    The present study aimed to assess the feasibility of global standard chemoradiotherapy (CRT) followed by surgery in patients with esophageal cancer. A prospective study was conducted at Nagoya University Hospital (Nagoya, Japan) to evaluate global standard CRT followed by surgery in patients with esophageal cancer. The CRT regimen consisted of 75 mg/m2 cisplatin on day 1 and 1,000 mg/m2 fluorouracil daily on days 1-4 given twice 4 weeks apart together with concurrent esophageal irradiation starting on day 1 (group A). For comparison, 17 patients with esophageal cancer who had received the same chemotherapy regimen but with lower drug doses were retrospectively reviewed: 70 mg/m2 cisplatin on day 1 and 700 mg/m2 fluorouracil daily on days 1-4 given twice 4 weeks apart together with concurrent esophageal irradiation starting on day 1 (group B). Grade 3 or worse adverse events were observed in 9 of the 12 patients (75%) in group A and in 5 of the 17 patients (29%) in group B. The patients in group A were more likely to experience grade 3 or worse neutropenia (50%) than those in group B (6%). No febrile neutropenia or treatment-related deaths occurred in either group. A total of 11 patients (92%) in group A and 16 patients (94%) in group B subsequently underwent an esophagectomy, and 9 (82%) and 14 (88%) of these patients, respectively, achieved microscopically margin-negative resection (R0 resection). In conclusion, global standard CRT was more likely to cause severe but manageable adverse events. There was no apparent difference in the R0 resection rate or postoperative complications between the two treatments. This clinical trial was registered at the Japan Registry of Clinical Trials (trial registration number: jRCT1041180004) on September 11, 2018.

    BACKGROUND/AIM: In patients with esophageal cancer, muscle loss induced by neoadjuvant therapy before esophagectomy is correlated with poor prognosis. However, little is known about the causes of muscle loss. Thus, the purpose of this retrospective study was to clarify the risk factors for muscle loss during neoadjuvant therapy. PATIENTS AND METHODS: Patients with esophageal cancer who underwent neoadjuvant therapy before esophagectomy between 2009 and 2020 were investigated (n=132). The patients received either cisplatin plus 5-fluorouracil (CF); docetaxel, cisplatin plus 5-fluorouracil (DCF); or CF with radiotherapy as neoadjuvant therapy. The cross-sectional areas of the bilateral psoas muscles were measured at the level of the third lumbar vertebra using CT, before and after neoadjuvant therapy, and psoas muscle loss was calculated. The patients were divided into the high muscle loss group with 5% or more muscle loss or the low muscle loss group with less than 5% loss. Correlations between muscle loss and clinical factors were evaluated. RESULTS: The median value of psoas muscle loss was 5.30%. Psoas muscle loss was significantly correlated with a poor 3-year overall survival rate (p=0.034). Multivariate analysis showed that the independent factors associated with muscle loss were age ≥70 years [odds ratio (OR)=2.43, p=0.022], treatment with DCF (OR=3.47, p=0.034), and a poor response to neoadjuvant therapy (OR=2.68, p=0.028). CONCLUSION: A regimen of DCF was a major trigger of muscle loss during neoadjuvant therapy.

