RESUMO
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.
RESUMO
BACKGROUND/AIM: The sex-specific effect of the visceral-to-subcutaneous fat ratio (VSR) before gastrectomy on postoperative survival in patients with gastric cancer (GC) remains unclear. This study measured the preoperative VSR in patients with GC and analyzed its relationship with 5-year overall survival (OS) and relapse-free survival (RFS) by sex. PATIENTS AND METHODS: This prospective study included 540 patients with GC undergoing gastrectomy. Preoperative visceral and subcutaneous fat volumes were measured using computed tomography, and the VSR was calculated. A cutoff value for the VSR was established using 5-year survival data, and its association with survival was analyzed using the Kaplan-Meier method, log-rank tests, and multivariate regression analysis. RESULTS: Among the 459 patients analyzed (300 males and 159 females), OS and RFS were significantly lower in the low-VSR group than in the high-VSR group in males (OS: 76.2% vs. 88.1%, p=0.01; RFS: 74.6% vs. 86.0%, p=0.02). In females, no difference in OS was observed between the groups, whereas the high-VSR group had significantly lower RFS than that of the low-VSR group (RFS: 74.7% vs. 88.9%, p=0.01). Multivariate analysis showed that a low VSR was an independent poor predictor of OS in males and a high VSR was an independent poor predictor of RFS in females. CONCLUSION: In patients with GC, the sex-dependent preoperative VSR was a potentially useful predictor of postoperative survival.

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: Endoscopic submucosal dissection (ESD) followed by chemoradiotherapy (CRT) has become a promising treatment modality in the management of early-stage superficial esophageal squamous cell carcinoma (SESCC). However, radiotherapy often leads to significant adverse events (AEs), including cardiopulmonary toxicity, limiting the delivery of this treatment modality. This study aimed to evaluate the efficacy of reduced-volume radiotherapy and dose-dense chemotherapy in mitigating AEs for high-risk SESCC following ESD. PATIENTS AND METHODS: We retrospectively analyzed patients treated with customized CRT after ESD between 2014 and 2023. RESULTS: Thirty-nine consecutive patients were identified. The median follow-up period was 63.4 months (range=8.3-99.8 months). All patients completed CRT, with a low incidence (3%) of grade ≥3 nonhematologic AEs. Thirteen patients (33%) had a recurrence: 10 local, one regional, and two distant. The 5-year overall and disease-free survival rates were 77% and 64%, respectively. A positive vertical resection margin was identified as a prognostic factor associated with survival. CONCLUSION: Our novel approach of combining ESD with customized reduced-volume radiotherapy and dose-dense chemotherapy shows promise in providing favorable oncologic outcomes and a safer nonsurgical strategy for high-risk SESCC. Specifically, this regimen minimized cardiopulmonary toxicity without compromising therapeutic efficacy. More aggressive adjuvant therapy may be required for patients with positive vertical resection margins after ESD.

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.
RESUMO
BACKGROUND/AIM: This study aimed to compare dietary intake (DI) after gastrectomy for gastric cancer between patients with (C group) and without (NC group) postoperative surgical complications. PATIENTS AND METHODS: This prospective observational study enrolled patients who underwent gastrectomy for gastric cancer. DI was assessed using a food frequency questionnaire with 82 food items (FFQW82) during nutritional counseling before surgery and at one and three months after surgery. RESULTS: A total of 225 patients participated in this study. Of the 225 patients, 193 had no postoperative complications, and 32 had postoperative complications (Clavien-Dindo grade ≥2). The median DI at 1 month postoperatively was 1508 kcal/day in the NC group and 1,470.5 kcal/day in the C group (p=0.175). The median DI at 3 months postoperatively was 1,623 kcal/day in the NC group and 1575 kcal/day in the C group (p=0.473). There was a significant difference between the NC and C groups in the rate of decrease in DI at one month (median: -8.44% vs. -15.37%, p=0.032) and at three months postoperatively (median: -3.58% vs. -6.12%, p=0.038). CONCLUSION: There was a statistically significant difference in the rate of decrease in DI after gastrectomy between the C and NC groups at 1 and 3 months postoperatively. Our results suggest that patients with postoperative surgical complications require additional nutritional treatment for decreased DI.

BACKGROUND/AIM: The tryptophanyl-tRNA synthetase 1 gene (WARS1), encodes a tryptophan-tRNA synthetase involved in the amino acidification of tryptophan-tRNA and has been reported to be involved in cancer cell growth, metastasis promotion, and drug resistance in a variety of cancers. This study investigated the clinical significance of WARS1 expression as a biomarker in gastric cancer tissues obtained from patients with locally advanced gastric cancer (GC) who underwent radical resection. PATIENTS AND METHODS: WARS1 expression in GC tissues and adjacent normal gastric mucosa of 253 patients with pStage II/III GC who underwent curative resection was determined using quantitative polymerase chain reaction (PCR). Association of WARS1 expression levels, categorized into high and low expression based on the median expression levels, with clinicopathological factors and overall survival (OS) of these patients was assessed. RESULTS: The low-WARS1 expression group had significantly higher serosal invasion, lymph node metastasis, lymphatic invasion, venous invasion, and pathological stage than did the high-WARS1 expression group. OS was significantly worse in the low- than in the high-WARS1 expression group (5-year survival 52.2% vs. 75.9%; p=0.0001). Furthermore, in multivariate analysis, low WARS1 expression was an independent predictor for poor OS (hazard ratio=2.101; 95% confidence interval=1.328-3.322; p=0.002). CONCLUSION: In patients with locally advanced GC, after curative resection, WARS1 expression in GC tissue may be a useful prognostic marker.

