Objective To evaluate the influence of fast-track surgery in perioperative period on the clinical outcomes of patients at nutritional risk in respectable esophageal cancer surgery perioperatively.Methods A total of 170 esophageal carcinoma patients receiving radical operation in our hospital from January 2008 to December 2013 were randomly divided into two groups by simple random method (n =85 each):one group was treated with the new concept of FTS-based on nutritional risk screening (FTS group),and the other control group received conventional perioperative management (CPM group).The postoperative first passage of flatus and defecation,time to drainage tube removal,postoperative hospital stay,and morbidity of the postoperative complication were recorded and compared.Results The time to drainage tube removal and length of postoperative hospital stay were significantly lower in the FTS group than those in the CPM group,and the overall postoperative complication rate was 7.06％ (6/85) in the FTS group and 20.00％ (17/85) in the CPM group (all P ＜0.05).In FTS group,the first flatus time was (59.01 ±2.73) h,the first defecation time was (3.35 ± 1.37) d,removing time of chest tube was (2.76 ±0.34) d,and postoperative hospital days was (8.16 ± 0.80) d; in the control group,they were (90.16 ±2.82) h,(4.78 ± 1.74) d,(4.39 ±0.25) d,and (10.93 ± 1.39) d respectively,showing significant differences (all P ＜0.05).The operative time was similar between these two groups.Conclusion The new concept of FTS by nutrition risk screening and intervention apparently can accelerate recovery after esophagngastrectomy,reduce the rate of overall complications,promote bowel function recovery,and decrease morbidity in the perioperative period for patients with esophageal carcinoma.

Objective In a prospective randomized controlled pilot study, effects of postoperative pulmonary complications on a conservative treatment surgery (CTS) and fast track surgery (FTS) treatment regimen in non-small cell lung cancer (NSCLC) patients undergoing pulmonary lobectomy were compared.Methods Eighty patients who underwent radical pulmonary lobectomy surgical treatment for non-small cell lung cancer disease from January 2008 to May 2010 in our hospital were random assigned to either fast track surgery treatment (40 FTS group) or conservative treatment surgery regimen (40 CTS group). Study endpoints were pulmonary complications ( pneumonia, atelectasis, prolonged air leak ＞ 7 days); Further parameters assessed in the postoperative course of patients were the need for postoperative mechanical ventilation, temperature at the end of the operation, length of stay (LOS) on intensive care unit (ICU) and day of discharge. Results The rate of postoperative pulmonary complications was 34. 21% in CTS group and 8. 33% in FTS group ( P ＜0. 05). Median length of stay on ICU was comparable in both groups ( 1 day),but the day of discharge was significantly different in both groups [( 11. 1 ±3.6)d vs ( 16. 6 ±5.7)d, P ＜0. 01]. Conclusion Using this fast track clinical pathway, the rate of pulmonary complications could be significantly decreased as compared to a conservative treatment regimen. Our results supported the implementation of an optimized perioperative treatment in lung surgery for non-small cell lung cancer patients undergoing radical pulmonary in order to reduce pulmonary complications after major lung surgery.

BACKGROUND:There is no effective therapy for obliterative bronchiolitis after tracheal transplantation. A therapeutic strategy at microRNA (miRNA) molecular level plays a crucial role in the prevention and treatment of complications after organ transplantation.
OBJECTIVE:To analyze the miRNA differential expression profile in response to obliterative bronchiolitis after orthotopic tracheal transplantation in rats.
METHODS:The obliterative bronchiolitis model after lung transplantation was established through orthotopic tracheal transplantation in inbred strains of rats, and then was identified using histoIogical examination. Total miRNAs were detected by miRNA array and significantly differential expressed miRNAs were filtrated in the transplanted trachea tissues. The miRNA-146a, miRNA-155 and miRNA-451 with significantly differential expressions were used for relative quantitative study. Quantitative real-time reverse transcription-polymerase chain reaction was applied to verify the reliability of miRNA array results.
RESULTS AND CONCLUSION:The pathological examination showed that, obliterative bronchiolitis model in rats was successful y established at 4 weeks after orthotopic tracheal transplantation. A total of obliterative bronchiolitis-related 29 miRNAs were found in miRNA expression profiles, including 14 miRNAs with significantly down-regulated expression and 15 miRNAs with significantly up-regulated expression. Among them, the significantly up-regulated miRNAs (miRNA-146a and miRNA-155) and the significantly down-regulated miRNA-451 were involved in immuno-inflammatory reaction. The miRNAs play an important role in regulating pathophysiological changes of obliterative bronchiolitis after lung transplantation.

