Objective To use a meta-analysis method to establish quantitatively the association between the HER-2/neu gene amplification/enhanced protein expression status and the 5-year post-operative survival rate or median survival time in women with epithelial ovarian carcinoma. Methods We searched and screened Chinese and English literature published since 1989 to collect all retrospective cohort studies on the prognostic significance of HER-2/neu status in this population. The survival data were analyzed using Ludwig’s centered signed rank and the DerSimonian-Laird method. Results In total, 25 studies involving 3 251 patients were included. HER-2/neu was positive in 27.1% (95%CI 0 to 54.8%) of patients, which was not related to the pathological stage, type or grade of epithelial ovarian carcinoma. In HER-2/neu positive cases, the median survival time was shortened by 0.65 years, and the 5-year survival rate was lowered. The hazard ratio (HR) for mortality was 1.22 (95%C 1.09 to 1.36). By subgroup analysis, HER-2/neu protein expression was found to be most significant in prognostic assessment. Patients with a b positive value of HER-2/neu had an increased HR for the 5-year survival; and platinum-based chemotherapy was demonstrated to be less effective in HER-2/neu positive ovarian carcinoma. Conclusion In gynecological oncology, it is reasonable to measure HER-2/neu as a routine pathological marker to predict a patient’s prognosis and to determine the most appropriate adjuvant chemotherapy regimen.
Objective To investigate the prognostic factors related to long-term survival after gastrectomy. Methods A total of 351 patients with gastric cancer who underwent gastrectomy were successfully followed-up in our hospital had been selected from January 2004 to December 2009. The clinicopathological and follow-up data were studied by univariate and multivariate analysis. Results The age, location of tumors, T stage, N stage, TNM stage, and differentiation were related with postoperative survival of patients with gastric cancer by using univariate analysis（P＜0.05）. By using multivariate analysis, location of tumors, T stage, N stage, and chemotherapy were independent prognostic factors（P＜0.05）. Conclusions Location of tumors, depth of tumor invation, lymph node metastasis, and chem-otherapy were independent prognostic factors for gastric cancer patients who underwent gastrectomy. Chemotherapy after surgery could increase the survival rate of gastric cancer patients with lymph node metastasis or in TNM stage Ⅲ.
Objective To investigate whether predicted heart mass (PHM) ratio can predict the prognosis of adult heart transplant patients. MethodsClinical data of 309 heart transplant patients in the 7th People’s Hospital of Zhengzhou from May 2018 to July 2024 were retrospectively analysed. The cut-off value of the PHM ratio was calculated, grouping was conducted according to the cut-off value, and the baseline data and prognosis data of the two groups were compared. ResultsA total of 249 adult heart transplant recipients were included in this study according to the inclusion and exclusion criteria. Cut-off value of the PHM ratio was –0.01. There were 63 patients in the PHM ratio>–0.01 group and 186 patients in the PHM ratio≤–0.01 group. The results of univariate analysis revealed that there were statistically significant differences between the two groups in terms of recipient gender, age, physical indicators, donor gender, and several other aspects (all P<0.05). There was no statistical difference in primary disease, recipient blood type, infectious disease, emergency status, preoperative intra-aortic balloon pump (IABP), preoperative extracorporeal membrane oxygenation (ECMO), preoperative continuous renal replacement therapy, preoperative mechanical ventilation, and preoperative blood creatinine (P>0.05). In terms of prognosis, there were statistical differences between the two groups in postoperative ECMO (P=0.048), and postoperative IABP (P=0.027). Survival rate was significantly lower in the PHM ratio≤–0.01 group than that in the PHM ratio>–0.01 group (HR=1.748 0, 95%CI 1.007 0-3.035 0, P=0.047). Multifactorial Cox regression showed that PHM ratio was significantly associated with survival after heart transplantation (HR=0.000 3, 95%CI 0.000 1-0.001 2, P<0.001); recipient sex, donor sex, donor BMI, donor BSA, recipient BMI, recipient BSA did not significantly correlate with post cardiac transplantation survival. ConclusionPHM ratios can predict the prognosis of adult heart transplantation, and donor hearts with PHM ratios>–0.01 should be selected as much as possible when performing heart donor evaluation.
