Fusobacterium nucleatum promotes esophageal squamous cell carcinoma progression via the NOD1/RIPK2/NF-κB pathway. Cancer Lett 2022; 530:59-67.

Abstract
Fusobacterium nucleatum, found in the oral cavity, influences the progression of gastrointestinal cancers. Additionally, our previous results suggested that F. nucleatum is associated with poor patient prognosis in esophageal squamous cell carcinoma (ESCC). However, the mechanism by which F. nucleatum affects aggressive tumor behavior has yet to be elucidated. We have conducted this clinical, in vitro, and in vivo study to clarify the mechanism of ESCC progression induced by F. nucleatum. Transmission electron microscopy revealed that F. nucleatum invaded and occupied ESCC cells and impacted gene and protein expression. Comprehensive mRNA expression and pathway enrichment analyses of F. nucleatum-treated ESCC cells identified the "NF-κB" and "NOD-like receptor" signaling pathways as enriched. We confirmed the relationship between the presence of F. nucleatum and NF-κB activation in resected ESCC tissues. Furthermore, F. nucleatum-treated ESCC cells demonstrated enhanced growth ability, and NF-κB activation, as well as overexpression of NOD1 and phosphorylated RIPK2. Furthermore, treated cells showed accelerated tumor growth, with NF-κB activation in xenograft models. F. nucleatum invaded ESCC cells and induced the NF-κB pathway through the NOD1/RIPK2 pathway, leading to tumor progression.

Abstract
The objective of this single-center retrospective cohort study was to investigate the relationship between blood transfusion and persistent inflammation, immunosuppression, and catabolism syndrome (PIICS). The study was conducted at the Critical Care Center at Toho University Omori Medical Center, Japan. We included 391 patients in the PIICS group (hospitalization for > 15 days, C-reactive protein > 3.0 mg/dL or albumin < 3.0 mg/dL or lymph < 800/μL on day 14) and 762 patients in the non-PIICS group (hospitalization for > 15 days and not meeting the PIICS criteria). We performed univariate and multivariate logistic regression analyses using PIICS as the objective variable and red blood cell (RBC) or fresh frozen plasma or platelet (PLT) transfusion and other confounding factors as explanatory variables. In addition, we conducted a sensitivity analysis using propensity score matching analysis. The multivariate and propensity score analyses showed that RBC and PLT transfusions were significantly associated with PIICS. This is the first study to report an association between RBC and PLT transfusions and PIICS. Our findings have contributed to better understanding the risk factors of PIICS and suggest that physicians should consider the risk of PIICS occurrence when administering blood transfusions in intensive care unit (ICU) patients.

Abstract
BACKGROUND Preoperative malnutrition is believed to contribute to increased postoperative complications. Preoperative serum prealbumin level was reported to be a predictor of nutritional status and postoperative complications after gastrointestinal surgery, including gastrectomy. Gastric outlet obstruction caused by gastric cancer leads to insufficient nutritional status. However, the impact of preoperative enteral nutrition using naso-jejunal feeding tubes for patients with gastric outlet obstruction is not fully understood. METHODS From July 2010 to June 2020, 50 patients with gastric cancer-induced outlet obstruction who underwent gastrectomy following preoperative enteral nutrition via feeding tube were included. We investigated the relationship between changes in nutritional status after preoperative enteral nutrition and postoperative complications. Postoperative complications were defined as grade ≥II based on the Clavien-Dindo classification. RESULTS The median period of preoperative enteral nutrition was 10 days. The median increase rate of the serum prealbumin level was 10.5% (interquartile range, 0.63-38.2%), and patients with an increase rate ≥ 10% were defined as the elevated group. Postoperative morbidity was significantly higher in the non-elevated group (P = 0.0031). Univariate and multivariate analyses showed that an increased rate of the serum prealbumin level was an independent risk factor of postoperative complications for patients with gastric outlet obstruction caused by gastric cancer (P = 0.0025 and P = 0.009, respectively). CONCLUSIONS Preoperative enteral nutrition improved the serum prealbumin level of patients with gastric cancer-induced outlet obstruction, and an increased rate of prealbumin can be an indicator of sufficient preoperative enteral nutrition and decreased postoperative morbidity.

