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

Objective To evaluate the correlation between the ability to predict the attachment site of sinonasal inverted papilloma by computed tomography and the long-term surgical outcome. Study Design Retrospective cohort study. Setting Five tertiary medical centers. Methods Study patients underwent attachment-oriented resection of inverted papilloma. The primary outcome was tumor recurrence. Results Among 195 patients eligible for the study, focal hyperostosis was recognized on computed tomography in 65% (n = 127), in 71% of primary cases (n = 101), and in 50% of revision procedures (n = 26). There was a trend for a higher incidence of squamous cell carcinoma among the patients without detectable hyperostosis ( P = .051). Location of hyperostosis coincided with the actual tumor attachment site in 114 patients (90%). Discordance between these parameters did not differ significantly ( P = .463) between 11 primary and 2 revision cases. The overall rate of recurrence was 9.7% (n = 19), with a mean time to recurrence of 20 months (range, 7-96 months). The rate of recurrence did not correlate with any of the following: tumor stage, surgical approach, presence of squamous cell carcinoma, whether the surgery was primary or revision, and the presence or location of focal hyperostosis on computed tomography. Inverted papilloma recurred significantly more often (38.5%) when the intraoperative findings of the tumor attachment site did not match the location of hyperostosis observed on computed tomography (odds ratio, 6.5; 95% CI, 1.78-23.66). Conclusion Detectability of focal hyperostosis on preoperative computed tomography does not affect the long-term outcome of inverted papilloma resection.
