Abstract Background Intraductal oncocytic papillary neoplasm (IOPN), previously classified as a subtype of intraductal papillary mucinous neoplasm (IPMN), has been described as an independent disease by the WHO since 2019. IOPN is a rare tumor, with few reported cases. Herein, we report a case of resected non-invasive IOPN that formed a lesion protruding toward the duodenum from the accessory papilla. Case presentation An 80-year-old woman was referred to our hospital because of a giant mass in the pancreatic head detected on abdominal contrast-enhanced computed tomography (CT) performed for a close examination of a mass in the right breast. CT revealed a 90-mm-sized tumor with a mixture of solid and cystic components, with contrast enhancement in the pancreatic head, and a dilated main pancreatic duct. Esophagogastroduodenoscopy revealed a semi-circumferential papillary tumor protruding toward the duodenal lumen, which did not protrude from the papilla of Vater. Transpapillary biopsy led to a preoperative diagnosis of IPMN with an associated invasive carcinoma. As there were no distant metastasis, open subtotal stomach-preserving pancreaticoduodenectomy was performed. Analysis of the surgical specimen and histopathological examination revealed that the tumor was an IOPN that protruded toward the duodenal mucosa from the accessory papilla while replacing the duodenal mucosa with no obvious stromal invasion. Conclusion IOPN is a rare and poorly recognized tumor with few reported cases. There have been no reports describing IOPN forming a protruding lesion toward the duodenum from the accessory papilla. Therefore, further accumulation of cases such as this one is important to advance the study of IOPN.

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. [ABSTRACT FROM AUTHOR]

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.

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.

Background/Aim: The aim of the present study was to evaluate the clinical impact of the Global Immune-NutritionInformation 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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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.

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. [ABSTRACT FROM AUTHOR]

Background/Aim: Recently, preoperative inflammatory, immune, and nutritional statuses have attracted attention as prognostic factors in post-curative gastrectomy patients with gastric cancer (GC). The usefulness of the Creactive protein-albumin-lymphocyte (CALLY) index as a prognostic factor in patients with various cancers, has been reported. However, reports on the clinical significance of the CALLY index in patients with GC after gastrectomy remain inadequate. In this prospective study, we focused on the preoperative CALLY index and investigated its usefulness as a prognostic factor in patients with GC. Patients and Methods: This study included 459 patients who underwent gastrectomy for GC between December 2013 and November 2017 at Kanagawa Cancer Center, Kanagawa, Japan. The preoperative CALLY index was calculated based on the preoperative blood test data. Patients were divided into high- and low-CALLY groups. The associations of the preoperative CALLY scores with clinicopathological factors, overall survival (OS), and recurrence-free survival (RFS) after gastrectomy for GC were evaluated. Results: The low-CALLY group was significantly older, had higher venous invasion, and a more progressive pStage than did the high-CALLY group. OS and RFS after gastrectomy in the low-CALLY group were significantly worse than those in the high-CALLY group (77.9% vs. 88.9%; p<0.001 and 73.8% vs. 87.1%; p<0.001, respectively). In the multivariate analysis, a low CALLY score was an independent prognostic factor of worse OS and RFS. Conclusion: Preoperative CALLY levels may be a useful prognostic predictor in patients with GC after curative gastrectomy. [ABSTRACT FROM AUTHOR]