Abstract
AIM Digestive reconstruction after pharyngolaryngectomy with total esophagectomy (PLTE) remains challenging, with the optimal method remaining unclear. The current study aimed to clarify the short-term outcomes after PLTE and determine the optimal digestive reconstruction method. METHODS Based on a nationwide survey of 151 patients who underwent PLTE, outcomes of digestive reconstruction methods are described. RESULTS Among digestive reconstruction methods, a simple gastric tube was most frequently used (37.1%), followed by gastric tube combined with free graft transfer (FGT) (35.1%), gastric tube with microvascular anastomosis (22.5%), and other procedures (5.3%). Intraoperative evaluation of microcirculation (IOEM) was utilized in 29 patients (19.2%). Among the included patients, 66.9% developed any-grade complications, 41.0% developed severe complications, and 23.8% developed digestive reconstruction-related complications (DRRCs; leakage or necrosis). Reoperation within 30 days for any complications and DRRCs was required in 13.9% and 8.6% of the patients, respectively. Mortality within 90 days was observed in 4.6%. Among the three major methods, gastric tube combined with FGT promoted the least DRRCs in the gastric tube (P = .005), although the overall incidence of DRRCs was comparable. The use of IOEM was significantly associated with a reduction of severe DRRCs (P = .005). CONCLUSIONS Pharyngolaryngectomy with total esophagectomy is a high-risk surgery significantly associated with the occurrence of postoperative morbidity and mortality. Nonetheless, the addition of FGT can help prevent gastric tip complications, while IOEM can be an effective method for improving outcomes.

Abstract
BACKGROUND The registration committee for esophageal cancer in the Japan Esophageal Society (JES) has collected the patients' characteristics, treatment, and outcomes annually. METHODS We analyzed the data of patients who had visited the participating hospitals in 2014. We collected the data with a web-based data collection system using the National Clinical Database. We used the Japanese Classification of Esophageal Cancer 10th edition by JES and the TNM classification 7th edition by the Union of International Cancer Control (UICC) for cancer staging. RESULTS A total of 9026 cases were registered from 344 institutions in Japan. Squamous cell carcinoma and adenocarcinoma accounted for 87.9% and 7.1%, respectively. The 5-year survival rates of patients treated using endoscopic resection, concurrent chemoradiotherapy, radiotherapy alone, and esophagectomy were 87.1%, 33.7%, 25.3%, and 59.3%, respectively. Esophagectomy was performed in 5204 cases. Concerning the approach used for esophagectomy, 48.1% of the cases were treated thoracoscopically. The operative mortality (within 30 days after surgery) was 0.75%, and the hospital mortality was 2.0%. The survival curves showed an excellent discriminatory ability both in the clinical and pathologic stages by the JES system. The survival of pStage IV was better than IIIC in the UICC system, because pStage IV included the patients with supraclavicular lymph-node metastasis (M1 LYM). CONCLUSION We hope that this report contributes to improving all aspects of diagnosing and treating esophageal cancer in Japan.

Abstract
The first measurements of differential branching fractions of inclusive semileptonic B→X_{u}ℓ^{+}ν_{ℓ} decays are performed using the full Belle data set of 711 fb^{-1} of integrated luminosity at the ϒ(4S) resonance and for ℓ=e, μ. With the availability of these measurements, new avenues for future shape-function model-independent determinations of the Cabibbo-Kobayashi-Maskawa matrix element |V_{ub}| can be pursued to gain new insights in the existing tension with respect to exclusive determinations. The differential branching fractions are reported as a function of the lepton energy, the four-momentum-transfer squared, light-cone momenta, the hadronic mass, and the hadronic mass squared. They are obtained by subtracting the backgrounds from semileptonic B→X_{c}ℓ^{+}ν_{ℓ} decays and other processes, and corrected for resolution and acceptance effects.

