Background: Laparoscopic and endoscopic cooperative surgery (LECS) technique for gastric submucosal tumor (SMT) has developed, but treatment of SMT on the esophagogastric junction (EGJ) remains technically difficult because excessive resection may result in postoperative transformation of the EGJ and cause stenosis, and intervention to lower esophageal sphincter may result in gastroesophageal reflux. The study aim was to evaluate the feasibility and safety of LECS for SMT on the EGJ. Methods: Between September 2012 and December 2018, LECS was performed for 21 patients with SMTs on the EGJ. Fundoplication was performed after LECS according to the intraoperative findings for each case. The patients’ backgrounds, operative outcomes, and follow-up data, including endoscopic findings of gastroesophageal reflux disease (GERD) and proton pomp inhibitor (PPI) use, were reviewed. Results: In all 21 cases, LECS was completed with a mean operation time of 225 min, and a mean blood loss of 8.8 mL. All patients were alive without recurrence within the mean follow-up period of 30.5 months. Both GERD and PPI use tended to be less frequent when fundoplication was performed, although these differences were not statistically significant. (7.7% vs. 37.5%; P = 0.091, 23.1% vs. 50.0%; P = 0.204, respectively). Conclusions: We demonstrated the feasibility and safety of LECS for SMTs even on the EGJ. Fundoplication after LECS may be an approach for the prevention of postoperative reflux esophagitis. Future research is warranted to validate the efficacy of the addition of fundoplication.Gastric Cancer, Nov. 2020, Gastric Cancer, 23(6) (6), 1084 - 1090, English, Domestic magazineScientific journal
- © 2020, The Japan Esophageal Society. Background: Presepsin is suggested to be an accurate sepsis diagnostic biomarker, playing an important role in distinguishing infection from no-infection status. However, to date, there is no study determining presepsin’s role in diagnosing post-esophagectomy infectious complications. Methods: Thirty patients who underwent esophagectomy for esophageal carcinoma were included in this prospective observational study. We investigated preoperative presepsin levels’ changes and evaluated the relationship between infectious complications and presepsin levels. Moreover, we analyzed the classification and regression tree (CART) to determine presepsin’s optimal cutoff values for discriminating infectious complications. Results: For 10 patients with infectious complications, median presepsin levels were 168, 337, 303, 271, 314, 978, and 752 pg/ml, pre- and immediately post-surgery, and 1, 2, 3, 5, 7 days post-surgery, respectively. Presepsin levels were significantly higher in the infectious complication group exclusively from preoperation to POD 7 (p = 0.048). Furthermore, area under the curve’s value of presepsin on POD 5 and 7 was higher than the other three biomarkers included for discriminating infectious complications (i.e., procalcitonin, leukocyte, and C-reacted protein). We set an optimal cutoff value for presepsin calculated by CART. Specifically, on POD 5, the cutoff was 888 pg/ml with a sensitivity of 60% and a specificity of 90%, and on POD 7, the cutoff was 668 pg/ml with a sensitivity of 60% and a specificity of 85%. Conclusions: Presepsin levels on POD 5 and 7 after esophagectomy are a valuable indicator of infectious complication’s detection vs. leukocyte, C-reacted protein, and procalcitonin.Esophagus, Oct. 2020, Esophagus, 17(4) (4), 399 - 407, English, Domestic magazineScientific journal
- © 2019 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd. We report the case of a 70-year-old woman with synchronous advanced esophageal cancer and pancreatic head cancer. To reduce the surgical invasiveness, we performed a two-stage operation that included percutaneous endoscopic gastrostomy and minimally invasive esophagectomy. In the first stage, we performed a percutaneous endoscopic gastrostomy, a thoracoscopic esophagectomy with cervical and mediastinal lymph node dissection, and an esophagostomy without a laparotomy. The second stage, which was performed 28 days after the first operation, consisted of a total gastrectomy, pancreaticoduodenectomy, colonic reconstruction, and jejunostomy. Fifty days after the second operation, the patient was discharged from the hospital. A two-stage operation that includes minimally invasive esophagectomy seems to be useful for avoiding serious postoperative complications, even in patients with rare, synchronous advanced cancers of the esophagus and the pancreatic head.Asian journal of endoscopic surgery, Jul. 2020, Asian journal of endoscopic surgery, 13(3) (3), 410 - 414, English, Domestic magazine