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.

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 C-reactive 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.

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.

BACKGROUND/AIM: Chitinase-3-like protein 1 (CHI3L1), encoded by CHI3L1, is thought to be involved in growth, invasion, migration, and resistance to chemotherapy in cancer. This study aimed to investigate the clinical significance of CHI3L1 expression as a biomarker in gastric cancer (GC) tissues of patients with locally advanced GC after curative resection. PATIENTS AND METHODS: Quantitative polymerase chain reaction (PCR) was used to determined CHI3L1 expression in GC tissues and adjacent normal gastric mucosa of 253 patients with pStage II/III GC who underwent curative resection. We compared the expression levels in GC tissues and adjacent normal gastric mucosa, and examined the relationship between expression in GC tissues and clinicopathological factors and overall survival (OS) in these patients. RESULTS: CHI3L1 expression was significantly associated with lymph-node metastasis and venous invasion. OS rate was significantly lower in the high- than in the low-CHI3L1 expression group (5-year survival 55.5% vs. 72.6%; p=0.009). Furthermore, in multivariate analysis, high CHI3L1 gene expression was an independent factor for poor OS (hazard ratio=2.030; 95% confidence interval=1.318-3.127; p=0.001). CONCLUSION: In patients with locally advanced GC after curative resection, expression of the CHI3L1 in GC tissue may be a useful prognostic marker.

BACKGROUND/AIM: Pregnancy zone protein (PZP), encoded by PZP, belongs to the α-2-macroglobulin superfamily, and plays an important role in inflammatory responses and immune cell activation in cancer. However, the relationship between gastric cancer (GC) and PZP is poorly studied. This study investigated the clinical significance of PZP expression in GC tissues of patients with locally advanced GC after curative resection. PATIENTS AND METHODS: Using quantitative polymerase chain reaction, we measured PZP expression in GC tissues and adjacent normal gastric mucosa of 253 patients with pStage II/III GC who underwent curative resection. We compared the expression levels of PZP in GC tissues and adjacent normal gastric mucosa and examined the relationship of PZP expression in GC tissues with clinicopathological factors and overall survival (OS). RESULTS: PZP expression was significantly associated with histology, venous invasion, and pathological stage. The high PZP expression group had significantly worse OS than did the low expression group (5-year survival 48.6% vs. 68.5%, p=0.0003). Furthermore, in multivariate analysis, high PZP expression was an independent factor for poor OS (hazard ratio=1.984, 95% confidence interval=1.307-3.012, p=0.0013). CONCLUSION: In post-curative resection patients with locally advanced GC, PZP expression in GC tissue may be a useful prognostic marker.

BACKGROUND/AIM: The asialoglycoprotein receptor 2 gene (ASGR2) encodes a subunit of the asialoglycoprotein receptor, a transmembrane protein, which has recently been reported to be involved in gastric cancer (GC) progression. This study aimed to investigate the clinical significance of ASGR2 expression in GC tissues of patients with locally advanced gastric cancer (LAGC) after curative resection. PATIENTS AND METHODS: ASGR2 expression was measured in GC tissues and adjacent normal gastric mucosa in 253 patients with pStage II/III GC who underwent curative resection, by using quantitative polymerase chain reaction. We compared the expression levels in GC tissues and adjacent normal stomach mucosa, and evaluated the relationship of its expression in GC tissues with clinicopathological factors and overall survival (OS). RESULTS: ASGR2 expression was significantly associated with lymph node metastasis and venous invasion. The high ASGR2-expression group demonstrated significantly lower survival than the low expression group (5-year survival 55.5% vs. 72.6%; p=0.009). Furthermore, in multivariate analysis, high ASGR2 expression was an independent factor for poor OS (hazard ratio=2.030; 95% confidence interval=1.318-3.127; p=0.001). CONCLUSION: ASGR2 expression in GC tissues may be a useful prognostic marker in patients with LAGC after curative resection.