Abstract
BACKGROUND/AIM Treatments containing ipilimumab have shown a good outcome in patients with non-small cell lung cancer (NSCLC) regardless of the PD-L1 tumor proportion score (TPS). However, the association between PD-L1 TPS and the expression of CTLA-4 in tumor-infiltrating lymphocytes is unknown. PATIENTS AND METHODS Fifty-five NSCLC patients who underwent surgery in our hospital were included in this study. We measured the proportions of CTLA-4+ regulatory T cells, and CTLA-4+ CD8 T cells, and statistically analyzed their correlations with the PD-L1 TPS. RESULTS Statistical correlations were found neither between the proportion of CTLA-4+ regulatory T cells to CD8 T cells and the PD-L1 TPS (p=0.2859) nor between the proportion of CTLA-4+ cells in CD8 T cells and the PD-L1 TPS (p=0.1919). CONCLUSION The proportions of CTLA-4+ regulatory T cells to CD8 T cells and CTLA-4+ cells in CD8 T cells were irrelevant to the PD-L1 TPS in NSCLC patients.

Abstract
Robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal cancer has been performed increasingly frequently over the last few years. Robotic systems with articulated devices and tremor filtration allow surgeons to perform such procedures more meticulously than by hand. The feasibility of RAMIE has been demonstrated in several retrospective comparative studies, which showed similar short-term outcomes to conventional minimally invasive esophagectomy (cMIE). Considering the number of harvested lymph nodes, RAMIE may be superior to cMIE in terms of left upper mediastinal lymph node dissection. However, whether or not the addition of a robotic system to cMIE can help improve perioperative and oncological outcomes remains unclear. Given the lack of established evidence from randomized controlled trials, we must await the results of ongoing studies to reach any meaningful conclusions. Further advancements in robotic platforms, as well as the reduction in medical expenses, will be essential to demonstrate the real benefit of RAMIE.

Abstract
We report a measurement of the D^{0} and D^{+} lifetimes using D^{0}→K^{-}π^{+} and D^{+}→K^{-}π^{+}π^{+} decays reconstructed in e^{+}e^{-}→cc[over ¯] data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy e^{+}e^{-} collider. The data, collected at center-of-mass energies at or near the ϒ(4S) resonance, correspond to an integrated luminosity of 72 fb^{-1}. The results, τ(D^{0})=410.5±1.1(stat)±0.8(syst) fs and τ(D^{+})=1030.4±4.7(stat)±3.1(syst) fs, are the most precise to date and are consistent with previous determinations.

Abstract
Immune checkpoint inhibitors have shown efficacy in various cancers. Although programmed death ligand 1/2 (PD‐L1/L2) expressions have been demonstrated as predictive biomarkers of response to immune checkpoint inhibitors and prognostic markers, whether PD‐L1/L2 expression is altered in esophageal squamous cell carcinoma during the therapeutic course is unclear. Whether PD‐L1/L2 expression in metastatic or recurrent lesions is consistent with that in primary tumors is also unknown. This study included 561 surgically resected esophageal squamous cell carcinomas and PD‐L1/L2 expression was evaluated by immunohistochemistry. We investigated the influence of chemotherapeutic drugs (cisplatin and fluorouracil) on PD‐L1/L2 expression and PD‐L1/L2‐related pathways in vitro. We also examined PD‐L1/L2 expression in 18 surgically resected lymph node metastases and 10 recurrent lesions compared with primary lesions. The positive rate of PD‐L1 was significantly higher in patients with preoperative chemotherapy than in those without preoperative therapy. The positive rate of PD‐L2 expression showed no significant difference between patient groups. Cisplatin increased PD‐L1 expression in cancer cell lines in vitro, but decreased PD‐L2 in some cell lines. The effects of cisplatin on phosphorylated signal transducer and activator of transcription 1/3 (pSTAT1/3) also differed depending on cell lines. Fluorouracil increased PD‐L1 and PD‐L2 expression. PD‐L1/L2 expression in lymph node metastases and recurrent lesions did not always match expression in primary lesions. PD‐L1/L2 expression may be altered by preoperative chemotherapy, and PD‐L1 /L2 expression in primary lesions does not always match that of metastatic/recurrent lesions. Thus, one‐time evaluation is not sufficient to evaluate PD‐L1/L2 expression as a biomarker in esophageal cancer.

