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.
ObjectiveTo assess the long-term effectiveness and safety of autologous bone marrow mononuclear cells (BM-MNC) transplantation in the treatment of critical diabetic lower arteriosclerosis obliterans (ASO). MethodsBetween January 2007 and January 2010, 61 patients with critical diabetic lower ASO were treated with standard medical therapies in 29 cases (control group) or with standard medical therapies and autologous BM-MNC transplantation in 32 cases (treatment group). There was no significant difference in gender, age, disease duration, Fontatine stage, glucose (GLU), triglyceride (TG), total cholesterol (CHOL), low-density lipoprotein-cholesterol (LDL-C), hemoglobin A1c (HbA1c), systolic blood pressure (SBP), and diastolic blood pressure (DBP) between 2 groups (P>0.05). The endpoints were overall survival (OS) and amputation-free survival (AFS). The risk indexes for ASO were observed and compared between 2 groups before and after treatments. ResultsThe patients were followed up 2-36 months, and no malignant tumor occurred. The OS rate, OS time, AFS rate, and AFS time were 82.76% (24/29), (32.31±9.08) months, 37.50% (9/24), and (21.28±13.35) months in the control group and were 78.13% (25/32), (32.47±6.96) months, 68.00% (17/25), and (28.38±9.48) months in the treatment group;all indexes showed no significant differences (P>0.05). OS rate, OS time, AFS rate, and AFS time showed no significant differences between 2 groups at the other time (P>0.05) except AFS time at 1 year, which was significantly short in the control group than the treatment group (t=2.806, P=0.007). At the endpoint of follow-up, the indexes of GLU, TG, CHOL, LDL-C, HbA1c, SBP, and DBP showed no significant differences between before and after treatments and between 2 groups (P>0.05) in 49 survival patients (24 in control group and 25 in treatment group). ConclusionAutologous BM-MNC transplantation is safe and effective in the treatment of critical diabetic lower ASO, which can significantly improve AFS rate and prolong AFS time with no risks.
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 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.
ObjectiveTo investigate the impact of primary tumor site on prognosis of colorectal cancer after radical resection in different stages.MethodsFour hundreds and twenty patients with colorectal cancer in our hospital from Jan. 2008 to Dec. 2016 were selected as study subjects, all patients were confirmed by pathology. According to the location of colorectal cancer, the patients were divided into rectum group (n=220), left colon group (n=105) and right colon group (n=95). The difference of clinicopathological features of patients with different group were compared. The risk factors affecting the prognosis of colorectal cancer patients were analyzed by single factor and multi factor unconditional Cox regression analysis, and the survival curve was drawn by Kaplan-Meier method, and the difference test was carried out by log-rank method.ResultsThere were no significant differences between the three groups in age, BMI, smoking history, alcohol history, family history, vascular tumor thrombus, N staging, tumor diameter, nerve invasion and cancer nodule (P>0.05). There were significant differences in sex, pathological type, anterior intestinal obstruction, TNM staging, T staging and M staging (P<0.05). The results of single factor Cox regression analysis showed that sex, pathological type, anterior intestinal obstruction, TNM staging, T staging, M staging, primary tumor site, nerve invasion and cancer nodule were the risk factors for the prognosis of the patients (P<0.05). Multivariate Cox regression analysis showed that TNM staging, location of primary tumor and nerve invasion were risk factors affecting prognosis of patients (P<0.05). The total 5-year survival rate of the rectal group was 80.45% (177/220), the total 5-year survival rate of the left hemicolon group was 67.62% (71/105), and the total 5-year survival rate of the right hemicolon group was 68.42% (65/95). The survival curves of Kaplan-Meier showed that the difference between the three groups was statistically significant (P<0.05).ConclusonsThe 5-year survival rate of patients with rectal cancer is significantly higher than that of patients with left colon cancer and right colon cancer. For patients with different stage of colorectal cancer after radical resection, the prognosis of colorectal cancer can be predicted by the location of primary tumor.
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.
