JAMA Oncol:proposed-RPA分期系统可预测HPV相关口咽部鳞癌患者的生存

2016-10-19 MedSci MedSci原创

目前美国癌症联合委员会/国际癌症控制联盟(AJCC / UICC)的分期系统,不适用于HPV相关的口咽部鳞状细胞癌(OPSCC),因此迫切需要一个新的分期系统。 而近期口咽癌的国际协作网络发布了新的分期系统(ICON-S),可以用于HPV相关的OPSCC。 还有一个新的分期系统(proposed-RPA),来自于一项全国性数据库队列,这些患者接受放疗或手术治疗。 本项观察性研究,

目前美国癌症联合委员会/国际癌症控制联盟(AJCC / UICC)的分期系统,不适用于HPV相关的口咽部鳞状细胞癌(OPSCC),因此迫切需要一个新的分期系统。

而近期口咽癌的国际协作网络发布了新的分期系统(ICON-S),可以用于HPV相关的OPSCC。

还有一个新的分期系统(proposed-RPA),来自于一项全国性数据库队列,这些患者接受放疗或手术治疗。

本项观察性研究,纳入了HPV相关非转移性OPSCC患者,对以上三种分期系统进行比较。

研究共纳入了5626例患者(86.0%为男性,中位数[范围]年龄,58 [21-90]岁)。位数(范围)随访28.5个月(0.1-58.8)。

新分期系统proposed-RPA下识别的IA期,T1-2N0-2a;IB期,T1-2N2b-3;II期,T3N0-3;III期,T4a-bN0-3患者的3年总生存率分别为91%, 87%, 81%和70%。

这个新的分期系统和ICON-S,都可以对首次手术或放疗组患者的生存进行预测(所有log-rank P < .001)。

对所有患者进行分析时,AJCC/UICC系统、ICON-S和proposed-RPA,均可以预测患者的生存结局。但是AJCC/UICC不能区分I期和IVA患者的生存差异(log-rank P = .17)。

与其他系统相比,proposed-RPA可以提供卓越的预测信息。

proposed-RPA分期系统可以作为待选分期系统,需要进一步的研究来评估,该分期系统作为AJCC/UICC分期系统的一部分的可行性。