Patients with vertebral artery injury from penetrating neck trauma may not present with signs of vascular injury because of anatomical characteristics and concomitant conditions, such as hypothermia and shock. If patients are hemodynamically stable, imaging tests should be performed to examine the posterior components, including the vertebral artery.

Abstract
PURPOSE The purpose of this study was to clarify the clinical features and outcomes of patients with recurrence after esophagectomy following neoadjuvant chemotherapy (NAC) related to the timing of recurrence. METHODS We reviewed 240 consecutive patients who underwent NAC followed by esophagectomy for clinical stage II/III esophageal squamous cell carcinoma between 2009 and 2014. We compared the clinical features and survival after recurrence among groups of patients stratified by the timing of recurrence diagnosis and identified the risk factors for early recurrence (ER). RESULTS Recurrence was identified within 1 year in 61 patients and after 1 year in 23 patients. Significant differences were observed between the patients with recurrence within 1 year (early recurrence; ER) and those with recurrence after 1 year (late recurrence; LR). The ER patients had more advanced tumors and higher pretreatment serum squamous cell antigen (SCC-Ag) levels and less experienced downstaging than patients without recurrence (no recurrence; NR). Overall survival was significantly worse for the ER patients than for the LR patients. Multivariate analysis revealed that cN2-3, increased serum SCC-Ag levels, and clinical response to NAC were independent predictors of ER. CONCLUSION The ER patients had distinctive clinical features from the LR and NR patients. Extensive lymph node metastasis, an elevated SCC-Ag, and inadequate response to NAC were identified as predictors of ER.

Abstract
Abstract
Introduction
Single nucleotide polymorphisms (SNP) of endothelial nitric oxide synthase (NOS3) have been reported to be associated with diabetes mellitus and myocardial infarction. However, few reports have prospectively investigated the effects of NOS3 SNP on cardiovascular death and nonfatal myocardial infarction.
Purpose
The purpose of this study was to investigate the impact of NOS3 SNP on cardiovascular death and the development of nonfatal myocardial infarction.
Methods
This prospective cohort study included 2,752 subjects (aged ≥40) who participated in a community based health checkup. We genotyped two SNPs within NOS3 (rs1808593, rs1799983). All subjects were prospectively followed during the median follow-up period of 15.4 years with the end point of cardiovascular death and nonfatal myocardial infarction.
Results
The homozygous G-allele (GG), heterozygous (GT), and homozygous T-allele (TT) carriers of rs1808593 were identified in 60 (2%), 706 (26%), and 1,986 (72%) subjects, respectively. Kaplan-Meier analysis demonstrated that homozygous G-allele carriers of rs1808593 had the greater risk than those without. Multivariate Cox proportional hazard regression analysis revealed that the homozygous G allele of rs1808593 was associated with cardiovascular death and the development of nonfatal myocardial infarction after adjusting for confounding risk factors.
Conclusions
NOS3 gene polymorphism could be a genetic risk factor for cardiovascular death and nonfatal myocardial infarction in the Japanese general population.