ObjectiveTo compare the 5-year survival rates between two different follow-up patterns of postoperative stage Ⅰ-ⅢA non-small cell lung cancer (NSCLC) patients.MethodsPathological stage Ⅰ-ⅢA NSCLC 11 958 patients who underwent surgical resection and received follow-up within 6 months after initial diagnosis through telephone follow-up system were included in nine hospitals from July 2014 to July 2020. The patients were divided into two groups including a proactive follow-up group (n=3 825) and a passive follow-up group (n=8133) according to the way of following-up. There were 6 939 males and 5 019 females aged 59.8±9.5 years. The Kaplan-Meier and Cox proportional hazards regression model were used.ResultsThe median follow-up frequency was 8.0 times in the proactive follow-up group and 7.0 times in the passive follow-up group. The median call duration was 3.77 minutes in the proactive follow-up group and 3.58 minutes in the passive follow-up group. The 5-year survival rate was 81.8% and 74.2% (HR=0.60, 95CI 0.53-0.67, P<0.001) in the proactive follow-up group and the passive follow-up group, respectively. Multivariate analysis showed that follow-up pattern, age, gender and operation mode were independent prognostic factors, and the results were consistent in all subgroups stratified by clinical stages.ConclusionThe proactive follow-up leads to better overall survival for resected stage Ⅰ-ⅢA NSCLC patients, especially in the stage ⅢA.
ObjectiveTo evaluate the effectiveness of preoperative immunosuppressive therapy combined with surgical intervention. MethodsA retrospective study was conducted on Behçet's disease patients who underwent cardiac surgery at Guangdong Provincial People's Hospital from 2012 to 2021. Patients were divided into immunosuppressive group and non-immunosuppressive group based on whether they received immunosuppressive therapy before surgery. The complications and long-term survival rates of the two groups were analyzed. ResultsA total of 28 patients were included, among which 2 patients underwent reoperation, a total of 30 surgeries were performed, including 16 males (53.3%), and the confirmed age was 37 (31, 45) years old. There were 15 surgeries in the immunosuppressive group and 15 surgeries in the non-immunosuppressive group. Compared with the non-immunosuppressive group, the incidence of complications during hospitalization in the immunosuppressive group was lower (13.3% vs. 53.3%, P=0.008). One patient died in hospital, and the rest were discharged and followed up, with a median follow-up time of 38.7 (15.1, 57.3) months, and there was no statistically significant difference in long-term survival rate between the two groups (26.7% vs. 6.7%, P=0.158). There was no statistically significant difference in the cumulative incidence of complications one month (20% vs. 53%, P=0.058) and one year (27% vs. 60%, P=0.065) after surgery between the immunosuppressive group and the non-immunosuppressive group, but there was a statistically significant difference in the cumulative incidence of complications three years after surgery (47% vs. 92%, P=0.002). ConclusionSurgical treatment can save lives in Behçet's disease patients with cardiovascular diseases, but the incidence of postoperative complications is high. Timely use of immunosuppressants before cardiovascular surgery can reduce the incidence of postoperative complications.
ObjectiveTo compare the long-term outcomes of laparoscopic hepatectomy (LH) and open hepatectomy (OH) in the treatment of hepatocellular carcinoma (HCC), and to discuss the recurrence patterns of HCC after surgery. MethodsPatients with HCC who underwent hepatectomy and met inclusion and exclusion criteria from January 2015 to December 2018 were retrospectively enrolled, then were divided into LH and OH groups according to surgical methods. The results of HCC recurrence after LH and OH were compared after 1∶1 propensity score matching between the two groups. The potential risk factors for recurrence were assessed by Cox proportional hazards regression and a nomogram was constructed. ResultsA total of 977 patients with HCC who underwent hepatectomy were enrolled. Of these, 385 underwent LH and 592 underwent OH. After 1∶1 propensity score matching, 323 patients were enrolled in each group for analysis. The tumor recurrences were found in 124 patients (38.4%) and 118 patients (36.5%) and the median tumor free survival time was 10 months and 9 months in the LH group and OH group, respectively. The most common recurrence pattern was the intrahepatic recurrence, and the most common treatment was the transarterial chemoembolization. There was no significant difference of the relapse free survival curve between the LH and OH groups (P=0.763). In the entire cohort, no patient had recurrence or metastasis of specimen removal incisions or Trocar pores. No significant differences in the recurrence pattern and treatment between the LH and OH groups (P>0.05). Cox proportional hazards regression analysis showed that the age ≤60 years old, grade 2 of albumin-bilirubin grade, postoperative alpha fetoprotein >8 μg/L, tumor diameter ≥5 cm, multiple tumors, and low differentiation increased the recurrence of HCC after LH (P<0.05). The nomogram including these factors and combining with clinical practice was constructed, its consistent index for predicting the recurrence of HCC after LH was 0.704 [95%CI (0.659, 0.753)]. ConclusionIntrahepatic recurrence is still the most common pattern of postoperative HCC recurrence, and LH doesn’t increase risk of incision recurrence or implantation.
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.