- © 2019, The International Gastric Cancer Association and The Japanese Gastric Cancer Association. Background: To safely perform minimized gastrectomy based on sentinel node (SN) concept for early gastric cancer patients, intraoperative diagnostic accuracy is indispensable. This study aimed to evaluate the clinical utility of the one-step nucleic acid amplification (OSNA) assay in the intraoperative diagnosis of SN metastasis in early gastric cancer patients compared with that of histopathological examination. Methods: We conducted a prospective study using the OSNA assay for 43 patients with cT1N0M0 gastric cancer undergoing gastrectomy with SN mapping. All the SNs and selected non-SNs were examined by routine histopathological diagnosis, and the OSNA assay. Results: We performed permanent histopathology (PH) in 1732 lymph nodes (LNs) (286 SNs and 1446 non-SNs) obtained from 43 patients. We also evaluated 439 LNs (286 SNs and 153 non-SNs) with the OSNA assay in addition to PH. Intraoperative histopathology (IH) was performed in 214 LNs (213 SNs and 1 non-SN). PH revealed LN metastasis in 6 patients (14%), all of whom showed positive SNs by PH. The diagnostic accuracy to predict the LN status based on the SN concept by histological examination was 100%. The concordance rate between the OSNA assay and the PH and IH were 0.970 and 0.981 respectively. Discordant results between PH and OSNA assay were observed in 13 LNs. The sensitivity and specificity of the OSNA assay compared with those of PH were 0.636, and 0.988, and compared with those of IH were 0.800, and 0.995. Conclusion: Our results suggest that the OSNA assay is a useful and convenient tool for the intraoperative detection of SN metastasis in early gastric cancer patients.Gastric Cancer, May 2020, Gastric Cancer, 23(3) (3), 418 - 425, English, Domestic magazineScientific journal
- © 2020 BJS Society Ltd Published by John Wiley & Sons Ltd Background: Oesophageal squamous cell carcinoma is an aggressive disease owing to early and widespread lymph node metastases. Multimodal therapy and radical surgery may improve prognosis. Few studies have investigated the efficacy of radical lymph node and thoracic duct resection. Methods: Patients with oesophageal squamous cell carcinoma who underwent transthoracic minimally invasive oesophagectomy (TMIE) for cancer at Keio University Hospital between January 2004 and December 2016 were selected. Between 2004 and 2008, TMIE was performed in the lateral decubitus position without thoracic duct resection (standard TMIE). From 2009 onwards, TMIE with extended lymph node and thoracic duct resection was introduced (extended TMIE). Demographics, co-morbidity, number of retrieved lymph nodes, pathology, postoperative complications and recurrence-free survival (RFS) were compared between groups. Results: Forty-four patients underwent standard TMIE and 191 extended TMIE. There were no significant differences in clinical and pathological tumour stage or postoperative complications. The extended-TMIE group had more lymph nodes removed at nodal stations 106recL and 112. Among patients with cT1 N0 disease, RFS was better in the extended-TMIE group (P < 0·001), whereas there was no difference in RFS between groups in patients with advanced disease. Conclusion: Extended TMIE including thoracic duct resection increased the number of lymph nodes retrieved and was associated with improved survival in patients with cT1 N0 oesophageal squamous cell carcinoma.British Journal of Surgery, May 2020, British Journal of Surgery, 107(6) (6), 705 - 711, English, International magazineScientific journal
- © 2019, The International Gastric Cancer Association and The Japanese Gastric Cancer Association. Background: Even though indications for endoscopic resection (ER) in early gastric cancer are determined based on the potential risk of lymph node metastasis, the criteria for ER remain controversial. Sentinel node (SN) mapping for early gastric cancer can help determine regional lymphatic flow patterns. The aim of this study was to assess lymphatic flow according to the SN concept in patients with early gastric cancer, especially those who satisfy the expanded criteria for ER. Methods: We retrospectively enrolled 301 patients diagnosed with pT1 adenocarcinoma who had undergone gastrectomy with SN mapping and had no lymphovascular invasion. Patients were categorized into six groups based on oncological assessment. We analyzed lymphatic flow, including the number of identified SN and SN basin, and the rate of SN metastasis in each group. Results: Of the 301 patients, 128 (42.5%) met the criteria