en: Prognostic Impact of CXCR7 and CXCL12 Expression in Patients with Esophageal Adenocarcinoma.

en: High CXCR7 expression was associated with poor prognosis in patients with EAC, and high expression of CXCR7 with its ligand CXCL12 had a stronger association with prognosis. Further study of this potential biomarker using whole tissue samples and a larger sample size is warranted.

ja: High CXCR7 expression was significantly associated with lymphatic invasion (present vs absent, P = 0.005) and higher number of lymph node metastases (pN0-1 vs pN2-3, P = 0.0014). Patients with high CXCR7 expression (n = 23) were associated with worse overall (OS) and disease-free survival (DFS) (P = 0.0221, P = 0.0090, respectively), and patients with high CXCL12 (n = 24) tended to have worse OS and DFS (P = 0.1091, P = 0.1477, respectively). High expression of both CXCR7 and CXCL12 was an independent prognostic factor for OS and DFS on multivariate analysis (HR = 0.3, 95% CI: 0.1-0.9, P = 0.0246, HR = 0.3, 95% CI: 0.1-0.8, P = 0.0134, respectively).


en: Biomarkers predicting the response to chemotherapy and the prognosis in patients with esophageal squamous cell carcinoma.

en: The prognosis of patients with esophageal squamous cell carcinoma (ESCC) has been improved by multidisciplinary therapy with chemoradiotherapy and surgery, but it remains poor. Advanced stage, malignant potential, and chemo-resistance contribute to the poor prognosis. Here, we attempted to identify predictive factors of the response to chemotherapy and the prognosis of ESCC patients. We examined 51 ESCC patients who were treated with chemotherapy followed by radical surgery, and 23 patients who were treated with chemotherapy alone. We conducted quantitative reverse transcription-polymerase chain reaction gene expression analysis using RNA extracted from 74 tumor tissue samples collected before chemotherapy and 67 tumor tissue samples collected after chemotherapy, focusing on PIK3CA, AKT-1, mTOR, 4E-BP1, p70S6K, PD-L1, and PD-L2. The proportions of patients with high expressions of AKT-1 and PD-L1 before chemotherapy were significantly higher among the non-responders than among the responders (p = 0.034, p = 0.020, respectively). Multivariate analyses revealed that high PD-L1 expression before chemotherapy was associated with poor response to chemotherapy (odds ratio 2.998; 95% CI 1.043-8.619; p = 0.042) and high p70S6K expression before chemotherapy was a poor prognostic factor (hazard ratio 2.518; 95% CI 1.058-5.988; p = 0.037). In addition, the patients with high expression of PD-L1 and PD-L2 in the tumors after chemotherapy had significantly worse survival than those with low expression of these genes (p = 0.012, p = 0.007, respectively). These results demonstrated that PD-L1 and p70S6K in the primary ESCC tissues were related to a poor response to chemotherapy and poor prognosis, respectively.

en: A CASE OF VAGUS NERVE SCHWANNOMA DIFFICULT TO DISTINGUISH FROM LYMPH NODAL METASTASIS OF ESOPHAGEAL CANCER.

en: In this report, we describe a rare case of vagus nerve schwannoma associated with esophageal cancer. A 70-year-old man visited our hospital complaining of worsening dysphagia. His upper gastrointenstinal endoscopy revealed a mass in the esophagus. A contrast-enhanced chest computed tomography also detected a 15 mm nodule attached to the tracheal membrane. This nodule was diagnosed as a metastatic lymph node. Although the primary tumor reduced after neoadjuvant chemotherapy, the nodule remained intact ; it showed fluorodeoxyglucose accumulation on positron emission tomography. We had a clinical diagnosis of stage III after neoadjuvant chemotherapy and underwent surgery. Intraoperatively, the nodule could not be detached from the right vagus nerve ; therefore, we excised the nodule along with the adjacent vagus nerve. The nodule was pathologically diagnosed as a vagus schwannoma. The nodule was not a regional lymph node metastasis of esophageal cancer. His postoperative course was uneventful, and he is currently undergoing outpatient follow-up without recurrence. J. Med. Invest. 68 : 205-208, February, 2021.

en: Thoracoscopic Oesophagectomy Using Prone Positioning for Oesophageal Cancer With Right Aortic Arch: A Case Report.

en: There exist only a few reports of thoracoscopic oesophagectomy for EC with RAA. Sufficient preoperative preparation and sharing an adequate strategy for the surgical approach with the surgical team are definitely necessary. Although the thoracoscopic approach for EC with RAA is useful, more considerations are needed for some issues.

en: Short-Term Outcomes of Laparoscopic Distal Gastrectomy for Advanced Gastric Cancer.

