To evaluate the present status of treatment of chronic pancreatitis, 116 consecutive patients with chronic pancreatitis during the last decade (1986～1996) have been surveyed retrospectively. The clinical date has been analized statisticaly. Etiology: biliogenic 56 cases (48.3%), alcoholic 17 (14.6%), idiopathic 34 (29.3%) and other 9 cases (7.8%). Better result was achieved in surgical treatment group (81 cases) than in conservative group (35 cases), pain free: 65.5% vs 33.3%. The accumulated five-year survival rate was 56.3%, 92.2% and 78.1% in alcoholic, billiogenic and idiopathic type of chronic pancreatitis respectively. Morbidity and mortality of diarrhea and diabetes mellitus increased at followup. The authors conclude that the chronic pancreatitis patients associated with obstruction of biliopancreatic duct should undergo operation early and will ameliorate abdominal pain.
Objective To evaluate the long-term efficacy of extended and standard surgery for carcinoma of head of pancreas by using meta-analysis. Methods Related articls （1990-2012） were searched in Pubmed， WOS， Embase， WanFang， SinoMed， and CNKI. Study on quality of these literatures were evaluated by using the Jadad score. The patients with pancreatic head carcinoma underwent extended radical resection and standard radical resection were classified to treatment group and control group， respectively. The mortality， morbidity， and survival rates of 1-， 3-， and 5-year after operation in the two groups were evaluated by using meta-analysis. Results A total of 11 studies fitted the selection crit-eria， including 744 patients. Among them 357 cases were in standard radical resection group and 387 cases in the extended radical resection group. The results of meta-analysis showed that： ①The morbidity after operation did not significantly differed between the extended radical resection group and standard radical resection group （OR=1.360， 95% CI=0.990-1.870， P=0.050）. ②The mortality of the two groups did not significantly differed （OR=0.870， 95% CI=0.430-1.760，P=0.700）. ③There were no significant differences in survival rates of 1-， 3-， and 5-year between the two groups （OR=0.880， 95% CI=0.450-1.720， P=0.710；OR=0.940， 95% CI=0.590-1.480，P=0.710；OR=1.000， 95% CI=0.600-1.67， P=1.000）. Conclusion Compared with standard radical resection， extended radical resection can not improve the survival rates of 1-， 3-， and 5-year after operation， and can’t reduce the mortality and morbidity after operation
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 assess the value of precise hepatectomy in treatment of primary hepatocellular carcinoma. Methods Three-dimensional (3D) models from MR image were reconstructed by 3D-Doctor software in 32 patients with primary hepatocellular carcinoma scheduled for liver resection between July 2007 and Sept 2009. From these 3D models, the vena cava, portal vein, hepatic vein, and short hepatic vein images were reconstructed, total liver volume, tumor volume, functional liver volume and ratio of functional liver volume to standard liver volume (SFLVR) were calculated. The patients were followed-up for 1-27 months, with an average of 12 months. Results The anatomic detail of liver veins and its relationship with the tumor could be displayed clearly in liver 3D models. By the 3D models, total liver volume was calculated as （1 353±419）ml, tumor volume as （287±248） ml, functional liver volume as （830±289） ml, and SFLVR as （71±22）%. Of 32 patients with hepatocellular carcinoma, right hemihepatectomy was performed in 8 cases, left hemihepatectomy in 2, and segmental or limited resection in 22. All operations were completed successfully. Postoperative complications included pulmonary infection in 1 case, bile leak in 1, moderate ascites (500-3 000 ml) in 8, and massive ascites (gt;3 000 ml) in 2 including one patient developed hepatic failure. Six and 12-month survival rates were 100% and 87%. Three, 6, and 12-month disease-free survival rates were 78%, 72%, and 72%. Conclusions Precise hepatectomy technique provides an accurate picture of liver veins anatomy and its relationship with the tumor， and allows the procedure to be simulated preoperatively for adequate and safe hepatectomy.
ObjectiveTo analyze the short- and long-term therapeutic effects of heart transplantation in children. MethodsA retrospective study was conducted on recipients and donors who underwent heart transplantation at the 7th People’s Hospital of Zhengzhou from May 2018 to August 2023, analyzing their clinical characteristics, surgical data, postoperative complications, and survival rates. ResultsA total of 22 children underwent heart transplantation, including 14 males and 8 females, with a median age of 13.5 (10.0, 15.0) years and a median weight of 41.9 (30.5, 55.4) kg. The primary diseases included: dilated cardiomyopathy in 16 patients, hypertrophic cardiomyopathy in 1 patient, myocardial dysplasia in 3 patients, right ventricular dysplasia in 1 patient, and congenital heart disease with abnormal coronary artery origin in 1 patient. The median age of the donors was 21.0 (13.0, 29.0) years, and the median weight was 50.5 (47.3, 75.0) kg. The blood types of the donors and recipients were the same, with type A in 10 patients, type B in 5 patients, type O in 5 patients, and type AB in 2 patients. Before transplantation, all children had a New York Heart Association cardiac function grade Ⅳ, with 1 patient assisted by intra-aortic balloon pump (IABP), 3 patients assisted by extracorporeal membrane oxygenation (ECMO), 2 patients assisted by continuous renal replacement therapy (CRRT), and 2 patients on mechanical ventilation. Nine patients met the criteria for emergency child status allocation, and the panel reactive antibody level in the patients was<10%. The median cold ischemic time of the donor heart was 355.0 (262.0, 395.5) min, the median aortic cross-clamping time was 45.0 (38.3, 51.3) min, the median mechanical ventilation time was 22.5 (16.8, 52.5) h, the median postoperative hospital stay was 29.5 (20.0, 43.0) d, and the median intensive care unit stay was 6.0 (5.0, 8.3) d. After surgery, 4 patients were assisted by ECMO, 2 patients by CRRT, and 7 patients developed complications, including lung fungal infection in 6 patients, liver and kidney dysfunction in 1 patient, local wound non-union and mediastinal infection in 1 patient, and multiple organ failure in 1 patient. Kaplan-Meier curve analysis showed that the survival rates of children after surgery were 91.3% at 1 year and 3 years; the survival rates of adult heart transplant recipients at our center were 86.7% and 73.8% at 1 year and 3 years, respectively, indicating that the survival rate of children with heart transplantation was higher than that of adult patients. ConclusionHeart transplantation is an effective treatment for end-stage heart failure in children, and the short- and long-term survival rates of children with heart transplantation are superior to those of adults. There are still many difficulties to be solved in pediatric heart transplantation, requiring joint efforts from society and the medical community.