ObjectiveTo compare the clinical efficacy of modified Ivor-Lewis esophagectomy, which preserves azygos vein, thoracic duct and peripheral tissues, and classic Ivor-Lewis esophagectomy, which resects these tissues, in the treatment of esophageal cancer, so as to evaluate whether it is necessary to resect azygos vein, thoracic duct and peripheral tissues in esophagectomy for esophageal cancer.MethodsPatients scheduled for surgical treatment of thoracic esophageal cancer in Department of Thoracic Surgery of Sichuan Cancer Hospital from June 2011 to June 2013 were randomly assigned to the retention group and the resection group, each including 100 patients. The retention group included 87 males and 13 females with an average age of 60.53±7.72 years. In the resection group, there were 80 males and 20 females with an average age of 60.69±7.69 years. Patients in the two groups were compared for the duration of surgery, intraoperative blood loss, postoperative thoracic drainage volume, postoperative complications, and number of dissected lymph nodes, etc. Postoperative relapse and survival rates at 1, 3 and 5 years postoperatively were also followed up and compared for patients in the two groups.ResultsThere was no statistical difference between the two groups in general patient characteristics, number of dissected lymph nodes, or postoperative pathological stage, etc. (P>0.05). Compared to the resection group, there were shorter duration of surgery, less intraoperative blood loss, and less thoracic drainage volume in the first 3 days following surgery in the retention group, with statistical differences (P<0.05). There was no statistical difference between the two groups in type or site of relapse or metastasis (P>0.05). The survival rates at 1, 3, and 5 years postoperatively was 78.7% vs. 81.3%, 39.4% vs. 37.5%, and 23.4% vs. 17.7%, respectively, in the retention group and the resection group, with no statistical difference (P>0.05).ConclusionModified Ivor-Lewis esophagectomy preserving azygos vein, thoracic duct and peripheral tissues could reduce surgical trauma, would not increase postoperative relapse or metastasis, and could produce long-term efficacy comparable to that of extended resection.
Objective To systematically evaluate the efficacy and safety of single and bilateral lung transplantation in the treatment of end-stage chronic obstructive pulmonary disease (COPD). Methods Chinese and English databases were searched by computer, including PubMed, Web of Science, The Cochrane Library, EMbase, CNKI, Wanfang database, VIP database and CBM. Case-control studies on single lung transplantation or bilateral lung transplantation for COPD were collected from the inception to July 31, 2022. We evaluated the quality of the literature via Newcastle-Ottawa Scale (NOS). All results were analyzed using Review Manager V5.3 and STATA 17.0. Results A total of 8 studies were included covering 14076 patients, including 8326 patients in the single lung transplantation group and 5750 patients in the bilateral lung transplantation group. NOS scores were≥6 points. The results of meta-analysis showed that there was no statistical difference in the postoperative 1-year survival between the two groups (P=0.070). The 2-year survival rate (P=0.002), 3-year survival rate (P<0.001), 5-year survival rate (P<0.001), overall survival rate (P＜0.001), postoperative forced expiratory volume in one second/predicted value (P<0.001), postoperative forced vital capacity (P<0.001), and postoperative 6-minute walking distance (P=0.002) were lower or shorter than those in the bilateral lung transplantation group, the postoperative intubation time (P=0.030) was longer than that in the bilateral lung transplantation group. Bilateral lung transplantation group showed better surgical results. There was no statistical difference in the mortality, obliterative bronchiolitis, length of hospitalization, primary graft dysfunction, or postoperative adverse events (P>0.05). Conclusion Bilateral lung transplantation is associated with better long-term survival and postoperative lung function compared with single lung transplantation. In-hospital mortality and postoperative complications are similar between them.
