RESUMO
PURPOSE: We investigated true indication of neoadjuvant therapy (NAT) in resectable pancreatic cancer and the optimal surgical timing in borderline resectable pancreatic cancer. METHODS: A total of 687 patients with resectable or borderline resectable pancreatic cancer were enrolled. Survival analysis was performed by intention-to-treat analysis and propensity score matching (PSM) was conducted. RESULTS: In resectable disease, the NAT group showed better overall survival (OS) compared with the upfront group. Multivariate analysis identified CA19-9 level (≥100 U/mL) and lymph node metastasis to be prognostic factors, and a tumor size of 25 mm was the optimal cut-off value to predict lymph node metastasis. There was no significant survival difference between patients with a tumor size ≤25 mm and CA19-9 < 100 U/mL and those in the NAT group. In borderline resectable disease, OS in the NAT group was significantly better than that in the upfront group. CEA (≥5 ng/mL) and CA19-9 (≥100 U/mL) were identified as prognostic factors; however, the OS of patients fulfilling these factors was worse than that of the NAT group. CONCLUSIONS: NAT could be unnecessary in patients with tumor size ≤25 mm and CA19-9 < 100 U/mL in resectable disease. In borderline resectable disease, surgery should be delayed until tumor marker levels are well controlled.

OBJECTIVE: We investigated whether pretreatment systemic inflammatory markers are associated with survival outcomes in patients with endometrial cancer (EC). METHODS: Data from the Japanese Gynecologic Oncology Group 2043 were analyzed. Patients who did not receive chemotherapy or were lost to follow-up were excluded. Associations of pretreatment systemic inflammatory markers, including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and hemoglobin, albumin, lymphocyte, and platelet (HALP) score, with progression-free survival (PFS) and overall survival (OS) were analyzed. The optimal NLR, PLR, and HALP score cutoff values for PFS and OS were determined. Survival estimates were calculated and compared using the Kaplan-Meier method and log-rank test. RESULTS: We included 712 patients (median age: 55 [range, 28-74] years; body mass index [BMI]: 21.1 [15.2-38.6] kg/m2). For PFS, optimal NLR, PLR, and HALP score cutoff values were 1.48, 0.017, and 35.52, respectively, and for OS, the values were 1.88, 0.026, and 19.87, respectively. At optimal PFS-related cutoff values, NLR was associated with BMI; PLR with age, BMI, and clinical stage; and HALP score with BMI, clinical stage, and lymph node metastasis. At optimal OS-related cutoff values, NLR was associated with BMI, PLR, and BMI; the HALP score was associated with age and BMI. The HALP score was a prognostic factor for PFS (p = 0.025), while PLR and HALP scores were prognostic factors for OS (both p = 0.028). CONCLUSIONS: Pretreatment systemic inflammatory markers are associated with survival outcomes in patients with EC, with the HALP score being a prognostic factor for PFS and OS.

The HECT-type ubiquitin E3 ligases including ITCH regulate many aspects of cellular function through ubiquitinating various substrates. These ligases are known to be allosterically autoinhibited and to require an activator protein to fully achieve the ubiquitination of their substrates. Here we demonstrate that FAM189A2, a downregulated gene in breast cancer, encodes a new type of ITCH activator. FAM189A2 is a transmembrane protein harboring PPxY motifs, and the motifs mediate its association with and ubiquitination by ITCH. FAM189A2 also associates with Epsin and accumulates in early and late endosomes along with ITCH. Intriguingly, FAM189A2 facilitates the association of a chemokine receptor CXCR4 with ITCH and enhances ITCH-mediated ubiquitination of CXCR4. FAM189A2-knockout prohibits CXCL12-induced endocytosis of CXCR4, thereby enhancing the effects of CXCL12 on the chemotaxis and mammosphere formation of breast cancer cells. In comparison to other activators or adaptors known in the previous studies, FAM189A2 is a unique activator for ITCH to desensitize CXCR4 activity, and we here propose that FAM189A2 be renamed as ENdosomal TRansmembrane binding with EPsin (ENTREP).

