadjuvant Chemotherapy for Pancreatic Cancer Is Related to the Continuation of S-1 Adjuvant Chemotherapy After Pancreatectomy.

BACKGROUND/AIM: Although perioperative chemotherapy has improved patient survival, sarcopenia may occur during chemotherapy owing to decreased food intake and physical strength. However, reports on the occurrence of sarcopenia and changes in body composition in patients with pancreatic cancer during neoadjuvant chemotherapy are scarce. This study aimed to determine the effect of changes in skeletal muscle mass during neoadjuvant chemotherapy on the S-1 adjuvant chemotherapy clinical course in patients who underwent perioperative chemotherapy and surgical resection. PATIENTS AND METHODS: We retrospectively enrolled 159 patients with pancreatic cancer who underwent neoadjuvant chemotherapy and surgical resection, followed by S-1 adjuvant chemotherapy. We evaluated changes in skeletal muscle mass during neoadjuvant chemotherapy using abdominal computed tomography and the SliceOmatic software. The association between the rate of change in skeletal muscle mass index (Δ%SMI) during neoadjuvant chemotherapy and the continuation of S-1 adjuvant chemotherapy was investigated. RESULTS: Eighty-eight (55.3%) patients lost skeletal muscle mass (Δ%SMI <0) during neoadjuvant chemotherapy with a significantly low S-1 adjuvant completion rate (p=0.02). Δ%SMI <0 was an independent risk factor for the continuation of S-1 adjuvant chemotherapy (hazard ratio=1.924, 95% confidence interval=1.002-3.695, p=0.049). Moreover, the lower the Δ%SMI, the lower the S-1 continuation rate (p=0.022). CONCLUSION: Loss of skeletal muscle mass during neoadjuvant chemotherapy for pancreatic cancer affected the continuation of S-1 adjuvant chemotherapy after pancreatic resection. Therefore, ameliorating loss of skeletal muscle mass during neoadjuvant chemotherapy should be carefully considered to improve the continuation rate of adjuvant chemotherapy and the survival of patients with pancreatic cancer.

Inflammatory Burden Index Prognostic Impact in Patients With Gastric Cancer After Gastrectomy: A Propensity Score-matched Analysis.

BACKGROUND/AIM: The Inflammatory Burden Index (IBI) has been reported as a novel prognostic indicator in several cancers and diseases. However, research on the IBI in patients with gastric cancer (GC) after gastrectomy is insufficient. This study investigated the utility of the preoperative IBI as a prognostic indicator in patients with GC. PATIENTS AND METHODS: This retrospective study enrolled 459 patients undergoing gastrectomy for GC between 2013 and 2017 at the Kanagawa Cancer Center, Kanagawa, Japan. The IBI was calculated from preoperative blood test data. We evaluated the relationship between the preoperative IBI and clinicopathologic factors, overall survival (OS), and recurrence-free survival (RFS) after gastrectomy for GC, using propensity score matched analysis. RESULTS: Regarding the association between IBI and clinicopathologic features, the high-IBI group was significantly older and had more lymphatic invasion and more progressive pT status than the low-IBI group before propensity score-matched analysis. OS and RFS after curative surgery were significantly lower in patients with a high IBI than in those with a low IBI (77.5% vs. 86.1%; p=0.02 and 74.3% vs. 85.1%; p=0.03, respectively). Multivariate analysis identified high IBI as an independent predictor of both OS and RFS. CONCLUSION: Preoperative IBI may serve as a valuable prognostic indicator for patients undergoing curative gastrectomy for GC.

