Abstract
Inverted papilloma (IP) is a relatively rare sinonasal benign lesion, peculiar in its etiology, clinical presentation and treatment. Its resemblance to other sinonasal pathologies and varied approaches, makes it an interesting disease. Recently there have been several advances in the management of IP. This article aims to summarize the contemporary developments thus enabling the readers to understand the years of research behind IP. To integrate the available literature on IP and study the current scenario in its management. A comprehensive literature review was done on Google Scholar and PubMed database using the following key words: "inverted papilloma", "Schneiderian", "sinonasal", "medial maxillectomy". Articles published in English were used. Articles published till May 2020 were reviewed. Years of research have aimed to gain more information regarding the epidemiology, histopathology, staging systems and surgical management of IP. To briefly summarize the research so far, it is safe to say that there exists an association between Human Papilloma Virus and IP. The Krouse staging system is the most commonly used. The treatment itself has changed from a conservative approach to a more aggressive excision with or without external approach and with or without chemoradiotherapy. In IP, whether or not associated with SCC, complete surgical removal of the tumour is advocated as the treatment of choice. With the advancements in endoscopic technique, surgeons have been using it to their advantage for the surgical evaluation and cure of IP, depending upon the stage. Endoscopic treatment is preferred, whereas for lesions less accessible endoscopically, or in those with peripheral extension, open surgery is indicated. Every patient requires counselling before discharge and thorough examination during the follow-up to detect any evidence of recurrence.

Abstract
Background: There is a paucity of reporting on recurrence patterns of de-novo sinonasal squamous cell carcinoma (DN-SCC) and inverted-papilloma-transformed sinonasal squamous cell carcinoma (IP-SCC). Method: A systematic literature review queried studies comparing recurrence patterns in patients with both DN-SCC and IP-SCC. Primary outcomes included local and regional recurrence and rates of distant metastasis. Of the 595 studies screened, eight were included. Results: Patients with DN-SCC had significantly higher rates of positive margins, advanced T classification (T3/T4), treatment with chemotherapy and radiotherapy. There were no significant differences in local recurrence or regional recurrence. Overall risk of distant metastasis was lower in IP-SCC. DN-SCC, compared to IP-SCC, is more likely to present with advanced TNM classification and have positive margins after surgical resection, which may affect rates of distant metastasis and recurrence. Conclusions: The findings in this study suggest IP-SCC may be a less aggressive malignancy compared to DN-SCC, with the possibility of a reduced role for adjuvant therapy in IP-SCC. Further studies are required to better understand differences in tumor biology and treatments strategies between IP-SCC and DN-SCC.

[PMID: 35141984 DOI: 10.1002/hed.26995] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 11/03/2021] [Accepted: 01/24/2022] [Indexed: 12/30/2022] Open
Abstract
Long-term survival and recurrence patterns of squamous cell carcinoma arising from inverted papilloma (IP-SCC) have not been thoroughly investigated. Four electronic databases were searched and primary studies describing overall survival (OS), recurrence, and mean time to recurrence of patients with IP-SCC were included for review. Our search yielded 662 studies. The 28 studies selected for inclusion identified 663 patients with IP-SCC. In 596 patients with reported T classification, 439 (73.7%) were T3/T4 on presentation. Of the 650 participants with recurrence data (local, regional, and distant), 155 (23.8%) experienced a recurrence, with an aggregate mean time-to-recurrence of 24.3 months. In 565 patients with 5-year OS rates, the aggregate 5-year OS was 62%. Based on the literature to date, IP-SCC is associated with a 5-year OS rate of 62%. 23.8% of patients experienced recurrence at a mean time of 24.3 months, suggesting the need for long-term surveillance.

