Abstract
BACKGROUND For resectable esophageal cancer (EC), it remains controversial whether to place percutaneous endoscopic gastrostomy (PEG) before the curative surgery to provide nutritional support during the neoadjuvant therapy. OBJECTIVE To compare surgical outcomes for patients who received preoperative PEG and those without PEG placement (No-PEG) insertion prior to surgery in a potentially operable EC. METHODS A comprehensive literature search was conducted to identify randomized and non-randomized studies comparing PEG and No-PEG groups. RESULTS Four retrospective studies with a total number of 1,027 patients were identified and included in this meta-analysis. The differences in anastomotic leakage, anastomotic stricture, morbidity, pulmonary complications, wound infection, and hospital stay were not statistically significant between the two groups. Operation time was significantly shorter in the PEG group. There was no PEG-related gastric conduit failure and no leak from the PEG site in the PEG group. CONCLUSION We conclude preoperative PEG for resectable EC is a safe procedure with no adverse effect on the gastric tube construction and anastomosis, it can be selectively inserted for EC patients with marked weight loss and malnutrition or those at risk of developing malnutrition during neoadjuvant therapy.

Abstract
BACKGROUND/AIM: Surgical stress significantly decreases serum diamine oxidase (DAO), a marker of intestinal mucosal maturation and integrity. This study aimed to determine the effects of postoperative enteral and total parenteral nutrition (EN and TPN, respectively) in patients with esophageal cancer. PATIENTS AND METHODS This prospective randomized trial compared serum DAO activities, nutritional states, trace elements and complications between patients who underwent esophagectomy and received EN or TPN for seven days thereafter. RESULTS Fifty-one patients were randomized to receive EN or TPN. The rates of change in serum DAO activity from the day before surgery were 0.79, 0.89 and 0.91 on postoperative days (POD) 1, 3 and 7, respectively, in the EN group, and 0.64, 0.76 and 1.06, respectively, in the TPN group, with no significant differences. Furthermore, the rates of changes in indicators of nutritional status, namely total protein, albumin, total cholesterol, trace element concentrations and infectious and non-infectious complications did not significantly differ between the groups. CONCLUSION EN and/or TPN can be administered for early nutritional management until resumption of oral intake after esophagectomy according to the postoperative status of individual patients with esophageal cancer.

Abstract
3D patient-derived organoids (PDOs) have been utilized to evaluate potential therapies for patients with different cancers. However, the use of PDOs created from treatment-naive patient biopsies for prediction of clinical outcomes in patients with esophageal cancer has not yet been reported. Herein we describe a pilot prospective observational study with the goal of determining whether esophageal cancer PDOs created from treatment naive patients can model or predict clinical outcomes. Endoscopic biopsies of treatment-naive patients at a single tertiary care center were used to generate esophageal cancer PDOs, which were treated with standard-of-care chemotherapy, gamma-irradiation, and newer non-standard approaches, such as proton beam therapy or two small molecule inhibitors. Clinical outcomes of patients following neoadjuvant treatment were compared to their in vitro PDO responses, demonstrating the PDO's ability to mirror clinical response, suggesting the value of PDOs in prediction of clinical response to new therapeutic approaches. Future prospective clinical trials should test the use of pre-treatment PDOs to identify specific, targeted therapies for individual patients with esophageal adenocarcinoma.

Abstract
AIM: To evaluate whether a novel irradiation stent (NIS) could decrease the rate of recurrent dysphagia, compared to the conventional irradiation stent (CIS) in patients with malignant dysphagia. MATERIALS AND METHODS We performed an open-label randomized controlled trial of participants with malignant dysphagia. A total of 94 participants were parallelly allocated into the NIS group or the NIS group between April 2019 and April 2020. The primary endpoint was the rate of recurrent dysphagia. The secondary endpoints included technical success, clinical success, overall survival, and adverse events. RESULTS The technical success rate and the clinical success rate was 100.0% (47/47) in both groups. The median follow-up period was 189 days (range 14-422 days). Recurrent dysphagia was observed in 12.8% (6/47) of patients in the NIS group and 31.9% (15/47) in the CIS group (P = 0.026). Tissue/tumor growth occurred in 4 patients (8.5%) after NIS placement and 12 (25.5%) after CIS placement (P = 0.028). Stent migration occurred in 2 patients (4.3%) after NIS placement and 3 (6.4%) after CIS placement (P = 0.646). No food obstruction was found in both groups. The median overall survival was 177 days (95% confidence interval [CI] 139-214) in the NIS group and 168 days (95% CI 153-183) in the CIS group (P = 0.932). The incidence of severe adverse events was comparable between the two groups (21.3% vs. 17.0%, P = 0.600). CONCLUSIONS In patients with malignant dysphagia, compared with CIS, NIS could decrease the rate of tissue/tumor growth without increase the rate of stent migration and therefore decrease the rate of recurrent dysphagia.