Well-differentiated endometrioid carcinoma (EC) is a low-grade cancer with relatively indolent behavior. However, even with well-differentiated histology, it sometimes tends to invade extensively and shows metastatic potential, suggesting that this is a group of cancers with heterogeneous behavior. In contrast, due to its tendency for younger onset, the treatment strategy for EC frequently considers fertility preservation, highlighting the need for a more accurate evaluation of myometrial invasion through biopsy and imaging diagnostics. We previously reported the involvement of the CXCR4-CXCL12 and CXCL14 axes in EC invasion. Accordingly, we investigated whether CXCR4 expression could reflect invasive potential and explored its interaction with cancer-associated fibroblasts that produce chemokines in the tumor microenvironment. Immunohistochemical expression of CXCR4 was assessed in 71 cases of EC (14 of EC confined to the endometrium and 57 of myoinvasive EC), 6 cases of endometrial intraepithelial neoplasia, and 42 cases of noncarcinomatous conditions. CXCR4 expression was significantly higher in myoinvasive EC than in noncancerous conditions, endometrial intraepithelial neoplasia, and endometrium-confined EC. By univariate and multivariate analysis, CXCR4 expression significantly reflected myometrial invasion. CXCR4 expression in the biopsied and resected specimens correlated weakly positively. Invasion and wound-healing assays were performed culturing an EC cell line in a cancer-associated fibroblast-conditioned medium. The invasion and wound-healing potentials were dependent on CXCR4 and cancer-associated fibroblast. Our study demonstrated that CXCR4 expression is an independent factor in myometrial invasion and can support diagnostic evaluation before treatment in the biopsy sample.
RESUMO
BACKGROUND: Large type 3 (diameter ≥ 8 cm) and type 4 gastric cancers have been arbitrarily combined in Japan as a single entity. However, whether these two types are oncologically similar remain unclear. This study aimed to clarify this issue. METHODS: In this retrospective study, we analyzed a database of 3,575 patients from nine institutions who underwent gastrectomy between 2010 and 2014. Using propensity scores to balance significant variables, we compared prognoses and tumor recurrences. RESULTS: Of patients with clinical T3/T4 who underwent R0 resection, 75 and 73 had large type 3 and 4 tumors, respectively. Patients with type 4 tumors had significantly lower overall survival rates than those of patients with large type 3 tumors (hazard ratio [HR] 1.77; 95% confidence interval [CI] 1.14-2.74). However, among the large type 3 tumors, a remarkable difference in prognosis was observed between the differentiated and undifferentiated histological types. A comparison was made between large type 3 with undifferentiated phenotype and type 4, each with 39 patients after propensity score matching. Outcomes in both groups were similar in terms of overall survival (HR 1.28; 95% CI 0.73-2.25) and relapse-free survival (HR 1.34; 95% CI 0.80-2.27). No statistically significant differences were observed in the incidence of peritoneal recurrence (35.9% vs. 46.1%, P = 0.36) and lymph node recurrence (25.6% vs. 12.8%, P = 0.15). CONCLUSIONS: Large type 3 tumors with undifferentiated phenotype and type 4 tumors were oncologically similar. This subgroup could be considered as a new entity for future clinical trials.
RESUMO
BACKGROUND: Proximal gastrectomy (PG) has become an increasingly preferred procedure for treating early cancer in the upper third of the stomach. However, advantages of PG in postoperative quality of life (QOL) over total gastrectomy (TG) has not fully proven. METHODS: We conducted a multi-institutional prospective observational study (CCOG1602) of patients who undergo TG or PG for cStage I gastric cancer. We used the PGSAS-37 and EORTC-QLQ-C30 to evaluate the changes in body weight and QOL over a 3-year postoperative period. The primary endpoint was the weight loss rate 3 years after surgery. RESULTS: We enrolled 109 patients from 18 institutions and selected 65 and 19 patients for inclusion in the TG and PG groups, respectively. Mean postoperative weight loss rates were 16.0% and 11.7% for the TG and PG groups, respectively (p = 0.056, Cohen's d 0.656) during postoperative year 1% and 15.0% and 10.8% for TG and PG (p = 0.068, Cohen's d 0.543), respectively, during postoperative year 3, indicating that the PG group achieved a better trend with a moderate effect size. According to the PGSAS-37, the PG group experienced a better trend in the indigestion subscale (p < 0.001, Cohen's d -1.085) and total symptom score (p = 0.050, Cohen's d -0.59) during postoperative year 3 compared with the TG group. In contrast, the EORTC-QLQ-C30 detected no difference between the groups at any time point during 3-year postoperative period. CONCLUSIONS: This prospective study demonstrates that PG tended to be more favorable compared with TG with respect to postoperative weight loss and QOL, particularly regarding indigestion.