Abstract
BACKGROUND Human papillomavirus (HPV) is an established prognostic marker in oropharyngeal squamous cell carcinoma. Currently, the role of HPV in sinonasal carcinoma is being explored. OBJECTIVES This systematic review addresses the role of HPV in sinonasal cancer, establishing the occurrence of HPV-positive cancers and the influence of HPV-positivity on prognosis in sinonasal cancer as well as the utility of the putative surrogate marker of HPV (p16) in sinonasal cancer. MATERIAL AND METHODS Studies were identified with searches of Medline via PubMed and Embase via OVID (4 May 2020). Articles on original research concerning sinonasal cancer and HPV in humans written in English were included. Case reports with less than five cases were excluded. RESULTS Initially, 545 articles were identified; 190 duplicate articles were removed leaving 355 articles for title/abstract screening. Title/abstract screening excluded 243 articles, leaving 112 studies assessed for eligibility. After full-text screening, 57 studies were included. All articles investigated the significance of HPV in sinonasal carcinomas. HPV was reported in approximately 30% of sinonasal squamous cell carcinoma (SNSCC), where it was associated with a better prognosis. In sinonasal cancer, p16 is associated with diagnostic pitfalls and a putative utility of p16 in SNSCC has yet to be established. HPV was not frequently reported in other types of sinonasal carcinomas, besides the recently described subtype, HPV-dependent Multiphenotypic Sinonasal Carcinoma. In other types of sinonasal carcinoma, HPV is not frequently found. CONCLUSION Approximately 30% of SNSCC are HPV-positive. HPV-positivity in SNSCC is associated with improved survival. HPV occurs only rarely in other sinonasal cancers. There is currently not sufficient evidence for p16 as a surrogate marker of HPV in SNSCC.

Human Papillomavirus in Sinonasal Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis. Cancers (Basel) 2020; 13:cancers13010045. [PMID: 33561073 PMCID: PMC7796014 DOI: 10.3390/cancers13010045] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Revised: 12/19/2020] [Accepted: 12/21/2020] [Indexed: 12/18/2022] Open
Abstract
Simple Summary The causative role of human papillomavirus (HPV) in sinonasal squamous cell carcinoma (SNSCC) remains unclear and is hindered by small studies using variable HPV detection techniques. This meta-analysis aims to provide an updated overview of HPV prevalence in SNSCC stratified by detection method, anatomic subsite, and geographic region. From 60 eligible studies, an overall HPV prevalence was estimated at 26%. When stratified by detection method, HPV prevalence was lower when using multiple substrate testing compared to single substrate testing. Anatomic subsite HPV prevalence was higher in subsites with high exposure to secretion flow compared to low exposure subsites. HPV prevalence in SNSCC followed the global distribution of HPV+ oropharyngeal squamous cell carcinoma. Taken together, this meta-analysis further supports a role for HPV in a subset of SNSCCs. Abstract Human papillomavirus (HPV) drives tumorigenesis in a subset of oropharyngeal squamous cell carcinomas (OPSCC) and is increasing in prevalence across the world. Mounting evidence suggests HPV is also involved in a subset of sinonasal squamous cell carcinomas (SNSCC), yet small sample sizes and variability of HPV detection techniques in existing literature hinder definitive conclusions. A systematic review was performed by searching literature through March 29th 2020 using PubMed, Embase, and Web of Science Core Collection databases. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed by two authors independently. A meta-analysis was performed using the random-effects model. Sixty studies (n = 1449) were eligible for statistical analysis estimating an overall HPV prevalence of 25.5% (95% CI 20.7–31.0). When stratified by HPV detection method, prevalence with multiple substrate testing (20.5%, 95% CI 14.5–28.2) was lower than with single substrate testing (31.7%, 95% CI 23.6–41.1), highest in high-exposure anatomic subsites (nasal cavity and ethmoids) (37.6%, 95% CI 26.5–50.2) vs. low-exposure (15.1%, 95% CI 7.3–28.6) and highest in high HPV+ OPSCC prevalence geographic regions (North America) (30.9%, 95% CI 21.9–41.5) vs. low (Africa) (13.1, 95% CI 6.5–24.5)). While small sample sizes and variability in data cloud firm conclusions, here, we provide a new reference point prevalence for HPV in SNSCC along with orthogonal data supporting a causative role for virally driven tumorigenesis, including that HPV is more commonly found in sinonasal subsites with increased exposure to refluxed oropharyngeal secretions and in geographic regions where HPV+ OPSCC is more prevalent.