Abstract
INTRODUCTION Epidemiological studies assessing relative risk and incidence rate of esophageal cancer in patients with achalasia are scarce. We performed a long-term prospective cohort study to evaluate the risk of both squamous cell carcinoma and adenocarcinoma of the esophagus in these patients. METHODS Between 1973 and 2018, patients with primary achalasia were followed by the same protocol including upper endoscopy with esophageal biopsies. Standardized incidence ratios (SIRs) with 95% confidence interval (CI) were used to estimate the relative risk of esophageal cancer in patients with achalasia compared with the sex- and age-matched general population. RESULTS A cohort of 566 patients with achalasia (46% men, mean age at diagnosis: 48.1 years) was followed for a mean of 15.5 years since the diagnosis of achalasia. Overall, 20 patients (15 men) developed esophageal cancer: 15 squamous cell carcinoma and 5 adenocarcinoma. The risk of esophageal cancer was significantly greater than the general population (SIR 104.2, 95% CI 63.7-161), and this for both squamous cell carcinoma (SIR 126.9, 95% CI 71.0-209.3) and adenocarcinoma (SIR 110.2, 95% CI 35.8-257.2). The excess risk was higher in men than women. Annual incidence rate of esophageal cancer was only 0.24% and was higher for squamous cell carcinoma (0.18%) than adenocarcinoma (0.06%). DISCUSSION Patients with achalasia have an excess risk of developing both squamous cell carcinoma and adenocarcinoma of the esophagus; however, this prospective cohort study confirms that the annual incidence of esophageal cancer is rather low. These findings may have implications for endoscopic surveillance of patients with achalasia.

Abstract
BACKGROUND & AIMS To elucidate the impact of synbiotics on bacterial translocation and subsequent bacteremia during neoadjuvant chemotherapy for esophageal cancer. METHODS Patients requiring neoadjuvant chemotherapy for esophageal cancer were randomized to receive synbiotics (synbiotics group) or no synbiotics (control group) during chemotherapy. Blood and fecal samples were taken before and after every chemotherapy cycle, and 1 day before surgery. Mesenteric lymph nodes (MLNs) were harvested at laparotomy (MLN-1) and after resection of the tumor (MLN-2). Bacteria in each sample were detected. Fecal microbiota and organic acid concentrations were also determined. The primary endpoint was the detection of bacteria in the blood samples, as well as the incidence of side effects during chemotherapy. The secondary endpoint was the detection rate of bacteria in the MLN samples collected during surgery. RESULTS The study recruited a total of 42 patients (22 in the control group, 20 in the synbiotics group). Bacteria were detected in 16 of 101 blood samples in the control group, whereas those were detected only 2 of 100 blood samples in the synbiotics group (p < 0.001) during neoadjuvant chemotherapy. Additionally, bacteria were detected in 12 of 34 MLN samples in the control group, whereas no bacteria were detected in 38 MLN samples in the synbiotics group (p < 0.001). Suppression of bacterial translocation was at least partly associated with an increased fecal acetic acid concentration as well as a lowered fecal pH by synbiotics. The incidence rate of grade 3 gastrointestinal toxicity during chemotherapy was lower in the synbiotics group compared to the control group (8/22 vs. 1/20, p = 0.022). CONCLUSIONS Neoadjuvant chemotherapy for esophageal cancer may induce bacterial translocation and subsequent bacteremia, which can be prevented by synbiotics administration.

Annals of surgery. 2020;(1):48-54
Abstract
OBJECTIVE This prospective randomized phase-II trial examined whether gastric reconstruction with duodenal diversion plus Roux-en-Y anastomosis(RY) minimized gastroduodenal reflux and delayed gastric emptying compared with standard gastric reconstruction. SUMMARY BACKGROUND DATA There is no established standard surgical procedure to prevent both gastroduodenal reflux and delayed gastric emptying simultaneously. METHODS Sixty patients with thoracic esophageal cancer scheduled to undergo esophagectomy with retrosternal gastric tube reconstruction were randomly allocated to standard gastric reconstruction (non-RY, n = 31) or gastric reconstruction with duodenal diversion plus RY (n = 29) groups. Primary endpoint was quality of life assessed by DAUGS-32 score 1 year after surgery. Secondary endpoints were the extent of postoperative duodenal juice reflux into the gastric tube, postoperative morbidity, endoscopic findings, body weight changes, and nutritional status. RESULTS Preoperative clinicopathological characteristics and postoperative morbidity did not differ significantly between groups. However, operation time and blood loss volume were significantly higher in the RY group. Pancreatic amylase concentrations in the gastric conduit on postoperative days 2, 3, and 7 were higher in the non-RY group. Postoperative endoscopic examination showed residual gastric content in 7 of 17 patients in the non-RY group but in none in the RY group (P = 0.012). Quality of life was significantly favorable in the RY group with regard to reflux symptoms and food passage dysfunction. Postoperative body weight changes, serum albumin levels, and peripheral blood lymphocyte counts were not significantly different between groups. CONCLUSION Gastric reconstruction with duodenal diversion plus RY is effective in improving both gastroduodenal reflux and delayed gastric emptying.

