胃癌累及胰腺的外科治疗与预后(附120例报告)

目的探讨胃癌累及胰腺的外科治疗方法与预后的关系。方法回顾性分析我院1984年6月～2003年10月手术治疗累及胰腺的胃癌120例。结果本组120例中,根治切除组41例,姑息切除组23例,未切除组56例。根治组41例中经病理证实胰腺有癌细胞浸润者30例,占73.2%,淋巴结转移率为85.4%。其中No10、11淋巴结转移率为73.1%。术后102例得到随访,随访率为85%,1、3、5年的生存率分别为:根治切除组为73%、37%、17%,姑息切除组为22%、9%、4%,未切除组为9%、2%、0%。根治切除组1,3年生存率明显高于姑息性切除组和未切除组(P<0.05),5年生存率明显高于未切除组(P<0.01),但与姑息性切除组无显著性差异。姑息性切除组和未切除组1、3年生存率无显著性差异,但5年生存率明显高于未切除组(P<0.01)。结论胃癌累及胰腺的根治切除可提高1,3年生存率,选择合适的适应征是关键。姑息切除有助于改善生存质量,对改善预后意义不大。

The prognostic value of E-cadherin, α-, β- and γ-catenin in bladder cancer patients who underwent radical cystectomy

OBJECTIVES: To determine the value of the loss of expression of E-cadherin and cadherin associated molecules as useful markers for both prognosis and chemosensitivity in bladder cancer patients who have undergone radical cystectomy. PATIENTS AND METHODS: In 55 paraffin embedded specimens of radical cystectomy at our hospital from 1982 to 2000, the expression of E-cadherin, alpha-, beta- and gamma-catenin was examined by immunohistochemical staining. To evaluate the prognostic significance of these molecules, Kaplan-Meier survival curves were constructed and a statistical analysis was calculated by a log-rank test. A multivariate test (tumor stage, tumor grade, lymph node metastasis, configuration, the expression of E-cadherin, alpha-, beta- and gamma-catenin) was performed to detect prognostic markers. RESULTS: Normal expression was found in 33 cases (60.0%) for E-cadherin, 29 (52.7%) for alpha-catenin, 31 cases (56.4%) for beta-catenin, and 31 cases (56.4%) for gamma-catenin. The expression patterns for E-cadherin, alpha-, beta- and gamma-catenin were significantly correlated with each other (P < 0.01). Survival analysis showed a significant difference between normal and aberrant expression in each staining. A multivariate analysis revealed that the expression of alpha- catenin was an independent prognostic factor (P = 0.0191). In 23 patients that received adjuvant chemotherapy, there was a significant difference in survival between the normal and aberrant expression of alpha-catenin, but not other molecules. CONCLUSION: Alpha-catenin may not only be a good prognostic marker, but also one of key molecules that determine the chemosensitivities in patients with invasive bladder cancer.     

残胃癌临床诊治分析

目的分析和总结残胃癌的外科诊断、治疗及预后情况。方法对1990年以来收治的35例残胃癌的发病率、临床表现、治疗情况和预后进行回顾性分析。结果首次胃切除以胃溃疡为主,占65.7%,首次手术BillrothⅡ式占82.9%(29/35)。残胃癌早期缺乏特异的症状,主要为上腹部隐痛不适,首次手术距临床诊断残胃癌的间隔时间平均为16.3年。本组残胃癌手术切除率及根治性切除率分别为77.1%和54.3%,根治性切除患者1、3、5年生存率分为78.9%、52.6%、36.8%,Ⅰ期、Ⅱ期患者的5年生存率为72.7%。结论胃良性病行手术治疗时以BillrothⅠ式为首选,定期胃镜检查是早期诊断残胃癌的关键,根治性切除是治疗残胃癌的有效方法及影响残胃癌预后的重要因素。     

