This study aimed to analyze the clinical characteristics and difference of survival rates between adult patients less than 40 years of age and those 40 years of age and older. METHODS A retrospective analysis was conducted using the database of patients diagnosed with OC-SCC between 1990 and 2013 in the Sun Yat-sen University Cancer Center, but patients older than 85 years, younger than 18 years, or died within 6 months of diagnosis were excluded. Patients were categorized into two groups the young group ( 0.05). The young group was more likely to receive adjuvant radiotherapy and/or chemotherapy (42.48% vs 26.91%, p  less then  0.001). The 5-year OS rate (71% vs. 57%, p  less then  0.001) and DSS rate (72% vs 58%, p  less then  0.001) in patients under 40 years were significantly higher than those for the older group. CONCLUSION Our findings suggested that OC-SCC in younger patients did not present at a more advanced stage. In addition, young age is an independent predictor for better survival.PURPOSE The role of tracheostomy in COVID-19-related ARDS is unknown. Nowadays, there is no clear indication regarding the timing of tracheostomy in these patients. METHODS We describe our synergic experience between ENT and ICU Departments at University Hospital of Modena underlining some controversial aspects that would be worth discussing tracheostomies in these patients. During the last 2 weeks, we performed 28 tracheostomies on patients with ARDS due to COVID-19 infection who were treated with IMV. RESULTS No differences between percutaneous and surgical tracheostomy in terms of timing and no case of team virus infection. CONCLUSIO