The Clinical Impact of Hemoglobin, Albumin, Lymphocyte, Platelet (HALP) in Gastric Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: We hypothesized that the hemoglobin, albumin, lymphocyte, and platelet (HALP) score may be a promising marker for the treatment and management of gastric cancer (GC). To test this hypothesis, we evaluated the clinical impact of the HALP score in patients with GC who received curative treatment. PATIENTS AND METHODS: Consecutive patients who underwent curative resection for GC at the Yokohama City University between 2005 and 2020 were selected based on their medical records. The HALP score was calculated as follows: HALP=Hemoglobin (g/l) × albumin (g/l) × lymphocytes (109/l)/platelets (109/l). RESULTS: The 3-year and 5-year overall survival (OS) rates were 88.6% and 85.8%, respectively, in patients with HALP scores of >40, and 70.3% and 57.2% in patients with HALP scores of ≤40. There were significant differences between the groups analyzed (p<0.001). In univariate analysis, age, T status, lymph node metastasis status, HALP score, lymphovascular invasion status, pathological type, and postoperative complication status were identified as significant prognostic factors for OS. In multivariate analysis, the HALP score remained a significant prognostic factor for OS [hazard ratio (HR)=2.679; 95% confidence interval (CI)=1.455-4.934, p=0.002]. Similar results were observed in the analysis of recurrence-free survival. In addition, the HALP score status affects the postoperative clinical course, including the occurrence of postoperative anastomotic leakage and the introduction of postoperative adjuvant chemotherapy. CONCLUSION: The HALP score affects both short- and long-term oncological outcomes. Thus, the HALP score may be a promising prognostic factor for the treatment and management of GC.

Prognostic value of computed tomography­derived skeletal muscle index and radiodensity in patients with gastric cancer after curative gastrectomy.

The association of computed tomography (CT)-derived skeletal muscle index (SMI) and skeletal muscle radiodensity (SMD) with postoperative prognosis in patients with gastric cancer (GC) remains unknown. Therefore, the present study aimed to assess the association between SMI and SMD with 5-year overall survival (OS) and recurrence-free survival (RFS) in patients with GC. SMI and SMD were measured preoperatively in patients who underwent gastrectomy. Patients were categorized into Groups 1 (high SMI and SMD), 2 (high SMI or SMD) and 3 (low SMI and SMD). OS and RFS rates were assessed using Kaplan-Meier analysis and the log-rank test. Among 459 patients, OS and RFS rates were significantly lower in the low-SMD group than in the high-SMD group (OS, 83.4% vs. 88.8%, respectively; P=0.04 and RFS, 80.5% vs. 87.2%, respectively; P=0.02). OS and RFS rates were also significantly lower in Group 3 than in Groups 2 and 1 (P=0.006). Multivariate analysis revealed that a low SMI and SMD (Group 3) was a significant independent prognostic factor for OS [hazard ratio (HR), 2.32; 95% confidence interval (CI), 1.17-4.59; P=0.016] and RFS (HR, 2.28; 95% CI, 1.19-4.37; P=0.013). In summary, low SMI and SMD values may be useful postoperative prognostic indicators for patients with GC.

Global Immune-Nutrition-Information Index Is Independent Prognostic Factor for Gastric Cancer Patients Who Received Curative Treatment.

Background/Aim: The aim of the present study was to evaluate the clinical impact of the Global Immune-Nutrition-Information Index (GINI) in patients with gastric cancer (GC) who received curative treatment and to clarify the potential of the GINI as a biomarker. Patients and Methods: Patients who underwent curative resection for GC at Yokohama City University between 2005 and 2020 were selected based on their medical records. The GINI was calculated as follows: GINI=[C-reactive protein × platelet × monocyte × neutrophil]/[albumin × lymphocyte]. Results: A total of 258 patients were included in this study. Of these, 169 patients were categorized into the GINI-low group and 89 into the GINI-high group using a cut-off value of 1,730. The three- and five-year overall survival (OS) rates were 86.4% and 78.4%, respectively, in the GINI-low group, and 66.4% and 58.3% in the GINI-high group (p<0.001). In a multivariate analysis for OS, the GINI was identified as an independent prognostic factor [hazard ratio (HR)=1.772; 95% confidence interval (CI)=1.053-2.979, p=0.031]. Similar results were observed for RFS. In addition, the GINI affected the perioperative clinical course, including postoperative surgical complications and postoperative adjuvant treatment. Conclusion: The GINI is a promising biomarker for the treatment and management of GC.