for ER, with 18 in the absolute group and 110 in the expanded group; 173 (57.5%) were assigned to the surgical group. SN metastasis rate tended to be higher in surgical group patients than in ER criteria patients. In the expanded criteria group, the sub-group of patients with intramucosal, undifferentiated adenocarcinoma measuring 20 mm or less had a significantly greater number of identified SNs (p = 0.013) and SN basins (p = 0.032). Furthermore, SN metastasis was observed only in this group. Conclusions: Patients with intramucosal, nonulcerated, undifferentiated adenocarcinoma measuring 20 mm or less could develop a lymphatic network. For these patients, careful follow-up is required after ER.Gastric Cancer, May 2020, Gastric Cancer, 23(3) (3), 531 - 539, English, Domestic magazineScientific journal

- © 2020, Society of Surgical Oncology. Purpose: To arrange multidisciplinary treatment for esophageal cancer, a simple and accurate predictive marker for prognosis is required. The current multicenter prospective study aims to validate the prognostic significance of fibrinogen and albumin score (FA score) for esophageal cancer patients. Patients and Methods: Patients who were planned to undergo surgical resection for esophageal cancer at four participating institutions were enrolled in this study. Patient background, clinicopathological factors, and blood concentration of plasma fibrinogen and albumin were collected. Patients with elevated fibrinogen and decreased albumin levels were allocated a score of 2; those with only one of these abnormalities were allocated a score of 1; and those with neither of these abnormalities were allocated a score of 0. Recurrence-free survival (RFS) and overall survival (OS) were evaluated as a primary endpoint. Results: From four participating institutions, 133 patients were registered for the current analysis. The distribution of FA score of 0/1/2 was 84 (63%)/34 (26%)/15 (11%), respectively. In the analysis of primary endpoint, the preoperative FA score significantly classified RFS (FA score 1/2: HR 2.546, p = 0.013/6.989, p < 0.001) and OS (FA score 1/2: HR 2.756, p = 0.010/6.970, p < 0.001). We further evaluated the prognostic significance of FA score under stratification by pStage. As a result, with increasing FA score, RFS and OS were significantly worse in both pStage 0–I and II–IV groups. Conclusions: The prognostic impact of preoperative FA score was confirmed for esophageal cancer patients in the current multicenter prospective trial. FA score can be considered to predict postoperative survival and rearrange the treatment strategy before esophagectomy.Annals of Surgical Oncology, 2020, Annals of Surgical Oncology, 28(2) (2), 774 - 784Scientific journal
- © 2020 Kento Takaya et al. Introduction. We report a case of diastasis rectus abdominis (DRA), in which the improvement of the appearance was obtained by performing extra skin resection. Case Report. A 30-year-old woman presented persistent abdominal bulging after her second delivery. She was diagnosed as DRA by computed tomography. We underwent a surgery that tacking the anterior layer of the rectus sheath and resecting excess skin. Results. There has been no clinical evidence of recurrence, and the patient satisfies her abdominal appearance. Conclusion. Because DRA is not a true hernia, surgery for DRA should be performed in understanding how patients want to improve their aesthetic appearance.Case Reports in Medicine, 2020, Case Reports in Medicine, 2020, 7635801 - 7635801, English, International magazine
- © 2019, The Japan Esophageal Society. Background: Esophagectomy is associated with a high risk of postoperative complications, and the respiratory complications are the most common. Therefore, stratification of patients based on preoperative risk factors is essential. This study aimed to identify the risk of postoperative pneumonia (POP) based on the preoperative factors and determine the optimal perioperative surgical management strategy. Methods: This retrospective study involved 207 patients who underwent esophagectomy. The patients were divided into two groups, namely, with POP and without POP. To identify the risk factors for POP, the pre- and perioperative characteristics were analyzed. A receiver operating characteristics curve was used to determine a cutoff value of 2.40 L for the forced expiratory volume in 1 s (FEV1.0) and the cohort was divided into a high- and low-FEV1.0 group. A second analysis was then performed to determine the optimal surgical management for patients at a high risk for POP. Results: POP occurred in 45 (21.7%) patients. A multiple logistic regression analysis showed that FEV1.0 was significantly lower in the POP (+) group (P = 0.020); thus, a low FEV1.0 was found to be a risk factor for POP. Multiple logistic regression analysis showed that open thoracotomy was a significant risk factor for POP in low FEV1.0 patients (P = 0.013). Conclusions: A low FEV1.0 and an open thoracotomy are risk factors for POP. Therefore, patients with low FEV1.0 should be managed carefully and video-assisted thoracic surgery should be considered.Esophagus, Jan. 2020, Esophagus, 17(1) (1), 50 - 58, English, Domestic magazineScientific journal
