BACKGROUND

Staging schemas have changed multiple times over the past 10 years.

OBJECTIVE

We sought to examine the impact of staging schemas on the distribution of stages at diagnosis over time.

METHODS

We examined the stage at diagnosis for melanoma cancer cases diagnosed between 1999 and 2006 using data provided by the Surveillance, Epidemiology, and End Results (SEER) and National Program of Cancer Registries (NPCR) programs. The staging schemas were summary staging 1977 (SS1977), summary staging 2000 (SS2000), derived SS2000, and SEER historic staging systems.

RESULTS

Melanoma was predominantly staged as a localized disease in all schemas. Using SEER data, the proportion of localized melanomas diagnosed in 2001 to 2003 using SS2000 was about 2.5% lower than the proportion diagnosed in 1999 to 2000 using SS1977, whereas the proportion of cases staged as regional was 2.7% higher using the SS2000 than SS1977. The distribution of stages for cases diagnosed in 2001 to 2003 using SS2000 was similar to that for cases diagnosed in 2004 to 2006 using a derived SS2000. Shift in stage distribution among SS1977, SS2000, and SEER historic staging was found to be about 6% (localized to regional) and about 17.5% (unknown to regional stage). The distribution of changes in stage observed for the SEER cases was not evident for cases from NPCR.

LIMITATIONS

SEER historic staging was not available for NPCR cases.

CONCLUSION

Changes in staging rules resulted in cases being moved from the localized to the regional stage and from unknown to the regional stage. Without staging rules that have been consistently applied to melanomas over many years, surveillance of prevention, treatment, and control of this condition is difficult.

背景

在过去的 10 年中，分期方案已经多次更改。

目的

我们旨在研究分期方案的变化对随时间诊断时分期分布的影响。

方法

我们使用监测、流行病学和结果（SEER）和国家癌症登记处（NPCR）计划提供的数据，检查了 1999 年至 2006 年间诊断的黑色素瘤癌症病例的诊断时分期。分期方案包括 1977 年总结分期（SS1977）、2000 年总结分期（SS2000）、衍生的 SS2000 和 SEER 历史分期系统。

结果

在所有分期方案中，黑色素瘤主要被归类为局限性疾病。使用 SEER 数据，与 1999 年至 2000 年使用 SS1977 诊断相比，2001 年至 2003 年使用 SS2000 诊断的局限性黑色素瘤比例低约 2.5%，而使用 SS2000 分期的区域性病例比例高 2.7%。使用 SS2000 诊断的 2001 年至 2003 年诊断的病例的分期分布与使用衍生的 SS2000 诊断的 2004 年至 2006 年诊断的病例的分期分布相似。在 SS1977、SS2000 和 SEER 历史分期之间，分期分布的变化约为 6%（局部至区域）和 17.5%（未知至区域）。在 NPCR 病例中，没有观察到 SEER 病例中观察到的分期变化的分布。