PURPOSE: A collapse in regional healthcare through the maldistribution of physicians has been a long-debated issue in Japan and amidst this situation, a new system of board certification was initiated. The Japan Surgical Society (JSS) conducted a nation-wide survey to grasp the current distribution of surgeons in Japan, and their roles. METHODS: All 1976 JSS-certified teaching hospitals were invited to respond to a web-based questionnaire. The responses were analyzed to seek a solution to the current issues. RESULTS: Responses to the questionnaire were received from 1335 hospitals. The surgical departments of medical universities serve as an internal labor market and were the source of surgeons for most hospitals. More than 50% of teaching hospitals throughout the country claimed a shortage of surgeons even in well-populated prefectures such as Tokyo and Osaka. Hospitals rely on surgeons to cover the deficits in medical oncology, anesthesiology, and emergency medicine. These additional responsibilities were identified as significant predictors of a shortage of surgeons. CONCLUSIONS: Surgeon shortage is a serious issue throughout Japan. Given the limited number of surgeons and surgical trainees, hospitals should make every effort to recruit specialists in the additional fields where surgeons are filling the gaps and allow surgeons to engage more in surgery.

PURPOSE: While regarded as function-preserving gastrectomy, few prospective longitudinal clinical trials have addressed the postoperative quality of life (QOL) after pylorus-preserving gastrectomy (PPG). We prospectively compared chronological changes in postoperative body weight and the QOL between PPG and distal gastrectomy (DG) for pathological Stage I gastric cancer (GC). METHODS: We conducted a multi-institutional prospective study (CCOG1601) to evaluate patients who underwent DG and PPG. The QOL was examined using the European Organization for Research and Treatment of Cancer Quality of life questionnaire-C30 (EORTC QLQ-C30) and the Post-Gastrectomy Syndrome Assessment Scale-37 (PGSAS-37). A total of 295 patients were enrolled from 15 institutions, and propensity score matching was performed to adjust for the essential variables for comparison analyses. RESULTS: After propensity score matching, 25 pairs of patients were identified. In the first postoperative month, DG achieved a superior nausea and vomiting score (EORTC QLQ-C30) and meal-related distress, indigestion, and dumping scores (PGSAS-37). No significant differences were noted between DG and PPG in the long-term QOL. Postoperative body weight loss was similar in both groups. CONCLUSIONS: This prospective observational study failed to demonstrate the superiority of PPG over DG in terms of postoperative body weight changes and the QOL.
RESUMO
OBJECTIVE: This study investigated the prognostic factors of anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis (MDA5-DM). METHODS: This study analysed 34 MDA5-DM cases (20 and 14 in the survival and death groups, respectively) encountered at Kurume University between 2008 and 2021. The clinical, physiological, and computed tomography findings, pulmonary function, and serological results were retrospectively evaluated for each MDA5-DM case during the first visit and throughout the next 12 weeks. RESULTS: In the death group, the mean age of patients was higher (47.6 vs. 61.8 years), while the duration from symptom onset to consultation was shorter (110 vs. 34.9 days). During the first visit, the death group demonstrated a significantly higher serum C-reactive protein level (0.52 vs. 1.99) and a significantly lower albumin level (3.23 vs. 2.63) than the survival group; this persisted throughout the next 12 weeks. Poor prognosis was associated with C-reactive protein and albumin levels >0.19 mg/dl and <2.3 g/dl, respectively, 4 weeks after starting the treatment. CONCLUSION: Four weeks after starting the treatment, serum C-reactive protein and albumin levels of patients with MDA5-DM can be used to evaluate treatment response and predict prognosis.