- © 2019 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd. In Japan, the first endoscopic surgery, a laparoscopic cholecystectomy, was performed in 1990. Since then, operative procedures have been standardized, and the safety and efficacy of endoscopic surgery have been evaluated. In accordance with the social acceptance of endoscopic surgery as a less invasive type of surgery, the number of endoscopic procedures performed has increased in all surgical domains. The Japan Society for Endoscopic Surgery (JSES) has played an important role in the development of endoscopic surgery in Japan. Notably, a technical skills certification system for surgeons was established by the JSES to train instructors on how to teach safe endoscopic surgery. Furthermore, the JSES has conducted a national survey every two years to evaluate the status of endoscopic surgery over time. In 2017, 248 743 patients underwent endoscopic surgery in all surgical domains, such as abdominal, thoracic, mammary and thyroid gland, cardiovascular, obstetrics and gynecology, urologic, orthopedic, and plastic surgery. The 14th National Survey of Endoscopic Surgery conducted by the JSES demonstrated the status of laparoscopic surgery in Japan in 2016-2017.Asian journal of endoscopic surgery, Jan. 2020, Asian journal of endoscopic surgery, 13(1) (1), 7 - 18, English, Domestic magazineScientific journal

- © 2019 John Wiley & Sons, Ltd. Background: Although chemotherapy is a core treatment for esophageal cancer, some patients develop drug resistance. Gene screening with transposons (i.e. mobile genetic elements) is a novel procedure for identifying chemotherapy-resistant genes. Transposon insertion can randomly affect nearby gene expression. By identifying the affected genes, candidate genes can be found. The present study aimed to identify cisplatin (CDDP)/5-fluorouracil (5-FU)-resistant genes in in vitro human esophageal squamous cell carcinoma with transposons. Methods: After establishing transposon-tagged cells, we obtained CDDP/5-FU-resistant colonies. A polymerase chain reaction and sequencing were used to identify the transposon inserted site and candidate CDDP/5-FU resistant genes. Focusing on one candidate gene, we confirmed CDDP/5-FU resistance by comparing the IC50 between drug-resistant and wild-type cells. Furthermore, we investigated gene expression by a real-time polymerase chain reaction. Finally, we mediated the candidate gene level with small interfering RNA to confirm the resistance. Results: Thirty-nine candidate genes for CDDP/5-FU resistance were identified. Nineteen were for CDDP resistance and 27 were for 5-FU resistance. Seven genes, THUMP domain-containing protein 2 (THUMPD2), nuclear factor interleukin-3-regulated protein (NFIL3), tyrosine-protein kinase transmembrane receptor 2 (ROR2), C-X-C chemokine receptor type 4 (CXCR4), thrombospondin type-1 domain-containing protein 2 (THSD7B) alpha-parvin (PARVA) and TEA domain transcription factor 1 (TEAD1), were detected as candidate genes in both colonies. Regarding THUMPD2, its expression was downregulated and knocking down THUMPD2 suggested drug resistance in both drugs. Conclusions: Thirty-nine candidate genes were identified with transposons. The downregulation of THUMPD2 was suggested to play a role in multidrug resistance in in vitro esophageal squamous cell carcinoma.Journal of Gene Medicine, Dec. 2019, Journal of Gene Medicine, 21(12) (12), e3135, English, International magazineScientific journal