en: The purpose of this study was to investigate the oncologic outcomes of laparoscopic distal gastrectomy (LDG) for advanced gastric cancer (AGC). Between April 2003 and March 2014, LDG was performed for 392 patients, 91 patients (23.2%) had histopathologically diagnosed AGC beyond T2 depth. The clinicopathological features, postoperative outcomes, mortality, morbidity, recurrence rate, and survivals of those patients were reviewed. The TNM stages of the tumor were IB in 26 patients (28.5%), IIA in 20 (21.9%), IIB in 18 (19.7%), IIIA in 13 (14.2%), IIIB in 6 (6.5%), IIIC in 6 (6.5%), and IV in 2 (2.1%). Major morbidity occurred in 14 patients (15.3%), with no postoperative mortality. Median follow-up was 24.5 months; 10 patients developed recurrence during the follow-up period, and 10 patients died, including 6 cancer deaths. The 5-year overall and disease-free survival rates were 76.8% and 72.6%, respectively. By stage, OS/DFS was 92.3%/91.8% in stage IB, 85.4%/85.4% in stage II, and 49.3%/26.9% in stage III. Oncologic outcomes were good in patients with AGC, especially with stage IB-IIB, who underwent LDG. LDG appears to be an effective approach for treating stage IB and II gastric cancer.

en: Mesh-Airtight-Preperitoneum: a simple method for confirming mesh placement in transabdominal preperitoneal repair of inguinal hernia.

en: We devised a method for confirming the position of mesh placed during transabdominal preperitoneal repair (TAPP) of an inguinal hernia. The preperitoneum is sufficiently detached, and the mesh is fixed in place as usual. Before completely closing the peritoneum, pressure is applied from outside the body and inside the abdominal cavity to remove as much air as possible from the detached preperitoneum; the peritoneum is then sutured using a V-Loc(TM) closure device so that it does not constrict. By releasing the pressure all at once, the airtightness of the preperitoneum is maintained, and the position of the mesh can be observed through the translucent peritoneum. This method, called Mesh-Airtight-Preperitoneum (MAPP), could become widely used as a simple technique for confirming mesh position in TAPP. J. Med. Invest. 63: 270-273, August, 2016.


en: [Pathological Complete Response in a Case of Advanced Esophageal Cancer Invading Aorta Treated by Preoperative Chemotherapy with Docetaxel and Cisplatin plus 5-FU].

en: The patient was a 64-year-old man, diagnosed as cStage IVa esophageal cancer invading the aorta with lymph node metastasis. He received combination chemotherapy with docetaxel/cisplatin/5-FU(DFP therapy). After one course, CT and endoscopic examination showed remarkable reduction of the primary lesion and lymph node metastasis. We performed subtotal esophagectomy and gastric tube reconstruction by the retroposterior mediastinum route. The pathological specimen evidenced fibrosis and infiltration of inflammatory cells on almost all layers, but showed no viable malignant cells in the middle thoracic esophagus. Therefore, the pathological effect was judged as Grade 3(pCR). This case suggested that DFP combination chemotherapy may prove to be a useful treatment for advanced esophageal cancer with invasion to other organs.

en: Laparoscopic permanent sigmoid stoma creation through the extraperitoneal route.

en: About 50% of patients who have a permanent stoma experience some degree of parastomal hernia formation. To prevent this complication, the extraperitoneal route is considered to be more effective than the transperitoneal route in the case of open colorectal surgery. This technique also has superiority in avoiding postoperative intestinal obstruction. Although laparoscopic surgery for rectal cancer has not been proved to be as safe as open surgery by a randomized-controlled trial, some studies have shown the equality of long-term results with laparoscopic low anterior resection and laparoscopic abdominoperineal resection. It is anticipated that cases of laparoscopic abdominoperineal resection will increase in the near future. However, a laparoscopic technique for creation of a permanent stoma has hardly been discussed. Most operative procedures for laparoscopic stoma creation have been performed with transperitoneal route, which may cause parastomal hernia and/or intestinal obstruction. This report describes a laparoscopic technique for permanent sigmoid stoma creation through the extraperitoneal approach.

ja: 食道癌頸部リンパ節再発による症状に対して緩和ケアを実践した2症例

en: Our department aggressively performs initial treatment for esophageal carcinoma with multidisciplinary approaches, and not only positively treats patients with recurrence or metastasis but also manages those in an advanced stage by following the wishes of patients and their families as much as possible. However, many patients with esophageal carcinoma develop digestive tract and tracheal problems with progression of the disease, and the palliation of symptoms and continuation of home care often become difficult. In such patients, it is important to secure and maintain the route of hydration and nutrition when oral fluid and food intake becomes difficult, and to control respiratory symptoms for the promotion of home care and palliation of symptoms in the terminal stage. In this report, we present 2 patients managed by palliative care until death while supporting home care by maintaining enteral nutrition using gastrostomy for esophageal narrowing due to cervical lymph node recurrence, and controlling the cough reflex and dyspnea associated with the development of a cervical lymph node-tracheal fistula through morphine hydrochloride administration.