Feasibility, safety and outcome of endoscopic gastrostomy in patients with esophageal cancer.
Laranjo, A, Brito, M, Nunes, G, Santos, CA, Fonseca, J
Nutricion hospitalaria. 2020;(4):660-666
Abstract
Background and aims: esophageal cancer (EC) is an important health problem worldwide with high morbidity and mortality. EC patients are likely to develop malnutrition. The aim of this study was to assess the feasibility and safety of endoscopic gastrostomy (PEG) feeding in EC cancer, and to identify risk factors associated with poor prognosis. Methods: a retrospective observational study was performed using records from EC patients referred for PEG. Age, gender, cancer histologic subtype, indication for gastrostomy, and mortality data were recorded. NRS 2002, body mass index (BMI), hemoglobin, serum albumin, transferrin and total cholesterol were collected at the day of PEG. An association between anthropometric, clinical and laboratorial data with patient survival was assessed. Results: data were obtained for forty-one EC patients (36 men and 5 women) aged 39-88 years (mean, 62 years). Gastrostomy was possible in all patients referred to PEG (27 patients selected for curative treatment and 14 patients for palliative nutrition). No major complications occurred. Mean survival after PEG was 18.1 months, and mortality rate at 3 months was 31.7 %. Most patients (34; 82.9 %) died under PEG feeding. Mean BMI was 21.3 kg/m2 and 14 patients (34.1 %) patients had low BMI. Serum albumin, transferrin and total cholesterol were low in 10 (24.4 %), 20 (48.8 %) and 18 (43.9 %) patients, respectively. Higher BMI (R = 0.30), serum albumin (R = 0.41) and transferrin (R = 0.47) tended to be positively correlated with survival (p < 0.005). Conclusions: PEG is a feasible and safe technique for enteral feeding in EC patients. Higher BMI, serum albumin and transferrin levels at admission predict a better outcome. Enteral feeding through PEG should be considered early in EC patients due to their higher risk of malnutrition, which is associated with shorter survival.

Surgical Adjuncts During Esophagectomy.
Watkins, AA, Kent, MS, Wilson, JL
Thoracic surgery clinics. 2020;(3):315-320
Abstract
Esophagectomy is a major operation whereby intraoperative technique and postoperative care must be optimal. Even in expert hands, the complication rate is as high as 59%. Here the authors discuss the role of surgical adjuncts, including enteral access, nasogastric decompression, pyloric drainage procedures, and anastomotic buttressing as adjuncts to esophagectomy and whether they reduce perioperative complications.

Nivolumab in Combination with Irinotecan and 5-Fluorouracil (FOLFIRI) for Refractory Advanced Gastroesophageal Cancer.
Rogers, JE, Xiao, L, Trail, A, Blum Murphy, M, Palmer, M, Ajani, JA
Oncology. 2020;(5):289-294
Abstract
INTRODUCTION Advanced unresectable gastroesophageal cancers continue to confer a dismal patient prognosis. Limited options remain once the cancer is refractory to cytotoxics/biologics (like irinotecan, taxane, and ramucirumab). Recently, anti-programmed death-1 (anti-PD-1) inhibitors have been used with limited efficacy in select patients with adenocarcinoma. Similarly, irinotecan-based therapy has marginal efficacy. We combined irinotecan plus a fluoropyrimidine with an anti-PD-1 antibody, nivolumab, with hopes of having a higher advantage for patients. OBJECTIVES Primary objective was to assess safety judged by toxicities, dose delays, or dose reductions. Secondary endpoints included the assessment of response, overall survival (OS), and progression-free survival (PFS). METHODS We treated 15 patients with this combination during July 2017 to April 2019. Patients were included if they had follow-up at our institution. RESULTS Median doses given were nivolumab 240 mg + irinotecan 120 mg/m2 + 5-FU 2,000 mg/m2 over 46-48 h (or capecitabine 1,250 mg/m2/day; 7 days on, 7 days off) given every 2 weeks. Median age of the patients was 55 years, and all patients had an ECOG performance status of 0-1. The patients had a median of 1 prior therapy. Slightly over half of the patients had PD-L1 expression. The median number of cycles was 7. Five patients (33%) had a dose delay or dose adjustment. The most common reason for dose delay or adjustment was grade 2 fatigue. Disease control (response or stability) on first scan was 73.3% (n = 11). Median PFS and OS for the entire group was 7 and 13.3 months, respectively. CONCLUSION In this small cohort of patients, we conclude that this combination is quite feasible and resulted in prolonged stability in some patients. Further development of this regimen is warranted.