    BACKGROUND/AIM: α-Bisabolol is an essential oil component extracted from plants, such as chamomile. We have previously reported that α-bisabolol suppressed proliferation, invasion, and motility of pancreas cancer. Cyclodextrin improved the solubility of α-bisabolol, therefore it enabled to administer intravenously. The aim of this study was to clarify the effect of cyclodextrin conjugated α-bisabolol (CD-BSB) and the signals pathways associated with α-bisabolol for pancreatic cancer. MATERIALS AND METHODS: Human pancreatic cancer cell lines were treated with or without CD-BSB. Cytomorphology and apoptosis were assessed in these treated groups. In addition, several phosphorylated proteins were analyzed to clarify the signal pathway concerning CD-BSB. In subcutaneous xenograft model, tumor volume and Ki-67 expression were evaluated among Control (untreated), CD-BSB, or Gemcitabine (GEM). RESULTS: CD-BSB significantly changed cytomorphology and induced apoptosis in pancreatic cancer cells. CD-BSB suppressed phosphorylation of focal adhesion kinase (FAK). In addition, pFAK 397 was inhibited by CD-BSB in a concentration-dependent manner in cancer cells. In the subcutaneous xenograft models, the tumor volume in the CD-BSB groups was lower than Control groups. Ki67-positive cells in CD-BSB treated group were lower than the GEM-treated groups. CONCLUSION: We clarified the efficiency of CD-BSB in xenograft tumor using intravenous administration. α-Bisabolol suppresses phosphorylation of FAK 397 and impairs cytoskeletal polymerization in a pancreatic cancer cell line. Further investigations are required to reveal the precise mechanisms of the antitumor effects of solubilized α-bisabolol to facilitate its clinical application. Our data indicate that solubilized α-bisabolol has therapeutic potential and could improve the prognosis of cancer patients.

    Background/Aim: Deep ultraviolet (DUV) light spans within the 250 nm to 350 nm invisible wavelength range. Although it strongly damages various cells, the efficacy of DUV irradiation on pancreatic cancer cells has never been clarified. The purpose of this study was to reveal the antitumor effects of DUV irradiation on pancreatic cancer cells. Materials and Methods: Human pancreatic cancer cell lines were eradicated with DUV or ultraviolet A (UVA) for 5 s. Several angiogenesis-related proteins were studied in cancer cells after DUV irradiation using a protein antibody array. A subcutaneous xenograft model was established by inoculation of pancreatic cancer cells into mice. Tumors in this model were irradiated with DUV or UVA once or twice for two weeks. Tumor volumes in these groups (DUV×1: one irradiation, DUV×2: two irradiations, and untreated) were analyzed one week after the second irradiation. Results: DUV irradiation significantly changed the cytomorphology of pancreatic cancer cells. In addition, DUV irradiation induced apoptosis on pancreatic cancer cells more strongly than UVA irradiation and no irradiation. Interestingly, lower expression of thrombospondin 1 (TSP1) and tissue inhibitor of metalloproteinase 1 (TIMP1) was identified after DUV treatment. The tumor volume in the DUV-treated groups (DUV×1 and DUV×2) was smaller than that in the untreated group. Conclusion: Further investigations are required to reveal the precise mechanisms of the antitumor effects of DUV irradiation and to facilitate its clinical application as a new therapy for pancreatic cancer. Overall, DUV irradiation can be potentially used as a therapeutic option of pancreatic malignancy.

    Aims: The docetaxel and cisplatin plus 5-fluorouracil (5-FU) (DCF) regimen is expected to be superior to cisplatin plus 5-FU for the preoperative treatment of esophageal cancer. However, a high risk of adverse effects, including febrile neutropenia (FN), has been reported. To evaluate the effectiveness and safety of DCF with prophylactic pegfilgrastim, we conducted a phase II study. Methods: The regimen consisted of intravenous administration of docetaxel (70 mg/m2 per day) and cisplatin (70 mg/m2 per day) on day 1 and a continuous infusion of 5-FU (750 mg/m2 per day) on days 1–5. A single 3.6-mg dose of pegfilgrastim was given as a subcutaneous injection on day 7 of each cycle. This regimen was repeated every 3 weeks for a maximum of three cycles. The primary endpoint was the grade-2/3 histopathological response rate. Results: Thirty-seven eligible patients were enrolled and received DCF. Thirty-four patients underwent esophagectomy. Two patients received chemoradiotherapy or radiotherapy without surgery. One patient withdrew consent and ended his hospital visit. One patient received additional radiotherapy before surgery. Histopathological responses of grade 3, grade 2, grade 1b, and grade 1a were observed in two (5.4%), 14 (37.8%), 10 (27.0%), and seven (18.9%) patients, respectively, and the primary endpoint was met. Of the 37 eligible patients, 11 (29.7%) developed FN in the first cycle. Conclusions: Since the histopathological responses were as expected, DCF with prophylactic pegfilgrastim is considered to be effective as preoperative chemotherapy. However, the prophylactic use of pegfilgrastim on day 7 was insufficient to prevent FN.

