A propensity‑matched analysis of the prognostic value of advanced lung cancer inflammation index in patients with gastric cancer after curative resection. Oncol Lett 2024; 27:285. [PMID: 38736744 PMCID: PMC11083996 DOI: 10.3892/ol.2024.14418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Accepted: 04/04/2024] [Indexed: 05/14/2024] Open
Abstract
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 Prognostic Immune and Nutritional Index in Gastric Cancer Patients Who Received Curative Treatment. Anticancer Res 2024; 44:2231-2238. [PMID: 38677750 DOI: 10.21873/anticanres.17030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 03/20/2024] [Accepted: 03/21/2024] [Indexed: 04/29/2024]
Abstract
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.

Abstract
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 CRP-albumin-lymphocyte (CALLY) Index Is an Independent Prognostic Factor for Gastric Cancer Patients who Receive Curative Treatment. Anticancer Res 2024; 44:1629-1636. [PMID: 38537973 DOI: 10.21873/anticanres.16961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 02/10/2024] [Accepted: 02/12/2024] [Indexed: 04/05/2024]
Abstract
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.

Abstract
BACKGROUND Recently, change in the C-reactive protein/albumin ratio (CAR) has become a promising prognostic marker in some malignancies. The aim of the present study was to evaluate the clinical impact of change in the CAR in gastric cancer patients who received curative resection. METHOD The present study included 458 patients who underwent curative treatment for gastric cancer between 2013 and 2017. The prognosis and clinicopathological parameters were compared between patients who showed a high-change in CAR and those who showed a low-change in CAR. RESULTS The OS stratified by each clinical factor was compared using a log-rank test, and a significant difference was observed using a 0.05 change in CAR. When the patient background factors were compared between the high-change (change in CAR ≥ 0.05) and low-change (change in CAR < 0.05) groups, the median age, sex ratio, T factor, and N factor were similar. In the low-change group, the OS rates at 3 and 5 years after surgery were 94.1% and 87.6%, respectively, which amounted to a significant difference from the low-change group, with rates of 83.6 and 77.5% in the high-change group. In the low-change group, the RFS rates at 3 and 5 years after surgery were 90.1% and 85.1%, respectively, while those in the high-change group 77.6 and 75.2%. The univariate and multivariate analyses of factors associated with OS and RFS showed that the change in CAR was a significant prognostic factor. CONCLUSIONS The change in CAR is a significant risk factor and promising prognostic factor for gastric cancer patients.

Abstract
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.

Abstract
AIM Recently, change in the neutrophil to lymphocyte ratio (cNLR) has been shown to be a promising prognostic inflammation marker in some malignancies. The aim of the present study was to evaluate the clinical impact of the cNLR in gastric cancer patients who received curative gastrectomy. PATIENTS AND METHODS The present study included 450 patients who underwent curative treatment for gastric cancer between 2013 and 2017 at Kanagawa Cancer Center. The cNLR was defined as follows: cNLR = NLR at 1 month after surgery-NLR at 1 week before surgery. The prognosis and clinicopathological parameters of the increased cNLR and decreased cNLR groups were analyzed. RESULTS The OS stratified by each clinical factor was compared using the log-rank test, and a significant difference was observed using a cutoff value of cNLR at 0.762. When comparing the patient background factors between the increased cNLR (≥ 0.762) and decreased cNLR (< 0.762) groups, there were no significant differences in age, sex, T status, or N status. In the increased cNLR group, the OS rates at 3 and 5 years after surgery were 87.5% and 77.3%, respectively, while those in the decreased cNLR group were 92.8% and 87.3%, which amounted to a statistically significant difference (p = 0.041). The univariate and multivariate analyses of factors associated with OS showed that cNLR was a significant prognostic factor. When the postoperative course was compared between the two groups, the incidence rates of postoperative surgical complications and other-cause death were significantly higher in the increased cNLR group (p = 0.001 and p = 0.005, respectively). CONCLUSION The cNLR is one of the significant risk factors in gastric cancer patients. Our results suggested that the changes of inflammation status during perioperative periods might be a promising prognostic factor for gastrointestinal cancer patients.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND/AIM Perioperative inflammation and the nutritional status affect both short- and long-term oncological outcomes in various malignancies. We clarified the clinical impacts of the CRP-albumin-lymphocyte (CALLY) index in patients with esophageal cancer who received curative treatment. PATIENTS AND METHODS The present study included 180 patients who underwent curative treatment for esophageal cancer between 2005 and 2020. The prognosis and clinicopathological parameters were compared between a high-fibrinogen group and a low-fibrinogen group. RESULTS The 3- and 5-year overall survival rates were 50.0% and 42.6%, respectively, in the CALLY index-low group, and 75.9% and 66.6% in the CALLY index-high group. The differences between the two groups were statistically significant (p<0.001). Univariate and multivariate analyses demonstrated that the CALLY index was an independent prognostic factor [hazard ratio=2.310, 95% confidence interval=1.416-3.767, p<0.001]. Similar results were observed in recurrence-free survival. When comparing the details of postoperative surgical complications, there was a significant difference in the incidence of anastomotic leakage. The incidence of anastomotic leakage was 40.2% in the CALLY index-low group, while it was 27.5% in the CALLY index-high group (p=0.030). CONCLUSION The pretreatment CALLY index is one of the independent prognostic factors for esophageal cancer. The CALLY index might become a promising biomarker for the treatment and management of esophageal cancer.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND/AIM Pretreatment fibrinogen levels are a promising prognostic marker for some malignancies. The aim of the present study was to evaluate the clinical impact of fibrinogen levels before treatment in patients with esophageal cancer who underwent curative resection. PATIENTS AND METHODS This study included 123 patients who underwent curative treatment for esophageal cancer between 2005 and 2020. The prognosis and clinicopathological parameters in the high fibrinogen and low fibrinogen groups were analyzed. RESULTS Overall survival (OS) stratified by individual clinical factors was compared using the log-rank test, and a significant difference was observed when a pretreatment fibrinogen level of 400 g/dl was used as a cutoff value. The comparison of the patient background factors between the high fibrinogen (400 g/dl) and low fibrinogen (<400 g/dl) groups revealed significant differences in pathological T status and lymph node metastasis. In the low fibrinogen group, the OS rates at 3 and 5 years after surgery (71.4% and 58.1%, respectively) were significantly higher than those in the high fibrinogen group (38.3% and 32.4%, respectively). Univariate and multivariate analyses for OS showed that the fibrinogen level prior to treatment was a significant prognostic factor. Similar results were observed for recurrence-free survival. In addition, when the first recurrence site was compared, there were marginally significant differences in hematologic recurrence. CONCLUSION Pretreatment fibrinogen levels are a significant risk factor in patients with esophageal cancer. Therefore, pretreatment fibrinogen levels are a promising prognostic factor for patients with esophageal cancer.