- © 2019, Society of Surgical Oncology. Background: Cervical esophageal cancer (CEC) patients whose larynx function cannot be preserved often undergo chemoradiotherapy, whereas those with residual or recurrent lesions undergo a pharyngo-laryngo-esophagectomy (PLE); however, some need to undergo a pharyngolaryngectomy with total esophagectomy (PLTE) for synchronous or metachronous esophageal cancer. We retrospectively evaluated the relationship between preoperative irradiation (or the extent of esophageal resection) and postoperative endocrine complications in CEC, including hypothyroidism and hypoparathyroidism. Methods: The cancers of 35 (5.4%) of 678 esophageal cancer patients with esophagectomy treated in 2000–2017 were CECs. We also analyzed the 17 cases of CEC patients who underwent PLE with thyroid lobectomy—11 with irradiation before PLE and 6 without irradiation. Seven patients underwent a PLTE. Results: Hypothyroidism and hypoparathyroidism occurred in 14 and 12 patients, respectively. The hypothyroidism rate was significantly higher in patients with irradiation versus those without irradiation (100% vs. 50%; p = 0.010), and the hypoparathyroidism rate was significantly higher in the PLTE versus non-PLTE patients (100% vs. 50%; p = 0.026). The mean levothyroxine dosage was 1.60 μg/kg/day in the PLE patients post-irradiation. Conclusions: Irradiation appears to be a risk factor for hypothyroidism after PLE with thyroid lobectomy, while PLTE might have some effect on hypoparathyroidism. Due to vocal function loss, PLE patients may experience symptoms from endocrine complications. Levothyroxine treatment soon after PLE for post-irradiation patients and patients requiring as-needed calcium or vitamin D supplementation based on biochemical hypocalcemia for PLE (especially PLTE), may be effective in preventing symptomatic endocrine complications.Annals of Surgical Oncology, Oct. 2019, Annals of Surgical Oncology, 26(11) (11), 3711 - 3717, English, International magazineScientific journal
- © 2019, The Japan Esophageal Society and Springer. Background: The surgical Apgar score (SAS) has been a useful predictor of postoperative complications in several types of cancer. However, there are few reports about the correlation of SAS and esophageal cancer. This study aimed to examine the utility of SAS as a predictor of major complications, particularly anastomotic leakage, in patients who underwent transthoracic esophagectomy, and investigate the correlation between SAS and patient prognosis. Methods: This is a single-center, retrospective observational study. A total of 190 patients who underwent esophagectomy for esophageal cancer in 2012–2016 were reviewed to find the correlation between SAS and postoperative complications (Clavien–Dindo classification III or higher). SAS was calculated based on intraoperative estimated blood loss, lowest mean arterial pressure, and lowest heart rate. Major complications included anastomotic leakage, respiratory, cardiac, recurrent nerve palsy, chylothorax, and other complications. We also reviewed how SAS was correlated with 3 year overall survival (OS) and recurrence-free survival (RFS). A high SAS was defined as ≥ 6, and a low SAS as < 6. Results: On univariate analysis, SAS showed a statistical significance in all major complications and anastomotic leakage. On multiple logistic regression analysis, a low SAS was detected as a risk factor of the major complications and anastomotic leakage, with a significant difference. Moreover, we conducted survival analysis with SAS; however, we could not detect that a low SAS had a negative impact on OS and RFS. Conclusions: A low SAS can be a predictor of postoperative complications, especially anastomotic leakage. However, SAS was not correlated with OS or RFS.Esophagus, Oct. 2019, Esophagus, 16(4) (4), 386 - 394, English, Domestic magazineScientific journal

- © 2018, The International Gastric Cancer Association and The Japanese Gastric Cancer Association. Background: Although some predictive factors of long-term survival after a distal gastrectomy for gastric cancer have been reported, only few studies have predicted long-term outcomes based on preoperative parameters. We aimed to evaluate the reliability of perioperative risk calculator for predicting overall survival (OS) after distal gastrectomy in patients with gastric cancer. Methods: Overall, 337 patients (225 males, 112 females) who had undergone a distal gastrectomy for gastric cancer at the Keio University Hospital, Tokyo, Japan, between January 2009 and December 2013 were enrolled in this study. We investigated the reliability of a risk calculator for the prediction of OS. Results: In multivariate analysis, the risk models for operative mortality and 30-day mortality were identified as predictors of death. Time-dependent receiver operating characteristics (ROC) curve analysis indicated that the estimated area under the curve (AUC) value of the risk model for operative mortality was > 0.870 during the first postoperative 3 years. We set optimal cutoff values of the risk model operative mortality for OS using the Cutoff Finder online tool. The cutoff values of 4.117% were significant risk factors of death. Similar results were observed in the external validation set. Conclusions: We elucidated the associations among risk calculator values and OS rates of patients with gastric cancer. Time-dependent ROC curve analysis suggested that the AUC value of the risk model for operative mortality was high, indicating that this risk calculator would be useful for not only short-term outcomes, but also long-term outcomes.Gastric Cancer, May 2019, Gastric Cancer, 22(3) (3), 624 - 631, English, Domestic magazineScientific journal