The Systemic Immune-inflammation Index Is an Independent Prognostic Factor for Gastric Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: Systemic immune-inflammation index (SII) was developed and evaluated for various malignancies. This study evaluated the clinical impact of the SII in patients with gastric cancer (GC) who received curative treatment. PATIENTS AND METHODS: Patients who underwent curative resection for GC at Yokohama City University between 2005 and 2020 were chosen consecutively based on their medical records. SII was calculated as follows: platelet (cell/mm3 ×103)× neutrophil (cell/mm3)/lymphocyte (cell/mm3). Three measurements were obtained preoperatively. RESULTS: In total, 258 patients were enrolled in this study. Based on the 3- and 5-year survival rates and previous studies, we set the cutoff value of the SII to 550. The 258 patients were classified into the SII-low (n=152) and SII-high (n=106) groups, respectively. The 3- and 5-year overall survival (OS) rates were 82.6% and 78.7%, respectively, in the SII-low group and 74.5% and 61.9%, respectively, in the SII-high group. There were significant differences between the two groups (p<0.001). In the multivariate analysis of factors associated with OS, the SII was identified as an independent prognostic factor (hazard ratio=1.816; 95% confidence interval=1.075-3.069, p=0.026). Similar results were observed for recurrence-free survival. In addition, the incidence of postoperative surgical complications was 30.9% in the SII-low group and 45.2% in the SII-high group (p=0.019). CONCLUSION: The SII was an independent prognostic factor for GC. Thus, the SII may be a promising biomarker for the treatment and management of GC.

Comparison of the Dietary Intake After Gastrectomy Between Male and Female Patients With Gastric Cancer.

BACKGROUND/AIM: This study aimed to investigate the differences in the postoperative dietary intake (DI) loss between men and women after radical resection for early gastric cancer (GC), and to identify effective nutritional support for both sexes. PATIENTS AND METHODS: This prospective, observational study enrolled patients who underwent gastrectomy for GC. DI was assessed using the food frequency questionnaire containing 82 food items (FFQW82) during nutritional counseling before surgery and one and three months postoperatively. RESULTS: The median preoperative DI of all participants was 1,856.3 kcal/day, and DI at 1 and 3 months were 1,532.5 kcal/day and 1,637 kcal/day, respectively. The median preoperative DI was 1805 kcal/day (1,300-2,330 kcal/day) and 1481 kcal/day (1,126-1,957 kcal/day) in men and women, respectively (p<0.0001). The median DI at 1 month was 1627 (1,101-2,195) kcal/day and 1,308 (986-1,915) kcal/day in men and women, respectively (p<0.0001). At 3 months postoperatively, the median DI was 1737 (1,130-2,443) kcal/day in men and 1428 (816-2,005) kcal/day in women (p<0.0001). However, there was no significant difference in the DI loss rate at 1 month (median: -9.7% vs. -9.3%, p=0.765) and 3 months (median: -3.5% vs. -4.8%, p=0.137) between men and women. CONCLUSION: Although the DI loss rate in men and women after gastrectomy for GC was almost similar, the postoperative DI and DI loss differed significantly. Therefore, differences in DI loss after gastrectomy between men and women should be considered while assessing the efficacy of additional nutritional support such as oral nutritional supplements after gastrectomy.

Comparison of Survival Between ypStage and pStage in Gastric Cancer.

BACKGROUND/AIM: In East Asia, the standard treatment for resectable advanced gastric cancer involves gastrectomy and postoperative adjuvant chemotherapy; nevertheless, neoadjuvant chemotherapy is also expected to improve survival rates. However, it remains unclear whether the same criteria can be used to select adjuvant chemotherapy for patients treated with neoadjuvant chemotherapy, or how survival varies between post-chemotherapy pathological Stage (ypStage) and pathological Stage without chemotherapy (pStage). This study evaluated the long-term outcomes of ypStage and pStage in gastric cancers and investigated the optimal intensity of adjuvant chemotherapy for patients who have received preoperative chemotherapy. PATIENTS AND METHODS: From January 2007 to November 2019, 1,585 patients underwent radical gastrectomy for gastric cancer at the Kanagawa Cancer Center. The patient background was adjusted by propensity score matching, and recurrence-free survival was compared between the two groups. In addition, a prognostic factor analysis was conducted for each yp/pStage. RESULTS: The 5-year recurrence-free survival rates for yp/pStage I were 77.1% and 90.9%, respectively, with no significant difference (p=0.342). The 5-year recurrence-free survival rates for yp/pStage II were 50.4% and 69.1%, respectively, with no significant difference (p=0.062). The 5-year recurrence-free survival rates for yp/pStage III were 42.9% and 68.7%, respectively, with a significant difference observed (p=0.016). In the prognostic factor analysis for each stage, the presence or absence of preoperative chemotherapy was selected as an independent prognostic factor for yp/pStage I [hazard ratio (HR)=17.72; p=0.001] and yp/pStage II (HR=2.655, p=0.003). CONCLUSION: ypStage tends to have a worse prognosis than pStage, and further development of multidisciplinary treatment is necessary.

