在第6版和第7版美国癌症联合委员会（AJCC）分期手册之间，对膀胱癌分期指南进行了几次修改。此外，针对2010年监测、流行病学和最终结果（SEER）病例实施的协作阶段（CS）数据收集系统第2版（CSv 2）涉及收集三个新的部位特异性因素（SSF）：世界卫生组织/国际泌尿病理学会分级（SSF 1）、区域淋巴结转移大小（SSF 2）和结外扩展（SSF 3）。我们的目标是评估这些新的SSF，以帮助研究人员使用/解释，并描述未来需要解决的数据质量问题。评估了2004-2010年浸润性和非浸润性膀胱癌病例的分期趋势。在2010例病例中，使用AJCC第6版和第7版指南进行分期比较，并在相关亚组中进行SSF完整性/质量评价。从2004年至2010年，按阶段划分的经统计学调整的发病率和病例比例保持稳定。从AJCC第6版到第7版的变化没有引起阶段之间的实质性变化。SSF 1在82%的病例中具有已知值，高于传统的SEER分级/分化变量。SSF 2和SSF 3不太完整，在淋巴结受累的病例中，分别有41%和37%的已知值（根据CS淋巴结变量）。SSF 1比传统的等级/分化变量更完整，更容易解释。SSF 2和SSF 3不太完整，可能与数据质量问题相关，仅应在已知淋巴结受累的病例中使用。
Several changes were made to bladder cancer staging guidelines between the 6th and 7th editions of the American Joint Committee on Cancer (AJCC) staging manuals. Also, Collaborative Stage (CS) Data Collection System version 2 (CSv2) implemented for 2010 Surveillance, Epidemiology, and End Results (SEER) cases involved collection of three new site-specific factors (SSFs): World Health Organization/International Society of Urological Pathology Grade (SSF1), size of metastasis in regional lymph nodes (SSF2) and extranodal extension (SSF3). Our objective was to evaluate these new SSFs to assist researchers on use/interpretation, and to describe data quality issues to be addressed moving forward. Staging trends were assessed for invasive and noninvasive bladder cancer cases from 2004-2010. Among 2010 cases, staging was compared using the AJCC 6th and 7th edition guidelines, and evaluation of completeness/quality of the SSFs was performed in relevant subgroups. Age-adjusted incidence rates and proportions of cases by stage remained steady from 2004-2010. Changes from the AJCC 6th to 7th edition caused no substantial movement between stages. SSF1 had a known value in 82% of cases, which was higher than the traditional SEER Grade/Differentiation variable. SSF2 and SSF3 were less complete, with 41% and 37% having known values, respectively, among cases with lymph node involvement (according to CS Lymph Node variable). SSF1 was more complete and straightforward to interpret than the traditional Grade/Differentiation variable. SSF2 and SSF3 were less complete, may be associated with data quality issues, and should only be used among cases with known lymph node involvement.