Background/Aim: The albumin-globulin ratio (AGR) is a useful biomarker for predicting postoperative complications and a poor prognosis in patients with various types of cancer and can be evaluated without invasive testing or surgery. In this study, we aimed to evaluate the usefulness of the AGR in predicting the short- and long-term prognoses of patients with gastric cancer who underwent radical resection at our institution. Patients and Methods: This study is a retrospective cohort analysis in which eligible patients were selected from the medical records of patients who underwent radical resection for gastric cancer at Yokohama City University from 2000 to 2020 and their medical records were reviewed. A total of 240 patients with gastric cancer were classified into high-AGR (>1.57) and low-AGR (=1.57) groups and their overall survival (OS), recurrence-free survival (RFS), and postoperative complication rates were compared. Results: Of the total 240 patients, 87 were classified into the high AGR group and 153 were classified into the low AGR group; the incidence of postoperative complications in the two groups did not differ to a statistically significant extent (34.4% vs. 39.2%, p=0.491). The long-term findings showed that the 5-year OS and RFS rates were significantly better in the high AGR group [84.0% vs. 64.8% (p=0.005), 80.0% vs. 61.9% (p=0.015), respectively]. Conclusion: Preoperative low AGR is a risk factor for OS and DFS in patients with gastric cancer who undergo surgery. The AGR may be a useful biomarker that can be applied as a prognostic indicator for patients with gastric cancer. [ABSTRACT FROM AUTHOR]

Background/Aim: Gastric cancer is a common cause of cancer death worldwide, especially in East Asia. This study evaluated the impact of preoperative modified Neutrophil-Platelet Score (mNPS) on the survival and recurrence of patients with resectable gastric cancer. Patients and Methods: The study analyzed 168 patients who underwent curative gastrectomy and subsequently received adjuvant treatment for gastric cancer between 2015 and 2021. Univariate and multivariate analyses were performed to identify the risk factors for overall survival (OS) and recurrence-free survival (RFS). Results: Patients were divided into two groups: 76 patients with an mNPS of 0 were classified into the low-mNPS group, whereas 92 patients with an mNPS of =1 were classified into the high-mNPS group. The 3- and 5-year OS rates in the low-mNPS group were 65.6% and 56.2%, respectively, and those in the high-mNPS group were 45.3% and 36.9%, respectively. The difference in OS between the two groups was statistically significant (p=0.007). The 3- and 5-year RFS rates in the low-mNPS group were 45.6% and 38.7%, respectively, whereas those in the highmNPS group were 33.4% and 28.1%, respectively. The difference in RFS between the two groups was statistically significant (p=0.043). A multivariate analysis showed that the mNPS was a significant independent prognostic factor for OS and RFS. Conclusion: mNPS is a potential prognostic marker for patients with gastric cancer who underwent curative gastrectomy. Higher mNPS values were associated with lower 3- and 5-year OS and RFS rates, indicating a potential correlation between elevated mNPS and worse outcomes. [ABSTRACT FROM AUTHOR]

Background/Aim: This study aimed to evaluate the clinical impact of the Naples Prognostic Score (NPS) in patients with gastric cancer and to clarify the potential of the NPS as a nutritional and inflammation evaluation system. Patients and Methods: This study included 158 patients who underwent curative treatment for gastric cancer between 2005 and 2020. The prognosis and clinical pathological parameters of the high-NPS (NPS >2) and low-NPS (NPS=0, 1) groups were analyzed. Results: The overall survival (OS) rates at 3 and 5 years were 86.7% and 77.7%, respectively, in the low-NPS group and 55.4% and 47.4%, respectively, in the high-NPS group. There were significant differences in OS between the two groups. Uni- and multivariate analyses demonstrated that the NPS was an independent prognostic factor for OS (HR=2.495, 95%CI=1.240-5.451). In addition, the 3- and 5-year recurrence-free survival (RFS) rates were 82.1% and 76.0%, respectively, in the NPS-low group, and 43.8% and 36.6% in the NPS-high group. Univariate and multivariate analyses demonstrated that the NPS was an independent prognostic factor for RFS (HR=2.739, 95%CI=1.509-4.972). When the first site of recurrence was compared between the low-NPS group and high-NPS group, there were significant differences in peritoneal recurrence (8.7% vs. 34.3%, p=0.001) and hematologic recurrence (5.6% vs. 21.9%, p=0.004). Conclusion: The NPS was a significant prognostic factor in patients with gastric cancer who received curative treatment. The NPS may be a promising biomarker for the treatment and management of gastric cancer. [ABSTRACT FROM AUTHOR]

