[Results of nasopharynx cancer treatment: some prognostic factors]

42 cases of nasopharynx cancer treated between 1985 and 1995 in ENT and Radiotherapeutic Clinic of the Pomeranian Medical Academy were analyzed. In 15 patients (34.5%) planoepithelial carcinoma was found, in 9 (20.9%)--anaplastic carcinoma, in 6 (13.9%)--lymphoepithelial, and in individual cases--spindle-shaped and mucoepidermal carcinoma solidum. 34 patients were treated by radical irradiation (60-70 Gy doses) and 8--by palliative (20-35 Gy). In 7 patients neck dissection was carried out. Better results were achieved in older patients (over 60 years old) than in younger ones. Prognosis in women was better than in men. 5 years' survival rate for T1-2 group was achieved in 77% of cases. For T3-4 group it amounted to 48%; in N0-1--69% and in N2-3 group--52%. 71% patients with planoepithelial carcinoma, whereas only 48% with undifferentiated carcinoma survived 5 years. The rate of 56% of 5 years' survival time is comparable with good results of other authors.