Significance of Preoperative Modified Nutritional Risk Index in Patients With Gastric Cancer After Curative Resection. In Vivo 2024; 38:264-271. [PMID: 38148088 PMCID: PMC10756440 DOI: 10.21873/invivo.13434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 09/21/2023] [Accepted: 09/25/2023] [Indexed: 12/28/2023]
Abstract
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.

Asialoglycoprotein Receptor 2 Expression in Patients With Locally Advanced Gastric Cancer After Curative Resection. Anticancer Res 2024; 44:397-402. [PMID: 38159992 DOI: 10.21873/anticanres.16824] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 11/21/2023] [Accepted: 11/22/2023] [Indexed: 01/03/2024]
Abstract
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.

Clinical Significance of Chitinase-3-like Protein 1 Gene Expression in Patients With Locally Advanced Gastric Cancer. Anticancer Res 2024; 44:307-312. [PMID: 38159969 DOI: 10.21873/anticanres.16813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 11/23/2023] [Accepted: 11/24/2023] [Indexed: 01/03/2024]
Abstract
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.

Effect of Preoperative Gastric Shape on Loss of Lean Body Mass After Distal Gastrectomy. In Vivo 2024; 38:445-452. [PMID: 38148040 PMCID: PMC10756446 DOI: 10.21873/invivo.13458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 09/07/2023] [Accepted: 09/14/2023] [Indexed: 12/28/2023]
Abstract
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.

Abstract
BACKGROUND/AIM The perioperative nutritional status has recently been reported to influence the prognosis of various types of cancer. We investigated the relationship between the Geriatric Nutritional Risk Index (GNRI) and overall survival (OS) and recurrence-free survival (RFS) in patients with esophageal cancer who received radical and adjuvant therapy. PATIENTS AND METHODS Patients who underwent radical resection for esophageal cancer at our hospital (n=187) were included. Background characteristics, surgical factors, and OS were examined retrospectively. The GNRI was calculated using preoperative values, with GNRI <98 classified as low-GNRI. RESULTS Seventy-five and 112 patients were classified into the GNRI-low and -high groups, respectively. The 3- and 5-year OS rates were 75.7% and 66.7%, respectively, in the GNRI-high group and 43.2% and 36.7% in the GNRI-low group; the difference was statistically significant (p<0.001). In the univariate and multivariate analyses, low-GNRI was selected as a risk factor for OS. The hazard ratio for low-GNRI was 2.184 (95% confidence interval=1.361-3.508, p=0.001). The 5-year RFS rate in the high- and low-GNRI groups was 54.6% and 25.0%, respectively (p=0.001). In the univariate and multivariate analyses, low-GNRI was a risk factor for RFS. The hazard ratio for low-GNRI was 1.704 (95%CI=1.121-2.590, p=0.013). Regarding the type of recurrence, lymph node recurrence was significantly more common in the low-GNRI group (p=0.008). CONCLUSION Low-GNRI was an independent risk factor for OS and RFS after radical resection of esophageal cancer. The preoperative GNRI may be a useful prognostic factor after esophageal cancer surgery.

Abstract
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.

Abstract
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
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.