Abstract
BACKGROUND Endoscopic skull-base surgery (ESBS) is employed in the management of diverse skull-base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull-base surgery have produced the International Consensus Statement on Endoscopic Skull-Base Surgery (ICAR:ESBS). METHODS Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence-based review or evidence-based review with recommendations format. Subsequently, each topic was written and then reviewed by skull-base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. RESULTS The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull-base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. CONCLUSION A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence-based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull-base community to embrace these opportunities and collaboratively address these shortcomings.

Abstract
BACKGROUND The survival difference between de-novo sinonasal squamous cell carcinoma (DN-SNSCC) and SCC arising from inverted papillomas (IPs) is unclear. The purpose of this study was to compare the outcomes between DN-SNSCC and IP-transformed SNSCC (IP-SNSCC) patients. METHODS In this retrospective review, we compared IP-SNSCC and DN-SNSCC cases from the Eye and ENT Hospital of Fudan University from 2010 to 2017. A total of 162 patients (39 IP-SNSCC and 123 DN-SNSCC) were included in our study. Demographics, tumor characteristics, treatment, and clinical outcomes were analyzed. RESULTS The median follow-up time in all cohorts was 56 (range, 5-109) months. There was no difference in age, sex, smoking history, alcohol consumption, tumor primary site, or disease stage between the IP-SNSCC and DN-SNSCC patients. We also did not find significant differences in overall survival and disease-free survival between IP-SNSCC and DN-SNSCC patients (p = 0.584 and p = 0.238, respectively). The 5-year local failure rate was 52.8% for IP-SNSCC patients, which was significantly higher than for those with DN-SNSCC (31.9%; p = 0.013). The 5-year nodal failure rate was 19.0% for IP-SNSCC patients and 8.5% for DN-SNSCC patients (p = 0.211). The 5-year distant metastasis rate was 8.0% for IP-SNSCC patients and 16.1% for DN-SNSCC patients (p = 0.318). CONCLUSION IP-SNSCC and DN-SNSCC patients have similar survival outcomes. IP-SNSCC seems to have exhibited a higher local failure rate in our study. We believe that IP-SNSCC is a highly aggressive disease that requires radical treatment. Prophylactic neck treatment should not be omitted in a subset of IP-SNSCC patients.

Abstract
BACKGROUND The role of human papillomavirus (HPV) in sinonasal squamous cell carcinoma (SNSCC) is not well understood. METHODS The National Cancer Database was queried for cases of SNSCC with known HPV status. Demographics, socioeconomic variables, TNM stage, histology, grade, treatment modalities, and overall survival (OS) through 5 years were compared between HPV-positive and HPV-negative tumors. Cox proportional hazard regression analyses were performed. RESULTS Seven hundred seventy (770) cases were identified; 526 were HPV-negative (68.3%) and 244 (31.7%) were HPV-positive. Patients with HPV-positive tumors were younger (58.0 vs 63.7 years, p < 0.0001). Nasal cavity (49.4%) tumors were more likely to be HPV-positive (p < 0.05) than maxillary (18.8%), ethmoid (18.8%), and frontal (18.2%) sinus tumors. Large cell nonkeratinizing (42.4%), papillary (42.1%), and basaloid (56.5%) tumors were more likely than keratinizing (25.2%) tumors to be HPV-positive (p < 0.05). Well-differentiated (grade I) tumors (9.0%) were less likely than higher grade tumors to be HPV-positive (p < 0.05). Gender, race, facility type, insurance type, median income, education level, Charlson-Deyo comorbidity score, overall stage, T stage, N stage, M stage, tumor size, treatment modality, surgical approach, and surgical margins did not vary by HPV status (p ≥ 0.05). HPV-positive tumors had higher OS than HPV-negative tumors (p < 0.0001). At 5 years, OS was 68.1% and 51.5% for HPV-positive and HPV-negative tumors, respectively. On multivariate analyses, HPV positivity remained a favorable prognostic factor (hazard ratio, 0.49; 95% confidence interval, 0.34-0.70). CONCLUSION HPV positivity is more common in nasal cavity SCC and nonkeratinizing SNSCC. It is also a favorable prognostic factor in SNSCC. Future studies on SNSCC should take HPV positivity into consideration.

