成人肾母细胞瘤的临床现状 总被引:5,自引:0,他引:5
肾母细胞瘤(nephroblastoma),又称作Wilhms瘤、肾胚胎瘤,是婴幼儿常见的恶性肿瘤,而成人发病少见。成人肾母细胞瘤诊断困难,疗效差,生存率低,3年生存率仅有24%^[1]。原因可能是由于发病零散,症状不典型,以至研究不深入,许多病例发现时已属晚期;其次可能由于发病少,没有形成明确的诊疗方案。本文对成人肾母细胞瘤的诊断和治疗作进一步的探讨。 相似文献

Methods Clinical data of six patients treated for WT combined with Nbm in Beijing Children's Hospital from 2006 to 2010 were reviewed retrospectively.The patients'ages ranged from five to 14 months.Two of the patients were female and four were male.The WTs were left-sided in four cases and right-sided in two cases.The Nbms were ipsilateral with WT in three cases,contralateral in two cases and bilateral in one case. The Nbms were single In three cases and multiple in three cases.WTs were all single and the maximum diameter was 3,4,8,10,11,and 12 cm respectively.Two paitents underwent nephrectomy.Nephron sparing surgery and upper and lower pole nodule biopsy was conducted in two cases,Nephrectomy and contralateral nephron sparing surgery was conducted in an additional two cases.Adjuvant chemotherapy included vincristine,actinomycin and doxorubicin. Results One patient had tumor recurrence 33 months after a 15 month regimen of postoperative chemotherapy. One patient had tumor recurrence and died after nephron sparing surgery 5 months after a 11 month regimen of chemotherapy.Four patients underwent 6 months of chemotherapy,and it was 9,12,and 21 months respectively after stop of chemotherapy.Another patient was still in chemotherapy. Conclusions Nbm is a pre-neoplastic proliferative process with high risk of developing WT.Chemotherapy may reduce the rate of Nbm malignancy.If Nbm is malignant or chemotherapy is invalid,nephron sparing surgery is recommended. 相似文献

Purpose
The purpose of this study was to evaluate whether initial diagnostic technique influenced the ability to identify anaplastic histology, to determine the time interval to diagnosis of anaplasia, and to delineate the incidence of discordant pathology in bilateral Wilms' tumor. We hypothesized that delay in diagnosis of anaplasia could affect time to appropriate surgery and intensive multimodality therapy.Methods
One hundred eight-nine children were enrolled in the fourth National Wilms' Tumor Study with synchronous bilateral tumors, 27 of whom were eventually shown to have anaplastic histology. Initial diagnostic technique, time interval to diagnosis of anaplasia, and the incidence of discordant pathology were determined.Results
Anaplasia was identified in 0 of 7 tumors by core needle biopsy, 3 of 9 tumors by open wedge biopsy, and in 7 of 9 cases by partial or complete nephrectomy. The mean duration of first chemotherapy regimen (DD or EE) was 20, 39, and 36 weeks, respectively, before anaplasia was identified at second surgery. Discordant pathology between bilateral tumors was identified on final tissue diagnosis in 20 patients. Only 4 patients had anaplastic tumors in both kidneys.Conclusions
Core needle biopsy did not identify anaplasia in 7 of 7 children. Open biopsy or partial/complete nephrectomy identified anaplasia at initial diagnostic procedure in 10 of 18 children. Twenty of 24 patients at final tissue diagnosis had discordant pathology between the 2 kidneys. Earlier interval incisional biopsy or resection may identify anaplastic histology and limit the duration of chemotherapy targeted to favorable histology for children with bilateral Wilms' tumor and anaplasia. 相似文献12.

PURPOSE: Vascular extension to the vena cava occurs in 4% of Wilms tumor cases and can reach the right atrium in up to 1%. When this happens the thrombus is usually not adherent to the vessel wall, and there is blood flow around it. Preoperative chemotherapy can cause thrombus regression and even resolution. If the thrombus persists after chemotherapy, surgery will be a challenge. On the other hand, if the thrombus invades the vessel wall, its removal may not be feasible. In this situation cavectomy is a good surgical strategy because it provides complete resection. The prerequisite for cavectomy is the absence of blood flow in the vena cava on preoperative Doppler ultrasonography. We report 3 cases of Wilms tumor with vena caval invasion in which cavectomy was performed, and discuss the principles, indications and operative technique. MATERIALS AND METHODS: A total of 171 patients with Wilms tumor were treated at our institution between 1984 and 2004. Of these patients 6 with intravascular extension of thrombus within the right atrium were treated with extracorporeal circulation, cardiac arrest and profound hypothermia, and 3 were treated with cavectomy. RESULTS: There were no instances of surgical complications or postoperative renal failure in our patients who underwent cavectomy. All remain well and free of disease. CONCLUSIONS: Cavectomy is a safe procedure for treating pediatric patients with Wilms tumor when there is extension and invasion of the vena cava wall without blood flow. 相似文献

目的 比较不同种类药物治疗良性前列腺增生(BPH)的疗效与差异,确定不同药物对不同患者的最佳适应证。方法 采用随机平行对照、多中心临床研究方法,对2002年9月至2003年12月906例BPH患者,随机进入选择性α-受体阻滞剂特拉唑嗪、多沙唑嗪、坦索罗辛与萘哌地尔;50α-还原酶抑制剂非那雄胺与爱普列特以及植物制剂舍尼通等7种治疗药物组。每3个月随访一次,国际前列腺症状评分(IPSS)与生活质量评分(QOL),最大尿流率(Qmax)与平均尿流率(Qave),前列腺总体积(TPV)与前列腺移行带体积以及残余尿量为观察指标进行疗效评价。根据不同指标基线水平将患者进行分层,比较各治疗组患者主观指标IPSS和客观指标Qmax的改善情况。结果 基线指标分析显示,全组主观指标IPSS评分和客观指标Qmax水平与TPV以及移行带体积呈明显相关性(P〈0.01)。至随访6个月时各类药物均使BPH患者的主观指标IPSS与QOL评分及客观指标Qmax与残余尿量有明显改善。各种药物对主客观指标的影响程度的组间比较显示,对IPSS的改善无显著差异;5α-还原酶抑制剂类药物爱普列特与非那雄胺可以使TPV和移行带体积均明显缩小(P〈0.05)。将患者以前列腺体积〈35.5cm^3和≥35.5cm^3分为两层,在非那雄胺治疗的患者中Qmax平均增加5.7ml/s和2.2ml/s(P〈0.01),在舍尼通、萘哌地尔及多沙唑嗪治疗组,≥35.5cm^3者症状改善更为明显(P〈0.05)。以IPSS〈20分和≥20分进行分层,各种药物的疗效均在≥20分时更为明显(P〈0.01)。结论 各种药物均可明显改善BPH患者的主、客观症状,各种药物的疗效均对基线IPSS评分较高的患者疗效更为明显。5α-还原酶抑制剂能明显减小前列腺体积,对于前列腺体积≥35.5cm^2者有更为明显的主客观疗效。 相似文献