Abstract
Abstract
Background
It has been reported that decreased nitric oxide bioavailability due to increased reactive oxygen species (ROS) is one of the most important causes of coronary artery spasm (CAS). Xanthine oxidoreductase (XOR) is the rate-limiting enzyme for uric acid (UA) production and plays a pivotal role in generating ROS. It was reported that the gender differences exist in the impact of serum UA levels on cardiovascular risks. We previously demonstrated that increased plasma XOR activity is significantly associated with the incidence of CAS. However, the gender differences in the impact of plasma XOR activity on CAS remain unclear.
Purpose
The aim of this study was to examine the gender differences in the clinical impact of plasma XOR activity on CAS.
Methods
We investigated plasma XOR activity in 132 patients suspected for CAS (male, n=78; female, n=54), and underwent intracoronary acetylcholine provocation test. XOR activity assay was performed using stable isotope-labeled substrate and liquid chromatography-triple quadrupole mass spectrometry. Provoked CAS was defined as total or subtotal occlusion (≥90%) with accompanying symptoms of chest pain and/or ischemic ST-segment changes on the electrocardiogram. We excluded the patients who had significant coronary artery stenosis (≥50%) and/or were taking XOR inhibitors.
Results
Plasma XOR activity was significantly lower in female compared with male patients (30.3 pmol/h/mL, interquartile range (IQR) 22.8–42.7 vs. 51.7 pmol/h/mL, IQR 34.7–101.8; P<0.001). CAS was provoked in 36 male patients and 17 female patients, and they each had significantly higher plasma XOR activity compared with those without, respectively. Multivariate logistic regression analysis showed that plasma XOR activity was independently associated with the incidence of CAS in both genders after adjustment for confounding factors. The optimal cut-off values for predicting CAS were lower in female than those in male patients (52.3 vs. 91.6 pmol/h/mL). Multivariate analysis demonstrated that female patients with high XOR activity (≥52.3 pmol/h/mL; odds ratio [OR] 22.6, P<0.001) exhibited a higher incidence of CAS compared with that in male patients (≥91.6 pmol/h/mL; OR 8.2, P<0.001).
Conclusions
Plasma XOR activity was an independent predictor for the incidence of CAS in both genders. The impact of plasma XOR activity on CAS was stronger in female patients than in male patients.

Abstract
INTRODUCTION The presence of tertiary lymphoid structure (TLS) in tumor tissues has been reported to be a factor associated with a good prognosis in several types of cancers. However, the relationship between TLS formation and peripheral blood findings remains unclear. The purposes of the study were to evaluate the effect of the presence of TLS on survival and determine the peripheral blood characteristics associated with TLS formation in non-small cell lung cancer (NSCLC) patients. METHODS A total of 147 consecutive NSCLC patients who underwent lung resection at Fukushima Medical University Hospital between 2013 and 2017 were enrolled. TLS expression was evaluated, and the relationships between clinical parameters and outcomes were analyzed. Peripheral blood mononuclear cells (PBMCs) were further analyzed by mass cytometry to characterize the TLS-positive microenvironment. RESULTS Forty-six patients had high TLS expression, and the remaining 101 patients had low TLS expression. In stage II to IV patients (n = 35), disease-free survival was longer in the high TLS expression group (p = 0.027). A low neutrophil to lymphocyte ratio (NLR) < 2.75 in the peripheral blood was associated with high TLS expression (p = 0.003). Citrus analysis after mass cytometry assay showed that the number of cells expressing HLA-DR and CD9 in PBMCs was lower in the high TLS expression group. CONCLUSION High TLS expression is associated with a good prognosis after surgery in stage II and III NSCLC patients. In the peripheral blood, a low NLR and few antigen-presenting cells indicate the presence of TLS in the tumor microenvironment.

Abstract
Using data samples of 89.5 and 711 fb^{-1} recorded at energies of sqrt[s]=10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e^{+}e^{-} collider, we report measurements of branching fractions of semileptonic decays Ξ_{c}^{0}→Ξ^{-}ℓ^{+}ν_{ℓ} (ℓ=e or μ) and the CP-asymmetry parameter of Ξ_{c}^{0}→Ξ^{-}π^{+} decay. The branching fractions are measured to be B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})=(1.31±0.04±0.07±0.38)% and B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ})=(1.27±0.06±0.10±0.37)%, and the decay parameter α_{Ξπ} is measured to be 0.63±0.03±0.01 with much improved precision compared with the current world average. The corresponding ratio B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})/B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ}) is 1.03±0.05±0.07, which is consistent with the expectation of lepton flavor universality. The first measured asymmetry parameter A_{CP}=(α_{Ξ^{-}π^{+}}+α_{Ξ[over ¯]^{+}π^{-}})/(α_{Ξ^{-}π^{+}}-α_{Ξ[over ¯]^{+}π^{-}})=0.024±0.052±0.014 is found to be consistent with zero. The first and the second uncertainties above are statistical and systematic, respectively, while the third ones arise due to the uncertainty of the Ξ_{c}^{0}→Ξ^{-}π^{+} branching fraction.