Abstract
UNLABELLED Human papillomavirus 11 (HPV11) is an etiological agent of anogenital warts and laryngeal papillomas and is included in the 4-valent and 9-valent prophylactic HPV vaccines. We established the largest collection of globally circulating HPV11 isolates to date and examined the genomic diversity of 433 isolates and 78 complete genomes (CGs) from six continents. The genomic variation within the 2,800-bp E5a-E5b-L1-upstream regulatory region was initially studied in 181/207 (87.4%) HPV11 isolates collected for this study. Of these, the CGs of 30 HPV11 variants containing unique single nucleotide polymorphisms (SNPs), indels (insertions or deletions), or amino acid changes were fully sequenced. A maximum likelihood tree based on the global alignment of 78 HPV11 CGs (30 CGs from our study and 48 CGs from GenBank) revealed two HPV11 lineages (lineages A and B) and four sublineages (sublineages A1, A2, A3, and A4). HPV11 (sub)lineage-specific SNPs within the CG were identified, as well as the 208-bp representative region for CG-based phylogenetic clustering within the partial E2 open reading frame and noncoding region 2. Globally, sublineage A2 was the most prevalent, followed by sublineages A1, A3, and A4 and lineage B. IMPORTANCE This collaborative international study defined the global heterogeneity of HPV11 and established the largest collection of globally circulating HPV11 genomic variants to date. Thirty novel complete HPV11 genomes were determined and submitted to the available sequence repositories. Global phylogenetic analysis revealed two HPV11 variant lineages and four sublineages. The HPV11 (sub)lineage-specific SNPs and the representative region identified within the partial genomic region E2/noncoding region 2 (NCR2) will enable the simpler identification and comparison of HPV11 variants worldwide. This study provides an important knowledge base for HPV11 for future studies in HPV epidemiology, evolution, pathogenicity, prevention, and molecular assay development.

Abstract
Formalin-fixed, paraffin-embedded (FFPE) tissue specimens stored in pathology departments worldwide are an invaluable source for diagnostic purposes when fresh clinical material is unavailable as well as for retrospective molecular and epidemiological studies, especially when dealing with rare clinical conditions for which prospective collection is not feasible. Accurate detection of HPV infection in these specimens is particularly challenging because nucleic acids are often degraded and therefore, not suitable for amplification of larger fragments of the viral genome or viral gene transcripts. This review provides a brief summary of molecular methods for detecting alpha-HPV DNA/RNA in FFPE tissue specimens. We specifically address the key procedural and environmental factors that have the greatest impact on the quality of nucleic acids extracted from FFPE tissue specimens, and describe some solutions that can be used to increase their integrity and/or amplifiability. Moreover, commonly used methods for HPV DNA/RNA detection in FFPE tissue specimens are presented and discussed, focusing on studies using polymerase chain reaction as an HPV detection method and published after 1999. Finally, we briefly summarize our 22 years of experience with HPV detection in FFPE tissue specimens.

BACKGROUND Radiochemotherapy for anal cancer achieves a good clinical response, locoregional control, anal function preservation. However, oncologic outcomes can differ using radiotherapy plus fluorouracil and mytomicin vs. cisplatin and fluorouracil. METHODS Between 2000 and 2012, 27 anal cancer patients receiving radiotherapy combined with two different radiochemotherapy schedules, fluorouracil and mytomicin (group A) and cisplatin plus fluorouracil (group B). The Kaplan-Meier method was also used to estimate local control, overall survival and disease free survival. Statistical significance between curves was evaluated using the Log-rank test. RESULTS Complete pathological response was found in 85.2% of patients, with higher rates of response in the group A (100% vs. 63.6%, p = 0.039). No significantly difference was found between the two groups for the other endpoints. Low rates of both acute and late toxicities were recorded. CONCLUSION Radiotherapy plus fluorouracil and mytomicin provide a better complete pathological response than radiotherapy plus cisplatin and fluorouracil and a greater rate of anal sphincter function preservation. Globally, radiochemotherapy of the anal cancer provides excellent clinical outcomes with a good profile of acute and late toxicity, without difference between the two groups studied.