- © 2019 Author(s). Introduction: The prevalence of surgical site infection (SSI) remains higher in gastrointestinal surgery than in other surgeries. Although several guidelines have indicated the efficacy of chlorhexidine and povidone-iodine in reducing the SSI rate, the optimal recommendation has still not been established. Therefore, it is necessary to determine the more effective antiseptic for surgical site preparation. Olanexidine (1.5% olanedine, Otsuka Pharmaceutical Factory, Tokushima, Japan), which is a new antiseptic in Japan, has antimicrobial activity against a wide range of bacteria, including Gram-positive and Gram-negative bacteria. Our study will contribute to determining a new antiseptic for use in gastrointestinal and other surgeries. Methods and analysis: We propose a multicentre, randomised controlled clinical trial for comparing two treatments, that is, 1.5% olanexidine or 10% povidone-iodine, for surgical skin preparation to prevent SSI in clean-contaminated gastrointestinal surgeries with surgical wounds. Patients aged ≥20 years at the time of consent will be included. The primary outcome measure is the 30-day postoperative SSI rate. For the primary analysis, which is aimed at comparing the treatment effects, the adjusted risk ratio and its 95% CI will be estimated using the Mantel-Haenszel method. Ethics and dissemination: The protocol was first approved by the Institutional Review Board of Keio University School of Medicine, followed by the institutional review board of each participating site. Participant recruitment began in June 2018. The final results will be published in international peer-reviewed medical journals.BMJ Open, May 2019, BMJ Open, 9(5) (5), e028269 - e028269Scientific journal

- © 2018, Société Internationale de Chirurgie. Background: Although esophagectomy is the only curative option for esophageal cancer, the associated invasiveness is high. Nasogastric (NG) tube use may prevent complications; however, its utility remains unclear, and the decompression period depends on the doctor. This study aimed to reveal the effect of conventional versus early NG tube removal on postoperative complications after esophagectomy. Methods: This single-center prospective randomized controlled clinical trial enrolled patients aged 20–80 years with histologically proven primary esophageal squamous cell carcinoma. Eighty patients admitted for transthoracic first-stage esophagectomy reconstructed with gastric conduit were randomly assigned (1:1) to the conventional and early NG tube removal groups. In the conventional NG tube removal group, the tube was removed on postoperative day (POD) 7; in the other, it was removed on POD 1. The occurrence rate of major complications, length of postoperative hospital stay, and NG tube reinsertion rate were compared between the groups. Results: The incidence of postoperative major complications such as pneumonia, anastomotic leakage, recurrent nerve palsy and gastrointestinal bleeding, and the NG tube reinsertion rate was not different between the groups. However, recurrent nerve palsy was more commonly observed in the conventional removal group; this difference was not significant. In terms of postoperative pneumonia, tumor location and field of lymph node dissection were significant risk factors. Conclusion: Although early NG tube removal did not reduce the rate of postoperative pneumonia, it could be performed safely. Hence, the NG tube can be removed earlier than conventional methods.World Journal of Surgery, Feb. 2019, World Journal of Surgery, 43(2) (2), 580 - 589, English, International magazineScientific journal

