靶向治疗是转移性肾癌的一线及二线治疗手段,其药物从作用机制主要分为两类:血管内皮生长因子(VEGF)/血管内皮生长因子受体(VEGFR)和抑制mTOR途径.最近开发的药物,包括酪氨酸激酶抑制剂、单克隆抗体和mTOR抑制剂,能靶向作用于肾癌的酪氨酸激酶和细胞内通路,产生抗肿瘤作用.本文综述较有前景的靶向药物,包括舒尼替尼( Sunitinib)、索拉非尼(Sorafenib)、帕唑帕尼(pazopanib)、贝伐单抗(Bevacizumab)及替西罗莫司Temsirolimus. 相似文献

树突状细胞(DC)是目前发现强大的抗原提呈细胞(APC),能有效激发T细胞应答并诱导特异性细胞毒性T淋巴细胞(CTL)生成。肾癌是泌尿系常见的恶性肿瘤,发病率位于泌尿系肿瘤的第2位,其主要治疗方法是外科手术,化疗、放疗、激素治疗均不敏感。但是,由于肾癌是一种免疫原性很强的肿瘤,利用DC疫苗接种宿主、诱导或增强宿主防御功能、提高机体免疫系统对肿瘤的特异杀伤能力,已成为晚期肾癌免疫治疗中的研究热点。 相似文献

Renal cell carcinoma (RCC) accounts for approximately 2% of all cancer cases worldwide. Metastatic disease is often present at the time of diagnosis of RCC and its poor response to chemotherapy and radiotherapy causes poor prognosis. Immunotherapy is relatively effective for RCC, but the response rate is approximately 15-20%. Therefore, new therapeutic approaches are necessary for these patients with metastatic RCC. Recently, the mechanisms responsible for the growth of RCC have been clarified, and molecular targeted therapy has been developed. In this paper, we review the new molecular targeted therapeutic agents effective for RCC. 相似文献

Background
The recent development of multiple targeted agents for metastatic renal cell carcinoma (mRCC) has changed the treatment paradigm; hence the benefit and optimal timing of cytoreductive nephrectomy is being reevaluated.Objective
To determine primary tumor response to treatment with targeted agents in patients with mRCC.Design, setting, and participants
We reviewed the clinical and radiographic data of all mRCC patients seen at our institution between November 2004 and December 2009 without prior systemic treatment who received targeted therapy with their primary tumor in situ.Measurements
Two independent reviewers measured the diameter of primary and metastatic tumors at baseline and subsequent scans, using Response Evaluation Criteria Solid Tumors (RECIST) v.1.1 to assess disease response.Results and limitations
We identified 168 consecutive patients with a median 15 mo of follow-up and a median maximum tumor diameter of 9.6 cm. Median maximum primary tumor response was −7.1% (interquartile range: −14.0 to −0.1).A total of 61 patients had multiple studies available for evaluation. In 43 patients with <10% decrease in primary tumor within in the first 60 d, median maximum response was −7.2% at 154 d versus −24.5% maximum response at 174.5 d for 18 patients with ≥10% decrease in primary tumor during the initial 60 d.Conclusions
Decrease in primary tumor diameter >30% while on targeted therapy for mRCC is rare, with most patients demonstrating minimal or no decrease in primary tumor diameter. Early response predicts a better overall primary tumor response. 相似文献14.

PURPOSE OF REVIEW: To provide an overview and summary of the recent developments in the use of targeted therapy in the management of advanced kidney cancer. The focus is on publications within the last year. RECENT FINDINGS: The last year has seen several exciting developments in the targeted approach to managing advanced renal cell carcinoma. The benefits of small-molecule tyrosine kinase inhibitors have been demonstrated in two large-scale, phase III prospective, randomized controlled trials. There is growing evidence, some not yet published, that mammalian target of rapamycin inhibitors are effective in this disease and the roles of therapies directed at the receptor for vascular endothelial growth factor continue to be refined. SUMMARY: Recent published trials offer substantial hope for those patients with advanced kidney cancer, where before the outlook was often bleak. There is an expanding menu of potential agents in this disease, so-called targeted therapies, that are grounded in a growing understanding of the biology of kidney cancer. Many challenges and questions still remain, but there are encouraging signs of progress and hope for the future. 相似文献

Renal cell carcinoma is the most lethal of the common genitourinary neoplasms, with 30% to 40% of patients eventually dying from disease progression. Although the recent development of targeted therapies against kidney cancer has yielded substantially improved tumor response rates and progression-free survival, these agents are still not curative. The integration of systemic therapies with surgery still represents the best management for select patients with advanced disease. Specifically, consolidative surgery may play a vital role in the management of this challenging patient population. However, concerns remain regarding the potential for increased surgical morbidity complicating the integration of surgery after targeted therapy. Careful patient selection and specific precautions to increase surgical safety should be implemented. 相似文献

Advanced renal cell carcinoma (RCC) is resistant to chemotherapy and radiotherapy. Immunotherapy is relatively effective against RCC. However, the response rate is approximately 15–20%. Therefore, new therapeutic approaches are necessary. Recently, molecular mechanisms responsible for the proliferation of RCC are identified, and molecular targeted therapy is developed. Bevacizumab, sorafenib, sunitinib, axitinib, temsirolimus, everolimus are promising molecular targeted therapeutic agents for metastatic RCC, and will be used widely in clinics in the near future. In addition, combination therapy with molecular targeted therapy and other therapies including immunotherapy may also be developed soon. 相似文献

The treatment of metastatic renal cell carcinoma (mRCC) has recently evolved from being predominantly cytokine-based treatment to the use of targeted agents, which include sorafenib, sunitinib, bevacizumab (plus interferon alpha [IFN-α]), temsirolimus, everolimus, pazopanib, and most recently, axitinib. Improved understanding of the molecular pathways implicated in the pathogenesis of RCC has led to the development of specific targeted therapies for treating the disease. In Korea, it has been 5 years since targeted therapy became available for mRCC. Thus, we now have broader and better therapeutic options at hand, leading to a significantly improved prognosis for patients with mRCC. However, the treatment of mRCC remains a challenge and a major health problem. Many questions remain on the efficacy of combination treatments and on the best methods for achieving complete remission. Additional studies are needed to optimize the use of these agents by identifying those patients who would most benefit and by elucidating the best means of delivering these agents, either in combination or as sequential single agents. Furthermore, numerous ongoing research activities aim at improving the benefits of the new compounds in the metastatic situation or their application in the early phase of the disease. This review introduces what is currently known regarding the fundamental biology that underlies clear cell RCC, summarizes the clinical evidence supporting the benefits of targeted agents in mRCC treatment, discusses survival endpoints used in pivotal clinical trials, and outlines future research directions. 相似文献