Background/Aim: Radical resection after preoperative adjuvant chemotherapy (NAC) is a standard treatment for patients with locally advanced esophageal squamous cell carcinoma (LAESCC), but its outcome remains unsatisfactory. In order to develop a personalized treatment program for LAES, we herein compared the survival prediction utility of five pre-NAC nutritional, inflammatory, and immune indexes in patients with LAESCC. Patients and Methods: We evaluated the survival of 203 patients with LAESCC who underwent radical resection after NAC from January 2011 to September 2019 for the following representative pre-NAC nutritional, inflammatory, and immune indices: modified Glasgow Prognostic Score, Prognostic Nutritional Index, C-reactive protein/albumin ratio, serum neutrophil/lymphocyte ratio, and Geriatric Nutrition Risk Index (GNRI) were evaluated for their impact on survival. Results: Of the five indices, GNRI was the best predictor of survival as determined by the area under the curve (p<0.05). When patients were divided into three groups according to the nutritional risk assessment of Bouillanne et al. using the pre-NAC GNRI, the 5-year overall survival (OS) and recurrence-free survival (RFS) were significantly stratified (p<0.001). On multivariate analysis, the GNRI independently identified a poor OS group [group 1: hazard ratio (HR)=2.598, p=0.002; group 2: HR=6.257, p<0.001] and a high recurrence risk group (group 1: HR=1.967, p=0.016; group 2: HR=4.467, p<0.001). Conclusion: In patients with LAESCC, GNRI may be the most accurate, reliable, and useful prognostic factor among the five major systemic inflammatory and nutritional indices. [ABSTRACT FROM AUTHOR]

Background/Aim: Based on gastric shape, patients with gastric cancer can be divided into storage (hook-shaped and ptotic stomach) and reverse outflow (steerhorn and cascade stomach) groups. In patients with gastric cancer, postoperative loss of lean body mass (LBM) is associated with a poor prognosis. This study investigated the influence of preoperative gastric shape on LBM loss 1 month after curative distal gastrectomy. Patients and Methods: Between May 2011 and May 2019, we enrolled 487 patients with pathological stage IA/IB/IIA gastric cancer who underwent curative distal gastrectomy and did not receive adjuvant chemotherapy. Patients were divided into storage (n=370) and outflow (n=117) groups according to whether barium was stored in the stomach during the preoperative fluoroscopic examination. Clinicopathological features, LBM 1 month after gastrectomy, and predictors of postoperative LBM loss were compared between the groups using multivariable logistic regression. Results: The incidence of >5% LBM loss and >7.5% body weight loss 1 month postoperatively were significantly higher in the storage group than in the outflow group (p=0.003 and p=0.009, respectively). Multivariable analysis revealed that gastric shape [odds ratio (OR)=3.30, 95% confidence interval (CI)=1.95-5.59, p<0.001], male sex (OR=3.20, 95% CI=2.07-4.96, p<0.001), and Roux-en-Y reconstruction (OR=1.69, 95% CI=1.08-2.64, p=0.02) were independent predictors of LBM loss. Postoperative dietary problems, especially dumping syndrome, diarrhea, and reflux were more common in the storage group (p<0.001). Conclusion: Gastric shape may be a useful independent predictor of postoperative LBM loss in patients with gastric cancer undergoing distal gastrectomy. [ABSTRACT FROM AUTHOR]

