Esophageal cancer is one of the common malignant tumors with high incidence and poor prognosis. Angiogenesis-related pathways play an important role in the occurrence and development of esophageal cancer. Vascular endothelial growth factor (VEGF) is the main mediator of angiogenesis. In addition to promoting angiogenesis and maintaining the survival of neovascularization, VEGF can also directly act on esophageal cancer cells and promote the occurrence and development of tumors. This article reviews the biology of VEGF and its effect on blood vessels, the expression of VEGF in esophageal cancer cells and its influencing factors, the role of VEGF in esophageal cancer cells, the immunomodulatory activity of VEGF and the clinical study of VEGF inhibitors. The purpose of this study is to provide a basis for more rational use of VEGF inhibitors in the treatment of esophageal cancer.
Conduit failure and conduit airway fistula are rare complications after esophagectomy, however they can be catastrophic resulting in high mortality. Survivors can expect a prolonged hospital course with multiple interventions and an extended period of time prior to being able to resume oral nutrition. High index of suspicion can aid in early diagnosis. Conduit failure usually requires a period of proximal esophageal diversion and staged reconstruction. Conduit airway fistulas may be amenable to endoscopic repair but this has a high failure rate and many patients will require surgical repair with closure of the fistula and interposition of vascularized tissue to minimize recurrence.
Esophageal cancer (EC) is the eighth dangerous cancer in the world. As the global population ages, the management of elderly patients with EC poses a challenge as they have many aging-associated diseases and physiological changes. In addition, the data on the tolerability of cancer treatment and the use of combined therapies in the patients to guide their treatment are limited. In this paper, we reviewed the literatures and discussed the effect of surgical resection and the potential complications of elderly patients. We reviewed the basic principles of combined therapy and the potential benefits of chemotherapy or chemoradiotherapy for patients and focused on the management of elderly patients with EC as well as the role of comprehensive assessment for aging to provide treatment options for elderly patients.
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.
ObjectiveTo compare the impact of early enteral nutrition (EN) and parenteral nutrition (PN) on the postoperative efficacy of esophageal cancer through meta-analysis of relevant randomized controlled trial (RCT).MethodsPubMed, Medline, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to April 2018 to identify potential RCT which assessed clinical efficacy between EN and PN for postoperative patients with esophageal cancer. According to the inclusion and exclusion criteria, two researchers independently screened and evaluated literature. Meta-analysis was performed by RevMan 5.3 software.ResultsA total of 30 RCT studies were selected, including 3 969 patients. Meta-analysis results showed that: there was a significant difference between EN and PN in postoperative anastomotic fistulas (I2=0%, OR=0.67, 95%CI 0.45-0.99, P=0.04), postoperative pulmonary infections (I2=0%, OR=0.42, 95%CI 0.32-0.55, P<0.000 1), postoperative albumin levels (I2=38%, MD=0.78, 95%CI 0.51-1.06, P<0.000 01),time of first anal exhaust after operation (I2=0%, MD=–23.16, 95%CI –25.16-21.16, P<0.000 01) and postoperative incision infection (I2=0%, RR=0.36, 95%CI 0.21-0.64, P=0.000 5).ConclusionCompared with PN, early EN can significantly reduce the incidence of major postoperative complications and shorten the time of first anal exhaust after surgery. In addition, EN is superior to PN in improving nutritional status, increasing weight and reducing costs and side effects.
Esophageal carcinoma is a kind of common malignant tumor in the digestive tract. Although a lot of basic researches and clinical trials have been carried out all over the world, neither the diagnostic level nor the therapeutic effects have been obviously improved. The 5-year survival rate of esophageal cancer patient is still lower than that of other malignant tumors. Up to now, some frontier researches consider that the reason of the esophageal carcinoma being difficult to cure is related to the stem cells in it. Elimination or suppression of these stem cells may bring new hope for the treatment of esophageal cancer. This article generally introduces the specific markers, separation and indentification methods about the esophageal cancer stem cell. The targeted therapy is also mentioned.
