Abstract

Advanced bladder cancer (ABC) is an aggressive malignancy with a poor prognosis. For the last 30 years, the standard of care for this disease has consisted of combination chemotherapy with a platinum-containing regimen as first-line therapy. Cisplatin is the most active cytotoxic agent against bladder cancer, but because of competing comorbidities, many patients are ineligible for this agent and instead receive carboplatin. The two-drug regimen of cisplatin and gemcitabine was found to be better tolerated and have comparable efficacy as the four-drug regimen of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) in a randomized study of patients with advanced disease. Therefore, cisplatin (or carboplatin) and gemcitabine is the most commonly used first-line regimen in this setting. No agents have been approved by the Food and Drug Administration (FDA) for second-line therapy in ABC. If patients are eligible for additional systemic treatment at the time of progression, options include single-agent therapy such as a taxane or pemetrexed, though given the lack of standard approaches participation in a clinical trial should be strongly encouraged. Recent molecular characterization of ABC reveals significant genetic heterogeneity and actionable genomic alterations in the majority of tumors. Emerging therapies may effectively target known molecular drivers of ABC, including the FGFR2, EGFR/HER2, VEGF, MET, and PI3/AKT/mTOR pathways. Reports of dramatic and prolonged responses to targeted therapy provide additional support for the use of genome sequencing in the rationale selection of treatment for subsets of patients. The current focus of clinical trial development is to design molecularly driven studies that "match" tumors with driver mutations and appropriate targeted therapies rather than a "one-size-fits-all" approach based on clinical and pathologic parameters of disease. The hope of patients and clinicians alike is that this therapeutic approach combined with novel agents may usher in a new era of effective treatments for patients with ABC.

摘要

高级膀胱癌(ABC)是一种侵袭性恶性肿瘤,预后不良。在过去的 30 年中,这种疾病的标准治疗方法是使用含铂方案的联合化疗作为一线治疗。顺铂是最有效的针对膀胱癌的细胞毒性药物,但由于存在竞争合并症,许多患者不适合使用该药物,而是接受卡铂治疗。一项针对晚期疾病患者的随机研究发现,顺铂(或卡铂)和吉西他滨的两药方案比甲氨蝶呤、长春碱、阿霉素和顺铂(MVAC)的四药方案更耐受,疗效相当。因此,顺铂(或卡铂)和吉西他滨是该情况下最常用的一线方案。在 ABC 中,没有药物被食品和药物管理局(FDA)批准用于二线治疗。如果患者在进展时符合额外的全身治疗条件,可选择单药治疗,如紫杉烷或培美曲塞,但鉴于缺乏标准方法,应强烈鼓励患者参加临床试验。最近对 ABC 的分子特征分析显示,大多数肿瘤中存在显著的遗传异质性和可操作的基因组改变。新兴疗法可能有效地靶向 ABC 的已知分子驱动因素,包括 FGFR2、EGFR/HER2、VEGF、MET 和 PI3/AKT/mTOR 通路。针对靶向治疗的显著和持久反应的报告为在治疗患者亚组时基于基因组测序选择治疗方案提供了额外的支持。临床试验开发的当前重点是设计基于分子驱动的研究,将具有驱动突变和适当靶向治疗的肿瘤“匹配”,而不是基于疾病的临床和病理参数的“一刀切”方法。患者和临床医生都希望这种治疗方法与新型药物结合,为 ABC 患者带来有效的治疗新时代。