Abstract
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
Abstract
Background
Magnification endoscopy and magnification narrow-band imaging are image enhanced endoscopy technologies that may allow for the diagnosis of advanced neoplasia in the GI tract on the basis of imaging characteristics. Recently, the Unified Magnifying Endoscopic Classification (UMEC) has been developed, which unified the criteria for the esophagus, stomach, and colon. UMEC divides optical diagnosis into one of the three categories: non-neoplastic, intramucosal neoplasia, and deep submucosal invasive cancer.
Purpose
The objective of this study is to educate North American endoscopists on the use of the UMEC schema, and to ascertain performance of the UMEC framework among North American endoscopists.
Method
Using UMEC, five North American endoscopists (>1000 procedures) without prior training in magnifying endoscopy independently diagnosed previously collected endoscopic image set of the esophagus, stomach, and colon. The endoscopists were trained on the use of UMEC via an eleven-minute training video with exemplars of each element of UMEC from esophagus, stomach, and colon. All endoscopists were blinded to white-light and non-magnifying NBI findings as well as histopathological diagnosis. The diagnostic performance of UMEC was assessed while using the gold standard histopathology as a reference.
Result(s)
A total of 299 gastrointestinal lesions (77 esophagus, 92 stomach, and 130 colon) were assessed using UMEC. For esophageal squamous cell carcinoma, the sensitivity, specificity, and accuracy for all 5 endoscopists ranged from 65.2% (95% CI: 50.9–77.9) to 87.0% (95% CI: 75.3–94.6), 77.4% (95% CI: 60.9–89.6) to 96.8% (95% CI: 86.8–99.8), and 75.3% to 87.0%, respectively. For gastric adenocarcinoma, the sensitivity, specificity, and accuracy for all 5 endoscopists ranged from 94.9% (95% CI: 85.0–99.1) to 100%, 52.9% (95% CI: 39.4–66.2) to 92.2% (95% CI: 82.7–97.5), and 73.3% to 93.3%, respectively. For colorectal adenocarcinoma, the sensitivity, specificity, and accuracy for all 5 endoscopists ranged from 76.2% (95% CI: 62.0–87.3) to 83.3% (95% CI: 70.3–92.5), 89.7% (95% CI: 82.1–94.9) to 97.7% (95% CI: 93.1–99.6), and 86.8% to 90.7%, respectively.

Conclusion(s)
UMEC is a simple and practical classification that can be used to introduce and educate endoscopists to magnification narrow-band imaging and optical diagnosis.

Abstract
Abstract
Background
Delayed door-to-balloon (DTB) time and deterioration of in-hospital mortality during the coronavirus disease 2019 (COVID-19) pandemic have been reported. Little is known about the impact of changes in in-hospital medical management before primary percutaneous coronary intervention (PCI) for COVID-19 such as screening test (antigen or polymerase chain reaction (PCR) tests, chest CT for excluding the pneumoniae) and primary PCI under full personal protective equipment (PPE) on DTB time and in-hospital mortality.
Purpose
The purpose of this study was to evaluate the impact of in-hospital medical management for COVID-19 on DTB time and in-hospital mortality during COVID-19 pandemic period.
Methods
We compared DTB time and in-hospital mortality of 502 ST-elevation myocardial infarction (STEMI) patients during COVID-19 pandemic (February 2020 and January 2021) with 2035 STEMI patients before pandemic (February 2016 and January 2020) using date from Mie ACS registry, a retrospective and multicenter registry.
Results
The COVID-19 screening tests before primary PCI and/or primary PCI under full PPE was performed on 173/502 (34.5%) patients (antigen or PCR tests; 39 (7.8%), chest CT; 156 (31.3%), full PPE; 11 (2.2%)). These patients had lower rate of achievement of DTB time ≤90 min compared with others (Figure 1A). Moreover, In-hospital management of COVID-19 screening tests and/or primary PCI under full PPE was an independent factor of DTB time>90 min with odds ratio of 1.94 (95% confidential interval: 1.37–2.76, p<0.001). In addition, in-hospital mortality of those patients was higher compared with others (Figure 1B).
Conclusion
In-hospital medical management for COVID-19 screening tests before primary PCI and/or primary PCI under full PPE was the independent factor of DTB time>90 min. This study reinforces the need to focus efforts on shortening DTB time, while controlling the epidemic of infection.

Abstract
An 83-year-old woman visited our emergency department with a chief complaint of abdominal pain and vomiting. Abdominal computed tomography showed thickening of the wall of the small intestine in the right middle abdomen and marked bowel dilation and fluid retention in the oral side of the small intestine. The patient was diagnosed with adhesive bowel obstruction and hospitalized for conservative treatment. However, the treatment was unsuccessful, and laparoscopic surgery was performed. The intraoperative findings included thickening of the wall and hardening of the obstructed part, suggestive of an intestinal tumor; thus, this part was resected. A histopathological examination revealed diffuse infiltration of large-sized atypical lymphocytes in the tumor, and diffuse large B-cell lymphoma was diagnosed through immunochemical staining. The postoperative course was uneventful, and the lymphoma has not recurred. Intestinal malignant lymphoma rarely causes bowel obstruction without invagination. Here, we report this case and review the literature.