- © 2018 The Authors. Annals of Gastroenterological Surgery published by John Wiley & Sons Australia, Ltd on behalf of The Japanese Society of Gastroenterological Surgery Aim: The aim of the present study was to clarify esophagogastric junction (EGJ) carcinoma patients who are at high risk of upper and middle mediastinal lymph node (MLN) metastasis. Methods: This was a retrospective study and included 110 consecutive patients with EGJ carcinoma who underwent R0/R1 resection at Keio University Hospital between January 2000 and December 2013. Results: Of the 110 patients, 18 (16.3%) had MLN metastasis, and the number increased to 23 (20.9%) when recurrence cases were added (adenocarcinoma, N = 11; squamous cell carcinoma, N = 12). Patients whose tumor epicenter was located above the EGJ had a significantly higher incidence of MLN metastasis/recurrence (18/51 [35.3%]) than those whose tumor epicenter was located below the EGJ (5/59 [8.5%]). The MLN metastasis/recurrence rate was particularly high when the distance from the EGJ to the proximal edge of the primary tumor was >3 cm for the upper and middle mediastinum (18.8%). Patients in a selected group (≥T2 and tumor epicenter located above the EGJ or below the EGJ with ≥3 cm esophageal invasion) showed 17.9% and 15.4% upper and middle MLN metastasis/recurrence rates, respectively. Therapeutic value of MLN dissection was relatively high (#105 + 106: 8.9, #110: 12.2). Conclusions: Therapeutic value of MLN dissection to treat EGJ carcinomas was relatively high in patients with MLN metastasis. Our algorithm could select patients at high risk for MLN metastasis.Annals of Gastroenterological Surgery, Nov. 2018, Annals of Gastroenterological Surgery, 2(6) (6), 419 - 427, English, Domestic magazineScientific journal

- ENDOSCOPIC FINDINGS OF LARYNGOPHARYNGEAL AND ESOPHAGEAL INVOLVEMENT IN AUTOIMMUNE BULLOUS DISEASE<p>Background and Aim: Autoimmune bullous disease (ABD) is induced by autoantibodies against cell adhesion molecules, and blistering may occur on the mucous membranes of the eyes, nose, mouth, oral cavity, laryngopharynx, and esophagus. Endoscopic prevalence and features of ABD-associated esophageal lesions are not well known. We conducted the present study to assess the endoscopic prevalence of ABD-associated mucosal lesions. </p><p>Methods: Endoscopic prevalence of mucosal lesions, particularly laryngopharyngeal and esophageal lesions, was used as the primary endpoint to assess the significance of upper gastrointestinal endoscopy, and clinical and endoscopic features were secondary endpoints. </p><p>Results: Of 123 ABD patients, 50.4% had apparent oral or laryngopharyngeal lesions and 30.8% had laryngopharyngeal lesions. Esophageal lesions were detected through normal observation in 16.8% of affected patients, whereas 40.6% exhibited epidermolysis or blood blisters by mechanical inducement, regardless of esophageal mucosal lesion detection by normal observation. Additionally, 56.0% exhibited the Nikolsky sign with mechanical inducement. Of the 123 patients, 29.2% did not have exposed skin lesions. Of these patients, 77.7% had oral cavity or laryngopharyngeal lesions, 36.1% had esophageal lesions, and 58.3% exhibited the Nikolsky sign on esophageal mucosa. </p><p>Conclusion: It is important to determine the endoscopic characteristics and findings of ABD. ABD can be suspected from endoscopic findings. </p>Japan Gastroenterological Endoscopy Society, 2018, GASTROENTEROLOGICAL ENDOSCOPY, 60(8) (8), 1515 - 1526, Japanese

- The neutrophil elastase inhibitor sivelestat suppresses accelerated gastrointestinal tumor growth via peritonitis after cecal ligation and puncture.BACKGROUND: We examined whether tumor growth is enhanced by cecal ligation and puncture (CLP) and suppressed by a neutrophil elastase inhibitor, sivelestat. MATERIALS AND METHODS: C57BL/6 mice were divided in CLP/sivelestat, CLP alone, and control (simple laparotomy) groups. Murine CT26 colon carcinoma cells were injected subcutaneously into the back of each mouse and tumor growth and serum cytokine levels were assessed. RESULTS: Mice subjected to CLP alone exhibited enhanced tumor growth compared to controls with subcutaneously injected CT26 cells (0.64±0.24 g vs. 0.021±0.027 g, p<0.001), while treatment with CLP/sivelestat produced smaller tumors than CLP alone (0.28±0.23 g vs. 0.64±0.24 g, p=0.006). Cytokine assays showed suppressed production of interleukin (IL)-6 and IL-10 in the CLP/sivelestat group, and increased IL-6 and IL-10 in the CLP-alone group. CONCLUSION: Intra-abdominal inflammation induced by CLP enhances the growth of subcutaneously implanted tumors, while perioperative administration of sivelestat suppresses tumor growth by affecting systemic inflammation.Sep. 2013, Anticancer research, 33(9) (9), 3653 - 9, English, International magazineScientific journal

