Tumor diameter > 4 cm (p = 0.013), lymphovascular space invasion (LVSI; p < 0.001), the presence of lichen sclerosus (p = 0.019), p16 expression (p = 0.007), p53 expression (p = 0.012), HPV status (p = 0.021), lymph node metastasis (p < 0.001) and post-operative radiotherapy (p < 0.001) were significantly related to OS in univariate analysis. Here, TP53 is linked to neoplasm.