Abstract
A 77-year-old man with a medical history of hypertension, dyslipidemia, angina pectoris, and internal carotid artery stenosis underwent laparoscopy-assisted distal gastrectomy, D2 lymphadenectomy, and Billroth Ⅰ reconstruction for advanced gastric cancer. Hematologic examination revealed severe anemia on postoperative day 2, and abdominal CT scan detected contrast media leakage into the remnant gastric lumen. Upper gastrointestinal endoscopy revealed mucosal necrosis and ulceration of a large range. The patient recovered with conservative treatment and was discharged on postoperative day 18. Endoscopic balloon dilation was required to improve anastomotic stenosis after discharge, after which the patient received adjuvant chemotherapy. The stomach is resistant to ischemic changes because of the microvascular networks in the stomach wall; thus, gastric remnant necrosis after gastrectomy is rare. However, for patients with arterial sclerosis, such as in this case, physicians must consider the range of gastrectomy and reconstruction methods.

Abstract
BACKGROUND Although patients with schizophrenia have a higher risk of developing breast cancer than the general population, studies that have investigated postoperative complications after breast cancer surgery in patients with schizophrenia are scarce. This study examined associations between schizophrenia and short-term outcomes following breast cancer surgery. METHODS Patients who underwent surgery for stage 0-III breast cancer between July 2010 and March 2017 were identified from a Japanese nationwide inpatient database. Multivariable analyses were conducted to compare postoperative complications and hospitalization costs between patients with schizophrenia and those without any psychiatric disorder. Three sensitivity analyses were performed: a 1 : 4 matched-pair cohort analysis with matching for age, institution, and fiscal year at admission; analyses excluding patients with schizophrenia who were not taking antipsychotic medication; and analyses excluding patients with schizophrenia who were admitted to hospital involuntarily. RESULTS The study included 3660 patients with schizophrenia and 350 860 without any psychiatric disorder. Patients with schizophrenia had a higher in-hospital morbidity (odds ratio (OR) 1.37, 95 per cent c.i. 1.21 to 1.55), with more postoperative bleeding (OR 1.34, 1.05 to 1.71) surgical-site infections (OR 1.22, 1.04 to 1.43), and sepsis (OR 1.20, 1.03 to 1.41). The total cost of hospitalization (coefficient €743, 95 per cent c.i. 680 to 806) was higher than that for patients without any psychiatric disorder. All sensitivity analyses showed similar results to the main analyses. CONCLUSION Although causal inferences remain premature, multivariable regression analyses showed that schizophrenia was associated with greater in-hospital morbidity and higher total cost of hospitalization after breast cancer surgery than in the general population.

Abstract
The patient was a 59‒year‒old woman. In 2005, she underwent low anterior resection plus D2 dissection for rectal cancer (pT4aN2aM0, pStage Ⅲb). In 2007, she underwent hepatic S8 subsegment resection for liver metastasis. After that, FOLFIRI therapy was performed as chemotherapy for recurrence of the right upper lung lobe and para‒aortic lymph node(PALN). CR was once obtained in both(of)PALN and lung, but PALN re‒expansion and left ovary enlargement were observed in 2009, and resection of PALN plus left ovariectomy was performed. Histological examination showed PALNs were metastases from rectal cancer and the ovary was benign. Eleven years after the first operation, she stayed alive without recurrence.

Abstract
A 63-year-old-woman was diagnosed with gastric cancer cStage ⅠA after ESD, and then, underwent robot-assisted distal gastrectomy. She vomited on the postoperative day 2 and then was inserted nasogastric tube. The amount of drainage from the tube was increased on the postoperative day 5, therefore, abdominal computed tomography scan was performed, which showed herniation of small bowel at the 8 mm port site in the left upper abdomen. The emergent surgery was performed because of difficulty in manual reduction. Intraoperative findings showed that small intestine was incarcerated at the left 8 mm port-site. The intestine was released by incising the fascia of hernia orifice, then, the fascia was repaired. There was no recurrence of gastric cancer and port-site hernia for 34 months after surgery. In general, the fascia of over 10 mm port site is sutured and closed to avoid port-site hernia, however, it is unclear whether the fascia of 8 mm port-site should be closed after robotic surgery. Since we experienced this case, we have also performed fascia suture on the 8 mm port-site in all cases. And then, we could prevent occurrence of port-site hernia in the 8 mm port-site.

Abstract
A case of 69-year-old man underwent resection for the plantar surface of left foot malignant melanoma and received a sentinel biopsy of left inguinal lymph node. Two years and 10 months later, a mass of 30 mm in diameter in the ileum was detected by contrast-enhanced computed tomography, which showed abnormal uptake using FDG positron emission tomography. The partial intestinal resection was performed, and then, the mass was diagnosed as metastasis of malignant melanoma by pathological examination. Malignant melanoma is highly malignant disease that frequently shows distant metastasis. Although the malignant melanoma with distant metastasis shows poor prognosis, previous studies reported the prognosis could be improved when the patient could receive curative resection for single intraabdominal metastasis. Therefore, surgical resection should be considered for the single metastasis of malignant melanoma. We report a case of malignant melanoma with ileum metastasis resected curatively with literature review.