ObjectiveTo investigate the short-term follow-up results of inflatable mediastinoscopy combined with laparoscopy in the treatment of esophageal cancer.MethodsClinical data of 102 patients with esophageal cancer who underwent minimally invasive esophagectomy were enrolled in our hospital from January 2017 to January 2019. Patients were divided into two groups according to different surgical methods, including a single-port inflatable mediastinoscopy combined with laparoscopy group (group A, n=59, 53 males and 6 females, aged 63.3±7.6 years, ranging from 45 to 75 years) and a video-assisted thoracoscopy combined with laparoscopy group (group B, n=43, 35 males and 8 females, aged 66.7±6.7 years, ranging from 50-82 years). The short-term follow-up results of the two groups were compared.ResultsCompared with the group A, the rate of postoperative pulmonary complication of the group B was significantly lower (18.64% vs. 4.65%, P<0.05). There was no significant difference between the two groups in other postoperative complications (P>0.05). The 6-month, 1-year, and 2-year survival rates were 96.61%, 89.83%, and 73.33%, respectively in the group A, and were 95.35%, 93.02%, and 79.17%, respectively in the group B. There was no significant difference in short-term survival rate after operation (P>0.05).ConclusionIn the treatment of esophageal cancer, the incidence of pulmonary complications of inflatable mediastinoscopy combined with laparoscopy is lower than that of traditional video-assisted thoracoscopy combined with laparoscopy, and there is no significant difference in other postoperative complications or short-term survival rate between the two methods. Inflatable mediastinoscopy combined with laparoscopy for radical esophageal cancer is a relatively safe surgical method with good short-term curative effects, and long-term curative effects need to be further tested.
Objective Through conducting a meta-analysis using the methodology of Cochrane review, to assess the effectiveness and safety of graft-versus-host disease (GVHD) prophylaxis with antithymocyte globulins (ATGs) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Such databases as PubMed (1966 to March 2011), EMbase (1974 to March 2011), the Science Citation Index databases (1900 to March 2011), The Cochrane Library (1996 to March 2011), CBMdisc (1978 to March 2011), and CNKI (1979 to March 2011) were electronical1y searched. The references of all identified studies were retrieved for collecting more randomized controlled trials (RCTs) and non-RCTs. Two reviewers independently screened the trials according to inclusion and exclusion criteria, abstracted the data, and assessed the methodology quality of the included studies. Meta-analyses were performed using RevMan 5.0.2 software. Results Thirteen clinical trials were included, of which 2 were RCTs involving 310 patients and the other 11 were non-RCTs involving 1480 patients. The results of meta-analyses showed that compared with the Non-ATG group, the pooled risk ratio (RR) and 95%CI of the ATG group in acute GVHD II-IV incidence rate, acute GVHD III-IV incidence rate, chronic GVHD (limited plus extensive) incidence rate, chronic GVHD (extensive) incidence rate, overall survival (OS) rate, non-relapse mortality (NRM) rate, and relapse rate were 0.77 (0.67, 0.87), 0.54 (0.44, 0.68), 0.58 (0.51, 0.65), 0.35 (0.26, 0.46), 1.14 (1.04, 1.25), 0.81 (0.69, 0.93), and 1.24 (0.98, 1.57), respectively. Conclusion The addition of ATGs to GVHD prophylaxis can reduce the incidence of acute and chronic GVHD, decrease NRM, and increase OS, but has no obvious interference with relapse rate.
The surgical treatment of acute aortic dissection is difficult, and the mortality is associated with anastomosis site complications. Therefore, it is essential to make sure the end-to-end anastomosis safe and avoid bleeding. The methods of anastomosis include: direct anastomosis, adventitial inversion technique and sandwich technique. The latter two methods are both effective in hemostasis and reducing the postoperative complications. According to the recent literatures, the adventitial inversion technique may facilitate thrombotic closure of the false lumen in acute type A aortic dissection management and increase the long-term survival of the patients. This review introduces 2 modified methods of anastomosis as well, and summarizes clinical outcomes of different end-to-end anastomotic methods for surgical treatment of acute Stanford type A aortic dissection, in order to recommend the most proper method of end-to-end anastomosis.
