Background Because esophageal carcinosarcoma (ECS) is rare, a treatment strategy similar to that employed in esophageal cancer is usually applied. However, the clinicopathological features and the treatment effects of preoperative chemotherapy or chemoradiotherapy (CT/CRT) are not well known. Methods We retrospectively evaluated clinical and pathological characteristics of consecutive patients with...
Smoking cigarettes and drinking alcoholic beverages are considered very important risk factors for adverse health effects, such as many types of cancer and cardiovascular disease. In this study, we evaluated the influence of smoking and drinking cessation on risk of esophageal cancer, by means of meta-analysis. We extracted 205 studies by conducting a systematic literature search. Thirty-five studies...
Background There are differences in the histological diagnostic criteria for early stage gastrointestinal carcinoma between Western and Japanese pathologists. Western histological criteria of carcinoma are “presence of stromal invasion of neoplastic cells”, while Japanese criteria are “the degree of cytological and structural abnormality of neoplastic cells, regardless of stromal invasion”. The aim...
Backgrounds and aim Anastomotic leak (AL) following esophagectomy for esophageal cancer (EC) remains an important cause of prolonged hospitalization and impaired quality of life. Recently, indocyanine green (ICG) fluorescein imaging has been used to evaluate the gastric conduit blood supply during EC surgery. Although several factors have been reported to be associated with AL, no studies have evaluated...
Background To investigate the impact of the preoperative patient-related factors on survival after esophagectomy in patients with esophageal cancer. Methods We retrospectively reviewed 140 patients with esophageal cancer who underwent esophagectomy. Preoperative comorbidities, nutritional and inflammation status including the neutrophil to lymphocyte ratio and Glasgow prognostic score (GPS), and...
Background In patients treated surgically for esophageal cancer, time-dependent data on nutritional status from the perioperative to postoperative period are questionable. We investigated time-dependent data on weight, body composition, and nutritional indices of patients with esophageal cancer from the preoperative period through the 12-month postoperative period. Methods Eighty patients with esophageal...
Background Although several clinical trials of vaccination and cellular immunotherapy for esophageal cancer have been reported, clinical trials of anti-CD3-activated autologous αβT cell therapy for patients with esophageal squamous cell carcinoma are limited. Method A total of five patients with recurrent esophageal squamous cell carcinoma were enrolled in this prospective pilot study. Peripheral...
Background A variety of endoscopic findings are considered useful for the diagnosis of eosinophilic esophagitis (EoE). However, the diagnostic consistency among Japanese endoscopists for those findings has not been fully examined. The aim of this study was to investigate the inter- and intra-observer agreement for endoscopic findings suggesting EoE. Methods Forty endoscopists, including 20 with...
Background Identifying clinical resectability of locally advanced esophageal squamous cell carcinoma (ESCC) is important, although inter-evaluator heterogeneity (IEH) could exist, especially in borderline resectable (BLR) cases. To investigate the extent of heterogeneity, we conducted clinical diagnostic imaging questionnaires. Materials and methods Five cases with clinical T3 or T4 cases, which...
Eight years after surgical treatment for breast cancer, serum p53 antibody levels suddenly increased in a 67-year-old woman without recurrent signs of cancer. Early esophageal squamous cell carcinoma was detected by endoscopic screening. After endoscopic submucosal dissection was completed, serum p53 antibody levels decreased to be in the normal range. Serum p53 antibody monitoring can be helpful...
