ABSTRACT
@#Objective To investigate the short-term therapeutic effect of neoadjuvant immunotherapy combined with chemotherapy in the locally advanced esophageal squamous cell carcinoma. Methods The clinical data of patients with esophageal squamous cell carcinoma treated with neoadjuvant treatment in Gaozhou People's Hospital from August 2019 to October 2020 were retrospectively analyzed. According to the different treatments, the patients were divided into two groups: a neoadjuvant immunotherapy combined with chemotherapy group (NIC group) and a neoadjuvant chemoradiotherapy group (NC group). The baseline data, incidence of adverse events during treatment, perioperative indicators, postoperative pathological remission rate and incidence of postoperative complications were compared between the two groups. Results Totally 33 patients were enrolled, including 15 males and 18 females, with an average age of 62.37±7.99 years. There were 17 patients in the NIC group and 16 patients in the NC group. In the NIC group, the carcinoma was mainly located in the middle and lower esophagus, with 5 paitents in stage Ⅱ, 9 patients in stage Ⅲ, and 3 patients in stage Ⅳa. In the NC group, the carcinoma was mainly located in the upper-middle esophagus, with 1 patient in stage Ⅱ and 15 patients in stage Ⅲ. During the neoadjuvant treatment, there was no significant difference in the occurrence of bone marrow suppression or gastrointestinal reactions between the two groups (P>0.05). There were 4 immune-related rashes in the NIC group and 1 esophageal perforation in the NC group. Fourteen (82.35%) patients in the NIC group and 12 (75.00%) patients in the NC group completed the operation on schedule. The postoperative ICU stay time and chest tube indwelling time in the NIC group were shorter than those in the NC group (P<0.05). There were 5 patients of complete remission in the NIC group, and 6 patients in the NC group. There was no significant difference in the pathological regression grade or residual tumor cells between the two groups (P>0.05). There was no significant difference in the incidence of anastomotic fistula, thoracic gastric fistula, bronchial mediastinal fistula, abdominal distension, pulmonary infection, stroke, or hoarseness during the perioperative period between the two groups of patients who completed the operation (P>0.05). In the NC group, 2 patients died during the perioperative period because of thoracic gastric fistula complicated by severe infection. Conclusion Neoadjuvant immunotherapy combined with chemotherapy dose not significantly increase the occurrence of adverse events and shows a good rate of pathological remission, which indicates that the neoadjuvant immunotherapy combined with chemotherapy is a safe, feasible and potential new treatment model.
ABSTRACT
Objective To explore the feasibility,necessity and the skill of total mesoesophageal excision (TME ) during thoracoscopy combined with laparoscopy in radical resection of esophageal carcinoma.Methods 69 patients with esophageal carcinoma were divided into the TME group(40 cases)and the thoracotomy with triple incisions group(29 cases)according to the admission sequence.The operation time,intraoperative blood loss,total lymph nodes removed,postoperative complication rate and disease -free survival were compared between the two groups.Results The operation time of TME group was (182.85 ±26.73)min,which was significantly shorter than (295.71 ±19.50)min of the thoracotomy group (t=-19.301,P0.05 ).The disease-free survival period in TME group was (14.78 ±2.14)months,which in the thoracotomy group was (13.10 ±4.09)months,the difference was significant (t=2.200,P<0.05).Conclusion TME is safe and feasible during thoracoscopy combined with laparos-copy in radical resection of esophageal carcinoma.TME is better in improving the regional control in esophageal carci-noma.
ABSTRACT
Objective To examine the practicability and security of the LigaSureTM vessel-sealing system in radical gastrcctomy.Methods Seventy patients of stage Ⅰ～Ⅲ gastric cancer undergone radical gastrectomy were analyzed retrospectively.Thirty-five radical gastrectomy were performed with LigaSureTM vessel-sealing system,the other 35 eases were performed without LigaSureTM.The operative duration,volume of intraoperative hemorrhage,and postoperative complications were analyzed.Results There were significant difference in both operative duration[(159.9±24.7)min vs(172.6±23.7)min,P＜0.05]and volume of intraoperative hemorrhage[(335.7±40.3)ml vs(371.7±43.2)ml,P＜0.01].There was no significant difference in the postoperative complications between LigaSureTM group and conventional method group.All patients recovered without severe postoperative complications.Conclusion Radical resection of gastric cancer using LigaSureTM instead of conventional hand tie method appears to he shorten operative duration,decreased volume of intraoperative hemorrhage.And the technique is convenient and safe.
ABSTRACT
Objective To investigate the optimal operative approach for esophageal and cardiac carcinoma,in order to obtain favorable exposure and to diminish trauma.Methods A method of median-rib-Section were performed in 207 cases of esophageal and cardiac carcinoma:the 6th and 7th ribs were cut intermediately,then we peeled and cut the rib periosteum.stretching the costal interspace with a prop until the exposure was optimal.Items including traumatic degree,exposure extend and conditions of thoracic cavity closure were compared with that of traditional antemposterior-rib-section method.Results The exposure result was similar in the two methods,but the traumatic de-grce WaS less when anteroposterior-rib·section was applied,due to its avoiding cutting intercostal muscles which caused more blood loss.The median-rib-section method led to more satisfactory anatomy paratope and external appearance,less trawma and incision pain.Conclusion The method of median-rib-section is worthy of generalization because of its satisfactory exposure,less trauma,better paratope and absence of postoperative costal malformation.
ABSTRACT
Objective The purpose of this study was to develop a database program based on Microsoft Access 2003 for patients with breast cancer to save and manage clinical data.This makes it easier to analyze data of the database.Methods A total of 1177 cases with breast cancer who were performed surgical treatment from December 1998 to June 2007,the clinical data collection which included regular fouow-up data of these patients after therapy,the database was designed by using Microsoft Access 2003 included the creation of tables,forms and queries according to the therapy guidelines for breast cancer.Results The clinical data for patients with breast cancer can be stored in an Access database that is both user-friendly with reliable data administration and that can be shared in network,and it is capable of recording regular updated data.Conclusion This program will not only convenient for researchers to statistic and analyze their outcome data,but also for minimizing data entry errors and reducing the time spent on data query.
