ObjectiveTo analyze the clinical and dosimetric impacts on radiation pneumonitis (RP), and provides data for radiotherapy planning. MethodsWe reviewed 59 non-operative esophageal cancer patients who underwent radiotherapy from October 2010 to November 2012 to identify the correlation between the clinical and dosimetric parameters with acute radiation pneumonitis (ARP) and severe acute radiation pneumonitis (SARP) by t-Test, Chi-Square Test and logistic regression analysis. ResultsAmong the 59 patients, 33 (55.9%) developed ARP, in whom 9 (15.3%) developed SARP. Univariate analysis showed that lung infection during radiotherapy, mean lung dose (MLD), and dosimetric parameters are significantly correlated with RP. Multivariate analysis revealed lung infection during radiotherapy, MLD≥13 Gy, and V30≥13% were significantly correlated with the increasing risk RP. ConclusionLung infection during radiotherapy, MLD, and V30 are the influencing factors of RP, which should be seriously considered when formulating radiotherapy plan to avoid RP.
ObjectiveTo investigate the application value of modified gastric tube in surgery for mid- and lowerthoracic esophageal cancer compared with gastric tube. MethodsA total of 221 patients with mid- and lower-thoracic esophageal cancer who underwent esophagectomy between October 2009 and June 2013 in our hospital were recruited in the study. They were randomly divided into a modified gastric tube group (n=108) and a gastric tube group (n=113). There were 67 males and 41 females at age of 63.50±6.75 years (ranged 47-73 years) in the modified gastric tube group, including 62 cases of middle esophageal cancer and 46 cases of lower esophageal cancer. There were 69 males and 44 females at age of 63.38±7.21 years (ranged 49 to 76 years) in the gastric tube group, including 68 cases of middle esophageal cancer and 45 cases of lower esophageal cancer. The results of surgery and morbidities were recorded. The respiratory functions were recorded at 3 days before surgery, 1 week and 4 weeks after surgery, respectively. ResultsAll surgeries were successfully performed in two groups. There was 1 case of death and 1 case of anastomotic leakage in the gastric tube group. There was no death or anastomotic leakage occurred in the modified gastric tube group. There was statistical difference in the operation time between the modified gastric tube group and the gastric tube group (150.65±11.88 min vs. 174.58±11.99 min, P<0.05). There were no statistical differences in the amount of bleeding during operation or the length of hospital stay between two groups (P>0.05). There were no statistical differences in respiratory function between two groups at 1 week or 4 weeks after surgery (P>0.05). ConclusionFor patients with mid- and lower-thoracic esophageal cancer, modified gastric tube has a good clinical application value compared with gastric tube. It is easy and safe, and can decrease the operation time without aggravation of pulmonary function after operation. It is a better esophagus reconstruction method in esophagectomy for mid- and lower-thoracic esophageal cancer in primary hospitals.
Objective To compare the outcome of tubular stomach and cervical esophagus laminated anastomosis and mechanical anastomosis. Methods A total of 128 patients with middle and upper esophageal cancer in our hospital from January 2013 to January 2016 were randomly divided into two groups, 64 patients in each group and all patients underwent esophagectomy. In the group A, there were 46 males and 18 females with age of 40–75 years, treated with tubular stomach and cervical esophagus layered anastomosis. There were 51 males and 13 females with age of 43–71 years in the group B receiving mechanical anastomosis. We observed the short-term and long-term efficacy as well as complications. Results In the group A, there was cervical anastomotic fistula in 1 patient, anastomotic stenosis in 2 patients and reflux esophagitis in 12 patients. In the group B, 1 patient suffered chylothorax, 8 patients cervical anastomotic fistula, 4 patients anastomotic stenosis and 14 patients reflux esophagitis. Conclusion Layered anastomosis can effectively reduce the incidence of anastomotic fistula and stenosis. Tubular stomach can effectively prevent and reduce the reflux esophagitis, and the high long-term quality of life will be achieved after the operation.
