Purpose: Endotype-driven treatment has been introduced in the management of chronic rhinosinusitis with nasal polyps (CRSwNP), and an understanding of the associations between phenotypes and endotypes of CRSwNP will be beneficial in identifying responders. We aimed to determine the correlations between clinical manifestations and type 2 inflammatory mediators of sinonasal tissues., Methods: Adult patients undergoing endoscopic sinus surgery for bilateral CRSwNP were prospectively enrolled. Tissue eosinophilia and type 2 mediator expression in tissue homogenates were assessed and correlated with clinical features, including symptoms, comorbidities, blood eosinophil counts, specific allergen immunoglobulin (IgE) testing, computed tomography (CT) scan findings, and Sino-Nasal Outcome Test-22 scores., Results: A total of 93 subjects were recruited in our study. Fifty-nine (63.4%) cases were identified as the eosinophilic endotype, demonstrating with higher rates of comorbidity of asthma, blood eosinophilia and a high ethmoid-maxillary ratio on CT images. To correlate of phenotypes with the inflammatory mediator profile, multivariate analyses revealed the associations of IgE expression in nasal polyp tissues with allergen sensitization (p = 0.042), CT ethmoid-maxillary ratio (p = 0.001) and tissue eosinophil counts (p = 0.022); the association of interleukin (IL-5) expression with the blood eosinophil percentage (p = 0.020); and the association of IL-13 expression with white blood cell count (p = 0.002) and central compartment-type inflammation (p < 0.001)., Conclusion: We demonstrated associations of IgE and IL-5 expression with clinical features of eosinophilic-type inflammation and a significantly elevated level of IL-13 in patients with central-compartment-type CRSwNP. These observations may be useful when considering the use of type 2 biologic treatment and require further validation studies., (© 2023.

Background: The margin status is an important prognosticator for the survival of patients with tongue cancer. Although a positive margin is associated with a poor prognosis, those with clear margins do not always have good clinical outcomes., Methods: We investigated the margin status, pattern of tumor invasion (POI), and tumor satellite distance (TSD) in 119 freshly treated tongue cancers and assessed their association with the characteristics and clinical outcomes., Results: A close or clear margin and POI were not associated with overall survival. Tumor satellites occurred in 92% of tumors and were significantly associated with betel nut exposure. Patients with TSD 0.5 mm had a higher incidence of local recurrence, shorter intervals to neck recurrence, and a higher propensity to contralateral or bilateral cervical nodal metastasis., Conclusion: TSD is associated with local recurrence, contralateral neck metastasis, and the overall survival of patients with tongue cancer.
