Despite advances in surgical techniques, perioperative therapies and postoperative management, outcomes for patients with bladder cancer have largely remained unchanged. Current management of bladder cancer still relies on pathologic staging that does not always reflect the risk for an individual patient. Studies assessing molecular alterations in individual tumors are offering insights into the myriad of cellular pathways that are deregulated in bladder tumorigenesis and progression. Alterations in pathways involved in cell-cycle regulation, apoptosis, cell signaling, angiogenesis and tumor-cell invasion have been shown to influence disease behavior. High-throughput assays are now allowing multiplexed assessment of biomarker alterations, thereby enabling characterization of novel molecular subtypes of bladder cancer. Such approaches have also been used for discovery and validation of robust prognostic molecular signatures. The future of bladder cancer management will rely on the use of validated multimarker panels for risk stratification, optimal surgical management, and theranostic strategies to identify and target specific alterations in individual tumors.
尽管手术技术、围手术期治疗和术后管理取得了进展,但膀胱癌患者的治疗结果在很大程度上仍未改变。目前膀胱癌的治疗仍依赖于病理分期,而病理分期并不总是反映个体患者的风险。评估个体肿瘤分子改变的研究正在为膀胱肿瘤发生和进展过程中失调的众多细胞途径提供见解。已证明参与细胞周期调控、细胞凋亡、细胞信号传导、血管生成和肿瘤细胞侵袭的途径改变会影响疾病行为。高通量检测现在允许对生物标志物改变进行多重评估,从而能够对膀胱癌的新型分子亚型进行表征。这些方法也已用于发现和验证强大的预后分子特征。膀胱癌治疗的未来将依赖于使用经过验证的多标志物组合进行风险分层、优化手术管理以及采用诊疗策略来识别和靶向个体肿瘤中的特定改变。
