title: [Epidemiologic analysis of 72 carcinomas of the nasal cavity and paranasal sinuses].
abstract: OBJECTIVE
  The aim of this study is to define the epidemiological aspects of carcinoma of the nasal cavity and paranasal sinuses.
  
  
  METHODS
  We performed a retrospective study of 72 carcinomas of the nasal cavity and paranasal sinuses. Various sites, age and sex distribution, drug consumption, TNM stage grouping and treatment were reported.
  
  
  RESULTS
  The average age was 63. Seventy- five percent of patients (54/72) were male and 25% (18/72) female. The site of origin was paranasal sinuses in 46 patients (64%), 30 in ethmoid sinus, 15 in maxillary sinus and 1 in sphenoid sinus. Twenty-six patients (36%) were located in nasal cavity. Squamous cell carcinoma was the most frequent histological type in both localizations. The 5-year adjusted survival rate for all patients was 60% (IC: 54-66), 36% (IC: 28-44) for paranasal sinus carcinoma and 86% (IC: 79-93) for nasal cavity carcinoma. The 5-year adjusted survival rate according to the T distribution in 46 carcinomas paranasal sinus was 80% T2, 71% T3, 19% T4a and 6% T4b.(p = 0.0002).
  
  
  CONCLUSIONS
  Carcinoma of nasal cavity and paranasal sinuses represent a group of tumors that differ from the rest of carcinomas of the head and neck.
