The comparative impact of histologic variants and grade has not been well described.
Salivary cancer histologies were profiled using hospital and population-based cancer registries. Multivariable models were employed to assess relationships between histology, grade, and survival.
On univariate analysis, histologic variants exhibited a wide spectrum of mortality risk (5-year overall survival (OS): 86% (acinic cell carcinoma), 78% (mucoepidermoid carcinoma), 72% (adenoid cystic carcinoma), 64% (carcinoma ex-pleomorphic adenoma), 52% (adenocarcinoma NOS), and 47% (salivary duct carcinoma) (p < 0.001). However, on multivariable analysis these differences largely vanished. Worsening grade corresponded with deteriorating survival (5-year OS: 89% [low-grade], 81% [intermediate-grade], 45% [high-grade]; p < 0.001), which was upheld on multivariable analysis and propensity score matching. Recursive partitioning analysis generated TNM + G schema (c-index 0.75) superior to the existing system (c-index 0.73).
Grade represents a primary determinant of salivary cancer prognosis. Integrating grade into stage strengthens current staging systems.
组织学变异和分级的比较性影响尚未得到充分描述。
利用医院和基于人群的癌症登记系统对唾液腺癌组织学进行分析。采用多变量模型评估组织学、分级与生存率之间的关系。
单变量分析显示,组织学变异呈现出广泛的死亡风险谱(5年总生存率(OS):86%(腺泡细胞癌)、78%(黏液表皮样癌)、72%(腺样囊性癌)、64%(多形性腺瘤癌变)、52%(未特指腺癌)和47%(涎腺导管癌)(p < 0.001)。然而,多变量分析时这些差异基本消失。分级恶化与生存率下降相关(5年OS:89%[低级别]、81%[中级]、45%[高级];p < 0.001),多变量分析和倾向评分匹配时此结果依然成立。递归划分分析生成的TNM + G模式(c指数0.75)优于现有系统(c指数0.73)。
分级是唾液腺癌预后的主要决定因素。将分级纳入分期可强化现行分期系统。