Objective To introduce a simple preoperative risk score for esophageal cancer (PRSEC) and its relationship with the prognosis of patients who underwent resection of esophageal carcinoma. Methods We retrospectively analyzed the clinical data of 498 patients receiving resection of esophageal carcinoma between 2005 and 2015 in our hospital. They were divided into three groups (PRSEC1, PRSEC2 and PRSEC3 groups) according to the results of PRSEC (revised cardiac risk index, model for end-stage liver disease score and pulmonary function test). Their overall survival (OS) and disease-free survival (DFS) were measured to find the relationship between the PRSEC and prognosis of patients. Results The mortality, morbidity, DFS and OS were correlative with the PRSEC. Therefore the PRSEC can be used to predict the short-term outcome. The patients with score 2 or 3 had higher risk of mortality and morbidity than those with score 1. In addition, the DFS and OS of patients with higher score were shorter (P<0.001). Conclusion The PRSEC is easy and efficient and can predict the morbidity, mortality, and long-term outcomes for the patients with resection of esophageal carcinoma.
Objective To systematically review the prognostic significance of extranodal extension in gastric cancer, esophageal cancer and gastroesophageal junction cancer. Methods We searched EMbase, The Cochrane Library (Issue 9, 2016), PubMed, CBM, CNKI, VIP and WanFang Data databases from inception to August 2016, to collect cohort studies about the prognostic significance of extranodal extension. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.2 software. Results A total of 16 studies involving 9 445 participants were included. The results of meta-analysis showed that for gastric cancer patients, the overall survival (OS) (HR=1.71, 95%CI 1.49 to 2.00,P<0.000 01), disease free survival (DFS) (HR=1.39, 95%CI 1.12 to 1.73,P=0.003) and cancer specific survival (HR=1.52, 95%CI 1.18 to 1.96,P=0.001) in ENE(+) group were lower than ENE(–) group. For esophageal cancer and gastroesophageal junction cancer patients, the overall survival (OS) (HR=1.84, 95%CI 1.49 to 2.27,P<0.000 01), disease free survival (DFS) (HR=2.18, 95%CI 1.70 to 2.81,P<0.000 01) and cancer specific survival (HR=1.73, 95%CI 1.19 to 2.52,P=0.004) in ENE(+) group were lower than ENE(–) group. Conclusion Current evidence indicates that ENE(+) was correlated with a poor prognosis in gastric cancer, esophageal cancer and gastroesophageal junction cancer patients. Due to the quantity and quality limitations of included studies, more high quality cohort studies are needed to verify the above conclusions.
Lymphatic metastasis of esophageal cancer is one of the main ways of esophageal cancer metastasis and it is as well one of the most important factors influencing the prognosis of esophageal cancer patients. Compared to intravenous administration of chemotherapy, local chemotherapy has the less toxicity and less systemic side effects. Nano carbon is a safe and effective carrier for intraoperative lymphatic chemotherapy. It plays an important role in tracing and targeting lymph node during the lymphatic chemotherapy. Lymphatic chemotherapy can induce tumor into necrosis and apoptosis. For esophageal cancer, lymphatic chemotherapy is also to be proved to improve the rate of lymph node dissection and the number of metastatic lymph nodes, decrease tumor size, improve the quality of life and survival rate. In conclusion, lymphatic chemotherapy can be considered an assistant therapy to eliminate the tumor cell in lymph nodes and micrometastatic foci. In this review, the metastatic characteristic of esophageal cancer, the significance, mechanism and application of lymphatic chemotherapy carried by nano carbon are summarized.
