AI Article Synopsis

  • Recent studies indicate a decline in the prevalence of oral leukoplakia (OL) in the US compared to earlier findings.
  • Researchers analyzed data from 16,128 participants in the NHANES III survey, revealing weighted prevalence rates of OL at 0.66% in males, 0.21% in females, and 0.42% overall.
  • The highest OL rates were found in males aged 40-49 and females aged 70 and older, with gingiva and buccal mucosa being the most common affected sites.

Article Abstract

Recent studies reported a tendency towards a lower prevalence of oral leukoplakia (OL), compared with the past. To assess the prevalence of OL in a representative sample of the US population, data from the oral mucosal tissue assessment and some other covariates of 16128 participants in the US National Health and Nutrition Examination Survey (NHANES III) were included. The clinical definition of OL was applied according to the WHO criteria. The weighted prevalence estimates of OL were 0.66+/-0.14% in males, 0.21+/-0.05% in females and 0.42+/-0.08% in total. The age peaks were at 40-49 years in males and at >or=70 years in females. The prevalence estimates were 0.37% for homogeneous OL and 0.06% for non-homogeneous OL. Gingiva (38.8%) and buccal mucosa (30.9%) were the most frequent locations. Compared to previous studies in the USA, a substantial decline of the prevalence of OL was shown.

Introduction: Renal cell carcinoma (RCC) is one of the most common types of urogenital cancer. The introduction of immune-based combinations, including dual immune-checkpoint inhibitors (ICI) or ICI plus tyrosine kinase inhibitors (TKIs), has radically changed the treatment landscape for metastatic RCC, showing varying efficacy across different prognostic groups based on the International Metastatic RCC Database Consortium (IMDC) criteria.

Materials And Methods: This retrospective multicenter study, part of the ARON-1 project, aimed to evaluate the outcomes of favorable-risk metastatic RCC patients treated with immune-based combinations or sunitinib.