BACKGROUND: The optimal range of serum iron markers and usefulness of iron supplementation are uncertain in patients with pre-dialysis chronic kidney disease (CKD). We investigated the association between serum iron indices and risk of cardiovascular disease (CVD) events and the effectiveness of iron supplementation using Chronic Kidney Disease Japan Cohort data. METHODS: We included 1416 patients ages 20-75 years with pre-dialysis CKD. The tested exposures were serum transferrin saturation and serum ferritin levels and the outcome measures were any cardiovascular event. Fine-Gray subdistribution hazard models were used to examine the association between serum iron indices and time to events. The multivariable fractional polynomial interaction approach was used to evaluate whether serum iron indices were effect modifiers of the association between iron supplementation and cardiovascular events. RESULTS: The overall incidence rate of CVD events for a median of 4.12 years was 26.7 events/1000 person-years. Patients with serum transferrin saturation <20% demonstrated an increased risk of CVD [subdistribution hazard ratio (HR) 2.13] and congestive heart failure (subdistribution HR 2.42). The magnitude of reduction in CVD risk with iron supplementation was greater in patients with lower transferrin saturations (P = .042). CONCLUSIONS: Maintaining transferrin saturation >20% and adequate iron supplementation may effectively reduce the risk of CVD events in patients with pre-dialysis CKD.

BACKGROUND: The number of patients who die from causes other than gastric cancer after R0 resection is increasing in Japan, due in part to the aging population. However, few studies have comprehensively investigated the clinicopathological risks associated with deaths from other causes after gastrectomy. This study aimed to build a risk score for predicting such deaths. METHODS: We retrospectively reviewed clinical data for 3575 patients who underwent gastrectomy for gastric cancer at nine institutions in Japan between January 2010 and December 2014. RESULTS: The final study population of 1758 patients were assigned to Group A (n = 187): patients who died from other causes within 5 years of surgery, and Group B (n = 1571): patients who survived ≥ 5 years after surgery. Multivariate analysis identified nine characteristics as risk factors for poor survival: age ≥ 75 years, male sex, body mass index < 22 kg/m2, Eastern Cooperative Oncology Group Performance Status (≥ 1), diabetes mellitus, cardiovascular/cerebrovascular disease, other malignant diseases, preoperative albumin level < 3.5 g/dL, and total gastrectomy. Patients with risk scores of 0-2, 3-4, or 5-9 (based on 1 point per characteristics) were classified into Low-risk, Intermediate-risk, and High-risk groups, respectively. The 5-year survival rates were 96.5%, 85.3%, and 56.5%, for the Low-, Intermediate-, and High-risk groups, respectively, and the hazard ratio (95% confidence intervals) was 16.33 (10.85-24.58, p < 0.001) for the High-risk group. CONCLUSIONS: The risk score defined here may be useful for predicting deaths from other causes after curative gastrectomy.