    Late-onset postoperative pneumonia (LOPP) after esophagectomy is poorly understood. This study was designed to clarify the features and risk factors for this event. Patients who underwent esophagectomy for esophageal cancer between 2006 and 2016 were included. LOPP was defined as radiologically proven pneumonia that occurred over 3 months after surgery, and clinically relevant late-onset postoperative pneumonia (CR-LOPP) was defined as LOPP that required administration of oxygen and antibiotics in the hospital and/or more intensive treatment. The total psoas muscle area (TPA) was measured using preoperative and postoperative (at 3 months after surgery) computed tomography scan images. Potential risk factors for CR-LOPP were investigated. Among 175 study patients, 46 (26.3%) had LOPP, 29 (16.6%) of whom exhibited CR-LOPP with a cumulative incidence of 15.6% at 3 years and 22.4% at 5 years. Four (13.8%) of these patients died of LOPP. Univariable analysis showed that clinical stage ≥III (P = 0.005), preoperative prognostic nutritional index (PNI) <45 (P = 0.035), arrhythmia (P = 0.014), postoperative hospital stay ≥40 days (P = 0.003), and percent decrease of TPA more than 5% (P < 0.001) were associated with CR-LOPP but not early onset postoperative pneumonia. Multivariable analysis revealed that clinical stage ≥III (hazard ratio [HR] 3.01, P = 0.004), postoperative hospital stay ≥40 days (HR 2.51, P = 0.015), and percent decrease of TPA >5% (HR 9.93, P < 0.001) were independent risk factors for CR-LOPP. CR-LOPP occurred in over 20% of patients at 5 years, and early postoperative loss of TPA was a potential trigger for this delayed complication.

    Trefoil factor family 1 (TFF1) is one of three members of the trefoil factor family that are abundantly expressed in the gastrointestinal mucosal epithelium. Recent studies have shown that TFF1 acts as a tumor suppressor in gastric, pancreatic and hepatocellular carcinogenesis; however, little is known about its function in esophageal carcinogenesis, especially in esophageal adenocarcinoma (EAC). Barrett’s epithelium is the metaplastic columnar epithelium of the esophagus and a known premalignant lesion of EAC. To investigate the role of TFF1 in EAC development, a mouse model of Barrett’s epithelium was employed, and human specimens of EAC were assessed by immunohistochemistry (IHC) and methylation-specific PCR. Wild-type (WT) mice underwent gastrojejunostomy on the forestomach, resulting in the development of Barrett’s epithelium-like (BE-like) epithelium adjacent to the anastomotic site. BE-like epithelium in these mice expressed TFF1, indicating the association of TFF1 with esophageal adenocarcinoma. TFF1-knockout (TFF1KO) mice underwent the same procedure as well, revealing that a deficiency in TFF1 resulted in the development of adenocarcinoma in the anastomotic site, presumably from BE-like epithelium. IHC of human samples revealed strong TFF1 expression in Barrett’s epithelium, which was lost in some EACs, confirming the association between TFF1 and EAC development. Aberrant DNA hypermethylation in TFF1 promoter lesions was detected in TFF1-negative human EAC samples, further confirming not only the role of TFF1 in EAC but also the underlying mechanisms of TFF1 regulation. In addition, IHC revealed the nuclear translocation of β-catenin in human and mouse EAC, suggesting that activation of the Wnt/β-catenin pathway was induced by the loss of TFF1. In conclusion, these results indicate that TFF1 functions as a tumor suppressor to inhibit the development of esophageal carcinogenesis from Barrett’s epithelium.

    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.