Abstract
BACKGROUND In the absence of randomized controlled data and even propensity-matched data, indications for, and outcomes of, laparoscopic repeat liver resection for hepatocellular carcinoma (HCC) remain uncertain. This study aimed to clarify the current indications for laparoscopic repeat liver resection for HCC, and to evaluate outcomes. METHODS Forty-two liver surgery centres around the world registered patients who underwent repeat liver resection for HCC. Patient characteristics, preoperative liver function, tumour characteristics, surgical method, and short- and long-term outcomes were recorded. RESULTS Analyses showed that the laparoscopic procedure was generally used in patients with relatively poor performance status and liver function, but favourable tumour characteristics. Intraoperative blood loss (mean(s.d.) 254(551) versus 748(1128) ml; P < 0·001), duration of operation (248(156) versus 285(167) min; P < 0·001), morbidity (12·7 versus 18·1 per cent; P = 0·006) and duration of postoperative hospital stay (10·1(14·3) versus 11·8(11·8) days; P = 0·013) were significantly reduced for laparoscopic compared with open procedures, whereas survival time was comparable (median 10·04 versus 8·94 years; P = 0·297). Propensity score matching showed that laparoscopic repeat liver resection for HCC resulted in less intraoperative blood loss (268(730) versus 497(784) ml; P = 0·001) and a longer operation time (272(187) versus 232(129); P = 0·007) than the open approach, and similar survival time (12·55 versus 8·94 years; P = 0·086). CONCLUSION Laparoscopic repeat liver resection is feasible in selected patients with recurrent HCC.

Abstract
A 52-year-old man whose fecal occult blood test was positive was found to have type 2 sigmoid colon cancer by colonoscopy. On enhanced barium enema study, the cecum was in the pelvis, and the ascending colon was running medially in the abdomen. Enhanced CT scan of the abdomen revealed rotation of the superior mesenteric vein(SMV). We diagnosed the case as sigmoid colon cancer(cT3N0M0, StageⅡA)with non rotation-type intestinal malrotation, and performed laparoscopic surgery. We confirmed the small intestine to be located on the right side of the abdomen, the cecum to be located in the pelvis, and the ascending colon to be running medially in the abdomen. The ascending mesocolon was adherent to the right of the sigmoid mesocolon. Following dissections of the ascending mesocolon from the sigmoid mesocolon, we performed surgery via the inside approach as usual. We dissected the root of the inferior mesenteric artery(IMA), and the operation was completed. In laparoscopic surgery for colorectal cancer with intestinal malrotation, there are some reports that it could be performed safely if attention is paid to adhesion of the mesenteries and vascular variation in the course of preoperative imaging diagnosis. We report a case of laparoscopic surgery that could be safely performed for sigmoid colon cancer with non rotation-type intestinal malrotation.

Impact of Portal Hemodynamic Changes in Partial Liver Grafts on Short-Term Graft Regeneration in Living Donor Liver Transplantation. Transplant Proc 2017; 48:2747-2755.

Abstract
BACKGROUND Regeneration of partial liver grafts is critical for successful living donor liver transplantation (LDLT), especially in adult recipients. The purpose of this study was to investigate the intraoperative hemodynamic changes in partial liver grafts and characterize their potential impact on post-transplant liver regeneration in LDLT. METHODS We examined the portal venous flow (PVF) and hepatic arterial flow (HAF) to partial liver grafts by means of ultrasonic transit time flowmeter of donors immediately before graft retrieval and of the corresponding recipients after vascular reconstruction in 48 LDLT cases. We evaluated post-transplant liver regeneration according to the changes in graft liver volume between the time of transplantation and the 7th post-transplant day. RESULTS There was a significant increase in PVF to the partial liver grafts in recipients (rPVF) compared with that in donors. In contrast, graft HAF in recipients significantly decreased compared with that in donors. The rPVF inversely correlated with graft weight (GW)-recipient body weight ratio (GRWR), whereas HAF volume showed no significant correlation. The rPVF/GW positively correlated with the rate of liver regeneration (GRR), which inversely correlated with GRWR. The rPVF/GW was significantly higher, and GRR tended to be larger in the small graft group than in the non-small graft group. CONCLUSIONS Intraoperative portal hemodynamic changes in partial liver grafts strongly affect their post-transplant regeneration. In particular, in small liver grafts, an immediate and remarkable increase in graft PVF may contribute to rapid liver regeneration after LDLT if the increased PVF remains within a safe range.

Abstract
A novel method is presented for evaluation of the absolute optical responsivity of a photomultiplier tube (PMT) at optical powers down to the photon counting level under visible light. This method is based on a combination of the calibrated responsivity and nonlinearity corrections using a silicon photodiode and a PMT. The evaluation results with the PMT enable accurate determination of the absolute optical responsivity over a wide power range of 10-11 W to 10-16 W under visible light. This method provides validation of both the photon counting efficiency of a PMT and of accurate optical measurement with attenuators at the photon counting level.