PURPOSE: To investigate the effects of an original education program on patients with epilepsy (PWE). The effects on knowledge about epilepsy, attitude to epilepsy, depression scales, and quality of life were investigated. METHOD: Thirty-five PWE participated in a lecture-style educational program using an original knowledge-oriented textbook. All patients were administered a total of four rating scales: the Knowledge about Epilepsy Scale (KES), the Attitude toward Epilepsy Scale (AES), and the Japanese version of the Quality of Life in Epilepsy Inventory (QOLIE-31-P), the Beck Depression Inventory (BDI). The KES and AES of patients (pKES and pAES) were compared to those of medical students (St) and residents (Rd). RESULTS: After education, pKES improved and showed significant differences among pre-and post-education and six months later. Before education, pKES was inferior to St and Rd. However, after education, pKES changed and became superior to St and Rd. Six months later, the advantage was lost, but not significantly. PAES also improved after education, with significant differences before, after, and six months later after education. PAES was statistically inferior to St and Rd before education, but the difference disappeared after education, and the effect persisted after six months. The non-depressed (BDI < 20) and depressed groups (BDI ⧠20) improved in the KES after education. About the AES, the non-depressive group has a statistical tendency, but not the depressive group. At six months, the depressed group's AES is significantly lower than the non-depressed group. CONCLUSION: While correct knowledge about epilepsy can improve attitudes and perceptions of epilepsy in PWE, special measures are needed for PWE with depression.

Hepatocyte growth factor (HGF) is an adipocytokine elevated in obese subjects. We have previously reported that serum HGF levels were significantly associated with insulin resistance or components of the metabolic syndrome. However, it has been unknown how physical activity (PA) affects HGF levels after a long-term follow-up. Our aim was to clarify the association between PA changes and HGF levels as well as cerebro-cardiovascular disease (CVD) development, during a 10 year follow-up period in a Japanese general population. Of 1320 subjects who received a health check-up examination in Tanushimaru town in 1999, 903 subjects (341 males and 562 females), who received the examination both in 1999 and 2009 were enrolled. We evaluated their PA levels by Baecke questionnaire in 1999 and by a simple questionnaire in 2009. We measured the HGF levels by ELISA method in 1999 and 2009. We divided the subjects into four PA groups, stable low PA, increased PA, decreased PA, and stable high PA. Using these questionnaires, we compared their PA and HGF levels after an interval of 10 years. A significant inverse association was found between PA changes and HGF levels at 10 years, after adjustment for age and sex. The HGF levels of the increased PA group were significantly lower than stable low PA (p = 0.038), and the increased PA group showed reduced CVD development compared to the stable low PA group after adjustment for age and sex (p = 0.012). Our data demonstrated that improvement of PA levels was associated with reduced HGF levels and CVD development.

INTRODUCTION: Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 are widely used for treating various cancers, with cutoff values of 5.0 ng/mL and 37.0 IU/mL, respectively. However, these cutoff values are not for specific diseases or purposes but are uniformly used for any disease and any purpose. It is also unclear as to whether patients are at equal risk of recurrence if they are below the cutoff values. This study aimed to investigate the optimal cutoff of serum tumor markers in the stratification of recurrence risk after curative resection of gastric cancer. METHODS: We constructed a nine-center integrated database of patients who received gastrectomy between January 2010 and December 2014 with a 5-year follow-up period. We determined the cutoff value of preoperative serum tumor marker levels correlated with postoperative recurrences and evaluated its performance in risk stratification for recurrences in 948 patients with stage II/III gastric cancer who underwent radical resection. RESULTS: The hazard ratio for postoperative recurrences increased at two points of preoperative CEA levels, 3.6 ng/mL and 5.0 ng/mL, which were set as cutoffs. These two cutoffs stratified relapse-free survival into three levels. CONCLUSIONS: By adding a second cutoff value for preoperative serum CEA, which was proposed specifically for the prediction of recurrences, patients can be stratified into low-, intermediate-, and high-risk recurrences after curative resection of gastric cancer.

