The recurrent sinonasal inverted papilloma (IP) could be transformed to sinonasal squamous cell carcinoma. We use protein expression patterns by immunohistochemical method to see whether the expression of p53, p16, p21, and p27 belongs to cell-cycle-regulators and PCNA (proliferating cell nuclear antigen) and Ki-67 the proliferation markers in sixty patients with sinonasal inverted papilloma, and 10 of them with squamous cell carcinoma transformation. Significantly elevated levels of Ki-67, p27, and PCNA in IP with squamous cell carcinoma transformation of sinonasal tract compared with inverted papilloma were revealed. No variation of p16, p21, PLUNC (palate, lung, and nasal epithelium clone protein) and p53 expression was correlated to sinonasal IP malignant transformation by multivariate survey. However, we found elevated PLUNC expression in IPs with multiple recurrences. Finally, we found that PCNA, p27 may interact with CDK1 which promote IP cell proliferation and correlate to sinonasal squamous cell carcinoma. Ki-67 could work throughout the cell cycles to cause malignant transformation. In conclusion, this is a first study showing the correlation of Ki-67, PCNA interacted with CDK1 might lead to malignant transformation. Elevated PLUNC expression in the sinonasal IPs was related to multiple recurrences in human.

Objective To compare genome-wide DNA methylation between samples of sinonasal inverted papilloma (SNIP) and squamous cell carcinoma (SCC) samples in order to identify aberrantly methylated genes that might be involved in malignant transformation. Methods Tissue samples were collected from patients. DNA methylation in C-phosphate-G islands and gene promoters was analysed using a DNA methylation microarray kit. The levels of mRNA or protein from aberrantly methylated genes were measured using real-time polymerase chain reaction or Western blot analysis. Results A total of 27 tissue samples were included in this study; 15 SNIP samples and 12 SCCs arising in SNIPs. A total of 11 201 nominally differentially methylated sites were observed between SNIP and SCC arising in SNIPs. Six sites were significantly different at P < 0.01 and contained three genes ( MIR661, PLEC and OPA3). These three genes were hypermethylated. In addition, the levels of mature miR-661 mRNA and PLEC protein were significantly upregulated in SCC tissues compared with SNIP samples. The levels of OPA3 protein were downregulated in SCC tissues compared with SNIP samples. Conclusions This study demonstrated hypermethylation and abnormal expression of the MIR661, PLEC and OPA3 genes, suggesting a role for their involvement in the malignant transformation of SNIP.

AbstractObjective:This study reports a case of a sinonasal inverted papilloma with spread to the temporal bone via the eustachian tube and subsequent transformation to squamous cell carcinoma.Method:An 81-year-old woman presented with sinonasal inverted papilloma which subsequently spread to the ear. A literature review of inverted papilloma was carried out based on a Pubmed search of studies published between 1987 and 2011, using the key words ‘sinonasal inverted papilloma’, ‘temporal bone inverted papilloma’ and ‘squamous cell carcinoma’.Results and conclusion:Sinonasal and temporal bone inverted papillomas may sometimes be linked through direct spread via the eustachian tube. Inverted papillomas have the potential for malignant transformation; careful monitoring of both the nose and ear is therefore required for inverted papillomas found in the nasopharynx.

BACKGROUND: Sinonasal inverted papilloma (SIP), a benign epithelial growth in the sinonasal region with epidermoid epithelial transformation, has been known for its invasiveness, recurrency, and its link with malignancy. Meanwhile sinonasal squamous cell carcinoma (SSCC) is an epithelial malignancy on squamous cells from the sinonasal region. Epidermal growth factor receptor (EGFR), Nuclear Factor kB (NF-kB), and Cyclin D1 are factors those might play important role in proliferation of SIP and SSCC. This research was conducted to investigate the expressions of EGFR, NF-kB and Cyclin D1 in SIP and SSCC.METHODS: A cross-sectional study by examining the EGFR, NF-kB, and Cyclin D1 immunohistochemical expressions of SIP and SSCC was conducted. Subjects whose blocks were used in this research, were diagnosed as SIP and SSCC at the Otorhinolaryngology-Head and Neck Surgery Clinic, Dr. Saiful Anwar General Hospital. Samples were selected, processed for inmmunohistochemistry, evaluated and statistical analyzed.RESULTS: Twenty-four SIP and 9 SSCC subjects with their paraffin blocks were selected. Clear immunohistochemical expressions of EGFR, NF-kB, and Cyclin D1 were observed for both SIP and SSCC. Significantly higher immunostaining levels of EGFR (45.6%, p=0.001) and NF-kB (42.2%, p=0.013) were observed in SSCC. Immunostaining levels of EGFR vs. NF-kB were moderately correlated (p=0.03, r=0.437), while the immunostaining levels of NF-kB vs. Cyclin D1 were strongly correlated (p=0.002, r=0.602).CONCLUSION: Expression of EGFR and NF-kB in SSCC were higher than the EGFR and NF-kB expression in SIP, suggesting that EGFR and NF-kB play important role in sinonasal malignancy.KEYWORDS: sinonasal, inverted papilloma, SCC, EGFR, NF-kB, Cyclin D1

Background: As most of the oral squamous cell carcinoma develop from precursor premalignant lesions, it would be helpful if the malignant transformation is detected early in premalignant state. The objective of the research was to study the role of immunohistochemical expression of p53 and Ki-67 in oral premalignant lesion and squamous cell carcinoma.Materials and Methods: The expression of immunomarkers p53 and Ki67 were studied on formalin fixed paraffin embedded tissue sections from human oral squamous mucosal lesion for duration of 1 year. Results: Of total 36 cases, 80% cases of keratosis without dysplasia showed basal pattern of p53 staining while 47.1% cases of squamous cell carcinoma showed p53 staining in all layers of epithelium. The median p53 Labelling Index of squamous cell carcinoma was more than those of keratosis with and without dysplasia though the result was statistically non-significant. 50.0% cases of keratosis without dysplasia and 83.3% cases of keratosis with dysplasia displayed Ki-67 immunostaining confined to basal and suprabasal layer whereas 94.1% cases of squamous cell carcinoma showed Ki-67 positivity in all layers of epithelium. Median Ki-67 Labelling Index increased from keratosis without dysplasia to keratosis with dysplasia to squamous cell carcinoma, difference being statistically significant. A positive and insignificant correlation was observed between p53 and Ki-67 Labelling Index.Conclusion: Increased expressions of Ki-67 and p53 in oral squamous cell carcinoma compared to premalignant lesion suggest that they may be useful indicator of malignant transformation in dysplastic lesion.