BACKGROUND/AIM: Dietary intake (DI) loss after gastrectomy is a serious problem for patients with gastric cancer. This study compared the dietary intake after surgery in patients with early gastric cancer who received laparoscopic distal gastrectomy (LDG) versus those who underwent conventional open distal gastrectomy (ODG). PATIENTS AND METHODS: This was a prospective, observational study enrolling patients who underwent gastrectomy for gastric cancer. Dietary intake was assessed using the food frequency questionnaire with eighty-two food items (FFQW82) at nutritional counseling before surgery and one and three months after surgery. RESULTS: A total of 118 patients were included. Among them, 69 (58.5%) were male, and 49 (41.5%) were female. Seventy-five (63.6%) received LDG, and 43 (36.4%) received ODG. At 1 month postoperatively, the median DI in the LDG group was 1,540 (1,014-2,195) kcal/day, whereas that in the ODG group was 1547 (986-2,143) kcal/day (p=0.891). At 3 months postoperatively, the median DI in the LDG group was 1,624 (1,050-2,443) kcal/day, and that in the ODG group was 1,652 (917-2,144) kcal/day (p=0.749). There was no significant difference in the DI loss rate at 1 month (median: -8.2% vs. -9.3%, p=0.398) and 3 months (median: -3.2% vs. -3.7%, p=0.635) between the LDG and ODG groups. CONCLUSION: Minimally invasive laparoscopic surgery may not prevent postoperative DI loss after distal gastrectomy. Therefore, methods other than laparoscopic surgery are needed to prevent post-gastrectomy DI loss.

BACKGROUND/AIM: Based on gastric shape, patients with gastric cancer can be divided into storage (hook-shaped and ptotic stomach) and reverse outflow (steer-horn 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.

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.

BACKGROUND/AIM: Intraoperative blood loss (IBL) has been reported to decrease survival after surgical resection of some malignancies; however, there are few reports on the effects of IBL on recurrence and survival in locally advanced esophageal cancer. Therefore, we investigated the relationship between IBL and postoperative recurrence and overall survival in patients who underwent surgery for esophageal cancer. PATIENTS AND METHODS: One hundred and ninety-eight patients with locally advanced esophageal cancer who underwent preoperative adjuvant chemotherapy and curative resection as standard treatment were included in this study. Based on a defined cut-off value for IBL, 27 and 171 patients were classified into the high and low IBL groups, respectively. The relationship between each group and clinicopathological factors, postoperative recurrence, and overall survival were investigated. RESULTS: In terms of the relationship between IBL and clinicopathological factors, the high IBL group had significantly more patients with pathological T4, longer operative time, and higher incidence of postoperative complications than the low IBL group. Both recurrence-free and overall survival were significantly worse in the high IBL group than in the low IBL group. Furthermore, multivariate analysis identified high IBL as an independent factor for predicting poor reference free survival and overall survival. CONCLUSION: Heavy IBL in patients with locally advanced esophageal cancer may be a useful predictor of postoperative recurrence and overall survival.

BACKGROUND/AIM: The C-reactive protein to prealbumin ratio (CPAR) has been proposed and introduced in gastrointestinal cancer management. This study aimed to evaluate the clinical impact of the CPAR in patients with gastric cancer (GC) who received curative treatment. PATIENTS AND METHODS: This study included 447 patients who underwent curative treatment for GC between 2013 and 2017. The prognosis and clinicopathological parameters were compared between patients with high and low CPARs. RESULTS: Overall survival (OS) stratified by each clinical factor was compared using the log-rank test, and a significant difference was observed using a pretreatment CPAR of 5.0. Significant differences were observed in the 3- and 5-year OS rates of the CPAR-low (CPAR <5.0) and CPAR-high (CPAR ≥5.0) groups. The 3- and 5-year OS rates were 92.6% and 87.8%, respectively, in the CPAR-low group and 88.0% and 75.4% in the CPAR-high group. The CPAR was determined to be a significant prognostic factor for OS in a multivariate analysis (p=0.032). Similar results were observed for recurrence-free survival. CONCLUSION: The CAPR is a prognostic factor for GC patients. Therefore, the CAPR may be a promising nutritional biomarker of inflammation that can be applied in the management of GC patients.

BACKGROUND/AIM: We evaluated the clinical impact of the Geriatric Nutritional Risk Index (GNRI) in patients who received curative treatment and perioperative adjuvant treatment. We also investigated the association between the GNRI and the clinicopathological features of patients with GC. PATIENTS AND METHODS: This study included 280 patients who underwent curative treatment for GC between 2005 and 2020. The prognosis and clinicopathological parameters of the high-GNRI and low-GNRI groups were compared. RESULTS: In the GNRI-high group, the overall survival (OS) rates at 3 and 5 years after surgery were significantly lower (82.7% and 77.9%, respectively) than those in the GNRI-low group (56.4% and 40.8%). The GNRI was selected for the final multivariate analysis model for OS. The GNRI was also a significant prognostic factor for recurrence-free survival (RFS). The RFS rates at 3 and 5 years after surgery were 79.1% and 74.8%, respectively, in the GNRI-high group, and 48.0% and 38.6% in the GNRI-low group. The GNRI was selected for the final multivariate analysis model for RFS. The GNRI was also found to affect the postoperative clinical course, including postoperative surgical complications and postoperative adjuvant chemotherapy. CONCLUSION: The GNRI may be a promising prognostic and predictive factor for gastric cancer. In the future, the GNRI may be used to select optimal treatment strategies.