BACKGROUND: The purpose of this study was to evaluate the clinical performance of Digital Breast Tomosynthesis guided vacuum-assisted biopsy (DBT-VAB) for microcalcifications in the breast. METHODS: Retrospective review of 131 mammography-guided VABs at our institution were performed. All of the targets were calcification lesion suspicious for cancer. 45 consecutive stereotactic vacuum-assisted biopsies (ST-VABs) and 86 consecutive DBT-VABs were compared. Written informed consent was obtained. Tissue sampling methods and materials were the same with both systems. Student's t-test was used to compare procedure time and the Fisher's exact test was used to compare success rate, complications, and histopathologic findings for the 2 methods. RESULTS: The tissue sampling success rate was 95.6% for ST-VAB (43/45) and 97.7% (84/86) for DBT-VAB. Time for positioning (10.6 ± 6.4 vs. 6.7 ± 5.3 min), time for biopsy (33.4 ± 13.1 vs. 22.5 ± 13.1 min), and overall procedure time (66.6 ± 16.6 min vs. 54.5 ± 13.0 min) were substantially shorter with DBT-VAB (P < 0.0001). There were no differences in the distribution of pathological findings between the 2 groups. CONCLUSION: Depth information and stable visibility of the target provided by DBT images led to quick decisions about target coordinates and improved the clinical performance of microcalcification biopsies.

BACKGROUND: Nintedanib is now widely used to treat interstitial lung disease (ILD). Adverse events, which occur in not a few patients, make it difficult to continue nintedanib treatment, but the risk factors for adverse events are not well understood. METHODS: In this retrospective cohort study, we enrolled 111 patients with ILDs treated with nintedanib and investigated the factors involved in starting dosage reduction, withdrawal, or discontinuation within 12 months, even with appropriate symptomatic treatment. We also examined the efficacy of nintedanib in reducing the frequency of acute exacerbations and the prevention of pulmonary function reduction. RESULTS: Patients with high monocyte counts (> 0.454 × 109/L) had a significantly higher frequency of treatment failure, such as dosage reduction, withdrawal, or discontinuation. High monocyte count was as significant a risk factor as body surface area (BSA). Regarding efficacy, there was no difference in the frequency of acute exacerbations or the amount of decline in pulmonary function within 12 months between the normal (300 mg) and reduced (200 mg) starting dosage groups. CONCLUSION: Our study results indicate that patients with higher monocyte counts (> 0.454 × 109/L) should very careful about side effects with regard to nintedanib administration. Like BSA, a higher monocyte count is considered a risk factor for nintedanib treatment failure. There was no difference in FVC decline and frequency of acute exacerbations between the starting doseage of nintedanib, 300 mg and 200 mg. Considering the risk of withdrawal periods and discontinuation, a reduced starting dosage may be acceptable in the patients with higher monocyte counts or small body sizes.

BACKGROUND: Cholecystitis can represent a comorbidity during gallbladder cancer surgery; nonetheless, the prognostic impact of acute cholecystitis comorbidity remains unclear. This study aimed to evaluate the impact of acute cholecystitis comorbidity on prognosis after gallbladder cancer surgery, with adjustment for background factors using propensity score analysis. METHODS: A total of 218 patients who underwent gallbladder cancer surgery at our institute between 1986 and 2022 were retrospectively included in the analysis. Patients were divided into two groups according to the presence or absence of acute cholecystitis at the time of surgery. Background factors were adjusted by including intraoperative bile leakage as a covariate in propensity score calculation. Overall survival and recurrence-free survival were compared between the two groups using one-to-one propensity score matching and inverse probability weighting. RESULTS: Of the 218 patients, 37 had coexisting acute cholecystitis. In one-to-one propensity score matching, the overall survival time in the acute cholecystitis group tended to be shorter than that in the non-acute cholecystitis group, although not significantly (hazard ratio, 2.41; 95% confidence interval, 0.96-6.06). Other analyses using inverse probability weighting showed significantly poor overall survival in the acute cholecystitis group. Regarding recurrence-free survival in propensity score matching, the acute cholecystitis group showed a significantly shorter duration than the non-acute cholecystitis group (hazard ratio, 6.69; 95% confidence interval, 1.46-30.6). The inverse probability weighting-adjusted analysis also indicated a significantly higher risk of recurrence in the acute cholecystitis group. CONCLUSIONS: Acute cholecystitis comorbidity at the time of gallbladder cancer surgery may have a negative impact on gallbladder cancer prognosis.