Abstract
Abstract
Purpose: This study aimed to evaluate response to neoadjuvant chemotherapy (NAC) for patients with hormone receptor-negative (HR-negative) breast cancer (BC) to identify subtypes that require anthracycline treatment.
Methods: In total, 103 patients with operable HR-negative BC were registered. They were randomely assigned to administration of 6 cycles of docetaxel (75mg/m2) and cyclophosphamide (600 mg/m2) (TC6) or 3 cycles of 5-fluorouracil (500 mg/m2), epirubicin (100mg/m2), and cyclophosphamide (500mg/m2) followed by 3 cycles of docetaxel (100mg/m2) (FEC-D). Cytokeratin (CK) 5/6 and EGFR expression were used to identify basal and non-basal triple-negative (TN) BC. The primary endpoint was pathological complete response (pCR); secondary endpoints were safety, breast-conserving surgery, disease-free survival, and overall survival. Predictive factors of pCR for each regimen were also evaluated.
Results:
The pCR rate was 36% for FEC-D and 25.5% for TC6, which did not differ significantly (P=0.265). When TN BC was subdivided into basal and non-basal subtypes, the pCR rate in the basal subtype was significantly lower for TC6 (13.6%) than for FEC-D (42.9%) (P=0.033), but did not significantly differ in the non-basal (TC6, 36.4%; FEC-D, 25.0%) and HER2-positive (TC6, 41.7%; FEC-D, 35.7%) cases.
The relative dose intensities of epirubicin and docetaxel in FEC-D and docetaxel in TC6 were 96.3±13.0%, 93.5±14.6%, and 93.9±16.3% (mean±SD), respectively. Occurrence of grade ≥2 adverse events was significant in FEC-D-treated patients. Poor appetite (P<0.001), nausea (P<0.001), vomiting (P<0.001), dysgeusia (P=0.03), and fatigue (P=0.05) were significantly more common for FEC-D than TC6. Patients treated with FEC-D experienced significantly more febrile neutropenia and anemia (P=0.016 and 0.017, respectively).
The rates of breast-conserving surgery were 68.0 and 72.3% for FEC-D and TC6, respectively (P=0.641).
Patients achieved pCR had better DFS (log rank test, P = 0.287) and OS (log rank test, P = 0.069), though not significant. Patients treated with FEC-D had better DFS (log rank test, P = 0.107) and OS (log rank test, P = 0.159), though not significant. Among patients with TN BC, those treated with FEC-D had significantly better DFS (log rank test, P = 0.016) and OS (log rank test, P = 0.034) than treated with TC6.
Low ALDH1 expression and high topo IIα protein expression were strongly correlated with pCR in FEC-D, with odds ratios (ORs) of 4.33 [95% CI, 1.02–18.38] and 4.08 [0.97–17.2], respectively. ALDH1 was also associated with pCR in TC, OR=3.50 [0.84–14.6]. Other factors, including age, tumor size, nodal status, tumor grade, Ki67, p53, and TOP 2A status were not associated with pCR in either regimen.
Conclusions:We found that TC6 was less effective than FEC-D for treating HR-negative BC because it was insufficient for TNBC, particularly for basal BC. This suggests that anthracycline is more important than taxane for basal BC. Additionally, ALDH1 could be a marker for resistance to conventional chemotherapy.

Abstract
OBJECTIVES More than two decades have passed since the first living donor liver transplantation was performed in Japan in 1989. There are many reports about problems in adherence to taking medication and medical follow-ups in children who received liver transplants, because there is no transition strategy for those children and parents or guardians. The objective of this study is to measure the effect of nature and outdoor activity to improve children's medical adherence. METHODS We recruited participants from 9-year-old children who are attending the outpatient liver transplant clinic in a stable condition (no event such as rejection or surgical procedure within 6 months). We took participants to a snow camp and measured its effect by using the IKIRU CHIKARA (IKR) tool, which contain 28 items divided into 3 categories: psychosocial ability, moral fitness, and physical ability. Children were tested on three occasions, before, just after, and 1 month after the camp. RESULTS Eight patients participated in the snow camp and 7 patients were eligible for the study. The average age was 12.6 with a range 10 to 17 years. There were 3 girls and 4 boys. The average IKR scores before, just after, and 1 month after the camp were 127.9, 131.5, and 126.6, respectively. CONCLUSION An outdoor activity such as a snow camp can be safely conducted, and it is an acceptable option to incorporate within a pediatric liver transplant program. There were no significant changes in IKR scores during this short observation. Longer observation is needed to measure the effect of nature and outdoor activities.