Radiotherapy for inverted papilloma: a case report and review of the literature. Radiol Oncol 2013; 47:71-6. [PMID: 23450506 PMCID: PMC3573837 DOI: 10.2478/v10019-012-0045-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2012] [Accepted: 08/08/2012] [Indexed: 11/20/2022] Open
Abstract
Background Sinonasal inverted papilloma (IP) is a rare, usually benign tumor arising from the respiratory mucosa of the sinonasal tract. Surgical resection is the treatment of choice. In histologically overt benign IPs (i.e. without associated malignancy) irradiation was employed only anecdotally. The patient with gross residual of benign IP after up-front surgery that was subsequently treated with irradiation is presented and the literature reports on the use of radiotherapy (RT) in this tumor type are reviewed. Case report After the surgical treatment the residuum in the region of the sphenoid and adjacent cavernous sinus was irradiated to 54 Gy in 1.8 Gy daily fractions. No recurrence or deterioration of olfaction, hearing or vision was observed 2.6 years post-RT. Review of the literature In the literature, six reports were identified with 16 patients describing necessary details on RT and outcome. Twelve of 14 cases (our case included) with gross or subtotal tumor resection and postoperative RT were locally controlled. The lowest and the median irradiation doses were 47.15 Gy and 56.5 Gy, respectively, and the follow-up period ranged between 0.5–20.5 years (median 7.8 years). Conclusions RT is safe and valuable treatment option in histologically overt benign IPs. It is indicated when the risk of tumor recurrence after surgery is increased and in inoperable tumors.

Abstract
BACKGROUND The aim of the retrospective study was to evaluate the effectiveness and toxicity of radiochemotherapy in patients with squamous cell carcinoma of the anal canal treated at a single institution. PATIENTS AND METHODS Between 1/2003 and 9/2010, 84 patients were treated with radical radiochemotherapy at the Institute of Oncology Ljubljana, Slovenia. The treatment consisted of 3-dimensional conformal external beam radiotherapy with concurrent chemotherapy (5-fluorouracil and mytomycin C), followed by brachytherapy or external beam boost. The toxicity of therapy and its effectiveness were assessed. RESULTS The treatment was completed according to the protocol in 79.8% of patients. The median follow-up time of 55 survivors was 53 months (range: 16-105 months). The 5-year locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS), overall survival (OS) and colostomy-free survival (CFS) rates were 71%, 68%, 81%, 67% and 85%, respectively. No treatment-related mortality was observed. The most frequent acute side-effect of the treatment was radiodermatitis (grade 3-4 in 58.2% of patients). LENT-SOMA grade 3-4 late radiation side effects were observed in 15 (18%) patients. In patients with brachytherapy boost a trend of less late side effects was observed compared to patients with external beam boost (P=0.066). On multivariate analysis, complete clinical disease response was identified as an independent prognostic factor for LRC, DFS and DSS, the salvage surgery for LRC and DFS, whereas Hb below 120 g/l retained its independent prognostic value for OS. CONCLUSIONS Radiochemotherapy provides an excellent disease control and the survival with preserving anal sphincter function in majority of patients. Surgical salvage with abdominoperineal resection for persistent or recurrent disease has curative potential.

Abstract
Sinonasal inverted papilloma (IP) is a benign but destructive tumor originating from the ciliated respiratory mucosa of the sinonasal tract. It can be associated with malignancy (squamous cell histology, in particular) and human papillomavirus infection has been investigated as a potential etiological factor linked to malignant alterations of IP. Surgery is the treatment of choice for IP, however, radiotherapy as an adjunct to surgery is indicated for IP with associated malignancy.