    In Japan, esophagectomy after two courses of 5-fluorouracil plus cisplatin is regarded a standard strategy for treating resectable stage II or III esophageal squamous cell carcinoma (ESCC). However, 5-fluorouracil plus cisplatin does not benefit cohorts with clinical stage III ESCC, suggesting the requirement for a more effective regimen. We are conducting a single-arm phase II study to assess the safety and efficacy of neoadjuvant docetaxel, oxaliplatin plus S-1 (DOS) for treating patients with clinical stage III ESCC. The primary endpoint is the pathological response rate, and the target number is 45 patients. Safety, response rate, R0 resection rate, and survival are secondary endpoints. This trial is registered in the Japan Registry of Clinical Trials as jRCTs041210023. We are conducting a prospective phase II trial to evaluate the safety and efficacy of three courses of neoadjuvant DOS treatment followed by radical esophagectomy for clinical stage III ESCC.

    Anastomotic leakage after esophagectomy is associated with prolonged hospitalization and increased medical cost. Additionally, it sometimes leads to a fatal condition and impaired postoperative quality of life. During the process of wound healing, β-hydroxy-β-methylbutyrate (HMB) is important for collagen biosynthesis. An open-label prospective intervention trial has been designed to evaluate the treatment effect of an enteral nutrient containing HMB with arginine and glutamine (Abound, Abbott Japan Co., Ltd.) for leakage at the anastomotic site after esophagectomy. Patients in whom leakage at the anastomotic site developed within 14 days after esophagectomy are eligible and Abound (24 g) is administered for 14 days through an enteral feeding tube. The target sample size is 10. The primary endpoint is duration between diagnosis and cure of leakage. Surgical procedure, safety, length of fasting, drainage placement and hospital stay, and nutritional status are determined as secondary endpoints. A historical control consisting of 20 patients who had leakage at the anastomotic site after esophagectomy between 2005 and 2018 at Nagoya University Hospital is compared with enrolled patients.

    Purpose: The aim of this study was to evaluate the impact of cervical lymph node dissection on acid reflux and duodenogastroesophageal reflux (DGER) in patients undergoing transthoracic esophagectomy with gastric tube reconstruction and intrathoracic esophagogastrostomy. Methods: Thirty-one patients receiving transthoracic esophagectomy with gastric tube reconstruction by intrathoracic esophagogastrostomy were divided into the following two groups: a two-field lymph node dissection group (2F group) and a three-field lymph node dissection group (3F group). All patients underwent 24-h pH and bilirubin monitoring and gastrointestinal endoscopy at 1 year after surgery. The 24-h pH and bilirubin monitoring results, endoscopic findings, and reflux symptoms were compared between the 2 groups. Results: No acid reflux was observed in the 2F group, whereas it was observed in 6 (40%) patients in the 3F group (p = 0.007). DGER was found in 2 patients (13%) in the 2F group and in 8 (53%) in the 3F group (p = 0.023). Four patients (25%) in the 2F group and 9 (60%) in the 3F group (p = 0.048) had reflux esophagitis. Conclusion: Cervical lymph node dissection increases acid reflux and DGER and can lead to an increase in the incidence of reflux esophagitis in patients undergoing intrathoracic esophagogastrostomy.

    Background: The aim of this study was to evaluate the impact of the location of esophagogastrostomy on acid and duodenogastroesophageal reflux (DGER) in patients undergoing gastric tube reconstruction and intrathoracic esophagogastrostomy. Methods: Thirty patients receiving transthoracic esophagectomy without cervical lymph node dissection and gastric tube reconstruction by intrathoracic anastomosis were enrolled. All patients underwent 24-h pH and bilirubin monitoring and gastrointestinal endoscopy one year after surgery. Patients were divided into three groups according to esophagogastrostomy location: group A (n = 9), above the top of the aortic arch; group B (n = 15), between the top and bottom of the aortic arch; and group C (n = 6), below the bottom of the aortic arch. The relations among the esophagogastrostomy location, 24-h pH and bilirubin monitoring results, endoscopic findings, and reflux symptoms were investigated. Results: No acid reflux into the remnant esophagus was observed in group A, whereas it was observed in three of 15 patients (20%) in group B and in two of six patients (33%) in group C (P = 0.139). No DGER was found in group A, whereas DGER was observed in eight (53%) patients in group B and all patients in group C (P < 0.001). Reflux esophagitis was observed in one patient (11%) in group A, five patients (33%) in group B, and all patients in group C (P = 0.002). Conclusion: In gastric tube reconstruction via intrathoracic anastomosis, esophagogastrostomy should be performed above the top of the aortic arch to prevent postoperative DGER and reduce the incidence of reflux esophagitis.

