进展期胃癌化疗效果不佳。分子靶向治疗是近年来进展期胃癌综合治疗的新手段。目前这些策略主要包括针对表皮生长因子受体(EGFR)通道的靶向治疗、针对血管内皮生长因子通道的靶向治疗、口服小分子靶向药物等。近期有关HER2、EGFR、VEGF、mTOR信号通路的靶向药物曲妥珠单抗、西妥昔单抗、贝伐单抗、阿帕替尼、索拉非尼、舒尼替尼、拉帕替尼、RAD001(everolimus)等综合治疗进展期胃癌的报道结果令人鼓舞。 相似文献

胃癌是中国常见的消化道恶性肿瘤,具有发病率和死亡率高、进展期患者占比高的特点。既往胃癌的治疗以化疗为主,HER2阳性胃癌可应用曲妥珠单抗。由于胃癌的高度异质性,以致胃癌的药物研发及临床研究进展不尽人意。近几年,随着免疫治疗的进展及新靶点在胃癌中的探索,胃癌治疗取得了重大突破。本文就胃癌靶向和免疫治疗研究进展作简要综述。 相似文献

胃癌在的全球范围内的发病率居癌症第四位,致死率居癌症第二位。标准的化学治疗方案在延长胃癌生存时间方面发挥了重要的作用。但由于多数胃癌在确诊时已处在进展期,因此当前的医学实践只能满足有限的治疗选择。在过去几十年中,关于胃癌发生的分子机制的研究不断获得新进展。通过靶向抑制人类表皮生长因子受体2(Her-2)来治疗进展期胃癌,为患者提供了新的治疗方案。曲妥珠单抗,是一种Her-2单克隆抗体,是第一种治疗转移性胃癌的靶向药物,它与以顺铂及5-氟尿嘧啶为基础的化学治疗的联合应用,可以使胃癌整体生存获益。而Her-2过度表达为靶向治疗提供了证据。因此,本文就近年来关于胃癌Her-2过度表达和胃癌的靶向治疗做一综述。 相似文献

近年来,放疗、化疗及手术联合治疗成为了头颈部鳞癌的主要治疗手段。然而,由放化疗带来的毒性作用不可避免地影响了治疗的依从性。分子靶向治疗作为一种新的生物治疗模式,在治疗头颈部肿瘤方面具有毒性作用小的特点,越来越受到关注。头颈部肿瘤的靶向治疗药物主要包括西妥昔单抗和贝伐单抗等,目前西妥昔单抗等靶向治疗药物已被FDA批准用于头颈部鳞癌的治疗。本文以西妥昔单抗和贝伐单抗为主,同时介绍一些正处于研究中的靶向治疗药物,探讨靶向药物在头颈部肿瘤治疗中的应用和进展。 相似文献

多学科联合治疗是局部晚期头颈部鳞癌的最佳治疗模式,而分子靶向药物也在近年应用到这一领域。由于头颈部鳞癌具有普遍的表皮生长因子受体(epithelial growth factor receptor,EGFR)的高表达,目前的靶向治疗主要针对这一靶点。西妥昔单抗作为一个人鼠嵌合的单克隆抗体,是目前唯一批准用于头颈部鳞癌的分子靶向药物。与单纯放疗相比,放疗联合西妥昔单抗能够显著改善局部晚期头颈部鳞癌患者的无进展生存和总生存,但与传统同期放化疗的比较无论在疗效还是不良反应方面尚不充分。随着诱导化疗在局部晚期头颈部鳞癌的研究进展,放疗联合西妥昔单抗为后续的治疗模式提供了新的研究思路。虽然RTOG 0522研究初步证明了在同期放化疗基础上再联合西妥昔单抗无法进一步提高疗效,但对于西妥昔单抗的化疗药物配伍的问题仍然值得探讨。而对于其他抗EGFR抑制剂而言,如何在现有证据基础上设计有针对性的临床研究是能否取得治疗更新的关键。 相似文献