- Chemoradiotherapy for advanced gastric cancer<p>In the US and Europe, chemoradiotherapy has become a standard treatment not only for head and neck cancer, esophageal cancer, pancreatic cancer, and rectal cancer, but also for gastric cancer. In particular, chemoradiotherapy has been established as an adjuvant therapy. In Japan, it has not been established as a standard treatment. Its indications are limited, and it is often performed as palliative care. Disadvantages of radiation therapy for gastric cancer include the difficulty of establishing the area to irradiate due to peristaltic movement, risk of perforation and ulceration from high-dose radiation, and ineffectiveness against adenocarcinoma with low radiosensitivity. In recent years, technological advancement of radiation therapy has enabled pinpoint accuracy in the treatment of primary gastric lesions and regional lymph nodes. There has been much anticipation that chemoradiotherapy will become a part of multidisciplinary treatment for advanced cancer. This report describes the current state of chemoradiotherapy for gastric cancer in Japan and overseas, and outlines our approach to locally advanced gastric cancer.</p>Dec. 2012, Japanese Journal of Cancer and Chemotherapy, 39(13) (13), 2464 - 2468, English

- Phase I study of neoadjuvant chemoradiotherapy consisting of S-1 and cisplatin for patients with resectable advanced gastric cancer (KOGC-01)<p>Background: The prognosis for advanced gastric cancer is poor, with surgery as the only treatment for resectable advanced gastric cancer. Therefore, treatment options that might improve the prognosis are needed. To that end, neoadjuvant chemoradiotherapy with S-1 and cisplatin (CDDP) was investigated. Patients and Methods: The chemotherapy schedule included one cycle repeated after 6 weeks. S-1 was administered orally every day on days 1-21 and CDDP was infused on days 1, 8 and 15. Radiation therapy was started concurrently with chemotherapy and repeated daily on days 1-5, 8-12, 15-19, and 22-26. Results: A total of 10 patients were recruited. The first four patients were entered into level 1 (CDDP, 20 mg/m<sup>2</sup>). The next six patients were entered into level 0 (15 mg/m<sup>2</sup>), because of dose-limiting toxicity (delaying the second course of chemotherapy in two patients) that had been observed at level 1. The maximum tolerated dose (MTD) of CDDP was 20 mg/m<sup>2</sup>. Seven patients underwent surgery and all had an R0 (no residual tumor) resection without surgical complications. Conclusion: Neoadjuvant chemoradiotherapy with S-1 and CDDP may cause surgery to be deSep. 2011, Anticancer Research, 31(9) (9), 3079 - 3083, English

- <p>Background: Salvage esophagectomy is potentially the only treatment available that can offer a chance of long-term survival when definitive chemoradiotherapy (CRT) fails to achieve local control for patients with esophageal squamous cell carcinoma (ESCC). However, salvage esophagectomy is a highly invasive procedure with various postoperative complications compared to planned esophagectomy after neoadjuvant chemoradiotherapy (CRT). We hypothesize that severe postoperative complications may affect not only surgical mortality but also tumor recurrence and long-term survival for patients with salvage esophagectomy after definitive CRT. Methods: For the present study we reviewed the surgical procedures, postoperative complications, and the prognosis of 65 consecutive patients with thoracic ESCC who underwent the esophagectomy after neoadjuvant (neoadjuvant group: n = 40) or definitive (salvage group: n = 25) CRT. Results: Most patients underwent right-transthoracic extended esophagectomy and reconstruction using gastric conduit by way of subcutaneous route with left cervical anastomosis. The incidence of postoperative pneumonia was found to be higher in the salvage group than in theFeb. 2010, World Journal of Surgery, 34(2) (2), 277 - 284, English

- A case with micro gastric cancer in the remnant stomach was reported. This 57-years-old male patient was initially operated on June 1999, because of his advanced gastric cancer with surgical type 3 at the antrum, of which histological finding was moderately differentiated adenocarcinoma with a depth of pT3 (SE) and lymph node metastasis of pN2. At 1-year-follow up on June 7th, a reddish abnormal lesion was observed at lesser curvature of remnant stomach by gastroscopy. Since the biopsy specimen revealed signet-ring cell carcinoma, he was operated on July 2000. No lesion was observed macroscopically, while the histological findings indicated the lesion of signet-ring cell carcinoma of which size was 1mm. The present case was diagnosed as a micro early gastric cancer in the remnant stomach on 1-year-after the first operation for advanced gastric cancer. Follow-up endoscopy was thought to be useful not only for the recurrence of primary cancer but also to find the secondary cancer.Japan Gastroenterological Endoscopy Society Kanto Chapter, 2001, Progress of Digestive Endoscopy(1972), 58(2) (2), 78 - 79, Japanese
