“…Some observational studies have shown significant differences in recurrence rate among Krouse and Cannady stages, whereas other studies have found no such association between any classification system and recurrence . Furthermore, a meta‐analysis revealed an increased risk of recurrence between Krouse T2 and T3 stages (OR 1.51, 95% CI 1.09–2.09) but no difference between T1 and T2 and between T3 and T4 . One reason for a lack of association is the heterogeneity of certain stages, including Krouse T3/Cannady T2 and Krouse T4.…”

Morphologic, intraoperative, and histologic risk factors for sinonasal inverted papilloma recurrence

Objective Sinonasal inverted papillomas (IP) are benign neoplasms with a propensity for local recurrence. Many risk factors are reported, with little consistency between studies. This study aimed to comprehensively assess for demographic, imaging, histopathologic, and intraoperative risk factors for recurrence. Methods We performed a single‐center retrospective cohort study of patients with pathologically diagnosed IP without malignancy who underwent surgical resection between 1997 and 2018. Eligible patients were identified through a database maintained by the Department of Pathology. Logistic regression identified variables associated with recurrence, and conjunctive consolidation was performed to create a predictive model. Results Of 76 subjects, 37% (n = 28) had recurrence. Median follow‐up and time to recurrence were 2.9 (range 0.5–21.1) and 1.7 (range 0.2–13.0) years, respectively. Confirmed negative margins on histology were protective (odds ratio [OR] 0.25, 95% confidence interval [CI] 0.08–0.85). Frontal sinus involvement (adjusted odds ratio [aOR] 5.83, 95% CI 1.20–28.37), incomplete resection (aOR 9.67, 95% CI 2.24–41.72), and presence of dysplasia (aOR 4.38, 95% CI 1.01–19.10) were significantly associated with recurrence on multivariable analysis. A three‐level composite recurrence risk staging system was created by consolidating the above three variables. The recurrence risks of composite stage I, II, and III disease were 20%, 38%, and 100%, respectively. No demographic, imaging, staging, or surgical approach variables were associated with recurrence. Conclusion Frontal sinus involvement, incomplete resection, and dysplasia were significant risk factors for IP recurrence, whereas confirmed negative margins were protective. Creation of a composite staging system using the above variables may allow for risk stratification and a patient‐specific approach to postoperative IP management.

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 omi ed in a subset of IP-SNSCC patients. C 2020 ARS-AAOA, LLC. S.

BackgroundSinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represents a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology‐based topics spanning the field.MethodsIn accordance with prior ICAR documents, ICSNT assigned each topic as an Evidence‐Based Review with Recommendations, Evidence‐Based Review, and Literature Review based on level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses format, and completed sections underwent a thorough and iterative consensus‐building process. The final document underwent rigorous synthesis and review prior to publication.ResultsThe ICNST document consists of 4 major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology‐based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention.ConclusionAs an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.This article is protected by copyright. All rights reserved

Association of Krouse Classification for Sinonasal Inverted Papilloma With Recurrence

Abstract: Inverted papillomas classified as stage T3 according to the Krouse classification system presented a 51% higher likelihood of recurrence. Head and neck surgeons must be aware of this higher likelihood of recurrence when planning and performing surgery for sinonasal inverted papilloma.
