The aim was to update information on oral proliferative verrucous leukoplakia (PVL), a disease of verrucous-like lesions with high risk of malignancy, and its biomarkers.
A systematic search of literature on PVL and its biomarkers showed 22 biomarkers that were investigated in 19 papers. A meta-analysis was possible for human papillomavirus (HPV), aneuploidy, Ki-67, and p53.
Aneuploidy was found consistently (I = 0%, P = 0.61) in 92% (95% CI 80%-99%) of the PVL cases. P53 positivity prevalence was 27% (95% CI 15%-40%) in two available studies (I = 0%, P = 0.64). With HPV and Ki-67, the most outlying studies needed to be removed and after that the pooled HPV positivity prevalence (I = 24%, P = 0.27) was 5% (95% CI 0%-14%) and for Ki-67 (I = 9%, P = 0.33) 14% (95% CI 6%-26%).
With the evidence of the current literature, aneuploidy could value as a biomarker of PVL but should be further validated.
本研究旨在更新有关口腔增殖性疣状白斑（PVL）的信息，该病是一种具有高度恶性潜能的疣状病变，且存在相关生物标志物。
对 PVL 及其生物标志物的文献进行系统检索，共显示 19 篇文献中研究的 22 个生物标志物。对人乳头瘤病毒（HPV）、非整倍体、Ki-67 和 p53 进行了 meta 分析。
92%（95%CI80%-99%）的 PVL 病例中一致发现非整倍体（I = 0%，P = 0.61）。两项可用研究中 p53 阳性率为 27%（95%CI15%-40%）（I = 0%，P = 0.64）。对于 HPV 和 Ki-67，需要去除最偏离的研究，然后 HPV 阳性率的合并（I = 24%，P = 0.27）为 5%（95%CI0%-14%），Ki-67 为 14%（95%CI6%-26%）。
根据当前文献证据，非整倍体可能作为 PVL 的生物标志物，但仍需进一步验证。