BcL-2、Bax、CD44V6在乳腺癌表达及预后的研究

目的探讨影响乳腺癌患者预后的因素,协助临床制定手术方式及术后治疗方案。方法选择80例各型乳腺癌患者的标本,应用免疫组化SP方法,检测乳腺癌组织中癌基因BcL-2、Bax及黏附因子CD44V6的表达情况。结果乳腺癌中BcL-2、Bax及CD44V6的表达情况与肿瘤组织学分级、瘤体直径。有无转移及患者术后存活时间均有显著性相关(P<0.05或0.01)。结论BcL-2高表达、Bax低表达、CD44V6低表达的患者组织学分级好,肿瘤体积小,淋巴结转移少,术后存活时间长,这部分患者可做肿物扩大切除而保留乳房或即使已做乳房切除,术后也可减少放疗及化疗剂量。     

Immunohistochemical localization of cathepsin D, proliferating cell nuclear antigen and epidermal growth factor receptor in human breast carcinoma analysed by computer image analyser: correlation with histological grade and metastatic behaviour

 

Aims:

The purpose of this study is to examine the relationship between immunohistochemical localization of cathepsin D (CD), proliferating cell nuclear antigen (PCNA) and epidermal growth factor receptor (EGF-R) in 65 cases of breast carcinoma in Japanese women and traditional prognostic factors such as histological grade, lymph node status, mitotic rate and clinical stage, in order to possibly identify some indicator(s) that may be specifically associated with prognosis.  

Methods and results:

Serial sections of 5-μm thick were cut from the archival formalin-fixed, paraffin-embedded tissue blocks, and processed for CD, PCNA and EGF-R immunostaining. The results were analysed by computer-based image analysis system. All samples showed a positive immunoreaction for cathepsin D in both the parenchyma and stroma. However, the staining area and intensity varied from cell to cell in the parenchyma and stroma as well as among samples. Subsequently, the evaluation of immunostaining for CD was separately performed in both the parenchyma and stroma (CDpar and CDstr, respectively) and the combination of both components (CDtotal). PCNA and EGF-R showed positive immunostaining almost exclusively in the parenchymal component of the carcinoma tissue specimens. CDtotal significantly correlated with the histological grade, PCNA index (PI), mitotic rate (MR), EGF-R and lymph node metastasis. Significant correlation was also demonstrated between CDpar and the histological grade, EGF-R and lymph node metastasis, or between CDstr and MR, EGF-R and lymph node metastasis. EGF-R correlated highly with the histological grade, MR score, lymph node metastases and recurrence-free survival.  

Conclusions:

Both the CD parameters and EGF-R are valuable indicators for predicting the biological behaviour of human breast carcinoma.     

Effect of metoprolol on death and cardiac events during a 2-year period after coronary artery bypass grafting

PURPOSE: To evaluate the effect of long-term treatment with metoprololafter coronary bypass grafting on death and cardiac events. METHODS: Patients in western Sweden on whom coronary artery bypass graftingwas performed between June 1988 and June 1991 were evaluatedfor inclusion during the first 3 weeks after surgery. Majorexclusion criteria were age >75 years, concomitant valvesurgery, traditional contraindications to beta-blockers andunwillingness to participate. Patients were randomized in adouble-blind fashion to 100 mg of metoprolollplacebo daily for2 weeks and thereafter 200 mg daily for 2 years. RESULTS: Of 2365 patients who were operated on, 967 were randomized toeither metoprolol (n=480) or placebo (n=487). Primary end points(death, non-fatal myocardial infarction, unstable angina pectoris,need for coronary artery bypass grafting or percutaneous transluminalangioplasty), were reached by 42 patients in the metoprololgroup (8·8%) as compared with 39 in the placebo group(8·0%) (P=0·73). Of all the patients randomizedto metoprolol, 34% withdrew from blind treatment prematurelycompared with 44% for placebo (P<0·01) CONCLUSION: Prophylactic treatment with metoprolol over a 2-year periodafter coronary artery bypass grafting did not reduce death orthe development of cardiac events. However, the 95% confidencelimits ranged from the possibility of a 30% reduction in eventsto a 68% increase in events if patients were treated with metoprololas compared with placebo.