A propensity­matched analysis of the prognostic value of advanced lung cancer inflammation index in patients with gastric cancer after curative resection.

The prognostic significance of inflammation, immune response and nutritional status in patients with cancer is well-documented. The advanced lung cancer inflammation index (ALI) has emerged as a novel prognostic indicator, reflecting both inflammation and nutritional status. This study aimed to assess the prognostic relevance of preoperative ALI in patients with gastric cancer (GC). Data of 459 patients who underwent curative gastrectomy for GC between December 2013 and November 2017 at the Kanagawa Cancer Center (Yokohama, Japan) were retrospectively analyzed. Preoperative ALI was calculated from blood tests. Patients were divided into the high- and low-ALI groups. This study investigated the association between preoperative ALI, clinicopathological features, overall survival (OS) and relapse-free survival (RFS) after propensity-matched analysis. Comparative analysis revealed that patients in the low-ALI group tended to be older, were predominantly female, had lower body mass index and had a higher incidence of lymphatic invasion compared with those in the high-ALI group before propensity-matched analysis. Notably, the low-ALI group exhibited significantly reduced OS and RFS post-gastrectomy (85.5% vs. 93.8%, P=0.01; and 82.1% vs. 91.8%, P=0.02, respectively). Multivariate analysis identified low ALI as an independent prognostic factor for both OS and RFS. In conclusion, preoperative ALI could provide a valuable prognostic tool for patients with GC undergoing curative resection, offering insights into patient survival outcomes based on their inflammatory and nutritional status.

The Clinical Impact of the Pretreatment Albumin to Fibrinogen Ratio in Esophageal Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: The albumin to fibrinogen ratio (AFR) has been identified as a promising prognostic marker for some malignancies. The aim of the present study was to evaluate the clinical impact of AFR in esophageal cancer patients who received curative resection. PATIENTS AND METHODS: The present study included 123 patients who underwent curative treatment for esophageal cancer between 2005 and 2020. The prognosis and clinicopathological parameters were compared between patients with high and low AFRs. RESULTS: The overall survival (OS) stratified by each clinical factor was compared using the log-rank test, and a significant difference was observed when using a pretreatment AFR of 1.23. When comparing the patient backgrounds between the high-AFR (AFR ≥12.3) and low-AFR (AFR<12.3) groups, significant differences were noted in the pathological T status. The high-AFR group had significantly higher OS rates at 3 years (70.8%) and 5 years (59.3%) after surgery in comparison to the low-AFR group (46.6% and 37.4%, respectively). Univariate and multivariate analyses for OS showed that the AFR was a significant prognostic factor. In addition, when comparing the site of first recurrence, a marginally significant difference was noted in hematological recurrence. CONCLUSION: The AFR is a significant risk factor in patients with esophageal cancer, holding promise as a valuable prognostic factor.

