title: [Results of treatment in patients with paranasal sinus carcinoma. Analysis of prognostic factors].
abstract: Analysis was based on the results of successful and unsuccessful treatment of 137 patients with paranasal sinus cancer at the Oncology Centre in Warsaw between 1987-2002. Patients with clinical stages T3 and T4 constituted 87% of cases (110 patients). Radical treatment was performed on 84 patients. Five-year overall survival in 137 cases amounted to 27%; and survival without recurrence was 24%. Five-year overall and recurrence-free survial among patients treated with surgery and radiotherapy were 36% and 32% retrospectively. Multivariate analysis of 61 patients with complete data, who were treated with radical surgery and radiotherapy, emphasized the influence of prognostic factors on survival. A worse prognosis correlated with advanced locoregional T and N stage. It is evident that total dose greater than 6000 cGy had a clear impact on the results of treatment. It was also shown that planning with the manually and hand-measured isodoses impacted negatively on the survival in comparison with 2D and 3D planning. Analysis of recurrence-free survival showed that metastatis to the lymph nodes, and a manually-planned treatment method, had a negative impact on the results of treatment. It is asserted that local recurrences are the main cause of failure in cases treated with surgery and radiotherapy.
