This histological finding correlates with cervical invasion, lymph-vascular space invasion (LVSI), tumor size, positive resection margins, parametrial invasion, node metastases and advanced stage. Some authors have reported that PNI has no prognostic relevance, others have found that PNI is related to disease-free survival or overall survival (OS) at univariate analysis, and others have observed that it is an independent poor prognostic factor for OS. The evaluation of PNI status should be included in the decision-making process for planning adjuvant treatment. PNI has been found in 7.6-52.4% of vulvar carcinomas. This feature, which is strongly associated with depth of invasion, LVSI, tumor size, advanced stage and nodal involvement, is an independent prognostic variable for the risk of recurrence and death in most series. PNI should be evaluated routinely in histopathology reports of vulvar carcinoma and could help clinicians to tailor adjuvant treatment.