Background/Aim: Radical esophagectomy after preoperative neoadjuvant chemotherapy (NAC) is the standard treatment for locally advanced esophageal squamous cell carcinoma (ESCC). However, careful treatment selection is required when considering organ function in elderly patients. Prealbumin, a rapid turnover protein, is a short-term dynamic nutritional index, and its relationship with long-term postoperative survival in various cancers has been previously reported. However, the association between serum prealbumin level before NAC and survival in elderly patients remains unclear. This study investigated the clinical significance of prealbumin level measurement before NAC in elderly patients with locally advanced ESCC who underwent surgery after NAC. Patients and Methods: Eighty patients aged =65 years diagnosed with cStage II/III ESCC and undergoing radical esophagectomy after cisplatin and 5-fluorouracil therapy as NAC, were included. The cutoff value of the serum prealbumin level before NAC was set at 18.2 mg/dl using receiver operating characteristic curve analysis, and postoperative complications, recurrence, and overall survival were compared between the low and high prealbumin groups. Results: There were no differences in patient background, clinicopathological characteristics, postoperative complications, or recurrence-free survival between the two groups. Overall survival (OS) was significantly worse in the low prealbumin group than in the high prealbumin group (5-year survival, 33.3% vs. 67.0%; p=0.0341). Furthermore, on univariate and multivariate analysis, low prealbumin level was an independent poor OS factor (p=0.036). Conclusion: In elderly patients with locally advanced ESCC, serum prealbumin level before NAC may be a useful prognostic factor and may be important in selecting a treatment strategy that considers individual organ function.

Background/Aim: A new modified nutritional risk index (mNRI), calculated using serum albumin (g/l)+body mass index (BMI) [weight (kg_/height² (m²)], is a good predictor of postoperative complications and cancer survival. However, no study has used this index in patients with gastric cancer (GC). Therefore, we aimed to investigate the clinical significance of the preoperative mNRI values in patients with GC who underwent curative resection. Patients and Methods: We examined 449 patients who underwent curative resection for GC at Kanagawa Cancer Center between 2013 and 2017. The mNRI cutoff value obtained using a receiver operating characteristic analysis was 23.31. Patients were divided into high and low mNRI groups according to the cutoff value, and the clinicopathological characteristics and outcomes were compared between the two groups. Results: In terms of clinicopathological characteristics, the high mNRI group had a higher proportion of men, higher BMI, and a higher proportion of patients with American Society of Anesthesiologists physical status class 2/3 compared with the low mNRI group; the low mNRI group had significantly worse 5-year recurrence-free survival (RFS) and overall survival (OS) than the high mNRI group (OS, p=0.005) (OS, p=0.006; RFS, p=0.018) did. In the multivariate analysis, a low mNRI was an independent predictor of OS (p=0.006) and RFS (p=0.013). Conclusion: Preoperative mNRI may be a useful recurrence and prognostic biomarker in patients with GC who have undergone curative resection. [ABSTRACT FROM AUTHOR]

Background/Aim: The platelet-to-lymphocyte ratio (PLR) is a promising prognostic marker in some malignancies. The present study evaluated the clinical impact of the PLR in patients with gastric cancer who underwent curative resection. Patients and Methods: This study included 258 patients who underwent curative treatment for gastric cancer between 2005 and 2020. The prognosis and clinicopathological parameters between the high- and low- PLR statuses were analyzed. Results: The overall survival (OS) stratified by each clinical factor was compared using the log-rank test, and a significant difference was observed using a pretreatment PLR of 150. When comparing the patient backgrounds between the high-PLR (PLR≥150) and low-PLR (PLR<150) groups, there were no significant differences between the two groups. The OS rates at 3 and 5 years after surgery were significantly higher at 70.8% and 60.4%, respectively, for the high-PLR group than at 83.6% and 79.7%, respectively, for the low-PLR group. Univariate and multivariate analyses of the OS showed that the PLR was a significant prognostic factor. In addition, when comparing the first recurrence sites, there were significant differences in peritoneal recurrence. Conclusion: The PLR is a significant risk factor for gastric cancer, making it a promising prognostic factor for patients with gastric cancer. [ABSTRACT FROM AUTHOR]