The Prognostic Immune and Nutritional Indices Are Independent Prognostic Factors for Esophageal Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: Recently, the prognostic immune and nutritional index (PINI) was developed and reported to be a promising nutritional and inflammatory prognostic marker. The aim of the present study was to clarify the clinical impact of the PINI for esophageal cancer patients who received curative treatment. PATIENTS AND METHODS: We conducted a retrospective review of medical records and collected data on consecutive esophageal cancer patients who underwent curative resection at Yokohama City University between 2005 and 2020. The PINI was calculated by dividing the serum ALB concentration (g/dl) by the serum monocyte concentration, both of which were measured before surgery. RESULTS: A total of 180 patients were included in this study. The cutoff value of the PINI was 3.0 in the present study. The 3- and 5-year overall survival rates were 45.2% and 33.5%, respectively, in the PINI-low subgroup, and 69.1% and 61.8%, respectively, in the PINI-high subgroup. A multivariate analysis demonstrated that the PINI was an independent prognostic factor for overall survival (hazard ratio=2.091, 95% confidence interval=1.287-3.399, p=0.003). Similar results were observed for recurrence-free survival. When comparing the sites of recurrence between the two groups, the incidence of hematological recurrence was significantly greater in the PINI-low subgroup compared to the PINI-high subgroup (46.8% vs. 21.1%, p<0.001). CONCLUSION: The PINI is a promising nutritional and inflammatory marker for esophageal cancer patients. The PINI might be a useful marker for the treatment and management of esophageal cancer patients.

The Clinical Impact of the Prognostic Immune and Nutritional Index in Gastric Cancer Patients Who Received Curative Treatment.

BACKGROUND/AIM: The prognostic immune and nutritional index (PINI) was developed and reported as a promising prognostic factor. This study aimed to clarify the clinical impact of the PINI in gastric cancer (GC) patients who received curative treatment. PATIENTS AND METHODS: Patients who underwent curative resection for GC at Yokohama City University between 2005 and 2020 were selected based on their medical records. The PINI was calculated by dividing the serum albumin concentration (g/dl) by the serum monocyte concentration. Both measurements were performed prior to surgery. RESULTS: A total of 262 patients were included in this study. Based on the 3- and 5-year overall survival (OS), we set the cutoff value of the PINI at 3.4 in the present study. The 3- and 5-year OS rates were 69.0% and 66.1%, respectively, in the PINI-low group and 90.5% and 82.8% in the PINI-high group. There were significant differences between the two groups (p<0.001). A multivariate analysis of factors associated with OS identified PINI as an independent prognostic factor (hazard ratio=1.996; 95% confidence interval=1.096-3.636, p=0.024). Similar results were observed for RFS. In addition, the PINI status affected the recurrence pattern, postoperative anastomotic leakage, and the introduction of postoperative adjuvant chemotherapy. CONCLUSION: The PINI is a promising nutritional and inflammatory marker for patients with GC and might be a useful marker for the treatment and management of patients with GC.

The CRP-albumin-lymphocyte (CALLY) Index Is an Independent Prognostic Factor for Gastric Cancer Patients who Receive Curative Treatment.

BACKGROUND/AIM: The CRP-albumin-lymphocyte (CALLY) index is a promising biomarker. We clarified the clinical impact of the CALLY index in gastric cancer patients who received curative treatment. PATIENTS AND METHODS: Consecutive patients who underwent curative resection for gastric cancer at Yokohama City University from 2005 to 2020 were selected based on medical records. The CALYY index was calculated as follows: serum ALB level (g/dl) × lymphocyte count (cells/µl)/C-reactive protein (mg/dl) ×104 Results: Two hundred fifty-nine patients were included in the present study. The three- and five-year overall survival (OS) rates were 64.8% and 57.0%, respectively, in the CALLY index-low group, and 86.2% and 78.2%, respectively, in the CALLY index-high group. There were significant differences between the two groups. A multivariate analysis demonstrated that the CALLY index was an independent prognostic factor for overall survival (hazard ratio=1.791; 95% confidence interval=1.067-3.009; p=0.028). When comparing the perioperative clinical course between the CALLY index-low and CALLY index-high groups, there were significant differences in postoperative surgical complications and adjuvant chemotherapy. CONCLUSION: The CALLY score was an independent prognostic factor for patients with gastric cancer. Our results suggest that the CALLY index is a promising tool for assessing inflammation and nutritional status in patients undergoing gastric cancer treatment and management.

Clinical Impact of Nutrition and Inflammation Assessment Tools in Colorectal Cancer Treatment.

