[Malignant neoplasm of nose and paranasal sinuses in Lower Silesia in years 1992-2001].

UNLABELLED
Malignant neoplasms of the nose and paranasal sinuses occur rarely but due to late diagnosis and poor treatment effects still remain a serious problem. The aim of the study was the analysis of all nose and paranasal sinus neoplasms treated at Lower Silesia in the years 1992-2001.


MATERIAL AND METHODS
In the years 1992-2001 in Lower Silesia region there were 182 patients treated for malignant nose and paranasal sinus tumors. Males outnumbered females significantly with male : female ratio was 1.9:1. Principal management was combined therapy--surgery with radiotherapy in 84% of the cases. Radiotherapy alone was performed in 8.8% and chemotherapy as palliative treatment in 7.1%. Fifteen patients (8.2%) underwent radical neck dissection followed by radiotherapy.


RESULTS
The analysed group constituted 79.6% patients with epithelial tumors and 20.4% with nonepithelial tumors. Cases T3-T4 predominated in the material in amount of 77.9% (113). There were 15 T2 cases (10.4%) and none of T1. Most of the tumors (57%) arose from middle segment of ethmomaxillary sinuses. Upper segment tumors constituted 18.6% of cases and lower segment--10.4%. Enlarged lymph nodes were diagnosed in 8.2%. Survival rate analysis in patient treated in the years 1992-2001 revealed 37.9% (69) of 3-year survival and 30.2% (55) of 5-year survival.


CONCLUSIONS
Unsatisfactory results of treatment are an effect of a high advanced stage of the tumor while diagnosed. Its direct causes are: asymptomatic course of the disease, localization in complex anatomical structure, not enough experience among medical staff dealing with the disease very rarely.
