Becker C, et al. - Authors sought to scrutinize the impact of comorbidities and anemia on the outcome and survival in cases with sinonasal carcinomas by appraising medical records of 121 patients with carcinoma treated at a single quaternary medical care and cancer center between 2002 and 2015. It was discovered that comorbidity presented as an independent risk factor on overall, disease-free and disease-specific survival in patients with sinonasal carcinoma. A connection was illustrated between anemia with shorter overall survival. This is the first study evaluating comorbidity using the age-adjusted Charlson comorbidity index (ACCI) scoring system and focusing on patients with sinonasal carcinoma.
