Younger women are particularly affected by the increase in the incidence of vulvar cancer. The purpose of this study was to investigate how clinical characteristics differ depending on the patient´s age and what role the age of initial diagnosis plays in the prognosis. Patients andMethods: Included patients were divided into groups aged below or above 50 years. The disease-free survival (DFS) was calculated and a multivariate discriminant analysis was conducted.
Of the 300 patients, 79 were ≤50 years and 221 were >50 years. The median age was 64 years (19-96 years). There were no differences between the groups regarding lymph node (LN) status and distant metastasis, but T1 tumours were more frequent in patients ≤50 years (77% vs. 62%, p = 0.02). The DFS only differed between the groups when there were no LN metastases. The nodal status was the predominant prognostic factor for the DFS regardless of age. In node-free patients, the 5-year DFS was 49% for the ≤50 years group and 89% for the >50 years group (p = 0.008), whereas there was no difference if a LN was involved.
In node-free patients, the risk for recurrence is lower for patients older than 50 years.
年轻女性尤其受到外阴癌发病率增加的影响。本研究旨在探讨临床特征是否因患者年龄而异,以及初始诊断年龄在预后中起什么作用。
纳入的患者分为年龄<50 岁和≥50 岁两组。计算无病生存率(DFS)并进行多变量判别分析。
300 例患者中,79 例年龄≤50 岁,221 例年龄>50 岁。中位年龄为 64 岁(19-96 岁)。两组在淋巴结(LN)状态和远处转移方面无差异,但≤50 岁患者中 T1 肿瘤更为常见(77%比 62%,p=0.02)。DFS 仅在无 LN 转移时两组之间存在差异。无论年龄如何,淋巴结状态都是 DFS 的主要预后因素。在无淋巴结转移的患者中,≤50 岁组的 5 年 DFS 为 49%,>50 岁组为 89%(p=0.008),而有淋巴结转移时则无差异。
在无淋巴结转移的患者中,年龄>50 岁的患者复发风险较低。