Objective To explore the predictive value of cardiopulmonary exercise test (CPET) combined with clinical indexes in the postoperative complications. Methods The clinical data and CPET data (including lung function) of patients undergoing radical esophagectomy in Xuzhou Central Hospital from January 2018 to March 2022 were collected. Univariate analysis and multivariate logistic regression analysis were used to analyze the meaningful evaluation index for the occurrence of postoperative complications. Results A total of 77 patients with esophageal cancer were included, including 59 (76.6%) males and 18 (23.4%) females aged 47-80 years. There were 42 (54.5%) patients in the non-complication group and 35 (45.5%) patients in the complication group. Univariate analysis results showed that the occurrence of postoperative complications was significantly correlated with age, body mass index (BMI), smoking index, tumor stage, the length of postoperative hospital stay, peak work rate (WRpeak), peak kilogram oxygen uptake (VO2peak/kg), the ventilatory equivalent for carbon dioxide slope (VE/VCO2 slope), forced expiratory volume in the first second/forced vital capacity (FEV1/FVC) and maximum expiratory flow rate (MMEF) (P<0.05). The results of multivariate logistic regression analysis showed that BMI [OR=1.35, 95%CI (1.03, 1.77), P=0.031], peakVO2/kg [OR=0.64, 95%CI (0.45, 0.93), P=0.018], oxygen uptake-anaerobic threshold (ATVO2) [OR=0.66, 95%CI (0.44, 0.98), P=0.044] and VE/VCO2 slope [OR=1.49, 95%CI (1.10, 2.02), P=0.011] were the related indexes of complications after radical resection of esophageal cancer. The sensitivity of BMI, VO2peak/kg, ATVO2/kg and VE/VCO2 slope in predicting postoperative complications was 82.10%, and the specificity was 87.44%, 95%CI (0.744, 0.955). Conclusion BMI, VO2peak/kg, ATVO2/kg and VE/VCO2 slope can be used as predictors for postoperative complications of esophageal cancer.
Abstract: Objective To determine the effects of early enteral nutrition (EEN) on postoperative recovery in elderly patients with esophageal cancer. Methods We included 100 elderly patients with esophageal cancer who were admitted at the PLA 100 Hospital between January 2006 and April 2010, and whose diagnoses were confirmed by pathological examination. The patients were divided into an early enteral nutrition (EEN) group and a parenteral nutrition (PN) group, with 50 patients in each group. There were 32 males and 18 females with an average age of 72 years in the EEN group. There were 30 males and 20 females with an average age of 69 years in the PN group. We analyzed the effect of the nutrition administration method on bowel function recovery, hospital stay, complication rate, and nutritional status one week after surgery. Results The anal exhaust time (45.3±12.7 h vs. 73.6±11.7 h), time until anal defecation (80.5 h±15.6 h vs. 140.1±13.2 h), and hospital stay (13.0±1.8 d vs. 15.2±3.3 d) in the EEN group were all shorter than those in the PN group (Plt;0.05). The rates of lung infection, anastomotic leakage, and cardiac complications in the EEN group were significantly lower than those of the PN group (Plt;0.05). One week after the operation, the serum albumin (ALB), peripheral blood lymphocytes, transferrin, and 24 h urea nitrogen (BUN) in the EEN group were higher than those in the PN group (Plt;0.05). Conclusion Compared with parenteral nutrition, enteral nutrition can promote metabolic function in elderly patients after recovery, reduce morbidity, and promote recovery.

ObjectiveTo investigate the diagnostic value and the best criteria of multiplanar reconstruction (MPR) of spiral CT in recurrent laryngeal nerve lymph node metastasis.MethodsWe performed multiplanar reconstruction of the spiral CT data of 138 esophageal carcinoma patients admitted to our hospital between December 2016 and June 2019, including 113 males and 25 females with an average age of 47-85 (63.03±15.58) years. The short and long diameters of recurrent laryngeal nerve lymph nodes were measured respectively, and then ratio of short to long diameter was calculated. The three parameters were contrasted with the pathological results and the receiver operating characteristic (ROC) curves for the parameters were drawn.ResultsOf the 138 patients, 291 left recurrent laryngeal nerve lymph nodes were dissected with an average number of 0-14 (2.11±0.41) per patient and the metastasis rate was 16.70%; while 436 right ones were dissected with the average number of 0-17 (3.16±0.45) per patient and the metastasis rate was 21.00%. The total metastasis rate was 29.70%. In the diagnosis of lymph node metastasis, the areas under ROC curve for short and long diameters as well as the ratio of short to long diameter of left recurrent laryngeal nerve lymph nodes were 0.808, 0.779, 0.621, respectively, while those for the right ones were 0.865, 0.807, 0.637, respectively.ConclusionThe metastasis rate of recurrent laryngeal nerve lymph nodes is high and the short diameter has a higher diagnostic value for recurrent laryngeal nerve lymph node metastasis.
