ABSTRACT
Malignant tumors of the nasal cavity, middle ear and paranasal sinuses are relatively rare registered malignancies. In 2014, 1012 new cases of this group of tumors were registered across Russia, among them, 88 new cases were registered in the NorthWest Federal District and 35 cases in St. Petersburg. According to the Tenth Revision of the International Classification of Diseases, this group of neoplasms is divided into two rubrics: C30 – malignant tumors of the nasal cavity and middle ear and S31 – malignant tumors of paranasal sinuses. However, IARC monographs and Russian disease incidence reference books consider these rubrics together. Purpose and objectives of the study. The purpose of this study is to analyze the prevalence of malignant tumors of the nasal cavity, middle ear and paranasal sinuses in reliance on the database of the PopulationBased Cancer Registry of St. Petersburg. Materials and methods of the study. The basis of this study is formed of 565 cases of malignant tumors of the nasal cavity, middle ear and paranasal sinuses according to ICD10 rubrics C30 and 31. For indices evaluation the authors used traditional methods. Standardized incidence rates are calculated based on the world standard of population structure. Data analysis. The authors performed precise analysis of data on malignant tumors of the nasal cavity, middle ear and paranasal sinuses according to the fourth sign of ICD10, calculated the average mortality rate and the proportion of patients with various stages of tumors, studied the specifics of histological structure of this group of tumors. Results. The incidence and mortality of malignant tumors of the nasal cavity, middle ear and paranasal sinuses are higher in men than in women. The percentage of the early stages has increased. Histological structure has generally retained its essential characteristics. Conclusion. For the first time in Russia this work presents an analysis of morbidity and mortality of malignant tumors of the nasal cavity, middle ear and paranasal sinuses at the population level according to the fourth sign of ICD10. The authors calculated a number of analytical rates.