在晚期胃癌的一线化疗方案中,蒽环类药物+铂类药物+氟尿嘧啶类药物组成的方案依然具有疗效和安全性;紫杉类药物+铂类药物+氟尿嘧啶类药物组成的化疗方案疗效和毒性并存;以S-1为基础的化疗方案显示了有效性和安全性.氟尿嘧啶类药物在非一线方案以及体力状况较差的患者中有效且安全.分子靶向药物联合化疗具有临床获益.疗效预测分子对选择化疗药物或分子靶向药物具有重要的意义. 相似文献

目前化疗仍然是晚期胃癌的主要治疗手段, 但尚无标准方案。与最佳支持治疗相比, 化疗可延长患者中位生存期, 提高其生存质量。近年来, 随着各种新型抗癌药物的出现, 化疗方案不断演进, 晚期胃癌的治疗有效率和生存期得到进一步提高。同时, 随着胃癌分子生物学研究的不断深入, 针对人表皮生长因子受体2(HER-2)、表皮生长因子受体(EGFR)、血管内皮生长因子(VEGF)的分子靶向治疗成为胃癌综合治疗的热点。化疗联合分子靶向治疗在晚期胃癌中显示出良好的治疗效果及前景, 但仍需在临床研究和实践中进一步调整和优化。本文将结合最新文献, 对晚期胃癌的化疗及分子靶向治疗进行综述。 相似文献

The first choice for treating patients with metastatic gastric cancer is chemotherapy, and combination therapy with fluorouracil, platinum, and trastuzumab has been established as the standard first-line chemotherapy. For further improvement of treatment outcomes, it is important to develop second- and third-line chemotherapy. In the first decade of this century, irinotecan and taxanes, cytotoxic agents, and various molecular targeted agents began to be developed as second-line therapy. Treatment with paclitaxcel weekly in combination with ramucirumab targeting vascular endothelial growth factor receptor 2 has become the first choice for second-line therapy. Immune checkpoint inhibitors are now being developed, and the current treatment strategies for advanced gastric cancer may undergo major changes in the future. This review summarizes the transitions and future prospects of clinical developments for second-line therapy in patients with advanced gastric cancer. 相似文献

A detailed molecular characterization of gastric cancer has been revealed by global initiatives and a number of new molecular agents are under investigation. Currently only trastuzumab, a monoclonal antibody for human epidermal growth factor receptor 2 (HER2), is clinically used for HER2 positive advanced gastric cancer patients and ramucirumab, a monoclonal antibody directed against the extracellular ligand-binding domain of vascular endothelial growth factor receptor (VEGFR)2, can be used in second line. However, despite the progress in gastric cancer treatment, the prognosis of stage IV gastric cancer patients remains dismal. To achieve a remarkable improvement in the prognosis of patients, a multidisciplinary treatment approach with the help of effective molecular target agents should be considered. So far the role of multidisciplinary treatment for stage IV gastric cancer is still uncertain due to limited available data and absence of long-lasting tumor control with systemic therapy. Herein, an overview of the latest developments of molecular targeted agents for gastric cancer in advanced stages, in the perioperative setting and in oligometastatic disease is provided. The possibility of a multidisciplinary strategy using molecular target agents and surgery for stage IV gastric cancer is also assessed. 相似文献

Gastric cancer (GC) is the most common gastrointestinal malignant tumor, with a gradual increasing incidence throughout the world. Mostly GC is diagnosed in its late stage. To date, there is no usable standardized treatment regimen for patients with advanced GC. Apatinib mesylate, small‐molecule vascular endothelial growth factor receptor‐2 (VEGFR‐2) tyrosine kinase inhibitor (TKI), has been approved as third‐line treatment for patients with advanced gastric adenocarcinoma in China, October, 2014. Till now, there is no case report about apatinib as first‐line treatment for patients with advanced GC in literature. We present an 83‐year‐old Chinese man with advanced gastric adenocarcinoma, who received apatinib as first‐line option and obtained clinical benefit within 2 weeks. The lung metastases disappeared completely and the liver metastases shrank significantly. The patient's progression‐free survival was 163 days and overall survival was 201 days. This paper reviews and discusses apatinib as a new targeted drug for patients with advanced GC by comparison with other effective molecular‐targeted therapy. 相似文献