    Background: The aim of this study is to evaluate the clinical value of a prophylactic minitracheostomy (PMT) in patients undergoing an esophagectomy for esophageal cancer and to clarify the indications for a PMT. Methods: Ninety-four patients who underwent right transthoracic esophagectomy for esophageal cancer between January 2009 and December 2013 were studied. Short surgical outcomes were retrospectively compared between 30 patients at high risk for postoperative pulmonary complications who underwent a PMT (PMT group) and 64 patients at standard risk without a PMT (non-PMT group). Furthermore, 12 patients who required a delayed minitracheostomy (DMT) due to postoperative sputum retention were reviewed in detail, and risk factors related to a DMT were also analyzed to assess the indications for a PMT. Results: Preoperative pulmonary function was lower in the PMT group than in the non-PMT group: FEV1.0 (2.41 vs. 2.68 L, p = 0.035), and the proportion of patients with FEV1.0% <60 (13.3% vs. 0%, p = 0.009). No between-group differences were observed in the proportion of patients who suffered from postoperative pneumonia, atelectasis, or re-intubation due to respiratory failure. Of the 12 patients with a DMT, 11 developed postoperative pneumonia, and three required re-intubation due to severe pneumonia. Multivariate analysis revealed FEV1.0% <70% and vocal cord palsy were independent risk factors related to a DMT. Conclusion: A PMT for high-risk patients may prevent an increase in the incidence of postoperative pneumonia and re-intubation. The PMT indications should be expanded for patients with vocal cord palsy or mild obstructive respiratory disturbances.

    Background: Upper extremity deep vein thrombosis (UEDVT) is a rare but important complication because it can cause pulmonary embolism. The aim of this study was to investigate the incidence of UEDVT after esophagectomy and the risk factors related to UEDVT. Methods: This study included 88 patients who underwent esophagectomy with retrosternal or posterior mediastinal reconstruction using gastric tube. The incidence of UEDVT and the diameter of left brachiocephalic vein were measured using postoperative contrast-enhanced computed tomography (CT). (a) The distance from sternum to brachiocephalic artery and (b) the distance from sternum to vertebra were measured by preoperative CT, and the ratio of (a) to (b) was defined as the width of the retrosternal space. Results: Among the patients, 14 (15.9%) suffered from UEDVT. All UEDVTs were found in left-side upper extremity deep veins. Twelve of the 14 patients (85.7%) underwent retrosternal reconstruction. In a multivariate analysis, retrosternal reconstruction was an independent risk factor for UEDVT (odds ratio 5.48). The diameter of the left brachiocephalic vein in patients with retrosternal reconstruction was significantly smaller than that in patients with posterior mediastinal reconstruction (4.3 vs 6.9 mm; P < 0.001) due to compression of left brachiocephalic vein by the gastric tube. Among patients with retrosternal reconstruction, the width of the retrosternal space in patients with UEDVT was significantly smaller than that in patients without UEDVT (0.21 vs 0.27; P = 0.001). Conclusion: Retrosternal reconstruction can be a risk factor for UEDVT. In patients with small width of the retrosternal space, retrosternal reconstruction might be inappropriate.

