SERPINB3 and in situ carcinoma: Likewise, YAP- 1 IIDI scores did not differ between early (CIN1/CIN2) and late (CIN3/CIS) preinvasive OSSN lesions (Table 3).We did not notice differences in YAP-1 expression between keratinizing and non-keratinizing SCC (p >.05) or between T1/T2 and T3/T4 stages in invasive cancers (p >.05).