Abstract
PURPOSE Metabolic syndrome (MetS) is now well known as one of the major risk factors for coronary heart disease (CHD). Currently, there are several methods used to define MetS. The aim of this study was to determine to what extent current MetS definition reflects CHD risk using the probability of CHD in 10 years based on Framingham risk score algorithms. METHODS A total of 7575 adults, aged 16-93 years (2532 men and 5043 women), were recruited. We conducted a cross-sectional health survey in China using MetS criteria from four different definitions: modified National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III), International Diabetes Federation (IDF), Chinese and Japanese. RESULTS Differences in the prevalence of MetS by each definition were small in males (22.9-25.9 %), whereas in females, MetS was three times more prevalent using the IDF definition (29.1 %) versus the Japanese definition (9.7 %). Framingham risk scores in participants with MetS were significantly higher than in those without MetS by all definition criteria (p < 0.001). The CHD risk scores for participants with MetS by each definition showed similar values in males (range 11.5-12.1 %) with no significant differences among definitions. Conversely, in females with MetS the risk score for CHD was low (range 3.5-4.3 %) by each MetS definition. CONCLUSIONS These findings suggest that further studies are required to establish appropriate criteria of MetS in females.

Abstract
OBJECTIVE To provide information on trends on official development assistance (ODA) disbursement patterns for reproductive health activities in 18 conflict-affected countries. DESIGN Secondary data analysis. SAMPLE 18 conflict-affected countries and 36 non-conflict-affected countries. METHODS The Creditor Reporting System (CRS) database was analyzed for ODA disbursement for direct and indirect reproductive health activities to 18 conflict-affected countries (2002-2011). A comparative analysis was also made with 36 non-conflict-affected counties in the same 'least-developed' income category. Multivariate regression analyses examined associations between conflict status and reproductive health ODA and between reproductive needs and ODA disbursements. MAIN OUTCOME MEASURES Patterns of ODA disbursements (constant U.S. dollars) for reproductive health activities. RESULTS The average annual ODA disbursed for reproductive health to 18 conflict-affected countries from 2002 to 2011 was US$ 1.93 per person per year. There was an increase of 298% in ODA for reproductive health activities to the conflict-affected countries between 2002 and 2011; 56% of this increase was due to increases in HIV/AIDS funding. The average annual per capita reproductive health ODA disbursed to least-developed non-conflict-affected countries was 57% higher than to least-developed conflict-affected countries. Regression analyses confirmed disparities in ODA to and between conflict-affected countries. CONCLUSIONS Despite increases in ODA for reproductive health for conflict-affected countries (albeit largely for HIV/AIDS activities), considerable disparities remains. TWEETABLE ABSTRACT Study tracking 10 years of aid for reproductive aid shows major disparities for conflict-affected countries.

Abstract
Parasitic granulomatous eosinophilic inflammation was observed in the central nervous system (CNS) of a 6-month-old Arabian colt from New York state. Inflammation was associated with eggs, larvae, and adult nematodes in the cerebellum. Nematodes had histological characteristics of the superfamily Metastrongyloidea. The presence of dorsal-spined larvae in the CNS was further indicative of infection with a nematode in the family Protostrongylidae. Infections were most compatible with Parelaphostrongylus tenuis but specific diagnosis was not possible. This is the first definitive report of a protostrongylid nematode infection in a horse.

Abstract
INTRODUCTION Breast-conserving surgery is a standard treatment for early breast cancer. For ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery, salvage mastectomy is the current standard surgical procedure. However, it is not rare for patients with IBTR who have received salvage mastectomy to develop local recurrence. In this study, we examined the risk factors of local recurrence after salvage mastectomy for IBTR. PATIENTS AND METHODS A total of 118 consecutive patients who had histologically confirmed IBTR without distant metastases and underwent salvage mastectomy without irradiation for IBTR between 1989 and 2008 were included from eight institutions in Japan. The risk factors of local recurrence were assessed. RESULTS The median follow-up period from salvage mastectomy for IBTR was 4.6 years. Patients with pN2 or higher on diagnosis of the primary tumor showed significantly poorer local recurrence-free survival than those with pN0 or pN1 at primary tumor (p < 0.001). Multivariate analysis showed that the lymph node status of the primary tumor was a significantly independent predictive factor of local recurrence-free survival (p = 0.02). CONCLUSION The lymph node status of the primary tumor might be a predictive factor of local recurrence-free survival after salvage mastectomy for IBTR. Further research and validation studies are needed. (UMIN-CTR number UMIN000008136).

Abstract
AIM Triple negative breast cancer (TNBC) is a heterogeneous disease and is associated with the cancer stem cell (CSC), basal-like, and BRCA1 function deficient (BRCAness) subtypes. We examined these 3 subtypes in TNBC and compared their chemosensitivity against anthracycline or taxane with a special attention to BRCAness. METHODS Sixty-six TNBC cases were obtained from a randomized phase II trial comparing TCx6 (TC6) with FEC-Docetaxel (FEC-D) as neoadjuvant chemotherapy. The core needle specimens before chemotherapy were used for subtyping. The basal-like and CSC subtypes were identified by immunohistochemistry; CK5/6 and EGFR staining for the basal-like subtype and ALDH1 staining for the CSC subtype. The BRCAness subtype was examined by Multiplex Ligation-dependent Probe Amplification (MLPA). Correlations between subgroups and pCR rates according to each regimen and subtype were examined. RESULTS The basal-like and BRCAness subtypes were significantly associated (p = 0.010) with the other subtypes, but not the CSC subtype. The pCR rates were higher with FEC-D than with TC6 in the basal-like (54.5% vs 14.3%, p = 0.081) and BRCAness (56.2% vs 16.7%, p = 0.030) subtypes. Both were not effective in the CSC subtype (18.2% vs 11.8%, p = 1.00). CONCLUSION BRCAness identified by MLPA was practically useful for treatment selection for avoiding taxane. ALDH1 may be considered as a marker for the CSC subtype requiring novel agents.