Objective To analyze the clinical characteristics of patients treated with esophagectomy following endoscopic submucosal dissection (ESD) for early stage esophageal cancer or precancerosis and the reasons for esophagectomy. Methods We retrospectively analyzed the clinical data of 57 patients who were treated with esophagectomy following ESD in West China Hospital and Shanxian Hygeia Hospital from January 2012 through October 2016. There were 42 males and 15 females at age of 65.4 (52–77) years. There were 15 patients of upper thoracic lesions, the middle thoracic lesions in 34 patients, and the lower thoracic lesions in 8 patients. Results The reasons for esophagectomy included 3 patients with residual tumor, 8 patients with local recurrence, 37 patients with esophageal stricture, and 9 patients with dysphagia, although the diameter was larger than 1.0 cm. The pathology after esophagectomy revealed that tumor was found in 16 patients, including 3 patients with residual tumor and 8 with recurrent tumor confirmed before esophagectomy, and 5 patients with new-found recurrent tumor. Conclusion In the treatment of early stage esophageal cancer or precancerosis, the major reasons for esophagectomy following ESD include esophageal stricture, abnormal esophageal dynamics, local residual or recurrence.
Objective To investigate the efficacy of Docetaxel injection and Capecitabine tablets combined with Oxaliplatin injection in chemotherapy for patients after esophageal cancer surgery. Methods We retrospectively analyzed the clinical data of 101 patients with esophageal cancer who underwent radical surgery from June 2010 to December 2012, including 58 males and 43 females. According to the different treatment methods they were divided into a study group (58 patients, 32 males and 26 females, postoperatively receiving Docetaxel injection, Capecitabine tablets, Oxaliplatin injection and chemotherapy) and a control group (43 patients, 26 males and 17 females, taking Docetaxel injection and Capecitabine tablets for 4 consecutive courses). We compared the difference in the outcomes between the two groups. Results There was no significant difference in the level of serum anticancer antigen (CEA), carbohydrate antigen 125 (CA125), carbohydrate antigen 199 (CA199) and squamous cell carcinoma antigen (SCC) before chemotherapy between two groups (P>0.05). After chemotherapy, the level of serum CEA, CA125, CA199, SCC in the study group was significantly lower than that in the control group (P<0.05). The 1-year survival rate of the study group was 92.59% and the 2-year survival rate was 70.37%, which were not significantly different from those of the control group (P>0.05). The 3-year survival rate of the study group was significantly higher than that of the control group (57.41 %vs. 32.43%, P<0.05). The mean survival time of the study group was longer than that of the control group (31 monthsvs. 22 months, P=0.001). Conclusion Docetaxel injection and Capecitabine tablets combined with Oxaliplatin injection for the treatment of esophageal cancer surgery can significantly reduce levels of tumor markers in serum after esophageal cancer surgery, and is favorable for the long-term survival of patients, but adverse reactions should be noted.
Objective To assess the outcome of harmonic scalpel (HS) in esophageal cancer surgery and to provide evidence for the role of HS in the enhanced recovery after surgery (ERAS) and short-term prognosis after esophageal cancer surgery. Methods We collected the clinical data of 81 esophageal cancer patients receiving surgery by HS between January 1 and December 31, 2016 and successfully followed up in our department. There were 67 males and 14 females with an average age of 64.07±7.52 years. Sweet approach was adopted in 16 patients, Ivor-Lewis approach in 23 and McKeown approach in 40. Intrathoracic anastomosis was completed in 41 patients and cervical anastomosis in 40. The length of total hospital stay and postoperative hospital stay, operation time, intraoperative blood loss, duration and volume of thoracic drainage and perioperative complications were recorded and compared in patients with different surgical approaches and anastomosis sites. Results For these 81 patients, the operation time was 276.7±70.4 min, and the intraoperative blood loss was 115.9±69.7 ml. The postoperative duration of thoracic drainage, postoperative complication rate and the drainage volume were 12.3±5.3 d, 35.80% and 1 411.9±1 199.5 ml, respectively. During the follow-up, 15 patients died and the cumulative survival rate was 81.48%. There was no obvious HS-related complication. The operation time of Sweet approach was shorter than that of Ivor-Lewis or McKeown approach (P=0.012) and the dissected lymph nodes were less in Sweet approach (P=0.035). There was no significant difference in perioperative indexes and postoperative short-term prognosis between intrathoracic anastomosis and cervical anastomosis. Conclusion HS is widely used in the surgery for esophageal cancer with safety and effectiveness, which is worthy of clinical application.
