OBJECTIVES/HYPOTHESIS: To analyze the impact of different types of perineural invasion (PNI) in squamous cell carcinoma (SCC) of the oral cavity on overall survival and recurrence rate, with a special focus on histologic subtypes and tumor stage.
Retrospective case-control study with clinicopathological analysis.
Seventeen patients who received primary surgical treatment for SCC of the oral cavity with PNI were matched to a control group. In a histologic review, PNI was classified into subtypes according to an adapted Liebig classification. The term was used to describe tumor invasion into the nerve, whereas was used to describe circumferential growth around the nerve. Clinical charts were reviewed, and a Kaplan-Meier survival analysis was performed.
The recurrence-free survival rates were 47.1% versus 80.4% (PNI vs. matched control group, < 0.05), 60.0% versus 94.1% (PNI in stage I and II disease vs. matched control group, < 0.05) and 41.7% versus 73.5% (PNI in stage III and IV disease vs. matched control group, < 0.05). In most cases (n = 9) of PNI, both histologic subtypes (type A and type B) were present. Five cases exclusively showed type A, and three cases exclusively showed type B.
Perineural invasion in early disease oral carcinoma has a particularly high impact on survival. Both histologic subtypes showed a significantly worse recurrence-free survival rate when compared to the control group.
目的/假设:分析口腔鳞状细胞癌(SCC)中不同类型的神经周围浸润(PNI)对总生存率和复发率的影响,特别关注组织学亚型和肿瘤分期。
采用回顾性病例对照研究并进行临床病理分析。
将17例接受原发性手术治疗的伴有PNI的口腔SCC患者与一个对照组进行匹配。在组织学检查中,根据改良的利比希分类法将PNI分为不同亚型。术语“ ”用于描述肿瘤侵犯神经,而“ ”用于描述神经周围的环形生长。回顾临床病历,并进行Kaplan-Meier生存分析。
无复发生存率分别为47.1%和80.4%(PNI组与匹配对照组相比, <0.05),60.0%和94.1%(I期和II期疾病中的PNI组与匹配对照组相比, <0.05),以及41.7%和73.5%(III期和IV期疾病中的PNI组与匹配对照组相比, <0.05)。在大多数PNI病例(n = 9)中,两种组织学亚型(A型和B型)均存在。5例仅表现为A型,3例仅表现为B型。
早期口腔癌中的神经周围浸润对生存率有特别高的影响。与对照组相比,两种组织学亚型的无复发生存率均显著更差。
