- W2894480929 abstract "Background: Morphologically, oral SCC (OSCC) may present with verrucopapillary (VP) features. Those with VP features may have a different histologic presentation and different growth pattern. Histologically, papillary SCC, verrucous carcinoma and conventional OSCC (CSCC) with VP features are designated as the verrucopapillary (VP) variants. Aim: The objective of this study was to determine the clinicopathologic profiles of OSCC with VP features and to compare it with OSCC with non-VP features. Methods: A retrospective search of the Malaysian Oral Cancer Database and Tissue Bank System (MOCDTBS) at Oral Cancer Research & Coordinating Center (OCRCC), Faculty of Dentistry, University of Malaya on verrucopapillary OSCC (VP) and nonverrucopapillary OSCC (non-VP) cases diagnosed from 2004 to 2016 was conducted to identify suitable cases for this study. 23 cases of VP and 29 cases of non-VP were studied based on the inclusion criteria. Formalin-fixed paraffin embedded (FFPE) samples from surgical specimens of VP and non-VP were retrieved. All cases were initially reviewed by two oral pathologists and consensus achieved to subdivide into VP and non-VP group. Clinicopathologic parameters were analyzed using frequency and % (for categorical variables). The χ 2 test was used for appropriate P values. Results: The age group of VP patients ranged from 38 to 79 years old (mean age, 64.3 ± 11.23 years) while the non-VP group ranged from 20 to 81 years old (mean age, 54.1 ± 12.3 years). Both groups had a female predilection with a male to female ratio of 1:3.8 and 1:1.4 for VP and non-VP patients, respectively. Indians predominated in both the groups and the results were found to be statistically significant ( P < 0.05). Most cases of VP were located on the buccal mucosa (45.8%) while most of non-VPL cases were located on the tongue and floor of the mouth (75.9%). Most of non-VP (85.7%) cases presented with significant lymph node involvement when compared with the VP group (36%), ( P < 0.05). In the VP group, 29.2% were treated by surgical excision alone while 70.8% were treated with a combination of surgical excision with neck dissection. Conclusion: This study showed that patients with OSCC exhibiting VP features were significantly older (> 60 years old). The OSCC with non-VP features behaved more aggressively than the OSCC with the VP features necessitating surgical excision in combination with neck dissection as the preferred treatment modality." @default.