Objective To investigate the early diagnosis and treatment methods of primary duodenal papilla carcinoma. Methods The medical records of 54 patients with primary duodenal papilla adenocarcinoma underwent operation between January 2002 and December 2008 were reviewed. Results Thirty seven cases received fiberduodenoscopy and 35 cases received ERCP, and the accuracy of them were both 100%. Forty four patients received duodenopancreatectomy and 10 patients received jaundice-reducing operation. The 1-, 3-, and 5-year cumulation survival rate was 68%, 50%, and 29%, respectively. Conclusions Fiberduodenoscopy and ERCP are the effective diagnostic methods for duodenal papilla carcinoma. Early diagnosis and early rational radical operation are essential for successful treatment of duodenal papilla carcinoma.
Abstract: Objective [WTBZ]To evaluate the longterm effects of preoperative glucocorticoid treatment on postoperative complications and survival rates for patients receiving cardiac surgery. Methods [WTBZ] We selected 57 patients including 22 males and 35 females at an average age of 52.3±11.2 years in the First Hospital of China Medical University who took steroids for a long time because of various combined diseases from September 2002 to August 2009 in the trial group, and we chose another 171 patients including 62 males and 109 females at an average age of 53.6±9.2 years who were hospitalized at the same time and had comparative basic features in the control group. There was no statistical difference between the two groups in age, gender, and organ function. Different kinds of surgeries including coronary artery bypass grafting, heart valvuloplasty or valve replacement, coronary artery bypass grafting combined with heart valve replacement, and congenital heart disease surgery were performed on the patients. The proportion of surgeries carried out was similar in the two groups. Postoperative complications were compared between the two groups, and survival rates at the end of 6 months and one year followup were observed. Results [WTBZ]There was no statistical difference between the two groups in complications with respect to cardiopulmonary bypass (CPB) time (t=1.27, Pgt;0.05), reoperation for excessive postoperative bleeding (χ2=0.03, P=0.87), sternal and mediastinal infection (χ2=0.04, P=0.84), stroke (χ2=0.07, P=0.79), and gastrointestinal tract complications (χ2=2.89, P=0.09). The incidence of ventricular arrhythmia and requirement for intraaortic balloon pump in the trial group was higher, but no statistical difference was detected (χ2=2.24, P=0.13; χ2=2.20, P=0.14, respectively). Patients in the trial group were more likely to require prolonged ventilation (t=2.32, Plt;0.05), had higher rate of atrial fibrillation (χ2=4.09, P=0.04), and higher inhospital mortality (χ2=5.35, P=0.02). The sixmonth and oneyear survival rates were 0.79±0.10 and 0.73±0.12, respectively for the trial group, 0.94±0.09 and 0.86±0.10, respectively for the control group. Conclusion Longterm steroid treatment leads to higher atrial fibrillation incidence, longer ventilation time and increases the mortality rate following cardiac surgery.
Objective To investigate the clinical features of non-small cell lung cancer (NSCLC) patients with long-term survival and the related factors for treatment. Methods A retrospective analysis of clinical features, treatment factors, and survival was performed for 963 patients with pathologically confirmed stage Ⅳ NSCLC between January 2010 and December 2015 from Department of Thoracic Oncology, West China Hospital, Sichuan University. Results The median overall survival (OS) of the 963 patients was 20.8 months, and the 1-, 3-, 5-, and 7-year survival rates were 72.0%, 21.4%, 15.2%, and 4.8%, respectively. There were 81 patients in the long-term survival group (OS>60 months) and 882 in the non-long-term survival group (OS<60 months). Previous surgery, thoracic radiotherapy and epidermal growth factor receptor (EGFR) gene positive significantly increased the 5-year actual survival rate, reducing the risk of death by 62.0%, 58.8%, and 58.1%, respectively. Compared with the non-long-term survival group, more patients in the long-term survival group received two or more means of treatment including surgery, thoracic radiotherapy, and targeted therapy (28.4% vs. 11.6%, P<0.001) and more patients benefited from fourth- or further-line treatment (24.7%vs. 11.1%, P<0.001). Cox multivariate regression analysis indicated that performance status [hazard ratio (HR)=1.388, 95% confidence interval (CI) (1.199, 1.608), P<0.001] , N stage [HR=1.160, 95%CI (1.058, 1.272), P=0.002] , EGFR gene status [HR=0.588, 95%CI (0.469, 0.738), P<0.001] , previous surgery [HR=0.626, 95%CI (0.471, 0.832), P=0.001] , and thoracic radiotherapy [HR=0.592, 95%CI (0.480, 0.730), P<0.001] were independent prognostic factors of OS. Conclusions Good performance status, early N staging, EGFR mutation, previous surgery, and thoracic radiotherapy are important prognostic factors affecting the survival of advanced NSCLC patients. Long-term survival benefits from combined treatment and effective further-line therapies.