    A 71-year-old woman with dysphagia was diagnosed with thoracic esophageal squamous cell carcinoma by endoscopic biopsy at another hospital. She had previously undergone partial breast excision with axillary lymph node dissection for right breast cancer eleven years earlier and subtotal stomach-preserving pancreatoduodenectomy with Child's reconstruction for ampullary cancer ten years earlier. Gastrointestinal endoscopy showed a stricture due to a bulging submucosal tumor in the mid-thoracic esophagus. The tumor was diagnosed as an esophageal metastasis from breast cancer by endoscopic ultrasound-guided fine-needle aspiration biopsy. After six courses of fulvestrant, the tumor progressed, completely impeding her ability to swallow. An esophagectomy was planned in a one-stage operation because of the expectation of a prolonged survival and her strong hope of regaining oral intake. Unfortunately, she underwent emergent omental patch repair for perforation of the gastrojejunostomy site due to an anastomotic ulcer one day before the scheduled operation. Due to postoperative impairment of her performance status, she subsequently underwent a two-stage esophageal operation. In the first surgical stage, prone position thoracoscopic esophagectomy and cervical esophagostomy were performed and she was discharged with enteral nutrition on postoperative day 15. Sixty-one days after the first surgical stage, esophageal reconstruction was performed using a pedicled jejunum with microvascular anastomosis via the subcutaneous route. She was discharged without any complications 20 days after the second operation.

    A 52-year-old man with a cough, high fever, and inappetence was diagnosed with thoracic empyema on computed tomography at a local hospital. He had undergone continuous thoracic drainage for a spontaneous esophageal rupture that occurred 17 years earlier. He developed left thoracic empyema 2, 14 and 17 years following the initial esophageal rupture that improved with conservative therapy each time. The most recent episode of thoracic empyema also resolved with conservative therapy. However, he was referred to our hospital for further examination and more complete surgical treatment for recurrent thoracic empyema. Gastrointestinal endoscopy showed a scar from the previous esophageal rupture in the lower esophagus. We considered that recurrent esophageal rupture may have caused repeated episodes of thoracic empyema based on endoscopic findings and his past history and elected to perform subtotal esophagectomy to provide a complete cure. A left transthoracic esophagectomy with a left lower lung lobectomy and gastric tube reconstruction via a retrosternal route were performed. A latissimus dorsi muscle flap was used to eliminate the dead space after lower lung lobectomy to prevent recurrent thoracic empyema. The bronchial stump was covered with a pedicled intercostal muscle flap to prevent leakage from the stump. Minor leakage from the esophagogastrostomy site developed during the postoperative course but resolved with conservative therapy. The patient was transferred to the previous hospital on the 36th postoperative day. Four years after surgery, he had good oral intake and nutritional status without any evidence of recurrent thoracic empyema.

    深紫外線照射は、癌細胞株において細胞形態を変化させ、アポトーシスを誘導した。作用機序としてCHK1、TLK1、MRE11が関与しており、TLK1 およびMRE11の抑制により、深紫外線照射によるアポトーシス誘導能が増強した。担癌動物モデルにおいて、深紫外線照射は腫瘍の増殖を抑制した。TLK1阻害剤の投与は、深紫外線照射による抗腫瘍効果を増強させ、腫瘍におけるKi67の発現は低下していた。ブタの胃粘膜に対して、照射により生じた粘膜面の欠損は、1週間後は治癒していた病理学的検査、血液生化学検査において異常を認めなかった。臨床応用のために更なる研究は必要であるが、新規治療法開発の可能性が示唆された。
    深紫外線によるアポトーシスの作用機序に関連するシグナルを明らかにした。またDNA修復遺伝子の抑制により深紫外線の抗腫瘍効果の増強が可能であることを明らかにした。これらは深紫外線による細胞障害作用を癌治療に応用するための重要な知見であり学術的意義が大きい。また本研究により新規治療法開発の可能性が示唆され、深紫外線による治療法が可能になれば、生存率を含めた治療成績の向上が期待され社会的意義は大きい。