Background/Aim: We investigated the influence of the preoperative Oral Health Assessment Tool (OHAT) score on the outcomes of patients with esophageal cancer after curative surgery. Patients and Methods: This study included 90 patients with esophageal cancer who underwent curative surgery and who were screened with the OHAT between 2008 and 2021. The OHAT consists of eight categories with three possible scores. The risk factors for 5- year overall survival (OS) and recurrence-free survival (RFS) were identified. Results: Patients were divided into healthy (n=42) and unhealthy (n=48) groups. The OHAT score was identified as a significant risk factor for postoperative pneumonia (11.9% vs. 43.8%, p=0.001) and postoperative hospital stay (20.5 days vs. 50.1 days, p=0.042). The 5-year OS rate after surgery was 71.2% in the healthy group and 43.2% in the unhealthy group, which was a significant difference (p=0.015). A multivariate analysis showed that a high OHAT score was a significant independent factor for 5-year OS (p=0.034). Conclusion: The OHAT score was a useful prognostic marker in patients who underwent curative surgery for esophageal cancer. To improve the oncological outcomes of patients with esophageal cancer, it is necessary to carefully plan perioperative oral/dental care using the OHAT score. [ABSTRACT FROM AUTHOR]

Background/Aim: Clinical staging in the eighth edition of the Union for International Cancer Control TNM classification (TNM8) is reported to predict the prognosis of patients with gastric cancer. However, there have been no reports on using the TNM8 for prognostic stratification of patients with adenocarcinoma of the esophagogastric junction (AEG). This study aimed to investigate whether it was possible to stratify the prognosis of patients who underwent curative surgery for Siewert type II/III AEG according to the TNM8 clinical stage (cStage). Patients and Methods: This study included patients with Siewert type II/III AEG who underwent curative surgery between 2000 and 2019 at Kanagawa Cancer Center. Those who received neoadjuvant chemotherapy were excluded. We investigated the survival of patients with AEG of each TNM8 cStage. Results: This study included 138 patients, among whom 102 (74%) had Siewert type II and 36 (26%) had Siewert type III AEG. A total of 50, 38, 43, and seven patients were classified with cStage I, II, III, and IV, respectively. The median duration of follow-up of the survivors was 54.7 months. The 5-year overall survival rate of the entire cohort was 65.8%, whereas for patients with cStage I, II, III and IV was 81.6%, 69.0%, 54.3% and 14.3%, respectively. The hazard ratio with reference to cStage I was 1.83, 3.07, and 8.13 for cStage I, III, and IV, respectively, increasing in a stepwise manner. Conclusion: TNM8 Clinical staging is able to stratify the prognosis of patients with Siewert type II/III AEG. [ABSTRACT FROM AUTHOR]

Background/Aim: The prognostic nutritional index (PNI) has been reported as an immunonutritional index that can easily evaluate nutritional status and immunocompetence from blood tests. The purpose of this study was to investigate the usefulness of PNI as a prognostic factor in postoperative gastric cancer patients. Patients and Methods: In this retrospective cohort study, we evaluated 258 patients with pStage I-III gastric cancer who underwent radical resection at Yokohama City University Hospital, from 2015 to 2021. To examine the association with prognosis, we analyzed clinicopathological factors including PNI (<47/=47), age (<75/=75), sex (male/female), depth (pT1/=pT2), lymph node metastasis (pN+/pN-), lymphatic invasion (ly+/ly-), vascular invasion (v+/v-), histological type (enteric/spread) and postoperative complications. Results: In univariate analysis, PNI (p<0.001), depth of tumor invasion (p<0.001), lymph node involvement (p<0.001), age (p=0.002), lymphatic invasion (p<0.001), vascular invasion (p<0.001), and postoperative complications (p=0.003) were associated with overall survival. In multivariate analysis, PNI (HR=2.100, 95% confidence interval 1.225-3.601, p=0.007), tumor invasion, lymph node metastasis, and postoperative complications were shown as poor prognostic factors for overall survival. Conclusion: PNI is an independent prognostic factor for overall and recurrence-free survival in postoperative gastric cancer patients. PNI could be implemented in clinical practice to identify patients at higher risk for poor outcomes. [ABSTRACT FROM AUTHOR]