For resectable colorectal cancer (CRC), the standard treatment is perioperative adjuvant treatment and complete resection. For unresectable CRC, the standard treatment is systemic chemotherapy. The detection of promising biomarkers is necessary for optimizing the management of CRC and improving patient survival. If physicians can detect useful biomarkers, patients with CRC may benefit from more aggressive or less toxic treatment. Recent studies have shown that the inflammatory and nutritional status both influence the short and long-term oncological outcomes of patients with CRC during perioperative and/or chemotherapy. The utility of several tools for the evaluation of the inflammation and nutritional status has been reported. The introduction of such tools in the management of CRC could have a beneficial impact on postoperative surgical complications or adverse events of chemotherapy. An understanding of the characteristics of each of these evaluations is necessary for their introduction in daily clinical practice. The present report summarizes the background and current status of nutrition and inflammation evaluation tools and future perspectives on their application in the management of patients with CRC.

Clinical Impact of Preoperative Prognostic Nutritional Index in Surgical Patients With Pancreatic Cancer Treated With Perioperative Adjuvant Chemotherapy.

BACKGROUND/AIM: The prognostic nutritional index (PNI) is used as a marker to evaluate the nutritional and immunological status of patients with various cancers. This study aimed to investigate whether preoperative PNI is a prognostic factor in patients with pancreatic cancer who underwent perioperative adjuvant chemotherapy and surgical resection. PATIENTS AND METHODS: We retrospectively enrolled 232 pancreatic cancer patients who underwent surgical resection with perioperative adjuvant chemotherapy between January 2013 and December 2022. Overall survival (OS) and relapse-free survival (RFS) rates were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed using the Cox proportional hazards regression models. RESULTS: The optimal cutoff value for the preoperative PNI was 44.3 in the present study. PNI <44.3 was associated with older age (p<0.001) and affected the clinical course of postoperative adjuvant chemotherapy. The PNI <44.3 had an important influence on the decreased OS (25.1 vs. 39.0 months) and RFS (13.1 vs. 22.8 months). In univariate and multivariate analyses, the preoperative PNI was an independent prognostic factor for OS [hazard ratio (HR)=1.682, 95% confidence interval (CI)=1.059-2.673, p=0.028] and RFS (HR=1.559, 95% CI=1.037-2.344, p=0.033). CONCLUSION: Preoperative PNI is a prognostic factor for both OS and RFS in patients with pancreatic cancer who underwent perioperative adjuvant chemotherapy and surgical resection. This study suggests that a low PNI may cause a lack of full-dose adjuvant chemotherapy, leading to recurrence and resulting in a poor prognosis for surgical pancreatic cancer patients treated with perioperative adjuvant chemotherapy.

Clinical Impact of the Lymphocyte-to-Monocyte Ratio in Patients With Gastric Cancer who Received Curative Treatment.

BACKGROUND/AIM: The aim of the present study was to evaluate the clinical impact of the pretreatment lymphocyte-to-monocyte ratio (LMR) on both short- and long-term oncological outcomes in patients with resectable gastric cancer (GC). PATIENTS AND METHODS: The patients were chosen based on our medical records from consecutive cases of curative resection for GC performed at Yokohama City University from 2005 to 2020. The LMR was calculated as the lymphocyte count divided by the monocyte count measured before surgery. RESULTS: The three- and five-year overall survival (OS) rates were 63.1% and 57.4%, respectively, in the low-LMR subgroup and 86.4% and 77.5%, respectively, in the high-LMR subgroup. According to multivariate analysis, the LMR was an independent prognostic factor for OS [hazard ratio (HR)=1.926, 95% confidence interval (CI)=1.143-3.245, p=0.014]. In addition, the three- and five-year RFS rates were 54.4% and 50.7%, respectively, in the low-LMR subgroup and 84.0% and 76.0% in the high-LMR subgroup. According to multivariate analysis, the LMR was an independent prognostic factor for OS (HR=2.031, 95%CI=1.266-3.258, p=0.003). When comparing the sites of recurrence between the low-LMR and high-LMR groups, there were significant differences in hematologic recurrence, lymph node recurrence, and peritoneal recurrence. CONCLUSION: Preoperative LMR might be a promising tool for the treatment and management of GC.