Nowadays, the popularization of endoscopic technology makes a substantial increase in the diagnosis rate of esophageal multiple primary carcinoma. However, the multiple primary carcinoma combined with esophageal cancer, lung cancer and cardiac cancer is relatively rare. This paper reported a 64-year-old male with multiple primary cancer who received one-stage complex radical surgery, including radical resection of esophageal cancer, lung cancer and cardiac cancer. After the operation, the patient presented chylothorax and conservative treatment was ineffective. Then we preformed ligation of thoracic duct through single-portal thoracoscope. The patient recovered successfully after surgery and the follow-up results showed well.

Objective    To investigate the clinical characteristics of thoracic esophageal-gastric cancer (TEGC) and the safety and effectiveness of secondary reconstruction of thoracic and gastrointestinal tract after esophageal and preventriculus cancer (esophagogastric junction) surgery. Methods    The clinical data of 353 patients with esophageal and preventriculus cancer who underwent endoscopic review from July 2007 to December 2019 were retrospectively analyzed. A total of 31 (8.78%) patients with relapsed or recurrent TEGC were found, including 24 males and 7 females with a mean age of 58.5 years (range: 42 to 68 years). There were 18 (58.06%) patients of adenocarcinoma and 13 (41.94%) squamous cell carcinoma. All patients underwent TEGC resection and secondary reconstruction of thoracic gastrointestinal tract. Thoracoabdominal computed tomography (CT) and upper gastrointestinal imaging (GI) were performed during follow-up, and gastroscopy was performed for suspected patients. All the patients were followed-up till death or December 30, 2019. The survival rate was calculated by Kaplan-Meier method, and the survival was analyzed using the log-rank test. Results    Thirty-one patients underwent thoracic esophagectomy and gastric cancer resection, and then reconstruction of the thoracic and gastrointestinal tract. Eight patients underwent residual gastroesophageal thoracic anastomosis, 13 patients colon esophagectomy, 6 patients jejunal esophagectomy (1 patient esophago-jejunal Roux-en-Y anastomosis), and 4 patients cervical esophagogastric anastomosis. The mean operation time and intraoperative blood loss were 404.8 (340-475) min and 378.4 (180-620) mL. The postoperative complications ocurred in 4 patients, including 3 patients of pulmonary infection and 1 patient of cervical incision infection. The mean hospital stay was 17.1 (14-21) d. All patients were followed up, the median survival time of 11 patients in stage Ⅰ-ⅡA was 25 (19.8-35.0) months and 20 patients in stage ⅡB-ⅢA was 16 (12.5-19.5) months. There was a significant difference between the two groups (χ2=7.840 8, P<0.01). Conclusion    Postoperative relapsed and recurrent TEGC occurs after the surgery for esophageal and preventriculus cancers, most of which are caused by metachronous gastric cancer or residual esophageal carcinoma recurrence which leads to invasion of the thoracic and gastric wall. Regular endoscopic review is the main method after operation. It is technically safe and feasible to reconstruct the thoracic and esophageal digestive tract in patients with TEGC after reoperation, which can benefit the survival of patients.

Lung cancer is the leading cause of cancer-related deaths worldwide. Although improvement has been achieved in platinum-based chemotherapy and tyrosine kinase inhibitors-based molecular targeted therapy, they still have limitations. Immunotherapy has recently emerged as a very effective new treatment, and there is now growing enthusiasm in cancer immunotherapy worldwide. We summarized the effects of immune checkpoint inhibitors in clinical trials, and the current status and progress of anti programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) agents in lung cancer treatment. Attention has been paid to finding out the factors which influence the therapeutic effect of anti-PD-1/PD-L1 therapy and reducing the occurrence of adverse events.