Abstract
Acute kidney injury (AKI) is a common complication in seriously ill patients, while renal ischemia-reperfusion (I/R) injury is the most frequent event in this oxidative renal injury. N-acetylcysteine (NAC) is a small molecule containing a thiol group that has antioxidant properties, promoting detoxification and acting directly as a free radical scavenger. In this study, the protective effect of NAC was investigated in short-term (30 min) and long-term (45 min) ischemic AKI. This was achieved via clamping of the renal artery for 30 or 45 min in Wistar rats to induce I/R injury. AKI worsened with a longer period of ischemia (45 compared to 30 min) due to probable irreversible damage. Preconditioning with NAC in short-term ischemia improved renal blood flow and increased creatinine clearance by reducing oxidative metabolites and increasing antioxidant capacity. Otherwise, NAC did not change these parameters in the long-term ischemia. Therefore, this study demonstrated that the period of ischemia determines the severity of the AKI, and NAC presented antioxidant effects in short-term ischemia but not in long-term ischemia, confirming that there is a possible therapeutic window for its renoprotective effect.

Abstract
BACKGROUND The adapted systemic inflammation score (aSIS), calculated from serum albumin and the lymphocyte-to-monocyte ratio, has been reported to be a novel prognostic marker for some types of cancers. However, the prognostic impact of aSIS in patients with esophageal squamous cell carcinoma (ESCC) remains controversial. This study aimed to examine the prognostic effects of aSIS in a large cohort of 509 ESCC patients. METHODS Preoperative aSIS was retrospectively calculated for 509 ESCC patients who underwent curative resection. Time-dependent receiver operating characteristics (t-ROC) curves were used for comparing the prognostic impact. RESULTS Patients with high aSIS showed significantly poorer overall survival (OS) than patients with low aSIS (log rank P < .001). The multivariate analysis revealed that aSIS was an independent prognostic factor for overall survival (multivariate hazard ratio 1.76; 95% confidence interval 1.13-2.75; P = .013). The t-ROC analysis showed that aSIS was more sensitive than other nutritional prognostic factors (controlling for nutritional status, systemic inflammation score, and the neutrophil-to-lymphocyte ratio). CONCLUSION Preoperative aSIS may be a useful prognostic biomarker in ESCC patients who underwent curative resection.

Abstract
PURPOSE A multidisciplinary treatment strategy for locally advanced esophageal squamous cell carcinoma (ESCC) is required to achieve prolonged survival. We aimed to clarify the differences in treatment strategies for locally advanced ESCC and the outcomes of elderly (aged ≥ 75 years) vs. younger patients (aged < 75 years). METHODS We compared the treatment strategy selection and the outcomes of 40 elderly and 160 younger patients with cStage II/III ESCC diagnosed between January, 2014 and December, 2016. RESULTS Nineteen (47.5%) of the elderly patients and 144 (90.0%) of the younger patients underwent esophagectomy and 9 (22.5%) of the elderly patients and 131 (81.9%) of the younger patients received neoadjuvant chemotherapy. Ivor-Lewis or transhiatal esophagectomy was performed more frequently in the elderly group than in the younger group (P = 0.0096). The survival rate after esophagectomy was higher in the younger group than in the elderly group. The overall survival rate of the elderly patients who underwent esophagectomy was significantly higher than that in those who did not. CONCLUSIONS Esophagectomy is a practical choice for elderly patients with locally advanced ESCC, although reduced treatment intensity may impact long-term survival.