[PMID: 25704556 DOI: 10.1016/j.ejso.2015.01.031] [Citation(s) in RCA: 77] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2014] [Revised: 01/20/2015] [Accepted: 01/23/2015] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND We compared clinical outcomes of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) against those of classical 2-stage hepatectomy in treating metastatic liver disease. METHODS Short-term outcomes, serial changes in volume of the future liver remnant (FLR), functional FLR volume, and tumor growth activity during the treatment period, were compared between our first 11 consecutive patients treated with ALPPS and 54 patients treated with classical 2-stage hepatectomy. RESULTS Mortality in the ALPPS group (9%) tended to be higher than in the classical 2-stage group (2%, P = 0.341). The FLR hypertrophy ratio (FLR volume after vs. before the procedure) 1 week after the first operation in the ALPPS group (1.54 ± 0.18) exceeded that in the classical 2-stage group (1.19 ± 0.29, P = 0.005), being similar to the ratio at 3 weeks after the first procedure in the classical 2-stage group (1.40 ± 0.43). However, functional volume of the FLR in the ALPPS group 1 week after the first procedure (52.1%) tended to be smaller than that in the classical group 3 weeks after the first procedure (59.2%). CONCLUSIONS ALPPS should be used with extreme caution, giving special attention to postoperative complications and grade of functional liver regeneration.

Change in estrogen receptor, HER2, and Ki-67 status between primary breast cancer and ipsilateral breast cancer tumor recurrence. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2015; 41:548-52. [PMID: 25682910 DOI: 10.1016/j.ejso.2015.01.030] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2014] [Revised: 01/07/2015] [Accepted: 01/19/2015] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Changes in the biological marker status between primary and recurrent tumors are observed in breast cancer. However, their clinical significance is still uncertain, especially for patients with ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery. PATIENTS AND METHODS A total of 117 patients with IBTR without distant metastases were enrolled in this study. All patients were examined for estrogen receptor (ER), HER2, and Ki-67 in both the primary tumors and paired IBTR. We evaluated the impact of changes in these biomarkers between primary tumors and IBTR on the prognosis after IBTR. RESULTS There were no associations of changes in the ER, HER2 status with distant disease-free survival (DDFS) after surgical resection of IBTR, whereas the change in the Ki-67 status between the primary tumors and IBTR was significantly correlated with DDFS (unadjusted: p = 0.0094; adjusted: p = 0.013). Patients in the "increased or remained high" Ki-67 group had a significantly shorter DDFS than those in the "decreased or remained low" Ki-67 group (5-year DDFS: 55.5 vs. 79.3%, respectively, p = 0.0084 by log-rank test). CONCLUSION An increased or persistently high Ki-67 status in the IBTR was significantly correlated with a poorer prognosis after IBTR.

A prospective feasibility study of sentinel node biopsy by modified Indigocarmine blue dye methods after neoadjuvant chemotherapy for breast cancer. Eur J Surg Oncol 2015; 41:566-70. [PMID: 25650249 DOI: 10.1016/j.ejso.2014.10.066] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2014] [Revised: 10/08/2014] [Accepted: 10/17/2014] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Although sentinel lymph node biopsy (SLNB) is a standard staging method for assessing nodal status of breast cancer patients, SLNB after neoadjuvant chemotherapy (NAC) remains controversial. The aim of this study was to validate the practicality and accuracy of SLNB by our modified Indigocarmine blue dye methods following NAC. METHODS One hundred consecutive cases with breast cancers treated by NAC were enrolled in this study. After NAC, all patients underwent SLNB performed by our modified Indigocarmine blue dye methods without radioisotope, followed by back-up axillary lymph node dissection (ALND). RESULTS Sentinel nodes (SNs) were identified in 94 cases (identification rate, 94%); the accuracy was 94.7% (89/94 cases); and the false negative rate (FNR) 13.5% (5/37 cases). For cases with vs. without clinically evident metastatic nodes before NAC, the identification rate was 92.4% (61/66 cases) vs. 97.1% (33/34 cases); the accuracy 91.8% (56/61 cases) vs. 97.0% (32/33 cases) and the FNR 16.1% (5/31 cases) vs. 0% (0/6 case), respectively. There were six patients without identified SNs, three of them had metastatic nodes. False negatives occurred in five cases; in four, fewer than two sentinel nodes had been removed. CONCLUSION Following NAC, the accuracy of SLNB by modified Indigocarmine blue dye methods is adequate compared with other tracers. In patients in whom no SNs have been identified, lymphatic metastasis is likely and therefore ALND is recommended. For patients with cN0 prior to NAC, SLNB by modified Indigocarmine blue dye methods is clinically feasible, though controversial for patients with positive nodes.
