INTRODUCTION: Lymph node (LN) positive bladder cancer is a serious disease associated with a poor prognosis. Nevertheless even after radical cystectomy and lymph node dissection alone long-term oncologic control has been reported in a subset of these patients. Efforts have been made to stratify LN-positive patients according to various prognostic factors to make more individualized risk estimations. This review attempts to summarize the existing data on prognostic determinants in node-positive bladder cancer. EVIDENCE ACQUISITION: A literature search of the English literature was performed in October 2015 on PubMed using the search terms "bladder cancer", "node-positive" and "prognosis/outcome". Papers were only selected when separate information on the node-positive subpopulation was available. Data from prospective studies, meta-analysis or multi-institutional were selected primarily. EVIDENCE SYNTHESIS: Current 2010 TNM classification of nodal disease seems to have limited prognostic value. Several other nodal parameters such as number of positive nodes, number of resected nodes, LN density and extracapsular extension have been extensively evaluated and show potential in distinguishing prognostic subgroups. Although node-positive bladder cancer is often seen as systemic disease local tumor characteristics such as T stage and histological variants seem to remain important. Molecular markers are promising in stratifying patients with bladder cancer but need further validation in a specific node-positive subgroup. Neo-adjuvant chemotherapy seems to improve the prognosis of clinical node-positive patients and evaluation of response could help in selecting patients who benefit from consolidating surgery. Although retrospective studies convincingly suggest improved clinical outcome with adjuvant chemotherapy for pathological node-positive patients, these findings are not consistently confirmed in recent prospective studies. CONCLUSIONS: Future research should aim at the incorporation of prognostic variables into clinically applicable nomograms and identification of the subgroup of patients who will benefit from adjuvant treatments.
引言:淋巴结(LN)阳性的膀胱癌是一种预后较差的严重疾病。然而,即使仅行根治性膀胱切除术和淋巴结清扫术,仍有部分此类患者实现了长期肿瘤控制。人们已努力根据各种预后因素对LN阳性患者进行分层,以做出更个体化的风险评估。本综述旨在总结关于淋巴结阳性膀胱癌预后决定因素的现有数据。 证据获取:2015年10月在PubMed上使用搜索词“膀胱癌”、“淋巴结阳性”和“预后/结局”对英文文献进行了检索。仅当可获得关于淋巴结阳性亚群的单独信息时才选择相关论文。主要选择前瞻性研究、荟萃分析或多机构研究的数据。 证据综合:当前2010年的淋巴结疾病TNM分类似乎预后价值有限。其他几个淋巴结参数,如阳性淋巴结数量、切除淋巴结数量、LN密度和包膜外扩展,已得到广泛评估,并显示出区分预后亚组的潜力。尽管淋巴结阳性的膀胱癌常被视为全身性疾病,但局部肿瘤特征,如T分期和组织学变异,似乎仍然很重要。分子标志物在膀胱癌患者分层方面很有前景,但需要在特定的淋巴结阳性亚组中进一步验证。新辅助化疗似乎可改善临床淋巴结阳性患者的预后,评估反应有助于选择从巩固手术中获益的患者。尽管回顾性研究令人信服地表明,病理淋巴结阳性患者辅助化疗可改善临床结局,但这些发现并未在近期的前瞻性研究中得到一致证实。 结论:未来的研究应致力于将预后变量纳入临床适用的列线图,并确定将从辅助治疗中获益的患者亚组。