Abstract
X-ray analysis is one of the most robust approaches to extract quantitative information from various materials, and is widely used in various fields ever since Raimond Castaing established procedures to analyze electron-induced X-ray signals for materials characterization 70 years ago. The recent development of aberration-correction technology in a (scanning) transmission electron microscopes (S/TEM) offers refined electron probes below the Å level, making atomic-resolution X-ray analysis possible. In addition, the latest silicon drift detectors (SDDs) allow complex detector arrangements and new configurational designs to maximize the collection efficiency of X-ray signals, which make it feasible to acquire X-ray signals from single atoms. In this review paper, recent progress and advantages related to S/TEM-based X-ray analysis will be discussed: (1) progress in quantification for materials characterization including the recent applications to light element analysis, (2) progress in analytical spatial resolution for atomic-resolution analysis and (3) progress in analytical sensitivity toward single atom detection and analysis in materials. Both atomic resolution analysis and single atom analysis are evaluated theoretically through multislice-based calculation for electron propagation in oriented crystalline specimen in combination with X-ray spectrum simulation.

Abstract
BACKGROUND Chemoradiotherapy is an alternative to surgery for esophageal cancer, with a putatively equivalent outcome. However, disease recurrence after a complete response is common and if follow-up surveillance detects recurrence, salvage treatments for potentially curable disease must follow. METHODS We conducted a nation-wide questionnaire survey of institutions in Japan certified by the Japanese Esophageal Society to investigate outcomes of primary thoracic esophageal cancer patients initially treated by chemoradiotherapy with complete response diagnoses. The primary endpoint was overall survival, the secondary endpoint disease recurrence. Outcomes of patients who had undergone salvage treatments were also investigated. Cases were excluded from analysis if endoscopic study, endoscopic biopsy, or computed tomography data were lacking. RESULTS At 41 institutes 544 case records were collected; valid data on 392 patients were obtained; 5-year survival was 74.8%, 5-year disease-free survival, 66.8%. Clinical staging before treatment significantly affected both overall and disease-free survival rates, but differences between adjoining stages were unexpectedly small. The primary relapse site was classified as primary site (n = 58), regional lymph nodes (n = 36), or distant disease (n = 34). Salvage treatments with curative intent (surgery, endoscopic treatments, and additional radiation) were performed on 38, 23, and 4 cases; 5-year survival after esophagectomy (n = 22), endoscopic treatment (n = 23), and lymphadenectomy (n = 9) was 47.4%, 70.9%, and 33.3%, respectively. CONCLUSIONS A quarter of patients developed recurrent disease, mostly locoregional, after complete response. Complete response patients with originally advanced stage disease had fair clinical outcomes; salvage treatments after locoregional recurrence achieved modest long-term survival.

Abstract
BACKGROUND Anastomotic leak is a potentially life-threatening complication following esophageal cancer surgery. In this study, we aimed to clarify the efficacy of endoscopic filling with polyglycolic acid (PGA) sheets and fibrin glue for anastomotic leak after esophageal cancer surgery. METHODS Consecutive patients who underwent endoscopic filling with PGA sheets and fibrin glue for anastomotic leak after esophageal cancer surgery between August 2014 and January 2020 were included in the study, with its efficacy retrospectively reviewed. We performed endoscopic filling using two methods: (1) filling the fistula with PGA sheets, followed by the application of a fibrinogen and thrombin solution (conventional method) and (2) filling the fistula with PGA sheets pre-soaked in a fibrinogen solution, followed by the application of a thrombin solution (pre-soak method). RESULTS A total of 14 patients underwent endoscopic filling procedures within the study period. The endoscopic filling procedures were successfully performed in all cases and no adverse events associated with the procedures were observed. Fistula closure was obtained in 10 (71%) cases. In the 10 successful cases, the median number of procedures was 1 (range 1-3) and the median time from the first procedure to oral intake was 7.5 days (range 4-36 days). The success rate of the pre-soak method was significantly higher than that of the conventional method (90% vs. 25%, P = 0.041). CONCLUSIONS Endoscopic filling with PGA sheets and fibrin glue is a safe and effective treatment for the closure of an anastomotic leak. The pre-soak method can achieve successful endoscopic filling.