PURPOSE: The efficiency and safety of routine intravenous administration of acetaminophen after highly invasive hepatobiliary pancreatic surgery remain unclear. In particular, there have been no studies focusing on pancreatoduodenectomy. The present study clarified its clinical utility for patients undergoing pancreatoduodenectomy. METHODS: We retrospectively collected 179 patients who underwent open pancreatoduodenectomy from 2015 to 2020. The analgesic effects and adverse events in patients with scheduled intravenous administration of acetaminophen were evaluated using propensity score matching. RESULTS: After 40 patients from each group were selected by propensity score matching, the postoperative liver function tests were not significantly different between the control and acetaminophen groups. No significant differences were found in the self-reported pain intensity score or postoperative nausea and vomiting; however, the rate of pentazocine use and the total number of additional analgesics were significantly lower in the acetaminophen group than in the control group (p = 0.003 and 0.002, respectively). CONCLUSION: The scheduled intravenous administration of acetaminophen did not affect the postoperative liver function and had a good analgesic effect after pancreatoduodenectomy.

PURPOSE: Peritoneal dissemination is the key to the prognosis of gastric cancer (GC) and can be detected early with peritoneal lavage cytology. No studies have examined preoperative prognostic factors in GC patients who have positive cytology but no other non-curative factors. METHODS: We conducted a retrospective analysis using a multicenter database of 3575 patients who underwent gastrectomy between 2010 and 2014. Patients with positive peritoneal lavage cytology as a sole non-curative factor were retrieved, and correlations between parameters and the prognosis were compared. RESULTS: A total of 66 patients were identified as eligible. In the receiver operating characteristic (ROC) curve analysis, the neutrophil-to-platelet ratio (NPR) had the greatest area under the curve value and was selected. We divided the NPR into two groups based on the optimal cutoff value of the NPR (2.000), as determined by the ROC curve analysis. A high preoperative NPR was the only prognostic factor. The NPR-high group had shorter overall survival than the NPR-low group (hazard ratio 1.85, 95% confidence interval 1.05-3.28, P = 0.032). CONCLUSION: Our analysis indicated that the preoperative NPR serves as a prognostic factor in GC patients with positive peritoneal lavage cytology in the absence of other non-curative factors.

PURPOSE: The albumin-bilirubin (ALBI) grade is calculated using albumin and bilirubin values. We determined the optimal cutoff value of the ALBI grade for predicting the postoperative prognosis of gastric cancer (GC). METHODS: We retrospectively reviewed a multicenter database of 3571 patients who underwent gastrectomy for GC between January 2010 and December 2014. The modified ALBI (mALBI) grade was determined using cutoff values: grade 1 (mALBI ≤ - 2.70), 2 (mALBI - 2.70 to - 2.10), and 3 (mALBI > - 2.10). We used a validation cohort to evaluate reproducibility. RESULTS: The entire cohort (n = 956) was randomly assigned to the learning or validation cohorts (n = 478 each). The former was categorized into the following groups by the preoperative mALBI grade: grade 1 (n = 235), grade 2 (n = 162), and grade 3 (n = 81). The disease-specific survival (DSS) rates of the learning and validation cohorts were significantly shortened in association with higher mALBI grade (learning, p = 0.0068; validation, p = 0.0100). A multivariate analysis revealed that mALBI grade 3 served as an independent prognostic factor for DSS. Furthermore, mALBI grade 2 or 3 was associated with a greater risk of disease-specific death in most subgroups. CONCLUSION: The mALBI grade accurately predicted the long-term postoperative prognosis of locally advanced GC.
