bjective To investigate the correlation between expression of vascular endothelial growth factor(VEGF) of serum and tumor tissues and the clinical prognosis in patients with breast cancer. Methods The expressions of VEGF level of serum and tumor tissues in 44 patients with invasive duct breast cancer, 13 with benign breast diseases and 40 healthy controls. Serum VEGF level was measured by ELISA method. The protein expression of tissue VEGF, ER and C-erbB-2 were evaluated by immunohistochemistry LSAB method. Results Serum VEGF level and tissue VEGF expression in breast cancer were higher than those in benign breast diseases （P＜0.001）, and there was no significance in benign breast diseases and healthy controls （Pgt;0.05）. VEGF expression was correlated with lymph node metastasis (P＜0.01), ER and C-erbB-2 expression (P＜0.05, P＜0.01) and clinical stage （P＜0.01）. There were no statistical correlation between VEGF expression and age, tumor size (Pgt;0.05). Conclusion There is positively correlation between serum VEGF level and tissue VEGF expression, and between VEGF expression and clinic prognosis. Serum VEGF level may be one of important index of prognosis estimation in patients with breast cancer.
The use of Gore-tex artificial blood vessel in staged operation of arterialization was adopted in 19 cases having severe isehemic disorders of the lower extremities. Following 3 to 29 months after operation. with an average follow-up of 16.2 months. 16 cases had obtained better results, one cases had amputation because of thrombosis of the femoral artery and another one had developed thrombosis in the deep vein of the leg. It was considered that the application of short- sized Gore-tex artificial blood vessel in staged operation of arterialization to treat severe ischemic disorders of the lower extremities could provide satisfactory clinical resulst.
目的 初步探讨影响男性乳腺癌患者预后的因素。 方法 收集2003年1月－2011年12月经病理确诊、接受治疗、临床资料较完整的36例男性乳腺癌患者的临床资料。采用对数秩检验和Cox回归分析影响男性乳腺癌患者预后的因素。 结果 36例患者无进展生存期（PFS）为3～95个月，中位PFS为45个月。单因素分析显示：肿瘤直径（P=0.001）、阳性淋巴结（P=0.001）、TNM分期（P＜0.001）、手术方式（P=0.001）是影响预后的因素。多因素分析显示：阳性淋巴结（P=0.024）和TNM分期（P=0.022）是影响预后的主要因素。 结论 阳性淋巴结和TNM分期是影响预后的主要因素，以手术为主的综合治疗模式是提高男性乳腺癌患者生存率的重要措施。
ObjectiveTo investigate the prognostic factors for inflammatory breast cancer based on the data from West China Hospital with a relatively large sample. MethodsClinical data of 41 patients with histopathologically confirmed inflammatory breast cancer (IBC) who received treatment at West China Hospital Oncology Center of Sichuan University between January 2009 and December 2014 were collected and analyzed. Log-rank test and Cox regression model were used for statistical analysis. ResultsIn the study, negative estrogen receptor, negative progestrone receptor and positive human epidermal growth factor receptor-2 were identified in 58.5%, 61.0% and 34.2% of the inflammatory breast cancer tissues, respectively. Progress free survival (PFS) were between 2 and 60 months, with a median of 35 months. Univariate analysis showed that Tumor Node Metastasis (TNM) stage (P=0.016) and therapeutic effect (P=0.002) influenced the survival. Multivariate analysis showed that TNM stage (P=0.006), therapeutic effect (P=0.002), and anthracycline-taxane based chemotherapy (P=0.041) were the significant prognostic factors. ConclusionTNM stage is the major prognostic factor for IBC. Preoperative chemotherapy with paclitaxel-epirubicin combination can improve the PFS of IBC. Comprehensive treatment mode with operation is recommended for the treatment of IBC.
During the coronavirus disease 2019 epidemic, West China Hospital, Sichuan University explored a new management model to ensure timely diagnosis and treatment and regular follow-up for breast cancer patients. On the basis of previous internet Breast Cancer Information Management System, patient management WeChat groups were integrated to develop an online and offline interconnect management platform. Regular follow-up of patients was mainly conducted by telephone, with WeChat management group as auxiliary. Coronavirus infections were screened during telephone follow-up. In the meanwhile, patients who needed to be further treated would be identified and recommended to the outpatient follow-up. The new management model can improve the efficiency of follow-up management, on the premise of reducing the risk of coronavirus disease 2019 transmission for both health care providers and patients.
ObjectiveTo compare the impact of early enteral nutrition (EN) and parenteral nutrition (PN) on the postoperative efficacy of esophageal cancer through meta-analysis of relevant randomized controlled trial (RCT).MethodsPubMed, Medline, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to April 2018 to identify potential RCT which assessed clinical efficacy between EN and PN for postoperative patients with esophageal cancer. According to the inclusion and exclusion criteria, two researchers independently screened and evaluated literature. Meta-analysis was performed by RevMan 5.3 software.ResultsA total of 30 RCT studies were selected, including 3 969 patients. Meta-analysis results showed that: there was a significant difference between EN and PN in postoperative anastomotic fistulas (I2=0%, OR=0.67, 95%CI 0.45-0.99, P=0.04), postoperative pulmonary infections (I2=0%, OR=0.42, 95%CI 0.32-0.55, P<0.000 1), postoperative albumin levels (I2=38%, MD=0.78, 95%CI 0.51-1.06, P<0.000 01),time of first anal exhaust after operation (I2=0%, MD=–23.16, 95%CI –25.16-21.16, P<0.000 01) and postoperative incision infection (I2=0%, RR=0.36, 95%CI 0.21-0.64, P=0.000 5).ConclusionCompared with PN, early EN can significantly reduce the incidence of major postoperative complications and shorten the time of first anal exhaust after surgery. In addition, EN is superior to PN in improving nutritional status, increasing weight and reducing costs and side effects.
